In 1983, the Greater London Council adopted a policy of 'Contract Compliance' designed to ensure that firms selling goods and services to the Council complied with its equal opportunity requirements. The initiative aroused wide interest and many other local authorities - 40 are known of to date - have been considering introducing such a policy. Although simple in essence, its execution can be complex and difficult. In April 1986, the Inner London Education Authority, a partner in the GLC policy, took over the Contract Compliance Unit following the GLCs abolition. Linda Smith explains the background to contract compliance, how the GLC, now ILEA, operates the policy; assesses its achievements and its significance and explores some of the lessons learnt in its three years of operation. 相似文献

A service orientation aims to provide professional and comprehensive service items to consumers in a sale or a non-sale situation, while an interaction orientation has the goal of creating good interaction ability with individual customers in order to maintain long-term, profitable customer relationships, and in the process obtaining valuable information about individual customers. These orientations build customer-centric operations and develop competitive advantages, thus enhancing firm performance and customer value. The main purpose of this study was to examine the relative and collective contributions of different strategic orientations on a firm's performance, with a focus on consumer–company identification. The structural equation model results indicate that (1) both service orientation and interaction orientation positively influence consumer–company identification and (2) interaction orientation results in higher perceived consumer identification. 相似文献

ABSTRACTWe find evidence of pervasive tariff evasion in the global data on trade from 1988 to 2015. Using over 35 million observations of data on import and export flows at the HS6 product category level, we find evidence of substantial underreporting of imports relative to export data on average and particularly when tariffs on product categories are high. These effects are stronger in more corrupt destination countries, as measured by the World Bank's Worldwide Governance Indicators [World Bank. 2016. Worldwide Governance Indicators. September 25, 2016]. In addition, evidence of tariff evasion increases significantly in economic downturns. We document these patterns in the global data and explore the welfare effects of this evasion by (1) putting a lower bound on the extent to which there are revenue losses from tariff evasion, and by (2) estimating the effects of corruption as measured by this indicator on global trade in a simple gravity model. We estimate that in total, revenue losses from tariff evasion are currently likely to exceed 400 to 670 million USD globally per year, and find that the effects of corruption on trade flows are ambiguous overall but change from weakly positive (‘grease the wheels’) to largely negative over the years in our sample. 相似文献

The downside risk in a leveraged stock position can be eliminatedby using stop-loss orders. The upside potential of such a positioncan be captured using contingent buy orders. The terminal payoffto this stop-loss start-gain strategy is identical to that ofa call option, but the strategy costs less initially. This articleresolves this paradox by showing that the strategy is not self-financingfor continuous stock-price processes of unbounded variation.The resolution of the paradox leads to a new decomposition ofan option's price into its intrinsic and time value. When thestock price follows geometric Brownian motion, this decompositionis proven to be mathematically equivalent to the Black-Scholes(1973) formula. 相似文献

As genetically modified (GM) products approach the market stage, the UK government and agro-food industry have faced a suspicious or hostile public. Since 1998 many retail chains have undertaken to exclude any GM-derived ingredients from their own-brand lines. This commercial blockage has intensified pressures for greater precaution, even for a moratorium on cultivating GM crops. Political protest has led to strategies for precautionary commercialization. Government and industry have cooperated to plan a ‘managed development’ of GM crops. Across the agricultural supply chain, industry has devised voluntary guidelines to ensure segregation of GM crops and to limit the spread of GM herbicide-tolerance. In particular UK regulators seek to test the risk that broad-spectrum herbicide sprays could damage wildlife habitats; they have broadened the advisory expertise accordingly. These measures open up the precautionary content to further debate, at both national and EU levels. Market-stage precautions establish a means to test claims that GM crops are environmentally-friendly products. By translating public concerns into broader risk-assessment criteria, the UK procedure involves critics in potentially influencing standards of scientific evidence and environmental harm. This social process has become a prerequisite for legitimizing commercial use. 相似文献

The Variance Gamma Process and Option Pricing 总被引:21,自引:0,他引:21
A three parameter stochastic process, termed the variance gamma process, that generalizes Brownian motion is developed as a model for the dynamics of log stock prices. The process is obtained by evaluating Brownian motion with drift at a random time given by a gamma process. The two additional parameters are the drift of the Brownian motion and the volatility of the time change. These additional parameters provide control over the skewness and kurtosis of the return distribution. Closed forms are obtained for the return density and the prices of European options. The statistical and risk neutral densities are estimated for data on the S & P500 Index and the prices of options on this Index. It is observed that the statistical density is symmetric with some kurtosis, while the risk neutral density is negatively skewed with a larger kurtosis. The additional parameters also correct for pricing biases of the Black Scholes model that is a parametric special case of the option pricing model developed here. 相似文献

This study demonstrates that in contrast to prior research findings on short-term stock returns, long-term stock returns are
positively correlated with inflation. In addition, within the context of a more complete explanatory model, long-term stock
returns are found to be negatively related to changes in long-term interest rates and negatively related to beginning price
to earnings ratios. The significance of these variables in explaining almost all the time series variation in long-term stock
returns demonstrates that changes in stock values are well explained by theory. 相似文献
