“…This paper proposes a solution to the standstill, which can be applied in other contexts in economic history for which similar conditions prevail. Building on the business cycle literature that identifies the cycle using factors models (Sarferaz and Uebele 2009;Ritschl et al 2016), we develop a two-stage approach to estimate GDP. In the first stage, a dynamic factor model is estimated to identify the common movement in a set of key macroeconomic variables.…”
