Why doesn’t capital flow into fast-growing countries? In this paper, we provide a quantitative framework incorporating heterogeneous producers and underdeveloped domestic financial markets to study the joint dynamics of total factor productivity (TFP) and capital flows. When an unexpected once-and-for-all reform eliminates non-financial distortions and liberalizes capital flows, the TFP of our model economy rises gradually and capital flows out of it. The rise in TFP reflects efficient reallocation of capital and talent, a process drawn out by frictions in domestic financial markets. The concurrent capital outflows are driven by the positive response of domestic saving to higher returns, and by the sluggish response of domestic investment to the higher TFP—the latter being another ramifica...

Income differences across countries primarily reflect differences in total factor productivity (TFP). More disaggregated data show that the TFP gap between rich and poor countries varies systematically across industrial sectors of the economy: Poor countries are particularly unproductive in tradable and investment goods sectors. In this paper, we develop a quantitatively-oriented framework to explain such cross-country patterns in aggregate and sectoral TFP. We start by documenting that an important distinction between sectors is their average establishment size. For example, establishments in tradable and investment goods sectors operate at much larger scales than those in the non-tradable sector. In our model, sectors with larger scales of operation have more financing needs, and are hen...
