The standard approach to modelling consumption/saving problems is to assume that the decisionmaker is solving a dynamic stochastic optimization problem However under realistic descriptions of utility and uncertainty the optimal consumption/saving decision is so difficult that only recently...

Price dynamics are characterized when a price-fixing cartel is concerned about creating suspicions of the presence of a cartel A dynamical extension of static models yields the counterfactual prediction that the cartel initially raises price and then gradually lowers it An alternative...

This paper introduces a method for solving numerical dynamic stochastic optimization problems that avoids rootfinding operations. The idea is applicable to many microeconomic and macroeconomic problems, including life cycle, buffer-stock, and stochastic growth problems. Software is provided.

Although there exist learning processes for which the empirical distribution of play comes close to Nash equilibrium it is an open question whether the players themselves can learn to play equilibrium strategies without assuming that they have prior knowledge of their opponents' strategies...

We derive necessary and suffcient conditions for simple monetary policy rules that guarantee equilibrium determinacy in the New Keynesian monetary model. Our modeling framework is derived from a fully specified optimization model that is still amenable to analytical characterisation. The...

This paper investigates efficiency losses caused by independent tax systems and proposes ways of remedying this coordination failure Whereas the harmful effects of tariff competition have been thoroughly explored in the trade policy literature little is known about the externalities that result...

This paper presents a new stage-of-fabrication inventory model with ordering usage and stocking of input materials that distinguishes between gross production and value added It extends the traditional linear-quadratic model of output (finished goods) inventories by adding joint determination of...

We demonstrate the possibility of indeterminacy and non-existence of equilibrium dynamics in a standard business cycle model with search and matching frictions in the labor market. Our results arise for empirically plausible parametrizations and do not rely upon a mechanism such as increasing...
