Strategic interaction between public and private actors is increasingly recognised as an important determinant of agricultural market performance in Africa and elsewhere. Trust and consultation tends to positively affect private activity while uncertainty of government behaviour impedes it. This...

This experimental study investigates the behaviour of banks in a large value payment system. More specifically, we look at 1) the reactions of banks to disruptions in the payment system, 2) the way in which the history of disruptions affects the behaviour of banks (path dependency) and 3) the...

Donors often rely on local intermediaries to deliver benefits to target beneficiaries. Each selected recipient observes if the intermediary under-delivers to them, so they serve as natural monitors. These recipients may, however, withhold complaints to 'thank' the intermediary for selecting...

This paper examines the effectiveness of using asymmetric liability to combat harassment bribes. Asymmetric liability is a mechanism where bribe-takers are culpable but bribe-givers have legal immunity. Results from our experiment indicate that while this policy has the potential to...

This paper investigates the effectiveness of offering rewards for self reports as a means of combating collusive bribery. Rewarding self reporting theoretically sows distrust between parties tempted to exchange bribes and may reduce bribery even where authorities are otherwise ineffective in...

We study how conflict in a contest game is influenced by rival parties being groups and by group members being able to punish each other. Our main motivation stems from the analysis of socio-political conflict. The relevant theoretical prediction in our setting is that conflict expenditures are...

Donors often rely on local intermediaries to deliver benefits to target beneficiaries. Each selected recipient observes if the intermediary under-delivers to them, so they serve as natural monitors. However, they may withhold complaints when feeling unentitled or grateful to the intermediary for...

Bertrand competition under decreasing returns involves a wide interval of pure strategy equilibrium prices. We first present results of experiments in which two, three and four identical firms repeatedly interact in this environment. Less collusion with more firms leads to lower average prices....
