In this paper, the expansion of private production erodes the quality of commonly owned goods, thereby forcing individuals to rely increasingly on private goods to satisfy their needs. In the face of this deterioration, households keep their labour supplies and saving rates relatively high in...

A model of ecologically sustainable endogenous growth is presented, in which environmental quality has a positive influence on individual welfare and on the productivity of capital. The effect of different environmental policies on the long-run growth of the economy is studied in the framework...

In this paper we build an endogenous growth model where human capital and ideas are complements in the long-run equilibrium and technological progress takes the form of a continuous increase in the number of horizontally differentiated varieties of intermediate inputs. One peculiarity of the...

Using a vertical differentiation model of endogenous growth with stochastic R&D activity, we characterise the optimal patent lifetime a government would set in order to maximise economic growth. We show that a finite patent lifetime does exist and is unique provided that the expected rate of...

This paper analyses environmental fiscal policy within a two-sector endogenous growth model with elastic labour supply. Pollution is modelled as a side product of production. The framework allows us to analyse the consequences of an environmental tax on the economic dynamics. Both transitional...

In this paper we study two closely related issues. First, the role of technology heterogeneity and diffusion in the convergence of GDP per worker observed across the European regions, in the absence of data on regional TFP. Second, the spatial pattern of the observed regional heterogeneity in...

We present an optimal endogenous growth model with an environmental asset which delivers a direct social utility value. The efficiency of the production services provided by the environmental asset directly depend on past capital accumulation. Such an assumption corresponds to assuming that past...

This article studies the implications of consumption taxation on capitalaccumulation in a one-sector endogenous growth model with finite horizons. A tax on consumption, when tax revenues are lump-sum rebated to consumers, redistributes income between living generations and future, still unborn,...

We present a growth model in which R&D increases productivity, union-firm bargaining determines the distribution of rents and the government can support unions by labour market regulation. We show that if unions are initially very strong, regulation increases only the workers? profit share and...

If redistribution is distortionary, and if the income of skilled workers is due to knowledgeintensive activities and depends positively on intellectual property, a social planner which cares about income distribution may in principle want to use a reduction in Intellectual Property Rights (IPRs)...
