The adaptive markets hypothesis posits that trading strategies evolve as traders adapt their behavior to changing circumstances. This paper studies the evolution of trading strategies for a hypothetical trader who chooses portfolios from forex technical rules in major and emerging markets, the...

Characterizing asset price volatility is an important goal for financial economists. The literature has shown that variables that proxy for the information arrival process can help explain and/or forecast volatility. Unfortunately, however, obtaining good measures of volume and/or order flow is...

This chapter reviews the rapid advances in foreign exchange volatility modeling made in the last three decades. Academic researchers have sought to fit the three major characteristics of foreign exchange volatility: intraday periodicity, autocorrelation and discontinuities in prices. Early...

We analyze comovements in four measures of budget surpluses for 18 OECD countries for 1980–2008 with a dynamic latent factor model. The world factor in national budget surpluses declines substantially in the 1980s, rises throughout much of the 1990s to a peak in 2000, before declining again in...

The adaptive markets hypothesis posits that trading strategies evolve as traders adapt their behavior to changing circumstances. This paper studies the evolution of trading strategies for a hypothetical trader who chooses portfolios from foreign exchange (forex) technical rules in major and...

Previous research has established that the Federal Reserve's large scale asset purchases (LSAPs) significantly influenced international bond yields. We use dynamic term structure models to uncover to what extent signaling and portfolio balance channels caused these declines. For the U.S. and...

Event studies show that Fed unconventional announcements of forward guidance and large scale asset purchases had large and desired effects on asset prices but do not tell us how long such effects last. Wright (2012) used a structural vector autoregression (SVAR) to argue that unconventional...

This article analyzes financial market reactions to the Russia-Ukraine war with a focus on the opening weeks. Markets did not completely anticipate the war, and asset price reactions strengthened from the first week—when there were hopes for a quick resolution—to the second week, when prices...

We analyze the intertemporal stability of excess returns to technical trading rules in the foreign exchange market by conducting true, out-of-sample tests on previously studied rules. The excess returns of the 1970s and 1980s were genuine and not just the result of data mining. But these profit...
