Section 3 discusses less traditional models, specifically nonlinear seasonal models and models for seasonality in variance …. Such nonlinear models primarily concentrate on interactions between seasonality and the business cycle, either using a …

This paper examines the relevance of incorporating seasonality in agricultural supply models. Former studies have … eliminated the problem of seasonality by using seasonally adjusted data. Recent developments in cointegration techniques allow … the comprehensive modelling of error-correcting structures in the presence of seasonality. We consider a four …
