A recent NIESR paper by Armstrong and Davis (November 2014 (£)) compares the last two booms and busts in major OECD country housing markets. The authors present a thoughtful macroeconomic analysis of national housing markets and from there conduct panel data analysis of the determinants of house prices focusing on financial, debt and related variables.
The authors argue that comparison of the two most recent housing market cycles (1985-94 and 2002-11) can test the hypothesis that there was something unique about the most recent boom and its aftermath. They state that the housing market is widely considered to be the main cause of the global financial crisis (quoting such authorities as the IMF). However, the authors come away from overall reading of the data for the two cycles unconvinced. In their view the two cycles are sufficiently similar that it difficult to draw the conclusion that the most recent cycle is different in meaningful ways: it is certainly not unique. The implications is that if the received wisdom is incorrect and other factors were important in causing the crisis then macro-prudential policies in countries like the UK may be incorrectly targeted at the control of house prices and mortgage lending.
We are interested in this broad area for several reasons: why did economists miss the bubble nature of the housing market and its departure form fundamentals? Why did they miss the downturn in national housing markets? How plausible are the microfoundations of the models being used to analyze the housing market and explain what is actually going on? What do these analytical weaknesses tell us about the health or otherwise of economics and its capacity to evolve and learn for future challenges? [Read more…]
