Learning-by-doing in two sectors, production structure, leisure and optimal endogenous growth

A model with two different production sectors and endogenous growth based on the accumulation of sector-specific human capital due to learning-by-doing is presented. Accumulation of experience is measured by means of sectoral production output aggregated over time. Growth is controlled by a dynamic optimisation of the use of time for working in the different sectors or for leisure. Transitional dynamics of production growth, especially of structural change towards a 'new' sector (with relatively scarce experience), of the optimal sectoral distribution of working time and of leisure as well as the corresponding steady state levels are derived and a numerical simulation is performed.
