We show that collateral constraints restrict firm entry and post-entry growth, using French administrative data and cross-sectional variation in local house-price appreciation as shocks to collateral values. We control for local demand shocks by comparing treated homeowners to controls in the same region that do not experience collateral shocks: renters, and homeowners with an outstanding mortgage, who (in France) cannot take out a second mortgage. In both comparisons, an increase in collateral value leads to a higher probability of becoming an entrepreneur. Conditional on entry, treated entrepreneurs use more debt, start larger firms, and remain larger in the long run. This article is protected by copyright. All rights reserved

This paper examines the extent to which individual investors provide liquidity to the stock market, and whether they are compensated for doing so. We show that the ability of aggregate retail order imbalances, contrarian in nature, to predict short-term future returns is significantly enhanced during times of market stress, when market liquidity provisions decline. While a weekly rebalanced portfolio long in stocks purchased and short in stocks sold by retail investors delivers 19% annualized excess returns over a four factor model from 2002 to 2010, in periods of high uncertainty it delivers up to 40% annualized returns. Despite this high aggregate performance, individual investors do not reap the rewards from liquidity provision because (i) they experience a negative return on the day of their trade, and (ii) they reverse their trades long after the excess returns from liquidity provision are dissipated. Finally, we show that experienced traders tend to do better on both dimensions.

This paper shows that collateral constraints restrict entrepreneurial activity. Our empirical strategy uses variations in local house prices as shocks to the value of collateral available to individuals owning a house and controls for local demand shocks by comparing entrepreneurial activity of homeowners and renters operating in the same region. We find that an increase in collateral value leads to a higher probability of becoming an entrepreneur. Conditional on entry, entrepreneurs with access to more valuable collateral create larger firms and more value added, and are more likely to survive, even in the long run.

We show that banks' exposure to interest rate risk, or income gap, plays a crucial role in monetary policy transmission. While banks have, on average, positive levels of income gap - their assets are more sensitive to interest rate changes than their liabilities - there is substantial heterogeneity in the cross-section of banks in how exposed they are to interest rate risk. In a first step, we show that the sensitivity of bank profits to interest rates increases significantly with their income gap, even when banks use interest rate derivatives. In a second step, we show that the income gap also predicts the sensitivity of bank lending to interest rates, both for commercial & industrial loans and for mortgages. Quantitatively, a 100 basis point increase in the Fed funds rate leads a bank at the 75th percentile of the income gap distribution to increase lending by about 1.6 percentage points annually relative to a bank at the 25th percentile. We conclude that banks' exposure to interest rate risk is an important determinant of the lending channel.
