Nice paper by Seppo Honkapohja of Bank of Finalnd. Explains how and why Nordics did financial liberalisation and how it led to a crisis later on:
The financial liberalization in the four Nordic countries (Denmark, Finland, Norway, and Sweden) that took place mostly in the 1980s led to a major financial crisis in three of those countries. The crises in Finland, Norway, and Sweden are among the deepest financial crises in advanced market economies since World War II. Denmark experienced some banking problems but managed to avoid a systemic crisis. This paper reviews the process of liberalization and discusses the reasons why Finland, Norway, and Sweden drifted into financial and economic crises.
The particular coverage on how liberalisation was sequenced is interesting read..
