The importance of frequency in estimating labour market transition rates

Labour market transition rates are typically estimated using survey data, which are mainly carried out at monthly or quarterly frequency. I argue that rates from surveys at different frequencies are not comparable, even if corrected for time aggregation. I estimate labour market transition rates using monthly and quarterly frequency CPS data. I apply a time-aggregation correction to make them comparable. I find notable differences in terms of levels and volatilities. While the continuous time-aggregation correction does not alter the unemployment decomposition using the monthly survey, it does so when using the quarterly survey.
