We investigate the development of an innovative and high-risk type of borrowing for local governments, known as structured loans. Using transaction data for more than 2,700 local governments in France, we show that the adoption of these instruments is more frequent for politicians from highly indebted local governments, from politically contested areas, and during political campaigns. Taking on structured loans helps incumbents win a reelection, and initially allows them to maintain lower taxes. Our findings illustrate how financial innovation can amplify principal-agent problems within the political system

We study whether relationship lending is conducive to the financing of innovation. Exploiting a negative shock to relationships, we show that it reduces the number of innovative firms, especially those that depend more on relationship lending such as small, young, and opaque firms. This credit supply shock leads to reallocation of inventors whereby young and promising inventors leave small firms and move out of geographical areas where lending relationships are hurt. Overall, our results suggest that credit markets affect both the level of innovation activity and the distribution of innovative human capital across the econom

Toxic Arbitrage

Short-lived arbitrage opportunities arise when prices adjust with a lag to new information. They are toxic because they expose dealers to the risk of trading at stale quotes. Hence, theory implies that more frequent toxic arbitrage opportunities and faster responses to these opportunities should impair liquidity. We provide supporting evidence using data on triangular arbitrage. As predicted, illiquidity is higher on days when the fraction of toxic arbitrage opportunities and arbitrageurs’ relative speed are higher. Overall, our findings suggest that the price efficiency gain of high-frequency arbitrage comes at the cost of increased adverse selection risk

We review the extensive literature on systemic risk and connect it to the current regulatory debate. While we take stock of the achievements of this rapidly growing field, we identify a gap between two main approaches. The first one studies different sources of systemic risk in isolation, uses confidential data, and inspires targeted but complex regulatory tools. The second approach uses market data to produce global measures which are not directly connected to any particular theory, but could support a more efficient regulation. Bridging this gap will require encompassing theoretical models and improved data disclosure

Ambiguity Aversion and Household Choice Puzzles: Empirical Evidence

We test the relation between ambiguity aversion and five household portfolio choice puz- zles: nonparticipation in equities, low allocations to equity, home-bias, own-company stock ownership, and portfolio under-diversification. In a representative US household survey, we measure ambiguity preferences using custom-designed questions based on Ellsberg urns. As theory predicts, ambiguity aversion is negatively associated with stock market partic- ipation, the fraction of financial assets in stocks, and foreign stock ownership, but it is positively related to own-company stock ownership. Conditional on stock ownership, am- biguity aversion is related to portfolio under-diversification, and during the financial crisis, ambiguity-averse respondents were more likely to sell stocks

Are retail traders compensated for providing liquidity?

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, it delivers up to 40% annualized returns in periods of high uncertainty. Despite this high aggregate performance, individual investors do not reap the rewards from liquidity provision because they experience a negative return on the day of their trade and they reverse their trades long after the excess returns from liquidity provision are dissipated. During the financial crisis, French active retail stock traders stepped up to the plate,increased stock holdings, and provided liquidity. In contrast, mutual fund investors fled from delegation by selling their mutual funds

Debt decisions in deregulated industries

Deregulation significantly affects firms’ debt decisions. Prior to deregulation, regulated firms depend more on long-term and public debt but reduce this dependence considerably during deregulation. Cross-sectional analysis shows that the lower use of long-term and public debt results from changing firm sensitivities to determinants of debt decisions triggered by deregulation. Consistent with credit and liquidity risk theories of debt maturity, the concave relation between firm quality and debt maturity is attenuated among regulated firms. Inconsistent with these theories, the convex relation between firm quality and public debt issues exists only among regulated firms. I find limited support for other theories

Fed Funds Futures Variance Futures

Mots clés : fed funds futures, Funding costs, Unsecured interbank money market


We develop a novel contract design, the fed funds futures (FFF) variance futures, which reflects the expected realized basis point variance of an underlying FFF rate. The valuation of short-term FFF variance futures is completely model-independent in a general setting that includes the cases where the underlying FFF rate exhibits jumps and where the realized variance is computed by sampling the FFF rate discretely. The valuation of longer-term FFF variance futures is subject to an approximation error which we quantify and show is negligible. We also provide an illustrative example of the practical valuation and use of the FFF variance futures contract

Information asymmetry, the cost of debt, and credit events: Evidence from quasi-random analyst disappearances

We hypothesize that greater information asymmetry causes greater losses to debtholders. To test this, we identify exogenous increases in information asymmetry using the loss of an analyst that results from broker closures and broker mergers. We find that the loss of an analyst causes the cost of debt to increase by 25 basis points for treatment firms compared to control firms, and the rate of credit events (e.g., defaults) is roughly 100–150% higher. These results are driven by firms that are more sensitive to changes in information (e.g., less analyst coverage). The evidence is broadly consistent with both financing and monitoring channels, although only a financing channel explains the impact of the loss of an analyst on firms' cost of debt

This article examines whether firm-level idiosyncratic shocks propagate in production networks. We identify idiosyncratic shocks with the occurrence of natural disasters. We find that affected suppliers impose substantial output losses on their customers, especially when they produce specific inputs. These output losses translate into significant market value losses, and they spill over to other suppliers. Our point estimates are economically large, suggesting that input specificity is an important determinant of the propagation of idiosyncratic shocks in the economy
