On the economic and social benefits of direct selling

The labor market has long included individuals seeking nonemployee, alternative work arrangements. Now, alternative work arrangements such as freelancing, independent contracting, and temporary contracts have entered the lexicon through the following terminology: the gig economy, the sharing economy, the YouEconomy, agile workforce, and contingent workers. There are currently an estimated 18.6 million independent contractors engaged in direct selling. This article reports the first attempt to empirically investigate and document both the economic and social impacts of direct selling in the U.S. Our findings suggest that direct selling has a consequential impact on the U.S. economy and that the direct selling experience fosters a variety of skills that benefit professional activities as well as the personal lives of millions of independent workers.     

中国银行业的外国直接投资:意义及挑战

上世纪90年代,全世界新兴市场国家的银行业出现了外国直接投资迅速增加的现象,这些外国直接投资相应给这些国家的银行体系带来了深远的影响。作为世界银行业全球化发展的组成部分,从2003年开始,中国银行业证明了一个史无前例的新现象—大量的FDI涌入中国银行业,购买股份抢占中国银行业市场。本文试图描述银行FDI在中国的现状,并探索背后的主要原因,包括监管规则的改变、经济的稳健增长、银行业的发展和持续的非金融FDI。银行在公司治理、风险管理、内部控制和人力资源管理等方面出现初步但富有帮助的变化。整个银行体系也发生了变化,包括行业形象得到改善、信用文化得到培养、透明度得到加强、创新得到发展、效率得到提高。然而,对于整个银行体系和经济的有意义的影响目前还没有出现。尽管通过吸引国外有经验的合格战略投资者引进了国际先进的管理惯例,对于中国的银行来说,仍然需要很长时间来全面改革自己的信贷文化和不清晰透明的行为。而且,随着中国的全面开放,前面将会有很多艰巨的挑战,因此,作为一个新兴经济体,一定要有远大视野,全面理解银行业中FDI的长期重要角色,创造外国战略合作伙伴发挥其积极作用的必要条件,督促其提供服务的步骤,以及中国银行系统在全球银行价值链中的正确地位。     

国际对冲基金监管制度比较研究与启示

对冲基金近年发展迅猛,各国根据本国国情初步建立了监管制度。本文认为应从改进治理结构、强化自律监管,加强市场约束、提高透明度等方面,沿运营流程和主要运营当事人两条线索完善对冲基金现有监管法律制度。在金融市场全面开放背景下,我国应在放开私募管制基础上根据市场和金融产品发展进程推进对冲基金逐步合法化。     

The futures of offshoring FDI in high-tech sectors

This paper examines what is still a relatively new phenomenon in the literature, the outsourcing/offshoring of high-technology manufacturing and services. This has become a concern for both policy makers and academics for two reasons. Firstly, policy makers have become concerned that the offshoring of high-technology sectors in the West will follow the more labour intensive sectors, and move to lower cost locations. Secondly, international business theory has tended to view low costs, and high levels of indigenous technological development as being the two main drivers of location advantage in the attraction of FDI. We show that this may not be the case for offshored high-technology manufacturing or services.     

An analysis of the reasons for the asymmetries surrounding earnings benchmarks

Several studies report an asymmetry in the distribution of earnings around specified benchmarks. However, doubt has arisen over whether the observed ‘kink’ in the distribution of earnings is solely caused by earnings management. We use a ratio analysis approach to examine a range of specific accruals for evidence of earnings management. We find little evidence that firms immediately above the benchmark have abnormal receivables, inventories or provisions. However, they do increase cash‐from‐customers and reduce inventory. Thus, our results support the recent research that suggests that firms engage in real actions to meet earnings benchmarks.

Introducing a preliminary consists selection in the locomotive assignment problem

The Locomotive Assignment Problem (LAP) is a class of planning and scheduling problems solved by assigning a fleet of locomotives to a network of trains. In the planning versions of the LAP, the type of consist (a group of linked locomotives) assigned to each train in a given schedule is determined. We introduce an optimization model (called consists selection) that precedes the planning LAP solution and determines the set of consist types. This selection leads to solutions that are characterized by potential savings in terms of overall fueling cost and are easier to handle in the routing phase.
