我国地区产业结构调整及其效益分析

改革开放以来,我国四大地带产业结构的变动趋势大致相同,但东部各产业的劳动生产率和对经济增长的促进作用要明显优于中、西部和东北.目前四大地带产业排序已由二一三转变为二三一,接下来应促使第一产业的发展与农产品加工工业的发展相互适应,才能使区域的经济增长达到最佳效益.同时,鉴于各地带二、三产业对经济增长促进作用的大小同各产业从业人员的劳动生产率成正比,地区产业结构的调整还应注意劳动生产率的提高.     

劳动关系作为法律关系:兼论劳动法学研究的范式转换

劳动关系和劳动法律关系区分的理论更多是法外视角研究劳动关系问题的结果。法律调整社会关系或劳动关系并非是指存在先在的供法律调整的社会关系,而是指法律通过规范人的行为在当事人之间产生法律关系,该法律关系是社会关系的特殊形式;法律关系产生的过程不是寻找社会关系的过程,而是判断法律规范规定的构成要件是否具备的过程。法律调整劳动关系因此是指出现法律规范的构成要件时在当事人之间产生以一方提供依附性劳动、另一方支付报酬为主要义务的权利义务关系,也即法律意义上的劳动关系。从上述劳动关系的逻辑出发,则事实劳动关系概念需要正本清源,集体劳动关系非法律意义的劳动关系,劳动法律关系、社会劳动关系、个别劳动关系等概念无存在必要。劳动法学研究应实现从法外视角向法教义学研究并重的转换。我国劳动法的规则体系和理论体系应围绕劳动关系展开。     

Network based evidence of the financial impact of Covid-19 pandemic

How much the largest worldwide companies, belonging to different sectors of the economy, are suffering from the pandemic? Are economic relations among them changing? In this paper, we address such issues by analyzing the top 50 S&P companies by means of market and textual data. Our work proposes a network analysis model that combines such two types of information to highlight the connections among companies with the purpose of investigating the relationships before and during the pandemic crisis. In doing so, we leverage a large amount of textual data through the employment of a sentiment score which is coupled with standard market data. Our results show that the COVID-19 pandemic has largely affected the US productive system, however differently sector by sector and with more impact during the second wave compared to the first.     

Human–capital investment and the wage gap

Summary. According to empirical studies, the wage differential by skills evolved non–monotonically in the past decades although the relative supply of skilled labor steadily increased. The present paper provides a theoretical explanation for this finding. In our setting, technological change intertemporally alters the human–capital investment incentives of heterogeneous individuals. As a consequence of changing incentives, the time path of the relative wage is U–shaped while there is a rise in the share of skilled workers.

Double Moral Hazard,Monitoring, and the Nature of Contracts

generalized double-sided moral-hazard model, with risk-averse parties who mutually monitor each other (to get a reasonable idea of outcome/effort). The model considers trade-off between monitoring costs and moral hazard costs, which are endogenously determined by the extent of monitoring. Using this model, we formally prove a generalized version of Coase's conjecture – that the optimal contract minimizes the agency and risk costs. We then show how varying assumptions about the feasibility or cost of monitoring of the outcome or the worker's effort lead to different contracts being optimal. The analysis is then used to explain the nature of contracts observed in practice under many different situations. We will give an explanation as to why industrial workers typically work under wage contracts, while share contracts are common in agriculture and will explain why profit sharing is more common for senior managers than for the production workers.

论缓停建工程中优先权的冲突与顺位确定

由于缓停建工程所涉及的法律权利的复合性与多重性,债权人在实现自己的债权时势必会与他人的民事权利产生冲突,须确立一定的规则来协调各种权利冲突,使处于优位的特定债权人的利益得到保障。在确立解决优先权之间冲突原则的基础上,尚须对各项权利安排合理的顺位,以为法院处理此类问题提供一条切实可行的思路。     

遗传算法及其在客户关系管理中的应用研究

遗传算法是一种宏观意义下的仿生优化算法，它模拟生物在自然环境中的遗传和进化过程而形成的一种自适应全局优化概率搜索算法。这种算法可以用于对海量的客户信息进行搜索，提取对决策有用的信息，让企业在激烈的市场竞争中处于有利地位，最终达到最高利润。本文还通过一个简单的实例研究将该算法应用在客户关系管理中。     

Regulating an externality-generating public utility: A multi-dimensional screening approach

In this paper, I present a monopoly screening model in which a firm holds private information on fixed abatement costs. Because of the nature of the optimal contracts, bunching is never optimal even with ‘n’ distinct types. A characterization of full and limited information solutions is offered and it is shown that the design standards alone determine the value of an information rent. The variable charge is completely free of any marginal information costs. This allows the variable charge to track marginal damages and thereby ensures that marginal social costs are covered. A fixed charge implements the optimal solution.     

浅议我国商业银行中间业务的法律风险与防范对策

商业银行中间业务的开展对促进商业银行提高经营效益、降低银行风险，以及实现可持续发展等方面发挥了重要作用。然而现阶段我国商业银行发展中间业务时面临诸多法律风险，如立法上的缺陷、法律的滞后性等。因而，应积极制定有关法律、法规，适度监管，为商业银行中间业务的开展营造良好的法律环境。
