Daily outfit satisfaction: the effects of self and others' evaluation on satisfaction with what I wear today

This study investigated the satisfaction of the outfit which an individual chose to wear for the day by examining how self and others' evaluations influenced the outfit satisfaction and the intention to re‐wear. In addition, moderator variables (body satisfaction and body surveillance) that affected the effect of the evaluative factors upon satisfaction and behavioural intention were also examined. An online‐survey was conducted and the sample size used in the analysis was 349 in total. Using SPSS 18.0 and AMOS 18.0, structural equation modeling analysis and one‐way analysis of variance were implemented for hypothesis testing. The results showed that self‐evaluation as a perception of appropriateness of the outfit for that day and others' positive feedback increases outfit satisfaction. Appropriateness perception also had a significant impact on the intention to re‐wear. However, feedback from others on one's outfit did not have a significant direct effect on behavioural intention. Three‐way ANOVA was performed to verify the impact the feedback from others, body satisfaction, and body surveillance had on the respondent's intention to re‐wear, and a three‐way interaction effect was statistically significant. While individuals with high body satisfaction were likely to be confident about their appearance overall, the feedback from others did not impact their satisfaction. Individuals with low body satisfaction were influenced by others' feedback on their outfit. Individuals with high levels of body surveillance who sensitively monitored others' feedback especially displayed decreased intention to re‐wear when feedback from others on their outfit was negative. This research contributed to the deeper understanding of consumer's clothing behaviour at the post‐purchase stage. Enhanced understanding of lasting satisfaction and benefits pursued throughout the time while using the product would be essential in developing consumer‐centric marketing strategies.

泛北部湾区域贸易自由化问题研究

本文首先对贸易自由化问题进行了界定，然后就泛北部湾地区开展贸易自由化的各项因素进行了论述。一方面，笔者列举了一系列利于在该区域实现贸易自由化的潜在性因素；另一方面，笔者也注意到区域内各国基础设施条件和经济基础差异较大，贸易商品的层次不同、贸易间的关联度差以及各国在涉及国家经济安全，产业体系建立等贸易自由化政策方面所表现的不同倾向又为泛北部湾区域贸易自由化进程增添了障碍。本文在深入分析这些因素的基础上，从产业层次角度提出实现区域内贸易自由化的进程模式和方法。     

Predicting the sample mean by extreme order statistics

Summary This paper considers the prediction of the sample mean by extreme order statistics when the population distribution is known. The predictor and its mean square error are found. The problem is studied in details for the normal model.     

Equal opportunity and poverty reduction: How should aid be allocated?

This paper analyzes a model of aid allocation equalizing the opportunity between recipient countries to reach a common poverty reduction goal. We propose a fair and efficient aid allocation based on a multicriteria principle. The model considers structural handicaps in recipient countries in terms of lack of human capital and economic vulnerability, their initial poverty, and the natural gap between the growth rate required to reach a development goal and the observed one. We show that our proposed aid allocation favors poor and vulnerable countries with our multicriteria principle. It substantially differs from the observed allocation. Analyses also shed light on the impact of the donors' aversion to the low natural growth gap in recipient countries on the optimal aid allocation and the marginal efficiency of aid.     

Optimal consumption policies in illiquid markets

We investigate optimal consumption policies in the liquidity risk model introduced by Pham and Tankov (Math. Finance 18:613–627, 2008). Our main result is to derive smoothness C ¹ results for the value functions of the portfolio/consumption choice problem. As an important consequence, we can prove the existence of the optimal control (portfolio/consumption strategy) which we characterize both in feedback form in terms of the derivatives of the value functions and as the solution of a second-order ODE. Finally, numerical illustrations of the behavior of optimal consumption strategies between two trading dates are given.     

What If Immigrants Had Not Migrated?

A bstract .   Despite strong theoretical arguments and models about international migration, very few empirical studies rigorously test these arguments and models. The purpose of the present study is to analyze determinants and consequences for international migration, focusing particularly on the returns to post-hoc international migration. The present study compares residential well-being of Korean international migrants in the United States with that of their hypothetical well-being if they had not migrated. Our suggested models of the selectivity corrected returns to various characteristics for immigrants and nonimmigrants enable us to estimate the "opportunity well-being" of individuals and households; that is, the well-being of immigrants-had-they-stayed and of nonimmigrants-if-they-had-immigrated. The data for our analyses are drawn from the 1990 Korea Census Data and the Public Use Microdata Samples (PUMS) of the 1990 U.S. Census. In either case of migrants-had-they-stayed or of nonimmigrants-had-they-migrated, international migration to the United States has a significant and positive effect on the probability of homeownership, especially for women. The results show that the predicted probability of homeownership attainment increases as a result of migration by 15 percent to 16 percent for women and by 8 percent for men. The study concludes that migrating to the United States offers better opportunities for homeownership than staying in Korea does, particularly for women.     

Time Series Based Errors and Empirical Errors in Fertility Forecasts in the Nordic Countries*

We use ARCH time series models to derive model based prediction intervals for the Total Fertility Rate (TFR) in Norway, Sweden, Finland, and Denmark up to 2050. For the short term (5–10 yrs), expected TFR‐errors are compared with empirical forecast errors observed in historical population forecasts prepared by the statistical agencies in these countries since 1969. Medium‐term and long‐term (up to 50 years) errors are compared with error patterns based on so‐called naïve forecasts, i.e. forecasts that assume that recently observed TFR‐levels also apply for the future.     

The Dynamics of Commoditization in a Vietnamese Uplands Village, 1980–2000

Commodity markets have become key forces transforming upland livelihoods, social relations and landscapes in Vietnam and throughout Southeast Asia. This paper examines the processes of market formation and their effects on local livelihoods and social relations in a village of Vietnam's north-western uplands. The results indicate that villagers' reactions to new opportunities arising from decollectivization and market liberalization wove them into an increasingly intricate 'commodity web'. Differences among households widened as households with an initial advantage accumulated further advantages. Yet the relations governing access to land and product markets also provided a floor of subsistence for the disadvantaged. The findings demonstrate the need to interrogate commodity markets, investigate the practices and relations constituting them, and analyse how they distribute income and risks among the actors involved. The nature of commodity markets, together with the relations governing access to productive resources, influences processes of social differentiation in the uplands.
