Managers wish to motivate workers to exert effort. There is large literature on the use of wages and monetary incentives for this purpose, but in practice the “honor” or “prestige” of an award can be a significant motivator as well, unless the award is given so often that its prestige is...

We extend a well known differential oligopoly game to encompass the possibility for production to generate a negative environmental externality, regulated through Pigouvian taxation and price caps. We show that, if the price cap is set so as to fix the tolerable maximum amount of emissions, the...

We emphasize the importance to consider components of population growth — fertility and mortality - separately, when modeling the mutual interaction between population and economic growth. Our model implies that two countries with the same population growth will not converge towards the same...

There has been a recent upsurge of interest in probabilistic population projections. Two methods have been suggested in the literature for forecasting the inputs into those projections: (1) a random lines (RL) approach, and (2) a simple autoregressive approach (AR(1)). The purpose of this paper...

This paper discusses one of the most difficult issues in modeling complex population-environment interactions: The advantages and disadvantages of highly disaggregated empirical models versus highly reduced theoretical models. The analysis is carried out on the basis of the PEDA model, recently...

In this paper we present a budget-constrained optimal control model aimed at finding the optimal enforcement profile for a street-level, illicit drug crackdown operation. The objective is defined as minimizing the number of dealers dealing at the end of the crackdown operation, using this as a...
