Free cash flow, debt-monitoring and managers' LIFO/FIFO policy choice

This paper explores the explanatory power of Jensen's free cash flow hypothesis in managers' choice of LIFO versus FIFO. The association between FCF, and choice of inventory methods is based on the assumption that there is a potential conflict of interest between managers and shareholders when LIFO is the tax minimization method and that non-value-maximizing managers of firms with the FCF problem have incentives to choose FIFO, an income increasing method, in order to increase their compensation. However, since debt can act as a monitoring device and mitigate the agency problems of FCF, managers of firms with high FCF and high debt are less likely to choose FIFO than managers of firms with high FCF and low debt. The evidence is consistent with this expectation.

Ecological integrity as an economic variable: An application to forested landscapes in the southern United States

Ecological integrity is important to fully describe the development of an economy. We calculated an aggregate index that quantifies the closeness of a forested region to a natural state. This naturalness index was based on the diversity of native tree species and sizes for ecological subregions in a seral condition. The index used the spatial–temporal array of sample plots from the Forest Inventory and Analysis (FIA) database of the USDA Forest Service. In the 70 survey units of the southern US between 1961 and 2005 the naturalness of forests generally improved with per capita personal income and population. The increase with income was consistent with the hypothesis of an environmental Kuznets curve for forested landscapes.     

Dynamic Panel Data Evidence on the Trade-Income Relation

This paper revisits the relationship between a country’s openness and its per capita income. Building on Frankel and Romer, it argues that a dynamic econometric specification similar to the ones used in empirical growth studies better fits the theoretical literature and also resolves some otherwise unresolved inconsistencies. The preferred econometric method is Blundell and Bond’s system-GMM estimator, which allows dealing with measurement error, weak instruments, and time-invariant country-specific effects. The findings confirm the existence of a strong effect of trade on income but fail to find evidence for trade as an independent factor of divergence. JEL no. F43, O40     

Emerging markets, evolving institutions, and the new opportunities for growth in China's rural economy

In this essay, our goal is to assess the state of China's rural economy and examine whether rural China is capable of participating in the sequence of economic events that will lead to modernization. We examine how agricultural productivity has changed, the nature of the shift of labor moving from rural to urban areas, how commodity markets have evolved, and how the rural industrial sector is adjusting the recent reforms. According to our own work and that of others, we show how the rural economy is beginning to be fundamentally transformed and is contributing to China's modernization.     

Tolerance for uncertainty and the growth of informationally opaque industries

Hofstede's [Hofstede, Geert H. 1980. Culture's consequences: international differences in work-related values. Thousand Oaks, CA: Sage.] cross-country psychological survey of IBM employees finds that some countries (societies) are systematically less tolerant of uncertainty, while uncertainty-tolerance is shown by some theoretic models to be essential to the growth of emerging sectors about which less is known. This paper first uses Durnev, Morck, and Yeung's [Durnev, Art, Morck, Randall, and Yeung, Bernard. 2004. Value-enhancing capital budgeting and firm-specific stock return variation. The Journal of Finance. 59(1): 65–105.] methodology to identify these informationally opaque industries. The hypothesis is then made that countries characterized by high uncertainty aversion (measured by Hofstede's indicator, and two other alternative indicators) will grow disproportionately slower in industrial sectors where information is less available. Using the Rajan and Zingales [Rajan, Raghuram G. and Zingales, Luigi. 1998. Financial Dependence and Growth. American Economic Review. Vol. 88(3): 559–586.] “difference-in-differences” methodology, which is relatively free from the endogeneity problem, the study provides robust evidence of such an industrial growth pattern in 34 countries and 36 manufacturing industries. It also shows that national uncertainty aversion is not driven by underdevelopment of financial sector, inadaptability of civil law systems, lower level of economic or human capital development, labor market inflexibility, or any of many other institutional factors. The results remain robust when religious (Catholic vs. Protestant) composition is used as an instrumental variable for national uncertainty aversion. The international evidence presented helps explain why some countries are slower in embracing “new” (vs. traditional) industries.

贸易开放度与中国经济增长关系的地区差异研究

为了探求中国的开放政策是否促进了经济增长，以及开放政策对不同区域的作用是否存在差异，本文在相关文献回顾的基础上，运用中国大陆地区28个省、自治区和直辖市（海南、重庆、西藏除外）1984-2004年的相关数据，采用Panel Data模型对贸易开放度与中国经济增长的关系问题进行了实证研究。研究的结论认为开放的对外经济贸易政策促进了中国的经济增长；井且通过研究发现这一促进作用存在着地区差异，对于中西部地区来说，促进作用更大。
