Heterogeneity between unemployed and employed individuals matters for optimal fiscal policy. This paper considers the consequences of such heterogeneity for the determination of optimal capital and income taxes in a model with matching frictions in the labor market. In line with a recent finding...

This paper focuses on the role of government capital as a critical productive input when the level of services that the agent derives from it is subject to congestion. I develop a two-sector “non-scale†production model in which there are two types of firms, conventional...

In the last half of the 1990s, labor productivity growth rose in the U.S. and fell almost everywhere in Europe. We document changes in both capital deepening and multifactor productivity (MFP) growth in both the information and communication technology (ICT) and non-ICT sectors. We view MFP...

This paper presents a multiregion modeling approach focussing on capital mobility and spillovers. The approach is based on a Ramsey type economic growth model, on the one hand, and on the balance of payment concept, on the other hand. The way to find an equilibrium solution is novel. It differs...

We study the technological pre-conditions for competitive equilibrium in a multisectoral economy where"land" is an essential imput. Earlier results by Bidard and Salvadori require either very low interest rates or are unable to predict the type of final demand vectors that can be supported by an...

Solow and Hahn proposed an overlapping generations model in 1995 with which to criticize rational expectations. The agents have perfect foresight, but are subjected to an unanticipated shock in the population. The authors showed that the economy couldn't return to the steady state without...

Over the years, optimal taxation has been extensively discussed, and a major focus has been on the question of whether the optimal capital income tax rate is zero in long-run equilibrium. This paper addresses this issue in the context of a model of vintage capital with technical change and the...

This paper studies how international capital mobility affects aggregate volatility by considering the case of imperfect financial markets such that only physical capital serves as collateral for international borrowing, whereas human capital cannot. We find that credit-rationed, small open...

The choice between private and government provision of a productive public good like infrastructure (public capital) is examined in the context of an endogenously growing open economy. The accumulation of public capital need not require government provision, in contrast to the standard...
