Estimates of price substitution among capital, labor, and energy are critical to numerous policy issues. Estimating factor share equations of the translog production function requires constant returns to scale and competitive factor markets. The present estimates find mixed evidence on these...

The wage impact of immigration depends crucially on the elasticity of substitution between similarly skilled immigrants and natives and the elasticity of substitution between high school dropouts and graduates. This paper revisits the estimation of these elasticities. The U.S. data indicate that...
