我国金融发展与经济增长关系的区域差异分析——兼论分税制改革对金融发展与经济增长关系的影响

本文利用1979-2003年的省级面板数据，将我国分为东、中、西三大区域，考察了金融发展对经济增长的影响，结果表明：把国有商业银行贷款占GDP的比例作为金融发展的衡量指标对三大地区人均GDP均具有显著的正相关性，金融发展促进经济增长的理论在我国同样成立；但金融发展与实体经济部门之间均不存在良性互动的关系，其对经济增长的贡献仅仅停留在增加资本积累上，对资本配置效率的改善作用不大；1994年的分税制改革对金融发展促进经济增长的作用造成了显著的负面影响。因此，我国的金融体制改革需要将金融体制改革、国有企业改革、财税体制改革和政府体制改革纳入同一个分析框架中进行。     

Revenue Sharing versus Expenditure Sharing in a Federal System

Problems of intergovernmental policy coordination can take many forms and are becoming increasingly important with continuing economic integration. In this paper we focus on the fiscal competition problem where the non-cooperative choice of taxes and transfers among governments typically leads to a suboptimal outcome. We look at the effect of two widely used corrective policies: revenue sharing and expenditure sharing (or intergovernmental matching grants). Our main result is that these two corrective policies have opposite effects depending on the form of competition between governments, namely whether governments compete in taxes or expenditures. More precisely, for any form of competition, revenue sharing is desirable exactly when expenditure sharing is not and vice versa. The implication is that the choice of the optimal corrective policy requires a complete understanding of the underlying non-cooperative behavior among governments. Our second main result is that neither revenue sharing or expenditure sharing can be sustained as a Nash equilibrium among governments, although all governments would benefit from one of these two corrective policies. Central intervention is therefore inevitable unless governments can pre-commit to the optimal corrective policy before setting their fiscal policies.     

The composite iteration algorithm for finding efficient and financially fair risk-sharing rules

We consider the problem of finding an efficient and fair ex-ante rule for division of an uncertain monetary outcome among a finite number of von Neumann–Morgenstern agents. Efficiency is understood here, as usual, in the sense of Pareto efficiency subject to the feasibility constraint. Fairness is defined as financial fairness with respect to a predetermined pricing functional. We show that efficient and financially fair allocation rules are in one-to-one correspondence with positive eigenvectors of a nonlinear homogeneous and monotone mapping associated to the risk sharing problem. We establish relevant properties of this mapping. On the basis of this, we obtain a proof of existence and uniqueness of solutions via nonlinear Perron–Frobenius theory, as well as a proof of global convergence of the natural iterative algorithm. We argue that this algorithm is computationally attractive, and discuss its rate of convergence.     

浅析“互联网+”时代分享经济的大力发展

随着互联网的快速发展,分享经济逐渐由传统向行、住等多种领域渗透,获得人们的广泛关注和使用,正处于经济发展的风尖浪口。虽然分享经济在我国发展较快,但是起步较晚,在发展过程中也会受到一些阻碍,本文主要介绍在"互联网+"时代分享经济发展的重要意义,当前的主要表现形式以及如何更好地发展。     

The going public decision and the structure of equity markets

The industries in which listed firms are concentrated in less developed equity markets are not random, nor entirely explained by the underlying composition of production. Listed firms and market capitalization are disproportionately concentrated in industries with low beta (measured with their beta with the market portfolio in the U.S.). We document a strong positive relationship between the industry-weighted country beta and the degree of market development across countries. Recent IPO activity confirms the result since new listings have higher betas than the average firm already in the market.     

Information Sharing and Financial Sector Development in Africa

This study investigates the effect information sharing has on financial sector development in 53 African countries for the period 2004 to 2011. Information sharing is measured with private credit bureaus and public credit registries. Hitherto unexplored dimensions of financial sector development are employed, namely: financial sector dynamics of formalization, informalization, and non-formalization. The empirical evidence is based on Ordinary Least Squares (OLS) and Generalized Method of Moments (GMM). The following findings are established. Information-sharing bureaus increase (reduce) formal (informal/non-formal) financial sector development. In order to ensure that information-sharing bureaus improve (decrease) formal (informal/non-formal) financial development, public credit registries should have between 45.45 and 50% coverage while private credit bureaus should have at least 26.25% coverage.     

Does risk sharing increase with risk aversion and risk when commitment is limited?

I consider a risk-sharing game with limited commitment, and study how the discount factor above which perfect risk sharing is self-enforcing in the long run depends on agents׳ risk aversion and the riskiness of their endowment. When agents face no aggregate risk, a mean-preserving spread may destroy the sustainability of perfect risk sharing if each agent׳s endowment may take more than three values. With aggregate risk the same can happen with only two possible endowment realizations. With respect to risk aversion the intuitive comparative statics result holds without aggregate risk, but it holds only under strong assumptions in the presence of aggregate risk. In simple settings with two endowment values I also show that the threshold discount factor co-moves with popular measures of risk sharing.     

Knowledge sharing in the hospitality context: The roles of leader humility,job crafting,and promotion focus

Grounded in a view of self-transcendence, leader humility is expected to influence employees to acquire and share knowledge for self-development. This study investigates how and when leader humility activates hospitality employees’ knowledge collection and knowledge donation. The dataset was built from 674 employees and 87 direct managers working in the Vietnam-based hotel organizations. Analyzed through multilevel structural equation approach, the data provided support for the positive relationships between leader humility and knowledge collection and donation behaviors among hospitality employees. The three dimensions of job crafting functioned as mediators for these relationships. Employees’ promotion focus played a moderating role for the relationships between leader humility and seeking resources and challenges, but did not interact with leader humility to impact job demands. The discussion on the implications for hospitality scholars and practitioners from the research findings is presented.     

The shared environmental responsibility principle: new developments applied to the case of marine ecosystems

Estuaries provide advantageous sites for both harbors and fish habitats. In many countries, harbor expansion in estuaries contributed to the decline of fish populations with impacts at the global scale. Restoring these habitats is important to prevent a global biodiversity crisis but is costly and potentially unaffordable for polluters under the Polluter Pays Principle. Such affordability issues prompt decision-makers to reduce environmental targets of restoration programs. Harbor infrastructures destroy fish habitats but generate benefits for society and contribute to the public interest, raising some questions on who is responsible for environmental degradations and who can afford environmental restoration costs? One way to allocate restoration costs is to analyze the amount of harbor services consumed by economic sectors. This paper addresses these questions by computing burden sharing scenarios with an input–output matrix. These scenarios are simulated under the shared responsibility principle to distribute restoration costs among stakeholders in the Seine estuary, France.
