Abstract: | The paper contributes to the explanation of the large differences in cross-country productivity performance by modelling and
testing the effects of social barriers to communication on productivity and capital accumulation. In an optimal growth model,
social barriers to communication, which impede the formation of knowledge connections, are shown to reduce both transitory
and steady-state levels of total factor productivity (TFP), per capita consumption and reproducible capital. Empirical testing
yields a robust and theoretically consistent result: linguistic barriers to communication reduce productivity and capital
accumulation. The findings provide an explanation for cross-country differences in TFP, and fresh insights into how productivity
‘catch up’ may be initiated.
