We model an infinitely repeated Tullock contest, over the sharing of some given resource, between two ethnic groups. The resource is allocated by a composite state institution according to relative ethnic control; hence the ethnic groups contest the extent of institutional ethnic bias. The...

We examine how cross-community cost or benefit spillovers, arising from the consumption of group-specific public goods, affects both inter-group conflicts over the appropriation of such goods and decentralized private provision for their production. Our model integrates production versus...

We model simultaneous inter and within identity-group conflict in two territories connected by cross-territorial spill-overs. Within each territory, two groups contest the division of a group-specific public good, and all members contest the division of group income. Each group has a...

We model political contestation over school language policy, within linguistic communities where weak property rights protection leads to high decentralized expropriation. We show that improvements in governance institutions that facilitate property rights protection might exacerbate such...

We model a contest between two groups of equal population size over the division of a group-specific public good. Each group is fragmented into sub-groups. Each sub-group allocates effort between production and contestation. There is perfect coordination within sub-groups, but sub-groups cannot...

Much of the existing literature on the use of informal credit arrangements such as ROSCAs (Rotating and Credit Saving Associations) theorises the use of such institutions as arising from market failures in the development of formal saving and credit mechanisms. As economic development proceeds,...

Non-positivity of the generalized substitution effect, non-positivity of the own-price substitution effect, homogeneity of degree zero in all prices and income, and the law of demand are some of the most primitive comparative static results in the standard revealed preference theory of...

Lenders condition future loans on some index of past performance. Typically, banks condition future loans on repayments of earlier obligations whilst international organizations (official lenders) condition future loans on the implementation of some policy action ('investment'). We build an...

We model a general choice environment via probabilistic choice correspondences, with (possibly) incomplete domain and infinite universal set of alternatives. We offer a consistency restriction regarding choice when the feasible set contracts. This condition, 'contraction consistency', subsumes...

In developing societies, social norms typically ascribe differential weights to paternal, maternal and communal (or state) contributions to children's expenses. Individuals internalize these valuations. I examine a Cournot model of voluntary contribution to children's goods in a two-adult...
