An arbiter can decide a case on the basis of his priors, or the two parties to the conflict may present further evidence. The parties may misrepresent evidence in their favor at a cost. At equilibrium the two parties never testify together. When the evidence is much in favor of one party, this...

Domains of individual preferences for which the well-known impossibility Theorems of Gibbard-Satterthwaite and Muller-Satterthwaite do not hold are studied. First, we introduce necessary and sufficient conditions for a domain to admit non-dictatorial, Pareto efficient and either strategy-proof...

The closed economy neoclassical model predicts lung-run convergence in per-capita income. We show, within a neoclassical framework, that international trade among two countries differing only in their initial capital endowment generates long-run income differences. Our results suggests that...

Chari, Kehoe, and McGrattan (2007) (CKM) show that a large class of dynamic stochastic general equilibrium (DSGE) models with various frictions and shocks is observationally equivalent to a benchmark real business cycle (RBC) model with correlated 'wedges' in the RBC model's first-order...

We propose a method to incorporate information from Dynamic Stochastic General Equilibrium (DSGE) models into Dynamic Factor Analysis. The method combines a procedure previously applied for Bayesian Vector Autoregressions and a Gibbs Sampling approach for Dynamic Factor Models. The factors in...

This paper presents a positive model which shows that institutional setups on capital and labor markets might be intertwined by politicoeconomic forces. Some countries especially in continental Europe exhibit a corporatist politicoeconomic equilibrium with a sustantial protection of insiders on...

The paper examines of the division of labor within firms. It provides an explanation of the pervasive observed changes in work organisation away from the traditional functional departments and towards multi-tasking and job rotation. Whereas the exsisting literature on the division of labour...

This paper provides a theoretical and numerical analysis of robust hedging strategies in diffusion?type models including stochastic volatility models. A robust hedging strategy avoids any losses as long as the realised volatility stays within a given interval. We focus on the effects of...

When options are traded, one can use their prices and price changes to draw inference about the set of risk factors and their risk premia. We analyze tests for the existence and the sign of the market prices of jump risk that are based on option hedging errors. We derive a closed-form solution...
