上市公司高管过度自信对现金股利政策的影响

抛弃经典财务理论中理性经理人的假设,将规范研究与实证研究相结合,以2006—2010年我国沪深两市A股上市公司作为研究样本,用管理者的相对薪酬、持股状况和实施并购次数构建综合指标来衡量公司高管的过度自信程度,从公司高管过度自信的视角重新审视上市公司的现金股利分配行为。研究结果表明:管理者过度自信的上市公司倾向于少发放现金股利来增强内部融资;上市公司的成长性越强,管理者的过度自信对现金股利分配决策的影响越显著。     

消费者对可追溯牛肉的认知及其影响因素分析——基于结构方程模型

利用针对北京市城区消费者的402份调查问卷数据,运用结构方程模型,分析了消费者对可追溯牛肉的认知及其影响因素。结果显示,消费者对可追溯牛肉的认知水平较低,但消费者在信息强化后对可追溯牛肉安全性的评价较高;信息搜集和经济文化因素显著影响消费者对可追溯牛肉的认知水平,风险感知、牛肉重要性和经济文化因素显著影响消费者对可追溯牛肉的认知内容,但认知水平并不显著影响认知内容。最后提出相关对策建议。     

A bibliometric study of financial risk literature: a historic approach

This study probes into the development of financial risk literatures through the perspective of bibliometrics. The research samples were collected from the relevant international financial business bibliographic databases. A total of 2727 entries in a span of 29 years from 1970 to 2009 were collected and the results are summarized as follows: (1) the financial risk literatures under influence of the financial turmoil in Asia achieved substantial growth from 1997 to 1998 and an exponential growth curve during the global financial turmoil from 2007 to 2009; (2) the literatures were mainly journals and articles written in English; (3) the United States ranked first in sector productivity; (4) the author productivity of the financial risks was consistent with the Lotka's Law and (5) the document types of the financial risk literatures were mostly dissertation papers on economics and business.     

Asymmetries and interdependencies in time use between Italian parents

In recent decades, changes in parents’ attitudes towards the importance of spending time with children to optimize their future behaviour and cognitive development have greatly affected patterns of time allocation among both working and nonworking parents in all developed countries. We compare the two waves of the Italian Time Use dataset (1988 and 2002) to analyse how family time allocation changed over time in a country that was undergoing a marked increase in female employment rate and a continuous decline in total fertility rate. We focus especially on how parents’ time with their children depends on their employment status and household characteristics. Using a simultaneous sequential approach, we consider links among the different time uses of individuals and correlations with spouses’ decisions. We find that wives’ time at work time strongly influences the time spent by both spouses with their children in 2002, but not in 1988. Fathers were much more involved in childcare and rearing in 2002 than in 1988. In general, as women's work time increased, substitutes for their childcare time were found within the household (fathers or other co-resident adults).     

Are auction revenues affected by rising art buyers’ premia? The case of early American art

The steady rise in the premiums charged to art buyers at auction (above hammer price) has been underway since 1992. This article, using a stable and bounded sample of repeat purchase of American works created before 1950, reveals that this tact has reduced hammer prices for that art. However, renewed and hyper-competitive efforts to bring more and higher quality art to market by the two main houses, Sotheby’s and Christie’s, have resulted in general profitability. Nevertheless, we calculate that a rise in buyers’ premia at Sotheby’s, a publically traded company, has reduced revenues and profits below their potential in the absence of such increases.     

The effects of multilateral trading systems on risk and return in equity markets

The event study methodology of Brown and Warner (1985) is adopted and augmented to evaluate the effect of the launch of multilateral trading systems on risk and return in equity markets. The methodology is supplemented with various techniques, such as the nonparametric ranking test and kernel regression, to find out if announcements about the introduction of Chi-X Australia generated abnormal returns (ARs). Asset pricing models are fitted with interaction variables, while GARCH, threshold ARCH (TARCH), exponential GARCH (EGARCH) and power-ARCH (PARCH) are used to determine changes in systematic risk. We find evidence in favour of Fisher’s separation theorem and detect a new market anomaly, which we call the ‘Fisher market anomaly’. Our results show that Chi-X system testings affect ARs. Consistent with the adaptive expectations theory, we confirm that the first announcement about the launch of Chi-X affected systematic risk the most. In addition, we identify industry and firm effects in risk analysis.     

Impulse response analysis and Orcutt’s hypothesis in trade: evidence from developing countries

Orcutt’s hypothesis in international economics implies that trade flows respond to exchange rate changes faster than to changes in relative prices. Most previous studies used import and export demand models and tested the hypothesis by imposing and comparing lag lengths on the exchange rate and relative prices. One recent study, however, employed impulse response of trade flows to one SD shock to the nominal exchange rate and one SD shock to relative prices and tested the Orcutt’s hypothesis for several industrial countries. In this article we follow this study and test the hypothesis for six developing countries using impulse response analysis. Like the other study for industrial countries, we do not find much support for the hypothesis.     

Skidelsky's Keynes: a review essay

Abstract

The paper examines the pro-work doctrines of four writers who were connected with the ‘utopian’ and ‘romantic’ critique of classical economics in the nineteenth century. These authors are Charles Fourier, Thomas Carlyle, John Ruskin, and William Morris. All four argued that the problem of work aversion stemmed from the existing institutions of capitalist society, and could be overcome by the creation of an alternative system of production. Their aim was to create a future society in which work could be experienced as a positive activity. The paper argues that the views of the aforementioned authors provided an important counterchallenge to the classical economists' conception of work as a disutility.     

Ugo Broggi: a precursor in mathematical economics

The concern for the existence of solution to the Walras - Cassel model is usually dated at the beginning of the 1930s, and one decade later the proof of existence of utility function. Ugo Broggi, however, posed both issues in 1923 and 1919, respectively, and even hinted at modern ways of solving them. He was an outstanding mathematician, a former disciple of David Hilbert and collaborator with the Giornale degli Economisti. Broggi's achievements are also linked to a critical reading of Osorio's treatise on Paretian economics.     

Another Graphical Proof of Arrow's Impossibility Theorem

Arrow's (1951) Impossibility Theorem is the idea that, given several well-known assumptions, the social orderings of particular alternatives that are meant to reflect individuals' preferences must match the preferences of an arbitrary individual (the dictator). A social-choice rule other than dictatorship is impossible. Following from Fountain (2000), the author presents another graphical proof of the theorem that is intended to be more accessible to students and teachers of economics. The principal strength of this approach is that the patterns of agreements and conflicts over all possible combinations of two individuals' rankings of alternatives are transparent; appreciating these patterns is the key to intuitively understanding Arrow's theorem. A self-test for readers (or a classroom exercise for students) is included.
