Commodity High Performance Computing at Commodity Prices
The entry price of supercomputing has traditionally been very high. As processing elements, operating systems, and switch technology become cheap commodity parts, building a powerful supercomputer at a fraction of the price of a proprietary system becomes realistic. We have recently purchased, in support of both our local and national collaborations, a dedicated computational cluster of eight D...
متن کاملCommodity Prices and Growth∗
In this paper we propose an endogenous growth model of commodity-rich economies in which: (i) long-run (steady-state) growth is endogenous and yet independent of commodity prices; (ii) commodity prices affect short-run growth through transitional dynamics; and (iii) the status of net commodity importer/exporter is endogenous. We argue that these predictions are consistent with historical eviden...
متن کاملDeterminants of Commodity Prices
Financial returns, although seemingly unpredictable, have been successfully modelled using market and macro-economic factors. The effect of these factors, however, may vary with time and only be statistically significant for specific periods. This paper utilises factors that have been found to capture financial market returns and applies them to the modelling of a broad set of commodities. A ch...
متن کاملCommodity Prices Revisited
Empiricaf models of commodity prices are potentially important aids to decision-makers, especially as the economy has grown more complex. A typicrd time series of commodity prices exhibks positive autocorrelation, occasional spikes, and random variability, and conceptual models have been developed to explain this behavior. But, the leap from theory to empirical applications is large because of ...
متن کاملBiofuel and Food-Commodity Prices
The paper summarizes key findings of alternative lines of research on the relationship between food and fuel markets, and identifies gaps between two bodies of literature: one that investigates the relationship between food and fuel prices, and another that investigates the impact of the introduction of biofuels on commodity-food prices. The former body of literature suggests that biofuel price...
