We analyze the welfare properties of the equilibrium path of a growth model where both habits and consumption externalities affect the utility of consumers. Our analysis highlights the crucial role played by complementarities between externalities and habits in order to generate an inefficient...

This paper analyses the e¤ects on employment of increasing the stock of public capital. To this end, we derive a wage equation so that wages are endogenized. This allows us to show that, by means of a higher elasticity of labour demand with respect to wages, a rise in public capital increases...

We develop a growth model with unemployment due to imperfections in the labor market. In this model, wage inertia and balanced budget rules cause a complementarity between capital and employment capable of explaining the existence of multiple equilibrium paths. Hysteresis is viewed as the result...

In this paper, we show that consumption externalities are a source of equilibrium indeterminacy in a growth model with endogenous labor supply. In particular, when the marginal rate of substitution between own consumption and the others' consumption is constant along the equilibrium path, the...

In this paper we derive the general framework for growth models with non competitive labor and output markets and disequilibrium unemployment. For the three standard ways of generating savings, the framework makes clear how capital growth depends on employment and employment on the stock of...

We analyze the welfare properties of the competitive equilibrium in a capital accumulation model where individual preferences are subject to both habit formation and consumption spillovers. Using an additive specification for preferences, according to which the argument in the utility function...

When habits are introduced multiplicatively in a capital accumulation model, the consumers' objective function might fail to be concave. In this paper we provide conditions aimed at guaranteeing the existence of interior solutions to the consumers' problem. We also characterize the equilibrium...

We analyze the welfare properties of the competitive equilibrium in a capital accumulation model where individual preferences are subjected to both habit formation and consumption spillovers. We also discuss how consumption externalities and habits interact to generate an inefficient dynamic...

The purpose of this paper is to introduce a noncompetitive labor market and unemployment into the growth models with exogenous saving rates found in economic growth textbooks (SalaiMartin, 2000; Barro and SalaiMartin, 2003; Romer, 2006). We first derive a general framework with a neoclassical production...
