This paper presents a general, nonlinear version of existing multifactor models, such as Longstaff and Schwartz (1992). The novel aspect of our approach is that rather than choosing the model parameterization out of thin air,' our processes are generated from the data using approximation methods...

This paper studies three different measures of monthly stock market volatility: the time-series volatility of daily market returns within the month; the cross-sectional volatility or 'dispersion' of daily returns on industry portfolios, relative to the market, within the month; and the...

In this paper we study how volatility in monetary policy affects economic performance in the presence of endogenously chosen information structures. To isolate the effects produced by the interaction of uncertainty in monetary policy and (possibly) asymmetric information, we consider a model in...

We evaluate the performance of different models for the covariance structure of stock returns, focusing on their use for optimal portfolio selection. Comparisons are based on forecasts of future covariances as well as the out-of-sample volatility of optimized portfolios from each model. A few...

Using high-frequency data on Deutschemark and Yen returns against the dollar, we construct model-free estimates of daily exchange rate volatility and correlation, covering an entire decade. In addition to being model-free, our estimates are also approximately free of measurement error under...

It depends. If volatility fluctuates in a forecastable way, then volatility forecasts are useful for risk management; hence the interest in volatility forecastability in the risk management literature. Volatility forecastability, however, varies with horizon, and different horizons are relevant...

This paper examines the effect of volatility on the costs and benefits of financial market integration. The basic framework combines the costly state verification model and the contract enforceability approach. The welfare effects of financial market integration are assessed by comparing welfare...

Current debates on globalization have tended to focus on financial market volatility and contagion. In fact, many proponents of the imposition of some form of capital restrictions in emerging markets have argued that these would help reduce or even eliminate spillover across emerging market....

The paper analyzes the impact of financial liberalizations and reforms in emerging markets on the dynamics of capital flows to these markets, using a simple model of international investors' behavior. We first show that the gradual nature of liberalizations, combined with the cost of absorbing...

A number of countries have delayed the opening of their capital markets to international" investment because of reservations about the impact of foreign speculators on both expected" returns and market volatility. We propose a cross-sectional time-series model that attempts to" assess the impact...
