Persistence, seasonality and trend in the UK egg production

This paper discusses the time-series properties of UK egg production in order to provide an empirical analysis of the possible long-run impact of the shock on the industry following the recent incidence of salmonella poisoning. Our analysis shows that although the short-run properties of the UK egg production are consistent with the presence of persistent shocks, a shock duration is unlikely to have large long run efefcts. This result is remarkably robust to the choice of the persistence measure obtained.
