This paper shows that a manufacturer may benefit from parallel trade. In addition to an intuitive condition about the effect of demand shocks, this occurs when competitive retailers must order inventories before they know the realization of demand and for products whose sale value drops at the end of the demand period. For these types of products, letting retailers trade unsold inventories generally results in larger orders placed with the manufacturer and higher manufacturer profit. The model provides a simple explanation as to why the volume of parallel trade is now very large and accepted by manufacturers for some products such as automobiles, clothes, toys, consumer electronics, musical recordings, cosmetics and perfumes. 相似文献

The removal of the internal frontiers within the EC will tend to have a negative effect on trade relations between EC and CMEA countries. The implications of 1992 for trade patterns between the EC and the CMEA are examined in the following article and the role which future EC trade policy could play here is outlined. 相似文献

This paper presents an inductive study that shows how collaborative prototyping across functional, hierarchical, and organizational boundaries can improve the overall prototyping process. Our combined action research and case study approach provides new insights into how collaborative prototyping can provide a platform for prototype‐driven problem solving in early new product development (NPD). Our findings have important implications for how to facilitate multistakeholder collaboration in prototyping and problem solving, and more generally for how to organize collaborative and open innovation processes. Our analysis reveals two levels of prototyping. Besides the more formal managerial level, we identify the informal designer level, where the actual practice of prototyping takes place. On this level, collaborative prototyping transforms the act of prototyping from an activity belonging exclusively to the domain of design engineers to an activity integral to NPD, with participants from within the organization (different functions and managers) and from outside (consultants and users). In effect, this collapses the discrete steps in the prototyping process (at the managerial level) to an essentially continuous process of iterative problem solving (at the designer level) that is centered around the collaborative prototype, which allows participants to see their suggestions implemented and exposing them to the design constraints. The study, moreover, shows how, at various stages of the prototyping process, the actual prototype was used as a tool for communication or development, thus serving as a platform for the cross‐fertilization of knowledge. In this way, collaborative prototyping leads to a better balance between functionality and usability; it translates usability problems into design changes, and it detects emerging usability problems through active engagement and experimentation. As such, the collaborative prototype acts as a boundary object to represent, understand, and transform knowledge across functional, hierarchical, and organizational boundaries. Our study also identifies some constraints in involving the appropriate stakeholders at the right time. The paper specifically elaborates on the role of users in collaborative prototyping, which is important in order to cover all phases of the problem‐solving cycle but triggers an interesting challenge due to the “reverse empathy” that a user may develop for the design constraints—parallel to the designer empathy for the user context. Finally, our study shows that despite the continuous nature of the (designer) practice of prototyping, there are certain windows of opportunities (at the managerial level) during which the collaborative prototyping approach actually leads to changes in the product design. 相似文献

Although speculative activity is central to black markets for currency, the out‐of‐sample performance of structural models in those settings is unknown. We substantially update the literature on empirical determinants of black market rates and evaluate the out‐of‐sample performance of linear models and non‐parametric Bayesian treed Gaussian process (BTGP) models against the random walk benchmark. Fundamentals‐based models outperform the benchmark in out‐of‐sample prediction accuracy and trading rule profitability measures given future values of fundamentals. In simulated real‐time trading exercises, however, the BTGP achieves superior realized profitability, accuracy and market timing, while linear models do no better than a random walk.

We study the money flows into and out of socially responsible investment (SRI) funds around the world. In their investment decisions, investors in SRI funds may be more concerned with ethical or social issues than with fund performance. Therefore, SRI money flows are less related to past fund returns. Ethical money is less sensitive to past negative returns than are conventional fund flows, especially when SRI funds primarily use negative or Sin/Ethical screens. Social attributes of SRI funds weaken the relation between money inflows and past positive returns. However, money flows into funds with environmental screens are more sensitive to past positive returns than are conventional fund flows. Stock picking based on in-house SRI research increases the money flows. These results give evidence on the role of nonfinancial attributes, which induce heterogeneity of investor clienteles within SRI funds. We find no evidence of a smart money effect, as the funds that receive more inflows neither outperform nor underperform their benchmarks or conventional funds. 相似文献

Despite broad public support for wind energy in principle, windfarm developments are often met with local opposition. There is theoretical, case-based and anecdotal evidence to suggest that ‘the local’ is relevant for planning process outcomes, but the nature and extent of this relevance is not so clear. We embark on an initial exploration of local factors that, on aggregate, may be of relevance to planning outcomes of proposed windfarms in rural England. Applying a broad scanning approach we use an existing small area GIS dataset of 117 variables related to education, health, demography, employment and housing. We identify a number of strong associations, and discuss to what extent these make sense in the light of existing literature on environmental equity and social capital, or throw up questions for further study. Notwithstanding the methodological caveats of this explorative study, and the scope for more in-depth analysis, our findings suggests that beyond the myriad of individual planning cases, the emerging landscape of wind energy development in England is markedly uneven, and sometimes inequitable. Evidence of the latter emerges notably through the strong significance of local democratic deficit (i.e. low voter turn-out) as a predictor of a ‘positive’ planning outcome for windfarms and the further strengthening of predictive associations at the appeal stage. 相似文献

Wundumgebung und Wundauflagen - Die wundumgebende Haut, sofern sie intakt
ist, hat eigentlich keinen direkten Einfluss auf die Wundheilung, da aber die Wundauflagen
oder der Sekund?rverband auf der wundumgebenden Haut fixiert wird, ist die
Beurteilung und Schutz dieser Hautareale für die Wundheilung von Bedeutung. 相似文献
