We examine a stark setting in which security or protection can be provided by self-governing groups or by for-profit entrepreneurs (kings, kleptocrats, or mafia dons). Though selfgovernance is best for the population, it faces problems of long-term viability. Typically, in providing security the...

Incentive effects of depreciation rules for risk-taking are considered. If true economic depreciation is stochastic, profit taxes with expected-value depreciation allowances decrease risk-taking. However, if real capital is used only in the risky sector, more generous depreciation allowances...

The standard contest model in which participants compete in a single dimension is well understood and documented. Multi-dimension extensions are possible but are liable to increase the complexity of the contest structure, mitigating one of its main advantages: simplicity. In this paper we...

Where product innovation requires several complementary patents, fragmented property rights can be a factor that limits firms’ willingness to invest in the development and commercialization of new products. This paper studies multiple simultaneous R&D contests for complementary patents...

We characterize the unique Markov perfect equilibrium of a tug-of-war without exogenous noise, in which players have the opportunity to engage in a sequence of battles in an attempt to win the war. Each battle is an all-pay auction in which the player expending the greater resources wins. In...

We study equilibrium in a multistage race in which players compete in a sequence of simultaneous move component contests. Players may win a prize for winning each component contest, as well as a prize for winning the overall race. Each component contest is an all-pay auction with complete...

We study the residential choice of siblings who are altruistic towards their parents. The firstborn child's location choice influences the behavior of the second-born child and can shift some of the burden of providing care for the parents from one child to the other. These strategic...

This Paper compares education investment in closed and open economies without government and with a benevolent government. Closed economies suffer from a hold-up problem of excessive redistribution, and governments use education policy as a second-best tool. Globalization that increases labour...

We study the residential choice of siblings who are altruistic towards their parents. If some sibling moves further away, he or she can shift some of the burden of taking care of the parents to his or her siblings. Thus, siblings have a strategic incentive to move away that only children do not...
