This paper considers the relationship between external aid and development in Mozambique from 1980 to 2004. The main objective is to identify the specific mechanisms through which aid has influenced the developmental trajectory of the country and whether one can plausibly link outcomes to aid...

Cost-benefit and health policy studies often model a consequence occurring over time as a continuous stream of events. Such a consequence is measured by the rates at which events occur or by the states that occur, and the value of the consequence is measured by an integral. This paper presents a...

We consider the class of (finite) spatial games. We show that the problem of determining whether there exists a Nash equilibrium in which each player has a payoff of at least k is NP-complete as a function of the number of players. When each player has two strategies and the base game is an...

We survey methods for using micro data in the calibration of dynamic general equilibrium models.

This paper contributes to the micro-foundation of money in centralized markets with idiosyncratic uncertainty. It shows existence of stationary monetary equilibria and ensures that there is an optimum quantity of money. The rational solution of our model is compared with actual behavior in a...

Several models of intra-household decision making have been suggested in the literature. We present a framework that includes all suggested models and variants as special cases. We derive the theoretical predictions of these models for the relationship between expenditures on goods and the...

In the present paper a generalization of the Kalai-Smorodinsky solution to nonconvex n-person bargaining problems is provided. The generalization is obtained by a slight weakening of the axioms used in Kalai-Smorodinsky (1975) and Roth (1980).

Time-budget studies done among contemporary primitive people suggest that the first farmers worked harder to attain subsistence than their foraging predecessors. This makes the adoption of agriculture in the Stone Age one of the major curiosities in human cultural history. Theories offered by...

The paper considers various cooperative equilibrium/solution concepts for atomless exchange economies. A famous result states that in such economies the core is equal to the set of Walrasian equilibria. We consider two arguments against using the core as solution concept in large economies: (1)...

This paper traces the evolution of the international market for wheat from an emerging market structure after the repeal of the Corn Laws to a mature market characterized by efficient arbitrage after the introduction of the transatlantic telegraph and the growth of trade. Efficiency is...
