In this model, labor is introduced in the production function and leisure in the direct utility function. We examine how the trade-off between labor and leisure would affect asset prices and derive a familiar principal partial differential equation which asset prices must satisfy. The solution of this equation gives the equilibrium price of any asset in terms of the underlying real variables in economy.展开更多

After a brief review of the latest literature,this paper analyzes the specific conduction mechanism from different aspects of consumption,investment,credit and exchange rate channels in which asset prices affect inflation. Then,this paper analyzes the monthly data from January,2002 to December,2013 with the PLS method(partial least squares regression method)and discusses whether a structural change has taken place in the inflation mechanism during this period. Finally,policy recommendations are provided.展开更多

By introducing the overreaction coefficient, we provide an explanation for the volatility of asset prices and bubbles in a simplified framework that is similar to the DSSW （1990a） model. When the underlying asset is involved with a fundamental shock, noise traders will generally overreact to it, which creates an ＂overreaction risk＂. This kind of risk will make the asset prices more volatile, and even make up asset bubbles. Therefore, asset bubbles can be regarded as a psychological phenomenon, and are actually the results of the psychological changing process of noise traders.展开更多

Lewellen and Nagel[14] find that the variation in betas and in the equity premium would have to be implausibly large to explain important asset-pricing anomalies. Unfortunately, they do not provide a rigorous test statistic. Based on a simulation study, the method proposed in Lewellen and Nagel[14] tends to reject the null too frequently. We develop a new test procedure and derive its limiting distribution under the null hypothesis. Also, we provide a Bootstrap approach to the testing procedure to gain a good finite sample performance. Both simulations and empirical studies show that our test is necessary for making correct inferences with the conditional CAPM.展开更多

The data set is the panel of 20 most actively traded firms, excluding firms with negative book value of equity. The contribution to the extant literature is three-fold： （l） organizing Saudi market data based on beta and firm-specific fundamentals, namely, growth, value, accounting earnings, and equity investments; （2） conducting a parsimony analysis within the theoretical framework of APT; and （3） quantifying the information risk facing the marginal investor by decomposing earnings into cash flows and accruals and investigating respective loadings in an unrestricted version of the parsimonious specification. Proxy asset pricing specifications, though intuitively appealing, are scant due to lack of theoretical frameworks and misguided significance tests of factor loadings. Throughout, this issue is addressed by keeping the empirical analysis under describing market facts and testing an APT model. The study concludes with a significant empirical explanation that specifies average returns in terms of the covariance risk and accounting accruals.展开更多

The authors use data on five developed countries and five emerging countries as well as data on the Tunis Stock Exchange （TSE） after the reforms. The results show that the correlations between emerging markets returns and developed markets returns are very low and sometimes negative. Conditional arbitrage pricing theory （APT） as well as conditional CAPM has low predictive power for emerging markets than that for developed markets. Finally, following the financial reforms, Tunisian financial markets have became more and more integrated into the international market （excess returns and unconditional beta consistent with predictions）. However, conditional APT does not accurately explain Tunisian market returns. This study confirms the unavailability of an accurate modelling technique of the TSE structure.展开更多

Nowadays, because of world energy price decline, the world energy market is facing weak investment and financing sharply under pressure. Under this background, this paper aims at briefly commenting on the content, processes and impact of mining right asset securitization, understanding the international mining right asset securitization specific practices, and then combining the situation of China(Shanghai) Pilot Free Trade Zone so as to give advice for the development of mining right asset securitization in China. For instance, mineral mining rights and expenses system design are not clear, so the mineral values do not reflect their true costs and the need to speed up market credit system construction.展开更多
