It is obvious that even though modern public choice theories, which were first developed for Western pluralistic societies (society-centred), might have highlighted many hidden subjects in developing countries such as rent-seeking, corruption, strong state tradition, undemocratic decision...

I present a dynamic evolutionary game model to address the relation between nationalism against immigrants and assimilation of the latter into the host country culture. I assume a country composed of two different large polymorphic populations, one of native citizens and the other of immigrants....

We study linear quadratic games played on a network where strategies are complements between neighbors and substitutes between agents at distance-two. We provide micro-founded problems where this pattern of interaction is due to a local congestion effect. Equilibrium behavior systematically...

Online auctions with a fixed end-time often experience a sharp increase in bidding towards the end despite using a proxy-bidding format. We provide a novel explanation of this phenomenon under private values. We study a correlated private values environment in which the seller bids in her own...

We compare economic and environmental outcomes under mixed and private oligopolies, in order to examine the effects of privatization when firms invest in abatement and emissions are taxed. We show that the number of competing firms in the market is an important factor in the determination of...

We present a theoretical model of moral hazard and adverse selection in an imperfectly competitive loans market that is suitable for application to Africa. The model allows for variation in both the level of contract enforcement (depending on the quality of governance) and the degree of market...

A critical element in all discounted utility models is the specification of a discount function. We introduce three functions: the delay, speedup and generating functions. Each can be uniquely elicited from behaviour. The delay function determines stationary and the common difference effect. The...

We present a modified citizen-candidate model where the implemented policy arises from a compromise between the government and an unelected external power. We show that the two-candidate equilibria of this model differ significantly from the original: however small the cost of candidacy, the...

This paper provides a theoretical model for explaining the separation of ownership and control in fi rms. An entrepreneur hires a worker for providing effort to complete a project. The worker's effort determines the probability that the project is completed on time, but the worker receives...
