This paper undertakes a comparative analysis of the office market performance, measured by rents, in two dynamic Nordic office centres Helsinki and Stocholm. A set of factors are considered to study the cyclical activity in rents in these markets. These factors capture the national and regional economic dynamism in the respective office centres and the effect of particular industries, such as the technology sectors, on these two office markets. The study also provides evidence on the degree to which the office rental cycles in Helsinki and Stocholm are synchronous and explanations are put forward. Finally, rent forecasts in these two markets are performed. These forecasts are based on alternative economic and industry performance scenarios.
