In this paper we show that flexible probability distribution functions, in addition to being able to capture stylized facts of financial returns, can be used to identify pure higher-order effects of investors' optimizing behavior. We employ the five-parameter weighted generalized beta of the second kind distribution—and other density functions nested within it—to determine the conditions under which risk averse, prudent and temperate agents are diversifiers in the standard portfolio choice theory. Within this framework, we illustrate through comparative statics the economic significance of higher-order moments in return distributions. 相似文献

The market power (or ‘competitive clout’) of a brand is an increasingly important component of modern marketing strategies. However, the factors that enhance a brand’s competitive clout (BCC) are poorly understood. This study therefore suggests an integrated model of BCC and three factors that are proposed to play a role in its formation: (i) consumer price sensitivity; (ii) brand market share; and (iii) consumer brand preferences. These variables are examined both individually and simultaneously to demonstrate the direct effect of each on BCC and how their inter-relationships contribute to BCC. In doing so, a two-step empirical analysis is conducted. First, two multinomial logit models provide an own- and a cross-price response matrix for a chosen set of competitive brands. Secondly, BCC is regressed against the variables of market share, intrinsic preferences, and price sensitivity using an interaction effects regression model. The results of the analysis show that market share is not the only way to increase BCC; in particular, consumer preferences, and especially pricing decisions, are shown to play a key role in developing a strong brand. 相似文献

In this paper, we study the production and dissemination of public knowledge goods, such as technological knowledge, generated by a network of voluntarily cooperating innovators. We develop a private-collective model of public knowledge production in networked innovation systems, where group-based social preferences have an impact on the coalition formation of developers. Our model builds on the large empirical literature on voluntary production of pooled public knowledge goods, including source code in communities of software developers or data provided to open access data repositories. Our analysis shows under which conditions social preferences, such as ‘group belonging’ or ‘peer approval’, influence the stable coalition size, as such rationalising several stylized facts emerging from large-scale surveys of open-source software developers, previously unaccounted for. Furthermore, heterogeneity of social preferences is added to the model to study the formation of stable but mixed coalitions. 相似文献

Using shopping diary survey data, we show that changing payment patterns is a challenging task; even when consumers have fallen in love with a new payment instrument, they find it hard to divorce from their old payment instrument. We find a discrepancy between how consumers prefer to pay and how they actually pay. Half of the consumers who prefer the debit card to cash don’t use the debit card to pay a majority of their point-of-sale transactions. Our regression results show that the habit of paying cash plays a significant role explaining the presence of a gap. 相似文献

In past years, beekeeping as an agricultural sector has become more organized, but there is still a gap in knowledge in considering consumer preferences for honey. The aim of the research was to determine consumer preferences for honey and their attitudes towards the Protected Designation of Origin (PDO) label. Also, in the article is presented the current situation regarding the honey market and legislation of the PDO label at the EU and national levels. The result of the empirical research carried out on a sample of 1008 respondents showed that they mostly prefer a mild flavour and brighter colour of honey. According to the type, most of the respondents prefer acacia rather than floral and meadow honeys or other types of honey. The most common method of honey purchase is directly from the producers (75%). The results of the Principle Component Analysis (PCA) showed that the most important attributes are the intrinsic attributes of the honey and that the most common reasons for purchasing and consuming honey are for its health and medical benefits. The obtained results fill the gap in knowledge regarding consumer preferences for honey in the Croatian market and can be useful for the creation of new honey-marketing strategies for local beekeepers. 相似文献

ABSTRACTSupport for open trade regimes varies. We analyze Japanese survey data on individuals' preferences for TPP, unilateral import liberalization, and East Asian economic integration, and compare factors influencing policy preferences. First, despite the massive negative campaigns against TPP, 42.8% of individuals support Japan’s participation in TPP, vs. 21.1% against. Second, economic factors do matter for an individual in determining his/her policy preference over TPP. Third, noneconomic factors such as gender, age, access to accurate information, and attachment to hometown also feature as determinants. Fourth, although preferences over TPP and other policy options are positively correlated, some factors decrease TPP support but do not undermine support for two other less-politicized policy options: lack of access to accurate information and some industry and regional TPP-specific factors. Criticism impacts negatively on FTA policy preferences. Finally, we discuss economic policy implications for relationships between China, Japan, and Korea.Abbreviations: FTA: Free trade agreement; JA: Japan agricultural cooperative; TPP: Trans-Pacific partnership agreement. 相似文献

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. 相似文献

We analyze the drivers of audience size and the number of questions asked in parallel sessions at the annual conference of the German Economics Association. We find that the location of the presentation is at least as important for the number of academics attending a talk as the combined effect of the person presenting and the paper presented. Being a presenter in a late morning session on the second day of a conference, close to the place where coffee is served, significantly increases the size of the audience. When it comes to asking questions, location becomes less important, but smaller rooms lead to more questions being asked. Younger researchers and very senior researchers attract more questions and comments. There are also interesting gender effects. Women attend research sessions more diligently than men, but seem to ask fewer questions than men. Men are less likely to attend presentations on health, education, welfare and development economics than women. Our findings suggest that strategic scheduling of sessions could ensure better participation at conferences. Moreover, different behaviors of men and women at conferences might also contribute to the lack of women in senior scientist positions. 相似文献

AbstractObjectives: Prader-Willi syndrome (PWS) is a rare genetic disorder associated with varying degrees of hyperphagia, obesity, intellectual disability, and anxiety across the affected individuals’ lifetimes. This study quantified caregiver priorities for potential treatment endpoints to identify unmet needs in PWS.Methods: The authors partnered with the International Consortium to Advance Clinical Trials for PWS (PWS-CTC) and a diverse stakeholder advisory board to develop a best–worst scaling instrument. Seven relevant endpoints were assessed using a balanced incomplete block design. Caregivers were asked to determine the most and least important of a sub-set of four endpoints in each task. Caregivers were recruited nationally though patient registries, email lists, and social media. Best–worst score was calculated to determine caregiver priorities; ranging from 0 (least important) to 10 (most important). A novel kernel-smoothing approach was used to analyze caregiver endpoint priority variations with relation to age of the PWS individual.Results: In total, 457 caregivers participated in the study. Respondents were mostly parents (97%), females (83%), and Caucasian (87%) who cared for a PWS individual ranging from 4–54 years. Caregivers value treatments addressing hyperphagia (score?=?7.08, SE?=?0.17) and anxiety (score?=?6.35, SE?=?0.16) as most important. Key variations in priorities were observed across age, including treatments targeting anxiety, temper outbursts, and intellectual functions.Conclusions: This study demonstrates that caregivers prioritize hyperphagia and, using a novel method, demonstrates that this is independent of the age of the person with PWS. This is even the case for parents of young children who have yet to experience hyperphagia, indicating that these results are not subject to a hypothetical bias. 相似文献

This work addresses the problem of optimal pricing and hedging of a European option on an illiquid asset Z using two proxies: a liquid asset S and a liquid European option on another liquid asset Y. We assume that the S-hedge is dynamic while the Y-hedge is static. Using the indifference pricing approach, we derive a Hamilton–Jacobi–Bellman equation for the value function. We solve this equation analytically (in quadrature) using an asymptotic expansion around the limit of perfect correlation between assets Y and Z. While in this paper we apply our framework to an incomplete market version of Merton’s credit-equity model, the same approach can be used for other asset classes (equity, commodity, FX, etc.), e.g. for pricing and hedging options with illiquid strikes or illiquid exotic options. 相似文献
