This paper investigates, in a simplified macro context, the joint determination of the (incorrect) perceived model and the equilibrium. I assume that the model is designed by a self-interested economist who knows the true structural model, but reports a distorted one so as to influence outcomes....

When asked to name one proposition in the social sciences that is both true and non-trivial, Paul Samuelson famously replied: 'Ricardo's theory of comparative advantage'. Truth, however, in Samuelson's reply refers to the fact that Ricardo's theory of comparative advantage is mathematically...

Neither economics nor political science can explain the process of modern social development. The fact that developed societies always have developed economies and developed polities suggests that the connection between economics and politics must be a fundamental part of the development...

Theoretical advances in macroeconomics made in the last three decades have had a major influence on macroeconomic policy analysis. Moreover, over the last several decades, the United States and other countries have undertaken a variety of policy changes that are precisely what macroeconomic...

For a long while after the explosion of macroeconomics in the 1970s, the field looked like a battlefield. Over time however, largely because facts do not go away, a largely shared vision both of fluctuations and of methodology has emerged. Not everything is fine. Like all revolutions, this one...

We identify three separate stages in the post-World War II history of applied microeconomic research: A generally non-mathematical period; a period of consensus (from the 1960s through the early 1990s) characterized by the use of mathematical models, optimization and equilibrium to generate and...

Although many economists, most notably Strotz, have discussed dynamic inconsistency and precommitment, none have dealt directly with the essence of the problem: self-control. This paper attempts to fill that gap by modeling man as an organization. The Strotz model is recast to include the...

This essay examines the idea and potential of a computational approach to theory,' discusses methodological issues raised by such computational methods, and outlines the problems associated with the dissemination of computational methods and the exposition of computational results. We argue that...

What determines the intensity and objects of hatred? Hatred forms when people believe that out-groups are responsible for past and future crimes, but the reality of past crimes has little to do with the level of hatred. Instead, hatred is the result of an equilibrium where politicians supply...

We propose an economic theory of addiction based on the premise that cognitive mechanisms such as attention affect behavior independently of preferences. We argue that the theory is consistent with foundational evidence (e.g. from neurosciencee and psychology) concerning the nature of...
