We study the fragility of discretionary liquidity provision by major financial intermediaries during systemic events. The laboratory of our study is the recent collapse of the auction rate securities (ARS) market. Using a comprehensive dataset constructed from auction reports and intraday transactions data on municipal ARS, we present quantitative evidence that auction dealers acted at their own discretion as "market makers" before the market collapsed. We show that this discretionary liquidity provision greatly affected both net investor demand and auction clearing rates. Importantly, such discretionary liquidity provision is fragile. As auction dealers suffered losses from other financial markets and faced increasing inventory pressure, they stopped making markets. Moreover, the drop in support occurred suddenly, apparently triggered by the unexpected withdrawal of one major broker-dealer.

It is commonly supposed in public and academic discourse that inflation and big government are related. We show that economic theory delivers such a prediction only in special cases. As an empirical matter, inflation is significantly positively related to the size of government mainly when periods of war and peace are compared. We find a weak positive peacetime time series correlation between inflation and the size of government and a negative cross-country correlation of inflation with non-defense spending.
