Indian industry is under pricing pressure after the government cut tariffs in a phased manner as per the WTO agreements. In order to be competitive, the consensus opinion in government, academics and industry is the implementation of a VAT in India. The paper evaluates the welfare implications of a VAT in the static and a sequentially dynamic context after accounting for the political and administrative constraints facing the Indian government in implementing a VAT. Replacing the old indirect tax structure with a VAT is welfare worsening. The increase in final consumer prices on account of reduced tax base leads to higher price of essentials, causing welfare loss. Zero rating v/s exemption plays an important role on welfare, with lower welfare loss if essential commodities are exempt from VAT. Agriculture sector unambiguously plays a crucial role in welfare.  相似文献

We investigate bank stocks'sensitivity to changes in interest rates and the factors affecting this sensitivity. We focus on whether the exposure of commercial banks to interest rate risk is conditioned on certain balance sheet and income statement ratios. We find a significantly negative relation between bank stock returns and changes in interest rates over the period 1991–1996. We also find that bank characteristics measured from basic financial statement information explain bank stocks'sensitivity to interest rate changes. These results suggest that bank managers, analysts, and regulators can use this information to assess the relative risk exposure of banks.  相似文献

Initial margin requirements represent: (1) a cost impediment to the wealth constrained investor and (2) a potential way of mitigating excessive volatility. However, prior empirical research finds that margins are not an effective tool in reducing volatility. We consider the possibility that margins primarily affect certain stocks and investors. Specifically, we test whether margins affect individuals who, as a group, we believe to be the investors most affected when margin requirements change. Our initial empirical tests, however, do not support this contention.  相似文献

This paper employed eleven data series which consist of stocks, bonds, bills, equity premiums, term premiums, and various default premiums to investigate whether January seasonality reported in existing literature is robust across different states of the economy as this has important trading implications. For the periods 1926–1990, small stocks, small stock premiums, low grade bonds, and default premiums (spread between high grade, low grade and government bonds) reveal January seasonality and that the seasonality is robust across different states of the economy except for low grade bond returns and default premiums. January seasonality for low grade bond returns and low grade bond default premiums are primarily driven by results found during periods of economic expansion. Overall, January seasonality is more evident during the economic expansion periods although the magnitude of default premiums is larger during periods of economic contraction. Furthermore, prior findings of strong summer equity returns are primarily driven by the results found during the periods of economic contraction. It is also found that equity returns are generally higher during periods of economic expansion.  相似文献

This paper estimates the private returns to human capital in Pakistani rural labour markets. The rich data used permit inclusion of several dimensions of human capital and control for endogeneity resulting from investment in human capital. The results suggest that, without data on determinants of human capital, it would not be possible to disentangle the separate effect of each dimension of human capital on wage differentials nor to distinguish human capital explanations for wage differentials from signalling and credentialist models. With control for endogeneity of human capital and selectivity into wage employment, cognitive achievement, but not schooling attainment separate from cognitive achievement nor long-run health status, affects wage differentials.  相似文献

Cash settlement of derivative contracts makes them susceptible to manipulation by traders who expect to close large positions upon final settlement. Cash settlement also increases underlying volatility when hedgers unwind their hedges if they have no incentives to control their trading costs. Limits on the positions that traders can carry into final settlement can be used to mitigate associated economic inefficiencies when surveillance is insufficient. This article develops a model that regulators can use to set these limits that is based upon microstructure theory. The empirical findings indicate that existing position limits are largely inconsistent with those suggested by the model. © 2005 Wiley Periodicals, Inc. Jrl Fut Mark 25:945–965, 2005  相似文献

Aggregate agricultural commodity demand parameters are estimated, based on an application of the Deaton and Muellbauer Almost Ideal Demand System to a seventeen year Indonesian time-series data set of prices, expenditures and consumption availability. The statistical results are generally significant and correctly signed. The revealed demand relationships imply that the Indonesian food Staples are normal goods. Expenditure elasticities are higher for the higher value foodstuffs than for the lower value starchy staples. Furthermore, the demand for rice has become highly inelastic to both own and cross-price interventions. This implies that rice price interventions will require a high degree of fine-tuning in order to stabilise prices effectively, and that low urban rice prices cannot be regarded as an appropriate, or even second best policy instrument for improving nutritional status.

A high degree of Substitution between rice and secondary food crops, and amongst groups of secondary food crops, is identified. The significance of the cross-price elasticities for the secondary food crops suggests that single-market interventions will have non-trivial budget-mediated effects in other commodity markets. The management of a multi-commodity food policy requires that the spillover effects from commodity pricing policy must be taken into account in order to optimise the effects of price policy interventions.  相似文献
