Learning from History : Volatility and Financial Crises
We study the effects of volatility on financial crises by constructing a cross-country database spanning over 200 years. Volatility is not a significant predictor of crises whereas unusually high and low volatilities are. Low volatility is followed by credit build-ups, indicating that agents take more risk in periods of low financial risk consistent with Minsky hypothesis, and increasing the likelihood of a banking crisis. The impact is stronger when financial markets are more prominent and less regulated. Finally, both high and low volatilities make stock market crises more likely, while ...

Lunch Anyone? Volatility on the Tokyo Stock Exchange around the Lunch Break on May 23, 2013, and Stock Market Circuit Breakers
Stock market circuit breakers halt trading activity on a single stock or an entire exchange if a sudden large price move occurs. Their purpose is to forestall cascading trading activity caused by gaps in liquidity or order errors. Whether circuit breakers achieve this goal is contentious. This post adds to the debate by analyzing intraday price formation on the Tokyo Stock Exchange (TSE) on May 23, 2013?the pinnacle of this past year?s volatility in Japanese stock markets. While no circuit breakers were triggered on the TSE, we focus on trading conditions before and after the daily lunch ...

The Response of Stock Market Volatility to Futures-Based Measures of Monetary Policy Shocks
In this paper, we investigate the dynamic response of stock market volatility to changes in monetary policy. Using a vector autoregressive model, our findings reveal a significant and asymmetric response of stock returns and volatility to monetary policy shocks. Although the increase in the volatility risk premium, futures-trading volume, and leverage appear to contribute to a short-term increase in volatility, the longer-term dynamics of volatility are dominated by monetary policy's effect on fundamentals. The estimation results from a bivariate VAR-GARCH model suggest that the Fed does not ...

The impact of risk cycles on business cycles: a historical view
We investigate the effects of financial risk cycles on business cycles, using a panel spanning 73 countries since 1900. Agents use a Bayesian learning model to form their beliefs on risk. We construct a proxy of these beliefs and show that perceived low risk encourages risk-taking, augmenting growth at the cost of accumulating financial vulnerabilities, and therefore, a reversal in growth follows. The reversal is particularly pronounced when the low-risk environment persists and credit growth is excessive. Global-risk cycles have a stronger effect on growth than local-risk cycles via their ...
