Jones (1971) examines a three-factor two-good model under the assumption that two of the factors are specific to one sector (a different sector for each such factor). In this paper that specification is weakened, so that only one sector (agriculture) has a specific factor (land). When land is a...

A simple account of globalization would have it that international trade in today’s world is a club to which all are welcome.

A Toy Model is a simple economic model, with no claims to generality. These models are usually constructed for some specific purpose. That was the origin of the famous trade model, the Heckscher-Ohlin-Samuelson (HOS) Model, originally constructed to model Nineteenth Century transatlantic trade....

The paper examines some implications of the wholly reasonable assumption that the elasticity of intertemporal substitution (the EIS) increases with the level of consumption. Then the rich find it easier to substitute future consumption for present consumption than do the poor. In the empirical...

The single-agent smash and grab problem take the form Max_xU(x).h(x). The agent selects a target value (how much to grab). The probability that he will receive (get away with) x is h(x), the cumulative probability distribution of the maximum achievable level of x. Generalizations are developed...

A convergence model in which wealth accumulation is subject to i.i.d. random shocks is examined. The accumulation functions shows what k_{t+1} - wealth at t+1 - would be given k_t and with no shock. It has a positive slope, but its concavity or convexity is indeterminate. The focus is the...
