We investigate the short‐term relation between individual investor trading and stock returns on the Australian Securities Exchange. Stocks heavily bought by individual investors underperform stocks heavily sold over the subsequent three days, with respective returns on to a long–short portfolio of ?93, ?67 and ?12 basis points on days one, two and three. Individuals underperform in small and mid‐size stocks when they trade passively using limit orders waiting for the market price to move in their favour. Individuals underperform in large stocks when they trade aggressively using marketable orders. Foreign institutions gain from taking the opposite side of individual trades. We present an information asymmetry‐based explanation for the findings. 相似文献

The objective of this paper is to examine the role of consumer confidence on the relationship between two forms of wealth—housing and financial—and four categories of consumption expenditure, which include total consumption, service, durable goods and nondurable goods consumption. This paper uses U.S. quarterly data from 1978 to 2012 for its analysis. Applying the FMOLS estimation method, the results show that consumer confidence has a positive effect on the association between housing wealth and consumption expenditure, whereas its effect on the association between financial wealth and consumption expenditure is negative. The implications of these results are discussed. 相似文献

Experimental research on Group Decision Support Systems (GDSS) has generally focused on democratic groups whose members typically share the same objectives. In organizations, however, there are many situations where groups have a leader who has the power to override the group's recommendation, the objective of the leader may not be the same as the objective of each member, and not everyone may have the same information. This paper reports the results of an experiment in which the groups, having a designated leader, worked on a mixed-motive task. Within this context, we analyze group decision outcomes and processes for groups that use a face-to-face channel of cormnunication and those that utilize computer mediated communication. We compare performance of the leader and members with respect to an objective measure of performance, the efficient frontier. The results indicate that for this task groups using face-to-face channel outperform groups using computer mediated communication. 相似文献

While the existing literature focuses on the disclosure of social information mainly by large companies, this paper concentrates
on the disclosure of social information by small- and medium-sized companies (SME) listed on the Alternative Investment Market
(AIM) in the U.K. The paper investigates the prevalent view that SMEs are unlikely to report social information due to their
financial constraints and the perception that they have very little social conduct on which to report. Our overall evidence
illustrates that, contrary to this view, SMEs report social information regardless of their financial constraints, most likely
in the same manner as large companies do, because they realise the significance of social reporting in establishing and retaining
their corporate reputation. 相似文献

Objective: Few studies have examined the differences in self-reported driver behaviour between drivers of one nationality who live in their country of origin (domestic drivers) and those who live abroad (expatriate drivers). This study aimed to explore the differences in self-reported driver behaviour among domestic and expatriate Iranian drivers. In addition, we explore the factors associated with self-reported accident involvement including personal injuries in these groups. Methods: A web-based version of the Driver Behaviour Questionnaire (DBQ) measuring self-reported driver errors and violations was distributed to respondents by availability sampling in social networks and by bulk email services. About 1000 individuals living in all provinces in Iran were invited to participate in the survey. We also invited Iranians living in more than 20 countries. A total of 634 domestic Iranians and 135 expatriate Iranians responded to our enquiry. The measure of driving behaviour asked the respondents about violations and error conduct during the last two years on any kind of road. The sample of domestic and expatriate drivers did not differ significantly in gender, age, education and driving hours per day. Domestic drivers were more likely to have experienced an accident in their lifetime. Both samples were relatively young of age (Domestic M integer?=?28.53, SD?=?6.85; Expatriate M integer?=?29.21, SD?=?7.71). Results: The results suggested that emotional violations were more common among the drivers living in Iran. Emotional violations and driver errors were related to self-reported accident involvement among domestic drivers while ordinary rule violations were associated with such accidents in the expatriate group. Conclusions: Iranian expatriate drivers reported less emotional violations than domestic drivers. A potential reason is that road traffic infrastructure and regulation enforcement in high-income developed countries do not facilitate emotional violations. Implications for road traffic safety and methodological limitations of the study are discussed. 相似文献

Post-earthquake fire (PEF) is considered one of the most high risk and complicated problems affecting buildings in urban areas and can cause even more damage than the earthquake itself. However, most standards and codes ignore the implications of PEF and so buildings are not normally designed with PEF in mind. What is needed is for PEF factors to be routinely scrutinized and codified as part of the design process. A systematic application is presented as a means of mitigating the risk of PEF in urban buildings. This covers both existing buildings, in terms of retrofit solutions, and those yet to be designed, where a PEF factor is proposed. To ensure the mitigation strategy meets the defined criteria, a minimum time is defined – the safety guaranteed time target – where the safety of the inhabitants in a building is guaranteed. 相似文献

The effect of market uncertainty on a country’s currency, while widely recognized, is either omitted from mainstream models or addressed using low-frequency series, which are typically subject to aggregation bias and substantial lags. In this article, we propose a new mixed-data sampling (MIDAS) modelling framework that enables us to incorporate the asymmetric daily effects of market uncertainty in a conventional monthly error correction model. We achieve this by proxying market uncertainty via the value of a ‘safe haven’ asset (gold) that investors reallocate towards in the face of heightened market risk. We apply the model to the Iranian black-market exchange rate, using a mix of the daily price of gold (28 June 2010–19 August 2018) and monthly data (July 2010-July 2018) on relative prices. Our results indicate that purchasing power parity (PPP) holds despite the recent unprecedented depreciations in the Iranian currency arising from several rounds of international sanctions. We also find that increased uncertainty can lead to instantaneous and substantial depreciations, whereas stabilization back towards the PPP path is much more sluggish. 相似文献

This paper conducts an analysis of labour market dynamics in South Africa during the initial period of lockdown, from the end of March to the end of April 2020, using the first wave of the NIDS-CRAM (2020) survey. Within our sample of over 6,000 adults aged 18 to 59, we found that there was a very large decrease in employment. The fraction of the sample that was conventionally classified as employed decreased from 57% in February to 48% in April. If we further exclude temporarily absent workers, which we term “furloughed” employees, this fraction decreases further to 38%. Thus, about one out of every three employed people in our sample either lost their job or did not work and received no wages during April. This has extremely large implications for poverty and welfare. We further analyse the labour market by comparing across demographic groups as defined by race, by gender, by age groups, by geographic areas and by education levels. The over-arching finding from this analysis is that the job losses were not uniformly distributed amongst the different groups. In particular, groups who have always been more vulnerable – such as women, African/Blacks, youth and less educated groups – have been disproportionately negatively affected. 相似文献
