Most of welfare economics studies focus on the relation between utility and quantities of consumption goods. Our micro-economic approach is not common as we do not only focus on a quantitative analysis, we include the social dimension which is qualitative. The aim of this paper is to study the impact of an income increase on welfare. It focuses on the evaluation of the individual well-being : not too happy, pretty happy, very happy. This paper also shows how the welfare of a person is likely to change to an income increase depending on her social characteristics (age, gender, religion...), we focused on some of them : marital status, labor force status and education. Increasing income leads to a better life evaluation until the income reached approximately 87,000$. Throughout, in order to provide rigorous results, as the outcome is an ordered categorical variable we used an ordered logistic regression model.
This paper uses Chinese micro survey data to construct a sort selection model. By considering the income level and urban-rural differences, the heterogeneous relationship and influence mechanism between income structure and happiness are systematically studied, and the results of the study pass the test of robustness. The empirical results show that the coverage of operating income is wider, the impact on the happiness of low and middle income families is more significant, and the income of business income and happiness is "U" type; wage income is only certain for the happiness of middle-income families. The significant influence, the relationship shows a "U" type; the transfer income is more likely to affect high-income families, and the relationship between income and happiness is inverted "U" type; property income is not statistically significant under the above circumstances. The policy meaning of this paper is: to improve the happiness of residents, starting from the income level and income structure, focusing on improving the family's operating income and property income.

This document analyzes the challenges of using policy to increase happiness. It discusses how happiness is difficult to define and measure. While income increases happiness to a point, beyond $50,000 it has little effect. Other factors like relationships and work satisfaction seem more influential. Measuring happiness with simple surveys is problematic as people cannot accurately assess what affects their well-being. Policymakers risk focusing on the wrong issues due to these measurement challenges and misunderstandings about what causes happiness. Overall, while considering happiness is reasonable, it should not be the sole policy goal due to these difficulties in defining, measuring, and understanding what drives human happiness.
This paper explores the relationship between subjective well-being and income for Belgian inhabitants. The impact of income on subjective well-being is analyzed as well as the existence of a satiation point.
This document analyzes socioeconomic inequalities in wellbeing in Costa Rica. It finds that higher income and education are associated with greater wellbeing, while unemployment, female gender, and divorced/separated status are linked to lower wellbeing. Health status also influences wellbeing and contributes to inequalities, with wealthier groups reporting better health. The study uses an ordered logit model and concentration index to examine relationships between various determinants and wellbeing measures from a national survey. It concludes that while Costa Ricans with higher incomes have greater wellbeing, the distribution of wellbeing is more equal than income, and health inequalities most negatively impact younger age groups.
Child-related transfers: is there a room for welfare improvement?GRAPE
How does income risk affect the optimal size of the child-related transfer system? I answer this question in an overlapping generations model with endogenous fertility and PAYG social security. I show that the optimal size of the child-related transfer is increasing in income risk.
First, in the stylized model, I provide the intuition behind this result. Second, I quantify the size of welfare gains due to child-related transfer reform in a full-fledged model calibrated to the US economy.
Expansion of child-related transfer yields to welfare gain even with constant income dispersion. In a scenario with higher income dispersion, welfare gains increase from 1.08% to 1.2% of lifetime consumption.
Third, I show that in a scenario with high-income dispersion, even higher welfare gains may be obtained if the child-related transfer system has a more redistributive nature.

Statistical discrimination at young age due to fertility expectations may decrease as the average age of first birth increases. The authors analyze data from 56 countries over four decades to test whether changes in the timing of fertility are linked to changes in adjusted gender wage gaps for labor market entrants aged 20-30. They estimate adjusted gender wage gaps and instrument for fertility timing using reforms to compulsory education, military conscription policies, and the authorization of contraceptive pills across countries over time.
This document discusses the Second Demographic Transition (SDT) theory of fertility developed by Ron Lesthaeghe between 1986-2009. It presents evidence that while postponement of births is occurring across countries, the extent to which fertility declines at younger ages are made up at older ages (known as "recuperation") varies significantly between countries. Regression analysis shows that factors for postponement and recuperation explain 79.3% of the variation in fertility rates, more than models only considering baseline cohort fertility or postponement. Therefore, differential recuperation is an important determinant of period fertility rates in addition to postponement effects.

-understand the qualitative measurement of happiness
This document provides an overview and critical analysis of Richard Layard's 2005 book "Happiness: Lessons from a New Science". The summary discusses:
1) Layard uses psychological and economic research to argue that increasing income does not necessarily increase happiness and has unintended consequences like worsening mental health.
2) Layard recommends policies like reducing unemployment, changing the nature of work to improve work-life balance, and monitoring trends in well-being in addition to GDP.
3) Critics argue these policies give the government too much power over private lives and that happiness is too subjective. However, happiness economics aims to inform rather than control choices.
The Easterlin Paradox challenges the idea that economic growth alone leads to increased happiness. While cross-sectional data shows richer individuals and countries report higher life satisfaction, longitudinal data shows life satisfaction does not increase as GDP per capita rises over time. Two key studies provide evidence for this: data from 54 countries over 28 years and the Gallup World Poll of countries over 14 years both show no significant relationship between GDP growth rates and increases in life satisfaction. Explanations for the paradox include hedonic adaptation and social comparisons that reduce the happiness impact of rising incomes. The Easterlin Paradox presents a challenge to the view that pursuing economic growth is sufficient to improve well-being.

This study uses administrative data on Swedish lottery players to estimate the causal impact of wealth on health outcomes. The data allows for a large sample size with little attrition. Three lottery samples are pooled to examine the effect of wealth on players' health and their children's health and development. In the adult analyses, the researchers find no significant effects of wealth on mortality or health care utilization, with a possible small reduction in mental health drug use. In the intergenerational analyses, wealth increases children's health care utilization after the lottery and may reduce obesity risk, but other child outcomes are not significantly affected. Overall, the findings provide little evidence that wealth causally impacts health.

Money Doesn’t Buy Happiness. Well, on Second Thought . . .If mon.docxmoirarandell
Money Doesn’t Buy Happiness. Well, on Second Thought . . .
If money can’t buy you love, can it still buy you happiness? A now famous 1974 study seemed to indicate that the answer was no. U.S. economist Richard Easterling, then at the University of Pennsylvania, studied comparative data on moderately wealthy and very wealthy countries and concluded that although rich people are happier than poorer people, rich countries are not happier than poorer ones, and they do not grow happier as they grow increasingly rich. The explanation for this apparent paradox, said Easterlin, was that only relative income—your income compared to that of your peers and neighbors—matters to happiness, not absolute income. Now, however, two Wharton professors, Betsey Stevenson and Justin Wolfers, say that the Easterlin paradox, as it has came to be called, does not exist. Based on new research, they say that the truth isn’t paradoxical at all, but is in fact very simple: “1. Rich people are happier than poor people. 2. Richer countries are happier than poorer countries. 3. As countries get richer, they tend to get happier.” Pointing out that 35 years ago Easterlin had little data to work with, Stevenson and Wolfers draw their conclusions from data about more countries, including poor ones, over longer periods of time. Public opinion surveys and other studies show that life satisfaction is highest in richer countries. In the United States, for instance, 9 in 10 Gallup Survey respondents in households making more than $250,000 a year called themselves “very happy,” compared to only 4 in 10 with incomes below $30,000. “On balance,” Stevenson and Wolfers conclude, “GDP and happiness have tended to move together.” The bottom line, they say, is that absolute income matters. What do these new findings mean in practice? A pair of British economists suggest that government’s policy goals should focus less on growing GDP and more on improving measures that directly affect happiness. Easterlin would probably agree. He now concedes that people in wealthy countries do report more happiness than those in poorer countries. But he still doubts that money alone is the reason. Comparing Denmark and Zimbabwe, for instance, he says, “The Danes have social welfare policies directed toward some of the most salient concerns of families—their health, care for the aged, child care. If you ask why the Danes are happier, an alternative hypothesis is they have a set of public policies that deal more immediately with people’s fundamental concerns.” In addition, the tiny Himalayan kingdom of Bhutan has, in fact, replaced GDP with a measure it calls “gross national happiness.”
Critical Thinking Questions
1. What do you think is the role of money as a determinant of a person’s satisfaction at work and with life in general? Should organizations worry about this issue? Explain.
2. As discussed in this chapter, firms vary widely on the extent to which they emphasize money as an incentive. Do you t ...
The document discusses using anchoring vignette surveys to measure subjective well-being or happiness in a way that accounts for biases. It proposes using vignettes that describe people in different life situations on a scale to determine how factors like family, marriage, and wealth impact happiness. Respondents would rate how happy the people in the vignettes seem. This would allow researchers to calculate elasticities for how changes in factors influence happiness and develop a happiness function to estimate real happiness levels. The results could help prioritize policies and programs to maximize subjective well-being.
The paper examines how economic vulnerability and insecurity impact physical and mental health using data from the Household, Income and Labour Dynamics in Australia Survey. It finds that while the effect of insecurity on health is the same across income classes, the total effect is larger for the poor since they experience more insecurity. The key results are that mental health is more strongly impacted by insecurity than physical health, and reducing the incidence of insecurity could particularly benefit those with low incomes.
This document analyzes whether there is evidence that higher income is no longer associated with higher subjective well-being (life satisfaction or happiness) once basic needs have been met. The authors test this "modified Easterlin hypothesis" using multiple datasets on well-being and income across countries and within countries. They find:
1) Across countries, subjective well-being is highly correlated with GDP per capita and the relationship remains linear even at high income levels, providing no evidence of a satiation point.
2) Regressions testing whether the well-being-income relationship differs below and above various income thresholds find similar gradients, providing no statistical support for a satiation point.
3) Non-parametric fits of the
This paper examines the effect of ability, as measured by IQ, on individual wages while controlling for other factors. The authors analyze data from the National Longitudinal Survey of 1976 on over 5,000 individuals. Their statistical model finds that higher IQ has a small but statistically significant effect on higher wages. Education level and living in an urban area have larger effects on wages. Unexpectedly, the model shows higher parental education lowers wages and availability of newspapers/magazines does not affect wages. The authors note limitations around incomplete education data and issues with the parental education ranking variable. They conclude that while IQ impacts wages, other social and educational factors have relatively stronger influences.

1) Relative income position has only weak to moderate effects on various well-being outcomes like health, mental health, and life satisfaction. These effects are further reduced when other factors like demographics, material conditions, and social stratification are considered.
2) Material conditions have a stronger influence on well-being than relative income position across most outcomes. Supporting the importance of absolute living standards over relative income position.
3) Reducing income inequality should not be the sole policy focus according to these results. Greatest improvements to well-being would come from reducing poverty and improving material living standards for all. Policy needs a broader perspective than just income inequality.

Money Doesn’t Buy Happiness. Well, on Second Thought . . .
If money can’t buy you love, can it still buy you happiness? A now famous 1974 study seemed to indicate that the answer was no. U.S. economist Richard Easterling, then at the University of Pennsylvania, studied comparative data on moderately wealthy and very wealthy countries and concluded that although rich people are happier than poorer people, rich countries are not happier than poorer ones, and they do not grow happier as they grow increasingly rich. The explanation for this apparent paradox, said Easterlin, was that only relative income—your income compared to that of your peers and neighbors—matters to happiness, not absolute income. Now, however, two Wharton professors, Betsey Stevenson and Justin Wolfers, say that the Easterlin paradox, as it has came to be called, does not exist. Based on new research, they say that the truth isn’t paradoxical at all, but is in fact very simple: “1. Rich people are happier than poor people. 2. Richer countries are happier than poorer countries. 3. As countries get richer, they tend to get happier.” Pointing out that 35 years ago Easterlin had little data to work with, Stevenson and Wolfers draw their conclusions from data about more countries, including poor ones, over longer periods of time. Public opinion surveys and other studies show that life satisfaction is highest in richer countries. In the United States, for instance, 9 in 10 Gallup Survey respondents in households making more than $250,000 a year called themselves “very happy,” compared to only 4 in 10 with incomes below $30,000. “On balance,” Stevenson and Wolfers conclude, “GDP and happiness have tended to move together.” The bottom line, they say, is that absolute income matters. What do these new findings mean in practice? A pair of British economists suggest that government’s policy goals should focus less on growing GDP and more on improving measures that directly affect happiness. Easterlin would probably agree. He now concedes that people in wealthy countries do report more happiness than those in poorer countries. But he still doubts that money alone is the reason. Comparing Denmark and Zimbabwe, for instance, he says, “The Danes have social welfare policies directed toward some of the most salient concerns of families—their health, care for the aged, child care. If you ask why the Danes are happier, an alternative hypothesis is they have a set of public policies that deal more immediately with people’s fundamental concerns.” In addition, the tiny Himalayan kingdom of Bhutan has, in fact, replaced GDP with a measure it calls “gross national happiness.”
Critical Thinking Questions
1. What do you think is the role of money as a determinant of a person’s satisfaction at work and with life in general? Should organizations worry about this issue? Explain.
2. As discussed in this chapter, firms vary widely on the extent to which they emphasize money as an incentive. Do you t ...
The document discusses using anchoring vignette surveys to measure subjective well-being or happiness in a way that accounts for biases. It proposes using vignettes that describe people in different life situations on a scale to determine how factors like family, marriage, and wealth impact happiness. Respondents would rate how happy the people in the vignettes seem. This would allow researchers to calculate elasticities for how changes in factors influence happiness and develop a happiness function to estimate real happiness levels. The results could help prioritize policies and programs to maximize subjective well-being.
The paper examines how economic vulnerability and insecurity impact physical and mental health using data from the Household, Income and Labour Dynamics in Australia Survey. It finds that while the effect of insecurity on health is the same across income classes, the total effect is larger for the poor since they experience more insecurity. The key results are that mental health is more strongly impacted by insecurity than physical health, and reducing the incidence of insecurity could particularly benefit those with low incomes.
This document analyzes whether there is evidence that higher income is no longer associated with higher subjective well-being (life satisfaction or happiness) once basic needs have been met. The authors test this "modified Easterlin hypothesis" using multiple datasets on well-being and income across countries and within countries. They find:
1) Across countries, subjective well-being is highly correlated with GDP per capita and the relationship remains linear even at high income levels, providing no evidence of a satiation point.
2) Regressions testing whether the well-being-income relationship differs below and above various income thresholds find similar gradients, providing no statistical support for a satiation point.
3) Non-parametric fits of the
This paper examines the effect of ability, as measured by IQ, on individual wages while controlling for other factors. The authors analyze data from the National Longitudinal Survey of 1976 on over 5,000 individuals. Their statistical model finds that higher IQ has a small but statistically significant effect on higher wages. Education level and living in an urban area have larger effects on wages. Unexpectedly, the model shows higher parental education lowers wages and availability of newspapers/magazines does not affect wages. The authors note limitations around incomplete education data and issues with the parental education ranking variable. They conclude that while IQ impacts wages, other social and educational factors have relatively stronger influences.

1) Relative income position has only weak to moderate effects on various well-being outcomes like health, mental health, and life satisfaction. These effects are further reduced when other factors like demographics, material conditions, and social stratification are considered.
2) Material conditions have a stronger influence on well-being than relative income position across most outcomes. Supporting the importance of absolute living standards over relative income position.
3) Reducing income inequality should not be the sole policy focus according to these results. Greatest improvements to well-being would come from reducing poverty and improving material living standards for all. Policy needs a broader perspective than just income inequality.

"Does Foreign Direct Investment Negatively Affect Preservation of Culture in the Global South? Case Studies in Thailand and Cambodia."
Do elements of globalization, such as Foreign Direct Investment (FDI), negatively affect the ability of countries in the Global South to preserve their culture? This research aims to answer this question by employing a cross-sectional comparative case study analysis utilizing methods of difference. Thailand and Cambodia are compared as they are in the same region and have a similar culture. The metric of difference between Thailand and Cambodia is their ability to preserve their culture. This ability is operationalized by their respective attitudes towards FDI; Thailand imposes stringent regulations and limitations on FDI while Cambodia does not hesitate to accept most FDI and imposes fewer limitations. The evidence from this study suggests that FDI from globally influential countries with high gross domestic products (GDPs) (e.g. China, U.S.) challenges the ability of countries with lower GDPs (e.g. Cambodia) to protect their culture. Furthermore, the ability, or lack thereof, of the receiving countries to protect their culture is amplified by the existence and implementation of restrictive FDI policies imposed by their governments.
My study abroad in Bali, Indonesia, inspired this research topic as I noticed how globalization is changing the culture of its people. I learned their language and way of life which helped me understand the beauty and importance of cultural preservation. I believe we could all benefit from learning new perspectives as they could help us ideate solutions to contemporary issues and empathize with others.

Impact of the income on happiness
according to the social context
Abstract
Most of welfare economics studies focus on the relation between utility and quantities
of consumption goods. Our micro-economic approach is not common as we do not only
focus on a quantitative analysis, we include the social dimension which is qualitative. The
aim of this paper is to study the impact of an income increase on welfare. It focuses on the
evaluation of the individual well-being : not too happy, pretty happy, very happy. This
paper also shows how the welfare of a person is likely to change to an income increase
depending on her social characteristics (age, gender, religion, etc.), we focused on some
of them : marital status, labor force status and education. Increasing income leads to
a better life evaluation until the income reached approximately $87,000. Throughout, in
order to provide rigorous results, as the outcome is an ordered categorical variable we used
an ordered logistic regression model.

3. 1 Introduction
Money is what governs our interactions daily, it allows us to buy consumption goods. The most
common way to earn money is to have an income. Income increases the welfare of an individual
in a certain measure, just make yourself the following thought experiment : if you do not have
money, you will not be able to buy some foods, to live in your own apartment etc.; hence you
will be hungry and get cold, as a consequence you will be less happy compared to the situation
in which you have an income. Increasing the social welfare is a relevant goal, everybody wants
to be happy. Furthermore, this aim is also written in the Declaration of the Rights of Man and
of Citizens (1793), article n◦
1 (translation) : "The aim of society is the common welfare".
We first want to check if an increase of income enhances welfare or not and we will analyze
precisely this impact. Then we will measure this impact following the social context. So the
problematic is the following : what is the impact of an income increase on welfare ? Does the
social context affects this increase ? By "social context" we mean all the social interactions
the individual can have, what social characteristics does he have : number of children, marital
status, education, etc.
We can consider for instance the case of a poor person and a wealthy one (the others
characteristics are equal for both), does an increase of income impact the same way the welfare
of those individuals ? We can ask ourselves several questions1
: does the impact of an income
increase on welfare is the same between a married person and an single one ? Is it the same
between a man and a woman ? Does an income increase has the same effect on welfare between
a person who is graduated and a person who is low educated ? These questions will be covered
in the section dedicated to the results.

For the following questions we assume that all the characteristics between the individuals are the same,
except for the characteristic to be analyzed, obviously.

4. 2 Literature review
The two Nobel laureates in economics: Daniel Kahneman and Angus Deaton (2010) have
worked on the relation between high income and differences with the life evaluation and the
emotional well being. It has been found that high earners have better life satisfaction, however
people’s day-to-day emotional well-being increases until an annual income threshold of $75,000.
This suggests that welfare takes into account the income and suggests as well there exists a
limit above which increasing income has no more effect on happiness.
Concerning the unemployment, Winkelmann (1998) found no evidence of the impact of
unemployment on well-being, contrary to Gielen and Van Ours (2012) who has found that when
workers become unemployed their happiness drops substantially. We expect that people without
a job can be less happy than people who works, depending on their social characteristics2
.
Powdthavee, Lekfuangfu and Wooden (2013) analyzed the effect of education on happiness,
they found there is an effect of an extra year of education on income, and also an effect of income
on subjective well-being, but they did not find the evidence of an extra year of education on life
satisfaction and advice future researchers to use the degree quality. We expect that there is a
link between degree and happiness and we suggest that the degree quality is a more appropriate
approach than the number of years of education.
Morevover, Chris M. Herbst and John Ifcher (2016) found that parents are happier over time
relative to non-parents in contradiction with Luca Stanca (2012) who has found that having
children is negatively related to well-being. This disagreement can be explain by the age of the
parents and also the family income.
Throughout this paper, we will compare our results with those of the authors presented in
this section.

5. 3 Data description
3.1 Source
The data used in this empirical project was produced by the General Social Survey3
. After
transformation (cf. Appendices, Table 11), we used cross-section data on 2506 observations
from residents of United States. The survey was conducted on adults from 18 to 89 years and
in agreement with the analysis we want to conduct we chose specific variables (cf. Table 1).
3.2 Summary statistics
The dependent variable is called welfare, with levels “Not too happy” (welfare = 0), “Pretty
happy” (welfare = 1), and “Very happy” (welfare = 2)4
. Most observations (57.06%) are
"Pretty happy", 28.45% claims to be "Very happy" and the least represented population feels
"Not too happy" (14.49%) (cf. Table 2).
Descriptive statistics from the quantitative variables inform us that, the mean of inc, which
represents the annual income, is around $33,112, the average person is 49 years old and the
number of children (child) is around 2 in average (cf. Table 4). If we look at the average of
these variables by level of happiness (cf. Table 5) we can see that the average income increases
according to the level of happiness (from $18,238 for "Not too happy" to $40,574 for "Very
happy") contrary to average number of children which decreases from 2.11 to 1.86. Concerning
the age (age) it does not seem to be any real difference.
Moreover we chose six qualitative variables (cf. Table 3), and as we can see (cf. Table 6)
the dataset contains a large proportion of religious people (relig = 1), 77% of the observations
are religious and 62% have a job (work = 1). Nonetheless high educated people (educ = 1)
and non-white people (nonwhite = 1) are under-represented with 31% and 26% respectively.

4
(cf. Table 1)
5
6. Finally what is interesting to analyze is the average of dummy variables by level of happiness
(cf. Table 7). This table suggests that the mean of nonwhite is decreasing with happiness from
32% to 24% contrary to the average of married which is increasing from 19% to 58%. Moreover
the representation of educ, work and married, seems to be higher for people who are happy5
.
4 Econometric specification
In our analysis, the dependent variable (welfare) is a categorical variable which can takes three
different values (cf. Table 1), as the outcome is ordered and can take more than two values, an
appropriate estimation method is the ordered logit regression model6
.
The welfare of an individual depends on the income and the other control variables we
include in our model 7
. So the relation is the following :
welfare∗
= incβ1 +ageβ2 +femaleβ3 +religβ4 +marriedβ5 +educβ6 +workβ7 +childβ8+
nonwhiteβ9 + u (M1)
We assume the error term u follows a standard logistic distribution8
. Note that it is written
welfare∗
instead of welfare. welfare∗
is a latent variable that we cannot observe directly but
in order to compute the probability of being "Not too happy", "Pretty happy" or "Very happy"
we have to use the latent variable and two cut points (or threshold parameters) : α1 and α2
9
.
welfare = 0 if welfare∗
≤ α1
welfare = 1 if α1 < welfare∗
≤ α2
welfare = 2 if welfare∗
> α2
5
E.g., among those who stated to be "Very happy", 38% were high-educated, 58% were married, 65% were
working, these percentages are lower for people who stated to be "Not too happy" or "Pretty happy".
6
A multinomial logit regression model could have been used but this latter does not take into account that
the outcome is ordered, as a consequence the ordered logit regression model is more appropriate in this case as
an individual is happier when he answers he is "Very happy" rather than "Pretty happy", and he is obviously
happier when he answers he is "Pretty happy" rather than "Not too happy"
7
(cf. Table 1)
8
u is a continuously distributed variable independent of X and the distribution of u is symmetric about zero.
9
α1 and α2 are estimated by maximum likelihood (cf. Appendices, Maximum Likelihood).
6
7. We denote all the control variables by X and the corresponding parameters by β so the
latent variable can be written as : welfare∗
= Xβ + u.
E.g. the probability of being "Not too happy" can be computed as followed using the logit
function10
:
P[welfare = 0|X] = P[welfare∗
≤ α1|X] = P[u ≤ α1 − Xβ|x] = Λ(α1 − Xβ)
The probability of being pretty happy and very happy are computed the same way and here
are the corresponding formulas :
P[welfare = 1|X] = Λ(α2 − Xβ) − Λ(α1 − Xβ)
P[welfare = 2|X] = Λ(Xβ − α2)
As written in the literature review section, Kahneman and Deaton (2010) have found that
people are no longer happier above an annual income of 75,000$, so we expect some non-linearity
(like a concave function) caused by the corresponding variable inc, adding this variable to the
square in the regression model is a solution to see if there is any value of inc after which the
probability of being "Very happy" no longer increases. For this reason we added a second model
in our analysis :
welfare∗
= incζ1 + inc2
ζ2 + femaleζ3 + nonwhiteζ4 + ageζ5 + educζ6 + workζ7 + childζ8+
marriedζ9 + religζ10 + (M2)
For (M2) we denote all the control variables by X and the corresponding parameters by ζ
so the latent variable can be written as : welfare∗
= Xζ +
We assume the error term follows a standard logistic distribution11
.
The probabilities are computed the same way :
P[welfare = 0|X] = Λ(α1 − Xζ)
10
Λ(.) is the logit function : Λ(z) =
ez
1 + ez
11
is a continuously distributed variable independent of X and the distribution of is symmetric about zero.
7
8. P[welfare = 1|X] = Λ(α2 − Xζ) − Λ(α1 − Xζ)
P[welfare = 2|X] = Λ(Xζ − α2)
5 Empirical results
5.1 Impact of the income on happiness
5.1.1 First approach
Does an income increase have an impact on happiness ? From (M1)12
, the estimated threshold
parameters (”α1, ”α2) are significant at the 1% level. β1 = 0.06 is positive and significant at the
1% level, so we expect inc to have a positive impact on the probability of being "Very happy"
and a negative impact on the probability of being "Not too happy", the effect on the probability
of being "Pretty happy" is more ambiguous13
. However the value of the coefficient estimate
is not interpretable, we cannot tell, as in an Ordinary Least Square (OLS) regression: ceteris
paribus, the effect of the increase of one unit of inc on the predicted response probabilities is
just the coefficient estimate associated to inc because in our case, the derivative of the response
probabilities of welfare = j|X, j ∈ {0, 1, 2} with respect to an explanatory variable takes into
account the value taken by all the explanatory variables.
In order to know the partial effect of a variable on welfare = j |X, j ∈ {0, 1, 2}, marginal
effects have to be computed. To provide representative results, marginal effects will be com-
puted at the average point14
: this particular "individual" is a low educated white woman of
49 years old who works and has 2 children, she earns $33,112 per year, she is religious and
single. At the average point, ceteris paribus, the partial effect of an increase of inc of one unit
12
cf. Table 8
13
cf. Appendices to see the formulas of the marginal effects, the sign of βk determines the sign of the marginal
effects on the probability of being "Not too happy" (welfare = 0) and on the probability of being "Very happy"
(welfare = 2). The effect on the probability of being "Pretty happy" (welfare = 1) is determined by the sign
of λ(α1 − Xβ) − λ(α2 − Xβ), cf. Wooldridge (2010)
14
cf. Table 9
8
9. ($10,000) increases the predicted probability of being "Very happy" of 1.2 percentage point,
decreases the predicted probability of being "Pretty happy" and "Not too happy" of 0.5 and
0.7 percentage point respectively. For more visual results, we can observe at the average point,
the estimated response probabilities computed at each value of inc between 0 and 15 15
. We
observe that, as inc increases, the estimated response probabilities of welfare = 0 or 1|X
decreases, and the estimated response probability of welfare = 2|X increases (cf. Figure 1
& 2). Furthermore the gradient of the predicted response probability of welfare = 0 or 2|X
remains approximately constant as inc increases, this is not the case for the predicated response
probability of welfare = 1|X, for which the gradient decreases as inc increases. Graphically
we conclude that the more income you have, the happier you will be. This idea can obviously
be nuanced.
5.1.2 Nuanced effect of an income increase on welfare
Remember that, Kahneman and Deaton (2010), found that subjective well-being does not
continue to increase as soon as the income reaches a certain value. Results (cf. Table 8) from
(M2) inform us that, the threshold parameters are significant at the 1% level, “ζ1 is positive and
significant at the 1% level and β1 < “ζ1 ⇔ 0.060 < 0.279, it implies that (M1) underestimates
the effect of inc. Indeed, at the average point, if we use (M1), the estimated marginal effect of
inc on welfare = 2|X is about 1.2 percentage point, whereas using (M2) leads the estimated
marginal effect of inc to be 3.3 percentage points, nearly three times more16
. “ζ2 is negative
and significant which implies that above a certain value taken by inc, the predicted response
probability of welfare = 2|X can decrease. We can look at the estimated marginal effect17
of inc on welfare = 2|X to verify that :
∂P[welfare = 2|X]
∂inc
(ζ) = (“ζ1 + 2“ζ2inc)λ(Xζ − ”α2) =
(0.279 − 0.032inc)λ(Xζ − 2.277). As λ(Xζ − 2.277) is always positive, simply find the value
15
the maximum value taken by the income variable in the dataset from GSS is about $131,677 (inc = 13.17),
so we took inc = 15 as the upper bound, cf. Table 4.
16
cf. Table 9 and 10 to compare estimated marginal effects between (M1) and (M2)
17
cf. Appendices, Computation of marginal effects
9
10. of inc, let’s call it inc∗
, such that : 0.279 = 0.032inc∗
, in order to maximize the predicted
response probability of being "Very happy". inc∗
= 8.7187, it means that the predicted response
probability of being "Very happy" increases until the income reaches $87,181 and then start to
decrease a little (cf. Figure 3 & 4 for more visual results18
). This value19
is pretty similar but
no equal to the value found by Kahneman and Deaton (2010) which is $75,00020
. inc∗
is the
value that maximizes the predicted response probability of welfare = 2|X, ∀X. Thereby an
income increase will not lead to the same increase of happiness whether the individual already
has a high income or not, answering the question asked in the introduction.
5.2 Impact of the income on happiness according to the social context
From now on, we will use the results from (M2), as this latter provides more realistic results
than (M1). Concerning the parameters estimates of the control variables representing the social
context : the coefficient estimates associated to married, educ, and work are significant21
and
positive, so we expect a positive impact of these variables on happiness. Ceteris paribus, the
marginal effect when married = 1 on the probability of being "Very happy" at the average
point has to be considered as it in increased this response probability of 13.7 percentage points.
Ceteris paribus, the estimated marginal effect when work = 1 on the probability of being
"Very happy" at the average point increased this response probability of 4.4 percentage points,
we found the same result than Gielen and Van Ours (2012), but this effect on happiness is
minor. The coefficient estimates associated to relig and child are both significant at the 5%
level. Ceteris paribus, at the average point, the partial effect of having one more child on the
response probability of welfare = 2|X decreases this latter by 1.3 percentage point, this result
18
We did not set inc to values greater than 15 ($150,000) for two reasons : it is unrealistic and the individual
is likely to be unhappy for inc tending to +∞.
19
Comparatively, it is also the value for which the predicted response probability of welfare = 0|X is the
lowest.
20
the data used by Kahneman and Deaton (2010) was not the same as they used data from 2009, however
they also used data from United States of America.
21
significant at the 1%, 10% and 5% level respectively.
10
11. has to be considered if the individual has several children, in agreement with Stanca (2012).
Graphically we observe that the more children an individual have, the bigger is the shift of the
curve representing the probability of being "Very happy", compared to not having children (cf.
Figure 12).
To answer the question asked in the introduction, regarding the difference of the impact
of an income increase on happiness between a man and a woman, it seems that there is no
difference as the coefficient estimate associated to female is not significant. It also holds for

5.2.1 Impact of the income on happiness according to the marital status
At the average point we computed the predicted probabilities of the response probabilities of
welfare = j|X according to the level of income, whether the individual is married or not
(cf. Figure 5 & 6). Graphically, we observe that the gap of the probability of being "Very
happy" between a married person and a single one is not the same whether the individual has
a high income or not. Therefore, it can be interesting to compute the difference of probability
of welfare = 2|X after an income increase between a married individual and a single one.
E.g., this difference is about 14.21 percentage points between a single individual and a married
one earning $26,000 a year22
, between a single individual and a married one earning $87,00023
a year it is about 16.77 percentage points. It means that: consider a person at the average
point but earning $26,000 a year, and being single, if this individual has her income changing
from $26,000 to $87,000, her probability of being "Very happy" will obviously increase but not
as much than the same individual being married. This difference24
is about 2.56 percentage
points. The interpretation is that a married person will interpret an income increase better
than a single one, ceteris paribus. In other terms, being married will lead to a bigger expansion

5.2.2 Impact of the income on happiness according to labor force status and
education
At the average point we computed the predicted probabilities of the response probabilities of
welfare = j|X according to the level of income, whether the individual is graduated or not
(cf. Figure 7 and 8) and whether the individual is working or not (cf. Figure 9 and 10). As
in the previous part, graphically we observe that the gap25
between an high-educated person
and a low-educated one (same observation for persons who are working-unemployed) is not the
same whether the individual has a high income or not. It can be relevant to compute difference
of the predicted response probability of welfare = 2|X after an income increase between an
individual who is graduated and a person who is low educated, and also between a person
who is working and a person who is unemployed. We found the same result as in the previous
subsection26
, those who are graduated (educ = 1) are likely to interpret an income increase
better than those who are low educated (educ = 0). Again, between a graduated person and a
low educated, when the income changes from $26,000 to $87,000, here the difference is about
0.9 percentage point (which is minor), ceteris paribus.
Concerning the difference of probability of being "Very happy" between a person who works
and a person unemployed when the income changes from $26,000 to $87,000, this difference is
about 1.25 percentage points which is also minor. But both variables can be taken in account
(cf. Figure 11). Graphically we check that the gap between the blue curve27
and the red curve28
is bigger for high-educated and working people than for low-educated and unemployed ones.

13. 6 Conclusion
To summarize, we have seen the impact of an income increase on happiness on several points
of view. The first results inform us that an income increase does not affect happiness in the
same measure whether the individual is poor or wealthy. Moreover being a man or a woman
does not impact the effect of an income increase on happiness.
One of the most relevant result is that, according to the second model (M2), there exists
a level of income that maximizes happiness29
, this value is around $87,000. Nearly the same
result as Kahneman and Deaton (2010) who found this value around $75,000. We know there
exist wealth inequalities like the fact30
that "the richest 1% have more wealth than the rest
of the world combined", as people are no longer happier above a certain value of income, the
accumulation of wealth can be questioned.
About policy implications, consider a policy maker who wants to maximize the social welfare,
he may take decisions like taxing more people earning $87,000 as above this value people are
not happier and give this amount through social support for those who earn less in order to
enhance their happiness. He can also encourage professional training to allow people to find a
job and invest in education in order to give them chances to be highly educated.
To conclude, we first suggest to other researchers to use data in other countries to compare
results across world regions. Furthermore, to use data with as much of informations as possible
to extend this thematic (about individual health, work stress, leisure time, etc.). Including more
emotional characteristics in the analysis in order to study the impact of happiness is a huge
goal as we all want to maximize social welfare. For instance about work stress, a happy worker
is more productive than someone who is not : everybody is benefiting from social welfare.
