In response to the growth of online shopping, consumer groups from around the world participated in two mystery shopping exercises. These exercises, conducted during the Christmas holiday seasons of 1998 and 2000, involved buying a variety of products from web sites located both domestically and abroad. A number of serious problems were identified within the research, especially lack of disclosure of key consumer information and failures in delivering goods and refunding consumers when goods were returned. The research has been used by consumer organizations to enhance consumer education and to lobby governmental and self-regulatory bodies for greater consumer protection in the online environment. 相似文献

The leading political–economy–of–trade models are virtually silent on two fundamental questions raised by Rodrik in 1995. Why are trade policies systematically biased against trade? And why are tariffs rather than more efficient production subsidies adopted to redistribute income? This paper shows that systematic political grass–root support for trade–restricting and inefficient tariffs emerges when the government has a revenue goal and collecting taxes is costly. Even if no tax instrument enjoys an advantage with respect to collection costs and the factor ownership distribution is unbiased, more people support tariffs than import or production subsidies. More generally, the presence of tax–collection costs creates a grass–root support bias for taxes over subsidies as instruments to redistribute income. 相似文献

Summary In this paper we consider a class of time discrete intertemporal optimization models in one dimension. We present a technique to construct intertemporal optimization models with nonconcave objective functions, such that the optimal policy function coincides with any pre-specifiedC
2 function. Our result is a variant of the approach presented in a seminal paper by Boldrin and Montrucchio (1986). Whereas they solved the inverse problem for the reduced form models, we address the different question of how to construct both reduced and primitive form models. Using our technique one can guarantee required qualitative properties not only in reduced, but also in primitive form. The fact that our constructed model has a single valued and continuous optimal policy is very important as, in general, nonconcave problems yield set valued optimal policy correspondences which are typically hard to analyze. To illustrate our constructive approach we apply it to a simple nonconcave model.We are grateful for the helpful comments of L. Montrucchio, K. Nishimura, T. Mitra and an anonymous referee.

We consider a differential game of R&D competition and explore the impact of rivalry on the firms' investment behavior over time. Using closed-loop strategies and hence allowing for strategic interactions among rival firms we show that R&D spending by the individual competitor is increased due to competition in the race for priority. This leads us to argue that competitive encounters enhance R&D activities at the same time as increasing efficiency in the race for a technological breakthrough. 相似文献

An important role of managers is to motivate subordinates. Monetaryrewards have been the focus of economic analysis. Managers alsouse other means to influence subordinates. If a manager canbetter assess the subordinate's ability than the subordinatehimself, and if ability and effort are complements, the managerfinds it hard not to overstate a junior's ability. Talk is cheap.We analyze under what conditions a manager can use organizationalpractices such as delegation and the selective provision ofattention to credibly communicate his assessment. We comparetheir desirability. Delegation is preferable in case the manager'sassessment is fairly accurate; attention is inescapable if itis inaccurate. 相似文献

This paper studies the relationship between bilateral trade patterns and opinions. It uses the Eurobarometer public opinion surveys published by the European Commission, which provide data on the share of the population in each EU15 member country in favour of each CEEC joining the EU. Our results first suggest that bilateral opinions have a statistically robust and relatively large effect on imports, even when standard and new covariates capturing proximity between countries are controlled for. We interpret this effect as reflecting a positive impact of “bilateral affinity” on trade patterns. We also show that it is possible to go some way towards explaining the variance in bilateral opinions among our sample. Last we provide some preliminary attempt to determine causality between bilateral opinions and imports. 相似文献

Analysts in a bank’s research department cover firms that have no relationship with the bank as well as companies in which
the bank has a strategic interest. Officially, banks must establish Chinese Walls around their research departments to allow
the analysts to work independently and to avoid the flow of insider information. We examine analyst behavior under long-term
bank-firm relationships using ownership data and analysts’ earnings per share forecasts for German companies from 1994 to
2001. We find evidence that is consistent with analysts reconciling their employers’ interests with their own career concerns.
They seem to use their information advantage strategically by releasing favorable and thereby more precise reports when the
market underestimates earnings. In order not to jeopardize the bank-client relationship, they suppress negative information
when the market is too optimistic. Combining situations where the market over- and underestimates earnings, we can replicate
the unconditional positive bias in analyst forecasts found in the previous literature. Despite the bias in affiliated analysts’
forecasts, they nonetheless selectively communicate valuable information to investors.
