关系质量对企业知识创造绩效的作用机理：一个被调节的中介模型

基于嵌入性视角，分别引入知识转移、合作模式作为中介变量和调节变量，深入探究关系质量影响企业知识创造绩效的内在机理。利用277份来自全国多地的制造业及高新技术企业调查问卷，采用多元回归方法进行实证研究。结果表明：经济型和社会型关系质量均正向影响企业知识创造绩效；社会型关系质量通过元素知识和架构知识转移正向影响企业知识创造绩效。在契约治理模式下，经济型关系质量更倾向于通过元素知识转移正向影响企业知识创造绩效；在股权治理模式下，社会型关系质量更倾向于通过架构知识转移正向影响企业知识创造绩效。     

Optimal investment with fixed financing costs

Models with a premium on external finance produce counterfactual predictions about liquidity management. We address this shortcoming by introducing a fixed cost of increasing external finance into an otherwise standard investment/financing problem. This additional financial friction is well-motivated by case studies and our analysis shows that it generates more realistic predictions about liquidity management: firms hold external finance and idle cash simultaneously, and may invest an additional dollar of cash flow in liquidity rather than repaying external funds or investing in productive capital. In addition to better fitting the stylized facts about the time-series and cross-sectional pattern of liquidity holding, these results may help shed light on the fragility of estimates of investment–cash flow sensitivities.     

The liquidity effects of foreign exchange intervention

This paper examines the effectiveness of foreign exchange intervention in a two-country, two-currency, general equilibrium model that allows for liquidity effects. Both sterilized and non-sterilized intervention operations have significant impacts on the allocation of liquidity in international financial markets. Whether intervention is successful in moving the exchange rate in the desirable direction depends upon the degree of sterilization of intervention and the intratemporal elasticity of substitution of the consumption goods. The model shows that there exist circumstances in which the response of exchange rate to intervention is ‘perverse’ as documented in the empirical literature.     

移动支付对中国家庭储蓄率的影响

中国的高储蓄问题由来已久,降低家庭储蓄率、提高消费有助于形成以国内大循环为主体、国内国际双循环相互促进的新发展格局。本文基于2017年和2019年中国家庭金融调查(CHFS)数据,实证研究了移动支付对中国家庭储蓄率的影响。结果表明,移动支付显著降低了家庭储蓄率。进一步研究发现,缓解流动性约束、信贷约束和扩大社会网络是移动支付降低家庭储蓄率的主要途径。此外,移动支付显著降低家庭为应对健康风险、医疗风险、失业风险、收入风险等不确定性而进行的预防性储蓄。地区异质性分析显示,移动支付对家庭储蓄率的影响在西部地区、四五线城市、农村地区更大。家庭特征异质性分析显示,移动支付对家庭储蓄率的影响在农业户口家庭、中低收入家庭、低受教育水平家庭中效果更加突出。本文研究为理解中国高储蓄问题提供了新的视角,可为制定相关政策提供参考依据。     

论保单持有人最后一道安全屏障:保险保障基金

保险公司退出市场的形式一般分为解散、撤消、破产等。从经济角度来看，保险公司退出的核心问题是保险公司的破产。出于保险公司的经营涉及到多方面的利益，如果简单允许保险公司破产，必然影响整个金融体系的稳定和社会经济的正常发展。因而，在引入竞争机制的同时，还必须建立科学的保险保障基金制度。     

论一种"新"型的关税同盟:混合型关税同盟

国际经济学界流行的看法,即认为贸易转移型关税同盟既可导致贸易创造又可导致贸易转移,这是不正确的,这种所谓的贸易转移型关税同盟实际上是一种混合型关税同盟。一个混合型关税同盟包含了一个纯贸易创造型关税同盟和一个纯贸易转移型关税同盟,关税同盟的建立能否给某个加盟国带来福利的增加,取决于这两股相反作用力的相对强弱。若贸易创造大于贸易转移,则福利增加,反之亦然;若两者相当,则还能出现福利不变的情况。     

关于解决流动性过剩问题的初步思考

本文从流动性的内涵和外延入手,分析了我国流动性过剩的全球背景和我国流动性过剩的表现及结构性特点,提出了解决流动性过剩,要坚持"市场为主、各方联动、化多为少、化少为多、标本兼治、综合解决"的思路,指出当前重点是解决经常账户顺差过大,流动性过剩的来源问题,以及农村地区资金匮乏,导致资金配置结构性失衡的问题。     

论社会主义社会的劳动和劳动价值

本文探讨了社会主义社会劳动和劳动价值理论。文中指出 ,必须全面、准确地把握马克思关于价值创造的理论与方法 ;澄清传统政治经济学中一系列并不完全符合马克思原意、更脱离现实经济生活的观念 ;发展马克思主义的劳动价值理论 ,扩展价值创造和生产性劳动的领域     

Strategic trading and learning about liquidity

Many practitioners point out that the speculative profits of institutional traders are eroded by the difficulty in gauging the price impact of their trades. In this paper, we develop a model of strategic trading where speculators face such a dilemma because of incomplete information about time-varying market liquidity. Unlike the competitive market makers that they trade against, informed traders do not know the distribution of liquidity (“noise”) trades. Instead, they have to learn about liquidity from past prices and trading volume. This learning implies that strategic trades and market statistics such as informational efficiency are path-dependent on past market outcomes. Our paper also has normative implications for practitioners.     

Money and exchange rates in the Grossman-Weiss-Rotemberg model

We analyze the impact of monetary policy on inflation, interest rates and exchange rates in a model with segmented asset markets developed by Grossman and Weiss (1983) and Rotemberg (1984, 1985). We find parameters for which real and nominal exchange rates in this model are (1) much more volatile than interest rates, inflation rates, and money growth rates, (2) highly correlated with each other, and (3) highly persistent. While this model fails to match the data in other important respects, it illustrates a potentially useful approach to modelling exchange rate behavior.
