Recent evidence on the performance and riskiness of contrarian portfolios

The paper assesses the most recent performance, persistence and riskiness of contrarian portfolios. Evidence from the major world and European market of France shows that such portfolios appear profitable on average, but their performance is not persistent from one holding period to the next; hence there exist inherent risks, especially for investors that remain in markets for up to two consecutive investment periods. These risks, as measured by the CAPM (traditional, and less traditional versions that are meant to capture timing) and the Fama–French model, are not systematic and they are not related to market timing. Overall, taking only long positions in normal markets and hedged positions following market shocks seems to be the most promising route for contrarians in France.     

Estudio de los factores de compra de productos retro y segmentación del mercado potencial retro

This paper aims to analyze the behavior of potential retro products buyers. A bibliographical review has allowed defining the motives to buy this type of products. However, it should be emphasized that there is scarcely any quantitative information on the reasons to purchase and the segmentation of the potential retro product market. Using the data collected by means of a survey, a factor analysis and a cluster analysis have been performed. As a result, there are three factors of retro product purchase: characteristics of product, present differentiation feelings and past feelings. Furthermore, the existence of two differentiated segments has been detected: emotive consumer and commercial consumer.     

Non-parametric and parametric bootstrap techniques for age-to-age development factor methods in stochastic claims reserving

In the literature, one of the main objects of stochastic claims reserving is to find models underlying the chain-ladder method in order to analyze the variability of the outstanding claims, either analytically or by bootstrapping. In bootstrapping these models are used to find a full predictive distribution of the claims reserve, even though there is a long tradition of actuaries calculating the reserve estimate according to more complex algorithms than the chain-ladder, without explicit reference to an underlying model. In this paper we investigate existing bootstrap techniques and suggest two alternative bootstrap procedures, one non-parametric and one parametric, by which the predictive distribution of the claims reserve can be found for other age-to-age development factor methods than the chain-ladder, using some rather mild model assumptions. For illustration, the procedures are applied to three different development triangles.     

Employment protection and productivity: evidence from firm-level panel data in Japan

Recent developments in the literature on Employment Protection Legislation (EPL) have revealed that changing the stringency of employment protection can lead to extensive consequences outside the labour market, by affecting firms’ production decisions or workers’ commitment levels. This article provides the first empirical evaluation of the comprehensive effect of restrictions on firing employees in Japan, by exploiting the variations in court decisions. We find that judgements lenient to workers significantly reduce firms’ total-factor productivity growth rate. The effect on capital is mixed and inconclusive, although we obtain modest evidence that an increase in firing costs induces a negative scale effect on capital inputs.     

Economic structure and factor payments

There is a growing body of evidence that the labour payment share in national income varies across countries and over time, suggesting that the popular aggregate Cobb–Douglas production function may not capture income share dynamics. There remains conflicting evidence on the importance of natural resource rents among low income economies and on estimates of the rate of return to produced capital. This paper focuses on the structural differences among countries, confirming the importance of the agriculture sector in estimates of labour and land’s share of factor income based on 81 countries at diverse levels of economic development in the year 2005. I find that cross-country data are best modelled by a CES production function with an elasticity of substitution of 0.8 and that many low income countries have a higher return to capital than the United States.     

Pushing Economies (and Students) Outside the Factor Price Equalization Zone

Despite overwhelming empirical evidence of the failure of factor price equalization, most teaching of international trade theory (even at the graduate level) assumes that economies are incompletely specialized and that factor price equalization holds. The behavior of trading economies in the absence of factor price equalization is not well understood, and some major textbook treatments err. The authors map regions of specialization and diversification for standard competitive economies and show how outputs, goods, and factor prices change as economies move within and across different regions of diversification and specialization. Two examples of how the analysis can enrich graduate-level trade teaching are given: the substitutability of goods trade and factor movements, and debates over the trade and inequality.     

消费者接受淘宝在线评论的影响因素研究——以大学生为例

基于消费者心理学、霍夫兰德说服模型和大学生心理,通过文献研究法和调查问卷法,研究消费者在网购方面的涉入度、评论数量、评论内容和质量、评论者资信度、价格折扣以及消费者接受淘宝网在线评论程度与带来的影响,其结果显示:评论者资信度与因变量无显著相关性,其他自变量均对消费者接受淘宝网在线评论程度则具有显著正面影响。研究消费者接受淘宝在线评论的影响因素,有利于消费者对自己行为有更深了解,以己推人,在购买商品后,知道如何给出更有效的参考评论;而对商家而言,根据在线评论预测销售,可及时采取有效战略措施,加强虚拟网络中人与人之间的沟通,让消费者对商品有更全面的了解,从而适当削弱柠檬市场效应。     

Are consumers' financial needs and values common across cultures? Evidence from six countries

Are consumers' financial needs, and financial values, the same or different across cultures? Two studies, with student (Study 1; n = 988) and non‐student (Study 2; n = 959) participants, explore the extent of equivalence, across six countries (Brazil, Russia, China, Taiwan, Tunisia and US), in financial need belief, and financial value, measurement models. The financial need beliefs, derived from self‐determination theory (SDT) principles, include financial self‐efficacy, financial autonomy, financial community trust and support; the financial values include materialism and financial altruism. Both the financial need and financial value constructs evidence configural invariance (similar factor structure), and factor invariance among student but not non‐student samples. The financial need constructs evidence full, and the financial value constructs evidence partial, metric (factor loading) invariance. Factor covariance invariance obtains for the financial need beliefs constructs but not the financial value constructs. Finally, neither financial need nor financial value constructs evidence scalar (intercept) invariance. These results provide partial support for extending SDT's hypothesis of universal human needs to the financial domain. In contrast, the financial value constructs of altruism and materialism are largely instable across cultures, suggesting that consumer views of giving, and the role of wealth in social status, differ between countries.     

Exploring Foreign Tourists’ Image of Tanzania: A Factorial Analysis Approach

Abstract

In the last decade, the economy of African continent and Tanzania in particular has witnessed a business boom of the tourism sector. While the sector has continued to grow and become a dependable source of direct and indirect employment to youths in urban and rural areas, the sector has been awash with challenges. These challenges include terrorism attacks, energy crises and poor infrastructure. However, the impact of these challenges on the image of Tanzania as a tourist destination has not received the deserved attention. This study explores the perception of visitors towards Tanzania as a tourist destination after they have completed their tourist visit. This study employs factor analysis technique to explore country destination image. Questionnaires were administered to visitors at some of the tourists’ hotels and Julius Kamabarage Nyerere International Airport (as a major exit point) in the country. Frontline employees, various tourist sites and access to services emerged to be strong tourist destination image factors. This implies that the efforts of marketing tourism destination should focus on promoting all the sites the country has.
