Farmers' attitude towards risk associated with the availability of energy inputs will influence their investment behavior and demand for energy inputs. In order to analyze policies that reduce the risk in energy availability, some modifications in methods are required. This study, using a mean-variance framework, demonstrates how cross-sectional data and time-series data on crop yields and prices can be used to analyze agricultural energy policies under uncertainty in a developing country context. It is argued that the farmers risk attitudes, their crop allocation behavior, changes in the demand for energy inputs and the stochastic relationship between various forms of energy inputs can be explained by the various energy constraints faced by them. Furthermore, using the same methods the impact of policies which affect these constraints, can be analyzed.  相似文献

This study examines whether a stronger corporate governance enforcement regime influences the investment decisions of foreign portfolio investors in an emerging market context. Using a natural experiment provided by an Indian corporate governance regulatory reform introduced in 2000, but for which stricter sanctions for non-compliance were imposed in 2004 our results provide strong evidence that governance reforms that include stricter sanctions for non-compliance lead to higher foreign ownership. Depending on specifications, the difference-in-differences estimates show that, on average, the effect is up to 2.8% increased foreign ownership post regulatory reform of 2004. The paper adds to the debate on simultaneity between foreign ownership and corporate governance as we show that in the context of an emerging market corporate governance regulations are extremely important in attracting foreign investors. In the context of prevalence of weak enforcement (of existing regulations) in emerging markets, this study provides empirical support to the notion that strictly enforcing the existing governance regulations has the potential to attract higher level of foreign investment. The results suggest that policy measures aimed at attracting foreign investors in emerging markets should not only concentrate on adopting the best international corporate governance practices but should also signal strong enforcement of these regulations by assigning significant penalties for non-compliance.

The fluctuations in the rate of returns of the Bombay stock exchange are analyzed through wavelet transform. The fluctuations, in various time scales, naturally separated by the wavelets, are subjected to statistical analysis. The localization and multiresolution properties of the wavelets enable one to identify collective behaviour in the stock market and the extent of their influence at various time scales. The Gaussian nature of the rate of returns at certain scales and the periodic nature of the same, at other scales, are clearly brought out by this analysis. The utility of this approach for modeling purpose is also elucidated.

The adoption of information and communication technology (ICT) has made it possible to experience high levels of visibility, control and connectivity across the entire supply chain. However, in road transport logistics, wireless ICT applications like cellular networks, Wi-Fi, UMTS, 4G and WiMax have not entirely solved reliability and connectivity problems due to difficulties associated with limited range, scalability and security. This paper examines the feasibility of using a vehicular network technology, dedicated short range communication (DSRC), in a multimodal logistics environment as means of providing enhanced visibility and connectivity using a secure access architecture. The secure access architecture is necessary to provide a high degree of security to the detailed visibility involving road haulage feeding port operations using a centralised port service.  相似文献

Recent research provides evidence of a market premium accruing to firms that meet or beat analysts’ forecasts. We find similar results for our sample of firms. However, we also find a market premium for firms that meet or beat time-series forecasts, and that the highest market premium accrued to firms that meet or beat both analysts’ and time-series forecasts. These findings are supported by assessments of future financial performance over the next two subsequent years. Our findings are consistent with the notion that when time-series benchmark is used in conjunction with analysts’ forecasts, investors obtain a more reliable (i.e., less noisy) signal regarding whether firms have actually met or beaten market expectations.

This study is the first to use Johansen's cointegration approach for India in the analysis of the long‐term dynamics between the black and official exchange rates for the period 1953–1993. The study also estimates the long‐run elasticity of the official rate with respect to the black market rate. As monthly data over 40 years are used, and a more robust methodology is employed, the results are likely to be more reliable as compared with the earlier work on India. The results of our study suggest that while there is a long‐term relationship between the two rates, the direction of causality is from the black rate to the official exchange rate. This is plausible in the Indian context where policy has generally lagged behind events in the black market. The hypothesis of a constant black market premium is rejected, implying that there is a mismatch between the percentage change in the official exchange rate and the percentage change in the black market rate.  相似文献
