1. China’s Model of Managing the Financial System
Abstract:
China’s economic model involves active government intervention in financial markets. We develop a theoretical framework in which interventions prevent a market breakdown and a volatility explosion caused by the reluctance of short-term investors to trade against noise traders. In the presence of information frictions, the government can alter market dynamics since the noise in its intervention program becomes an additional factor driving asset prices. More importantly, this may divert investor attention away from fundamentals and totally toward government interventions (as a result of complementarity in investors’ information acquisition). A trade-off arises: government’s objective to reduce asset price volatility may worsen, rather than improve, information efficiency of asset prices.
中國金融體系管理模式
中國金融體系的特點之一是政府通過對金融體系的積極干預以維持金融穩定。由于中國的金融市場存在大量缺乏經驗的“散戶”(即噪音交易者),具有高度的投機性,容易造成短期市場波動。而針對這些市場波動,政府進行有效的干預,有助于減少市場波動并確保金融穩定。然而,政府干預能否保證金融體系的信息效率?本研究構建了一個理論模型來分析政府干預的效果,在模型中政府直接與噪音交易者進行交易。模型分析表明,更密集的干預雖然可以降低資產價格的波動,但同時也可能降低市場的信息效率。在信息摩擦的環境下,政府干預會導入自身的噪音,而成為新的市場因子,并分散投資人的注意力。當投資人把有限的注意力放在分析政府干預的噪音因子上而不是市場基本面時,政府干預會降低而不是提高市場的信息效率。

2. The Whack-A-Mole Game: Tobin Taxes and Trading Frenzy
Abstract:
To dampen trading frenzy in the stock market, the Chinese government tripled the stamp tax for stock trading on May 30, 2007. The greatly increased trading cost triggered a migration of the trading frenzy from the stock market to the warrant market—which was not subject to the stamp tax—exacerbating a price bubble in the warrant market. Investor account data uncover not only large inflows of new investors to the warrant market but also greatly intensified trading by existing warrant investors. This episode exemplifies the so-called “whack-a-mole” game in financial regulations.
“打地鼠”游戲:托賓稅和交易狂熱
為平抑股市的交易狂熱,中國政府于2007年5月30日將股票交易印花稅提高了兩倍。此舉使交易成本大幅增加,促使大量交易從股票市場轉移到不受印花稅影響的權證市場,從而加劇了權證市場的價格泡沫。投資者賬戶數據顯示,大量新投資者涌入權證市場,現有權證投資者的交易也大幅增加。這一事件例證了金融監管中所謂的“打地鼠”現象。

3. Learning about the Neighborhood
Abstract:
We develop a model to analyze information aggregation and learning in housing markets. Households enter a neighborhood by buying houses and consuming each other’s final goods. In the presence of pervasive informational frictions, housing prices serve as important signals to households and capital producers about the neighborhood’s economic strength. Our model provides a novel amplification mechanism in which noise from housing markets propagates throughout the local economy via learning because of the complementarity in households’ decisions, distorting migration into the neighborhood and the supply of capital and labor. We provide consistent evidence based on the recent U.S. housing cycle.
從房價了解社區信息
在信息摩擦普遍存在的情況下,房價成為了家庭和投資者了解社區經濟實力的重要信號。本研究構建了分析住房市場中信息聚集和信息獲取的模型,提供了一種全新的放大機制。由于家庭決策的互補性,住房市場中的噪聲通過信息獲取在當地傳播,對經濟產生影響,干擾社區的人口遷移以及資本和勞動力的供給。對美國近期的住房周期的分析為這一觀點提供了一致證據。
