A lottery-preference-based explanation of realized kurtosis puzzle in Chinese stock market

High kurtosis corresponds to fat tails on both sides and under risk-aversion assumption investors’ dislike of left-tail loss outweighs their preference for right-tail gain. Therefore, high kurtosis characteristic of stock should predict high expected returns. However, the high-frequency-data-based empirical results on Chinese stock market are just the opposite, which we refer to as the ‘realized kurtosis puzzle’. Using the double sorts and firm-level cross-sectional regression methods, we further demonstrate investors’ preference for lottery-like stocks or lottery preference is key to solve the puzzle. Our further empirical research verifies stocks with higher retail investors’ shareholding proportion and unavailable for short show stronger ‘realized kurtosis puzzle’. In addition, the puzzle is particularly significant in high lottery preference periods while less apparent in low lottery preference times.     

Habit Formation in an Overlapping Generations Model with Borrowing Constraints

We introduce habit‐formation in the three‐period OLG borrowing‐constrained framework of Constantinides et al. (2002) by allowing the utility of the middle‐aged (old) to depend on consumption when young (middle‐aged). This specification enables us to separate the effect of the two habit parameters (middle‐aged and old) since each representative age‐group can face different levels of habit persistence. The two‐habit setup underlines some important issues with regards to savings and security returns which do not always conform to the standard findings in the literature. In addition, the model produces equity premium consistent with US data for relatively small levels of risk aversion.     

Resolving the innovation puzzle of latecomers: the case of Taiwan

In the currently rapidly changing business world, innovation has not only become the key to survival and success, but also the defining challenge of organisations. For latecomer firms, however, because of their inherent resource constraints, innovation has become a far more complex undertaking, similar to a multidimensional puzzle. Although there have been an increasing number of practitioner-based surveys, a discrepancy still remains between academia and industry concerning the role and importance of R&D in innovation. Therefore, this study carried out an industry–university–institution survey of Taiwan, based on a multidimensional framework of the innovation puzzle: human, R&D, flow and connection. The results reveal several interesting clues and provide a better understanding of the innovation puzzle for latecomers, and more importantly, resolves the puzzle that could help latecomers identify where new opportunities lie and what weaknesses they must strengthen.     

Selfishness, cooperation, the evolutionary point of view and its implications for economics

The assumed selfishness of market actors could be considered in the context of two perspectives: macroeconomic and microeconomic. The first concerns the market mechanism as the most effective from the social well-being or the wealth of a nation points of view. The latter is based on the premises of the nature of human beings. I have distinguished between two possible ways of understanding selfish forms of behaviour in the market: as rational economic behaviour i.e. the most effective from the gains and losses point of view (i.e. public interests in the works of A. Smith) or as selfish from the psychological point of view (this is mostly presented by J. S. Mill's theory). The first approach seems to be concerned with the creation of the most effective market mechanism from the State's point of view. In the context of historical processes over 400 years, cultural evolution “has been promoting” selfish behaviour; for example, it was widely presented in T. Hobbes' works and then for over 200 years, the theory of A. Smith has been supporting and moulding the institutional context of market and social behaviour. Thus, positive economics describes the market created by the ideas of a neo-classical paradigm, which is based on the normative premises of A. Smith and J. S. Mill. Moreover, the virtual market behaviour described by “effects” (f. e. Veblen's effect) and failures seems to be a manifestation of a discrepancy between market reality and the classical assumptions.The social evolution of human beings has been advantageous to the human species. Moreover, from the social point of view, pro-social behaviour is “natural” as well as desirable and it has been preferred by the cultural evolution. Competitiveness assumes that somebody has to lose, because someone gains. Cooperation looks for gains for all the players. The choice is political, and not imposed by selfishness.     

Adam Smith and the division of labour: is there a difference between organisation and market?

The paper claims that, in The Wealth of Nations, the divisionof labour refers simultaneously to two different things: a socialdivision of labour and an organisational division of labour.The central point is that the organisation of work (the organisationaldivision of labour) in the firm is the logical counterpart ofthe social division of labour, and that these reflect two inseparableaspects of the process of the division of labour. Smith is thusconcerned with organisations as well as with markets, each functioningaccording to the same principle. Hence, Smith does not believethat the organisational and the social divisions of labour arefundamentally different, although he does recognise some variationbetween them and describes different states of the divisionof labour within the firm, liberal and capitalist.     

Labour employed in production and labour commanded: a Ricardian conjecture

This paper explains the origin of some important ambiguitiesin the analysis of value and prices put forward by Smith inhis Wealth of Nations by considering the possibility that theyreflect a previous draft of the book where the quantity of labouremployed in production was indicated as the sole determinantof real price and exchange ratios. This conjecture is evidencedindirectly by the way in which Smith presented his own analysisat the end of Book I, Chapter IV; by some passages containedin Book I and Book II which suggest that the quantity of labouremployed in production should play a crucial role within theanalysis of exchangeable value; and by the important modificationsintroduced by Smith in Book I, Chapter VI, after the first editionof the Wealth of Nations was published.     

对经济学的"手"理论的述评

通过综合分析经济学理论关于"看不见的右手"(市场)、"看得见的左手"(政府)、"看得见的右手"(企业)和"看不见的左手"(权力及利益集团)的功能、缺陷及发挥各只"手"的功能所必需的约束条件,可以看出,要实现资源的优化配置、经济增长和社会和谐,各只"手"必须各司其职,发挥其长处、规避其缺陷,在其有效边界内运作而不是畸形发育,并处理好"四只手"之间的比例、结构和均衡关系。

Schools Out: Adam Smith and Pre-disciplinary International Political Economy

In this article, I argue that invocations of Adam Smith in international political economy (IPE) often reveal the influence therein of a disciplinary ontological disaggregation of economic and non-economic rationality, which I claim is obscured by the tendency to map its complex intellectual contours in terms of competing schools. I trace the origins of the disciplinary characterisation of Smith as the founder of IPE's liberal tradition to invocations of his thought by centrally important figures in the perceived Austrian, Chicago and German historical schools of economics, and reflect upon the significance to IPE of the reiteration of this portrayal by apparent members of its so-called American and British schools. I additionally contrast these interpretations to those put forward by scholars who seek to interpret IPE and Smith's contribution to it in pre-disciplinary terms, which I claim reflects a distinct ontology to that attributed to the British school of IPE with which their work is often associated. I therefore contend that reflection upon invocations of Smith's thought in IPE problematises the longstanding tendency to map its intellectual terrain in terms of competing schools, reveals that the disciplinary ontological consensus that informs this tendency impacts upon articulations of its core concerns and suggests that a pre-disciplinary approach offers an alternative lens through which such concerns might be more effectively framed.
