终极控股股东的盈余管理影响股价同步性的实证研究

以2008—2012年中国沪深两市A股上市公司为研究样本,通过回归分析研究了在中国资本市场发展不完善、股权集中的条件下终极控股股东的盈余管理对公司股价同步性的影响。研究结果表明:终极控股股东有强烈动机影响公司的盈余信息披露,导致噪音信息增多、公司的股价同步性下降,股价同步性更多体现市场噪音量而非信息效率;非国有控股的上市公司通过操纵盈余来影响股价进而影响股价同步性的能力强于国有控股的上市公司。     

The price normalization problem in imperfect competition and the objective of the firm

Summary. General equilibrium models of oligopolistic competition give rise to relative prices only without determining the price level. It is well known that the choice of a numéraire or, more generally, of a normalization rule converting relative prices into absolute prices entails drastic consequences for the resulting set of Nash equilibria when firms are assumed to maximize profits. This is due to the fact that changing the price normalization amounts to altering the objective functions of the firms. Clearly, the objective of a firm must not be based on price normalization rules void of any economic content. In this paper we propose a definition of the objective of a firm, called maximization of shareholders' real wealth, which takes shareholders' demand explicitly into account. This objective depends on relative prices only. Real wealth maxima are shown to exist under certain conditions. Moreover, we consider an oligopolistic market and prove the existence of a Nash equilibrium in which each firm maximizes the real wealth of its shareholders.

The out-of-sample forecasting performance of nonlinear models of regional housing prices in the US

This article provides out-of-sample forecasts of linear and nonlinear models of US and four Census subregions’ housing prices. The forecasts include the traditional point forecasts, but also include interval and density forecasts, of the housing price distributions. The nonlinear smooth-transition autoregressive model outperforms the linear autoregressive model in point forecasts at longer horizons, but the linear autoregressive and nonlinear smooth-transition autoregressive models perform equally at short horizons. In addition, we generally do not find major differences in performance for the interval and density forecasts between the linear and nonlinear models. Finally, in a dynamic 25-step ex-ante and interval forecasting design, we, once again, do not find major differences between the linear and nonlinear models. In sum, we conclude that when forecasting regional housing prices in the United States, generally the additional costs associated with nonlinear forecasts outweigh the benefits for forecasts only a few months into the future.     

不完全合作、非合作博弈的逻辑:企业与行业协会价格串谋行为分析

串谋企业涉及的利益主体主要是企业、行业协会与监管者,频频发生的行业协会参与企业价格串谋实际上是不同利益主体之间博弈的结果.他们之间的博弈是不完全合作、非合作博弈.笔者建立了串谋企业及其行业协会、监管者之间的博弈分析模型,认为影响企业及其行业协会价格串谋概率高低的主要因素是制度安排、串谋成本与监管力度等.     

资源价格及其走势与影响的分析

未来资源价格的大幅上涨态势,对资源产品价格和发展中国家贸易条件、经济安全、经济增长方式转变,价格总水平稳定构成多方面重大影响.应对资源价格上涨成为发展的关键.资源价格是虚拟价格,有多种价格形式和定价方法,因此应对资源价格上涨虽然可以采取多种措施,但最重要的还是价格措施.     

房地产价格变动中的汇率因素分析

在构建了适合中国国情的房地产价格与汇率关系模型的基础上,利用该模型并结合2000年第三季度至2008年第二季度的最新数据,对中国35个城市房地产价格与汇率的关系进行实证研究。研究结果显示,汇率对房地产价格有负影响,这与理论和当前实际情况都比较相符,说明人民币汇率已能发挥一定经济调节的功能。
