We study the impact of transparency in a commodity market on the decision problem of a competitive firm under price uncertainty and hedging opportunities. Market transparency is modeled by means of the informational content of publicly observable signals which are correlated with the random price. We find that the impact of more transparency on labor employment and production depends on the fir...

RNA-protein cross-linked complexes were isolated and purified to obtain precise data about RNA-protein contact sites in the 50 S ribosomal subunit of Escherichia coli. N-terminal microsequencing and matrix-assisted laser desorption ionization MS were used to identify the cross-linking sites at the amino acid and nucleotide levels. In this manner the following contact sites of five ribosomal pro...

In a large sample of entrepreneurs, 2D:4D (second-to-fourth digit) ratio and managerial performance are studied. Entrepreneurs with lower ratio manage larger firms, manage larger firms when acquire control and experience faster average growth. Firms run by high prenatal testosterone entrepreneurs have lower profitability as measured by return on assets and return on sales. Prenatal testosterone...

We analyze the incentives for a two-sided intermediary to divert consumers to its favored destinations. Using a quasi-experiment to control for search intent, we identify and measure the impact of a search engine’s exclusive award of preferential placement to its own service. We find that Google’s differential placement of its Flight Search service led to a 65% decrease in click-through rates f...

In this work, the structural, magnetic, thermal, and transport properties of arc-melted polycrystalline Heusler alloy Co2Ti1.5Sn0.5 are investigated. The crystallizes in an L21 structure with a space group Fm-3m. magnetic depict its antiferromagnetic nature exhibits ordering around Neel Temperature TN = 8.5 K. effective moment value obtained from Curie –Weiss law suggests that cobalt atom is lo...
