论股权配给作用于宏观经济波动的机理

当宏观经济进入衰退阶段时,由于融资企业的股权配给,融资企业投资的边际破产成本上升,这将导致融资企业的投资下降,在投资乘数原理和加速数原理的相互作用下,会使宏观经济衰退更加严重,宏观经济陷入经济衰退与股权配给相互作用的恶性循环中,宏观经济衰退的程度会进一步加大。当宏观经济进入繁荣阶段时,具有与上述相类似的过程,会导致宏观经济持续过度繁荣。因此,股权配给是宏观经济波动的加速器。我国的现实是,从微观上看,上市公司具有强烈的股权融资偏好;从宏观上看,政府进行股权配给。两者的共同作用,使股权配给具有平抑宏观经济波动的功能。

Do executive stock option grants have value implications for firm performance?

Consistent with predictions of agency theory, we find direct evidence that executive stock option grants have value implications for firm performance. This inference is drawn from evaluation of various motivations for the use of such grants in executive compensation: value enhancement, risk taking, tax benefit, signaling and cash conservation. We find consistent evidence for the value enhancement motivation to reduce agency costs. As well, they signal for positive price sensitive information. Our results reject the tax benefit and cash conservation motivations. This finding is robust after controlling for the endogenous character of executive stock option grants and other equity-based grants. JEL Classification G32 • J33 • M52     

印花税调整对股票价格影响的实证研究

印花税下调在短期内对大盘股指产生显著影响,但这种影响随时间的推移而逐渐减弱;税率下调对沪市和深市单只股票具有冲击效应,个股产生正的超额收益;税率下调对两市的大盘波动性产生显著影响,刺激了"噪声交易者",在短期内产生了噪声效应。目前印花税仍然存在一些不足,建议:拓宽税基,改双向征税为单向征税,尽快开征股票交易税。

Reflections on the Efficient Market Hypothesis: 30 Years Later

In recent years financial economists have increasingly questioned the efficient market hypothesis. But surely if market prices were often irrational and if market returns were as predictable as some critics have claimed, then professionally managed investment funds should easily be able to outdistance a passive index fund. This paper shows that professional investment managers, both in The U.S. and abroad, do not outperform their index benchmarks and provides evidence that by and large market prices do seem to reflect all available information.     

The Credit Channel at the Zero Lower Bound through the Lens of Equity Prices

This study examines the impact of unconventional monetary policies on the stock market when the short‐term nominal interest rate is stuck at the zero lower bound (ZLB). Unconventional monetary policies appear to have significant effects on stock prices and the effects differ across stocks. In agreement with existing credit channel theories, I find that firms subject to financial constraints react more strongly to unconventional monetary policy shocks [especially large‐scale asset purchases (LSAPs)] than do less constrained firms. These results imply that the credit channel is as important as the interest rate channel in the transmission of unconventional monetary policies at the ZLB.
