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 ...

Foreign exchange volatility is priced in equities
This paper finds that standard asset pricing models fail to explain the significantly positive delta hedging errors from writing options on foreign exchange futures. Foreign exchange volatility does influence stock returns, however. The volatility of the JPY/USD exchange rate predicts the time series of stock returns and is priced in the cross-section of stock returns. Foreign exchange volatility risk might be priced because of its relation to foreign exchange level risk. ; Earlier title: Is foreign exchange delta hedging risk priced?

Pessimistic beliefs under rational learning: quantitative implications for the equity premium puzzle
In the presence of infrequent but observable structural breaks, we show that a model in which the representative agent is on a rational learning path concerning the real consumption growth process can generate high equity premia and low risk-free interest rates. In fact, when the model is calibrated to U.S. consumption growth data, average risk premia and bond yields similar to those displayed by post- depression (1938-1999) U.S. historical experience are generated for low levels of risk aversion. Even ruling out pessimistic beliefs, recursive learning inflates the equity premium without ...

Optimal portfolio choice under regime switching, skew and kurtosis preferences
This paper proposes a new tractable approach to solving multi-period asset allocation problems. We assume that investor preferences are defined over moments of the terminal wealth distribution such as its skew and kurtosis. Time-variations in investment opportunities are driven by a regime switching process that can capture bull and bear states. We develop analytical methods that only require solving a small set of difference equations and thus are very convenient to use. These methods are applied to a simple portfolio selection problem involving choosing between a stock index and a risk-free ...

Size and value anomalies under regime shifts
This paper finds strong evidence of time-variations in the joint distribution of returns on a stock market portfolio and portfolios tracking size- and value effects. Mean returns, volatilities and correlations between these equity portfolios are found to be driven by underlying regimes that introduce short-run market timing opportunities for investors. The magnitude of the premia on the size and value portfolios and their hedging properties are found to vary significantly across regimes. Regimes are also found to have a large impact on the optimal asset allocation - especially under ...

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 ...

Properties of equilibrium asset prices under alternative learning schemes
This paper characterizes equilibrium asset prices under adaptive, rational and Bayesian learning schemes in a model where dividends evolve on a binomial lattice. The properties of equilibrium stock and bond prices under learning are shown to differ significantly compared with prices under full information rational expectations. Learning causes the discount factor and risk-neutral probability measure to become path-dependent and introduces serial correlation and volatility clustering in stock returns. We also derive conditions under which the expected value and volatility of stock prices will ...
