We simulate a spatial behavioral model of the diffusion of an infection to understand the role of geographical characteristics: the number and distribution of outbreaks, population size, density, and agents' movements. We show that several invariance properties of the SIR model with respect to...

In this paper we model a decision maker who must exert costly effort to complete a single task by a fixed deadline. Effort costs evolve stochastically in continuous time. The decision maker will then optimally wait to exert effort until costs are less than a given threshold, the solution to...

Many developing countries have suffered under the personal rule of “kleptocrats”, who implement highly inefficient economic policies, expropriate the wealth of their citizens, and use the proceeds for their own glorification or consumption. We argue that the success of kleptocrats rests, in...

This paper proposes an explanation of the puzzling coexistence of elements of both inertia and dynamism in the Russian labor market. In an environment of high uncertainty, risk averse and heterogeneous workers face a trade-off between wages and insurance against risk. The firm proposes a...

Many observers have noted a strong tendency for protection, once it is instituted, to persist over time. This paper first shows that persistent protection arises whenever lobbying is an alternative to costly adjustment. With endogenous protection, the level of tariffs is an increasing function...

Despite the fact that nonprofit organizations play a large role in the production and distribution of goods and services in modern economies, and the rising role of non-governmental organizations in carrying out projects in developing countries, our knowledge of their governance, and of its’...

Recent theoretical work has examined the spatial distribution of unemployment using the efficiency wage model as the mechanism by which unemployment arises in the urban economy. This paper extends the standard efficiency wage model in order to allow for behavioral substitution between leisure...

The aim of this paper is to explore the structure of cities as a function of labor differentiation, gains to trade, a fixed cost for constructing the transportation network, a variable cost of commodity transport, and the commuting costs of consumers. Firms use different types of labor to...
