中国上市公司IPO后经营业绩变化情况的分析——来自A股公司的经验数据

本文以1999￣2000年在沪、深两市首发上市的216家A股公司为样本,以这些公司从首发前一年延伸至2003年的数据,研究了中国A股上市公司IPO前1年至后3年的收入、成本、费用及效益的变化。研究发现:与上市前相比,中国A股公司IPO后的主营业务收入、主营业务成本、期间费用等绝对数指标均显著上升,而主营业务收入营业利润率却显著下降;造成业绩下降因素很多,其中最直接的主要原因是公司上市后成本、费用的大幅度上升。     

Accounting for Environmental Influences in Stochastic Frontier Models: With Application to International Airlines

The principal aim of this paper is to measure the efficiency of international airlines. We obtain measures of technical efficiency from stochastic frontier production functions which have been adjusted to account for environmental influences such as network conditions, geographical factors, etc. We observe that two alternative approaches to this problem have been proposed in the efficiency measurement literature. One assumes that the environmental factors influence the shape of the technology while the other assumes that they directly influence the degree of technical inefficiency. In this paper we compare the results obtained when using these two approaches. The two sets of results provide similar rankings of airlines but suggest differing degrees of technical inefficiency. Both sets of results also suggest that Asian/Oceanic airlines are technically more efficient than European and North American airlines but that the differences are essentially due to more favourable environmental conditions. Nevertheless, it is among Asian companies that the major improvements in managerial efficiency (technical efficiency with environmental factors netted out) took place over the sample period (1977–1990).     

Bounding the benefits of stochastic auditing: The case of risk-neutral agents

Summary. In the context of a costly-state-verification model with a risk-neutral agent having limited liability, it has been postulated that allowing stochastic auditing reduces the asymmetric information problem to a trivial one: i.e., the first best can be approached arbitrarily closely with feasible contracts. This paper proves the postulate to be false: the surplus from feasible contracts is bounded strictly below the first-best surplus level. The bound is straightforward to compute in examples. The paper thus removes a justification for the restriction to deterministic auditing commonly made in the literature. Received: July 18, 1997; revised version: February 23, 1998     

Promote Competitive Neutrality to Facilitate China’s Economic Development:Outlook,Policy Simulations,and Reform Implementation-A Summary of the Annual SUFE Macroeconomic Report(2019-2020)

Twenty nineteen(2019)marked another year of lethargic growth in the Chinese economy amidst escalated internal and external complexities.Internally,the country's macroeconomic landscape was overcast continuously by fallen consumption growth,plunged growth in manufacturing investment,rapid accumulation of household debt,risen income inequality,and the overhang of local government debt.The nation's external conditions did not fare any better,with drastically declined growth in imports and exports,continued trade tensions with the US,and weakened external demand.Based on the IAR-CMM model,which takes account of both cyclical and secular factors,the baseline real GDP growth rate is projected to be 6.0%in 2020(5.9%using more reliable rather than the official data),with a downside risk.Alternative scenario analyses and policy simulations are conducted,in addition to the benchmark forecast,to reflect the influences of various internal and external uncertainties.The findings emanated from these analyses lead us to stress the importance and urgency of deepening reform to achieve competitive neutrality for China’s transformation into a phase with sustainable and high-quality development.     

我国外部均衡调节中的估值效应分析

世界金融一体化促进各国对外资产与负债迅速增长。资产价格的非预期变化使一国对外净资产更多地暴露于资本收益和损失风险中,因此,如何实现有利于一国外部均衡的估值效应就显得日益重要。本文对估值效应的理论模型和计量方法进行梳理,并对我国对外净资产变化中的估值效应进行实证分析,结果发现存在负的估值效应,表明我国通过经常项目盈余所聚积的大量资源正在不断地向国外无偿转移,这就要求对外资产管理水平稳步提高。     

Microfoundations

This paper argues that the microfoundations programme can be understood as an implementation of an underlying methodological principle—methodological individualism—and that it therefore shares a fundamental ambiguity with that principle, viz, whether the macro must be derived from and therefore reducible to, or rather consistent with, micro-level behaviours. The pluralist conclusion of the paper is not that research guided by the principle of microfoundations is necessarily wrong, but that the exclusion of approaches not guided by that principle is indeed necessarily wrong. The argument is made via an examination of the advantages claimed for dynamic stochastic general equilibrium models, the relationship between parts and wholes in social science, and the concepts of reduction, substrate neutrality, the intentional stance and hypostatisation.     

The Goals of Carbon Peaking and Carbon Neutrality and China’s New Energy Revolution

Based on the full consideration of both domestic and global environments and conditions, the adherence to the conviction that lucid waters and lush mountains are invaluable assets, and the comprehensive weighing of pros and cons, the Chinese government has made a major strategic decision to achieve the goals of carbon peaking and carbon neutrality, which is crucial to the overall green transformation of the economy and society and the long-term benefits of the Chinese nation. With the new energy revolution and energy mix diversification driven by the carbon peaking and carbon neutrality goals, nonfossil energy sources centered on photovoltaic energy will gradually dominate the energy mix, while the status of electricity and hydrogen energy will be significantly enhanced and the consumption of coal and petroleum will decline significantly. Carbon peaking and carbon neutrality goals are both challenges and opportunities for China. Specific challenges are embodied in the large pressure of economic and energy restructuring, the rising manufacturing costs, the difficulties in withdrawing coal-fired power stations, the possibility of unstable grid operations due to large-scale integration of photovoltaic and wind power into the power distribution network, and the supply risks of key metals, while specific opportunities are emerging in the strong competitiveness of photovoltaic and wind power equipment, lower dependence on foreign petroleum and gas supply and accelerated low-carbon green transformation. China should strengthen the top-level design of the path to achieve carbon peaking and carbon neutrality, encourage innovation of green low-carbon technologies, accelerate economic and energy restructuring, strictly restrict the construction of new high-emission and energy-intensive projects, and steadily promote the adjustment and withdrawal of the existing high-emission and energy-intensive projects.     

基于银行流动性管理视角的宏观审慎与货币政策协调研究

本文从商业银行流动性管理视角出发,探究银行微观主体行为如何影响宏观审慎与货币政策的协调。我们借鉴净稳定资金比例的设计理念,将商业银行的流动性管理行为纳入传统理论模型,刻画出两种流动性管理行为对货币政策信贷传导渠道效率的潜在影响及传导路径。在此基础上,采用我国50家商业银行2012年第1季度—2018年第2季度面板数据进行实证检验。我们发现,银行为提升长期流动性水平而进行的优化信贷资产结构的行为,能够显著提高货币政策传导效率。但是,部分净稳定资金比例较低的股份制银行和城市商业银行调整非信贷资产结构的行为则有可能降低货币政策传导效率。因此,在执行既有流动性监管措施的同时,关注与引导银行资产结构调整方式,对增强宏观审慎与货币政策的协调大有裨益。     

Analyzing quantile spillover effects among international financial markets

This paper investigates the quantile-based spillover effects among 17 stock markets from January 1993 to January 2022, utilizing a quantile approach based on the variance decomposition of a quantile vector autoregression (QVAR) model. Compared with the traditional mean-based spillover measures, this new quantile approach allows for a nuanced investigation of spillovers at every quantile and capture spillovers under extreme events. The results show that: (1) the total spillover is high and exhibits strong time-varying characteristics, and the tail spillover is higher and more complex in scale and direction; (2) the spillover at each quantile level shows an upward trend, especially during the 2008 crisis and the COVID-19 epidemic; (3) developed countries (or regions) are the net exporters of stock market spillovers, while the developing countries are the net importers; and (4) the 17 stock markets constitute different local financial networks, which may be related to economic conditions and geographical location.
