The existence of an exact Walrasian equilibrium in nonconvex economies is still a largely unexplored issue. This paper shows that such an equilibrium exists in nonconvex economies by following the nearby economyapproach introduced by Postlewaite and Schmeidler (Approximate Walrasian Equilibrium...

We study the design of mechanisms that implement Lindahl or Walrasian allocations and whose Nash equilibria are dynamically stable for a wide class of adaptive dynamics. We argue that supermodularity is not a desirable stability criterion in this mechanism design context, focusing instead on...

Motivated by the problems of the conventional model in rationalizing market data, we derive the equilibrium interest rate and risk premiums using recursive utility in a continuous-time model. We use the stochastic maximum principle to analyze the model. This method uses forward/backward...

We consider a sovereign wealth fund that invests broadly in the international financial markets. The influx to the fund has stopped. We adopt the life cycle model and demonstrate that the optimal spending rate from the fund is significantly less than the fund's expected real rate of return. The...

Die Liberalisierung der globalen Finanzmärkte hat ihr Ziel verfehlt, für mehr Stabilität und Wirtschaftswachstum zu sorgen. Stattdessen folgt seit 30 Jahren eine Krise auf die andere. Jetzt werden etliche Bankenreformen diskutiert, um die Finanzmärkte krisensicherer zu machen. Dabei...

Forschungsergebnisse aus den letzten Jahren zeigen: Renditen von so genannten 'Sin Stocks', das heißt Aktien von Unternehmen, die aus Sicht der Investoren moralisch verwerflichen Tätigkeiten nachgehen, sind durchschnittlich höher als Renditen anderer Unternehmen. Aber warum gibt es hier einen...

The distributions of income and wealth in countries across the world are found to possess some robust and stable features independent of the specific economic, social and political conditions of the countries. We discuss a few physics-inspired multi-agent dynamic models along with their...

Traditionally, observed fluctuations in aggregate economic time series have been mainly modeled as being the result of exogenous disturbances. A better understanding of macroeconomic phenomena, however, surely requires looking directly at the relations between variables that may trigger...

This paper formulates equilibrium concepts in the large (non atomic) household model under the team notion, characterizes a class of equilibrium allocations, explores whether an equilibrium allocation in the large-household model is a limit of equilibrium allocations in the finite-household...
