Using a non-parametric programming framework, we analyze input-output ratio convergence and technical efficiency catching-up among 63 North American industries over the period 1987-2014. We first separate efficiency gaps into two components: a technical efficiency effect taking into account industry size heterogeneity and a structural component which highlights the impacts of an input-output deepening or expanding effect on technological transfer over time. Secondly, a panel data analysis is performed to link input and output price evolutions with changes in technical efficiencies and input-output mixes. Results clearly show that convergence is observed for both technical and structural components. The impact of these convergence processes on the US economy is estimated at around 0.64% of additional growth. Moreover, these two convergence processes have positive influence onto final demand prices and profitability but negative impact onto suppliers’ prices while no effect can be established on employees or capital providers’ remunerations.
