In this paper we address the control problem of a social optimum in presence of waste and capital stocks. We address this problem in two stages. In the first, we suppose that output is fixed; next, we endogenize output allowing for growth. The analytical framework is simple. Consumption is assumed...

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...

In this paper we address the question whether fiscal incentives and regulation are the most appropriate tools to increase productivity in energy sector. Doubts exist about whether these are the most effective tools for improving productivity since changes in productivity are usually related to...

In this paper I study the e¤ects of environmental regulation which establishes upper and lower binding targets to pollution emissions. Essentially, I deal with the properties of a stochastic model of pollution control in continuous-time under emission targets and uncertainty, emphasizing...

In this paper we present a continuous time model with reversible abatement capital in order to analyze the effects of environmental policies on the value of the firm and investment decisions. We show that the effects depend on what sort of future policy are implemented. We focus on investment...

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 address the question whether the shift in labour supply curve is the only fundamental change capturing the negative correlation between the growth rates of productivity and employment in European countries in the last fifteen years. If this explanation is correct then the labour...

In what follows, we show that financing constraints affects firm's investment decisions before the constraints is binding. This occurs because the firm anticipates at the current time the future bound. We argue that, even with imperfect capital markets, investment policy must be such that there...
