Markets Economists study trade, production and consumption decisions, such as those that occur in a traditional marketplace. Electronic trading brings together buyers and sellers through an electronic trading platform and network to create virtual market places. Microeconomics examines how entities, forming a market structure , interact within a market to create a market system. These entities include private and public players with various classifications, typically operating under scarcity of tradable units and light government regulation. In theory, in a free market the aggregates sum of of quantity demanded by buyers and quantity supplied by sellers may reach economic equilibrium over time in reaction to price changes; in practice, various issues may prevent equilibrium, and any equilibrium reached may not necessarily be morally equitable. For example, if the supply of healthcare services is limited by external factors , the equilibrium price may be unaffordable for many who desire it but cannot pay for it.
Hayek Meets Information Theory. And Fails.
A major criticism of MADM is that different techniques may yield different results when applied to the same problem. The problem considered in this study consists of a decision matrix input of N criteria weights and ratings of L alternatives on each criterion. The comparative performance of some methods has been investigated in a few, mostly field, studies.

The effect of increasing competitor density on territorial defense shows that the fitness consequences to an individual of behaving in a particular way depend on the presence and activities of other animals of the same species. These relationships are examined… Classification of games Games can be classified according to certain significant features, the most obvious of which is the number of players.
Thus, a game can be designated as being a one-person, two-person, or n-person with n greater than two game, with games in each category having their own distinctive features. In addition, a player need not be an individual; it may be a nation, a corporation, or a team comprising many people with shared interests. In games of perfect information, such as chess , each player knows everything about the game at all times. The extent to which the goals of the players coincide or conflict is another basis for classifying games.
Constant-sum games are games of total conflict, which are also called games of pure competition. Poker, for example, is a constant-sum game because the combined wealth of the players remains constant, though its distribution shifts in the course of play. Players in constant-sum games have completely opposed interests, whereas in variable-sum games they may all be winners or losers.
In a labour-management dispute, for example, the two parties certainly have some conflicting interests, but both will benefit if a strike is averted. Variable-sum games can be further distinguished as being either cooperative or noncooperative. In cooperative games players can communicate and, most important, make binding agreements; in noncooperative games players may communicate, but they cannot make binding agreements, such as an enforceable contract. An automobile salesperson and a potential customer will be engaged in a cooperative game if they agree on a price and sign a contract.
However, the dickering that they do to reach this point will be noncooperative.
Messenger A two-page paper published by John Nash in is a seminal contribution to the field of Game Theory and of our general understanding of strategic decision-making. Such situations are pervasive in real life. The payoff for a buyer in an auction, for example, depends not only on the amount he bids but also on the bids of the other buyers. Likewise, the profit realised by a firm depends not only on the price it sets for its product but also on the prices set by its competitors.
They are non-cooperative because decision makers take their actions independently and are unable to enter into binding agreements with others regarding their actions, either because such agreements are illegal when setting prices or because they have no incentive to do so as in tennis.
Bargaining over Babies: Theory, Evidence, and Policy Implications. With Fabian Kindermann. Abstract: It takes a woman and a man to make a baby. This fact suggests that for a birth to take place, the parents should first agree on wanting a child.
The same interview includes an extensive discussion with vice president Ron Feldman as well, something I’ll cover in a later MoneyIllusion post. Kashkari is one of my favorite people at the Fed, and I agree with much of what he has to say. As usual, however, I’ll focus on the few points of disagreement. When I travel around my district and I talk about the Fed’s current framework, I get a lot of pushback on our 2 percent target.
I can only imagine the outcry if we were to try to raise it to 3 percent or 4 percent, number one. Number two, so far, we can’t even hit our 2 percent target.

In recent decades, the correlation between U. This changing correlation accounts for roughly 30 percent of the rise in the variance of male earnings between and In this paper, we rationalize these trends in a model of joint household labor supply. Our model is consistent with the observations that the changing wage-hours correlation among men is driven by married men, and that there is little change in the wage-hours correlation among employed women and at the household level.

Such a relationship makes intuitive sense: Building on Okun’s law, another economist, A. Phillips, discovered a relationship between unemployment and inflation. The chain of basic ideas behind this belief follows: In other words, Phillips showed that unemployment and inflation shared an inverse relationship: Since two major goals for economic policy makers are to keep both inflation and unemployment low, Phillip’s discovery was an important conceptual breakthrough, but also posed a troublesome challenge: The Phillips Curve Phillips’ discovery can be represented in a curve, called, aptly, a Phillips curve.
The Phillips Curve It is important to remember that the Phillips curve depicted above is simply an example. The actual Phillips curve for a country will vary depending upon the years that it aims to represent. Notice that the inflation rate is represented on the vertical axis in units of percent per year. The unemployment rate is represented on the horizontal axis in units of percent. The curve shows the levels of inflation and unemployment that tend to match together approximately, based on historical data.
As unemployment falls, inflation increases.
Economics Specializations The breadth of the potential real-world applications of economic knowledge is reflected in the vast range of specializations available at graduate level. You can choose to further your knowledge in a topic already covered in the introductory modules, or choose a new specialization to concentrate on. Below are some of the most commonly studied economics topics as every course will be different, keep in mind that the descriptions below are only an outline: By the end of your course, you may have conducted an independent piece of empirical research using advanced econometric techniques.
You will cover topics such as supply and demand, the operation of markets, consumer and enterprise behavior, competition and monopoly, income distribution, discrimination and consumer demand.

Introduction Despite 50 years of development experience, fundamental questions remain unanswered. A profusion of economic theories provide explanations for specific expressions of development, but none unite the pieces into a unified theory that adequately defines the central principles, process and stages of development. The formulation of a comprehensive theory of development would make conscious the world’s experience over the past years, reveal enormous untapped potentials and vastly accelerate the speed of future progress.
This paper is identifies the central principle of development and traces its expression in different fields, levels and stages of expression. Development is a function of society’s capacity to organize human energies and productive resources to respond to opportunities and challenges. The paper traces the stages in the emergence of higher, more complex, more productive levels of social organization through the historical stages of nomadic hunting, rural agrarian, urban, commercial, industrial and post-industrial societies.
It examines the process by which new activities are introduced by pioneers, imitated, resisted, accepted, organized, institutionalized and assimilated into the culture.

Theory of Development. by Garry Jacobs, Robert Macfarlane, and N. Asokan [presented to Pacific Rim Economic Conference, Bangkok, Jan , ].
History[ edit ] During the classical period of economics, microeconomics was closely linked to psychology. For example, Adam Smith wrote The Theory of Moral Sentiments , which proposed psychological explanations of individual behavior, including concerns about fairness and justice ,  and Jeremy Bentham wrote extensively on the psychological underpinnings of utility.
However, during the development of neo-classical economics economists sought to reshape the discipline as a natural science , deducing economic behavior from assumptions about the nature of economic agents. They developed the concept of homo economicus , whose psychology was fundamentally rational. However, many important neo-classical economists employed more sophisticated psychological explanations, including Francis Edgeworth , Vilfredo Pareto , and Irving Fisher.
Economic psychology emerged in the 20th century in the works of Gabriel Tarde ,  George Katona ,  and Laszlo Garai. Observed and repeatable anomalies eventually challenged those hypotheses, and further steps were taken by the Nobel Prize-winner Maurice Allais , for example, in setting out the Allais paradox , a decision problem he first presented in that contradicts the expected utility hypothesis.
Daniel Kahneman , winner of the Nobel Prize in economics In the s cognitive psychology began to shed more light on the brain as an information processing device in contrast to behaviorist models.
Nudge theory Richard Thaler , winner of the Nobel Prize in economics Nudge is a concept in behavioral science , political theory and economics which proposes positive reinforcement and indirect suggestions as ways to influence the behavior and decision making of groups or individuals. Nudging contrasts with other ways to achieve compliance, such as education , legislation or enforcement.
The concept has influenced British and American politicians. The first formulation of the term and associated principles was developed in cybernetics by James Wilk before and described by Brunel University academic D.
Behavioral economics studies the effects of psychological, cognitive, emotional, cultural and social factors on the economic decisions of individuals and institutions and how those decisions vary from those implied by classical theory.. Behavioral economics is primarily concerned with the bounds of rationality of economic agents. Behavioral models typically integrate insights from psychology.
What do you think? The past decade has been a triumph for behavioural economics, the fashionable cross-breed of psychology and economics. First there was the award in of the Nobel Memorial Prize in economics to a psychologist, Daniel Kahneman — the man who did as much as anything to create the field of behavioural economics. Bestselling books were launched, most notably by Kahneman himself Thinking, Fast and Slow , and by his friend Richard Thaler, co-author of Nudge Behavioural economics seems far sexier than the ordinary sort, too: Behavioural economics is one of the hottest ideas in public policy.
Behavioral economics under attack.
In practical terms, this will translate into more cautious policy advice — and a reduced willingness to dismantle economic safeguards in the faith that markets will solve all problems. Over the next years an extensive body of economic theory was developed, whose central message was: This faith was, however, shattered by the Great Depression.
The Theory of Interstellar Trade Paul Krugman∗ June 20, Editor’s note: This article was written in July but has not been previ-ously published.
The main problem is simpliciter that there is no such thing as a Keynes-Hicks macroeconomic theory! So, let us get some things straight. And it gets even worse! I accordingly conclude that the only way in which IS-LM analysis usefully survives — as anything more than a classroom gadget, to be superseded, later on, by something better — is in application to a particular kind of causal analysis, where the use of equilibrium methods, even a drastic use of equilibrium methods, is not inappropriate.
I am quite prepared to believe that there are cases where he is entitled to overlook them. But the issue is one which needs to be faced in each case. When one turns to questions of policy, looking toward the future instead of the past, the use of equilibrium methods is still more suspect. For one cannot prescribe policy without considering at least the possibility that policy may be changed.
There can be no change of policy if everything is to go on as expected-if the economy is to remain in what however approximately may be regarded as its existing equilibrium. It may be hoped that, after the change in policy, the economy will somehow, at some time in the future, settle into what may be regarded, in the same sense, as a new equilibrium; but there must necessarily be a stage before that equilibrium is reached … I have paid no attention, in this article, to another weakness of IS-LM analysis, of which I am fully aware; for it is a weakness which it shares with General Theory itself.
