Using a neoclassical growth model augmented with human capital, we investigate the impact of the presence of state owned enterprises
(SOEs) on macroeconomic performance in China, using provincial data from 1990 to 2004. We estimate a macroeconomic model with
panel methods to explain changes in labor productivity resulting from standard influences as well as presence of the SOE sector
measured in five different ways. While controlling for growth in the labor force and physical capital, government size, exposure
to trade and change in economic structure, we conclude that the relative share of the SOE sector has no significant influence
on macroeconomic performance in China during our sample period. 相似文献

Coronary artery vasculitis is a well-recognized complication of polyarteritis nodosa and is occasionally seen in other forms of systemic vasculitis. However, involvement of the major epicardial coronary arteries leading to myocardial infarction and death is uncommon. Isolated coronary arteritis is even more rare. We report three cases of sudden death due to myocardial ischemia associated with arteritis of the major coronary arteries. All three decedents were previously healthy young to middle-aged men who had died suddenly after complaints of chest pain and shortness of breath. The autopsy findings and differential diagnoses are presented. Such cases are of particular interest to the medical examiner because of the sudden, unexpected nature of the deaths. An approach to the correct diagnosis is discussed. 相似文献

By using a dynamic stochastic optimization model, this paper shows that the existence of punishment does not necessarily deter
extramarital affairs. This study may help to explain why extramarital affairs are a common phenomenon in most societies even
though punishment exists. This study also has an implication for family laws: extramarital affairs can be effectively reduced
if the legal punishment scheme is designed in the way that makes the adulterer’s expected loss increase with the level of
adultery at an increasing or constant rate.
