This article analyzes concerns about market power and inequality in a model with multiple sectors, heterogeneous abilities, endogenous labor supply, and nonlinear income taxation. Proportional markups with no profit dissipation have no effect on the economy, and a policy that reduces a nonproportional markup raises (lowers) welfare when it is higher (lower) than a weighted average of other markups. With proportional (partial or full) profit dissipation, proportional markups are equivalent to a downward shift of the distribution of abilities, and the optimal policy rule with nonproportional markups maximizes consumer plus producer surplus despite concerns for distribution and labor supply distortion.

This study builds an economic growth model of gender division labor, endogenous labor supply with nonlinear progressive income taxation. The tax income is spent on supplying public goods. The economic system consists of one production sector and one public sector. The public sector is financially supported by tax incomes. The model describes dynamic interactions of growth and gender division of labor with progressive income taxation. We simulate the model to demonstrate existence of equilibrium and motion of the dynamic system. We also examine effects of changes in different parameters on the motion of the economic system.
