Pairs trading is a popular dollar-neutral trading strategy. This article, using the components of the S&P 500 index, explores the performance of a pairs trading system based on various pairs selection methods. Whereas large empirical applications in the literature focus on the distance method, this article also deals with well-known statistical and econometric techniques such as stationarity and cointegration which make the trading system much more demanding from a computational point of view. Trades are initiated when stocks deviate from their equilibrium. Our results confirm, after controlling for risk and transaction costs, that the distance method generates insignificant excess returns. While a pairs selection following the stationarity criterion leads to a weak performance, this article reveals that cointegration provides a high, stable and robust return. 相似文献

This paper presents an experiment performed to test the properties of an innovative bargaining mechanism (called automated negotiation) used to resolve disputes arising from Internet-based transactions. The main result shows that the settlement rule tends to chill bargaining as it creates incentives for individuals to misrepresent their true valuations, which implies that automated negotiation is not able to promote agreements. However, this perverse effect depends strongly on the conflict situation. When the threat that a disagreement occurs is more credible, the strategic effect is reduced since defendants are more interested in maximizing the efficiency of a settlement than their own expected profit. The implications of these results are then used to discuss the potential role of public regulation and reputation mechanisms in Cyberspace. 相似文献

Using income tax administrative data for Australia, we examine levels and trends in the persistence in top-income group membership, focusing on the top 1 percent. Top-income persistence increased markedly between 1991 and 2018, with most of the increase occurring in the mid-2000s and early 2010s. In the mid- to late-2010s, Australian top-income persistence rates were near the top of the range of tax-data estimates for other countries. We decompose the increase into factors associated with (i) changes in the composition of the top-income group and (ii) increases in persistence rates for specific population subgroups. We find that the rise in top-income persistence is accounted for by changes in subgroup persistence rates, notably for individuals aged 35–64, and especially those aged 55–64. We suggest that these effects are partially related to increases in the effective retirement age over the relevant period. 相似文献

Although the productivity and survival of small and medium-sized enterprises (SMEs) may be enhanced if they adopt human resource management (HRM) practices, there is a far greater degree of informality in employment practices in SMEs than in larger workplaces. The aim of this paper is to assess the extent to which a range of factors both internal and external to the workplace predict the extent to which HRM practices have been adopted in SMEs. Using data from the 1998 Workplace Employee Relations Survey, the analysis reveals that differences in workforce skill-mix, unionization and the customer base are important influences, with the first of these influences being particularly strong. As such, we suggest SMEs may lack the capability to develop HRM practices, but they are more likely to adopt such practices if they employ highly skilled employees and are networked to other organizations 相似文献

Exploiting the award process, we implement a regression discontinuity design to estimate the effect of winning France's main literary prize, the Goncourt. It increases sales, especially for books that sold fewer copies before the announcement, the number of reviews on Amazon, and the probability of them being negative. The effect is partly driven by an increase in word of mouth. Those findings are consistent with a model where the prize provides information on the existence of a book and acts as a quality signal and a coordination device but prompts consumers to read books that are far from their tastes. 相似文献

Knowledge flows and the geography of networks: A strategic model of small world formation 总被引:3,自引:0,他引:3
This paper aims to demonstrate that the strategic approach to link formation can generate networks that share some of the main structural properties of most real social networks. For this purpose, we introduce a spatialized variation of the Connections model [Jackson, M.O., Wolinsky, A., 1996. A strategic model of social and economic networks. Journal of Economic Theory 71, 44–74] to describe the strategic formation of links by agents who balance the benefits of forming links resulting from imperfect knowledge flows against their costs, which increase with geographic distance. We show, for intermediate levels of knowledge transferability, clustering occurs in geographical space and a few agents sustain distant connections. Such networks exhibit the small world property (high clustering and short average relational distances). When the costs of link formation are normally distributed across agents, asymmetric degree distributions are also obtained. 相似文献

Two of the main puzzles in international economics are the consumption and the portfolio home biases. We solve for international equity portfolios in a two-country/two-good stochastic equilibrium model with trade costs in goods markets. We show that introducing trade costs, as suggested by Obstfeld and Rogoff [Obstfeld, M., Rogoff, K., 2000a. The Six Major Puzzles in International Macroeconomics: Is There a Common Cause? NBER Macroeconomics Annual, 15], is not sufficient to explain these two puzzles simultaneously. On the contrary, we find that trade costs create a foreign bias in portfolios for reasonable parameter values. This result is robust to the addition of non-tradable goods for standard calibrations of the preferences. 相似文献
