On a use of stratified sampling in optimal estimation

Summary Postulating an intra-class correlation structure for a finite population vector of variate — values optimal stratified and unstratified strategies for estimating the total are identified and relative efficiencies noted. Higher efficiency of stratified over unstratified sampling is demonstrated for usual estimators in ppswr case, in particular. In the uncorrelated case appropriately chosen two-stage strategies are observed to fare at par with optimal stratified ones.     

Trade Negotiations under Alternative Bargaining Structure

We build a bargaining model, in which a country (leader) decides whether or not to form a free trade agreement with other nations (followers), either through a sequential or a multilateral bargaining procedure. Unlike Aghion et al. ( 2007 , Journal of International Economics, 73, 1–30), in our specification of multilateral bargaining, the leader can collude with all those follower countries who agree to its offer. This has important implications for the choice of sequential and multilateral bargaining by the leader in presence of coalition externalities. Moreover, this bargaining procedure ensures that “stumbling block” equilibrium will never occur.     

Investigating the Pleasures of Sin: The Contingent Role of Arousal‐Seeking Disposition in Consumers' Evaluations of Vice and Virtue Product Offerings

Mixed bundles of vice and virtue are an increasingly important product category. However, many mixed bundles fail in the marketplace, and so it is important to examine how consumers evaluate such mixed bundles. This paper examines consumers' affective responses and consequent purchase evaluations for a mixed vice‐virtue bundle versus a pure vice product. Results of Study 1 show that purchase intentions are higher for a pure vice product versus a mixed product; also, increased purchase intentions are mediated by differences in arousal. Given that consumers differ in their arousal‐seeking dispositions, results of Studies 2 and 3 show that individual differences in arousal‐seeking moderate the relationship between product type (pure vice product vs. mixed product) and purchase intentions, with arousal‐seeking consumers preferring pure vice bundles, and arousal‐avoidant consumers preferring mixed bundles. This paper contributes to theory on mixed vice‐virtue bundles, and also provides pointers on how to better market mixed bundles.     

Targeting Child Labor in Debt Bondage: Evidence, Theory, and Policy Implications

Despite recent multilateral efforts to single out child laborin debt bondage as one of the worst forms of child labor, severalimportant questions have yet to be addressed: How pervasiveis the phenomenon? Are there systematic correlations betweenthe incidence of children in debt bondage and the economic,legislative, and financial development indicators of the economy?How does an understanding of these correlates affect the waynational and international policy measures aimed at targetingthis form of child labor are perceived? This article addresseseach of these questions. The empirical findings suggest strongcorrelation between the likelihood of the incidence of childlabor in debt bondage with the stage of development of an economy,the stage of financial development, and enforcement of corelabor rights. Building on this evidence, the article presentsa theoretical model that highlights the drawbacks and meritsof a number of policies aimed at putting checks on child laborin debt bondage.     

ON THE SHAREHOLDER WEALTH EFFECTS OF DEPOSIT INSURANCE PREMIUM REVISIONS ON LARGE,PUBLICLY TRADED COMMERCIAL BANKS

Evidence is provided from changes in deposit insurance premiums in the early 1990s on the validity of the premium absorption hypothesis and the premium shifting hypothesis. Analysis of abnormal market returns associated with deposit insurance events using a market‐model event‐study methodology suggests that reductions in deposit insurance premiums are associated with increases in the market value of banking organizations; conversely, increases in deposit insurance premiums are associated with decreases in market wealth. The largest banks in the sample and banks with low equity capital (and low risk‐based capital ratios) appear to be most affected. These results are generally consistent with the premium absorption hypothesis but inconsistent with the premium shifting hypothesis.     

Electronic word-of-mouth (eWOM) generation in new media platforms: The role of regulatory focus and collective dissonance

In this research, we examine the role of two motivational forces associated with creation of electronic word-of-mouth (eWOM): regulatory focus and collective dissonance. Our studies show that generation of eWOM is enhanced by regulatory fit, while traditional WOM is dominated by the negativity effect. In study 1A, we show that prevention-focused consumers produce stronger intentions to post eWOM when they undergo a negative compared to a positive service experience. In study 1B, we find that promotion-focused consumers are more likely to post eWOM in reaction to a positive service experience when one's self-construal is independent. The final study shows that due to collective dissonance, consumers have greater intentions to create eWOM when their experiences are inconsistent with others' postings. We discuss the implications of these results for the development and management of eWOM communication in virtual communities.     

A Comparison of Print Advertisements from the United States and France

Abstract

This study extends the research on cross-cultural advertising by comparing print advertisements from the United States and France in terms of emotional appeals, information content, and use of humor and sex. A content analysis of advertisements from two types of magazines from the United States and France revealed that French advertisements make greater use of emotional appeals, humor, and sex appeals. Advertisements from the United States were found to contain more information cues.

The influence of product knowledge and brand name on internal price standards and confidence

This study examines the influence of product knowledge (after adjusting for subjects' brand-specific price knowledge) and brand image (via the brand name) on estimates of internal price standards (i.e., lowest, average, and highest price estimates) for two categories of electronic products. The impact of differing levels of product knowledge on consumers' confidence in their internal price estimates is also studied. The hypothesized effect of brand image on price estimates was greater for novice consumers than for experts for one of the two product categories. In addition, confidence in price estimates was found to be higher for experts than for novices for both product categories. These findings suggest that the relationship between product knowledge and brand image should be considered when studying the impact of external reference price on internal price standards. © 1993 John Wiley & Sons, Inc.
