中国失衡时代是否已终结

过去十年,全球性不均衡问题逐渐成为各国宏观经济政策的中心议题。本文重点分析了当前中国的外部失衡问题,研究了2008年后促使中国经常账户盈余下降的影响因素,预测了中国外部顺差的走向。本文认为,未来几年中国的经常账户盈余将保持适度。外部失衡不能反映当今中国国际收支的主要特征。随着中国国内经济越来越依赖投资的拉动,内部失衡问题将愈发明显。     

Sudden stops, banking crises and investment collapses in emerging markets

We evaluate whether financial openness leaves emerging market economies vulnerable to the adverse effects of capital reversals (“sudden stops”) on domestic investment. We investigate this claim in a broad sample of emerging markets during the period 1976–2002. If the banking sector does not experience a systemic crisis, sudden stop events fail to have a significant impact on investment. Bank crises, on the other hand, have a significant negative effect on investment even in the absence of a contemporaneous sudden stop crisis. We also find that openness to capital flows worsens the adverse impact of banking crises on investment. Our results provide statistical support for the policy view that a strong banking sector which can withstand the negative fallout of capital flight is essential for countries that open their economies to international financial flows.     

Loan Loss Provisions by Banks in Hong Kong, Malaysia and Singapore

This paper studies loan loss disclosures by banks in Hong Kong, Malaysia, and Singapore for the period 1993 through 2000. We find that unexpected loan loss provisions are positively related to bank stock returns and future cash flows. This indicates that Asian bank managers increase loan loss provisions to signal favorable cash flow prospects, and bank investors bid bank stock prices up when unexpected provisions are positive. These results are consistent with those obtained by Wahlen (1994) for US banks. We also examine the impact of the Asian financial crisis of 1997 on the loan loss variables. The results indicate that the association between the unexpected loan loss provisions and bank stock returns and future cash flows was significantly lower in the crisis years, relative to the non‐crisis period. Evidently, discretionary loan loss provisions had no signaling value during the crisis. This suggests that macroeconomic uncertainty influenced the strategic behavior of Asian bank managers and investors.     

The Predictive Value of Earnings, Cash flows and Accruals in the Period Surrounding the Asian Financial Crisis: Evidence from Hong Kong, Malaysia, Singapore and Thailand

This paper examines the predictive value of earnings, operating cash flows and accruals in Hong Kong, Malaysia, Singapore and Thailand for the period 1994–2001. We also examine the impact of the Asian financial crisis of 1997 on the predictive power of the accounting performance measures. We regress future cash flows and future excess returns on earnings (or cash flows and accruals) for the periods 1994–1996 (pre‐crisis period), 1997–1998 (crisis period) and 1999–2001 (post‐crisis period). Our findings indicate that the accounting measures have explanatory power for 1‐year ahead cash flows. Our analyses of 1‐year ahead excess returns indicate that investors may have undervalued the accounting measures in the pre‐ and post‐crisis periods, and overvalued the measures during the crisis period.     

The impact of regulation FD on the information environment: evidence from the stock market response to stock split announcements

This paper examines the information environment effects of regulation fair disclosure (Reg FD). We investigate the stock market response to stock splits in the pre- and post-regulation periods. We find that abnormal returns around split announcement are positive in both periods, but the magnitude of the returns is smaller in the post-FD period relative to the pre-FD period. The difference between the pre- and post-FD period abnormal returns persists even after we control for factors that may affect split announcement returns. We also find that the magnitude of the association between announcement returns and the unexpected portion of the split factor has increased post-regulation. Our analysis of performance trends for split firms reveals that patterns of profitability and changes in profitability in the years around stock splits are similar in the pre- and post-FD periods. However, we find that announcement returns are associated with lagged profitability changes in the pre-FD period, but with future profitability changes in the post-FD period. Collectively, our results imply that Reg FD has reduced information asymmetry and improved price efficiency.     

An End to China's Imbalances?

As early as 2005,analysts and academics became concerned about the prospects for,and sustainability of,growing current account imbalances in the world's largest economies.In the United States,low savings rates and growing household consumption,fueled in part by what later turned out to be a bubble in the property market,sucked in imports from abroad,causing the trade and current account deficit to balloon.Of course,this deficit had a counterpart among the United States' principal trading partners.     

Macroeconomic effects of aggregate accounting conservatism: A cross‐country analysis

This paper examines whether aggregate conditional and unconditional conservatism are associated with economic growth. Prior studies find that conditional conservatism improves contracting efficiency, but that unconditional conservatism has either a neutral or detrimental impact on contracting. We therefore conjecture that country‐level conditional conservatism increases the efficiency of resource allocation in an economy, whereas country‐level unconditional conservatism is not similarly beneficial. Using a cross‐country sample, we construct country‐level estimates of conditional and unconditional conservatism. We find that conditional conservatism is associated with higher level of growth in Gross Domestic Product and Gross Domestic Product per Capita. By contrast, unconditional conservatism shows no or negative association. Our study contributes to the ongoing debate on the desirability of accounting conservatism and also extends the literature on the macroeconomic effects of aggregate financial reporting attributes.     

Bankruptcy probability changes and the differential informativeness of bond upgrades and downgrades

Prior studies have found that stock returns around announcements of bond upgrades are insignificant, but that stock prices respond negatively to announcements of bond downgrades. This asymmetric stock market reaction suggests either that bond downgrades are timelier than upgrades, or that voluntary disclosures by managers preempt upgrades but not downgrades. This study investigates these conjectures by examining changes in firms’ probabilities of bankruptcy (assessed using bankruptcy prediction models) and voluntary disclosure activity around rating change announcements. The results indicate that the assessed probability of bankruptcy decreases before bond upgrades, but not after. By contrast, the assessed probability of bankruptcy increases both before and after bond downgrades. We also find that controlling for potential wealth-transfer related rating actions, which can impact stock returns differently, does not alter our results. Tests of press releases and earnings forecasts issued by firms suggest that the differential informativeness of upgrades and downgrades is not caused by differences in pre-rating change voluntary disclosures by upgraded and downgraded firms. The results support the hypothesis that downgrades are timelier than upgrades.
