GDP has been central to research in economic development. New historical national accounts for Norway provide additional information on economic growth and development because they are more comprehensive than existing data. The new series indicate the need for revisions to Norwegian growth history. Specifically, higher growth rates were achieved during the last decades of the nineteenth century and significantly lower growth rates occurred between 1918 and 1930. The new data confirm that Norwegian ‘take off’ emerged during the 1890s.
There are four fundamental differences between the new and old series. First, the new data encompass a longer time period. Second, it includes significantly more industries. Thirdly, the new series are calculated according to a different base series. Finally, the new series represent 17 main series and 78 sub-series, compared to just seven for the old series.
I use a double deflation technique (deflating both the input and output series). This methodology is applied to primary and secondary industries. For most of the service industries, single deflation is applied (deflating value-added only). The aggregated GDP series in fixed prices are reported in Figure 1. This new series confirms existing trends in Norwegian development and reveals considerable economic growth in the nineteenth and twentieth centuries.
However, we observe some significant differences. The new series indicates significantly higher growth at the end of the 19th century, and lower growth between 1918 and 1930. The new series also reflect upheavals and crises better than the old. For example, in the new series, 1857 was the last year primary industries were the largest sector – some 15 years earlier than reported in the old series.
Scholars disagree when Norway became industrialised. According to the new series manufacturing experienced its first growth-spurt around 1850. However, the most prominent burst of activity emerged in the 1890s, with the introduction of hydroelectricity. Comparing the new series with those of Denmark and Sweden, improves the relative performance of Norway in the second half of nineteenth century (Figure 2).
New and improved GDP series for Norway covering the period 1816-2019, suggest that views on historical growth and development need revision. In contrast to previous views, economic growth was significantly higher during the last decades of the nineteenth century but correspondingly lower between 1918 and 1930. This new evidence also suggests that Norway’s performance during the second half of the nineteenth century was relatively better than that of Denmark and Sweden, and that Norway’s ‘take-off’ started in the 1890s.
