摘要：The dynamic impacts of the federal funds rate and the foreclosure rate on the log of the S&P/Case-Shiller aggregate 10-city monthly housing price index are investigated using VMA modeling techniques in the period 2000(1)–2011(3). The findings are consistent with the view that the interest rate policy of the Federal Reserve in that period that kept rates artificially low contributed to the housing bubble. Positive shocks in the foreclosure rate are shown to be associated with declines in the change in the housing price index after a lag. In addition, negative shocks in the change in the housing price index are associated with a higher foreclosure rate. The results suggest that both the change in the housing price index and the foreclosure rate create a negative externality that is dynamic.
