A rapidly growing literature has documented important improvements in volatility measurement and forecasting performance through the use of realized volatilities constructed from high frequency returns coupled with relatively simple reduced-form time series modeling procedures. Building on...

Current practice largely follows restrictive approaches to market risk measurement, such as historical simulation or RiskMetrics. In contrast, we propose flexible methods that exploit recent developments in financial econometrics and are likely to produce more accurate risk assessments, treating...

A large literature over several decades reveals both extensive concern with the question of time-varying betas and an emerging consensus that betas are in fact time-varying, leading to the prominence of the conditional CAPM. Set against that background, we assess the dynamics in realized betas,...

This paper utilizes Vector Auto Regression (VAR) models to analyze the interdependence among exchange rates of twelve Asian-Pacific nations, Australia, China, Indonesia, Japan, Malaysia, New Zealand, Philippines, South Korea, Singapore, Taiwan, Thailand, and Vietnam. The daily data span from...

This paper explores the impact of volatility estimation methods on theoretical option values based upon the Black-Scholes-Merton (BSM) model. Volatility is the only input used in the BSM model that cannot be observed in the market or a priori determined in a contract. Thus, properly calculating...

Spain has experienced many financial crises through its history. These financial crises have varied origins. However, they do have common threads. The current recession and subsequent debt crisis follow the same pattern. The fiscal and monetary policies of the Spanish government have played a...

The examination of U.S. crises reveals that the current financial crisis follows past patterns. An investment bubble creates excess demand for new financing instruments. During the railroad bubbles of the nineteenth century loans were issued at a pace higher than many companies could pay back....

This paper analyzes the causes and implications of recent financial crises. Financial crises in general lead to changes in both theory and practice of economics. The paper takes an historical overview. The global consensus of economic theory during the 20th century is discussed. The paper...

The economic history of the United States is riddled with financial crises and banking panics. During the nineteenth-century, eight major such episodes occurred. In the period following World War II, some believed that these crises would no longer happen, and that the U.S. had reached a time of...

This paper studies the econometrics of computed dynamic models. Since these models generally lack a closed-form solution, economists approximate the policy functions of the agents in the model with numerical methods. But this implies that, instead of the exact likelihood function, the researcher...
