45 An answer to these puzzles was proposed by Shapiro and Stiglitz in 1984: "Unemployment is driven by the information structure of employment". 45 Two basic observations undergird their analysis: Unlike other forms of capital, humans can choose their level of effort. It is costly for firms to determine how much effort workers are exerting. A full description of this model can be found at the links provided. 46 47 Some key implications of this model are: Wages do not fall enough during recessions to prevent unemployment from rising. If the demand for labour falls, this lowers wages.

This balance will differ from time to overpopulation time and place to place. In an interview in mountain 2007, Stiglitz explained further: 42 The theories that I (and others) helped develop explained why unfettered markets often not only do not lead to social justice, but do not even produce efficient outcomes. Interestingly, there has been no intellectual challenge to the refutation of Adam Smith's invisible hand: individuals and firms, in the pursuit of their self-interest, are not necessarily, or in general, led as if by an invisible hand, to economic efficiency. The preceding claim is based on Stiglitz 1986 paper, "Externalities in Economies with Imperfect Information and Incomplete markets 38 which describes a general methodology to deal with externalities and for calculating optimal corrective taxes in a general equilibrium context. In the opening remarks for his prize acceptance at Aula magna, 43 Stiglitz said: 44 I hope to show that Information Economics represents a fundamental change in the prevailing paradigm within economics. Problems of information are central to understanding not only market economics but also political economy, and in the last section of this lecture, i explore some of the implications of information imperfections for political processes. Shapiro-Stiglitz efficiency wage model edit main article: ShapiroStiglitz theory see also: Efficiency wages In the Shapiro-Stiglitz model of efficiency wages, workers are paid at a level that dissuades shirking. This prevents wages from dropping to market clearing levels. Full employment cannot be achieved because workers would shirk if they were not threatened with the possibility of unemployment. Because of this, the curve for the no-shirking condition (labeled nsc) goes to infinity at full employment. Stiglitz also did research on efficiency wages, and helped create what became known as the "Shapiro-Stiglitz model" to explain why there is unemployment even in equilibrium, why wages are not bid down sufficiently by job seekers (in the absence of minimum wages) so that everyone.
Stiglitz has shown (together with Bruce Greenwald ) that "whenever markets are incomplete and/or information is imperfect (which are true in virtually all economies even competitive market allocation is not constrained Pareto efficient ". In other words, they addressed "the problem of determining when tax interventions are pareto-improving. The approach indicates that such tax interventions almost always exist and that equilibria in situations of imperfect information are rarely constrained Pareto optima." 38 :229, abstract Although these conclusions and the pervasiveness of market failures do not necessarily warrant the state intervening broadly in the. 39 For Stiglitz, there is no such thing as an invisible hand, in the sense that free markets lead to efficiency as if guided by unseen forces. 40 According to Stiglitz: 41 Whenever there are "externalities" where the actions of an individual have impacts on others for paper which they do not pay or for which they are not compensated markets will not work well. But recent research has shown that these externalities are pervasive, whenever there is imperfect information or imperfect risk markets that is always. The real debate today is about finding the right balance between the market and government. They can each complement each other.
Stiglitz dubbed this the ' henry george theorem ' in reference to the radical classical economist Henry george who famously advocated for land value tax. The explanation behind Stiglitz's finding is that rivalry for public goods takes place geographically, so competition for access to any beneficial public good will increase land values by at least as much as its outlay cost. Furthermore, stiglitz shows that a single tax on rents is necessary to provide the optimal supply of local public investment. Stiglitz also shows how the theorem could be used to find the optimal size of a city or firm. 36 37 Information asymmetry edit Stiglitz's most famous research was on screening, a technique used by one economic agent to extract otherwise private information from another. It was for this contribution to the theory of information asymmetry that he shared the nobel Memorial Prize in Economics 18 in 2001 "for laying the foundations for the theory of markets with asymmetric information " with george. Before the advent of models of imperfect and asymmetric information, the traditional neoclassical economics literature had assumed that markets are efficient except for some limited and well defined market failures. More recent work by Stiglitz and others reversed that presumption, to assert that it is only under exceptional circumstances that markets are efficient.

Contributions to economics edit Stiglitz at a conference in Mexico in 2009 Risk aversion edit After getting his PhD from. I.T in 1967, Stiglitz co-authored one of his first papers with Michael Rothschild for the journal of Economic Theory in 1970. 34 Stiglitz and Rothschild extrapolated on previous works by prominent economists such as Robert Solow to work on the concept of risk aversion, which is the behavior in humans to lower the uncertainty presented in the risk situation. Stiglitz and Rothschild's paper's primary focus was on defining "When is a random variable 'y' more variable than another random variable 'x'." In this mathematically complex paper, Stiglitz and Rothschild showed four plausible answers to this question, which led them to write the second paper. 35 They examine an individual's return on savings, portfolio problem, portfolio-savings problem and a firm's production problem. These papers allowed Stiglitz to earn the john Bates Clark medal in 1979. Henry george theorem edit Stiglitz made early contributions to a theory of public finance stating that an optimal supply of local public goods can be funded entirely through capture of the land rents generated by those goods (when population distributions are optimal).
