One measure of the health of the Social Security system is the difference between the market value of the trust fund and the present value of benefits accrued to date. How should present values be computed for this calculation in light of future uncertainties? We think it is important to use market value. Since claims on accrued benefits are not currently traded in financial markets, we cannot directly observe a market value. In this paper, we use a model to estimate what the market price for these claims would be if they were traded.

This article starts by discussing the concept of "inflation hedging" and provides some estimates of "inflation betas" for standard bond and well-diversified equity indices for over 45 countries. We show that such standard securities are poor inflation hedges. Expanding the menu of assets to foreign bonds, real estate and gold only improves matters marginally. This indicates a potentially important role for inflation index linked bonds.

If an investor wants to form a portfolio of risky assets and can exert effort to collect information on the future value of these assets before he invests, which assets should he learn about? The best assets to acquire information about are ones the investor expects to hold. But the assets the investor holds depend on the information he observes. We build a framework to solve jointly for investment and information choices, with general preferences and information cost functions.

We study a dynamic overlapping generations model where the population growth rate is stochastic, or can experience gradual but persistent changes. This leads to changes in the demographic makeup of the economy across the young, middle aged (who do the principal saving) and the old (who sell their assets to finance consumption).

We present a tractable, linear model for the simultaneous pricing of stock and bond returns that incorporates stochastic risk aversion. In this model, analytic solutions for endogenous stock and bond prices and returns are readily calculated. After estimating the parameters of the model by the general method of moments, we investigate a series of classic puzzles of the empirical asset pricing literature.

This paper analyzes China's experience under U.S. apparel and textile quotas. It makes use of a new database that tracks U.S. trading partners' performance under the quota regimes established by the global Multifiber Arrangement (1974 to 1995) and subsequent Agreement on Textiles and Clothing (1995 to 2005). We find that China was relatively more constrained under these regimes than other countries and that, as quotas were lifted, China's exports grew disproportionately. When the ATC finally ended in 2005, China's exports surged while those from nearly all other regions fell.

We develop a model of hedge fund returns, which reflect the contractual relationships between a hedge fund, its investors and its prime brokers. These relationships are modeled as short option positions held by the hedge fund, wherein the "funding option" reflects the short option position with prime brokers and the "redemption option" reflects the short option position with the investors. Given an alpha producing human capital, the hedge fund's ability to deploy leverage is shown to be sharply constrained by the presence of these short options.

In October 2003, leading Dutch supermarket chain Albert Heijn slashed prices up to 30% on more than 1,000 items to counter a loss in market share caused by consumer perception of high prices. AH continued the strategy for the ensuing three years, forcing competing supermarkets to match the markdowns or risk customer defections. Game theory adherents and analysts questioned the strategy, noting price wars often jeopardize profits of both individual companies and their industries.

This article complements the structural New Keynesian macro framework with a no-arbitrage affine term structure model. Whereas our methodology is general, we focus on an extended macro model with unobservable processes for the inflation target and the natural rate of output that are filtered from macro and term structure data. We find that term structure information helps generate large and significant parameters governing the monetary policy transmission mechanism. Our model also delivers strong contemporaneous responses of the entire term structure to various macroeconomic shocks.
