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.

Financial intermediary leverage and value at risk
We study a contracting model for the determination of leverage and balance sheet size for financial intermediaries that fund their activities through collateralized borrowing. The model gives rise to two features: First, leverage is procyclical in the sense that leverage is high when the balance sheet is large. Second, leverage and balance sheet size are both determined by the riskiness of assets. For U.S. investment banks, we find empirical support for both features of our model, that is, leverage is procyclical, and both leverage and balance sheet size are determined by measured risks. In a ...

Funding liquidity risk and the cross-section of stock returns
We derive equilibrium pricing implications from an intertemporal capital asset pricing model where the tightness of financial intermediaries? funding constraints enters the pricing kernel. We test the resulting factor model in the cross-section of stock returns. Our empirical results show that stocks that hedge against adverse shocks to funding liquidity earn lower average returns. The pricing performance of our three-factor model is surprisingly strong across specifications and test assets, including portfolios sorted by industry, size, book-to-market, momentum, and long-term reversal. ...

How "unconventional" are large-scale asset purchases? The impact of monetary policy on asset prices
This paper examines the impact of large-scale asset purchases (LSAP) on U.S. asset prices (nominal and inflation-indexed bonds, stocks, and U.S. dollar spot exchange rates) using an event study with intraday data. The surprise component of LSAP announcements is identified from Financial Times articles. Estimation results show that the LSAP news has economically large and highly significant effects on asset prices, even after controlling for the surprise component of the Fed's conventional target rate decision and communication about its future path of policy. This study documents that the ...

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 ...
