A framework is developed in which the formation of gangs --- the criminal market structure --- is endogenous. We examine the impact of crime deterrence in this framework. It is shown that for a given gang structure, an increase in deterrence reduces criminal output. However, under identifiable...

Empirical studies reveal that monetary policy shocks generate long-lasting effects on real GDP, countercyclical real wages before World War II and procyclical real wages afterwards. In this paper, we construct a dynamic general equilibrium model to explain the observed output persistence and the...

Multi-country models have not been very successful in replicating important features of the international transmission of business cycles. This paper extends previous work by introducing multiple sectors and traded intermediate inputs. Trade in intermediate goods represents approximately 60% of...

Why do democratic societies often impose legal restrictions that render various assets or entitlements inalienable, thereby limiting the disposable property rights of individuals? The explanation proposed here is that these constraints arise as an institutional response against private debt...

We examine whether minimum wages can fulfill a useful role as part of an optimal non-linear income tax scheme. In this setting, governments cannot observe household abilities, only their incomes. Redistributing according to income, the government is constrained by a set of incentive constraints....

The paper analyzes optimal fiscal policy in an overlapping generations model with two-period lived households. The government must choose tax rates and borrowing to finance an exogenous stream of expenditures. It cannot commit to future policies, so announced policies that are not time...

Using aggregate US and Canadian data, this paper examines the implications for the empirical assessment of market structure and exogeneity of productivity shocks of correcting the Solow residual for variation in capacity utilization. In contrast to most studies, not accounting for capacity...

The purpose of this paper is to use a game theoretical approach to analyze tax harmonization, or competition, in a monetary union, more specifically in Europe. Without harmonization, free-riding behaviors may appear, leading to a sub-optimal tax equilibrium. Tax competition may also create...

Welfare programs including disability benefits have been considered as an efficient way of delivering transfers to the needy. This paper addresses the importance of administrative cost of welfare systems by focusing on an agency problem arising between the government and social workers, whose...

A semiparametric efficient estimation procedure is developed for the parameters of multivariate GARCH-in-mean models when the disturbances have a distribution that is assumed to be elliptically symmetric but is otherwise unrestricted. Under high level restrictions, the resulting estimator...
