We use two extremely liquid S&P 500 ETFs to analyze the prevailing trading conditions when mispricing allowing arbitrage opportunities is created. While these ETFs are not perfect substitutes, our correlation and error correction results suggest investors view them as close substitutes. Spreads increase just before arbitrage opportunities, consistent with a decrease in liquidity. Order imbalance increases as markets become more one-sided and spread changes become more volatile which suggests an increase in liquidity risk. The price deviations are followed by a tendency to quickly correct back towards parity. 相似文献
AbstractThe increase in food-related diseases in society has led to a variety of public policy and private sector initiatives, such as the use of nutritional labels. Although nutritional labels have been shown to be broadly effective in terms of informing food choice, their influence is moderated by a variety of factors, such as how information is conveyed and processed by consumers. Recent advances in technology might overcome these limitations. Using a choice experiment, this paper examines consumer preferences for alternative technological devices that may aid consumer processing of nutritional information on food packaging. The results show which attributes of the technology consumers prefer, and identifies three distinct segments of consumers (‘information hungry innovators’, ‘active label readers’, and ‘onlookers’), and differences between them in relation to their preferences, demographics, and psychographic characteristics. The identification of segments is a novel aspect of this research, and highlights the importance of finding more customised solutions to the communication of nutritional information – an issue to which technology can contribute. 相似文献
ABSTRACTThis report investigates whether deregulation of the Australian wheat export market induced a structural change in the price data generation process. We analyze the unit root properties of Western Australian wheat price series by testing for the possibility of single and double structural breaks. Daily spot prices for the period of May 20, 2003, to September 14, 2010 are used. We find the wheat price series has a unit root with two structural breaks but neither breaks coincides with the time when the Wheat Export Marketing Act 2008 came into effect on July 1, 2008. The implication of our results is that deregulation was not the main cause of structural breaks in the price series in the sample period. 相似文献
We investigate the welfare effects of inflation in economies with search frictions and menu costs. We first analyze an economy where there is no transaction demand for money balances: Money is a mere unit of account. We determine a condition under which strictly positive inflation is desirable. We relate this condition to a standard efficiency condition for search economies. Second, we consider a related economy in which there is a transaction role for money. In the absence of menu costs, the Friedman rule is optimal. In the presence of menu costs, the optimal inflation rate is negative for our numerical examples provided menu costs are small. A deviation from the Friedman rule can be optimal depending on the extent of the search externalities. 相似文献
This paper provides a systematic analysis of fiscal decentralization on the quality of government by studying jointly its effects on electoral discipline and selection, in a setting where, realistically, voters only have limited information about fiscal policy in other jurisdictions, ruling out yardstick competition. Fiscal centralization reduces the extent of electoral discipline, as a corrupt (rent-seeking) incumbent can target good behavior only at a “minimum winning coalition” of regions (selective rent-diversion) in order to retain office, but thus makes it more profitable for bad incumbents to pool with good ones, thus increasing the probability of electoral discipline occurring at all. Voters tend to prefer centralization when politicians are low quality i.e. more likely to be corruptible. Centralization with uniform taxes can dominate both unconstrained centralization and decentralization, explaining why uniform taxes are so widely observed. 相似文献
This article assesses the quality of Integrative Social Contracts Theory (ISCT) as a social contract argument. For this purpose,
it embarks on a comparative analysis of the use of the social contract model as a theory of political authority and as a theory
of social justice. Building on this comparison, it then develops four criteria for any future contractarian theory of business
ethics (CBE). To apply the social contract model properly to the domain of business ethics, it should be: (1) self-disciplined,
i.e., not aspire results beyond what the contract model can realistically establish; (2) argumentative, i.e., it should seek
to provide principles that are demonstrative results of the contractarian method; (3) task-directed, i.e., it should be clear
what the social contract thought-experiment is intended to model; and (4) domain-specific, i.e., the contractarian choice
situation should be tailored to the defining problems of business ethics. 相似文献
This paper examines the relation between incentive pay, monitoring, and regulatory requirements in banks. Using a one-period model with asymmetrical information between the bank owner and the top management team, as well as within the team itself, we show that (1) incentive pay increases the mutual-monitoring activity among top executives; (2) senior executives, especially the CEO, collect more incentive pay than their subordinates; and (3) bank regulations, such as capital adequacy (CAD) requirements, reduce the absolute amount of incentive pay granted to executives. 相似文献
ABSTRACTDrawing upon 50 years as an academic economist, this lecture to alumni of SOAS’s Department of Economics reflects upon the continual ‘post-truth’ aspects of mainstream economics, ranging over its substantive, if shifting, content, and its treatment of methodology and interdisciplinarity. It draws upon a wide range of theory, empirical analysis, policy and anecdote to highlight both the need for alternatives and the continuing, even increased, failure of the mainstream to engage with criticism and alternatives. 相似文献
In this paper, we investigate IPO first-day returns in French market. Our focus is to assess the relationship between equity risk, corporate leverage and IPO initial returns. Based on data of 254 French IPOs, traded on Euronext/Alternext markets over the period 2006 and 2016, we find that estimated beta and idiosyncratic volatility are strongly and negatively related to book and market net gearing ratios. We also find that the interaction terms between equity risk measures and corporate leverage ratios are inversely related to IPO first-day returns. In addition, we highlight that industry and macroeconomic environment variables are significant predictors of equity initial returns. Robustness check of our findings indicates less relevant results for corporate leverage when it is estimated as independent variable.
