Fiscal and monetary interdependence

Where classical economics integrates the quantity theory of money with the concept of Ricardian equivalence, the tendency of recent macroeconomic presentations is to focus either upon money and inflation or upon taxation and debt. That neglect of classical monetary–fiscal integration is surprising, given an initiative by the International Monetary Fund that set credit, money, and fiscal policy within a single structure. This article places those ‘credit counterparts of broad money’ in the context of the Great Depression and the recent global financial crisis. The upshot is a set of conclusions: that, to counter the prospect of deflation, quantitative easing is a weak policy response; that fiscal deficits are better; and that cuts in taxation are preferable to increased government spending.     

ON THE PROFITABILITY OF RESALE PRICE MAINTENANCE WHEN DEMAND IS UNCERTAIN

A previous study finds that in a market where a manufacturer faces uncertain demand and sells to consumers through competitive retailers, the manufacture wishes to support adequate retail inventories by imposing resale price maintenance (RPM). I show that if retail inventories are allocated to consumers through first‐come‐first‐served rule rather than efficient rationing rule in the game with unconstrained retail competition, imposing RPM may not be profitable. It may not encourage more retail inventories either. RPM may also lower consumer surpluses and social welfare. This study casts some doubt on the demand uncertainty theory that supports RPM.     

要素价格扭曲与异质性企业区位选择——基于泊松面板回归的实证研究

采用生产函数法,论文详细测算了1998-2007年中国大陆除西藏以外267个城市的要素价格扭曲。接下来,运用中国工业企业数据库中的数据,构建泊松面板回归模型考察了要素价格扭曲对于不同生产效率企业选址产生的影响。按行业、区域分别划分样本以及稳健性检验均表明:(1)较高的要素价格扭曲水平对于该地区新进入的低效率企业的期望值具有显著为正的影响,而对于该地区新进入的高效率企业的期望值则具有显著为负的影响;(2)地区运输成本和环境管制强度对于不同效率企业选址的影响存在异质性,而其他区域特征解释变量对于选址企业数量的影响均显著,且方向与理论预期一致。     

高管连锁网络与股价同步性

本文以2009—2018年中国A股上市公司为研究样本,考察了高管连锁网络对公司股价同步性的影响。研究发现：高管连锁网络会提高公司的股价同步性,处于高管连锁网络越中心位置的上市公司,其股价同步性越高;从趋同性和信息透明度两个方面进一步分析高管连锁网络对股价同步性的作用机制,发现高管连锁网络并非通过降低公司透明度这一途径对股价同步性产生影响,而是因为连锁高管加强了上市公司间的行为学习、信息和资源的共享,促使公司间基础特征趋同,进而提高了公司的股价同步性;根据联结类型的不同将高管连锁网络划分为董事网络、监事网络和高管网络,实证结果表明高管网络对股价同步性的提升效应最大,董事网络次之,监事网络对股价同步性无显著影响;区分产权性质和法治环境后发现,在国有企业和所处法治环境较差的企业中,高管连锁网络提高股价同步性的效应更显著。研究结论为提升资本市场信息效率提供了理论支撑。

结构失衡、供给约束与农产品涨价

近年来我国农产品价格大幅上涨,民众生活压力骤然增大.究其根源,见仁见智.文章认为,中国社会经济结构发展失衡是导致农产品价格大幅上涨的主要原因.多年来,受“重工轻农”思想观念的主导,各级政府以牺牲“三农”来支撑高速工业化和城市的快速扩张,导致了耕地面积和“职业农民”的锐减,农产品的生产能力严重不足.因此,必须修正宏观经济政策,加强农业的基础地位.

中小企业研发困境的博弈分析

知识经济时代，企业自主研发是增强其竞争力的必经途径。而在国内，众多中小企业对研发投入持消极态度，尽管政府多方鼓励，但收效不大，且企业在自主研发的投入方面与发达国家有着较大的差距。可从严格保护研发成果、协作研发与加大政府的政策优惠力度等方面对中国中小企业的研发投入情况进行改进。     

Mixed Market Competition in a Quality Differentiated Duopoly Model An Approach to Banking Sector

This paper attempts to develop a theoretical framework to investigate the competitive implications of quality choices of financial institutions whereby they charge prices to consumers based on their willingness to pay for the service qualities in the mixed market scenario under vertical product differentiation model. Initially, it analyzes benchmark equilibrium solutions of monopoly and duopoly to establish the degree of quality differentiation between two private banks in an uncover market configuration. Further, it estimates the quality differentiation between private and public banks, and examines the interaction between two market structures keeping public bank as both leader and follower, and then measures the social welfare from different prospectives. The explicit operation of two stages Nash equilibrium game forecasted that public banks＇ monopoly seems to be still better than a private banking, and it is socially optimal. The outcome demonstrates a significant importance of vertical quality differentiation for policy implication in banking industry and provides an insight on the reasons of particular co-existence of public and private banking services in the specified location. In this context, it is concluded that the presence of public banks in banking industries is a crucial condition for obtaining the higher range of social welfare.
