With several identical deposits of an exhaustible non-reproducible resource, the working of a deposit entails a set-up cost but no other cost. The deposits must be extracted in strict sequence with jump discontinuities of marginal benefits at transition points. Moreover, the average rate of...

We investigate an intertemporal model with an exhaustible resource inflowwhich exhibits a single peak in consumption on the path of development. Thepeak follows the date at which net investment is zero. The ``top'' ofconsumption is higher and flatter and peaks later when the discount rate...

We take up a growth model with both skilled and unskilled labor, and a steady migration of some unskilled workers, who undertake apprenticing, to the skilled group of workers. Apprenticing involves a period of observing and thus labor output foregone. The time-out for observing represents a cost...

We investigate economic depreciation of natural capital for cases of non-stationary output prices, technology and interest rates. For the former two cases (exogenous movements in prices and technology), constant consumption emerges under a strategy of investing to cover off economic...

We investigate the effect of stock discovery on the profits of non-identical oligopolists. We show that a uniform addition to all stocks could harm firms that are originally larger than average. One conclusion that could be drawn from the results is that a new technology that leads to more...

We show that, even with flexible domestic wages, international outsourcing may worsen the welfare of the home country and reduce the profits of all firms. If wages are rigid, outsourcing is welfare-improving if and only if the sum of the "trade creation" effect and the "exploitation effect"...

Ranking development programs using integrals of discounted utilities can yield drastic consequences that offend our sense of justice. New alternative social welfare criteria should be considered. A reaction to discounted utilitarianism is to moderate its effects by adding to the social welfare...
