RT Journal Article T1 On the Substitutability between Paid-employment and Self-employment: Evidence from the Period 1969–2014 in the United States A1 Congregado Ramírez de Aguilera, Emilio A1 Golpe Moya, Antonio Aníbal A1 Esteve, Vicente AB This paper provides estimates of the elasticity of substitution between operational andmanagerial jobs in the US economy during the years 1969–2014, derived from an aggregate CESproduction function. Estimating the long-term relationship between (the log of) the aggregateemployment/self-employment ratio and (the log of) the returns from paid-employment relativeto self-employment and testing for structural breaks, we report different estimates of the elasticityof substitution in each of the two regimes identified. To this end we apply the methodology oninstability tests proposed in Kejriwal and Perron (2008, 2010) as well as the cointegration testsdeveloped in Arai and Kurozumi (2007) and Kejriwal (2008). Our results help to understand andinterpret one of the most intriguing aspects in the evolution of self-employment rates in developedcountries: the reversal of the trend in self-employment rates. Our estimates show that a higher level ofdevelopment is associated with a greater number of entrepreneurs and smaller firms. Some rationalesfor understanding the growth of the elasticity between paid-employment and self-employment,including the recent trends in the digital economy, are also suggested.
