Theoretical models of group lending assume that all group members are identical in terms of their effect on repayment performance. In practice, however, this may not be true. We use a unique data set obtained from a survey of 160 borrowing groups in Jordan to investigate the impact of joint...

Several current issues in economics are centered on scheduling and matching problems, notably including the 2012 Nobel Prize winning work. Such problems usually lie outside the scope of most undergraduate courses. We present a relatively simple problem that can be used to introduce the graph...

This paper evaluates the impact of an area-based congestion pricing scheme in terms of its effectiveness on mitigating traffic congestion by using a system dynamics model. Unknown parameter values are calibrated using data available from the area-based pricing scheme implemented in the London...

In this survey, we present recent developments in the literature on Network games. We briefly cover the literature on Communication situations and the corresponding allocation rules. This is followed by a review on the existing player- and link-based fixed and flexible allocation rules for...

We consider a standard linear city model with two firms, where firms and consumers both incur transport costs. This is done by assuming that the total transport cost is shared by the buyers and sellers according to an exogenously given rule. In the model, firms choose locations and prices, with...

This paper combines the imperfect reliability model of Bala and Goyal [2000b] with the heterogeneous player model of Galeotti et al. [2006]. We compare existence, characterization and efficiency results in the resulting framework with the results in other frameworks allowing for imperfect...

This case study compares the Auto Restricted Zone Policy (ARZ) with price changes for parking permits in Louisiana State University (LSU). We find that ARZ has a more significant effect on the reduction in purchase of parking permits than price increases, albeit with a lag. We also find that...

The joint liability literature claims that positive assortative matching, or risk homogeneity, is always the first best solution. We examine this claim in presence of group formation costs and find that the assertion is not always true.

In this note we provide conditions which ensure the existence of Nash networks in One-way flow models with cost heterogeneity.
