In order to simplify the representation of a technological relationship between inputs and outputs, a production unit's technology must typically satisfy some restrictive conditions, some of them being well known in the literature. This paper presents new results for aggregating labour inputs...

This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the...

In this paper we conduct a theoretical analysis of the implications of a union which can exploit the existence of firm labour adjustment costs. We consider a model involving a large number of identical firms facing a single, economy-wide union. We solve (i) for the Markov perfect equilibria with...

This paper uses a two country trade and geography model of monopolistic competition to study the effects of wage policies and social policies on the location of industry. It is first shown that a union wage push in one of two otherwise identical countries induces a relocation of firms which...

The model of compensating differentials in regional labor markets was developed by Roback (1982). The model interprets regional differences in constant quality wages and rents as compensating firms and residents for inter-regional differences in amenities. The model assumes that the costs of...

The process leading to the setting of the minimum wage so far has been fairly overlooked by economists. This paper suggests that this is a serious limitation as the setting regime contributes to explain cross-country variation in the fine-tuning of the minimum wage, hence in the way in which the...

The optimal mix of growth policies is derived within a comprehensive endogenous growth model. The analysis captures important elements of the tax-transfer system and takes into account transitional dynamics. Currently, for calculating corporate taxable income US firms are allowed to deduct...

This paper studies the social desirability of agglomeration and the efficiency arguments for policy intervention in a simple, analytically solvable ?new economic geography? model with two trade integrating regions. The location pattern emerging as market equilibrium is ?bubbleshaped?, i.e. it...

It is now a commonplace that the unfunded public pension systems of many OECD countries will run into severe financing problems in the coming decades due to a dramatically increasing pensioner/worker ratio. While this diagnosis is completely undisputed, there is still a vigorous debate on the...

According to the compensation theory, market forces should assure a complete compensation of the initial labour-saving impact of process innovations. In this paper a critique of this approach is proposed through a detailed survey of the theoretical and empirical literature on the subject. The...
