Third‐person perception and purchase behavior in response to various selling methods

Two studies investigated whether various tactics of personal selling that generate different levels of resistance also produce different degrees of third‐person perceptions. Furthermore, the studies compared third‐person perceptions to the actual influence on behavior. Study 1 showed that more direct and blatant selling methods produce more TPP. Study 2 showed that people tend to underestimate the influence of the more direct method, especially with regard to themselves. The study concludes by identifying the ideal selling method as one in which the customers are asked about their willingness to listen to the sales campaign before they are told about it. This method increases sales and creates satisfied customers. © 2009 Wiley Periodicals, Inc.     

Factors affecting the acquisition and transfer of novel attribute relationships to new product categories

This article investigates two factors posited to affect consumers' ability to learn a novel attribute relationship (e.g., “no pesticides → USDA organic symbol”) and apply this recently acquired knowledge when making judgments in a new product category. The first factor concerns the nature of the attribute encoding process and, in particular, whether it allows for comparison of examples. The second factor focuses on the relationship between the learning and transfer domains, and examines the influence of perceptual similarity (manipulated two ways: similarity in the elements comprising the attribute relationships, and similarity between the base and target domains) on the transfer process. Study 1 revealed a significant improvement in inter‐domain transfer when a relationship was learned in a multiple‐domain/multiple‐attribute learning environment over a single‐domain/single‐attribute environment. When attribute and domain diversity were examined separately (Study 2), it was found that attribute, but not domain, diversity produced the greatest improvements in transfer. Study 3 showed that the benefits of adding a perceptual similarity cue were most apparent when the transfer conditions were neither too easy (within domain and within attribute) nor too difficult (inter‐domain and inter‐attribute). © 2009 Wiley Periodicals, Inc.     

Does the Quality of Institutions Limit the MENA's Integration in the World Economy?

Using a large sample of countries over the 1990s, this paper examines the extent to which institutions’ functioning disables a greater participation of the Middle East and North Africa (MENA) in the world economy. It focuses on the impact on manufactured exports and FDI attractiveness and considers a broad index of political risk as well as indices targeted toward specific aspects of governance (corruption, government effectiveness and the rule of law). The results are robust to different econometric approaches and lend strong support to the hypothesis that the functioning of institutions may disable the participation of MENA countries in the world economy. They suggest that the impact of an improvement in the quality of institutions may result in a sensitive increase of FDI inflows and manufactured exports. That increase is comparable to the one resulting from liberalisation policies. Hence, although institutional reforms can take time, they deserve the necessary efforts given their outcomes as compared to other reforms.     

Basic Needs,Government Debt and Economic Growth

This paper investigates the relationships between basic needs and economic growth where the interactions between output, health, nutrition and education are explicitly simultaneous. We find a unidirectional relationship that improving basic welfare contributes strongly to labour productivity change, but a clear reverse causation only from growth to nutrition. There are substantial differences in the patterns of simultaneous interactions at different income and welfare levels. There are strong self‐reinforcing effects of literacy and debt service on poverty, making it difficult for poor countries to rectify their situation. Channelling resources towards improving health, education and nutrition could bring dramatic economic returns.

Estimation and testing of portfolio Value‐at‐Risk based on L‐comoment matrices

This study employs L‐comoments introduced by Serfling and Xiao (2007) into portfolio Value‐at‐Risk estimation through two models: the Cornish–Fisher expansion (Draper, N. R. & Tierney, D. E., 1973) and modified VaR (Zangari, P., 1996). Backtesting outcomes indicate that modified VaR outperforms and L‐comoments give better estimates of portfolio skewness and excess kurtosis than do classical central moments in modeling heavy‐tailed distributions. © 2009 Wiley Periodicals, Inc.

The incremental value of a futures hedge using realized volatility

A number of prior studies have developed a variety of multivariate volatility models to describe the joint distribution of spot and futures, and have applied the results to form the optimal futures hedge. In this study, the authors propose a new class of multivariate volatility models encompassing realized volatility (RV) estimates to estimate the risk‐minimizing hedge ratio, and compare the hedging performance of the proposed models with those generated by return‐based models. In an out‐of‐sample context with a daily rebalancing approach, based on an extensive set of statistical and economic performance measures, the empirical results show that improvement can be substantial when switching from daily to intraday. This essentially comes from the advantage that the intraday‐based RV potentially can provide more accurate daily covariance matrix estimates than RV utilizing daily prices. Finally, this study also analyzes the effect of hedge horizon on hedge ratio and hedging effectiveness for both the in‐sample and the out‐of‐sample data. © 2009 Wiley Periodicals, Inc.
