Using a sample of commodity spot price indexes over the period 1947-2010, we examine predictability of commodity returns at the monthly, quarterly, and annual horizons. We establish out-of-sample predictability by means of variables such as bond spreads, growth in money supply and industrial production. Predictability is strongest for raw industrials and metals indexes and weakest for foods and...

Maximization of flow through the network has remained core issue in the field of optimization. In this paper a new advanced network problem is introduced, i.e., a multi-commodity network with a separator. This network consists of several sub-networks linked through a commodity separator. The objective is to maximize the flow of the commodity of interest from the commodity mixture at the output ...

A computational model of a simple commodity economy is examined and a theory of the relationship between commodity values, market prices and the efficient division of social labour is developed. The main conclusions are: (i) the labour value of a commodity is an attractor for its market price; (ii) market prices are error signals that function to allocate the available social labour between sec...

Packet generation is crucial to network measurements. Despite its importance, software packet generators lack the accuracy and precision to model realistic test scenarios [1]. Hardware traffic generators provide the necessary precision and accuracy but tend to be inflexible and expensive. MoonGen presents a novel approach to provide flexible, accurate, and precise traffic generation in software...

Servitization is a process of creating value by shifting from merely selling products to selling solutions that integrate products and services. It is a strategy often used by manufacturing SMEs to avoid or escape the commodity trap. Research has illustrated that servitization can lead to a competitive advantage in the marketplace, but many SMEs still fail to servitize successfully. In this pap...

government interventions in agricultural markets in order to stabilize commodity prices and producer incomes have had a long tradition. intervention has been at both the state and country levels and has been for the most part in the form of commodity-based schemes. this study represents an attempt to develop an appropriate methodology for analyzing the aggre-gate effects of a particular type of...
