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 we develop a model of pollution control which maximizes the present value of net social benefits. We show that the presence of an upper constraint on emissions affects the pollution control even when emissions are far below the level where the constraint binds. We get three main...

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 argue that energy efficiency and environmental efficiency are two aspects of the same problem. To show this, we assess the analytical utility of the well-known IPACT and ImPACT models, presenting here a new developed identity named Augmented ImPACT. For Italy, our findings...

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 shed lights on the economic growth of Mezzogiorno of Italy during the last twenty years. The empirical analyses refer to various aspects of the Mezzogiorno economy: income per capita, labor productivity, public and private accumulation and competitiveness. The main contribution...

This is a short survey on consumption theory. Consumption is important to both fluctuation and growth. In addition, consumption introduces some important issues involving financial markets and portfolio decisions. We will describe consumption decisions in a dynamic context. Uncertainty about...

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...
