To explain the process of development historically documented, we consider a model with three economic sectors (agriculture, manufacturing and services) characterized by different productivity gains and by saturation levels in the demands of agricultural and manufactured goods. Our parsimonious model captures within a single framework the process of development which is characterized by the structural changes in the workforce across sectors, variable growth rates (an initial “Malthusian regime” exhibiting slow growth, a fast growth regime after a takeoff, and a gradual slow down leading to a possible new stagnation) and the relative evolutions of prices across sectors. Reasonable calibration generates results quantitatively close to the observed empirical facts.
