Smoking hot portfolios? Trading behavior,investment biases,and self-control failure

Self-control is a personality trait that explains undersaving and nonparticipation decisions. We show that self-control failure also affects trading behavior among individuals on capital markets. We use smoking as the most socially accepted example of self-control failure among 13,644 German brokerage clients and compare the trading behavior of 3,553 smokers and 10,091 nonsmokers. Smokers are associated with a higher portfolio turnover unexplained by financial sophistication or wealth effects. Self-control failure also exacerbates overconfidence, social contagion, sensation seeking, and attention grabbing. Overall, self-control failure is costly because it increases the gap between gross and net returns of smokers relative to nonsmokers.     

Social housing in France: A permanent and multifaceted challenge for public policies

This paper examines the dynamics of the overwhelmingly generous social housing in France that covers a wide spectrum of recipients. Being influenced by electoral power of rotating ruling parties and social ideals, policy formulations are often reflected by idealistic politics which tends to over-stretch the nation’s budget and restrict its scope in reaching its target groups. From the 1990s, fund availability has been further hit by economic globalization causing falling business profitability and high unemployment rates affecting notably ethnic minorities. Upcoming social crisis has been met with public response via a series of technical-led remedial acts to promote social integration in housing and by identifying social ills and polarization in sensitive and problematic urban quarters. New technical and financial measures in coping with the complexity and magnitude of social housing are expected to remain highly challenging in the French parliamentary politics.     

公司社会声望与高管薪酬:公共服务抑或职业声誉

本文基于“隐性—显性”契约激励研究范式,探讨公司社会声望对高管薪酬的影响以及作用机制。本文选取2009—2017年间的非金融A股上市公司为样本,研究发现,拥有较高社会声望的公司,其高管显性薪酬较低。具体而言,公共地位较高的国有企业、具有较高市场声誉的民营上市公司,其高管薪酬平均而言分别比其他上市公司低4.97%和6.30%。进一步地,我们发现公司声望对我国高管显性薪酬契约存在两种作用机制:一方面,公共地位较高的国有企业,可以为高管带来较高的社会声誉和社会认可,满足了“公共服务”类高管的社会声望偏好,从而降低了显性薪酬的支付水平;另一方面,市场声誉较高的民营企业,可以为高管带来较高的职业声誉和未来职业利益,符合“以商为荣”类高管的社会声望偏好,使高管愿意接受较低的显性薪酬。本文的结论为公司声望作为一种有价值的资源,可以对高管显性薪酬形成议价能力提供了重要证据,揭示了公司声望对高管显性契约激励的影响路径;同时,为国有企业高管薪酬契约设计以及激励机制提供了一定启示。     

Climate adaptation in ‘new world’ cultural landscapes: The case of Bay of Fundy agricultural dykelands (Nova Scotia,Canada)

North America has few cultural agricultural landscapes, and often commensurately poor governance arrangements for managing change in such settings. This research uses the Acadian dykelands of Nova Scotia, Canada, as an opportunity to explore the social and governance limits to coastal climate adaptation in ‘new world’ cultural agricultural landscapes, as well as inform local decision-making. Approximately half of Nova Scotia’s coastal wetlands were converted to dykeland in the 1600s, lowering local resilience to the increased frequency and storm severity anticipated with climate change. Today, dykelands protect a diversity of public and private interests, meanings and values, yet are controlled by the agricultural sector, which can no longer afford to maintain them all to 2050 climate projections. We report here on a representative online Q-methodology survey of 183 adult Nova Scotians in the spring of 2015. Respondents sorted 34 statements along a normal distribution about whether they prefer dykeland maintenance or wetland restoration, and under what governance arrangements. Four factors were derived: the dominant discourse was local, female and strongly pro-dykeland, indicating the likelihood for local resistance to dykeland removal on for cultural, recreational and farming reasons. The second factor was supportive of wetland restoration for reasons of efficiency, not wetland affinity, but characterized by those in positions of management power. The two minority viewpoints were less informed about dykelands, characteristic of outsiders, and concerned more with governance. More education is needed about the challenges facing dykelands, the benefits of coastal wetlands, and the management options, but this research shows proposals to change landscape should emphasize flood mitigation over cost-saving. Cultural values and status quo bias are clearly barriers to adaptation planning, even when discussing the removal of man-made structures. The factors were surprisingly polarized, suggesting the forced-normal distribution affects the space available to convey nuanced perspectives. Large p-set Q-method of this kind is likely most useful for characterizing the emergent discourses demographically, and understanding their prevalence; the same discourses had emerged within a much smaller pilot study.

Public sector enterprise disinvestment in India: Efficiency gains in a political context

India instituted a program of state enterprise disinvestment in 1991 as part of a sweeping reform initiative. This study analyses the effect of disinvestment on enterprise performance, conditioned on political context as characterized by the ideological leanings of the parties in power at state and central levels. Using stochastic frontier analysis, measures of firm efficiency are generated for 238 central public sector enterprises for the period 1991–1992 to 2010–2011. The relationship between efficiency so measured and disinvestment is then estimated using a two-stage instrumental variables approach to control for endogeneity between firm efficiency and selection for disinvestment. Initial disinvestment is associated with substantial efficiency gains, but subsequent disinvestment much less so and the proportion of shares disinvested only loosely so. This may be explained by the transformative effect of initial stock market listing on accountability and profit orientation that is not repeated with further rounds of disinvestment. The effect of disinvestment on performance is stronger if the enterprise is located in a state governed by a right leaning party or one that is ideologically aligned with the party in power at the centre.     

Competition in the stock market with asymmetric information

We build a game theoretical model to examine how the level of information advantage of insiders and the competition between insiders and sophisticated investors affect stock price movements and traders’ trading strategies and profits. We show that the competition between insiders and sophisticated investors can reduce the losses of less sophisticated investors, and thus alleviates the disadvantaged position of the less sophisticated investors. Further, traders’ profits are affected by the accuracy of insiders’ private information, and the number of days that insiders have obtained the information in advance. These findings show the importance of information transparency and the role of sophisticated investors in limiting insiders’ trading advantages and mitigating the expropriation of investors by insiders.     

Pure meat – Public perceptions of risk reduction strategies in meat production

Experience has shown that both the assessment and implementation of new technologies in food production are challenged by negative assessments of the technologies by the public. This article seeks to deepen our understanding of the concerns that may underlie negative attitudes to various kinds of risk reduction strategy in meat production, with the aim of distinguishing between forms of risk reduction in terms of their acceptability. The paper reports the result of a focus-group study. Six focus groups with Danish citizens (N: 5–9) were conducted during May 2006. The design of the groups took a bottom-up approach and included elements of meat quality, meat safety and risk reduction strategies. The study shows the dilemma risk reduction presents to members of the public. On the one hand, people want safe meat; on the other, the study showed that with the exception of hygiene practices, people generally have an aversion to risk reduction strategies. Some variation was found, however, in the rejection of the strategies. Thus, more acceptable strategies are characterised by a low degree of technological interference, and by being close to the consumer’s experience in everyday life and/or familiar to the participants’ picture of meat production. It is also important that the strategy does not alter the quality of the end-product (meat) in an unfavourable way. The implications of the results and the inherent dilemma for meat safety policy formation are discussed.     

The Managerial Lineages of Neoliberalism

Managerialism is often depicted as a key practice of neoliberalism yet relatively little has been written by scholars of neoliberalism about the actual relationship between managerialism and neoliberalism. Usually subsumed under a functional reading of neoliberalism, managerialism has too often been understood simply as a means for neoliberal ends (i.e. to promote market rule or competition). This paper challenges this perspective on the grounds that it conflates practices that stem from two different historical lineages. As we show, managerial governance not only has a very different history than neoliberal theory, but it also rests on different principles. Its development can be traced back to the US defence sector in the 1950s and the pivotal role of the RAND Corporation. On the basis of this historical perspective, we argue for the need to analyse managerialism on its own terms and make the case for considering the rise of managerial science as a paradigmatic shift in governance. In doing so, we show how managerial governance represented a radical rupture from previous management practices and show how it profoundly reshaped how we have come to understand governance.     

The effects of economic growth on income inequality in the US

The paper analyzes the relation between growth and income inequality in the US during the post-war years (1953–2008). We show that the income of the top income groups is more sensitive to growth, defined broadly as current growth and changes in expectations of future growth, compared to the income of the lower income groups. We provide evidence that this increased sensitivity arises for two reasons: (a) the top income groups receive a large portion of their income from wealth, which is more sensitive to growth than labor income and (b) the top income groups receive a large portion of their labor income in the form of pay-for-performance (equity compensation), which is also sensitive to growth. Consequently, we conclude that growth and income inequality are positively associated.
