Search in asset markets
We investigate how trading frictions in asset markets affect portfolio choices, asset prices and efficiency. We generalize the search-theoretic model of financial intermediation of Duffie, Grleanu and Pedersen (2005) to allow for more general preferences and idiosyncratic shock structure, unrestricted portfolio choices, aggregate uncertainty and entry of dealers. With a fixed measure of dealers, we show that a steady-state equilibrium exists and is unique, and provide a condition on preferences under which a reduction in trading frictions leads to an increase in the price of the asset. We ...

International capital flows
The sharp increase in both gross and net international capital flows over the past two decades has prompted renewed interest in their determinants. Most existing theories of international capital flows are based on one-asset models, which have implications only for net capital flows, not for gross flows. Moreover, because there is no portfolio choice, these models allow no role for capital flows as a result of assets? changing expected returns and risk characteristics. In this paper, we develop a method for solving dynamic stochastic general equilibrium open-economy models with portfolio ...

Portfolio choice over the life-cycle when the stock and labor markets are cointegrated
We study portfolio choice when labor income and dividends are cointegrated. Economically plausible calibrations suggest young investors should take substantial short positions in the stock market. Because of cointegration the young agent's human capital effectively becomes.

Performance maximization of actively managed funds
Ratios that indicate the statistical significance of a fund's alpha typically appraise its performance. A growing literature suggests that even in the absence of any ability to predict returns, holding options positions on the benchmark assets or trading frequently can significantly enhance performance ratios. This paper derives the performance-maximizing strategy--a variant of buy-write--and the least upper bound on such performance enhancement, thereby showing that if common equity indexes are used as benchmarks, the potential performance enhancement from trading frequently is usually ...

Stock market participation, portfolio choice and pensions over the life-cycle
The empirical evidence on stock market participation and portfolio choice defies the predictions of standard life-cycle theory. In this paper we develop and estimate a model of portfolio choice that can account for the limited stock market participation and substantial portfolio diversification seen in the data. We present three realistic extensions to the basic framework: per period fixed costs, public pension provision, and a small chance of a disastrous event in the stock market. The estimated model is able to explain observed patterns at reasonable wealth levels, while keeping to a fairly ...

Large-scale asset purchases by the Federal Reserve: did they work?
In this study, authors Joseph Gagnon, Matthew Raskin, Julie Remache and Brian Sack review the Federal Reserve?s experience with implementing the LSAPs between late 2008 and March 2010. They explain that the target fed funds rate was set as low as possible in December 2008. Thus, to further ease the stance of monetary policy as the economic outlook deteriorated, the central bank purchased substantial quantities of assets with medium and long maturities?housing agency debt, agency mortgage-backed securities (MBS) and Treasuries?to drive down private borrowing rates. ; Title of Special Issue: ...

Loss aversion, asymmetric market comovements, and the home bias
Loss aversion has been used to explain why a high equity premium might be consistent with plausible levels of risk aversion. The intuition is that the different utility impact of wealth gains and losses leads loss-averse investors to behave similarly to investors with high risk aversion. But if so, should these agents not perceive larger gains from international diversification than standard expected-utility preference agents with plausible levels of risk aversion? They might not, because comovements in international stock markets are asymmetric: Correlations are higher in market downturns ...
