Some Challenges for Reformers and Architects

In these brief concluding remarks, I confine myself to a few reflections on some of the themes that have been broached today, without much reference to individual authors or comments, as it would be impossible to summarize everything that has been said at this conference about the new architecture of the international monetary system.

Industry restructuring and regulation: Building a base for sustainable growth - lessons from Latin America

The potential for economic growth of nations is related to the state of their infrastructure. In this connection, it has been estimated that one percent growth in GDP requires an investment of one percent of GDP in energy, transportation, telecommunications, and water and sanitation infrastructure.     

Heterogeneity, returns to scale, and collective action

Abstract .  I analyze the effects of resource inequality and valuation heterogeneity on the provision of public goods with increasing or decreasing returns to scale in production. The existing literature typically takes the agents' characteristics as given and known to the researcher. In contrast, this paper compares collective action provision across groups of agents with resources and valuations for the public good drawn from different known joint distributions. Specifically, I characterize the expected equilibrium public good level as function of various distributional properties and moments. A resource-valuation distribution that first-order stochastically dominates another distribution always results in higher expected public good provision level, independent of the production technology. With decreasing returns to scale in the public good production, higher resource inequality results in higher expected provision. With increasing returns the same result holds when the mean resource level is relatively low, but expected provision decreases in inequality when the mean resource level is high. A parallel result holds for agents' valuations.     

CONSTRUCTING IMPACT FACTORS TO MEASURE THE INFLUENCE OF SUPPLY CHAIN MANAGEMENT AND LOGISTICS JOURNALS

Data from ten supply chain management and logistics journals are combined with data from the ISI Web of Science database to develop a series of impact factors. The resulting constructed impact factors provide a context for comparing and ranking leading academic supply chain management and logistics journals. They also provide an objective way of comparing the relative influence of supply chain management and logistics journals, as well as a platform for comparing their influence with that of journals in more general fields like management and business.
