We analyze the impact of obsolescence of economic inventions by incorporating maintenance costsin the endogenous growth model of expanding product varieties. This contrasts with the existingliterature, which ignores maintenance costs and uses the model of quality improvements todescribe...

Which signals are important in gaining attention in science? For a group of 1,371 scientific articles published in 17 demography journals in the years 1990-1992 we track their influence and discern which signals are important in receiving citations. Three types of signals are examined: the...

This paper is dating from 1995, when it has been presented at the Ragnar Frisch Centennial Memorial Conference in Oslo. It has never been published before.In this paper for the first time the Cantril ladder question data have been employed in the way which later has become known as happiness...

This paper conducts the first general equilibrium analysis of the role of entry, exit and profits in industry dynamics. The benefit of our model is twofold. First, to discriminate between entrants’ role of performing the entrepreneurial function of creating disequilibrium and the conventional...

The main contribution of entrepreneurship theory to economics is to provide an account of market performance in disequilibrium but little empirical research has examined firm entry and exit in this context. We redress this by modelling the interrelationship between firm entry and exit in...

This paper examines the relationship between organization contextual variables and humanresource management (HRM) practices in small firms. The proposed model is based on anintegration of theoretical perspectives, including the resource-based approach, institutionaltheory, transaction cost...

We study the effects of competition in a context in which people's actions can not be contractually fixed. We find that in such an environment the very presence of competition does neither increase efficiency nor does it yield any payoff gains for the short side of the market. We also find that...

Allowing for three labor market settings (perfect competition or right-to-manage bargaining, efficient bargaining and monopsony), this paper relies on an extension of Hall's econometric framework for estimating simultaneously price-cost margins and scale economies. Using an unbalanced panel of...

We extend Lazear’s theory of skills variety and entrepreneurship in three directions. First, we provide a theoretical framework linking new business creation with an entrepreneur’s skill variety. Second, in this model we allow for both generalists and specialists to possess skill variety....
