Asset market hangovers and economic growth: U.S. housing markets
This paper presents evidence that speculative bubbles can have sizeable effects on house prices, and on housing investment. We infer that deviations of asset prices from fundamental values may have serious consequences for real activity, and explore some policy implications. The analysis relies on a panel of U.S. state-level data covering 1973-1996.

Determinants of current risk premiums
This paper presents a theoretical model of exchange-rate determination intended to address the forward premium puzzle. It also explains the empirical observation that risk premiums depend on interest differentials. The model's closed-form solution indicates that currency risk premiums depend on two factors: interest differentials and the current deviation of the exchange rate from its long-run equilibrium. If speculators have an alternative to exchange-rate speculation, then there is no presumption that uncovered interest parity holds even approximately in long-run equilibrium. The model is ...

Head and shoulders: not just a flaky pattern
This paper evaluates rigorously the predictive power of the head-and-shoulders pattern as applied to daily exchange rates. Though such visual, nonlinear chart patterns are applied frequently by technical analysts, our paper is one of the first to evaluate the predictive power of such patterns. We apply a trading rule based on the head-and-shoulders pattern to daily exchange rates of major currencies versus the dollar during the floating rate period (from March 1973 to June 1994). We identify head-and-shoulders patterns using an objective, computer-implemented algorithm based on criteria in ...

Second district housing prices: why so weak in the 1990s?
Between 1990 and 1997, poor economic fundamentals and a prolonged hangover from excessively rapid growth in the 1980s caused house prices in the New York metropolitan area to grow much more slowly than prices nationwide; these factors played a smaller role in the decline of upstate New York's house prices relative to the nation's.

Asset market hangovers and economic growth
During the early 1990s, asset prices and investment were unusually weak throughout the industrial world. This paper highlights this stylized fact, and connects it with another: in most of the industrial world, asset markets boomed for several years before collapsing around 1989. The paper suggests that the sluggish asset markets and investment growth of the early 1990s may represent, in part, symptoms of an "asset market hangover," that is, the lingering effects on real activity of collapsing speculative bubbles. The analysis relies on cross-country data for equity and real estate markets ...

Introduction
This volume of the Economic Policy Review, "Special issue on the economic effects of September 11," explores some of the key economic consequences of the attacks of September 11. The six articles that make up the volume address several important questions: how great were the losses in New York City on September 11 and in the difficult months thereafter? How much will the nation spend to prevent future attacks? Did the destruction of information and infrastructure impair the functioning of the payments and securities settlement systems, and what steps minimize further damage? Will these ...

Stop-loss orders and price cascades in currency markets
In this paper, I provide evidence that currency stop-loss orders contribute to rapid, self-reinforcing price movements, or "price cascades." Stop-loss orders, which instruct a dealer to buy (sell) a certain amount of currency at the market rate once the rate has risen (fallen) to a prespecified level, generate positive-feedback trading. Theoretical research on the 1987 stock market crash suggests that such trading can cause price discontinuities, which would manifest themselves as price cascades. ; My analysis of high-frequency exchange rates offers three main results that provide ...

Identifying noise traders: the head-and-shoulders pattern in U.S. equities
This paper identifies a specific set of agents as noise traders in U.S. equity markets, and examines their effects on returns. These agents, who speculate using the "head-and-shoulders" chart pattern, are shown to qualify as noise traders because (1) trading volume is exceptionally high when they are active, and (2) their trading is unprofitable. Head-and-shoulders sales lower prices and vice versa, effects that disappear within two weeks.

Short-term speculators and the origins of near-random-walk exchange rate behavior
This paper suggests that normal speculative activity could be a source of random-walk exchange rate behavior. Using a noise trader model to analyze very short-term exchange rate behavior, it shows that rational, risk-averse speculators will smooth the impact of shocks to exchange rate fundamentals. With sufficient speculative activity, an exchange rate could become statistically indistinguishable from a random walk, regardless of the generating processes of its fundamental determinants. ; This result may help resolve the apparent inconsistency between the observed behavior of floating ...
