Granger Causality of Interest Rate and Exchange Rate on Stock Volatility at Chicago Options Market

This paper investigates the Granger Causality test to determine the correlation between interest rates and exchange rates with the composite stock volatility measurement of different companies under the Chicago Board Options and Exchange. Using the daily sector data for all observed variables from the St. Louis Fed over the period of 2007-2012, as well as introducing the technique of autoregressive lag model, I have examined whether the current and the previous values of a particular volatility index, interest rate, and exchange rate could have significant Granger Causality effects to the return behavior of those other indices, interest rates, andexchange rates. A two-way Granger Causality test was performed within the R studio, and the estimated result makes it essential to understand how the stock volatility indices behave over the contemplated time, especially with the following changes in interest rate and exchange rate, thus forecasting one another. The result further indicates, in most cases, interest rates positively Granger cause the stock market volatility indices more than in comparison with the exchange rates within the time period, although both of them are identified as major determinants of stockprice volatility

Competitiveness of the knitwear industry in Bangladesh : a study of industrial development amid global competition

This paper assesses the technical efficiency and profitability of the knitwear industry in Bangladesh taking into account the sector’s role in poverty reduction. While stochastic frontier analysis was invoked to assess technical efficiency, three alternative measures, namely the rate of return, total factor productivity and the Solow residual, were used to gauge the extent and determinants of the profitability of the industry based on firm-level data collected in 2001. The estimation results indicate the high profitability of the knitwear firms. In Bangladesh, the dynamic development of the industry has entailed great diversity in efficiency in comparison with the garment industries of other developing countries. While there is a significant scale effect in profitability and productivity, no supporting evidence was found for the positive impact on competitiveness of industrial upgrading in terms of usage of expensive machinery and vertical integration and industrial agglomeration

Non-linear charge reduction effect in strongly-coupled plasmas

The charge reduction effect, produced by the nonlinear Debye screening of high-Z charges occuring in strongly-coupled plasmas, is investigated. An analytic asymptotic expression is obtained for the charge reduction factor which determines the Debye-Hueckel potential generated by a charged test particle. Its relevant parametric dependencies are analyzed and shown to predict a strong charge reduction effect in strongly-coupled plasmas.Comment: 4 figure

Maintaining Mutual Consistency for Cached Web Objects

Existing web proxy caches employ cache consistency mechanisms to ensure that locally cached data is consistent with that at the server. In this paper, we argue that techniques for maintaining consistency of individual objects are not sufficient—a proxy should employ additional mechanisms to ensure that related web objects are mutually consistent with one another. We formally define the notion of mutual consistency and the semantics provided by a mutual consistency mechanism to end-users. We then present techniques for maintaining mutual consistency in the temporal and value domains. A novel aspect of our techniques is that they can adapt to the variations in the rate of change of the source data, resulting in judicious use of proxy and network resources. We evaluate our approaches using real-world web traces and show that (i) careful tuning can result in substantial savings in the network overhead incurred without any substantial loss in fidelity of the consistency guarantees, and (ii) the incremental cost of providing mutual consistency guarantees over mechanisms to provide individual consistency guarantees is small
