Let an organization, such as a government or a firm, evaluate projects with the aim of maximizing social welfare or profits. Each project is evaluated by an agent, who may err. Some agents, however, are more likely to make a correct evaluation. Agents may revealed as making correct evaluations...

We show that even under socially constant returns to scale indeterminacy, i.e., a continuum of dynamic general equilibrium paths converging to a common steady state, can arise in a dynamic Heckscher-Ohlin model with production externality and endogenous time preference in which production is...

This note provides a simple proof of the necessity of the transversality condition for the differentiable reduced-form model. The proof uses only an elementary perturbation argument without relying on dynamic programming. The proof makes it clear that, contrary to common belief, the necessity of...

This paper establishes (i) an extension of Michel's (1990, Theorem 1) necessity result to an abstract reduced-form model, (ii) a generalization of the results of Weitzman (1973) and Ekeland and Scheinkman (1986), and (iii) a new result that is useful particularly in the case of homogeneous...

We extend the basic equilibrium search model of Burdett-Mortnesen with a human capital accumulating wage function and solve for the new equilibrium distribution of wages. We find an equilibrium distribution of earned wages with no upper bound of the support and with density having a decreasing...

Numerous economic problems assume the form of finding a fixed point of a continuous self-mapping on a compact interval. We consider instances where the mapping is a parametrized expected value, and we offer an iterative scheme for locating a fixed point. The proposed method can be seen as an...

The purpose of this paper is to propose an innovative method of evaluating the performance of active fund managers, by introducing to the field of performance measurement the more appealing loss aversion utility theory. We combine the latter to an already established performance measure...

This paper simulates a gbuffer-stockh saving model of precautionary saving and estimates the parameters of the utility function by matching the simulated age-consumption profile with those observed in the micro-level data from the Family Income and Expenditure Survey (FIES) in Japan. Our...

This note studies a general nonstationary infinite-horizon optimization problem in discrete time. We allow the state space in each period to be an arbitrary set, and the return function in each period to be unbounded. We do not require discounting, and do not require the constraint...
