In this paper we develop a model to describe a firm’s demand for two production factors which is subject to the presence of nonconvex adjustment costs. In our model simultaneous adjustment of these two production factors may either increase or decrease the total costs incurred by the firm. The...

This paper develops a theoretical model of a worker's decision problem under uncertainty about the optimal separation time, when holding a representative outside offer but facing fixed costs of quitting. Implications of the model's closed form solution are consistent with the quit behavior of...

Optimal layoff rules in closed form are derived for all workers in a firm that downsizes under uncertainty and faces heterogeneous firing costs. The theoretical model predicts that the firm displaces workers with low firing costs, low expected future productivity growth, and low layoff option...
