Knowledge that Transforms

This paper documents significantly negative stock price reactions to shareholder-initiated class action lawsuits. We find that shareholders partially anticipate these lawsuits based on lawsuit filings against other firms in the same industry and capitalize part of these losses prior to a lawsuit filing date. We show that the more likely a firm is to be sued, the larger the partial anticipation effect (shareholder losses capitalized prior to a lawsuit filing date) and the smaller the filing date effect (shareholder losses measured on the lawsuit filing date). Our evidence suggests that previous research that typically focuses on the filing date effect understates the magnitude of shareholder losses, and that such an understatement is greater for firms with a higher likelihood of being sued.

This paper examines the intertemporal relation between downside risk and expected stock returns. Value at Risk (VaR), expected shortfall, and tail risk are used as measures of downside risk to determine the existence and significance of a risk-return tradeoff. We find a positive and significant relation between downside risk and the portfolio returns on NYSE/AMEX/Nasdaq stocks. VaR remains a superior measure of risk when compared with the traditional risk measures. These results are robust across different stock market indices, different measures of downside risk, loss probability levels, and after controlling for macroeconomic variables and volatility over different holding periods as originally proposed by Harrison and Zhang (1999).

Using a proprietary database of currency trades, this paper explores the effects of trading gains and losses on risk-taking among large institutional investors. We find that institutional investors, unlike individuals, are not prone to the disposition effect. Instead, institutions aggressively reduce risk following losses and mildly increase risk following gains. This asymmetry is more pronounced later in the calendar year and among older and more experienced funds. We show that such performance dependence is consistent with dynamic loss aversion (Barberis, Huang, and Santos (2001)) and overconfidence. In addition, prior institutional gains and losses have palpable implications for future prices.

This paper takes advantage of the fact that some stocks trade both in domestic and international markets to characterize the degree of international financial integration. The paper argues that the cross-market premium (the ratio between the domestic and the international market price of cross-listed stocks) provides a valuable measure of international financial integration and the effectiveness of capital controls. Using autoregressive (AR) models to estimate convergence speeds and non-linear threshold autoregressive (TAR) models to identify non-arbitrage bands, the paper shows that price deviations across markets are rapidly arbitraged away and bands are narrow, particularly so for liquid stocks. The paper also shows that regulations on cross-border capital flows effectively segment domestic markets. As expected, the effects of both types of capital controls are asymmetric but in the opposite direction: controls on outflows induce positive premia, while controls on inflows generate negative premia. Both vary with the intensity of capital controls.

Using a large panel dataset of Chinese industrial firms, we find that poorly performing SOEs were more likely to redistribute credit to firms with less privileged access to loans via trade credit. While that could be consistent with the efficient redistribution of credit, it is more likely that these SOEs extended trade credit to prop up faltering customers that were in arrears. By contrast, profitable private domestic firms were more likely to extend trade credit than unprofitable ones. Trade credit likely provided a substitute for loans for these firms' customers that were shut out of formal credit markets. As biases in lending become less severe, the allocation of lending became more efficient, and the amount of trade credit extended by private firms declined. Our evidence implies that redistribution of bank loans via trade was not a major contributor to China's explosive growth.

In this study, we examine the effect of pre-trade transparency on market quality using data before and after the introduction of SuperMontage. Our results show that both bid–ask spreads and return volatility declined significantly after the implementation of SuperMontage. In addition, SuperMontage led to significant improvements in the SEC Rule 605 execution quality measures (e.g., faster executions and higher fill rates). Overall, our results indicate that SuperMontage improved market and execution quality on NASDAQ through greater pre-trade transparency and the integrated, more efficient quotation and trading system.

The paper seeks to explain the huge cross country variation in private pension funding, shaped by historical choice made when universal pension systems were created after the Great Depression. According to Perotti and von Thadden [Perotti, E., von Thadden, E.-L., 2006. The political economy of corporate control and labor rents. J. Polit. Econ., 145–175], large inflationary shocks due to war damage devastated middle class savings in some countries in the first half of the XX century. This shaped political preferences over the role of capital markets and social insurance, and contributed to the Great Reversals documented by Rajan and Zingales [Rajan, R.G., Zingales, L., 2003. The great reversals: The politics of financial development in the 20th century. J. Finan. Econ. 69 (1), 5–50]. Wealth distribution shocks are indeed strongly related to private pension funding, as a large shock reduces the stock of private retirement assets by 58% of GDP. While the sample size is limited, the results are robust to other explanations, such as legal origin, original financial development, past and current demographics, religion, electoral voting rules, redistributive politics, national experiences with financial market performance, or other major financial shocks that were not specifically redistributive. Corroborating evidence indicates that such redistributive shocks help explain the cross country variation in social expenditures, state ownership of industry, financial development and employment protection measures as predicted by the political shift hypothesis.

Banks can make suboptimal liquidity choices and gamble for lender of last resort (LOLR) support. Endogenous bailout rents are driven by the need to preserve bankers' incentives under uncertain net worth. In equilibrium, banks can herd in risk management, choosing suboptimal liquidity when they expect others to do so. Optimal liquidity can be restored by quantitative requirements, but such regulation is costly. An LOLR policy incorporating bank capital information can reduce distorting rents and allow for a more efficient solution, but may only be possible in transparent economies.

We investigate whether information sharing among banks has affected credit market performance in the transition countries of Eastern Europe and the former Soviet Union, using a large sample of firm-level data. Our estimates show that information sharing is associated with improved availability and lower cost of credit to firms. This correlation is stronger for opaque firms than transparent ones and stronger in countries with weak legal environments than in those with strong legal environments. In cross-sectional estimates, we control for variation in country-level aggregate variables that may affect credit, by examining the differential impact of information sharing across firm types. In panel estimates, we also control for the presence of unobserved heterogeneity at the firm level, as well as for changes in macroeconomic variables and the legal environment.

We analyze a dynamic microstructure model in which a dealer market (DM) and a crossing network (CN) interact for three informational settings. A key result is that coexistence of trading systems generates systematic patterns in order flow, which depend on the degree of transparency. Further, we study overall welfare, measured by the gains from trade of all agents, and compare it with the maximum overall welfare. The discrepancy between both measures is attributable to two inefficiencies. Due to these inefficiencies, introducing a CN next to a DM, as well as increasing the transparency level, not necessarily produces greater overall welfare.
