Markov perfection has become the usual solution concept to determine the non-cooperative equilibrium in a dynamic game. However, Markov perfection is a stronger solution concept than subgame perfection: Markov perfection rules out any cooperation in a repeated prisoners' dilemma game because the...

Intergenerational altruism and contemporaneous cooperation are both important to the provision of long-lived public goods. Equilibrium climate protection may depend more sensitively on either of these considerations, depending on the type of policy rule one examines. This conclusion is based on...

Cobb Douglas production function parameters are not identified from cross-section variation when inputs are perfectly flexible and chosen optimally, and input prices are common to all firms. We consider the role of adjustment costs for inputs in identifying these parameters in this context. The...

This study examines the impact of inflows of foreign workers on Korean natives' economic performance - namely, employment - through the Employment Permit System, the basis of Korea's system by which to introduce low-skilled immigrants. Using National Employment Insurance data, analyses reveal...

This paper investigates under which conditions firms use fixed-term contracts, subcontracted and freelance work. Using a probit model which accounts for unobserved heterogeneity, we find that positive changes in expected or actual turnover are associated with a higher probability of employing...

Adjustment costs cause movements of the labour share if the economy experiences demand or wage shocks. With linear adjustment costs and Cobb-Douglas technology, these movements are independent of the size of these shocks and depend only on the size of the adjustment costs.

Transition from one economic equilibrium to another as a consequence of shocks is often associated with sunk adjustment costs. Firm specific sunk market entry investments (or sunk market exit costs) in case of a reaction to price shocks are an example. These adjustment costs lead to a dynamic...

The macroeconomic implications of firms' lumpy investment behavior are subject to ongoing research. Lumpy investment results from fixed capital adjustment costs which give firms an incentive to reduce the frequency of capital adjustments. However, previous studies have underestimated the...

This paper introduces aging of workers into the neoclassical theory of labor demand. Among other things, it is shown that under reasonable hypotheses employment, even of younger workers, increases in the span of working life. Using the standard model without aging, the analysis of such issues...

This paper discusses the measurement of production and employment effects of trade policy, and more broadly the effects of economic integration and globalization. First, it provides a broad-brush overview of the ex-post literature linking trade to performance, such as measures of worker...
