We use modern household data and econometric methods to conduct some of the original tests of the Permanent Income Hypothesis (PIH) suggested and used by Friedman (1957). The data and methods are superior to those available to Friedman, allowing us to refine Friedman’s tests and perform tests...

In this paper we introduce resampling techniques to a multi-layer feed-forward neural network model for noisy financial time series in order to obtain more reliable interval forecasts of the time series along with a large amount of statistical information associated with the observed data. In...

This paper examines the effect of the proportion of females in the establishment on the male/female wage gap and the effectiveness of an affirmative action program in reducing this gap. A unique data set makes this paper possible since it has information on both individuals and the...

Recently Wang and Wirjanto (1997) proposed a simple dynamic model to study the optimal timing strategy for an individual's migration decision, using the theory of the optimal timing of investment under uncertainty, reviewed in Dixit (1992), Dixit and Pindyck (1994), and Pindyck (1991). It is...

There is substantial empirical literature which examines the relationship between private and public consumption. The conclusions from this literature, however, are generally mixed. In this paper, we attempt to provide some additional evidence on this relationship. We consider a two-good...

Building on recent advances in the theory of the optimal timing of investment under uncertainty, this paper proposes a stylized theoretical model to study an individual's optimal migration strategy. It shows that, as a result of following the optimal strategy, the individual may choose to delay...

Scientific research and private-sector technological innovation are different in terms of objectives, constraints, and organizational forms. For example, the for-profit objective that drives private-sector innovation is absent from much of scientific research, and individual researchers have...

The optimal management of a non-renewable resource extraction project is studied when input and output prices follow correlated stochastic processes. The decision problem is specified by two Bellman equations describing the project when it is currently operating or mothballed. Solutions are...

There exists a large literature on the optimal deterrence of crime. Within the literature, however, there exists a controversy over what the appropriate criterion to determine optimality should be. While the most popular method is that of maximization of a utilitarian welfare function, another...
