• Resumen

  • The accession of Spain to the European Economic Community, now the European Union, entailed major changes for the milk sector. We try to determine whether the structural adjustment processes of the firm triggered by the changing environment present irreversibilities using a adjustment costs dual model. We modify the model proposed by Chang and Stefanou (1988) in order to incorporate a theoretically more robust treatment of the zero-investment regime in quasi-fixed factors. The empirical analysis reveals that strong irreversibilities are present in the adjustment processes: speeds of adjustment are distinct in investment and disinvestment processes, and there are zero-investment regimes.
