The Extent of Seasonal/Business Cycle Interactions in European Industrial Production

Source: RePEc


Recent literature has uncovered evidence that the seasonal pattern in industrial production changes over the business cycle, with seasonality being less pronounced in periods of high growth than in the low growth (or recession) business cycle phase. Matas-Mir and Osborn (2002) examine this effect using monthly data for various OECD countries, showing that the change in the seasonal pattern is typically concentrated in the summer months. The present paper extends this analysis in a specifically European context, by presenting measures of the extent of seasonal/business cycle interactions for industrial production series from European countries. The analysis is undertaken using a nonlinear threshold model that allows the overall mean and seasonal characteristics to change with the regime. The extent of seasonality in each regime is represented as the average absolute deviation of the steady state growth in each month from the overall steady state mean growth in that regime, with seasonality considered both over twelve months and over the summer months only. Seasonal/business cycle interaction is then measured in two ways, namely as the difference and the ratio of the regime- dependent seasonality, again separately for all months and for the summer. The results reinforce previous findings of reduced seasonality in higher growth periods, with the seasonal pattern being moderated by around 20 percent (both over the year and in the summer months) in some European countries.

    ABSTRACT: The authors use the non-parametric method proposed by Harding and Pagan (2003) to date tourism growth cycles. This study is among the first to use robust, transparent and replicable dating rules in the context of economic tourism activity cycles. On the basis of a cycle indicator function, the authors are able to establish a greater degree of cycle synchronization of tourism demand than that observed at the economic cycle level, and, by means of a recursive correlation coefficient, they conclude that this degree of cycle synchronization has increased over the years. To analyse the presence of a time lag between turning points of economic cycles and tourism demand, they suggest a lag concordance index. Observing cycles and producing dating indicator functions are important in examining potential asymmetric behaviour associated with tourism economic phases and are useful for forecasting purposes.

    ABSTRACT: We study the impact of seasonal adjustment on the properties of business cycle expansion and recession regimes using analytical, simulation and empirical methods. Analytically, we show that the X-11 adjustment filter both reduces the magnitude of change at turning points and reduces the depth of recessions, with specific effects depending on the length of the recession. A Monte Carlo analysis using Markov-switching models confirms these properties, with particularly undesirable effects in delaying the recognition of the end of a recession. However, seasonal adjustment can help to clarify the true regime when this is well underway. These results continue to hold when a seasonally non-stationary process with regime-dependent mean is misspecified as one with deterministic seasonal effects. The empirical findings, based on four coincident US business cycle indicators, reinforce the analytical and simulation results by showing that seasonal adjustment leads to the identification of longer and shallower recessions than obtained using unadjusted data.

    ABSTRACT: In this paper I compare different models, a linear and a non-linear one, for forecasting industrial production by means of some related indicators. I claim that the difficulties associated with the correct identification of a non-linear model could be a possible cause of the often observed worse performance of non-linear models with respect to linear ones observed in the empirical literature. To cope with this issue I use a non-linear non-parametric model. The results are promising, as the forecasting performance shows a clear improvement over the linear parametric model.
