In this paper, we propose two classes of test statistics for detecting a break at an unknown date in panel data models with time trend. The first one is the fluctuation test of Ploberger-Kramer-Kontrus (1989). The second one is based on the mean and exponential Wald statistics of Andrew and...

In this paper we study the limiting distributions for ordinary least squares (OLS),fixed effects (FE), first difference (FD), and generalized least squares (GLS) estimators in a linear time trend regression with a one-way error component model in the presence of serially correlated errors. We...

Using recent data, this paper investigates whether changes in oil prices have the expected effects on the US economy. Cointegration analysis and vector error correction models are employed in order to evaluate the impact of changing oil prices on US output and inflation. Further, impulse...

In this paper cointegration analysis is used to examine the long-run relationship between money, prices, output, and interest rates. This paper finds convincing evidence in support of the quantity theory of money using time series data from the United States.
