Introduction- Research Questions
Due to strong reliance on the construction sector, the PIGS countries were severely hit by the downturn in the housing market
The literature and policy makers frequently identified monetary policy as a relevant factor in the formation of asset bubbles.
– (ECB, 2011) Simple deviations of the money and credit aggregates from a trend that exceed a given threshold provide a useful predictor of costly boom and bust cycles
– (ECB, 2012) Ballooning credit and spending excesses overheated the economy in Ireland and misdirected resources during the booming years before the crisis
This paper addresses two central questions
– 1) To which extent did the PIGS countries experience real estate bubbles throughout the period from 1999 to 2012?
– 2) What is the role of the monetary policy of the ECB in the formation of property bubbles?

Conclusion & Discussion
21 April 2023 Philipp Klotz 18
1) To what extend did the PIGS countries experience real estate bubbles throughout the period from 1999 to 2012?
– Spain and Ireland experienced the largest bubble– Followed by Portugal with a small positive bubble and Greece with a negative bubble
2) What is the role of the monetary policy of the ECB in the formation of property bubbles?
Why are there differences?

Conclusion & Discussion
21 April 2023 Philipp Klotz 19
Differences in the financial system– Interest rate channel: Interest rates set by the ECB are transmitted differently – Credit channel: Monetary policy affects domestic credit supply differently
Diverging Fiscal & Macro prudential policies
1) Countries with low interest and tax rates as well as relatively high LTV-ratios have the potential to experience large positive property bubbles
2) Central bank’s policies are crucial to trigger the boom & burst of housing bubbles

Portugal 42% 71%
Ireland 20% 83%
Greece 0% 73%
Spain 18% 72.5%
