We show that optimal public transport subsidy is sensitive to the use of alternative user cost models, and that a model based on cost minimisation principles may lead to an improvement in subsidy estimates. For the case of homogeneous consumers and non-peaked demand, the cost minimisation user...

The aim of this paper is to study the effects of credit constraints on the equilibrium aggregate capital stock. Credit constraints are the consequence of asymmetric information and moral hazard on the credit markets. When the equilibrium interest rate is low, entrepreneurs may have the...

Equilibrium search models require unobserved heterogeneity in productivityto fit observed wage distribution data, but provide no guidance about the location parameter of the heterogeneity. In this paper we show that the location of the productivity heterogeneity implies a mode in a kernel...

We study environments where a production process is jointly shared by a finite group of agents. The social decision involves the determination of input contribution and output distribution. We define a competitive solution when there is decreasing returns-to-scale and show that it leads to a...
