We analyze the technical efficiency of German and Swiss urban public transport companies by means of SFA. In transport networks we might face different network structures or complexities, not observed, but influencing the production process. The unobserved factors are typically modeled as...

In this paper we define and estimate measures of labor market imperfection in the context of an equilibrium search and matching framework. The method uses readily available data on distributions of unemployment and job durations and wages. We estimate an index of search frictions, the magnitude...
