La domanda primaria di caffè in Italia: una analisi statistica

Abstract

In this paper we estimate the long run economic relationship between ground coffee domestic consumption, advertising expenditure and consumer price during the period 1981-1992. After verifying that all these variables are cointegrated, we make use of a dynamic specification which incorporates an error correction mechanism (ECM). The estimates of the cointegration relationships point out that advertising expenditure doesn't affect coffee consumption level in the short run, while there is causality in both directions between coffee consumption and consumer price with a one month lag. Advertising expenditure has nevertheless a significant effect on consumption level in the long run.
