This article explores nonlinearities in the response of speculators' trading activity to price changes in live cattle, corn, and lean hog futures markets. Analyzing weekly data from March 4, 1997 to December 27, 2005, we reject linearity in all of these markets. Using smooth transition...

This study employs panel smooth transition regression (PSTR) models with different lagged variables of earnings components as regressor to evaluate earnings persistence effects. The models can resolve collinearity problems between predictors, reflect firms' volatile or irregular earnings streams...

This paper presents an analysis of the relationship between per capita water use and per capita income for 65 countries, over the period 1962–2008, within the framework of the so-called environmental Kuznets curve (EKC). Consistent with the existing literature, a polynomial fixed effects model...

This paper investigates the threshold effects on the impacts of fundamentals (i.e., incomes, exchange rates, oil prices, and import-weighted distances) on China's trade balances with the G7 countries between 1975 and 2010 by using a panel smooth transition regression (PSTR) model with the...
