Is it one break or ongoing permanent shocks that explains U.S. real GDP?

The relative importance of permanent versus cyclical shocks to GDP has been found to depend on the presence or absence of a single break in mean growth. We estimate unobserved components models conditional on a trend break having occurred in any specified quarter and use the Bayesian model averaging to combine the conditional estimates. We estimate a break occurred around 2006:1. Allowing for a break significantly reduces estimates of trend variance. However, enough spread remains in the posterior distribution to indicate that available data does not definitively settle the question of the relative importance of trend versus cycle.     

Loss aversion and the asymmetric transmission of monetary policy

There is widespread evidence that monetary policy exerts asymmetric effects on output over contractions and expansions in economic activity, while price responses display no sizeable asymmetry. To rationalize these facts we develop a dynamic general equilibrium model where households’ utility depends on consumption deviations from a reference level below which loss aversion is displayed. State-dependent degrees of real rigidity and elasticity of intertemporal substitution in consumption generate competing effects on output and inflation. Contractions face the Central Bank with higher responsiveness of output to interest rate changes, as well as a flatter aggregate supply schedule.     

Effects of Firm Size,Financial Leverage and R&D Expenditures on Firm Earnings: An Analysis Using Quantile Regression Approach

As documented in the literature, the effects of firm size, financial leverage, and R&D expenditures on firm earnings are inclusive. Our hypothesis is that the inconsistent empirical results of such effects may be driven by the regression models implemented in data analysis. Using the quantile regression (QR) approach developed by Koenker and Basset (1978), this study analyses S&P 500 firms from 1996 to 2005. We find that the effects of firm size, financial leverage and R&D expenditures on firm earnings differ considerably across earnings quantiles. Comparing the results from the QR approach with those from the ordinary least squares (OLS) and least absolute deviation (LAD) methods, this study further explains the puzzling relationship between firm size, financial leverage, R&D expenditures and firm earnings.     

Corporate payout policy in Australia and a test of the life‐cycle theory

We provide evidence on the frequency and size of payouts by Australian firms, and test whether the life‐cycle theory explains Australian corporate payout policies. Regular dividends remain the most popular mechanism for distributing cash to shareholders, despite a slight decline in the proportion of dividend payers since the relaxation of buyback regulations in 1998. Off‐market share buybacks return the largest amount of cash to shareholders. Dividend paying firms are larger, more profitable and have less growth options that nondividend paying firms. Consistent with the life‐cycle theory, we observe a highly significant relation between the decision to pay regular dividends and the proportion of shareholders’ equity that is earned rather than contributed.     

经济周期、前景理论与BHS资产定价模型修正

行为资产定价研究引起了国内外的广泛关注,但由于现实资本市场中诸多异象的存在,导致人们对经典资产定价模型的质疑。经济周期波动会对投资者的理性产生显著影响,而非理性投资可能引发金融危机。据此,引入经济周期这一独特视角,剖析前景理论对资产定价的作用机理;提出相关假设,对BHS模型进行修正,以适应经济周期影响下的行为资产定价问题研究。     

基于共生理论视角的创立期科技型中小企业融资问题研究

本文基于共生理论的分析框架,分析了创立期科技型中小企业融资支持体系的构成,在此基础上,分析了我国科技型中小企业融资支持体系存在的问题和不足,并据此提出了针对性的对策建议。     

基于国际比较视角的高新技术企业融资与绩效研究

金融是现代经济的核心,促进科技和金融结合对于转变经济发展方式和经济结构战略性调整具有重要意义。因此,高新技术企业的融资问题成为创新驱动发展战略实施的关键性因素。本文从总结发达国家构建多层次融资平台支持高新技术企业发展的经验出发,运用生命周期理论实证分析我国高新技术制造企业在不同生命周期中的融资顺序和结构对企业绩效的影响。结果发现,高新技术企业融资方式与其生命周期不匹配,说明高新技术制造企业在融资渠道选择方面有待改进,进一步研究还发现,政府扶持资金效率有待提高,迫切需要构建多层次融资平台支持高新技术企业发展。     

中国上市银行信贷行为的周期性研究

文章基于中国上市银行1998-2013年的数据,采用固定效应模型,对16家中国上市银行信贷行为的周期性进行了研究。研究表明,中国上市银行的信贷行为表现为阶段顺周期性和阶段逆周期性;银行规模对其周期性也有较大影响,规模较小银行或同一银行在规模较小阶段其信贷的逆周期性更显著。由于当前我国政府对宏观经济及银行行为的干预程度较大,银行监管当局所制定监管政策的针对性及有效性将受到很大削弱,因此文章建议政府的宏观经济调控政策与银行的监管政策必须相互协调,这是未来防范经济危机与金融危机,促进中国经济健康持续发展,保持中国金融系统稳健经营的必然选择。     

经济周期定期方法与研究进展

经济波动一直是宏观经济分析与预测中的经典问题,而经济周期拐点的及时识别对政府前瞻性经济政策的制定和企业投资经营战略的调整具有重要意义。鉴于我国目前尚没有权威机构对经济周期进行实时监测和发布,因而在划分经济周期和拐点识别时,往往局限于一种方法,不同方法有效性的比较缺乏一个基准参考。文章对国内外研究经济周期及其周期拐点定期的方法进行梳理和分析,依据经济周期定期方法的研究脉络,对主流的方法进行评述,并对我国经济周期定期进行展望,希望能在分析中国宏观经济波动特征和经济走势预测方面提供一些方法论参考和借鉴。
