A pair of simple modifications-in the forecast error and forecast error variance-to the Kalman filter recursions makes possible the filtering of models in which one or more state variables is truncated normal and latent. Such recursions are broadly applicable to macroeconometric models, such as...

This paper introduces a compound GARCH/markov switching model to add flexibility to the GARCH model in order to model the volatilities of exchange rates in target zones subject to realignments. The compound volatility model endogenizes the weights given to realignments (and all other shocks) in...

The Chicago Board Options Exchange concurrently listed European-style and American-style options on the Standard and Poor's 500 Index from April 2, 1986 through June 20, 1986. This unique time period allows for a direct measurement of the early-exercise premium in American-style index options....

Previous time series applications of qualitative response models have ignored features of the data, such as conditional heteroskedasticity, that are routinely addressed in time-series econometrics of financial data. This article addresses this issue by adding Markov-switching heteroskedasticity...

In this paper, we estimate (by maximum likelihood) the parameters of univariate fractionally integrated real exchange rate time series models, and test for autoregressive unit roots on the alternative of a covariance stationary long-memory process. We use quarterly dollar-based real exchange...

Stockman and Dellas (1986) demonstrated that in the presence of complete international asset markets, the relative welfare implications of a small tariffare reversed from standard trade theory. This paper examines the robustness of that result to change in preference parameters and asset market...

The purpose of this study is to examine the effects of State regulation that determines the extent of professional independence of advanced practice nurses (APNs). We find that in States where APNs have acquired a substantial amount of professional independence, the earnings of APNs are...

We estimate a multivariate ARFIMA model to illustrate a cointegration testing methodology based on joint estimates of the fractional orders of integration of a cointegrating vector and its parent series. Previous cointegration tests relied on a two-step testing procedure and maintained the...

To the surprise of many market watchers, Thailand's exchange-rate peg to the dollar collapsed in July 1997, leading to similar rounds of currency devaluations in other East Asian countries. This study seeks to determine if there were identifiable contrasts in implementation between Thailand's...
