Previous literature demonstrates that in a standard life cycle model the optimal tax on capital is large. This paper highlights that after changing two assumptions in the standard model the optimal tax drops by almost half. First, the utility function is altered such that it implies that an...

In life-cycle economies, where an individual's optimal consumption-work plan is almost never constant, the optimal marginal tax rates on capital and labor income vary with age. Conversely, the progressivity imbedded in the U.S. tax code implies that marginal tax rates vary with age because tax...

This paper characterizes long-run and short-run optimal fiscal policy in the labor selection framework. In a calibrated non-Ramsey decentralized equilibrium, labor market volatility is inefficient. Keeping fixed the structural parameters, the Ramsey government achieves efficient labor market...

This paper studies implementation of the social optimum in a model of addictive consumption. We consider corrective taxes that address inefficiencies due to negative externalities, imperfect competition, and self-control problems. Our setup allows us to evaluate how such taxes are affected by...

We propose a method for solving and estimating linear rational expectations models that exhibit indeterminacy and we provide step-by-step guidelines for implementing this method in the Matlab-based packages Dynare and Gensys. Our method redefines a subset of expectational errors as new...

We propose an agent-based computational model to investigate sequential Dutch auctions with particular emphasis on markets for perishable goods and we take as an example wholesale fish markets. Buyers in these markets sell the fish they purchase on a retail market. The paper provides an original...

We develop an agent-based model in which heterogeneous and boundedly rational agents interact by trading a risky asset at an endogenously set price. Agents are endowed with balance sheets comprising the risky asset as well as cash on the asset side and equity capital as well as debt on the...

We propose a double auction mechanism for the exchange of leveraged assets and bonds in an agent based model. In this framework we validate recent results in general equilibrium theory about endogenous leverage and its consequences for asset pricing. We find that the institutional details of...

The problem of computing equilibria for general equilibrium models with incomplete real asset markets, or GEI models for the sake of brevity, is reconsidered. It is shown here that the rank-dropping behavior of the asset return matrix could be dealt with in rather a simple fashion: We first...

What is the most appropriate combination of fiscal and monetary policies in economies subject to banking crises and deep recessions? We study this issue using an agent-based model that is able to reproduce a wide array of macro- and micro-empirical regularities. Simulation results suggest that...
