Testing weak form efficiency on the Toronto Stock Exchange

In order to test for weak form efficiency in the market a vast pool of individual stocks must be analyzed rather than a stock market index. In this paper, a model-based bootstrap is used to generate a series of simulated trials and a modified chart pattern recognition algorithm is applied to all stocks listed on the Toronto Stock Exchange (TSX). The number of patterns detected in the original price series is compared with the number of patterns found in the simulated series. By simulating the price path specific time dependencies present in real data are eliminated, making price changes purely random. Patterns, if consistently identified, carry information which adds value to the investment process, however, this informativeness does not guarantee profitability. Conclusions are drawn on the relative efficiency of some sectors of the economy. Although the null hypothesis of weak form efficiency on the TSX cannot be rejected, some sectors of the Canadian economy appear to be less efficient than others. In addition, pattern frequencies appear to be negatively dependent on the two moments of return distributions, variance and kurtosis.     

Classification of micro,small and medium enterprises (M-SME) based on their available levels of knowledge

This paper proposes a novel and practical method of classifying micro, small and medium enterprises (M-SME) based on their available levels of knowledge. This classification considers that the specific problems that dominate a company’s operations are related to the level of knowledge available. Therefore, identifying the dominant problem groups facing the company can enable an estimate of the level of knowledge available in the enterprise.Data from 2698 Mexican M-SMEs are used to identify operational problems. The main problem groups are obtained through a cluster analysis. The proposed classification consists of three levels of knowledge based on the interpretation of the dominant problem groups in each enterprise. Each of the 2698 Mexican M-SME are classified by a discriminant analysis.Nearly half of the M-SME are classified as having a lower level of available knowledge, and only 10% are classified with the highest level. No difference is observed between the size of the company and the level of available knowledge. This means that growth in the number of employees and sales of M-SMEs is not necessarily accompanied by an accumulation of knowledge that companies can use to improve their operations.

Relationship regarding the demand for labor between domestic temporary and foreign workers: Korean case

With the progress of globalization, South Korea, one of the emerging industrial countries, has recently witnessed a sharp increase in the number of enterprises that employ foreigners. However, there are only a limited number of studies on the influence that such an increase has had on the labor market in the Republic of Korea. Thus, using ‘Workplace Panel Survey’ data surveyed by the Korea Labor Institute (KLI), this paper examines the relationship concerning the labor demand of an establishment between domestic temporary and foreign workers. Analysis using a bivariate Tobit model shows that a typical Korean firm attempts to employ domestic temporary and foreign workers simultaneously. Further, the empirical analysis found that any establishment that is relatively newly established and has difficulty in recruiting domestic workers hires foreign workers, but there is no evidence that establishments hire foreign workers rather than domestic temporary workers to save on the production cost.     

State wage-payment laws, the Pension Protection Act of 2006, and 401(k) saving behavior

I show empirically that state wage-payment laws, which forbid deductions from wages and salaries without the written permission of the employee, constituted a binding constraint on firms’ choices to adopt automatic enrollment in 401(k) plans prior to 2006.     

Separating the Hawks from the Doves: Evidence from continuous time laboratory games

Human players in our laboratory experiment received flow payoffs over 120 seconds each period from a standard Hawk–Dove bimatrix game played in continuous time. Play converged closely to the symmetric mixed Nash equilibrium under a one-population matching protocol. When the same players were matched in a two-population protocol with the same bimatrix, they showed clear movement towards an asymmetric (and very inequitable) pure Nash equilibrium of the game. These findings support distinctive predictions of evolutionary game theory.     

乡村旅游主题下休闲农业发展研究——以山西省100个3 A级乡村旅游示范村为例

以山西省首批100个3A级乡村旅游示范村为研究对象,运用最近邻指数、地理集中指数、核密度分析等空间分析方法及建立乡村旅游资源分类体系,对其空间结构和分类特征进行测度。结果表明:样本点空间分布为集聚型,分布高密度区域主要在山西省中东部、东南部和南部,北部和西部分布密度较低。山西省休闲旅游资源丰富,为乡村旅游提供了大量资源,五种乡村发展类型中,特色文化型村庄占比最大,休闲农庄和城郊发展型村庄相对较少。最后根据研究结果提出相关建议。     

论触电人身损害赔偿的法律适用

从不同的角度,触电人身损害赔偿案件有不同分类。不同类型的案件,法律适用原则不同。审理触电人身损害赔偿案件应认真梳理案件的法律关系,采用正确的侵权归责原则,公正、合法地追究当事人的责任。
