企业金融资产配置与融资约束的缓解机制:基于流动性管理的分析

企业进行金融资产配置,一方面能够为企业提供流动性,缓解融资约束;另一方面也因投机动机而占用企业流动性资源,加剧融资约束,对实体投资造成挤压。这是形成企业金融化的"投资挤出效应"和"蓄水池效应"两种现象并存的内在机制。为衡量这种内在机制,本文使用2007—2018年我国上市公司样本,对金融资产配置的流动性管理效应展开分析。结果显示:非金融企业的金融收益会推动超额现金的持有,通过超额现金的中介效应引致了融资约束程度的缓解;而企业持有金融资产行为则产生相反的效应。进一步研究发现,在典型的公司治理机制中,无论是外部股东的投票机制,还是来自内部的代理成本与高管持股机制,都在一定程度上推动了金融资产配置产生的流动性效应。     

影响我国林业碳汇融资的主要因素及对策

随着全球气候变暖问题的逐渐严重,各国开始重新认识并重视森林的生态功能,林业碳汇逐渐成为重要的减排手段之一,林业碳汇产业也成为各国的新兴产业。针对我国林业碳汇产权不明、相关风险管理不到位、市场需求不足、投资收益相对低等问题和林业碳汇融资的的制约因素进行分析,从产权、风险、需求、收益等四个方面给出了相关的发展对策。     

CLOSED-FORM SOLUTIONS FOR OPTIMAL PORTFOLIO SELECTION WITH STOCHASTIC INTEREST RATE AND INVESTMENT CONSTRAINTS

We examine the portfolio choice problem of an investor with constant relative risk aversion in a financial market with partially hedgeable interest rate risk. The individual shadow price of the portfolio constraint is characterized as the solution of a new backward equation involving Malliavin derivatives. A generalization of this equation is studied and solved in explicit form. This result, applied to our financial model, yields closed-form solutions for the shadow price and the optimal portfolio. The effects of parameters such as risk aversion, interest rate volatility, investment horizon, and tightness of the constraint are examined. Applications of our method to a monetary economy with inflation risk and to an international setting with currency risk are also provided.     

Testing the intertemporal labor supply model: are jobs important?

The neoclassical life-cycle labor supply model assumes that hours of work are determined by labor supply choices alone and does not include a role for employers or job distinctions. An alternative model in which employers have an interest in employee hours and changing jobs is costly may reconcile weak and conflicting evidence regarding the neoclassical model. An important implication of such an alternative is that individuals may face hours constraints on a job and thus can choose hours freely only between jobs. This paper tests several implications of the neoclassical model against this alternative model of hours determination. Using a unique panel of individuals and jobs constructed using data on women from the 1988–1992 Panel Study of Income Dynamics, I compare hours variances and labor supply elasticities measured within and between jobs. Results provide some evidence against the neoclassical model and suggest that ignoring the role of employers in determining hours of work can lead to downward bias in estimates of labor supply elasticities.     

CORPORATE CAPITAL STRUCTURE AND HOW SOFT BUDGET CONSTRAINTS MAY AFFECT IT

Abstract.  This survey paper examines existing theories of capital structure and related empirical tests with the aim to derive theoretical as well empirically testable predictions about the implications of the soft budget constraint for corporate capital structure. We show that the soft budget constraint syndrome is relevant for a variety of institutional environments, from central planning to capitalist economic systems, and consider features of company financing patterns in various institutional contexts. Special attention is paid to emerging and transition economies where, with the development of financial markets, companies reduce their financial dependence on the state and begin to borrow from a variety of sources. However, due to the persistence of soft budget constraints, corporate capital structure in transition and emerging economies may still deviate significantly from the capital structure of companies operating under hard budget constraints.     

Financial Constraints and Other Obstacles: are they a Threat to Innovation Activity?

Summary  In this paper we examine the importance of financial and other obstacles to innovation in the Netherlands using statistical information from the CIS 3.5 innovation survey. We report results on the effect of these obstacles on the firms’ decision to abandon, prematurely stop, seriously slow down, or not to start an innovative project. These results are compared with those from other studies in the Netherlands and other countries. We end with a discussion of policy measures that have been taken to overcome, or at least attenuate these obstacles, such as R&D tax incentives, venture capital financing and policy mix packages.      

Fiscal policy and private consumption behaviour: The Spanish case

In this article we analyse whether the Ricardian equivalence hypothesis is a valid approximation for Spains economic reality or whether there exist deviations from that situation which would be more in line with the conventional Keynesian perspective of the effects of debt on private consumption-savings decisions.Our aim is to contribute to the rather sparse empirical literature on the subject for the Spanish case. The analysis is based on annual aggregate data for Spain covering the years 1955 to 2000, and uses both the structural and the Euler equation approaches to test the neutrality proposition, and is thus to be considered as a generalization of foregoing work on the Spanish economy.The findings indicate that support for Ricardian equivalence is mixed, while we also find very little support for the Keynesian specification of consumption and fiscal policy.First revision received: March 2003 / Final version received: October 2003The authors wish to thank M.

Short Sale Constraints and Dispersion of Opinion: Evidence from the Indian Equity Market

Short sale constraints can inflate market prices, as bearish investors cannot act on their market views. The paper uses data from the Indian equity market to test whether opinion dispersion leads to higher overpricing when short sales are prohibited. The Indian equity market provides a natural testing environment, as short sales were banned between 2001 and 2008. The empirical results offer supportive evidence of the relation between opinion dispersion and overpricing in a market with short sale constraints.     

税收有效性、征税权归属与宪法性约束

税收的有效性一方面蕴含着效率、公平与稳定的积极职能,另一方面包含着对产权结构的效益负责的消极职能。税收有效性由国家征税权负责实施,征税权归属构成税收有效性的政治基础,征税权代议制由于在其内部结构中设置了平衡机制而成为实践税收有效性的现代制度基石。伴随着政治结构中利益集团的成型,征税权代议制导致多数联盟对少数者的歧视与强占,为确保税收有效性,需要从程序和实体两个侧面对征税权施加外在的宪法性约束。     

“走出去”战略下中国对外直接投资的母国约束研究

本文以一般性的对外直接投资决定因素为模板,改进OLI折衷模型,引入"母国约束",在总结中国近年来对外直接投资的发展历程及潜在的动因的基础上,构建了中国对外直接投资的母国决定因素的分析框架。然后,结合中国的经济发展水平、开放程度和政策措施,分析了中国对外直接投资的驱动因素及其影响机制,据此设定若干假设并一一进行了验证。同时,从中国的"走出去"战略出发,分析了中国对外投资的政策因素影响。
