On the shape of the single-country and world commodity-substitution and factor-substitution surfaces under conditions of joint production

In recent years trade theorists have completed the task of specifying necessary and sufficient conditions for the single-country and world transformation surfaces to be locally of any assigned degree of flatness. However those conditions are relevant only if the technology is of the no-joint-products type. In the present note we derive necessary and sufficient conditions for the single-country and world transformation surfaces to be of any assigned degree of flatness under conditions of joint production; and we also obtain, as a by-product, necessary and sufficient conditions for the single-country and world equal-product surfaces to be of any assigned degree of flatness.     

Factor-Market Distortions, Dynamic Stability, and Paradoxical Comparative Statics

In the late 1960s and early 1970s there was a strong revival of interest in the role of factor-market distortions in those branches of our subject which rely on the Lerner–Samuelson two-by-two model of production. Among the legacies from that period were several comparative statical propositions which seemed counterintuitive or paradoxical. However, the revival lost momentum when confronted with Neary's observation that the major paradoxes are associated with unstable equilibria and therefore rarely observed. On the other hand, there are now seen to be several errors in Neary's analysis. For example, in the important case of a closed economy (and, by interpretation, in the case of a large open economy) he overlooked the fact that paradoxes can be associated with stable equilibria.     

Optimal Two‐Part Pricing in a Carbon Offset Market: A Comparison of Organizational Types

This article examines the optimal two‐part pricing by an intermediary in a carbon offset market. In addition to creating a framework for analyzing carbon offset pricing, this article makes two contributions to the theoretical literature. First, we provide an in‐depth examination of the roles played by the upstream inframarginal supply and participation elasticities and the downstream demand elasticity in determining the optimal two‐part pricing strategy. Second, we compare the pricing decisions of three different organizational types: a for‐profit firm, a public agency, and a producer association. The producer association problem, which has received little attention in the literature, yields counterintuitive results because a producer association must simultaneously reduce output and distribute all profits back to its members.     

The Internationalization of the World Economy and its Implication for National Welfare

There is no generally accepted definition of internationalization or globalization. The present paper offers three alternative definitions, in terms of (i) an enlargement of the set of trading countries, (ii) an enlargement of the set of traded commodities, or (iii) the international sharing of technology. It is shown that if each country adopts a Paretian scheme of internal compensation then internationalization in each sense leaves at least one country better off, and that if international compensation is admitted then internationalization in each sense makes every country better off.
