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

Estimates of the number of people living in extreme poverty, as reported by the World Bank, figure prominently in international development dialogue and policy. An assumption underpinning these poverty counts is that there are no economies of scale in household size – a family of six needs...

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...

The fraction of R&D active firms decreased in Switzerland but increased in the Netherlands from 2000-2016. This paper examines reasons for this divergence and its impact on productivity growth. Our micro-data reveal R&D concentration among high-productivity firms in Switzerland. Innovation...

We document that for a group of high-income countries (i) mean earnings of managers tend to grow faster than for non managers over the life cycle; (ii) the earnings growth of managers relative to non managers over the life cycle is positively correlated with output per worker. We interpret this...

We estimate a measure of well-being efficiency that assesses countries' ability to transform inputs into subjective well-being (Cantril ladder). We use the six inputs (real GDP per capita, healthy life expectancy, social support, freedom of choice, absence of corruption, and generosity)...

This study is a review of the recent trends in development economics research. The focus is on the development in the recent decades as a result of increased globalization of knowledge, technologies and economies. In particular I look at the development in a number area where similar trends are...

We model the aid allocation decision where the donor government has announced that good governance is the criterion for receiving aid. Potential recipients must compete for the aid funds. The structure of the competition is important to the donor in terms of achieving good governance, and to the...
