Recovering market expectations of FOMC rate changes with options on federal funds futures
This paper demonstrates how options on federal funds futures, which began trading in March 2003, can be used to recover the implied probability density function (PDF) for future Federal Open Market Committee (FOMC) interest rate outcomes. The discrete nature of the choices made by the FOMC allows for a very straightforward recovery of the implied PDF using ordinary least squares (OLS) estimation. This simple recovery method stands in contrast to the relatively complicated PDF recovery techniques developed for options written on assets such as equities, foreign exchange, or commodity futures ...

Purchasing power parity and uncovered interest rate parity: the United States 1974-1990
This paper examines the factors behind long-run movements of the dollar. Most recent work has concluded that structural exchange rate models explain only a small proportion of exchange rate movements. However, many economists still find the theory that links exchange rates and interest rates persuasive. We investigate the relationship between exchange rates, prices, and interest rates using multivariate maximum likelihood cointegration tests. In particular, we explicitly test for purchasing power parity and uncovered interest rate parity when using nominal exchange rates, and implicitly test ...

War and peace: recovering the market's probability distribution of crude oil futures prices during the Gulf crisis
This paper investigates the market's expectations for oil prices during the Persian Gulf crisis. To do so a general method for using options markets to recover the implied distribution for futures prices is developed. The method applies to a wide class of distributions. In particular, it is not limited to those distributions arising from diffusion or jump-diffusion processes.

An option for anticipating Fed action
Options contracts on federal funds futures, a new financial instrument introduced earlier this year, can be analyzed to gauge public expectations of future Fed actions. The real bonus is that they can detect differences of opinion when markets see more than two possible outcomes for an FOMC meeting as well as the likelihood associated with each.

Option prices, exchange market intervention, and the higher moment expectations channel: a user’s guide
A vast literature on the effects of sterilized intervention by the monetary authorities in the foreign exchange markets concludes that intervention systematically moves the spot exchange rate only if it is publicly announced, coordinated across countries, and consistent with the underlying stance of fiscal and monetary policy. Over the past fifteen years, researchers have also attempted to determine if intervention has any effects on the dispersion and directionality of market views concerning the future exchange rate. These studies usually focus on the variance around the expected future ...

Using options prices to infer PDF'S for asset prices: an application to oil prices during the Gulf crisis
We develop a general method to infer martingale equivalent probability density functions (PDFs) for asset prices using American options prices. The early exercise feature of American options precludes expressing the option price in terms of the PDF of the price of the underlying asset. We derive tight bounds for the option price in terms of the PDF and demonstrate how these bounds, together with observed option prices, can be used to estimate the parameters of the PDF. We infer the distribution for the price of crude oil during the Persian Gulf crisis and find the distribution differs ...

Foreign exchange and the liquidity trap
When short-term interest rates hover near zero, central banks may have difficulty offsetting downward momentum on prices and economic activity through traditional monetary-policy channels, since commercial banks have little incentive to make loans. Economists refer to this situation as a liquidity trap. Do exchange rate targets and foreign exchange operations, as some have suggested, offer a way to escape such a trap?

Alternative approaches to real exchange rates and real interest rates: three up and three down
This paper examines the relationship between real exchange rates and real interest rates using three different approaches across four currencies and two horizons with 20 years of data. Each approach gives some encouragement that this relationship might hold, but each approach also encounters problems establishing the form or usefulness of the relationship. On balance, this paper contributes to the literature by finding more encouraging results than in earlier studies, but it still remains to be demonstrated that the real exchange rate-real interest rate relationship is the linchpin to ...

FOMC communications and the predictability of near-term policy decisions
In February 1994, the FOMC began a new era in transparency, gradually building a communications apparatus that conveys information about the Committee?s decisions and expectations. Has the new apparatus improved the public?s ability to predict FOMC interest rate decisions? New research based on the prices of fed funds futures shows that over the past decade, it has, especially over horizons of two to three months.
