Trevor Swan independently developed the neoclassical growth model. Swan (1956) was published ten months later than Solow (1956), but included a more complete analysis of technical progress, which Solow treated separately in Solow (1957). Reference is sometimes made to the quot;Solow-Swan growth...

This paper develops the idea that when markets are imperfectly competitive, final producers may gain from a joint venture that produces part of their input requirements even though marginal cost exceeds the input's market price. Production by the joint venture lowers the market price of the...

This paper develops a spacial model of ATM networks to explore the implications for banks and non-banks of interchange fees, foreign fees and surcharges applied to transactions by customers at other than an own-bank ATM. Surcharging raises the price (foreign fee plus surcharge) paid by customers...

This paper investigates the effect of endogenous horizontal product differentiation on trade patterns and the gains from trade under Bertrand and Cournot oligopoly. Firms differentiate their products to mitigate competition, but only if the investment required is not too high. Investment in...

This paper provides a new and simple model of endogenous horizontal product differentiation based on a standard demand structure derived from quadratic utility. One objective of the paper is to explain the “empirical Bertrand paradox” – the failure to observe homogeneous product Bertrand...

Large firms played a central role in the “new trade” models that became a major focus of trade economists in the early 1980s. Subsequent literature for the most part kept imperfect competition but jettisoned oligopoly. Instead, as the heterogeneous firms literature burgeoned in the 2000s,...

Despite valid criticisms, many developing countries have issued non-transferable import licenses to a limited number of final-good producers so as to restrict imports of an input capital equipment. This paper demonstrates that for a given import quota, such licensing restrictions can actually...

We examine conditions under which a low cost vertically integrated manufacturer has an incentive to export an intermediate product to its higher cost (vertically integrated) rival rather than to vertically foreclose, fully cutting off supplies. The nature of supply conditions in the importing...

This paper develops a model in which upstream network insiders' conduct relationship specific investment that induces the downstream firm to transact within networks. The scale of destination-country production and part-specific measures of the importance of network relationships and engineering...
