Though a lot of work has been done on the distribution of job tenures, we are still uncertain about its main determinants.In this paper, we stress random shocks to match productivity after the start of an employment relation.The specificity of investment makes hiring and separation decisions...

This paper determines the structural shocks that shape a firm's first year by estimating a structural model of firm growth, learning, and survival using monthly sales histories from 305 Texas bars. We find that heterogeneity in firms' pre-entry scale decisions accounts for about 40% of their...

Refinancing a mortgage is often one of the biggest and most important financial decisions that people make. Borrowers need to choose the interest rate differential at which to refinance and, when that differential is reached, they need to take the steps to refinance before rates change again....

A well-known principle of welfare economics states that an efficient resources allocation can be achieved in a competitive economy when market prices are in line with social marginal costs. When applied to the transport sector, this implies that the price of the various transport modes should be...

The paper studies the effect of scale economies on the optimal capacity adjustment of a mutiplant firm. It is shown that with increasing economies of scale plants are ranked in decreasing order, after which the optimal choice is to scrap the largest one. On the contrary, if there are decreasing...

The standard framework in which economists evaluate environmental policies is cost-benefit analysis, so policy debates usually focus on the expected flows of costs and benefits, or on the choice of discount rate. But this can be misleading when there is uncertainty over future outcomes, when...

Tools for recreational resources management are topics of great theoretical and practical interest. The most commonly used tool undoubtedly is the licence or permit. The implementation of a system of licences to regulate the use of a natural resource is far from simple as it presupposes the...

We develop an econometric model for firm exit, using stochastic dynamic programming (SDP) as a starting point. According to SDP, the value of an operating firm can be written as the sum of (i) the net present value of continuing production if the firm is committed to a future exit date, and (ii)...

Investment in pollution prevention technologies are often made under significant uncertainty about the future pay-off from the investments. However, as time passes some of the uncertainties may be resolved by new information, implying that the timing of investments becomes an important issue for...

The relationship between the concept of option value in the literature on environmental preservation and the financial theory of option value is discussed by Fisher (2000), suggesting an equivalence between the two concepts. In a recent paper, Mensink and Requate (2004) argue that Fisher's claim...
