This study examines the long memory behavior in gold returns during the post-Bretton Woods period using a new rescaled range technique. Unlike the conventional rescaled range analysis, the new rescaled range analysis is robust to short-term dependence and conditional heteroscedasticity found in...

A generalized.notion of cointegration, called fractional cointegration, is introduced to examine the long-run purchasing power parity hypothesis. By allowing deviations from equilibrium to follow a fractional process, the fractional cointegration analysis can capture a wider range of mean...

This study examines some finite-sample properties of a new modified Dickey-Fuller test, called the DF-GLS test, which has been shown to be more powerful than standard unit-root tests. The study shows that the lag order can significantly affect the critical values of the test. This points to the...

Response surface analysis is used to obtain approximate finite-sample critical values for the augmented Dickey-Fuller test. Previous studies estimating the critical values for the test have generally ignored their possible dependence on the lag order. This study shows that the lag order, in...

This paper examines the aggregate implications of the production smoothing model. The analysis indicates that aggregation can be a source of bias distorting tests of production smoothing based on the relative variance of production and sales. It is shown that, depending upon the relative...

This paper explores the implications of the production lag for the firm's decisions. The authors establish a significant relationship between price behavior and the length of the production lag. They show that specific results in the literature are crucially dependent upon the assumption about...

This study examines the long-term persistence in ex ante real interest rates. According to the long-run Fisher effect, ex ante real rates--the difference between nominal rates and expected inflation--should be mean-reverting and have no unit root. Empirical evidence on mean reversion has been...

We construct an empirical model for daily highs and daily lows of US stock indexes based on the intuition that highs and lows do not drift apart over time. Our empirical results show that daily highs and lows of three main US stock price indexes are cointegrated. Data on openings, closings, and...
