国企利润分配制度改革与资本积累

依据鲍尔斯等学者对剩余产品的相关论述,本文将国企利润分配制度改革分为利润控制主体改革和利润使用方式改革,按照这两个维度,立足于《资本论》中的理论与方法,建立了马克思主义理论框架,对国企利润分配制度改革作出了新的阶段划分,并解释了新中国成立以来国有工业企业的长期资本积累历程。本文的基本结论是,利润控制主体改革和利润使用方式改革均影响资本积累。当前,深化国有资本经营预算改革面临的真正挑战是预算支出结构改革将导致公平与效率的权衡,在民生支出提高的情况下需要保证国有资本经营预算的相对独立性,切实提高国有资本经营生产性支出效率。     

Macroeconomic risk and the cross-section of stock returns

We develop a conditional version of the consumption capital asset pricing model (CCAPM) using the conditioning variable from the cointegrating relation among macroeconomic variables (dividend yield, term spread, default spread, and short-term interest rate). Our conditioning variable has a strong power to predict market excess returns in the presence of competing predictive variables. In addition, our conditional CCAPM performs approximately as well as Fama and French’s (1993) three-factor model in explaining the cross-section of the Fama and French 25 size and book-to-market sorted portfolios. Our specification shows that value stocks are riskier than growth stocks in bad times, supporting the risk-based story.     

A Study on the Effect of Financial Inclusion on the Relationship Between Income Inequality and Economic Growth

In this article, we attempt to estimate whether financial inclusion, expressed as financial accessibility, has a positive effect on reducing income inequality. Furthermore, we estimate the effect of such financial inclusion on economic growth by reducing income inequality. From the results of our empirical analysis, we can draw the following three conclusions. First, income inequality has a very negative effect on GDP growth. The negative relationship between income inequality and GDP growth is strong in low-income countries. In addition, income inequality has a stronger effect on reducing economic growth in high-fragility countries. Second, progressivity is not a major factor in reducing income inequality in low-income countries or in high-fragility countries. Finally, financial inclusion improves the relationship between income inequality and economic growth. The reduction in income inequality through financial inclusion changes the negative relationship between income inequality and economic growth into a positive relationship. This trend is stronger in high-fragility countries than in low-fragility countries.     

A two-stage stratified Warner’s randomized response model using optimal allocation

This paper applies Kim and Wardes (2004) stratified Warners randomized response model to Mangat and Singhs (1990) two-stage randomized response model. The proposed stratified randomized response model has an optimal allocation and a large gain in precision. Hence, the estimator based on the proposed method is more efficient than Kim and Wardes (2004) and Mangat and Singhs (1990) estimators under the conditions presented in both the case of completely truthful reporting and that of not completely truthful reporting by the respondents.     

美国信用消费法律制度及其对中国的启示

美国作为世界上信用消费制度最发达的国家之一,其信用消费立法一直备受关注。2009年的《金融改革方案》虽然确立了消费者保护的目标,但也给经济发展带来了更大的不确定性。在信用消费立法联邦化的趋势下,州立法实施更为严格的消费者保护标准受到联邦优先权的重压,也从实质上削弱了对金融消费者的保护力度。中国应当借鉴美国信用消费制度,确立政府的监管目标和价值取向,以国家立法和地方立法相结合作为主要立法模式,完善信息披露制度并建立完备的信用评估体系,设立专门的信用消费者保护机构,以更好地维护消费者权益。     

Financial crisis and stock market efficiency: Empirical evidence from Asian countries

This paper empirically investigates the effects of the 1997 financial crisis on the efficiency of eight Asian stock markets, applying the rolling bicorrelation test statistics for the three sub-periods of pre-crisis, crisis, and post-crisis. On a country-by-country basis, the results demonstrate that the crisis adversely affected the efficiency of most Asian stock markets, with Hong Kong being the hardest hit, followed by the Philippines, Malaysia, Singapore, Thailand and Korea. However, most of these markets recovered in the post-crisis period in terms of improved market efficiency. Given that the evidence of nonlinear serial dependencies indicates equilibrium deviation resulted from external shocks, the present findings of higher inefficiency during the crisis are not surprising as in the chaotic financial environment at that time, investors would overreact not only to local news, but also to news originating in the other markets, especially when the news events were adverse.     

The Timing of Opening Trades and Pricing Errors

After demonstrating that a zero investment trading strategy that buys stocks with overnight returns below the market average and sells stocks with overnight returns above the market average earns more than 1% monthly profit, I demonstrate that this profit is greater for stocks that start trading more quickly than for other stocks. These results control for trading costs. The resulting pricing errors are a material portion of stock price volatility and suggest that a quick response to overnight information adds non‐information‐based stock volatility to stock prices.     

A closer look at return predictability of the US stock market: evidence from new panel variance ratio tests

This paper examines the return predictability of the US stock market using portfolios sorted by size, book-to-market ratio and industry. We use novel panel variance ratio tests, based on the wild bootstrap proposed in this paper, which exhibit desirable size and power properties in small samples. We have found evidence that stock returns have been highly predictable from 1964 to 1996, except for a period leading to the 1987 crash and its aftermath. After 1997, stock returns have been unpredictable overall. At a disaggregated level, we find evidence that large-cap portfolios have been priced more efficiently than small- or medium-cap portfolios; and that the stock returns from high-tech industries are far less predictable than those from non-high-tech industries.     

Sources of fluctuations in hours worked for Canada,Germany, Japan and the U.S.: a sign restriction VAR approach

This study empirically examines the sources of fluctuations in hours worked in Canada, Germany, Japan and the U.S. It is particularly motivated by Galí’s (1999) VAR study, which demonstrates that a positive technology shock reduces hours worked, at least in the short run. However, in the present study, a technology shock is identified without recourse to Galí’s long-run restriction, which has been subject to active controversy. Furthermore, this study uncovers other important sources of fluctuations in hours worked to reflect the concern, raised by numerous studies, that technology shocks leave most variations in hours worked unexplained. Specifically, there are six shocks underlying our model, and they are identified using a set of sign restrictions. The empirical results confirm that in all four countries, a positive technology shock significantly reduces hours worked. This technology shock, along with labor supply and demand shocks, accounts for most of the short-term variations in hours worked. As the forecasting horizon increases, technology and demand shocks become less important, whereas labor supply shocks contribute to explaining the bulk of long-run variations in hours worked. Finally, the empirical relevance of Galí’s long-run identification restriction is tested and the results are related to those obtained using the sign restriction model.
