Karl Gunnar Persson (born 1943) is a Scandinavian economic historian whose contribution lies mainly in comparative European economic history.

Life

Karl Gunnar Persson was born in Borås, Sweden, then a textile industry centre, and was educated at Lund University. He has spent most of his career at the Department of Economics, University of Copenhagen, Denmark, although he lives in Sweden. He was hired as a Senior Lecturer in 1975 and later became Reader and finally Professor. He is Professor Emeritus since 2013. He has been a visiting scholar at various universities such as London School of Economics, European University Institute and Australian National University.

Karl Gunnar Persson has had various administrative duties at his Department over the years, including that of Deputy Head of Department. He has been the founding president of the European Historical Economics Society[1] and one of the founding editors of the European Review of Economic History.[2] He is a fellow of the Royal Danish Academy.

In the 19060s and 1970s Karl Gunnar Persson also worked as a free lance journalist for the Swedish Radio, journals and newspapers. Persson’s early academic work was in sociometrics investigating social mobility. Educated as an economic historian, he returned to this field in the early 1980s.

Work

Pre-Industrial Economic Growth

In the monograph Pre-Industrial Economic Growth [3] he showed that the traditional Malthusian model did not have a single equilibrium characterized by subsistence income, but in fact a number of equilibria. If slow but persistent technological progress was admitted in a Malthus-Ricardo model, the equilibrium was characterized by positive population growth and income above subsistence. The level of per capita income and the rate of population growth was determined by the rate of technological progress given the rate of diminishing returns to labour.

The problem with estimating growth and income levels in pre-industrial societies is the lack of precise national income data. His approach is based on indirect estimates and relies on the possibility of inferring growth in per capita income by using data on changes in the occupational pattern and by implication the consumption pattern. The method uses Engel’s law, the idea that households spend an increasing share of an income increase on non-food items and consequently less of the income increase on food. That will have an impact on production and occupational distribution away from food production. An increase in the share of non-food producers in an economy reveals a per capita income increase. Using the method with relevant controls indicate pre-industrial income growth since Medieval times of around 0.15–0.25 per cent per year.

Market integration

In the 1990s Persson was mainly working with the analysis of market integration arguing that markets which had stochastic output shocks, like grain production, experienced a stabilization of prices when previously segmented markets were integrated. The reason was that trade dampened the local shocks since over a large area shocks were independent geographically: grain could flow from surplus to deficient areas. This strand of research was summarized in his monograph Grain markets in Europe 1500–1900.[4]

The law of one price

In subsequent work in this field Persson has investigated the operation of the law of one price, the idea that price differentials for a homogenous good traded between two locations must equal the transport costs between the two markets. He found that the quality and speed of information transmission determined the deviations from the ‘law of one price’ and that the introduction of the telegraph and the commercial press greatly reduced the deviations and increased the speed by which the ‘law of one price’ was restored after a shock in one market. He has also measured the costs, in terms of dead weight loss, of poor market integration and the subsequent welfare gains of improvements in market performance.

An Economic History of Europe

Persson has been teaching economic history for economics students during four decades and these lectures were reworked to a general textbook published as An Economic History of Europe.[5] This treatise differs from traditional textbooks in economic history by not taking up a chronological narrative. Instead it is theme and problem-oriented with separate chapters on the international monetary order, inequality, institutions and growth, knowledge transmission and convergence, globalization and so forth.

Historical demography

Persson has been working with historical demography since his becoming an Emeritus professor. In particular he is investigating the mechanisms of within-marriage fertility control before the advent of modern means of contraception. Persson is challenging the conventional view in historical demography which tend to neglect within-marriage fertility control before the modern era. He is also involved in a project refining the method of productivity estimates by using occupational data.
