We generalize the normalized Constant Elasticity of Substitution (CES) production function by allowing the elasticity of substitution to vary isoelastically with (i) relative factor shares, (ii) marginal rates of substitution, (iii) capital-labor ratios, or (iv) capital-output ratios. Ensuing...

Several authors have proposed staggered wage bargaining as a way to introduce sticky wages into search and matching models while preserving individual rationality. I evaluate the quantitative implications of such an approach. I feed through a series of estimated shocks from US data into a search...

The literature on unemployment has mostly focused on labor market issues while the impact of capital formation is largely neglected. Job-creation is often thought to be a matter of encouraging more employment on a given capital stock. In contrast, this paper explicitly deals with the long-run...

We incorporate a variable elasticity of substitution production function into an overlapping generations model à la Diamond (1965). We show that a certain parameter in the production function is a source of biased technical change is a crucial determinant of the economy's growth dynamics. For...

We provide industry-level estimates of the elasticity of substitution (σ) between capital and labor in the US economy. We also estimate rates of factor-augmentation. Aggregate estimates are produced using the same data. Our empirical model comes from the first-order conditions associated with a...

I develop an extension of the neoclassical growth model in which firms are heterogeneous both in terms of labor share and productivity. In this model, distortions in the allocation of resources across firms can impact the labor share of national income. Using administrative firm-level data to...

The elasticity of substitution between capital and labor and, in turn, the direction of technical change are critical parameters in many fields of economics. Until recently, though, the application of production functions with non-unitary substitution elasticities (i.e., non Cobb Douglas) was...
