Monetary policy implementation: common goals but different practices
While the goals that guide monetary policy in different countries are very similar, central banks diverge in their methods of implementing policy. This study of the policy frameworks of four central banks?the Federal Reserve, the European Central Bank, the Bank of England, and the Swiss National Bank?focuses on two notable areas of difference. The first is the choice of an interest rate target, a standard feature of conventional monetary policy. The second is the choice of instruments for managing the central banks? expanded balance sheets?a decision made necessary by the banks? ...

Financial amplification mechanisms and the Federal Reserve's supply of liquidity during the crisis
The small decline in the value of mortgage-related assets relative to the large total losses associated with the financial crisis suggests the presence of financial amplification mechanisms, which allow relatively small shocks to propagate through the financial system. We review the literature on financial amplification mechanisms and discuss the Federal Reserve's interventions during different stages of the crisis in light of this literature. We interpret the Fed's early-stage liquidity programs as working to dampen balance sheet amplifications arising from the positive feedback between ...

Financial intermediation, asset prices, and macroeconomic dynamics
Fluctuations in the aggregate balance sheets of financial intermediaries provide a window on the joint determination of asset prices and macroeconomic aggregates. We document that financial intermediary balance sheets contain strong predictive power for future excess returns on a broad set of equity, corporate, and Treasury bond portfolios. We also show that the same intermediary variables that predict excess returns forecast real economic activity and various measures of inflation. Our findings point to the importance of financing frictions in macroeconomic dynamics and provide quantitative ...

High equity premia and crash fears. Rational foundations
We show that when in Lucas trees model the process for dividends is described by a lattice tree subject to infrequent but observable structural breaks, in equilibrium recursive rational learning may inflate the equity risk premium and reduce the risk-free interest rate for low levels of risk aversion. The key condition for these results to obtain is the presence of sufficient initial pessimism. The relevance of these findings is magnified by the fact that under full information our artificial economy cannot generate asset returns matching the empirical evidence for any positive relative risk ...

Financial amplification of foreign exchange risk premia
Theories of systemic risk suggest that financial intermediaries? balance-sheet constraints amplify fundamental shocks. We provide supporting evidence for such theories by decomposing the U.S. dollar risk premium into components associated with macroeconomic fundamentals and a component associated with financial intermediaries? balance sheets. Relative to the benchmark model with only macroeconomic state variables, balance sheets amplify the U.S. dollar risk premium. We discuss applications to systemic risk monitoring.

Modelling the MIB30 implied volatility surface. Does market efficiency matter?
We analyze the volatility surface vs. moneyness and time to expiration implied by MIBO options written on the MIB30, the most important Italian stock index. We specify and fit a number of models of the implied volatility surface and find that it has a rich and interesting structure that strongly departs from a constant volatility, Black-Scholes benchmark. This result is robust to alternative econometric approaches, including generalized least squares approaches that take into account both the panel structure of the data and the likely presence of heteroskedasticity and serial correlation in ...

Measuring financial asset return and volatility spillovers, with application to global equity markets
The authors provide a simple and intuitive measure of interdependence of asset returns and/or volatilities. In particular, they formulate and examine precise and separate measures of return spillovers and volatility spillovers. The authors framework facilitates study of both noncrisis and crisis episodes, including trends and bursts in spillovers, and both turn out to be empirically important. In particular, in an analysis of 19 global equity markets from the early 1990s to the present, they find striking evidence of divergent behavior in the dynamics of return spillovers vs. volatility ...

Solving the present crisis and managing the leverage cycle
Yale University professor John Geanakoplos discusses implications of ?the leverage cycle??a phenomenon in which leverage is excessive prior to a financial crisis and unacceptably low during the crisis?for regulatory policy and reform. Presented as the keynote address at "Central Bank Liquidity Tools and Perspectives on Regulatory Reform" a conference sponsored by the Federal Reserve Bank of New York, February 19-20, 2009.
