Benefit-Cost Analysis,

    Benefit-Cost Analysis, from the Concise Encyclopedia of Economics
    Whenever people decide whether the advantages of a particular action are likely to outweigh its drawbacks, they engage in a form of benefit-cost analysis....
    What if a change benefits some people at the expense of others? John R. Hicks, biography from the Concise Encyclopedia of Economics
    Hicks's fourth contribution was the idea of the compensation test. Before his test economists were hesitant to say that one particular outcome was preferable to another. The reason was that even a policy that benefited millions of people could hurt some people. Free trade in cars, for example, helps millions of American consumers at the expense of thousands of American workers and owners of stock in U.S. auto companies. How did an economist judge whether the help to some outweighed the hurt to others?...

    Costs and Benefits of going to the dentist: The Marginal Tooth, by Bryan Caplan on EconLog
    Every patient gets the same lecture: "If you don't floss, you'll loose your teeth. I told you this last time, and you're still not flossing!" Has it ever occurred to dentists that the marginal benefit of flossing may be less than its marginal cost?...
    Costs and Benefits of preventing crime: Crime, from the Concise Encyclopedia of Economics
    Economists approach the analysis of crime with one simple assumption—that criminals are rational people. A mugger is a mugger for the same reason I am an economist—because it is the most attractive alternative available to him. The decision to commit a crime, like any other economic decision, can be analyzed as a choice among alternative combinations of costs and benefits....
    Costs and Benefits of recycling: Recycling, from the Concise Encyclopedia of Economics
    Recycling is the process of converting waste products into reusable materials. Recycling differs from reuse, which simply means using a product again. According to the Environmental Protection Agency (EPA), about 30 percent of U.S. solid waste (i.e., the waste that is normally handled through residential and commercial garbage-collection systems) is recycled. About 15 percent is incinerated and about 55 percent goes into landfills.

    Recycling is appealing because it seems to offer a way to simultaneously reduce the amount of waste disposed in landfills and to save natural resources....
    Hidden Costs. The promoter of an idea typically plays up the benefits and plays down the costs. Economists delight in uncovering those hidden costs and often enjoy a moment of fun by taking the promoter by surprise.
    See: "What is Seen and What is Not Seen", Frédéric Bastiat(pronounced bas-tee-AH). Famous essay about what economists do, emphasizing their role in pointing out the unseen, unspoken costs behind great-sounding ideas.

A Little History

    However hard it is to total up the costs and benefits (or pros and cons) to make individual decisions like "Should I rent this apartment?" or "Should I spend a year abroad?", it's even harder when groups are involved. Should one person decide for the group? Should it be decided by 50-50 vote, or representation? Individuals do pretty well weighing the costs and benefits for close groups, like our families, by proxy—our parents, brothers and sisters, children, and spouses. But each extension to a wider group gets harder to justify. How should the desires be balanced when considering broad groups of people with different goals and opporunities—from extended family, to high school friends, to college communities, to towns, cities, religious groups, cultural affiliations—or a whole nation or cross-national cultural group? How can we decide when there is disagreement or conflict? See the biography of Nobel Prize winner Paul Samuelson for aggregating utility functions and revealed preference.
    [Samuelson] introduced the concept of "revealed preference" in a 1938 article. His goal was to be able to tell by observing a consumer's choices whether he or she was better off after a change in prices, and indeed, Samuelson determined the circumstances under which one could tell. The consumer revealed by choices his or her preferences--hence the term "revealed preferences."

MONETARY POLICY, CONCEPT, OBJECTIVES, IMPORTANCE

MONETARY POLICY


1       Concept of Monetary Policy
            Monetary policy is one of the successful macro-economic policies. It has important role for in general economic management and growth. Monetary policy is the work out of the central bank to control over the money supply as a tool for achieving the objectives of universal economic policy. Monetary policies attempt to make different types of good quality economic activities mainly through money and credit supply as well as interest rate. Similarly, monetary policy will be more successful through the period of galloping or hyperinflation.
            The process, formulation, completion and estimate of monetary policy are calculated by the central bank under the rules and directives of government of the state as well as increase and development of an economy. Therefore, monetary policy is adopted to achieve different types of economic objectives like accelerated economic growth and progress, full service, price constancy, economic constancy etc. So monetary policy can be defined as the management of the expansion and contraction of quantity of money in movement. So we can say, monetary policy can change quantity, quality, availability and cost of money as well as rate of interest, investment, service, output, revenue etc. for the balance economic growth and development.
            According to Edward Shapiro "Monetary policy is the exercise of the central bank's control over the money supply as an instrument for achieving the objective of general economic policy". In the words of D.C. Rowen, "The monetary policy is defined as discretionary action undertaken by the authorities designed to influence (a) the supply of money, (b) cost of money or rate of interest, and (c) the availability of money". According to RP Kent monetary policy is, "The management of expansion and contraction of the volume of money in circulation for the explicit purpose of attaining a specific objective such as full employment".
            Hence, we can say monetary policy is a purposeful effort of central bank to control monetary policy and ratio of credit in an economy for achieving definite objective like economic stability and best allocation of resources. So monetary policy is measured as an important tool of the government to plan various types of economic policies. The main instruments of monetary policy and bank rate, open marketplace operation and required reserve ratio.
            Generally, there are two types of monetary policies according to economic arrangement of an economy i.e. expansionary monetary policy and concretionary monetary policy.
(A)  Concretionary Monetary Policy
            The usefulness of concretionary monetary policy is appeared through the time of hyperinflation, where prices are rising very rapidly and most of the economic variables start to fall. In such state, monetary policies are formulated to manage money supply and expenditure pattern by lowering the insist for consumption and investment some techniques for concretionary monetary prices are:
(a)  Selling the bonds, securities and treasury bills in the open market.
(b)  Increasing the discount rate.
(c)   Rising the minimum required reserve ratio.

(A)  Expansionary Monetary Policy
            The monetary policy, which normally expands money supply and credit in an economy are called expansionary monetary policy. Usually, to increase various economic activities in increasing countries such as trade, commerce, industry and infrastructure development; the expansionary monetary policies are applied some techniques for expansionary monetary policy are:
(a)  buy of bonds and funds bills in open market.
(b)  Lowering the diminution rate or bank rate.
(c)  Lowering the requisite reserve ratio.

            Hence, the monetary policy used by the central bank to fulfill the objective of country's economic policy which is related to supply of money, credit creation, interest rate, exchange rate etc.

2       Objectives of Monetary Policy
            Monetary policy is one of the great tools to stabilize the economic systems. It contains the following objectives:
(i)   Price constancy: The most important objective of monetary policy is to establish internal price stability. Stable price does not means that the average of prices on the general price level should not be allowed to fluctuate beyond certain minimum limit. Price instability creates great disturbances in the economy and helps to create inflation or deflation. Both are economically disturbing and socially undesirable. Both can create problems of production and distribution.
            Thus to establish price stability central bank should properly control the quantity of money and credit. So, the monetary policies are designed by central bank through by changing open market operation, bank rate and minimum required ratio. During the period of inflation, government issues different types securities and the selling of securities in open market absorbs bills and excess money. Similarly, central bank increases bank rate and minimum required ratio to control the problem of inflation.
(ii)  Attain complete service: joblessness is the cancer of an economy. Until the joblessness remains the same, economy cannot progress. joblessness is associated with low investment. Monetary policy can help the economy to achieve full employment through the increment of investment. Unemployment is mainly due to deficiency of investment. The main task of monetary policy is the expansion of money provides and the reduction of interest rate to that optimum level which raises the investment, demand and equals it with full employment.
(iii) Replace rate constancy: It is a traditional objective to establish exchange rate stability, but very important objective of monetary policy. Stable exchange rate helps to create international beliefs and for the promotion of smooth trade. Fluctuations in the exchange rates adversely affects in the volume of trade, price levels, production, balance of payment, foreign investment etc.
            The objective of exchange rate stability is achieved through establishing equilibrium in the balance of payment. Monetary policy plays an important role in bringing balance of payments balance without disturbing the stable exchange rate. The modern welfare governments are more concerned with establishing internal price stability quite than maintaining exchange stability because of international monetary fund.
(iv) Accelerate profitable progress: One of the major objectives of monetary policy is to accelerate economic development. Economic development involves the increase in the productive capacity of the economy by developing additional economic resources, improving technology and exploiting new investment opportunities. For this, it is necessary to increase the rate of capital formation and investment because the levels of saving and investment are very low. Directly or indirectly monetary policy helps to increase capital formation and investment, through encouraging savings and concept of investment.
(v)  Impartiality of cash: various economists such as Robertson, Hayek and Wicksteed developed the neutrality of money. The policy of neutrality of money seeks to do away with the disturbing effect of changes in the quantity of money on important economic variables, like income, output, employment and prices. According to this policy, money supply should be neutral in such a way that money should be neutral its effects. In other words, the changes in money supply should not change the total volume of output and total transactions of goods and services in the economy.
            The policy of neutrality of money is based on the assumption that money is purely a passive factor. It functions only as a medium of exchange. The function of money is only to reproduce the relative values of goods and not to distort them. The exponents of the neutral monetary policy believed that monetary changes are the root case of all economic ills. They bring changes in the real variables such as income, output, employment and relative prices. They cause inequity between demand and supply, consumption and production.
            Thus, according to the policy of impartial money, if the money is made neutral and the money supply is kept constant, there will be no disturbance in the economic system. In such a situation, relative prices will change to the changes in the demand and supply of goods and services, economic resources will be allocated according to the wants of the society, and there will be no inflation and deflation. However, this policy is based on classical assumptions. It cannot control the economic insecurity and fluctuations in the economy.

3.      Importance/Objectives of Monetary Policy in Developing Countries
            The implication of monetary policy may be explained as follows:
            The citizen like inflation, deflation, lack of employment opportunity, investment, output income etc defines developing country as a country where different types of economical and social harms are facing. In developing countries various types of economical problems are solved through the monetary policy. Monetary policy influences most of all inexpensive variables and activities through change in money supply in circulation and rate of interest.
            So suitable monetary is formulated and implemented according to economic structure of an economy. The main importance of monetary policy is developing countries are summarized on following points.
(i)   Progress Role: Monetary policy plays a significant role in developing countries in accelerating economic development by influencing the money supply and rate of interest. Monetary policy is able to create hearten towards investment by the help of scheming inflation and deflation. Similarly, correction of balance of payment plays an important role for over all economic progress. That's why monetary policy is able to run about development activities through by changing bank rate and minimum required ratio.
(ii)  Stepping up to Economic progress: In developing countries, the monetary policy should aim at promoting economic development. The monetary policy can play a vital role in acceleration to economic development. It influences the supply and uses of credit. Controlling inflation and maintaining equilibrium balance of payment.
(iii) Progress of Banking and Financial organizations: One of the main functions of central bank or primary aim of monetary policy is to establish more banks and financial institutions. Underdeveloped countries lack these facilities. These facilities will help in increasing banking habit, mobilizing voluntary savings of the people, channel zing them into productive uses and raising the rate of capital formation.
(iv) Debt organization: In the developing economy, debt management is one of the main functions of monetary policy. The tools under the aims of debt management are deciding correct timing and issuing of government bonds, stabilizing their prices and minimizing the cost of servicing the public debt. These tools collect the means and sources of economic development. Monetary policy helps it in goal specific way.
(v)  Facilitate to manage price increases: Monetary policy is an effective measure to control inflation. It plays a significant role in checking inflation. Increase in government expenditure on developmental schemes increase aggregate demand but collective supply of consumer's goods does not increase in the same time. This increases the price level. The monetary policy controls inflationary tendencies by growing saving, checking expansion of credit by banking system and hopeless deficit financing by the government through tightening monetary policy.
(vi) Help to accurate the unfavorable balance of payment: Monetary policy in the form of interest rate policy plays as important role in corrects the balance of payments deficit. In the developing countries like Nepal, there is serious balance of payment difficulties to fulfill the planned targets of development. To develop infrastructure' such as power, irrigation, transport, etc. and directly productive activities like iron, steel, chemicals, electrical, fertilizers, etc., developing countries have to import capita] equipment, machinery, raw materials, spares and components thereby raising their imports. The exports are almost stagnant. They are high priced due to inflation. As results, an imbalance is created between imports and exports, which lead to misbalance in the balance of payments. Monetary policy can help in decreasing the gap balance of payments deficit through high rate of interest. The high rate of interest attracts the inflow of the foreign investments and help in bridging the balance of payment gap.
(vii) Reduction of Economic Inequality: In an underdeveloped economy, there is wide disparity of income and wealth and absence of an integrated interest rate structure. Monetary policy can play a significant role to maintain equal distribution of income and wealth and a suitable rate of interest rate. The central bank should take effective steps that benefit the poor and to integrate the interest rate structure of the economy. For this, low rate of interest should be fixed for the poor and small farmers, and entrepreneurs and subsidy may be given for them. A suitable interest rate structure encourages savings and investment in economy and discourages unproductive loans and speculative.

4.      Expansionary Monetary Policy to manage Recession or Depression
            When the economy is faced with recession or involuntary cyclical unemployment, which comes due to fall in aggregate demand, the central bank intervenes to cure such a situation. Central bank takes steps to expand the money supply in the economy and lower the rate of interest with a view to increase the aggregate demand that will help in stimulating the economy. The following three monetary policy measures are adopted as a part of an expansionary monetary policy to measures are adopted to cure recession and to establish the equilibrium of national increase at full employment level of output.
(i)   Release marketplace process: The central bank undertakes open market operations and buys securities in the open market. Buying to securities by the central bank, from the public, chiefly from commercial banks will lead to the increase in reserves of the banks or amount of currency with the general public. With greater reserves, commercial banks can issue more credit to the investors and businessmen for undertaking more investment. More private investment will cause aggregate demand curve to shift upward. Thus buying of securities will have an expansionary effect.
(ii)  Reduce in Bank Rate: The Central Bank may lower the bank rate or what is also called discount rate, which is the rate of interest charged by the central bank of country on its loans to commercial banks. At a lower bank rate, the commercial banks will be induced to borrow more from the central bank and will be able to issue more credit at the lower rate of interest to businessmen and investors. This will not only make credit cheaper but also increase the availability of credit or money supply in the economy. The expansion in credit or money supply will increase the investment demand, which will tend to raise aggregate output and income.
(iii) Decrease of Cash Reserve Ratio (CRR): Thirdly, the central bank may reduce the Cash Reserve Ratio (CRR) to be kept by the commercial banks. In countries like India, this is a more effective and direct way of expanding credit and increasing money supply in the economy by the central bank. With lower reserve requirements, a large amount of funds is released for providing loans to businessmen and investors. As a result, credit expands and investment increases in the economy, which has an expansionary effect on output and employment.

5       Contraction Monetary Policy to manage Inflation
            When aggregate demands rises sharply due to large consumption and investment expenditure or more importantly, due to the large increase in government expenditure relative to its revenue resulting in huge budge deficits, a demand-pull inflation occurs in the economy. Besides, when there is too much creation of money for one reason or the other, it generates inflationary pressures in the economy. The following monetary measures, which constitute tight money policy, are generally adopted to control inflation:
(i)   Promotion rule Securities: The Central Bank sells the Government securities to the banks, other depository institutions and the general public through open market operations. This action will reduce the reserves with the banks and liquid funds with the general public. With less reserve with the banks, their lending ability will be reduced. Therefore, they will have to reduce their demand deposits by refraining from giving new loans as old loans are paid back. As a result, money supply in the economy will shrink.
(ii)  Add to Bank Rate: The bank rate may also be raised which will discourage the banks to take loans from the central bank. This will tend to reduce their liquidity and also induce them to raise their own lending rates. Thus this will reduce the availability of credit and also raise its cost. This will lead to the reduction in investment spending and help in reducing inflationary pressures.
(iii) Adapting Anti-inflationary actions: The most important anti-inflationary measures are the raising of statutory Cash Reserve Ratio (CRR). To meet the new higher reserve requirements, banks will reduce their lending. This will have a direct effect on the contraction of money supply in the economy and help in controlling demand pull inflation. Besides Cash Reserve Ratio (CRR), the Statutory Liquidity Ratio (SLR) can also be increased through which excess reserves of the banks are mopped up resulting in contraction in credit.
(iv) Use of Qualitative acknowledgment manage calculate: Fourthly, an important anti-inflationary measure is the use of qualitative credit control, namely, rising of minimum margins for obtaining loans from banks against the stocks of sensitive commodities such as food grains, oilseeds, cotton, sugar, vegetables oil. As a result of this measure, businessmen themselves will have to finance to a greater extent the holding of inventories of goods and will be able to get less credit from banks.




Welfare, GDP Fetishism , Inequality, Consumption, & Happiness.

Introduction

    The word "welfare" has two very different meanings in economics. The most familiar meaning to the general public is that it refers to a collection of government programs such as food stamps and Medicare, usually intended to help the poor.
    However, economists more often use the word "welfare" in a very different sense--as a synonym for wellbeing. Welfare or wellbeing refer to an overall condition, emphasizing happiness and contentment, though also including one's standard of living in financial or material ways. Welfare in this sense more commonly refers to the condition of an entire country or economy, which is sometimes emphasized by using the phrase "social welfare." Welfare in the sense of wellbeing turns out to be an easier concept to imagine than to analyze carefully. It is even harder to measure.
    Economists have always recognized that not all happiness derives from being financially well off. We all know that being wealthy is not the same as being happy. However, it is rather hard to quantify happiness, and even harder to aggregate happiness across people because people generally have a variety of tastes. Consequently, over the years economists have invented some specialized technical names for happiness, including utility, satisfaction, preferences, tastes, indifference curves, wellbeing, and welfare.
    The concept of social welfare sometimes leads to discussions of the distribution of income and income inequality.

Definitions and Basics

    GDP Fetishism 
    When economics professors teach the basics of Gross Domestic Product (GDP), we usually caution our students that it is not a good measure of welfare. Unfortunately, many economists go on to give GDP far more credit than it deserves. They tend to consider fiscal and monetary policy positive if these policies increase GDP, but they often fail to ask, let alone answer, whether those same policies increase or reduce welfare. I have a term for giving GDP such a sacred a place in economists' reasoning: GDP fetishism. If we return to some basic principles of economics, we will avoid GDP fetishism, do better economic analysis, and propose better policies.

    To see why GDP is not the same as wellbeing [I use "welfare" and "wellbeing" interchangeably], consider the definition of GDP. One of the most careful definitions is in The Economic Way of Thinking, 10th edition, by Paul Heyne, Peter Boettke, and David Prychitko. They write: "The gross domestic product is the market value of all the final goods produced in the entire country in the course of a year." Most economists would agree with this definition. It turns out, though, as Heyne et al. point out, that even this careful definition does not accurately characterize GDP, let alone wellbeing. It is inaccurate in two ways. First, because there is usually no market for the things that government produces (the U.S. Postal Service being one of the exceptions), government spending on goods and services is valued at cost rather than at market prices. Second, because many goods and services are not bought or sold, even though they would have a market value if they were, these goods and services are not counted in GDP. In early editions of his best-selling textbook, Economics, the late Paul Samuelsongave his favorite example of this pitfall in GDP accounting. Samuelson pointed out that if a man married his maid, then, all else equal, GDP would fall....
    Welfare, 
    The U.S. welfare system would be an unlikely model for anyone designing a welfare system from scratch. The dozens of programs that make up the "system" have different (sometimes competing) goals, inconsistent rules, and over-lapping groups of beneficiaries. Responsibility for administering the various programs is spread throughout the executive branch of the federal government and across many committees of the U.S. Congress. Responsibilities are also shared with state, county, and city governments, which actually deliver the services and contribute to funding.

    The six programs most commonly associated with the "social safety net" include: (1) Temporary Assistance for Needy Families (TANF), (2) the Food Stamp Program (FSP), (3) Supplemental Security Income (SSI), (4) Medicaid, (5) housing assistance, and (6) the Earned Income Tax Credit (EITC). The federal government is the primary funder of all six, although TANF and Medicaid each require a 25-50 percent state funding match. The first five programs are administered locally (by the states, counties, or local federal agencies), whereas EITC operates as part of the regular federal tax system. Outside the six major programs are many smaller government-assistance programs (e.g., Special Supplemental Food Program for Women, Infants and Children [WIC]; general assistance [GA]; school-based food programs; and Low-Income Home Energy Assistance Program [LIHEAP]), which have extensive numbers of participants but pay quite modest benefits....


    Inequality, Consumption, & Happiness. 
    How well-off are we? Using economic data, economics professor Steve Horwitz addresses questions about inequality, consumption, happiness, and well-being. Are the rich getting richer and the poor getting poorer? Is there income mobility in the United States? Are Americans happy? Are we "objectively" better off than we used to be? ...
    Richard Epstein on Happiness, Inequality, and Envy.
    Richard Epstein of the University of Chicago talks with EconTalk host Russ Roberts about the relationship between happiness and wealth, the effects of inequality on happiness, and the economics of envy and altruism. He also applies the theory of evolution to explain some of the findings of the happiness literature....
    Marginalism, 
    Adam Smith struggled with what came to be called the paradox of "value in use" versus "value in exchange." Water is necessary to existence and of enormous value in use; diamonds are frivolous and clearly not essential. But the price of diamonds--their value in exchange--is far higher than that of water. What perplexed Smith is now rationally explained in the first chapters of every college freshman's introductory economics text. Smith had failed to distinguish between "total" utility and "marginal" utility. The elaboration of this insight transformed economics in the late nineteenth century, and the fruits of the marginalist revolution continue to set the basic framework for contemporary microeconomics.

TYPES OF MICRO ECONOMICS

     The analysis of microeconomics is always affected by time period. But there are still some economists who do not believe the time value...
