Standard economic wisdom generally stresses the benefits of increased competition on the product market. This paper proposes a model of monopolistic competition with an endogenous determination of workers flows in and out of unemployment, where wages are determined according to an efficiency...

Environmental policies frequently target the ratio of dirty to green output within the same industry. To achieve such targets the green sector may be subsidised or the dirty sector be taxed. This paper shows that in a monopolistic competition setting the two policy instruments have different...

Standard economic wisdom generally stresses the benefits of increased competition on the product market. This paper proposes a model of monopolistic competition with an endogenous determination of workers flows in and out of unemployment, where wages are determined according to an efficiency...

We present a natural generalization of the Dixit-Stiglitz monopolistic competition model (DSM) | we assume that there is a continuum of industries, each of them described as in DSM, and each characterized with its own elasticity of substitution. Although rms in all industries share the same...

Using an endogenous growth model with physical and human capital accumulation, this paper considers the sustainability of economic growth when the use of a polluting input (e.g., fossil fuels) intensifies the risk of capital destruction through natural disasters. We find that growth is...

We analyze the steady state and transitional dynamics of two-sector model with structural change and horizontal innovation. There are three main economic forces could drive structural change: technological progress in one sector, technological progress in the other sector, and capital deepening....

This paper provides the complete closed-form solution to the Lucas two-sector model of endogenous growth. We study the issues of existence, uniqueness, multiplicity, positivity, transitional dynamics and long-run growth, related to the competitive equilibrium paths. We identify the parameter...

This paper considers transitional dynamics of a two-sector endogenous growth model in the Uzawa-Lucas framework. We find that when the ratio of physical to human capital is sufficiently high, it is optimal for both consumption and physical capital to fall for a finite period and then gradually...

We develop a product-differentiated model where the product space is a network defined as a set of varieties (nodes) linked by their degrees of substitutability (edges). We also locate consumers into this network, so that the location of each consumer (node) corresponds to her "ideal" variety....
