• 01-du-dy.R Computes responses of unemployment to changes in productivity. A comparison of two matching functions is made. One is the familiar Cobb--Douglas parameterization. The other is a nonlinear parameterization that generates larger volatility.
• 02-get-vacancies-unemployment.R Retrieves data on unemployment and job openings. The code retrieves the latest data from FRED. This code does not need to be run if the aim is replicating figures in the paper. Data used to generate the figures are located in dta/cln/.
• 03-plot-vacancies-unemployment-levels.R Plots unemployment and job openings in levels.
