Stability And Consistency

Recent literature dealing with supply-side and demand-side Input — Output models appears to contain some confusion or at least imprecision in the use of ‘stability’, ‘joint stability’, and ‘consistency’. This comment contains a tentative proposal for terminological conventions with respect to the three concepts. These thoughts are offered against the backdrop of a recent paper by Deman which illustrates the definitional problems.

Stability And Consistency

A comment by Miller was published in the August 1989 issue of Environment and Planning A, which makes an intriguing comparison of a paper by Chen and Rose with one by myself. His comment concerns the uses of various terminologies in the literature on supply-driven and demand-driven input—output models and the claims to have defined terms such as ‘stability’, ‘joint stability’, and ‘consistency’. Further, generalizations are made on the basis of a specific set of aggregated data for the US economy to show that biproportional changes suggested in my theorem are unlikely to be observed in the real world. I will show that Miller adds no illumination to the issues of ‘stability’ or ‘consistency’, and that, in fact, his comment accomplishes nothing of import. His comment could also leave us with the impression that the USA is the only ‘real-world’ example worthy of comment.

In this paper we present a forecast of the impact of measures to stem Covid-19 on the Spanish economy at a highly disaggregate level, using input-output techniques. Our estimations cover the period 2020-2021, and we consider two scenarios depending on the possibility of a second wave of massive infections in the autumn of 2020. In 2020, the lockdown of the population and the shutdown of a large part of the production system for several weeks are a supply-side shock that will be followed by a demand-side shock whose impact is expected to be even larger. In 2021 there will be some recovery, although we believe that it will not be sufficient for offsetting the initial negative shock. al negative shock.
