Catching Falling Knives: Speculating on Liquidity Shocks

Many market participants invest resources to acquire information about liquidity rather than fundamentals. I show that agents using such information can reduce the magnitude of short-lived pricing errors by trading against liquidity shocks. However, the short-run stabilizing effect of this behavior also makes it more difficult to identify liquidity shocks, a signal-jamming effect that slows down price discovery in the long run. As more agents invest in nonfundamental information, market prices become more resilient to liquidity shocks but also recover more slowly from temporary price deviations.

We present CoMargin, a new methodology to estimate collateral requirements in derivatives central counterparties (CCPs). CoMargin depends on both the tail risk of a given market participant and its interdependence with other participants. Our approach internalizes trading externalities and enhances the stability of CCPs, thus, reducing systemic risk concerns. We assess our methodology using proprietary data from the Canadian Derivatives Clearing Corporation that includes daily observations of the actual trading positions of all of its members from 2003 to 2011. We show that CoMargin outperforms existing margining systems by stabilizing the probability and minimizing the shortfall of simultaneous margin-exceeding losses

We use the introduction of a financial transaction tax (FTT) in France in 2012 to test competing theories on the impact of FTTs. We find no support for the idea that an FTT improves market quality by affecting the composition of trading volume. Instead, our results are in line with the idea that a lower trading volume reduces liquidity, and thereby market quality. Consistent with theories of asset pricing under transaction costs, we document a shift in security holdings from short-term to long-term institutional investors. More generally, our findings confirm that moderate aggregate effects on market quality can mask large adjustments made by individual market participants

Financing Investment: The Choice between Bonds and Bank Loans

We build a model of investment and financing decisions to study the choice between bonds and bank loans in a firm's marginal financing decision and its effects on corporate investment. We show that firms with more growth options, higher bargaining power in default, operating in more competitive product markets, and facing lower credit supply are more likely to issue bonds. We also demonstrate that, by changing the cost of financing, these characteristics affect the timing of investment. We test these predictions using a sample of U.S. firms and present new evidence that supports our theory
