Introduction
The major consequence of the Great Recession for Spain has been the spectacular rise of
unemployment rate. According to ILO,2 Spain scored top 5 major unemployment harmonized rate
countries in the World —behind Macedonia, Kosovo, Bosnia and Herzegovina, and South Africa
sorted from highest to lowest— in the year 2012. Unemployment harmonized annual rate in Spain
was 25.6 over Spanish active population according to EU statistics 3 or 26.4 according to OECD
database 4 at the end of the year 2013. These data was maximum Spanish unemployment rate from
1987 to 2013. According to euroindicators in January 2014,5 the EU28 and Spanish seasonally-

adjusted unemployment rate was 10.8 and 25.8 percentage points, respectively. This data have
scored Spain in the second position —behind Greece— in the ranking of major countries in the
European Union unemployment rate, and fifteen percentage points over the EU28 average.
In this context, value-added economic activities and economic growth without net
employment creation are in discussion in the Spanish society. According to Laborda,6 “the data
appear to assert greater survivability of large companies, especially those of 5,000 workers or
more”. Relevance of this study is largest Spanish firms evolution sorted by economic activities, and
its employment and added value projection in short-term.
The main question of this study is: Which Spanish economic activities had high employment
and high added value in the largest Spanish firms during the period 1971-2012? The secondary
questions are: What was the evolutionary dynamic of these economic activities? What was the
employment and added value trends of these economic activities? What were economic activities
bigger wealth generating during the period 1971-2012? Which was correlation between
employment and added value? Does data aggregation changes results of this study? Can be drawn
some projection of this study in the short-term?
For answering these questions this study is divided in seven chapters without including this
introduction and the appendices. The first chapter is the state of the art about the recent literature of
the Spanish economic activities of the big business in the last forty years. The second chapter is
about the data-set source, methodology description used in the evolutionary model, and discussion
about validity of this study. The third chapter shows results of the evolutionary model of this study,
the «microresults» of the economic activities outside the bottom left quadrant, evolutionary wealth
ranking, and the «macroresults» of the aggregation by quadrants of all economic activities. The
fourth are the answer to the questions. The fifth chapter expose conclusions may be extracted of the
results of this study. The sixth chapter are the extensions about the theme Overcoming the Crisis
that I would wish to investigate in future research with European Funds in a short time. The seventh
chapter are references. And, finally, appendix that it shows the annual results —plotted in the form
of graphics— of the evolutionary model.

1. Literature review
The majority of experts viewed added value as a multidimensional construct. “There is no one
definition of added value”. “There are a lot of things that could be in there and you could call all of
those added value”. “There are many ways of measuring what it means”. These views reflect the
diversity of perspectives uncovered in the literature review (de Chernatony, Harris & Dall'Olmo,
2000: 46). While some speak of «added value», others talk about «adding value» or «value-added»
(De Chernatony, Harris & Dall'Olmo, 2000: 42). In this study I use the term «added value» and it is
related to an accounting definition.
According to Gallizo (2000a), «value added» is defined by the increase of wealth generated
by the activities of a company in a given period, which is measured by the difference between the
production value reached in the period —sold, stored, and immobilized— and the procurement
related to that volume of activity. Therefore, it is a «value added production». It is also a «gross
value added» —GVA— because it does not compute depreciation and provisions in the section on
operating costs, but such provisions are considered an assignment in the distribution of value added.
It is also a «business value added» directly linked with the GVA of the National Accounts, by
obtaining a classification of income and expenses by nature. In this study the largest Spanish firms
are those who declare higher operational revenue in their annual accounts.
The production approach, which is also called the output approach, measures GDP as the
difference between the aggregation of business GVA less the value of goods and services used in
producing these outputs during an accounting period (Viet, 2009: 4-14). The total economy
comprises the following institutional sectors in the System of National Accounts:
a) Non-financial corporations (divided into public, national private, and foreign controlled);
b) Financial corporations (divided into public, national private, and foreign controlled);
c) General government;

d) Non-profit institutions serving households; and
e) Households.
The subject of this study are the largest non-financial Spanish firms.
Daems (1987: 73-91)7 developed a test to analyze the underlying factors to the growth of big
firms. He provided some puzzling facts, such as the astonishingly high level of large U.K. firms in
real per capita terms among the European countries or, on the contrary, the surprisingly low level of
Spanish large firms in the same terms. Possible explanations were low R&D levels and the revealed
comparative advantage of a country against the set of sectors more conducive to giant firms. The
comparative advantage of Spain was not conducive to the developing of trademarks, at least until
1970. Oranges and fruits, iron ore, lead, pyrites, wine, and oil were unlikely candidates for
trademarks. Even the late growth of industrial exports was linked to non trademark sectors:
shoemaking and shipbuilding. During the period 1974-1990 Spain begun to show a very
competitive profile in one particular sector typically trademark led: vehicles. Spain was one of the
major world cars exporter in 1990 (Carreras & Tafunell, 1999: 303-304).
Carreras & Tafunell (1999: 281-283) analyzed the sectoral composition of the 200 largest
Spanish firms from 1917 to 1990. In the years 1974 and 1990, ordered by the number of firms, top
five economic sectors were manufacturing, finance, utilities —electricity, gas, water, and telephone
—, construction and public works, and transports. They also showed the distribution of the fifty
largest Spanish manufacturing enterprises sorted by the SIC American sectoral breakdown.8 In the
years 1974 and 1990, the group with greater number of firms is transportation equipment in both
years, followed by chemicals in the year 1974 and electrical machinery in 1990.
This current study is conducted from the point of view of the Spanish economic activities,
rather than an industrial sector study, because service firms —the tertiary sector— are included. In
the same way, this study is not a sectoral economic study because agriculture, livestock and
fisheries —the primary sector— is not included. Summarizing, this study focuses on the largest
non-financial Spanish firms engaged in economic activities of the secondary and tertiary sectors.

The most important literature for this study is the Spanish book The Big Firm in Spain. A
process of concentration and dependence (Sánchez, 1998). Joan-Eugeni Sánchez 9 argued that a
double process of concentration and dependence had occurred with the largest firms that were
operating in Spain, considering these as fundamentals in the economic activity. He analyzed the
general features of the largest firms in Spain through the evolution of variables provided by the
annual special issues —The (…) largest Spanish firms— of the Spanish journal Fomento de la
producción, the same dataset I have used for this study. He restricted the sample to the 1,000 largest
Spanish firms, measured by their operational revenue, so do this study but only 711 firms on
average in the period 1971-2012. He wrote an entire chapter to contextualize the structural and
cyclical trends of the Spanish economy during the period 1973-1994. He realized six cross-sections:
1973, 1976, 1981, 1986, 1991, and 1994. The innovation of this study is that I realize a longitudinal
section from 1971 to 2012 of the largest Spanish firms.
Sánchez analyzed changes in the structure of Spanish largest firms through the evolution of
the number of enterprises, operational revenue, added value, own resources, profit or loss, and
apparent and real productivity by sectors —industry, construction, and services— and by economic
activities —the first two digits of the NACE firm—. His results showed that the higher economic
activity by number of firms (table IV.2: 76) and by relative operational revenue (table IV.4: 82) was
big stores. The higher economic activity by relative added value per operational revenue was
communications (table IV.6: 88). The higher economic activity by total people employed was
construction, and by average employment per firm were rail transport in the year 1973 and
communications in 1994 (table V.2: 102). The higher economic activity by apparent productivity,
measured by added value per employee, was energy and water (table V.3: 109). The data source of
this study ends in 2006 and my desire was to get to the present, I have supplemented it with other data
source that has forced me to convert NACE 10 in the economic activities code of the first source.
There is an interesting study of Rodríguez (2011: 7) that analyzed the impact of the current
Economic Recession had on Spanish employment and GVA in 2009 through the correlation of

annual variation in real GVA and employment from 2008 to 2009 plotted in four quadrants. It
showed that there were 11 industries in the top right quadrant —GVA and employment growth rates
above the national average—: health, veterinary and social services; public administration;
education; personal services; domestic staff; agriculture, livestock and hunting; hospitality;11
transports and communications; real-estate and business services; food, beverages and tobacco; and,
trade and repair. There were 2 industries in the top left quadrant —GVA growth rate above the
national average and employment growth rate below the national average—: fishing and chemical.
There were 7 industries in the bottom right quadrant —GVA growth rate below the national average
and employment growth rate above the national average—: electric power, gas and water;
manufacture of coke, refined petroleum products and nuclear fuel; financial intermediation; paper,
publishing and printing; rubber and plastics; extraction of energy products; and, machinery and
equipment. Finally, there were 9 industries in the bottom left quadrant —GVA and employment
growth rates below the national average—: transport material; electrical, electronic and optical
equipment; miscellaneous articles; other mineral extraction; leather and footwear; metallurgy and
metal products; textile and confection; other non-metallic mineral products; and, wood and cork.
The originality of this study is because I analyze the correlation between added value and
employment of the secondary and tertiary economic activities of the largest non-financial Spanish
firms during the period 1971-2012 through four quadrants whose meanings are: high added value
and high employment —economic activities located in the top right quadrant—, high added value
and low employment —the top left quadrant—, low added value and high employment —the
bottom right quadrant—, and low added value and low employment —the bottom left quadrant—. I
have not found literature review with this idea.
In the context of the European debate on «jobless growth» in the 1990s, Pianta (2003: 9)
explained that the evidence points to an extensive process of restructuring in many manufacturing
sectors where the growth of value added is not matched anymore by increases in jobs. The idea of
relating employment and added value emerged from Pianta (2003: 6) that related “[...] the most
accurate description of the economic relevance of innovations [measured by share of new products
in sales] to the employment performance [measured by percentage change in employment] of 20

manufacturing industries in four EU countries [...]” where “ICT industries (computing,
telecommunications, precision instruments and other transport, including aerospace) are generally
in the top right quadrant [...]” and “Traditional industries (textiles, wearing apparel, leather and a
few others) tend to concentrate in the bottom left quadrant [...]”. My hypothesis is that largest added
value employment economic activities would must be high technological or intensive knowledge
ones (Gencat, 2007, 2008, 2009), and these activities would be —or not— bigger employment
generating. I expect that for Spain it will not be so.
Finally, I want to point out that the idea of modeling the evolution of the economic activities
represented by the largest Spanish firms in a dispersion diagram emerged from Hans Rosling,12 and
I believe that this study is the first time Rosling evolutionary model is applied in the correlation of
added value and employment.
Summarizing, this study analyzes evolutionary dynamic of the economic activities, and added
value and employment trends, of the largest non-financial Spanish firms, measured by their
operational revenue, engaged in economic activities of the secondary and tertiary sectors during the
period 1971-2012. The goal is to determine which Spanish economic activities have generated the
largest wealth: bigger added value and higher employment.

2. Methodology
2.1. The source of the dataset
According to Sánchez (1998: 21), Fomento de la producción dataset is a homogeneous series,
not very common in the landscape of social and statistical information in Spain, and widely
accepted and disseminated in the Spanish business and academic fields. The availability of a series
of about 40 years and collected under the same homogeneous criteria open the option of a
diachronic analysis of great interest.
However, it is important to clarify that business data published by Fomento de la producción
are a voluntary response of the major Spanish companies at the request of the journal, and its
accuracy and veracity is understood due to the objective of social transparency in all
entrepreneurship. The authors of Fomento de la producción have supplemented the missing data
where it has been possible with other information sources, often in very few occasions for self-esteem.
Also these authors want to point out that in any case their work aims to achieve the
infallible qualification because the objective was just to get a guidance document. I subscribe all
these constraints for this study.
The idea of publishing the Spanish journal Fomento de la producción about industry,
commerce and finance in Barcelona was thanks to a journalist from Huesca called Feliciano
Baratech.13 The first exemplar published of this journal was in the year 1945 with fortnightly
appearance. Actually, this journal has a web page where is possible to consult the Spain 25,000
database.14 The query of this online database, and electronic ones —Spain 25,000, Spain 27,000 and
Spain 30,000 (Fomento de la producción, 1988-2011)—, did not produce the expected results
because added value data was not available. Of course, other database were consulted but with

failed results because there were not available added value data of the largest Spanish firms.15 More
over, other databases exist but with restricted access.16
So, the next step was consult the availability of the journal Fomento de la producción in the
common catalogue of the universities of Catalonia. The results of this consultation showed that
from 1970 there was a Spanish annual special issue called The (…) largest Spanish firms (Fomento
de la Producción, 1970-2006). The consult in situ of available annual special issues —the whole
collection were available in the National Library of Catalonia— show me the possibility of a
longitudinal section of the largest Spanish firms because operational revenue, quantity of
employment, added value, and economic activity classification of the largest Spanish firms were
available from 1971 to 2006. A further problem was low coverage of the variable added value.
My desire from the beginning was to finish this study closest the current year for analyzing
the involvement of the Economic Recession in Spain —from 2009 to 2013—17 on the employment
and added value of the largest non-financial firms. To meet this objective was necessary to expand
the dataset. Beyond 2006, I only found a dossier within the journal entitled “The first Spanish

companies to (...)” (Fomento de la producción, 2008-2012) of around 200 companies. So, I
supplemented these data with the online Iberian Analysis System Balances database, called SABI.18
This database has restricted access for students, stores financial company information and
business intelligence for 2,000,000 Spanish firms from 1989 to the current date, and all the
necessary data for this study —NACE 2009 primary code, operational revenue, number of
employees, and added value— were available and exportable. The problems encountered were that
the drop-down menu on the main page did not select the years prior to 2002, the reclassification of
the NACE according to the economic sector classification of the journal, and the faster consumption
of available financial credit for exporting data.19 Finally, I got to export top 500 Spanish firms by
operational revenue from 2006 to 2012.
According to Sánchez (1998: 21-22), simultaneity of two different data sources —Fomento
de la producción and SABI— can break the continuity of the serial homogeneity of this study. The
value of time series to establish the trends is know. It may be questionable in its absolute validity as
timely and quantitative information, but it allows to detect trends in the processes, even the values
may be questionable. This is the case in this methodology. However, this study can be considered
that provides information of interest, especially from an evolutionary point of view.
So, I had the data necessary for my study. The problem was the labor cost of this job. The
solution left was to scan the data; to write all data for each year in a spreadsheet —name of the firm,
name of the economic activity classification, nominal monetary operational revenue, quantity of
employment, and nominal monetary added value—; to order firms by economic activities when the
data source was the journal, or to reclassify firms by economic activities when the data source was
SABI; and, to add the totals. Lack of time has restricted sample size of this study of a total of 67,125
available companies to 28,461 firms, 711 per year on average,20 a coverage on average of 42.4
percentage points for the periods 1971-1986 and 1989-2012. Next table shows the annual coverage
of this study:

19: Ten days' work in different Universities in two months —when financial credit was restored— were required.
20: The constraint of around 660's firms used in this study is because it was the equivalent to four hours of my job.

Notes: The years 1970, 1987 and 1988 have not been included in the total because added value data were not available.
The total firms included in the years 1971 and 1972 are the number of firms used in this study —200 and 550 instead of
704 and 1,000, respectively— because original source did not offer any added value data for the others companies —
504 and 450, respectively—, for this reason the study has full coverage in these years. For the years 1974, 1975, 1976
and 1977 the data of this study was in correspondence with the aggregate results of the economic activities carried out
by the authors of Fomento de la producción. It was a pity this practice did not continue in subsequent years. The data of
the year 1974 was available in Fomento de la producción (1975). For the period 2006-2012 the simultaneous use of two
datasets —Fomento de la producción and SABI— causes the existence of duplications. The total firms included in the
period 2007-2012 are the number of firms used in this study, for this reason the study has full coverage in this period.
The journal data override SABI data for all replicas. The year 2007 was available in Fomento de la producción (2008).
The dossiers “The first Spanish companies to (...)” of the years 2010, 2011 and 2012 (Fomento de la producción, 2010-
2012) offer own resources data instead of the added value data of the firms.
The added values are not available for all the firms because, or there are enterprises that do
not provide some of the components for calculating their added value —SABI has not this problem
because it has full added value coverage—, or there are companies that belong a business group and
the added value is registered in the main firm —the Fomento de la producción dataset showed
results in the form of consolidated accounts—, or firms do not want to show negative added value
in their annual income statement —this is the case of the Fomento de la producción dataset but not
of the SABI dataset—, or there are subsidiary foreign firms deriving added value to their
headquarters. In previously table you can observe that on average the added value coverage of this
study is 54.9 percentage points over total. Obviously, complete coverage exchanges the results of
this study, and it requires that absolute results should be interpreted with caution. However, this
study may be useful to establish trends from the point of view of the evolutionary dynamic of the
economic activities of the largest non-financial Spanish firms. Following, relative added value and
employment calculations are necessary for modelling this study.
2.2. The description of the evolutionary model
This study uses a Rosling evolutionary model to analyze which Spanish economic activities
represented by the largest non-financial Spanish firms, measured by their operational revenue, had

higher added value and bigger employment from 1971 to 2012. The evolutionary model is an
annual 2D-plotted dispersion diagram. The dispersion diagram correlates two variables:
employment and added value. Employment is represented in the horizontal axis and added value in
the vertical axis. Both axis are segmented into two divisions. The first division includes the range
values from 0 to 0.5 and the second one from 0.5 to 1. So, this model presents four quadrants. The
bottom left quadrant indicates low added value and low employment economic activities, the
bottom right one low added value and high employment, the top left one high added value and low
employment, and the top right one high added value and high employment.

How to calculate which quadrant belongs to an «element»? Given quantity of employment of
an element in a year (EMPi), measured by number of people employed, and tangible added value of
the same element and year (ADDi), measured by real monetary values, of a sample of n elements;
then position of an element (xi,yi) in this 2D-plotted model is calculated as follows:

If an element is maximum employment and added value of the sample ( EMPi=max(EMPi)
and ADDi=max(ADDi) ), then position element is the upper right corner ( (xi,yi)=(1,1) ). If an
element is half of maximum employment and added value of the sample ( EMPi=max(EMPi)/2 and
ADDi=max(ADDi)/2 ), then position element is just located in the center ( (xi,yi)=(0.5,0.5) ). If an
element is maximum employment of the sample ( EMPi=max(EMPi) ) and half of maximum added
value of the sample ( ADDi=max(ADDi)/2 ), then position element is located in the right center
( (xi,yi)=(1,0.5) ). All possible combinations may be as following:
When an element equals zero added value ( yi=0 ) may means that, or there are no available
values for this element, or monetary added value is negative ( ADDi<0 ). An element can not be
zero employment quantity. I use the term «element» because the sample may be, or by economic
activities, or by economic sectors, or by individual firms, or by any other classification.

The elements of the dispersion diagram are plotted by bubbles. The bubble size is in
correspondence with the variable: operational revenue of the Income Statement or Profit and Loss
Account of an element, measured in nominal monetary value. In conclusion, the evolutionary model
is the result of the consecutive display of the annual dispersion diagrams from 1971 to 2012.
Importantly, both axis —employment and added value— are expressed in relative values to
the maximum value of the sample. So, inflation modifies bubble size because it is the only variable
expressed in absolute values —nominal operational revenue—. Like evolutionary model is plotted
by independent years inflation is not considered. Inflation modifies results when the whole period is
plotted in the same graphic, as follows:
Figure 3. Difference between real and nominal values in this model.
Source: Own made. Results of the model.
You may observe that element position is not altered by inflation because added value and
employment are relative values. The inflation modifies the size of the bubbles because operational
revenue is absolute value. If no annotation in the graphics is written, then by default it is understood
that monetary values are nominal —current prices—. To denote real values —constant prices— I
added in the graphic title: «(constant values)». Deflator used to calculate inflation is the «CPI» —
Consumer Price Index— of the National Institute of Statistics of Spain.21

2.3. Discussion
I have found eight points that they may be in discussion in this study.
a) According to Jorgenson, Ho & Stiroh,22 modeling of production processes must be respected
as much as possible the reality. Added value concept is an artificial construct considering only
primary inputs and, therefore, does not correspond to the output produced by a particular
industry. So, gross output is the correct way to reproduce the reality, and the added value so
does not.
b) If this study finished in the year 2006, then loss of homogeneity would not be in discussion.
As you can observe in the next figure, the SABI dataset supplement increases the added value
data because SABI database has full added value coverage. However, no economic activity
changes of quadrant.

The left graphic —2006— shows the results of the top 816 firms by operational revenue of
the mix between Fomento de la producción (2006) and SABI dataset, and 78.1 percentage
points of added value data coverage. The right one —2006*— is the same but without the
supplement of SABI dataset, ergo a sample size of 675 firms with added value data coverage
of 35.3 percentage points. Especially «big stores» is the recipient of SABI supplement as it
increases its value added.
However, in order to maintain a major homogeneity in this study, I did not want to prolong
the time period until 2013, despite the availability of SABI dataset for this year, because I did
not have any available data of the journal Fomento de la producción.
c) I decided to include firms without added value data in my database because the largest
Spanish firms is the study object and originality of this work. If full added value coverage
would has been the strategy, then, as companies were ranked by their operational revenue, this
study would not be about the economic activities of the largest Spanish firms. So, I preferred
to lose accuracy in the added value data with the purpose of maintaining operational revenue
and employment of the bigger Spanish enterprises. In the next figure you can note this effect.

The left graphic —2006*— shows the results of the top 675 firms by operational revenue of
Fomento de la producción (2006) without the supplement of SABI dataset. The right one —
2006**— is the same but with the firms without available added value data removed, ergo a
sample size of 238 firms with full data coverage. Differences are plausible. While
«telecom/Internet», «construction/real-estate», and «electric power» economic activities
maintain their same position in the quadrants; «big stores» and «various» economic activities
have changed of quadrant —from bottom right to bottom left—.
d) The size of the sample, obviously, changes the results. How many companies are included in
the concept «largest Spanish firms»? Top 50, top 500, top 1,000, the first 4,000, or perhaps the
first 8,000 Spanish enterprises. Representative sample size of the largest Spanish firms is
difficult to establish because economic activities positioning in the quadrants change. In the
next figure you can observe an example.

The left graphic shows the results of the top 664 firms by operational revenue of Fomento de
la producción (2002). The right one is the result of the upper quartile by operational revenue

economic activity remains unchanged; «construction/real-estate», «transports», «tourism»,
«food», «mechanical industry», «steel industry», «vehicles», and «computer» economic

activities increase in both employment and added value; «electric power» increases in
employment and decreases in added value; and, «telecom/Internet» and «petroleum» decrease
in both employment and added value.
e) Are largest Spanish firms of this study representative of the employment structure in Spain?
For answering this question is necessary to realize a little exercise.
According to the data of the Central Business Register of the National Institute of Statistics of
Spain,23 during the period 1999-2009, on average registered companies may be distributed in
four stretch. Spanish companies without employees were a 52.35 percentage points of the
registered companies in Spain during this period, firms between 1 and 49 employees were a
46.78 percentage points of the total, between 50 and 499 employees were a 0.82 percentage
points, and more of 500 employees were 0.05 percentage points.
According to the data of the Labor Force Survey of the National Institute of Statistics of
Spain,24 during the period 2008-2013, on average occupied population may be distributed in
three stretch. Self-employed were 17.15 percentage points of the occupied population in Spain
during this period, public employees were 16.93 percentage points, and private employees
were 65.91 percentage points.
For the common years —2008 and 2009— I proxy total private employees of the Labor Force
Survey between absolute number of firms with employees of the Central Business Register
assuming a uniform distribution and a constant number of employees for each stretch.
The average distribution of the private employees over total occupied population —65.91%—
between the three registered stretch of companies with employees in Spain in the years 2008
and 2009 were: 36.84 percentage points of the private employees work in a company between
1 and 49 employees, 17.08 percentage points in a firm between 50 and 499 employees, and
12.87 percentage points more of 500 employees.

f) CPI deflator is not the most appropriate indicator to measure the inflation effects in an
economy, the best one is the GDP deflator. The GDP deflator is a measure of the level of
prices of all new, domestically produced, final goods and services in an economy, while CPI
deflator only includes a representative basket of goods and services consumed by households.
However, for greater accuracy, deflator of each economic activity should be used since, for
example, the energy price index is not the same as the food price index because deflator is
used in this study for measuring the price effect in an economic activity during the whole
period.
g) The NACE 2009 primary code conversion of the SABI dataset —four digits— to the Fomento
de la producción economic activities may be in discussion. There are no automatic conversion
because a NACE may belong to different economic activities of Fomento de la producción.
So, a manual conversion would had been necessary.

producción may be in discussion. Obviously, any other economic activities classification
change the results. Firm economic activity classification was not fixed, and it might evolve
during the period 1971-2012. As next table shows, initially, there were twenty seven
economic activities in the year 1971: oils, various —tobacco and oil distribution25—,26 food,
beverages, rubber/tires, concrete, construction/real-estate, shipbuilding, mechanical industry,
25: The private leasing companies of national oil monopoly were classified by the authors of Fomento de la

electronic, electric power, pharma industries, electrical equipment, construction material, non-metallic
metallurgical, mining, paper, leather, plastics, milk products, chemical, refining
petroleum,27 utilities, steel industry, textile, vehicles, and glass.
In the year 1972 ten new economic activities were incorporated: commercial, wearing
apparel, publishers,28 big stores, tourism/hospitality, wood and furniture,29 insurance,
transports, holding,30 and advertising agencies.31
In the year 1982 five new economic activities appeared: commercial pharma, appliances,
computer, engineering, and perfumes/detergents; and one more the next year: commercial
vehicles.
The year 1999 authors of Fomento de la producción unified «electric power», «petroleum»,
and some firms of the «utilities» economic activities in the «energy» economic activity. I did
not follow this change because I wished to follow separately the path of this economic
activities. This year appeared a new economic activity: «telecommunications». It was the
aggregation of some firms of «utilities» and «electronic» economic activities. I followed it but
with changes. I aggregated only two electronic firms to «telecom» economic activity, the rest
of electronic firms did not be aggregated and remained in their economic activity.
Telecommunications firms removed from «utilities» economic activity caused that «utilities»
lost its previous role, for this reason I have jointly represented both economic activities in the
results.
27: The «refining petroleum» economic activity was renamed to «petroleum» in the year 1983.
28: The «publishers» economic activity was renamed to «publishing and arts graphics» in the year 1973, and
OVERCOMING THE CRISIS: ADDED VALUE EMPLOYMENT IN LARGEST SPANISH FIRMS

«mass media» in the year 1999.
29: The «wood and furniture» economic activity was renamed to «wood and cork» in the year 1999.
30: The «holding» economic activity appeared only two consecutive years in the journal Fomento de la
producción. The first year —1972— this economic activity included the National Institute of Industry —INI
—, a Spanish state-owned financing and industrial holding company. However, it did not include the broad
range of public national enterprises. The second year —1973— «holding» economic activity included the INI,
Rumasa and Ensidesa.
31: The «advertising agencies» economic activity appeared in the year 1972, and it did not come back to appear till
the year 1982.

3. Results
The expected results should must show a continuous path in correspondence with an
evolutionary model in constant adaption to its environment in the absence of radical changes —
technological revolutions—, incremental changes —products, services, processes, market or
organizational innovations—, or internal or external perturbations —political, economic,
sociological, cultural, artificial or natural—.

Notes: Employment and added value correlation is plotted by a lineal equation —y=mx+b— where y is the dependent
variable —added value—, m is the slope, x is the independent variable —employment—, and b is the Y-intercept.
Slope values were positive for all the years of the period 1971-2012, even though correlation
coefficient —r = √R2— of the sample resulted in regular adjustment because their annual values
ranged between 0.53 in the year 1986 —r = √0.28— and 0.83 in the year 1978 —r = √0.69—.33 All
slope values were superior to 0.5 with the exception of the years 1986, 1989 and 1991, and all Y-intercept
values were 0.0. Initially, slope value resulted in 0.56 in the year 1971, increased to 0.94 in
the year 1973, decreased to 0.41 in the year 1989, increased to 0.80 in the year 2002, decreased to

Appendix shows that, of a total of forty five activities, thirty two are in the bottom left
quadrant —low employment and low added value—: oils, food, beverages, rubber/tires, concretes,
commercial, wearing apparel, shipbuilding, publishers/mass media, electronic, financial,
tourism/hospitality, pharma industry, wood and furniture, construction material, non-metallic
metallurgical, mining, paper/board, leather, plastics, milk products, insurance, textile, glass,
holding, advertising agencies, commercial pharma, appliances, computer, engineering,
perfumes/detergents, and commercial vehicles; and, thirteen sectors are outside this quadrant.
Now is time to analyze these outsiders.
3.3. The ««microresults»» of the outsiders
For all graphs in this section, the left graphics show the results of a single economic activity
throughout the whole period in the evolutionary model in constant values, and the right graphics
show the annual quadrant positioning of employment and value added of this economic activity
with their respective lineal trends. If employment and added value positioning data are lower than
0.5, then economic activity is inside the bottom left quadrant —low employment and low added
value—. If employment positioning data is higher than 0.5 and added value positioning data is
lower than 0.5, then economic activity is inside the bottom right quadrant —high employment and
low added value—. If employment positioning data is lower than 0.5 and added value positioning
data is higher than 0.5, then economic activity is inside the top left quadrant —low employment and
low added value—. If employment and added value positioning data are higher than 0.5, then
economic activity is inside the top right quadrant —high employment and high added value—.
Remember that all graphs do not show values for 1987 and 1988 due to the absence of added

1994, when it showed a U-shaped during the period 1994-2012, with the exception of the years
2002 and 2012 when it came back to be maximum added value. It was never maximum
employment of the sample. It showed a «regression» employment lineal trend during the whole
period, and a «regression» added value one from 1990 to 2012. Employment trend evolved from 0.4
points respect to maximum value of the sample in 1971 to under 0.2 points in 2012, and added
value trend evolved from 1 points to under 0.7 points. A «parallelism» relationship between
employment and added value might be inferred.

This is the evolution of the annual top 10 economic activities during the period 1971-2012.
This ranking tries to measure the wealth generating of the largest Spanish firms sorted by economic
activities during this period. It —wealth ranking ri— is got with the sum of employment quadrant
positioning —xi— and added value quadrant positioning —yi— resulted of the evolutionary model
—ranking ri=xi+yi, where i is an economic activity—. The next figure shows the results:34

Electric power was top one in the year 1971, and it was an economic activity inside the top
left quadrant —low employment and high added value—; transports was top one in the year 1972, it
was ranked in the 36th position in the previous year, and it was an economic activity inside the top
right quadrant —high employment and high added value—; and, construction and real-estate was
top one in the period 1973-1977, and it was an economic activity inside the top right quadrant.
The electric power economic activity evolved from the first position in the year 1971, to third
position in the period 1972-1974, to second position in the year 1975, and fourth position in the
year 1976.

The previous top left figure shows economic activities distribution of the period 1971-2012. A
bubble concentration in the bottom left quadrant is evident. Of a total of 1,617 economic activities
registered in this study in the whole period, 85.5 percentage points were plotted in the bottom left
quadrant —low employment and low added value—, 6.4 percentage points were plotted in the
bottom right one —high employment and low added value—, 4.7 percentage points in the top right

one —high employment and high added value—, and 3.4 in the top left one —low employment and
high added value—. So, an absolute majority of the bottom left quadrant was registered.
The previous top right figure shows operational revenues distribution: 62.5 percentage points
were plotted in the bottom left quadrant —low employment and low added value—, 14.2
percentage points were plotted in the top right one —high employment and high added value—,
13.7 percentage points in the bottom right one —high employment and low added value—, and 9.5
in the top left one —low employment and high added value—. So, an absolute majority of the
bottom left quadrant was registered.
The previous bottom left figure shows employment distribution: 52.1 percentage points were
plotted in the bottom left quadrant —low employment and low added value—, 23.9 percentage
points were plotted in the bottom right one —high employment and low added value—, 19.6
percentage points in the top right one —high employment and high added value—, and 4.4 in the
top left one —low employment and high added value—. So, again an absolute majority of the
bottom left quadrant was registered.
The previous bottom right figure shows added value distribution: 44.3 percentage points were
plotted in the bottom left quadrant —low employment and low added value—, 25.8 percentage
points were plotted in the top right one —high employment and high added value—, 16.9
percentage points in the top left one —low employment and high added value—, and 12.9 in the
bottom right one —high employment and low added value—. So, a simple majority of the bottom
left quadrant was registered.
The bottom left quadrant is top one by total economic activities, by total operational revenues,
by total employment, and by total added value. The bottom right quadrant is second position by
total economic activities, third by total operational revenues, second by total employment, and last
by total added value. The top left quadrant is last —fourth— position by total economic activities,
by total operational revenues, and by total employment; but third by total added value. The top right
quadrant is third position by total economic activities, second by total operational revenues, third by
total employment, and second by total added value.

Correlation between employment and added value in the aggregated model was plotted with a
rational function.35 Trendline started in the bottom left corner —(x,y)=(0,0)— and finished in the
top right quadrant —(x,y)=(1,0.72)— through the bottom right quadrant. This correlation resulted in
bad adjustment because correlation coefficient was less than 0.5 —r = √0.20—.
Next figure shows operational revenue, employment, added value and apparent productivity
evolution of the four quadrants during the whole period. It is important to note that operational
revenue, employment and added value are measured in percentage points respect to the total sample
values. It is not in respect to the maximum sample value as in the evolutionary model. Apparent
productivity is calculated by the relation between added value percentage points and employment
percentage points.

4. Answer to questions
The main question of this study is: Which Spanish economic activities had high employment
and high added value in the largest Spanish firms during the period 1971-2012?
The answer to this question is those economic activities showed in the bottom right quadrant
in the evolutionary model in some year of the period 1971-2012. The chronological results show
that: steel industry appeared in the bottom right quadrant in 1971, 1972, 1974-1976, 1978, and
1979; transports in 1972, 1973, 1978 and 1982; vehicles one in 1973, 1976-1983 and 1990;
construction and real-estate in 1973-1980, 2001-2004 and 2006-2009; electrical equipment only in
the year 1977; utilities from 1979 to 1998 —remember that years 1987 and 1988 are not available
in this study because added value was in absence in the original data source—; telecom and Internet
continued the way left by utilities from 1999 to 2012; big stores in 2002 and 2010-2012; and,
finally, various in the years 2011 and 2012.
Six economic activities were showed in the top left quadrant —low employment and high
added value—: electric power appeared the whole period in this quadrant with the exception of the
year 2005; utilities in 1972 and 1976-1978; steel industry only in the year 1973; chemical in 1974
and 1976; petroleum in 1993-1994, 1996, 2000-2002 and 2010; and, finally, vehicles in the years
1996 and 1997.
Eight economic activities were showed in the bottom right quadrant —high employment and
low added value—: construction and real-estate in 1971-1972, 1981-2000, 2005 and 2010-2012;
electrical equipment in 1971, 1974-1976 and 1979-1980; vehicles in 1971, 1974-1975, 1984-1989
and 1991-1994; transports in 1974-1977, 1979-1981, 1983-1996 and 2000-2001; mechanical
industry from 1974 to 1977; steel industry in 1977 and from 1980 to 1985; various in 1980-1981
and 2004-2010; and, finally, big stores from 1985 to 2009 with the exception of the year 2002.
Thirty two economic activities were always in the bottom left quadrant —low employment
and low added value—: oils, food, beverages, rubber and tires, concretes, commercial, wearing
apparel, shipbuilding, publishers and mass media, electronic, financial, tourism and hospitality,
pharma industry, wood and furniture, construction material, non-metallic metallurgical, mining,
paper and board, leather, plastics, milk products, insurance, textile, glass, holding, advertising

agencies, commercial pharma, appliances, computer, engineering, perfumes and detergents, and
commercial vehicles.
Summarizing, as next figure shows, according to the results of the evolutionary model, nine
Spanish economic activities of a total of forty five had high employment and high employment —
top right quadrant— during the period 1971-2012: steel industry, transports, vehicles, construction
and real-estate, electrical equipment, utilities, telecom and Internet, big stores, and various. There
were thirteen «outsiders» —economic activities outside the bottom left quadrant—: those nine ones
of the top right quadrant; and, electric power, chemical, and petroleum in the top left quadrant; and
mechanical industry in the bottom right quadrant. So, largest quadrant was the bottom left, followed
by the top right, after the top left, and finally the bottom right.

The first secondary question of this study is: What was the evolutionary dynamic of these

JESPERGON
economic activities?
According to the «microresults», five basic evolutionary patterns were possible to
differentiate in these outsiders —economic activities outside the bottom left quadrant—:
«continuous path», «cumulus», «discontinuous path», «mutation», and «chaos». All these patterns
may be combined among them with a total of twenty possible combinations. The «continuous path»
pattern is a sequence data without ups and downs, and it was showed by electric power, chemical,
mechanical industry, electric equipment, steel industry, vehicles, big stores, and utilities and
telecom/Internet economic activities. The «cumulus» pattern is an independent accumulation data,
and it was showed by petroleum, mechanical industry, electrical equipment, big stores, and utilites
and telecom/Internet ones. The «discontinuous path» pattern is a sequence data with ups and downs,
and it was showed by transports, and construction and real-estate ones. The «mutation» pattern is an
isolate data, and it was showed by petroleum, and utilites and telecom/Internet ones. The «chaos»
pattern is a discontinuous data, and it was showed by various and vehicles ones. Relationship
between evolutionary patterns and, employment and added value results, was not found.
Summarizing, as next figure shows, of a total of thirteen economic activities, two economic
activities showed a «chaos» basic evolutionary pattern —one in combination with the «continuous
path»—, nine ones showed a «continuous path», six a «cumulus» —five of them in combination
with the «continuous path» and one in combination with the «mutation»—, three a «mutation» —
two in combination with the «cumulus and continuous path» and other in combination with the
«cumulus»—, and two a «discontinuous path». So, largest basic evolutionary pattern was the
«continuous path», and largest blend evolutionary blend was the «cumulus and continuous path».
