|January 2016||Lack of Selection and Limits to Delegation: Firm Dynamics in Developing Countries|
with Ufuk Akcigit, Michael Peters: w21905
Firm dynamics in poor countries show striking differences to those of rich countries. While few firms indeed experience growth as they age, most firms are simply stagnant in that they neither exit nor expand. We interpret this fact as a lack of selection, whereby producers with little growth potential survive because innovative entrepreneurs do not expand enough to force them out of the market. To explain these differences, we develop a theory whereby firms require managerial inputs for production and countries differ in their managerial delegation possibilities. If delegation of managerial tasks to outside managers is difficult in poor countries, entrepreneurs are forced to rely on their own time to supply managerial services. Improvements in the efficiency of delegation will raise the re...
|April 2013||Innovation, Reallocation and Growth|
with Daron Acemoglu, Ufuk Akcigit, Nicholas Bloom, William R. Kerr: w18993
We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A new and central economic force is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using US Census micro data on firm-level output, R&D and patenting. The model provides a good fit to the dynamics of firm entry and exit, output and R&D. Taxing the continued operation of incumbents can lead to sizable gains (of the order of 1.4% improvement in welfare) by encouraging exit of less productive firms and freeing up skilled labor to be used for R&D by high-type incumbents. Subsidies to the R&D of incumbents do not achieve this objective because they encourage the survival and expansion of ...
