商业银行流动性过剩问题的再认识

最近,学术界对商业银行流动性问题议论颇多,议论的焦点是银行的流动性过剩及由此引发的种种后果.本文基于既往研究中值得深思的四个问题,从商业银行超额储备构成出发对流动性过剩的内涵、判断标准及影响因素进行界定,以商业银行保持流动性成因的微观视角管窥我国商业银行流动性过剩问题.在此基础上,本文认为商业银行流动性过剩问题的解决与资本市场的发展并无必然的直接联系,并针对流动性过剩问题的不同形成原因提出了相应的几点看法.     

我国煤炭产业过度竞争原因及对策

目前我国煤炭产业低级低效、高度分散的竞争型市场结构,即理论上称的“原子型”结构,是造成我国煤炭产业过度竞争的原因。煤炭过度竞争使我国煤炭资源浪费、资源价格扭曲、部分国有企业亏损严重和煤炭行业效益持续低下,解决我国煤炭过度竞争必须通过提高产业进入门槛,降低产业退出门槛,提高煤炭产业的集中度,实施大型煤炭企业集团战略并对此给予必要的政策扶持。     

从汇率制度视角看我国商业银行的流动性过剩

从汇率制度角度透视我国当前的商业银行流动性过剩现象,目的在于为经济金融的进一步开放提供理论依据和决策参考。本文通过对“三元悖论”理论的解读和1998～2006年各季度数据的实证检验,揭示了我国商业银行流动性过剩与汇率制度之间存在密切相关性,即在我国现行的汇率制度下,外汇储备的不断增加直接导致了商业银行存差的扩大,造成金融系统乃至整个社会的流动性过剩。基于上述研究,作者提出了如下相关建议:完善我国汇率形成的市场机制,培育相对均衡汇率;深化我国外汇管理体制改革,有序开放资本市场;汇率制度改革要与其他政策改革协调配合。     

多重委托代理下医生最优激励模型设计探究

"过度医疗"即指超过疾病实际需求的诊断和治疗的行为。医疗服务的特殊性,使患者、医生、监督方之间存在信息不对称和多重委托代理关系。鉴于此,从政府的第三方监督职能出发,将政府和患者作为共同委托人,避免政府与医院之间道德风险的发生,构建医生作为代理人的最优激励模型,并得出相关结论与启示。     

FINANCE,DISTRIBUTION AND THE ECONOMIC OBJECTIVE OF FINANCIAL COOPERATIVE INSTITUTIONS

This paper proposes a model where the structure rather than the size of the financial sector explains its influence on income distribution. Because of information asymmetries, a financial sector dominated solely by profit‐maximizing financial intermediaries will increase income and wealth inequality as it gives preferential access to credit for high‐income agents, whereas a diversified inclusive financial sector with alternative models of finance, like cooperatives, will reduce the inequality gap. No full convergence in income distribution can be realized through finance only and there is still a need for redistribution policies. Accordingly, an objective function for cooperative financial institutions should define a desired pricing behaviour that can increase the income of members at a rate higher than the average growth rate of the economy.     

Financialization of Housing in Brazil: New Frontiers

The financialization of housing has been increasingly identified as an important driver of social and economic change in contemporary capitalism. Focusing on the Brazilian context, this article considers the extent to which recent changes in housing regulations, policies and markets confirm or challenge narratives about the financialization of housing in the international academic debate. I argue that while many of the trends stressed in the literature are apparent, more extreme processes of financialization within the Brazilian housing sector remain limited––not only because of institutional and regulatory constraints, path dependence or political resistance, but also because of fundamental structural conditions of Brazil's position as a peripheral economy. Three different but mutually reinforcing processes are scrutinized in order to evaluate the financialization of housing and its limits in Brazil: the re‐regulation of the real estate financial sector initiated in the 1990s; the changing funding patterns among real estate companies since the mid‐2000s; and the increasing commodification of housing induced by a large‐scale and heavily subsidized housing program launched in 2009.     

The Variegated Financialization of Housing

There is a small but growing literature on the financialization of housing that demonstrates how housing is a central aspect of financialization. Despite the varied analyses of the financialization of housing and the importance of housing to financialization, the relations between housing and financialization remain under‐researched and under‐theorized. The financialization of housing is not really a specific form of financialization, transcending as it does a number of different forms of financialization. Housing systems, in particular, vary widely across the globe, which implies that housing financialization will be inherently variegated, path‐dependent and uneven. In this introduction to the symposium, I will discuss how the articles to follow contribute to the literature on the financialization of housing. Housing has entered a post‐Fordist, neoliberal and financialized regime. Increasingly, both mortgaged homeownership and subsidized rental housing are there to keep financial markets going, rather than being facilitated by those markets. There is little evidence that the global financial crisis has resulted in any de‐financialization of housing. There are common trajectories within uneven and variegated financialization, rather than radically different and completely unrelated forms of housing financialization.     

管理者金融危机经历影响企业金融化水平吗？——基于中国上市公司的实证研究

文章以我国2008—2017年非金融上市公司为样本，结合“烙印理论”，考察了管理者金融危机经历对非金融企业金融化水平的影响，研究发现：管理者的金融危机经历对其所在企业的金融化水平具有显著的正向影响，在一系列的稳健性检验后，该结论依然成立。且该效应在融资约束严重的企业和制度环境较好地区的企业中更加显著，而在金融危机期间遭受财务困境的企业中受到明显抑制。拓展的研究表明，经历过金融危机的管理者持有金融资产的动机并不单一，但获利动机更强烈。最后文章还发现，管理者的获利动机和管理者自信可能是金融危机经历影响企业金融化水平的关键作用机制。文章从企业微观层面拓展了非金融企业金融化水平的影响因素研究，并对企业管理者经历对非金融企业金融化的影响及作用机制研究进行了一定的探索。     

Financialization and Society’s Protective Response: Reconsidering Karl Polanyi’s Double Movement

Financialization challenges Karl Polanyi’s thesis of double movement, the thesis that efforts to extend the market evoke efforts to protect humans, nature, and means of production from market forces. Financialization refers to the increased power of financial institutions. The government protects the incomes and assets of financial institutions, but it does little to protect the incomes and assets of households, which are necessary for people to afford healthcare, education, emergencies, retirement, and so on. Polanyi criticized nineteenth-century civilization for transforming land, labor, and the means of production into commodities, using economic insecurity to motivate humans. The development of intangible property allowed business to expand the market in two ways: (i) restricting output to drive up profits and (ii) liquefying consumer assets to provide credit to consumers to increase spending. The implications of that process manifested themselves in the financial crisis of 2008. Market capitalism represented the attempt to organize commodities based on economic rationality. Similarly, the twentieth- and twenty-first-century capitalism represents the effort to “rationally” organize society according to the value of intangible assets. Both efforts failed, indicating the continued relevance of Polanyi’s thesis.
