Supply side effects of the Berlin rent freeze

Pekka Sagner / Michael Voigtländer in International Journal of Housing Policy

On 23 February 2020, the Berlin Senate introduced the Berlin rent freeze (‘Mietendeckel’). The law was repealed on 25 March 2021. The Berlin rent freeze was an unprecedented market intervention in the German housing market.

Housing – the new social question?

Pekka Sagner / Maximilian Stockhausen / Michael Voigtländer

Pekka Sagner / Michael Voigtländer

In this paper, we present the current state of European investments in construction. Furthermore we showed how construction investments fared in comparison to overall GFCF, noting that construction investments are still below their peak levels in 2007 for both investments in dwellings and the construction of non-residential buildings and structures.

Regional growth: Economic crisis slows European convergence

Matthias Diermeier / Markos Jung / Pekka Sagner

Up until the economic and financial crisis, economic conditions in the European regions had been converging. This process has come to a complete standstill in recent years due to lower growth in Eastern Europe and stagnation in Southern Europe.

Convergence in Europe: The poorer regions are not catching up anymore

Before the economic crisis, European regions with low economic output per inhabitant grew faster than the wealthier ones. The living conditions on the continent became more similar. Since 2010, however, the process of catching-up has been stopped.
