We build a model of optimal fixed-rate mortgage refinancing with fixed costs and inattention and derive a new sufficient statistic that can be used to measure inattention frictions from simple moments of the rate gap distribution. In the model, borrowers pay attention to rates sporadically so...

There are large cross-sectional differences in how often US borrowers refinance mortgages. In this paper, we develop an equilibrium mortgage pricing model with heterogeneous borrowers and use it to show that equilibrium forces imply important cross-subsidies from borrowers who rarely refinance...

This chapter discusses recent developments in inflation forecasting. We perform a horse-race among a large set of traditional and recently developed forecasting methods, and discuss a number of principles that emerge from this exercise. We find that judgmental survey forecasts outperform...
