The problems of developing country dependence on a narrow range of commodity exports are well-established. Many poorer developing countries have continued to generate a substantial proportion of their total export revenues from one or a small number of basic food commodities. In addition to the problem of declining world market prices for basic food products typically exported from developing c...

The multi-transshipment problem is NP-hard already for two commodities over bipartite networks. Nonetheless, using our recent theory of n-fold integer programming and extensions developed herein, we are able to establish the polynomial time solvability of the problem in two broad situations. First, for any fixed number of commodities and number of suppliers, we solve the problem over bipartite ...

This paper extends the previous literature on optimal redistributive taxation in the presence of externalities to a multi-externality setting. While taxes on income and on 'clean' commodities are still una ected by the externalities, which con rms previous results, I nd that the existence of more than one externality-generating commodity has important implications for the optimal Pigouvian tax ...

Endogenous growth theory has had some success in explaining the observed data related to the process of economic growth. However, the results of the models in this literature are typically very sensitive to their micro-economic structure. It is therefore important to understand how the growth process behaves under more general specifications of such features as the number of commodities, the nu...

A wire, plaster, and wood sculpture of a DNA double helix with one mismatched base pair considers how we might justly weigh overall health equity against extremely costly interventions for uncommon genetic illnesses.
