We formulate a version of the growth model in which production is carried out by heterogeneous plants and calibrate it to US data. In the context of this model we argue that differences in the allocation of resources across heterogeneous plants may be an important factor in accounting for cross-country differences in output per capita. In particular, we show that policies which create heterogeneity in the prices faced by individual producers can lead to sizeable decreases in output and measured TFP in the range of 30 to 50 percent. We show that these effects can result from policies that do not rely on aggregate capital accumulation or aggregate relative price differences. More generally, the model can be used to generate differences in capital accumulation, relative prices, and measured TFP.

AbstractProductivity is at the core of the large differences in income per capita across countries. What accounts for international productivity differences? I discuss cross‐country differences in the allocation of inputs across heterogeneous production units—misallocation—as a potential factor in accounting for aggregate productivity. Policies and institutions generating misallocation are prevalent in poor and developing countries and may also be responsible for differences in the selection of operating producers and technology used, contributing substantially to aggregate productivity differences across countries.
