转型期国有企业改革的伦理困惑与破解--基于中国的实践和西方的经验

经济转型意味着旧的"社会契约"被打破,而新的契约尚未订立,作为企业行为调控机制的伦理作用得以彰显.我们在分析市场经济体制下,西方企业在不同管理时代的"伦理"与"绩效"关系的基础上,阐明企业伦理本身的特有属性及经营绩效的内涵;同时结合中国国有企业目前面临的伦理困惑,认为国有企业要破解这些伦理困惑,就必须根据变化了的现实对其管理伦理进行合理定位,以"社会期望"为前提谋求企业与社会的和谐,以市场经济游戏规则为准谋求企业之间的和谐,以人本管理为依托达到企业与员工关系的和谐统一、以生态优先为基准谋求企业与自然的伙伴关系,以与全球经济接轨为基础实现国有企业组织个性化,以"权威声誉、伦理声誉"营造社会激励伦理行为的氛围.     

中小企业融资困境的经济学解释

中小企业的迅速发展,使我国在整体经济不利的环境下保持了较快的增长速度。但是中小企业在取得巨大发展的同时,在信贷市场上却面临着商业银行的信贷配给,陷入融资难的困境。文章试图从信贷配给的视角解释商业银行面对中小企业的信贷配给,用二元经济模式下的双重信贷配给解释中小企业的融资困境,并且提出中小企业解决融资困境的一条可行性途径,即市场利率化,信贷信息联网以及信贷担保体系。     

Monetary Policy,Trend Inflation,and Unemployment Volatility

The literature has long agreed that the DMP model (after Diamond 1982, Mortensen 1982, Pissarides 1985) with search and matching frictions in the labor market can deliver large volatilities in labor market quantities, consistent with empirical data, only if there is at least some wage stickiness. I show, however, that the model can deliver nontrivial volatilities without wage stickiness, as long as it has price dispersion and nonzero long‐run inflation rates. I find that by keeping inflation at a positive rate, monetary policy may be accountable for the large standard deviations observed on labor market variables. In addition, the Shimer (2005) puzzle disappears under monetary policy shocks.     

Is insurance normal or inferior? -A regret theoretical approach-

This study considers how changes in wealth affect insurance demand when individuals suffer disutility from regret. Anticipated regret stems from a comparison between the ex-post maximum and actual wealth. We consider a situation wherein individuals maximize their expected utility incorporating anticipated regret. The wealth effect on insurance demand can be classified into the risk and the regret effects. These effects are determined by the properties of the utility function and the regret function. We show that insurance can be normal when individuals place weight on anticipated regret, even though the utility function exhibit decreasing absolute risk aversion. This result indicates that regret theory is a possible explanation to the wealth effect puzzle, in which insurance is normal from empirical observation, but it should be inferior by theoretical prediction under expected utility theory.     

Liquidity shocks: A new solution to the forward premium puzzle

The frequent empirical failure of uncovered interest rate parity raises a question that has not been definitively answered: why do predictable excess returns on currencies persist in competitive currency markets? Supported by data from nine major currencies for 1978:08–2019:09, I provide a novel resolution to this enduring forward premium puzzle by building on the financial economics literature that explores the economic implications of limited access to capital markets. A liquidity shock, or the urgent demand for liquidity by credit-constrained arbitragers liquidating bond holdings, causes losses from sudden drops in bond prices. Arbitragers require a liquidity premium to compensate for potential losses that vary directly with the interest rate. It is this liquidity premium that explains persistent excess returns on currencies. I argue for policies favoring a low interest rate environment and macroprudential controls that ease liquidity constraints to increase the efficiency of international capital markets by reducing the liquidity premium.     

Non-linear exchange rate relationships: An automated model selection approach with indicator saturation

This paper examines whether the explanatory power of exchange rate models can be improved by allowing for cross-country asymmetries and non-linear effects of fundamentals. Both appear to be crucial. The samples include the USD versus pound and yen from 1982:10 to 2013:10, and automated model selection is conducted with indicator saturation. Several non-linear effects are significant at 1%. Further, many of the indicators present in the linear models are eliminated once allowing for non-linearities; suggesting some of the structural breaks found in previous work were an artifact of the misspecified linear functional form. These conclusions are robust to estimation using principal components.     

The savings multiplier

A theory of macroeconomic development based on the novel concept of savings multiplier is developed. Capital accumulation changes relative prices, amplifying incentives to save as the economy grows. The savings multiplier hinges on two mechanisms. First, accumulation raises wages and leads to redistribution from the consuming old to the saving young. Second, higher wages raise the price of old-age care and, in anticipation of this, the young save more. Our theory captures important aspects of China׳s development and suggests new channels through which the one child policy and the dismantling of social benefits have fueled China׳s savings rates.     

县乡财政困境与财政立宪主义

中国县乡财政困难背后蕴含着深刻的政府与社会、政府之间的关系的矛盾。以往在技术层面上修修补补式的改革不能从根本上解决问题。因此,本文主张采取财政立宪的制度创新思路。包括两个方面的内容,一方面是通过完善法治和建立有效的民主决策监督机制,实现纳税人对政府的根本约束和监督;另一方面是规范政府间的财政分配关系,抑制政府间的过分自利倾向,实现政府间的合理分权与制衡。     

商业年金消费决策的行为经济学分析

商业年金是我国养老保险体系的重要组成部分,虽然近年来我国在政策层面不断推动商业年金的发展,但是我国居民的商业年金需求仍然十分低,存在“年金谜题”现象。本文从行为经济学的视角展开对商业年金消费决策的分析,首先从理论层面阐述了行为因素对商业年金消费决策的影响机制,随后设计调查问卷收集个体数据,从实证层面进行了验证。结果发现,主观概率、心理账户、信息感知、金融素养等行为因素会显著影响个人的商业年金消费水平,其他客观因素如性别、年龄、婚姻状况、风险态度以及收入水平等也会显著影响个人的商业年金消费水平。基于本文研究结果,认为未来商业年金回归保障属性、弱化个人账户概念以及发展保险咨询服务等可以带来商业年金需求的提升。
