Abstract:Data from China’s credit crunch, which started in 2007, is utilized to establish a natural experiment to investigate the impact of the credit crunch on target capital structures. The sample consists of 1,128 listed companies in China during the period 2000–2011. The interest-bearing debt to total assets ratio is used as a representative indicator for capital structures. The results indicate that the credit crunch was associated with a decrease in the target debt ratios for all listed companies. Small firms, privately owned enterprises, and firms with weak mortgage capabilities responded more sensitively to the credit crunch by showing a substantial decrease in target debt ratios. 相似文献

Discretionary current accruals of Chinese initial public offering (IPO) firms decreased after the abolition of fixed‐price offering systems that directly linked offering price to reported earnings. Results suggest IPO firms that decrease managerial ownership manage earnings upward during the fixed‐price offering period, but this relationship disappeared after the introduction of a book‐building system. We also find that bank debt is negatively related to discretionary current accruals during the fixed‐price offering period, but no relation exists for the book‐building period. Leverage has a significant positive relationship with earnings management. However, this finding is potentially attributable to nonoffering price objectives or endogeneity biases. 相似文献

Public–private partnerships (PPP) have been widely used in China to procure public facilities and services. Complicated problems in PPP projects in China arise because of a variety of risk factors. A proper risk assessment model is needed to identify risks and provide risk response strategies for future Chinese PPP projects. The fuzzy analytic hierarchy process (F-AHP) method provides the ability to solve complex risk assessment of PPP projects. Current risk assessment models are limited to PPP projects in specific countries and do not consider unique risks in China, especially political, economic, social, and legal risks. This paper designed a risk evaluation index system for PPP projects based on the Delphi expert investigation method, and then established an optimized risk evaluation model for PPP projects in China using the F-AHP method. The risks identified are confirmed by interviewing experts from Chinese local government departments, private enterprise, third-party intermediary consulting and regulatory agencies, and academic organizations. The results show that the risks that ranked among the top ten are closely related to China’s political and economic policies and relationships among stakeholders. It can be concluded that government authorities play a critical role in providing a favorable political, social, and economic environment and an effective institutional framework for PPP projects. Furthermore, it is also important to deal with relationships among stakeholders based on the public–private ‘win–win’ principle. This study provides risk response strategies, addressing key issues from eight aspects: an impeccable legal and regulatory framework; a central coordinating and regulating PPP authority; supportive governmental authorities; institutional capacity-building; favorable economic conditions and viability; community, partner, and moral accountability; clear division of responsibilities through contracts; and effective advisory management. These effective measures may be useful in reducing the adverse effects of risk for PPP projects in China. 相似文献

Natural resources influence economic performance through many different mechanisms, both beneficial and harmful. Some of these mechanisms tend to set in fast while others are rather slow. This suggests that pooling the long- and short-run effect as typical in the resource empirical literature may lead to incorrect inferences. This article provides an evaluation of the income contribution of natural resources using a panel cointegration approach that allows for short-run dynamic heterogeneity while imposing the restriction of long-run homogeneity. It finds, in a sample of developing countries over the period 1990–2012, that natural resources are a curse in the long run. The evidence is robust to alternative dynamic specifications, different measures and types of natural resource wealth, and controlling for regional effects. 相似文献

Over the past decade, China’s outward foreign direct investment (OFDI) has rapidly increased. However, its characteristics are not sufficiently studied. In this article, we explore the host country’s determinants of China’s OFDI, with a focus on institutional quality, exchange rate volatility, and natural resources by performing an econometric analysis for the period 2003–2013 for a sample of 49 countries. Our results reveal that China’s OFDI is invested in countries with relatively poor institutional quality and abundant natural resources. Exchange rate variability has a dampening effect on China’s OFDI and that the appreciation of the Chinese renminbi enhances OFDI flows. 相似文献

Option pricing based on hybrid GARCH-type models with improved ensemble empirical mode decomposition
The exploration of option pricing is of great significance to risk management and investments. One important challenge to existing research is how to describe the underlying asset price process and fluctuation features accurately. Considering the benefits of ensemble empirical mode decomposition (EEMD) in depicting the fluctuation features of financial time series, we construct an option pricing model based on the new hybrid generalized autoregressive conditional heteroskedastic (hybrid GARCH)-type functions with improved EEMD by decomposing the original return series into the high frequency, low frequency and trend terms. Using the locally risk-neutral valuation relationship (LRNVR), we obtain an equivalent martingale measure and option prices with different maturities based on Monte Carlo simulations. The empirical results indicate that this novel model can substantially capture volatility features and it performs much better than the M-GARCH and Black–Scholes models. In particular, the decomposition is consistently helpful in reducing option pricing errors, thereby proving the innovativeness and effectiveness of the hybrid GARCH option pricing model. 相似文献
