We use nonparametric production-frontier methods to decompose the growth of labor productivity of Chinese provinces in the post-reform period. These techniques, combined with kernel density estimates, allow us to decompose the shift in the distribution of labor productivity without the need for...

Is public expenditure productive? Is there a shortfall or excess in public capital investment? We address these old issues in light of new econometric tools. It is argued that the Cobb-Douglas specification that ignores nonlinearity inherent in the functional relationship of the production...

This paper uses nonparametric kernel methods to construct observation-specific elasticities of substitution for a balanced panel of 73 developed and developing countries to examine the capital-skill complementarity hypothesis. The exercise shows some support for capital-skill complementarity,...

When analyzing what determines the efficiency of production, regressing efficiency scores estimated by DEA on explanatory variables has much intuitive appeal. Simar and Wilson (2007) show that this nai͏̈ve two-stage estimation procedure suffers from severe flaws, that render its results, and...
