房地产价格波动的储蓄效应研究：1997-2008——基于省际面板数据的实证检验

本文利用1997～2008年间的省际面板数据，对房地产价格和居民储蓄之间的关系进行了理论分析和实证检验。理论分析表明，区域和省际间实证结果的差异，主要缘于房价对储蓄特殊的影响机理：被动储蓄效应和结构储蓄效应。此外，房价对储蓄的影响还存在间接储蓄效应，这个效应说明房价在短期对储蓄具有正面影响，在长期对经济发展结构具有负面影响。实证结果显示：在全国范围、中部和西部地区，房价与储蓄存在高度显著的正相关关系，即存在明显的储蓄效应，但东部一些省份的估计结果却显示房价对储蓄的影响不显著。

Cross-subsidization Due to Inframarginal Support in Agriculture: A General Theory and Empirical Evidence

A general theory of cross-subsidization due to inframarginal support is developed. Two sources of output distortion are identified: exit deterrence and extramarginal output. Some firms would not be in business without the subsidy. Cost savings due to declining average costs are always greater than the losses incurred where price equals marginal cost. Moreover, it is theoretically possible for inframarginal subsidies to expand output more than equivalent fully coupled subsidies. Empirical analysis of U.S. dairy subsidies isolates these components of cross-subsidization and finds distortions from inframarginal support to be substantial, with implications for trade negotiations, dispute settlement, and policy formulation.     

International Trade and Accounting Policy Choice: Theory and Canadian Evidence

The accounting policy choice literature has identified many factors which have been shown to be useful in explaining cross-sectional variation in the accounting methods used by public companies. One relationship which has been relatively unexplored in this literature is the potential effect of international trade on accounting choice. This study proposes that international trading activities may create incentives for firms to choose income increasing accounting policies. This proposition was tested by examining the depreciation choices of a sample of Canadian firms. Results suggest that importers were more likely to choose income increasing accounting methods than non-importers, while exporting was not found to be related to this accounting choice. These diverging results may be caused by the declining value of the Canadian dollar (relative to the US dollar), which tends to benefit exporters, but is of detriment to importers.

Trade Credit, Corporate Groups, and the Financing of Belgian Firms

We investigate the role of trade credit as a source of financing. Using a sample of 661 large non-financial Belgian firms for the 1989–1991 period, we find that the amount of trade credit a buyer takes is determined by his need for funds and the internally available funds. Trade credit is primarily used to finance short-term assets. As such, it seems to be an important alternative not only for short-term bank debt but also for long-term financial debt, including intragroup debt. We find no evidence that the amount of trade credit taken is influenced by affiliation with the supplier.     

WTO框架对我国粮食贸易的影响及政策选择

加入WTO后 ,我国将失去对农产品的非关税保护措施 ;对国内农业的支持政策和对农产品的出口鼓励政策也将受到较大限制 ,同时我国粮食市场也会受到一定的冲击。但它有利于我国粮食市场机制改革的进一步完善。为此 ,我国应充分利用WTO规则 ,把粮食作为贸易保护的重点。

Does China＇s Huge External Surplus Imply an Undervalued Renminbi？

A pegged exchange rate regime has been pivotal to China's export-led development strategy. However, its huge trade surpluses and massive build up of international reserves have been matched by large deficits for major trading partners, creating acute policy concerns abroad, especially in the USA. This paper provides a straightforward conceptual framework for interpreting the effect of China's exchange rate policy on its own trade balance and that of trading partners in the context of discrepant economic growth rates. It shows how pegging the exchange rate when output is outstripping expenditure induces China's trade surpluses and counterpart deficits for its trading partners. An important corollary is that given its strictly regulated capital account, China's persistently large surpluses imply a significantly undervalued renminbi, which should gradually become more flexible.
