In this paper we investigate the incentives of unemployed workers to wait for a recall when recall probabilities are endogenously determined by the waiting decisions of others. Because of a positive externality that arise when workers seek new employment, an excessive number of workers choose to...

There is concern that prices in a market for Green Certificates (GCs) primarily based on volatile wind power will fluctuate excessively, leading to corresponding volatility of electricity prices. Applying a rational expectations simulation model of competitive storage and speculation of GCs the...

In this paper we analyse early retirement for men and women focusing on family characteristics such as marital status, spouse income and wealth, and spouses’ labour market status. The female participation rate is high in Norway, implying that the country is particularly suitable for the study...

We consider the effects of international environmental agreements, using the Sofia Protocol on the reduction of nitrogen oxides. Our analysis utilizes panel data from 25 European countries for the period 1980–96. We divide these countries into “participants” and...

We analyse how the internal organisation of firms affects the correspondence between private and social incentives for horizontal merger. Applying a model of endogenous merger formation in a three-firm asymmetric Cournot industry, we contrast the cases of entrepreneurial and managerial firms....

We analyze the dynamic interaction between imitation and myopic optimization in an environment of changing marginal payoffs. Focusing on finite irreducible environments, we unfold a trade-off between the degree of interaction and the size of environmental shocks. The optimizer outperforms the...

In a non-cooperative oligopoly model where firms use simple linear prices, Klemperer (1987) has shown that the existence of consumers’ switching costs may generate monopoly like prices, and thereby create substantial loss in welfare. We show that when allowing firms to use two-part tariffs,...

Physicians are key personnel in a sector which is important due to its size as well as the quality of service it provides. We estimate the labor supply of physicians employed at hospitals in Norway, using personnel register data merged with other public records. A dynamic labor supply equation...

In this paper we analyze the pattern of employment adjustment using a rich panel of Norwegian plants. The data suggest that the frequency of episodes of zero net employment changes is inversely related to plant size. We develop and estimate a simple “q” model of labor demand, allowing for...

We analyse how equilibrium locations in location-price games à la Hotelling are affected when firms acquire inputs through bilateral monopoly relations with suppliers. Assuming a duopoly downstream market, we consider the case of two independent input suppliers bargaining with both downstream...
