With another real estate boom-bust bringing woes to the world economy, a quest for a better policy toolkit to deal with these boom-busts has begun. Macroprudential measures could be in such a toolkit. Yet, we know very little about their impact. This paper takes a step to fill this gap by analyzing the Korean experience with these measures. We find that loan-to-value and debt-to-income limits are associated with a decline in house price appreciation and transaction activity. Furthermore, the limits alter expectations, which play a key role in bubble dynamics.

Has lobbying by financial institutions contributed to the financial crisis? This paper uses detailed information on financial institutions' lobbying and mortgage lending activities to answer this question. We find that lobbying was associated with more risk-taking during 2000-07 and with worse outcomes in 2008. In particular, lenders lobbying more intensively on issues related to mortgage lending and securitization (i) originated mortgages with higher loan-to-income ratios, (ii) securitized a faster growing proportion of their loans, and (iii) had faster growing originations of mortgages. Moreover, delinquency rates in 2008 were higher in areas where lobbying lenders' mortgage lending grew faster. These lenders also experienced negative abnormal stock returns during the rescue of Bear Stearns and the collapse of Lehman Brothers, but positive abnormal returns when the bailout was announced. Finally, we find a higher bailout probability for lobbying lenders. These findings suggest that lending by politically active lenders played a role in accumulation of risks and thus contributed to the financial crisis.

This paper links the current subprime mortgage crisis to a decline in lending standards associated with the rapid expansion and changes in the structure of this market. We show that lending standards declined more in areas that experienced faster credit growth. We also find that the entry of new lenders contributed to the decline in lending standards. The results are robust to controlling for house price appreciation, mortgage securitization, and other economic fundamentals, and to several robustness tests controlling for endogeneity. The results are consistent with the predictions of recent models based on asymmetric information, and shed light on the relationship between credit booms and financial instability.
