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 investigates whether and in what sense the west German wage structure has been ?rigid? in the 1990s. To test the hypothesis that a rigid wage structure has been responsible for rising low-skilled unemployment, I propose a methodology which makes less restrictive identifying...

The question of the allocation of public R&D funding is becoming particularly important when it comes to identifying the effects of state subsidies, in terms of input or output additionality. This analysis goes one important step further than the existing literature by including the time...

This paper looks at which firms receive R&D project grants and how this public support evolves over time by considering in particular firm's previous participation. The question of the allocation of public R&D funding is becoming particularly important when it comes to identifying the effects of...

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...

It is widely believed that rent-sharing reduces the incentives for investment when long term contracts are infeasible because some of the returns to sunk capital are captured by workers. We propose a simple test for the degree of hold-up based on the fraction of capital costs that are deducted...

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...
