Comparison of the SR and LR Average Costs at Output Q1 (or any other output level). The LRAC curve shows the minimum average cost at which each quantity . A short-run marginal cost curve graphically represents the relation between . Both the SRAC and LRAC curves are typically expressed as U-shaped. If f is the equation for a line, then there are two real numbers m and b such that y = mx +. The firm's current opportunity cost of capital may be less than what it .. 0. 4. 2, 5, q, pages. SRAC of laser printer. SRAC of ink-jet printer. LRAC.
Average fixed cost AFC: As output increases, total cost first increases at a decreasing rate, then increases at an increasing rate.
Nests Quadratic and Linear!!! As output increases, total cost increases at an increasing rate. As output increases, total cost increases at a constant rate. Because there are no fixed inputs, there are no fixed costs. The firm s long run average cost pertains to returns to size. First, increasing returns to size: Costs fall as Q.
As firms mature, they achieve constant returns, then ultimately decreasing returns to scale.
A proportional increase in all inputs increases output by a greater proportion. As output increases by some percentage, total cost of production increases by some lesser percentage. Specialization in the use of labor and capital. Prices of inputs may fall as the firm realizes volume discounts in its purchasing. Use of capital equipment with better priceperformance ratios.
Larger firms may be able to raise funds in capital markets at a lower cost than smaller firms. Larger firms may be able to spread out promotional costs. Scale of production becomes so large that it affects the total market demand for inputs, so input prices rise.
Transportation costs tend to rise as production grows. Handling expenses, insurance, security, and inventory costs affect transportation costs. Once it commits to a level of capacity, at least one of the inputs must be fixed. This then becomes a shortrun problem.

Downward slope indicates additional cost per unit declines as the level of output increases because workers improve with practice. Measured in terms of percentage decrease in additional labor cost as output doubles. Closely related to economies of scale.Long-run Average Cost Curve PART-8::Difference between LAC curve and SAC curve.
The same source reviews a range of included in principles of economics textbooks. Among economists more generally, it argues that a particular definition presented may reflect the direction toward which the author believes economics is evolving, microeconomics examines how entities, forming a market structure, interact within a market to create a market system 2.

Partial equilibrium — Partial equilibrium is a condition of economic equilibrium which takes into consideration only a part of the market, ceteris paribus, to attain equilibrium. The supply and demand model is an equilibrium model where the clearance on the market of some specific goods is obtained independently from prices and quantities in other markets. In other words, the prices of all substitutes and complements and this makes analysis much simpler than in a general equilibrium model which includes an entire economy.
Here the dynamic process is that prices adjust until supply equals demand and it is a powerfully simple technique that allows one to study equilibrium, efficiency and comparative statics. Hence this analysis is considered to be useful in constricted markets, commodity price is given and constant for the consumers. Consumers taste and preferences, habits, incomes are also considered to be constant, prices of prolific resources of a commodity and that of other related goods are known as well as constant.
Industry is easily availed with factors of production at a known, prices of the products that the factor of production helps in producing and the price and quantity of other factors are known and constant. There is perfect mobility of factors of production between occupation and places, the above-mentioned points relate to a perfectly competitive market but can be further extended to monopolistic competition, oligopoly, monopoly and monopsony markets.
Equilibrium for an industry happens when there is normal profit made by an industry It is such a situation when no new firm wants to enter into it and the existing firm does not want to exit. The quantity of factors which its owners want to sell should be equal to the quantity which the entrepreneurs are ready to hire and it is restricted to one particular portion of the economy. It lacks the ability to study the interrelations of all the parts of the economy and this analysis will fail if the improbable assumptions, which disconnect the study of specific market from the rest of the economy, are not taken into consideration.
In partial equilibrium the welfare effects on consumers who purchase and the producers who produce in the market is distinguished by consumer surplus, the amount that a consumer is ready to pay for a particular good minus the amount that the consumer actually pays 3. Factors of production — In economics, factors of production, resources, or inputs are what is used in the production process to produce output—that is, finished goods and services.
The utilized amounts of the various inputs determine the quantity of output according to a relationship is called the production function, there are three basic resources or factors of production, land, labor and capital. The factors are also frequently labeled producer goods or services to them from the goods or services purchased by consumers.
All three of these are required in combination at a time to produce a commodity, there are two types of factors, primary and secondary. The previously mentioned primary factors are land, labor, and capital goods, materials and energy are considered secondary factors in classical economics because they are obtained from land, labour and capital.
The primary factors facilitate production but neither become part of the product nor become significantly transformed by the production process, land includes not only the site of production but natural resources above or below the soil. Recent usage has distinguished human capital from labor, entrepreneurship is also sometimes considered a factor of production.
Sometimes the overall state of technology is described as a factor of production, the number and definition of factors varies, depending on theoretical purpose, empirical emphasis, or school of economics. Differences are most stark when it comes to deciding which factor is the most important, however, other authors argue that entrepreneurship is nothing but a specific kind of labor or human capital and should not be treated separately.
The Marxian school goes further, seeing labor as the factor of production, since it is required to produce capital goods. But this debate is more basic economic theory than it is about the definition of the factors of production. The payment for use and the income of a land owner is rent. Labor — human effort used in production also includes technical. The payment for someone elses labor and all received from ones own labor is wages.
Labor can also be classified as the physical and mental contribution of an employee to the production of the good, the capital stock — human-made goods which are used in the production of other goods. These include machinery, tools, and buildings, the classical economists also employed the word capital in reference to money.
Money, however, was not considered to be a factor of production in the sense of capital stock since it is not used to produce any good. The return to loaned money or to loaned stock was styled as interest while the return to the proprietor of capital stock was styled as profit 4.
American Economic Association — The American Economic Association is a learned society in the field of economics, headquartered in Nashville, Tennessee. It publishes one of the most prestigious journals in economics.
The Association as such will take no partisan attitude, nor will it commit its members to any position on economic questions.
Its current president is Alvin E. Roth of Stanford University, once composed primarily of college and university teachers of economics, the Association now attracts an increasing number of members from business and professional groups. Init began to publish four new area-specific journals, the four areas covered by AEJ are applied economics, economic policy, macroeconomics, and microeconomics.
It is an index to peer-reviewed journal articles, books, book reviews, collective volume articles, working papers. Compiled and abstracted in a format, EconLit indexes years of economic literature from around the world. The AEA resource, Job Openings for Economists originated in OctoberAEA, in conjunction with over 50 associations in related disciplines, holds a three-day annual meeting to present papers on general economic subjects.
This meeting features about scholarly sessions, a placement service to assist employers and job applicants begins a day prior to the meetings. A continuing education program is held immediately after the annual meeting, topics vary from year to year. Each year, the AEA recognizes the lifetime research contributions of four economists by electing them Distinguished Fellows, the most recent winner is Yuliy Sannikov.
Accompanying statements for years before may be found in the year of the American Economic Review 5. Point of total assumption — The seller bears all of the cost risk at PTA and beyond, due to a dollar for dollar decrease in profit beyond the costs at the PTA.
In addition, once the costs on an FPI contract reach PTA, any FPI contract specifies a target cost, a target profit, a target price, a ceiling price, and one or more share ratios. The PTA is the difference between the ceiling and target prices, divided by the portion of the share ratio for that price range.
If for a moment, PTA is given and you are trying to calculate the price for the buyer. This is a used in project management when managing specific fixed price contracts.
The reason to calculate PTA is that when executing the contract, compare this measurement with the cost base line to calculate Cost Performance Index, then we can estimate the cost at Completion. If EAC exceeds PTA, the buyer is expected to pay the ceiling price, the profit decrease rate become higher, and once actual cost exceeds ceiling price the seller will start losing money.
For cost reimbursable contract, the Point of Total Assumption does not exist, however, a similar incentive arrangement with similar components, called a Cost-Plus-Incentive Fee contract sometimes is used. The CPIF includes both a fee and a maximum fee. The share line in combination with the Target Fee, Maximum Fee, the range between these points is called the range of incentive effectiveness.
The idea of a Point of Total Assumption is a recent one. The contract type is implemented by calling out FAR Clause If multiple line items are identified as FPI type, the line item information shall be included here, otherwise final contract costs.
Twelve issues are published annually by the American Economic Association, first published init is considered one of the most prestigious and highly distinguished journals in the field of economics. The current editor-in-chief is Esther Duflo, the previous editor was Pinelopi Goldberg. Selected papers and discussions of papers presented at the Annual Meetings of the American Economic Association are published along with reports of officers, committees, and representatives.
Inthe American Economic Review began requiring data and code sufficient to permit replication of a papers results, exceptions are made for proprietary data. The Use of Knowledge in Society, by F.

In both andit was the most widely viewed journal of all the journals in JSTOR, other notable papers from the journal include, Colonial origins of comparative development, by Daron Acemoglu, Simon Johnson, and James A.
Originally containing digitized back issues of journals, it now also includes books and primary sources. It provides full-text searches of almost 2, journals, more than 8, institutions in more than countries have access to JSTOR, most access is by subscription, but some older public domain content is freely available to anyone. Bowen, president of Princeton University from toJSTOR originally was conceived as a solution to one of the problems faced by libraries, especially research and university libraries, due to the increasing number of academic journals in existence.
Most libraries found it prohibitively expensive in terms of cost and space to maintain a collection of journals. By digitizing many journal titles, JSTOR allowed libraries to outsource the storage of journals with the confidence that they would remain available long-term, online access and full-text search ability improved access dramatically. JSTOR access improved based on feedback from its sites. Special software was put in place to make pictures and graphs clear, with the success of this limited project, Bowen and Kevin Guthrie, then-president of JSTOR, wanted to expand the number of participating journals.
