This article suggests how stateenterprises can be incorporated into the theoretical andempirical growth literature. Specifically, it shows that ifstate enterprises are less efficient than private firms,invest less, employ less skilled labor, and are less eagerto adopt new technology, then a large state enterprisesector tends to be associated with slow economic growth, allelse remaining the same. The empirical evidence for 1978-92indicates that, through a mixture of these channels, anincrease in the share of state enterprises in employment byone standard deviation could reduce per capita growth by oneto two percentage points a year from one country to another.
