The making of a petrol station and the “on-the-move consumer”: Classification devices and the shaping of markets

This paper addresses the issue of classification devices and their role in shaping markets. We depart from the notion that markets are shaped by multiple calculative agencies and examine how particular forms of calculation are made viable. Classification devices are the infrastructure that makes calculation possible and sustains particular economic orders. We illustrate these notions with an empirical, longitudinal study of a fuel retail company and its initiative to re-classify its network of petrol stations across Europe. Our study focuses on the extensive and protracted negotiations over what constituted relevant categories and the multiple perspectives involved in defining petrol station types. We illustrate how a store typology plays an important role in making assemblages of ideas (e.g. consumer-on-the-go), objects (e.g. store planograms), and managerial roles (e.g. category managers) coalesce around particular constellations of practices which impact upon the outline of markets.     

Do Japanese Work Shorter Hours than before? Measuring trends in market work and leisure using 1976–2006 Japanese time-use survey

Using Japanese time-use data from the Survey on Time Use and Leisure Activities (STULA), this paper measures trends in average hours worked (market work) and leisure for Japanese over the past three decades. OECD reports at least a 15% decline in market work for Japan since the 1970s. However, holding demographic changes constant, we found that market work per week increased from the 1970s until mid-1980s, and has been relatively stable for the last two decades for both male and female full-time workers. Furthermore, although the market work per week remained relatively constant since the mid-1980s, we found a significant change in the allocation of time to market work within the week during the period. Specifically, when dividing samples into weekdays (Monday–Friday) and weekends (Saturday and Sunday), average hours spent for market work per weekday among full-time males increased by 0.4 h since the mid-1980s, whereas a significant decline in market work on Saturday was observed. This suggests that people shifted their work time from Saturday to weekdays in response to the reduced work week introduced by the amendment of the Labor Standards Act at the end of 1980s. In the meantime, commuting time and home production had decreased by 3 h since the mid-1980s for full-time female workers, indicating that the average hours of leisure had increased for females even though market work remained the same. Interestingly, however, hours for sleep declined consistently over the last three decades, resulting in a 3–4 h reduction per week for both male and female workers. Lastly, a comparison of Japanese and US time-use data suggests that Japanese work much longer than their American counterparts. On average, Japanese males work 10 h longer per week, and Japanese females 7 h longer, than Americans, even after adjusting for demographic differences between the countries.     

基于交易量持续期的流动性研究

本文充分利用我国限价指令驱动市场分笔数据所包含的信息。在交易量持续期的基础上,提出一个符合限价指令驱动市场特征的流动性指标,并从市场微观结构理论出发．选取了非对称信息的若干代理变量,分析非对称信息对市场流动性的影响程度。对万科A、B股的实证结果发现：（1）交易量持续期拥有信息含量,看涨行情会导致交易强度增大,看跌行情则导致较长的持续期。这反映了卖空限制的作用和投资者的追涨行为。（2）非对称信息是影响流动性水平的重要因素,投资者看法差异严重、价格剧烈波动以及长的交易量持续期导致市场流动性降低。     

The holiday and Yom Kippur War sentiment effects: the Tel Aviv Stock Exchange (TASE)

Several empirical studies reveal that holidays generally create positive sentiment in the stock market, whereas negative events, such as wars or disasters, are accompanied by negative sentiment. However, what happens if a negative event occurs on a holiday? In such a case, we expect two conflicting sentiment effects, which may cancel one another out or, alternatively, one effect may dominate the other. The stock market in Israel provides a unique laboratory in which to test these two conflicting effects, as Israel faced a horrible war on the Yom Kippur holiday in 1973—a war whose influence is still strongly felt today. Indeed, we find two robust effects: A strong and significant positive holiday sentiment effect; and a negative war sentiment effect, which dominates the positive holiday effect. These results, which show how sentiment effects are created, are general and can easily be applied to other events and other markets when conflicting sentiment effects occur.     

投资者适当性制度构建:国际经验与本土选择

投资者适当性制度对投资者保护、完善券商内部治理、减少系统性金融风险、促进金融创新等方面都有重要作用。然而,实践中还存在着投资者分类保护与现实脱节、投资者权利救济难以实现等现实问题,投资者适当性制度仍具有讨论价值。投资者适当性制度起源于美国,美国证监会以"买者有责"为核心,形成了以代理理论、特殊情况理论和信义义务理论为内容的适当性理论基础,而我国投资者适当性的理论基础应当是在信赖利益理论的基础上对美国理论基础的延伸与发展。国外的投资者适当性制度在客户适当性、投资者教育、投资者权利救济方面形成了较为完整的规则体系。我国投资者适当性制度在上述方面虽有一定发展,但在实践层面仍存在一定的问题。我国投资者适当性制度今后的发展重点应更多放在立法模式选择、投资者分类制度、投资者教育机制、投资者权利救济方面。     

New development: Are social impact bonds (SIBs) viable in Italy? A new roadmap

This paper presents a roadmap to support the development of social impact bonds (SIBs) in Italy. Current barriers and opportunities are explained. SIBs should be piloted in areas where the cultural, ideological, technical and governance barriers are low. Accurate measurement systems will be necessary and an effective governance structure needs to be agreed. With careful piloting and follow-up, the SIB model could be a solution to welfare and public service funding in Italy.     

Maintaining market principles: Government auditors,PPP equity sales and hegemony

The UK's government auditors, the National Audit Office (NAO), play a central role in the accountability relations surrounding government expenditure. Commonly portrayed as being independent, they carry out performance audits assessing value for money. To date, the emerging market for PPP equity transactions has attracted little attention. This paper explores that emerging market through a Gramscian framework utilising the concepts of ‘common sense’ and ‘good sense’, focusing on a dialogical analysis of a NAO report on the topic.In the process, the paper contributes to the debate about the nature and role of government auditors.     

Structural changes in covenants through the adoption of IFRS in Brazil

This study examines changes in the structure of covenants in debt agreements of companies issuing debentures during the adoption of International Financial Reporting Standards (IFRS) in Brazil. We investigate debt contracts of public and private companies that issued debentures before and after IFRS adoption in Brazil, between the years 2006–2008 and 2011–2014. We develop a database with all covenants from 126 contracts via hand-collected data, with 78 contracts from before IFRS adoption and 48 contracts afterward. We find high increases in covenants after adoption. However, this growth is observed only for restrictive security and non-accounting covenants, excluding clauses with accounting multiples. Our results show that IFRS adoption in Brazil shifted incentives and, as a result, shaped a new structure of debt contracts. Our findings complement and expand previous studies and can be useful to academics, regulators and practitioners by showing that the incentives to use accounting figures and ratios shifted in the credit market after IFRS adoption.     

A lattice-based model to evaluate variable annuities with guaranteed minimum withdrawal benefits under a regime-switching model

We consider the problem of evaluating variable annuities with a guaranteed minimum withdrawal benefit under a regime-switching model. We propose a trinomial lattice model to approximate the evolution of the investment fund value and the policy value at inception is computed through a backward induction scheme. Finally, the insurance fee is computed as the solution of the equation that makes the contract actuarially fair. Numerical results are reported to illustrate the consistency of the proposed model.     

Feedback trading in stock index futures: Evidence from South Africa

This study tests whether investors and speculators in stock index futures contracts on the South African stock market use feedback trading strategies. Feedback trading can be destabilizing and impede on the risk mitigation and price discovery functions of futures contracts. Using the Sentana and Wadhwani (1992) model, and accounting for the global financial crisis, we find no evidence of feedback trading in the Top40 futures index or the Top40 mini futures index contracts. Our findings have important implications for investors who wish to use index futures to mitigate risk or exploit arbitrage opportunities and regulators concerned about the destabilizing effects of futures trading.
