COMPARISON OF THE PRODUCTIVITY LEVELS OF AUSTRIAN AND HUNGARIAN INDUSTRY: METHODS AND RESULTS

Cooperation between the Austrian and Hungarian central statistical offices in the field of industrial productivity has a history of two decades. The first comparison, carried out in 1965, was partly experimental in objective and nature. The second full scale survey took place a decade later in 1975. This was followed by a further study of about two years duration of the level of productivity and the factors influencing it in three sectors: food, metallurgy and engineering. For this study the three sectors were broken down into 31 sub‐branches and nearly 400 product groups. An important and labour‐intensive element of the comparisons was harmonization of the sector and product classification system; UN recommendations were increasingly helpful for this work, and relying upon them will be expedient also in the future. In the decade under review the productivity advantage of Austrian industry increased, from about 40 percent in 1965 to an average 75 percent in 1975. The dispersion of sectoral productivity indices around the average value was significant in both years. The similarity of the 1965 and 1975 comparisons offered an exceptional opportunity to examine the reliability of extrapolation. The investigations unambiguously demonstrated that extrapolation did not give reliable results for a period as long as ten years, primarily because of structural changes in production and changes in price weights. The most important conclusion to be drawn from the investigation of the three selected branches is its extraordinary usefulness from the economic, political and methodological points of view. A further important conclusion is that the method of comparison must be selected in the light of an extensive consideration of the output and technological structure of the branches.
