This paper examines an economic union where oligopolistic firms produce by skilled and unskilled labor and do in-house R&D by skilled labor. The planner of the union accepts new members to the union, regulates the labor market through a minimum wage for unskilled labor and supports firms by...

We examine a common market which expands by integrating new regions. Capitalists are strategically interdependent through the goods market and they improve their productivity through R&D. Production and R&D employ unionized workers. The purpose of integration is to maximize a weighed average of...

This paper examines an economy with a large number of industries, each producing a different good. Technological change follows a Poisson process where firms improve their productivity through investment in R&D. The less there are firms in the economy or the more they can coordinate their...

The effects of competition on growth are analyzed in the recent literature by comparing economies with the same market structure but different degrees of substitutability. In this note, we show that in a general equilibrium model with monopolistic competition à la Dixit- Stiglitz the effect of...

One of the predictions of the insider-outsider theory is that wages will be higher in sectors (firms) with high labor adjustment costs/high turnover costs. This prediction is tested empirically in this study, using an insider-outsider model and a longitudinal panel of large firms in Portugal....

Anecdotal, empirical, and experimental evidence suggests that offering extrinsic rewards for certain activities can reduce people's willingness to engage in those activities voluntarily. We propose a simple rationale for this 'crowding out' phenomenon, using standard economic arguments. The...

This paper extends Hall's (1988) methodology to analyse imperfections in both the product and the labour market for firms in the Belgian manufacturing industry over the period 1988- 1995. We investigate the heterogeneity in price-cost mark-up and workers' bargaining power parameters among 18...
