P∈Pi P∋e fi,P ≤ ce ∀e fi,P ≥ 0 Dual 1 solves the max-sum multi-commodity flow problem: ce represents the capacity of an edge, and fi,P is the amount of flow directed from si to ti along the path P . The LP tries to maximize the total amount of commodity flow. Lemma 17.1.1 Multicut is always larger than the corresponding max-sum multi-commodity flow. Lemma 17.1.2 Multicut is at most O(logK) time...

We theoretically study how commodity financialization affects trading behavior, prices and welfare through affecting risk sharing and price discovery in futures markets. In our model, the general equilibrium feature makes financial traders either provide or demand liquidity in the futures market, depending on the information environment. Consistent with recent evidence, commodity financializati...

This paper presents a method for computing shadows on incomplete point-based isosurfaces. Such surfaces are obtained in our setting by a view-dependent isosurface extraction method that allows interactive exploration of large scale datasets on commodity hardware. This approach raises the need for a novel and efficient technique to generate high-quality shadows. The latter dramatically enhances ...

The Internet is rapidly growing in number of users, traffic volume, and topological complexity. At the same time it is increasingly driven by economic competition. These developments render it more difficult, and yet more critical, to characterize network usage and workload trends, and point to the need for a high performance monitoring system that can provide workload data to Internet users an...

The authors found that, concurrent with the rapidly growing index investment in commodity markets since the early 2000s, prices of non-energy commodity futures in the United States have become increasingly correlated with oil prices; this trend has been significantly more pronounced for commodities in two popular commodity indices. This finding reflects the financialization of the commodity mar...

This paper presents a theory of inflation in an economy with commodity money and supports it by evidence from the inflationary episodes in France during the fourteenth and fifteenth centuries. The paper shows that commodity money can be inflated similarly to fiat money through repeated debasements, which act like devaluation. Furthermore, as with fiat money, demand for commodity money falls wit...

The construction of commodity-by-commodity input-output matrices from Make and Use matrices is a much debated area. Different views compete with each other, both in theoretical aspects as in practical appraisement of the importance of the various issues involved. The commodity-technology assumption and the industry-technology assumptions form the basic theoretical concepts between which one mus...
