There is a robust literature on the relationship between financing constraints and real investment. Little has been said on the relationship between financing constraints and capital stock in the long run. This note focuses on this last issue. To keep the model tractable, we assume that the firm...

In this paper we investigate the effects of introducing explicitly abatement capital in a welfare function which depends on waste stock and consumption. Consumption is assumed to produce an undesiderable residue. Society can control waste accumulation using abatement capital. We focus on two...

In this paper, we study the effects of environmental regulation which establishes binding targets to pollution accumulation. Pollution follows a geometric Brownian motion. Inside the targets, pollution behaves as if it were freely floating until it hits one of the two limits. The model provides...

In this paper we present a simple model of university-industry collaborations with heterogeneous agents, which is the standard case of technology transfer. We study the characteristics of the matching process, that makes this exchange in technology transfer either efficient or unfeasible. We...

This paper aims at analyzing labor productivity per hour worked in the manufacturing industries of four industrialized countries, Germany, France, Italy and the U.S., between 1950 and 2010. It uses the common trends - common cycles approach to decompose series into trends and cycles. We find...
