In this paper, Markov chain Monte Carlo sampling methods are exploited to provide a unified, practical likelihood-based framework for the analysis of stochastic volatility models. A highly effective method is developed that samples all the unobserved volatilities at once using an approximating...

In recent years, wavelets have become widely used in physics, engineering, and mathematics. They have been used for signal processing, image processing, numerical computation, and data compression. Wavelets have not, however, been used very much in the fields of Economics, Econometrics, and...

We present several Markov chain Monte Carlo simulation methods that have been widely used in recent years in econometrics and statistics. Among these is the Gibbs sampler, which has been of particular interest to econometricians. Although the paper summarizes some of the relevant theoretical...

We have collected data on the one-year-ahead income expectations of members of American households in our Survey of Economic Expectations (SEE), a module of a national continuous telephone survey conducted at the University of Wisconsin. The income- expectations questions take this form: "What...

The authors examine the issue of lag-length selection in the context of a structural vector autoregression (VAR) and a vector error-correction model with long-run restrictions. First, they show that imposing long- run restrictions implies, in general, a moving-average (MA) component in the...

The notion that lack of knowledge undermines the economic performance of African countries is deeply and widely held to be true. Yet evidence for the basis of that truth is few and far in-between. This paper first describes a production function approach to the creation of knowledge of African...

Demand for money is an important macroeconomic relationship. Its stability has implications for the choice of monetary policy targets. This paper estimates demand for narrow money in Fiji and evaluates its robustness and stability. It is found that there is a well determined stable demand for...
