Contingent Valuation Versus Choice Experiments: Estimating the Benefits of Environmentally Sensitive Areas in Scotland

This paper reports results from a study of the economic value of the conservation benefits of Environmentally Sensitive Areas (ESAs) in Scotland. The main novelty of the approach taken is in comparing two direct valuation methods, namely contingent valuation and choice experiments, to value these benefits. The Contingent Valuation Method (CVM) is well-established as a technique for valuing the sorts of landscape and wildlife enhancements associated with ESAs. The CVM experiment reported here uses a dichotomous choice format, and includes a new correction for part-whole bias. Choice experiments are much less used as an environmental valuation technique. We note several advantages of such experiments over CVM, and then report characteristic values and ‘programme values’ estimated using the method. This application brings to light some problems in applying the choice experiment method. Finally, we discuss the issue of benefits transfer in the context of these two approaches to valuation.     

Border tax adjustments and U.S. trade

This paper reports welfare and terms of trade effects from border adjustments in the indirect taxes used by major U.S. trading partners using a numerical general equilibrium model of world trade and production due to Whalley (1985). Where the United States is a net importer of manufactures (as with Japan and the EEC) the United States gains by having these countries administer taxes on a destination rather than an origin basis. This is because the taxes involved typically have higher rates on manufactured products, and a discriminatory origin basis tax with higher rates on exportables operates akin to an export tax.     

取悦客户的上上策

用户的忠实程度对于一个公司的兴衰成败意义重大,在经济发展前景不确定的情况下更是如此.对于一个公司来说,寻找一个新的用户并与之建立商业合作关系所需要的资金是维持一个现有用户的30倍～40倍,并且这种资金常常超越了公司的成本底线.因此,公司在维持与现有用户的商业合作关系上多投入5%的资金,就能够多得到25%～55%的利润回报.     

The Role of Beta and Size in the Cross-Section of European Stock Returns

This paper examines the ability of beta and size to explain cross-sectional variation in average returns in 12 European countries. We find that average stock returns are positively related to beta and negatively related to firm size. The beta premium is in part due to the fact that high beta countries outperform low beta countries. Within countries high beta stocks outperform low beta stocks only in January, not in other months. We reject the hypothesis that differences in average returns on size- and beta-sorted portfolios can be explained by market risk and exposure to the excess return of small over large stocks (SMB). Consistent with recent US evidence, we find that after controlling for size, there is no association between average returns and exposure to SMB.     

STOCK MARKET SEASONALITY AND TAXES: AN EXAMINATION OF THE TAX-LOSS SELLING HYPOTHESIS

Recent empirical studies have found evidence that supports the tax loss selling explanation of seasonal effects in stock returns. Using other test procedures, the present authors conclude that the support found in other studies is likely to be the result of spurious correlation between returns of stocks selected as tax-loss selling candidates and the January returns of these stocks.
