The Thirlwall-Hussain model (in which output growth depends on export growth) and an ad hoc alternative (in which growth depends on imports) are estimated and compared for the U.S. The Durbin-Wu-Hausman test is used to determine the endogeneity or exogeneity of exports and imports with respect...

A refinement of Mandelbrot's technique for estimating the Mandelbrot-Levy characteristic exponent is applied to Cauchy distributed pseudorandom samples. Tables of percentage points of the test statistic are calculated under the null of a Cauchy-distributed population for various sample sizes. An...

On-site calibration technology is an important technical means for calibration of fixed gamma dose instruments in large nuclear facilities. The two key factors that affect the calibration effect are: the calibration source and the agreed true value. This paper studies the characteristics of the...

We investigate the properties of Johansen''s (1988, 1991) maximum eigenvalue and trace tests for cointegration under the empirically relevant situation of near-integrated variables. Using Monte Carlo techniques, we show that in a system with near-integrated variables, the probability of reaching...
