March 2017Regional Heterogeneity and Monetary Policy
with Andreas Fuster, Erik Hurst, Joseph Vavra: w23270
We argue that the time-varying regional distribution of housing equity influences the aggregate consequences of monetary policy through its effects on mortgage refinancing. Using detailed loan-level data, we show that regional differences in housing equity affect refinancing and spending responses to interest rate cuts but that these effects vary over time with changes in the regional distribution of house price growth and unemployment. We then build a heterogeneous household model of refinancing and use it to explore the aggregate implications for monetary policy arising from our regional evidence. We find that the 2008 equity distribution made spending in depressed regions less responsive to interest rate cuts, thus dampening aggregate stimulus and increasing regional consumption inequal...
February 2016The Aggregate Implications of Regional Business Cycles
with Erik Hurst, Juan Ospina: w21956
We argue that it is difficult to make inferences about the drivers of aggregate business cycles using regional variation alone because (i) the local and aggregate elasticities to the same type of shock are quantitatively different and (ii) purely aggregate shocks are differenced out when using cross-region variation. We highlight the importance of these confounding factors by contrasting the behavior of U.S. aggregate time-series and cross-state patterns during the Great Recession. In particular, using household and scanner data for the US, we document a strong relationship across states between local employment growth and local nominal and real wage growth. These relationships are much weaker in US aggregates. In order to identify the shocks driving aggregate (and regional) business cycl...
