I study the constrained efficient allocations of a simple model of risk sharing and capital flows across countries assuming that each country cannot commit to fully repay its contract obligations. In the model, the degree of risk sharing and the amount of investment are interdependent. It is...

This Paper investigates the relationship between risk and productive activity and the degree of financial intermediation in a model with moral hazard. Entreprenuers can simultaneously get credit from two types of competing institutions: ‘financial intermediaries’ and ‘local lenders’. The...

The most fundamental solution concepts in Game Theory – Nash equilibrium, backward induction, and iterated elimination of dominated strategies – are based on the assumption that people are capable of predicting others' actions. These concepts require people to be able to view the game from...

After fifty years of catching up to the US level of productivity, since 1995 Europe has been falling behind. The growth rate in output per hour over 1995-2003 in Europe was just half that in the United States, and this annual growth shortfall caused the level of European productivity to fall...

This paper analyzes the early research performance of PhD graduates in labor economics, addressing the following questions: Are there major productivity differences between graduates from American and European institutions? If so, how relevant is the quality of the training received (i.e....

This book provides a rigorous course to the theory of intermediate microeconomics. It includes not only the basic traditional theory, but also a ¡°From the Literature¡± box in each chapter directing students to applications of the theory. The theory is developed axiomatically, with optional...

Quantitative measures of research output, especially bibliometric measures, have not only been introduced within research funding systems in many countries, but they are also increasingly used in the media to construct rankings of universities, faculties and even individual scientists. In almost...

Loss aversion is one of the most robust findings to have emerged from behavioral economics. Surprisingly little attention, however, has been devoted to nominal loss aversion, the interaction of loss aversion and money illusion. People tend to think of transactions in terms of their nominal...

In many economics programs, both graduate students and new assistant professors are thrown into the classroom without guidance, with the potential for negative ramifications that can last throughout their careers as teachers. This article is a primer in which we offer unique insights into useful...

Reich (2013) recapitulates my model (Helmedag 2012a) incorrectly. Above all, he mixes up exogenous with endogenous variables. Moreover, Reich's interpretation of the system's dynamics is on the one hand formally insufficient; on the other hand, matters are presented in a more complicated way...
