Consider a dynamic duopoly model where R&D spending is used to increase the reliability of a firm's product under two competitive scenarios: the home firm competes with a "complacent" foreign firm that does no R&D whatsoever or with a "lockstep" foreign firm that improves its product at exactly...

Consider a dynamic intra-industry trade model with two goods, two firms, and two countries in which product ¡°reliability¡± is determined by R&D paths. This paper focuses on how a change in competitive conditions in terms of manufacturing costs affects the firms¡¯ decision about optimal...

The present paper examines the welfare effects of a dynamic Research and Development (R&D) game at the firm level in a two-country, two-firm, intra-industry trade context. Economists do not use the trade balance as a measure of economic welfare, but it is often used in the public arena. The...

The paper considers a dynamic model in which an income stream,growing over time, is optimally divided into consumption andexpenditures on waste disposal, the latter being optimally dividedbetween ``recycling''and ``landfilling.'' Recycling is thoughtof as a ``backstop'' waste disposal technology...

The Forward-Backward Sweep Method is a numerical technique for solving optimal control problems. The technique is one of the indirect methods in which the differential equations from the Maximum Principle are numerically solved. After the method is briefly reviewed, two convergence theorems are...

The paper consists of an investigation of Donald McCloskey’s proposition that economic journals contain both metaphors and allegory. The first section consists of a definition of allegory where it is shown that the defining trait of allegory is that it can be read on two levels, the...

This paper investigates government subsidy games for private sector research and development (R&D) in a two-country two-firm intra-industry trade model. Two funding structures are compared: “cost sharing” vs. “reward for performance.” Both the theoretical evidence and the results of a...
