This paper introduces farm-heterogeneity in measuring technical efficiency of Swedish dairy farms using farm-level data. In calculating technical efficiency which is allowed to vary over time and across farms, we control for farm-specific effects. This is possible only when panel data is available. Furthermore, we separate technical efficiency from technical change—the presence of which is indicated by a shift in the production function over time,ceteris paribus. We also calculate percentage change in technical efficiency to examine whether farm efficiencies have improved over time. Finally, a comparison of technical efficiency, elasticities of different inputs, and technical change is made across different years and panels. The data includes four panels of dairy farms observed during the period 1976–1988, excluding 1985.We thank two anonymous referees, Anders Klevmarken and Lennart Hjalmarsson for valuable comments.

The effects of match uncertainty and bargaining on labor market outcomes: evidence from firm and worker specific estimates 总被引:3,自引:0,他引:3
In this paper we examine wage dispersion in labor markets across currently employed workers. We argue that differences in
the potential productivity of a match (typically assumed to be known in the previous literature) generates a surplus between
the minimum wage the worker is willing to accept and the maximum wage the firm is willing to offer for the job. Existence
of this surplus leads to wage dispersion due to negotiating over the amounts extracted by each agent. Our objective is to
estimate the surplus extracted by each firm-worker pair and the effect of the net extracted surplus on the wage, for each
firm-worker pair using the two-tier stochastic frontier model. An empirical application finds that, on average, firms paid
workers less than their expected productivity. More specifically, at the mean, the net effect of productivity uncertainty
leads to equilibrium wages which are 3.33% below the expected productivity of matches.
