Motivated by increased agricultural commodity price volatility and surges during the past decade, we investigated whether financial speculation is to blame. The aim of this paper build on prior research about what extent in which ways undermines prices. In our analysis, utilized daily returns milling wheat, corn, soybean futures from Euronext Commodities Paris market (MATIF) as well short-term ...

Data dependences are one of the main limits to the amount of ILP that current processors can exploit. Data speculation are becoming a promising mechanism to avoid the ordering imposed by data dependences. This work presents two different approaches for improving the performance of current superscalar processors through data speculation. First, the impact of data speculation is studied for an id...

The article positions the author’s work as speculative design but—like the term design fictions—is open to several interpretations. How is the fictional character of such work conceptualised and produced? What kinds of speculation are involved? The article considers the value of one particular approach and argues that speculative design serves two distinct purposes: first, to enable us to think...

The Austrian theory mainly deals with analyzing the effects of an increased credit offer on productive structures. In this respect, we propose to link long-term growth cycles to various short-term interest rate gaps. Are European Business Cycles affected when a fall in the money market rate disrupts agents' expectations of inflation? Using the hypothesis that individual speculation is motivated...

Method level speculation (MLS) is an optimistic technique for parallelizing imperative programs, for which a variety of MLS systems and optimizations have been proposed. However, runtime performance strongly depends on the interaction between program structure and MLS system design choices, making it difficult to compare approaches or understand in a general way how programs behave under MLS. H...
