α: calibrated so average coauthorship-adjusted count equals average raw count
This paper explores the secular decline in the employment share in agriculture as a result of productivity growth in the agricultural sector. I study an equation that states that employment share in agriculture is determined by the subsistence constraint and productivity in agriculture. Given the calibrated value for subsistence level of consumption in agriculture, labor productivity in this sector implies a share of employment in agriculture in the model that turns out to be very close to the data for a variety of countries between 1963 and 2005.
