Consumers' awareness,acceptance and attitudes towards functional foods in Turkey

The aim of the present study was to investigate consumers' awareness, acceptance and attitudes towards functional foods in Turkey. Eight hundred and eight people participated in this study: aged between 20 and 80 years, 38.5% were male and 61.5% were female. Participants were given a questionnaire and were asked to fill it in by themselves to minimize the influence of the interviewer. Results indicated that socio‐demographic characteristics such as age, education level and income level are important indicators of consumers' awareness and consumption of functional food. The results show that the female respondents were 2.987 times more aware of functional food than the male respondents. Similarly, the likelihood of respondents having awareness of functional food was 1.431 times greater among those who had a higher educational level than among those with a lower educational level. Consumers who used vitamin supplements were 1.228 times more aware of functional food than other consumers. The results show that older respondents were 3.395 times more aware of functional food than younger respondents. Respondents with a history of familial diseases were more likely than others to have consumed margarine with plant sterol, fruit juices fortified with vitamin C, and breakfast cereals fortified with vitamins and minerals. Those with a diet‐related problem were more likely to have consumed cholesterol‐lowering products than those without a problem. As a conclusion, this study has shown that socio‐demographic characteristics such as age, education and income levels, and prices are important indicators that influence consumers' awareness and consumption of functional food. These results suggest that this type of knowledge could affect consumers' interest in functional foods, and therefore educational strategies might be necessary to encourage the consumption of functional foods.     

Prepayment and future cross-buying: an exploratory analysis

Recent research has provided important insights on consumers’ preferences for prepayment mechanisms and on its impact on consumption of a given product or service. However, little is known about how prepayment influences future purchases of goods and services. We consider this question in a contractual setting within the services industry, involving different purchasing decisions over time. Based on a large-scale empirical test, we find that prepay customers make fewer changes to their cross-buying levels (i.e., the number of different services they buy from the company) from one contractual period to another, and that this effect is more salient for the firm's new customers. We propose possible explanatory mechanisms for this effect. For instance, based on mental budgeting theory, we suggest that prepayment customers may set mental budgets and track expenditures against this budget leading them to resist further investments. Alternatively, prepayment customers may be more certain about their consumption behavior leading to fewer changes over time.

Optimal portfolio choice in real terms: Measuring the benefits of TIPS

In this paper we solve an optimal portfolio choice problem to measure the benefits of Treasury Inflation Indexed Securities (TIPS) to investors concerned with maximizing real wealth. We show how the introduction of a real riskless asset completes the investor asset space, by contrasting optimal portfolio allocations with and without such assets. We use historical data to quantify gains from availability of TIPS in the presence of other asset classes such as equities, commodities, and real estate. We draw a distinction between buy-and-hold long-term investors for whom TIPS fully displace nominal risk-free assets and short-term investors for whom TIPS improve the investment opportunity set of real returns. Finally, we show how gains from TIPS are tempered by the availability of alternative assets that covary with inflation, such as gold and real estate.     

Expatriation: Traditional criticisms and international careers: Introducing the special issue

In this introduction to our special issue, we will first seek to discuss the extent to which recent expatriation research and literature is still subject to earlier criticisms. Second, we will discuss the future research needs concerning the theme of this special issue, international careers, briefly reviewing the dominating research theme within the international career context (i.e., the career impacts of international assignment) and suggesting some future research areas. After that, we will offer a particularly promising new avenue for future research: the new forms of international work. We will conclude by summarizing the articles for this special issue and illustrate how they fit within this new avenue. © 2010 Wiley Periodicals, Inc.     

法律与国家的逻辑关系

本文以现实存在的法与国家为切入点，论证了分析实证视野下国家对法律的先决关系，再以自然正义的抽象精神为背景，探讨了二元论揭示的理性与正义的回归，最后以辨证分析得出结论：法律作为人类终极追求的抽象精神的体现，在国家的实际运行中起着指导的作用，但人类的共同价值又不可避免的局限在特定历史条件下的国家语境中。     

Revealed preferences for portfolio selection – does skewness matter?

In this article, we consider the portfolio selection problem as a Bayesian decision problem. We compare the traditional mean–variance and mean–variance–skewness efficient portfolios. We develop bi-level programming problem to investigate the market’s preference for risk by using observed (market) weights. Numerical experiments are conducted on a portfolio formed by the 30 stocks in the Dow Jones Industrial Average. Numerical results show that the market’s preferences are better explained when skewness is included.     

The Gender Contract under Neoliberalism: Palestinian-Israeli Women's Labor Force Participation

This paper interprets the pressure to raise Palestinian-Israeli women’s labor force participation within the unfolding neoliberal project in Israel, arguing that women’s stalled workforce integration reflects embedded economic rationality. Poor infrastructure and discriminatory policies, combined with Israel’s rapid economic privatization, set contradictory expectations for Palestinian-Israeli women: their opportunity-cost calculations include entitlements to economic protection alongside obligations to provide expenditure-saving domestic labor. Yet growing pressure and desire to join the paid workforce suggest that the gender contract may be changing. This cultural schema, which links women’s economic strategizing to their sense of feminine propriety, is transforming as part of a broader transition to a market-led gender regime, with the paradoxical effect of encouraging women’s employment while simultaneously impoverishing them. By dwelling on the dialectics of culture and the structure of work opportunities, and women’s agency, this paper aims to resolves an impasse in the current debate on women’s low workforce participation.     

社会融资规模作为金融宏观调控中介目标的适用性分析

本文采用2002年第1季度至2012年第2季度数据考察了三个备选的金融宏观中介目标——社会融资规模、人民币贷款和广义货币M2。图形直观分析、脉冲响应分析以及协整关系分析三种方法均表明：第一,M2不是一个理想的中介目标。第二,不论从与实体经济还是与物价指数的关系看、从中短期影响还是从长期均衡关系看,社会融资规模在三个中介目标中表现最好,建议我国以社会融资规模作为金融宏观调控的中介目标。第三,实体经济较物价指数更快受到金融宏观调控政策（中介目标变量）的影响。调控发生后,实体经济约5季后正效应达到最大,物价指数约在2至3年间响应达到最大。政策时滞对制定前瞻性的金融宏观政策具有一定指导意义。
