This document discusses economic principles of rural land resource management, including efficiency, optimization, and input-output relationships. It defines efficiency as either physical efficiency, when output is produced on the production possibility frontier at lowest cost, or economic efficiency, when marginal costs equal marginal revenues. Optimization means producing at the point where marginal rate of technical substitution equals 1. Input-output relationships refer to how specific resources like land and water are used to produce outputs like crops. The document explores concepts like production functions, laws of diminishing returns, and how optimal production is where marginal revenue equals marginal cost.
This document provides an introduction to production and resource use. It discusses topics including conditions of perfect competition, classification of productive inputs, production relationships, costs of production, and economics of short-run production decisions. Key concepts covered include the production function, total physical product curve, marginal physical product curve, average physical product curve, stages of production, total costs, average costs, marginal costs, total revenue, average revenue, and marginal revenue. The document uses examples and tables to illustrate these concepts and how firms can determine profit-maximizing output levels under perfect competition.
The document discusses production functions and factors of production. It defines a production function as a relationship between inputs and output, and lists several factors of production including labor, capital, land and entrepreneurship. It also describes the concepts of increasing, decreasing and constant returns to scale, and how a production function can be used to determine optimal input levels and maximize profit.
This document provides an overview of key concepts in cost revenue analysis, including the production process, fixed and variable inputs, short-run versus long-run costs, the production function, marginal product, the law of diminishing returns, economic versus accounting costs, cost curves, revenue analysis, break-even and shutdown points, and scales of production in the long run. It defines important terms and concepts and provides examples to illustrate them.
This document provides an overview of managerial economics concepts. It discusses decision making processes, basic economic analysis tools used in decision making including demand, supply, market equilibrium, elasticity, and market structure. It also covers production and cost analysis concepts such as production functions, cost functions, returns to scale, and optimal input utilization. Additionally, it discusses macroeconomic indicators like GDP, inflation, unemployment, and the business cycle. Finally, it briefly introduces monetary and fiscal policy tools.
1. The document outlines concepts related to production including production functions, efficiency, law of diminishing returns, short-run and long-run production, isoquants, and returns to scale. It provides examples and cases to illustrate these concepts.
2. Key concepts discussed include the production function relating inputs like capital, labor, and land to output. The law of diminishing returns states that adding more of a variable input while holding others fixed initially increases output at a decreasing rate.
3. Isoquants illustrate combinations of inputs that produce the same output level, and the marginal rate of technical substitution measures how inputs can be substituted in production. The document also discusses short-run and long-run analysis and
This document discusses production and cost analysis concepts from a managerial economics textbook chapter. It defines key terms like total, average and marginal product, isoquants, isocosts, and different cost functions. It explains how firms determine optimal input levels by equalizing the value of marginal products with input prices to minimize costs. Firms produce at the point where the marginal rate of technical substitution equals the input price ratio. Cost functions are important for analyzing profit-maximizing behavior.
I. The document discusses production and cost analysis concepts including: production functions, total, marginal, and average product, isoquants, isocosts, and cost minimization.
II. It also discusses cost analysis concepts such as: total, variable, and fixed costs. Total cost is the sum of variable and fixed costs. Variable costs vary with output while fixed costs do not.
III. Multi-product cost functions are discussed as well as economies of scope which occur when it is cheaper to produce multiple products jointly rather than separately.
The document discusses production and cost analysis in business economics. It covers key topics such as:
1) Production functions which define the relationship between inputs like capital, labor, and entrepreneurship and the maximum output that can be produced. Common algebraic forms include linear, Leontief, and Cobb-Douglas functions.
2) Cost functions which determine the cost of producing a given output level using optimal input combinations. Types of costs include short-run and long-run costs. Economies of scale can cause long-run average costs to decrease with increasing output.
3) Differences between economic and accounting costs and profits. Economic costs include opportunity costs while accounting costs consider money spent.

This document discusses four ways to measure national income: nominal GDP at market prices, nominal GDP at factor cost, GDP with green accounting adjustments, and per capita GDP. It also provides instructions on calculating these different income measures using a sample data table. The document then discusses the Foster-Greer-Thorbecke (FGT) method for measuring poverty, which can calculate headcount, poverty gap, and poverty severity indices. It provides a sample data set and instructions for students to calculate these three FGT poverty measures.
This document discusses different concepts in production economics including isocosts, least-cost input combinations, and returns to scale. It defines isocosts as cost curves that represent combinations of inputs that cost the same amount. Least-cost combinations are determined by superimposing isocost and isoquant curves to find points of tangency. Returns to scale refer to how output changes with proportional input changes. Constant returns mean output doubles with doubled inputs. Decreasing returns mean less than doubled output, while increasing returns mean more than doubled output.
This document defines production and costs, and discusses the theory of production and cost. It covers:
1) Definitions of production, inputs, production functions, and the relationship between inputs and output.
2) The characteristics of short-run and long-run production periods and production functions.
3) The measurement of total product, average product, and marginal product and how they relate at different stages of production.
4) Cost concepts including total, fixed, variable, marginal, average, and their relationships as depicted through cost curves.

This chapter discusses the costs of production for a firm. It explains the differences between fixed and variable costs, as well as how average and marginal costs are determined. In the short run, costs are influenced by increasing or decreasing returns. In the long run, the user cost of capital must be considered. Cost curves, including total, average, and marginal costs are presented to show how costs change with different levels of output.
This document discusses various concepts related to cost theory and analysis. It defines different types of costs such as actual, opportunity, explicit, implicit, fixed, variable, accounting, economic, marginal, incremental, sunk, private, social, original, and replacement costs. It also discusses cost functions, the relationship between production and costs in the short-run and long-run, cost curves like total, average, and marginal costs. Finally, it covers special topics like profit contribution analysis, break-even analysis, operating leverage, learning curves, and economies of scope.
This document provides an overview of a macroeconomic model that examines national income. It discusses how total output is determined by factors of production like capital and labor. It then explains how factor prices, like wages and rental rates, are set through supply and demand in factor markets. The model shows how total national income is distributed to factor payments. It also outlines the components of aggregate demand, like consumption, investment, and government spending, and how their equilibrium in the goods market determines total output.

The document discusses key concepts related to national income accounting and measurement. It begins with definitions of gross national product, gross domestic product, net national product, and related terms. It then discusses three approaches to measuring national income: 1) the production or value added method, 2) the income method, and 3) the expenditure method. The summary provides an overview of the key terms and measurement approaches covered in the document.
This program solves the economic dispatch problem using the lambda iteration method for a system with three generating units, both with and without considering transmission losses.
It defines the cost curves and operating limits of each generator. The problem is solved by minimizing total generation cost subject to the load demand constraint, using MATLAB's fsolve function to solve the coordination equations.
Without losses, it calculates the optimal dispatch, total cost and verifies load balance. With losses, it iteratively solves the coordination equations including loss coefficients to determine the optimal dispatch that minimizes total cost including losses, calculating total losses and resulting load supplied.
i) The production function Q = K2⁄3L1⁄3 exhibits constant returns to scale and differs from linear and Leontief production functions.
ii) Given capital of 10 units and labor of 20 units, the average and marginal products of labor are calculated as 44.46 units, 2.22, and 0.001667 respectively using the production function.
iii) The firm would hire labor up to the point where the average product of labor equals the marginal product of labor to minimize costs.
Intermediate Microeconomic Theory Cheat Sheet 3Laurel Ayuyao
1. Production fundamentals include cost minimizing input blends and production functions that specify the maximum output possible from given inputs.
2. Firms produce at the efficient level that maximizes output from inputs while minimizing costs. There are possibilities for increasing, decreasing, and constant returns to scale.
3. Cost and profit maximization problems can be modeled using cost functions, production functions, and marginal analysis to determine optimal input levels and output quantities.
Productivity is a key driver of economic growth according to the theory of aggregate supply. GDP depends on output, which depends on productivity and labor inputs. Using a Cobb-Douglas production function, total factor productivity can be calculated as a weighted average of labor and capital productivity. While East Asian economies grew rapidly in the 1960s-2000s, growth accounting shows most of their growth was due to factor accumulation rather than productivity growth. In fact, capital productivity was declining over this period in these countries. So the East Asian growth experience may not have been a productivity "miracle" as previously thought.

Direct Regulation Externalities in Markets for goods, services or Inputs
Ruth Forsdyke
Regulating Negative Externalities:
1) This problem continues on from the L5 and L6 Practice Problem:
Note: Demand and Supply Curves are hypothetical but roughly intersect world demand and price
point.
QD(P) = 190 – P
QS (P) = 3P/2 – 60
The marginal external cost is: MCExternal = 25$/bbl (assumed low carbon tax of $50/tonne CO2e)
The quantity units are in millions bbl oil/day while the price units are in $US/bbl.
a) Find the marginal Pigouvian tax to regulate this market and plot on your graph. Illustrate how
this shifts the producer’s marginal cost curve.
b) Starting at the point in time immediately after the tax is imposed, explain the process by which
the market moves to the new equilibrium.
c) Use areas under curves to illustrate the following under the tax and indicate whether they rose
or fell:
i) total consumer surplus
ii) total producer surplus
iii) total external costs
iv) total social surplus
v) total tax revenue
d) Find the monetarily socially efficient crude oil quota and label on your graph.
e) Starting at the point in time immediately after the quota is imposed, explain the process by
which the market moves to the new equilibrium.
f) Use areas under curves to illustrate the changes in the following due to the quota:
i) total consumer surplus
ii) total producer surplus
iii) total external costs
iv) total social surplus
v) total quota rent (goes to firms if given away, goes to government if auctioned in
perfectly competitive market with no corruption, i.e. regulatory capture).
Variable vs Fixed External Costs:
2) Suppose that you take a return trip by Air from Halifax to Vancouver and back. The GHGs due
to combustion of the fuel used to power your trip are approximately 1 tonne of CO2e. Suppose the
price of carbon dioxide is $200/tonne CO2e. This is only part of your carbon footprint—by taking
the trip, you are also responsible for some very small fraction of the emission used during the air
plane’s product life cycle and also that of the air port. These get diluted out over many people and
so your airplane trip still has a carbon footprint of about 1 tonne. Like private costs, external costs
can be either fixed or variable. Identify some variable and fixed external costs of your trip.
Positive Externalities from Forests:
3) Consider the town of Thneedville. Their monetary marginal willingness to pay for a truffala
forest is: MWTP = 10 – Q/2 (in millions of $/hectare)
Suppose that the monetary marginal opportunity cost of the forest is cutting down the forest to
make thneeds is MCPrivate = 10Q (in millions of $/hectare)
Suppose that the forest stores 2000 tonnes of CO2e/ hectare and that it is estimated that the price of
carbon dioxide is $20,000/ tonne.
This problem is complicated in reality because it takes time to grow a forest during which c ...
The firm is an economic institution that transforms factors of production into consumer goods – it:
Organizes factors of production.
Produces goods and services.
Sells produced goods and services.
This document discusses production functions and the laws of production. It defines production as the transformation of inputs into outputs of goods and services. There are two types of production functions - fixed and variable proportions. The law of variable proportions describes the relationship between varying input levels and output in the short run when one input is variable. Diminishing marginal returns typically occur as more of the variable input is added due to scarcity of the fixed inputs. Isoquants illustrate combinations of two variable inputs that produce the same output level.

Basic Economic Principles of Land Resources
Two main economic principles of land resource
management are efficiency and optimization.
Both are critical to sustainable rural land
resources management at least for three reasons,
namely to:
* increase output without increasing land area
(increase productivity)
* ensure full employment of resources to the
extent whereby each of them is equally
productive
* attain cost effectiveness in production

(PPF) or at lowest possible cost. Also called
productive or technical efficiency.
(2) Economic efficiency: when each additional input
cost incurred equals each additional output
revenue. Also called allocative efficiency.
5. Economic & Management Aspects of
Rural Land Resources 5
• PPF is a concave
curve due to disparity
in factors’ levels of
intensities and
technologies of the
two sectors
• Higher marginal
costs become
inevitable due to
diminishing marginal
returns in the
production of each
good
Productive or technical efficiency
6. Economic & Management Aspects of
Rural Land Resources 6
▪ PPF is based on the
concept of opportunity
cost – amount of one
output forsaken to
increase amount of
another
▪ Rate at which opportunity
cost changes is called
marginal rate of technical
substitution (MRTS)

Economic or Allocative Efficiency
Market condition whereby resources are allocated
in a way that maximizes the net benefit attained
through their use
A situation in which the limited resources of a
country are allocated in accordance with the
wishes of consumers
Allocatively efficient economy produces an
"optimal mix" of commodities
A firm is allocatively efficient when its price is equal
to its marginal costs (that is, P = MC).
9. Economic & Management Aspects of
Rural Land Resources 9
Production process that satisfies both technical and
economic efficiency
When output is produced where:
(1) MR = MC
Additionally, in case of multi-output, say A and
B:
(2) MVPA= MVPB
(3) MRTSA,B = 1
where MR = marginal revenue, MC = marginal cost,
MVP = marginal value product, and MRTS =
marginal rate of technical substitution (A/B)
May be reflected through production that maximises
revenue or profit
Optimality
10. Economic & Management Aspects of
Rural Land Resources 10
Optimum production – maximising revenue/profit
• Budget constraints
(FA and FB) are
imposed on PPF
• FB is budget use in
case of under-
production
• FA is budget use in
case of efficient
production
• However, only point
A yields optimum
production

12. Economic & Management Aspects of

Goat = 30 + 0.4*Sheep - 0.094*Sheep2 (PPF)
Goat = 36.17 - 1.096*Sheep (Budget line)
From PPF : dPPF(Goat)/dPPF(Sheep) = 0.4 - 0.188*Sheep
From Budget line: dBL(Goat)/dBL(Sheep) = -1.096
At tangential point, dPPF(Goat)/dPPF(Sheep) = dBL(Goat)/dBL(Sheep)
Thus, 0.4 - 0.188*Sheep = -1.096
Sheep = (0.4+1.096)/0.188
= 7.96
≈ 8
From PPF: Goat = 30 + 0.4*8 - 0.094*82
= 30 + 3.2 - 6.016
≈ 27
Total cost = 188 x 27 + 206 x 8
= 5,076 + 1,648
= 6,724
Total revenue = 350 x 27 + 400 x 8
= 9,450 + 3,200
= 12,650

Some resources are specifically used in the
production of economic goods or services
E.g. land (L) and water (W) are used to grow
paddy
This is called input-output relationship
Mathematically P = f(L, W)

Y = f(x) (single-input production)
Y = f(x1, x2) (two-input production)
Y = f(x1, x2,…,xm) (multi-input production)
Most economic production is multi-input: an output
is produced via a combination of resources, e.g.
land, capital, labour, fertilizer, water, temperature,
labour, etc.
Input-output relationship of most production differ

Different enterprises may have different
productivity and thus production functions

Logical answer = 15.83 years

At Year = 15.83, TR = 1,200 + 0.75*15.83 + 10.5*15.832 – 1.5*15.833/3.543
