Economic development in Latin America has trailed most other world regions over the past four decades despite its relatively high initial development and school attainment levels. This puzzle can be resolved by considering the actual learning as expressed in tests of cognitive skills, on which...

We investigate whether a causal interpretation of the robust association between cognitive skills and economic growth is appropriate and whether cross-country evidence supports a case for the economic benefits of effective school policy. We develop a new common metric that allows tracking...

Although many U.S. state policies presume that human capital is important for state economic development, there is little research linking better education to state incomes. In a complement to international studies of income differences, we investigate the extent to which quality-adjusted...

We propose a unified growth theory to investigate the mechanics generating the economic and demographic transition, and the role of mortality differences for comparative development. The framework can replicate the quantitative patterns in historical time series data and in contemporaneous...

Intangible knowledge capital (IKC) - technology produced by workers but not embodied in them - can offset the "middle income trap" as China exhausts the benefits of international technology transfer. IKC is productivity-enhancing among Chinese enterprises - more so in domestically owned than in...

We propose a unified growth theory to investigate the mechanics generating the economic and demographic transition, and the role of mortality differences for comparative development. The framework can replicate the quantitative patterns in historical time series data and in contemporaneous...

This paper provides a unified theory of the economic and demographic transition. Individuals make optimal decisions about fertility, education of their children and the type and intensity of the investments in their own education. These decisions are affected by different dimensions of mortality...

In the aftermath of World War II, the world's economies exhibited very different rates of economic recovery. We provide evidence that those countries that caught up the most with the U.S. in the postwar period are those that also saw an acceleration in the speed of adoption of new technologies....

We study a dynamic general equilibrium model where innovation takes the form of the introduction new goods, whose production requires skilled workers. Innovation is followed by a costly process of standardization, whereby these new goods are adapted to be produced using unskilled labor. Our...

This paper revisits and critically reevaluates the widely-accepted modernization hypothesis which claims that per capita income causes the creation and the consolidation of democracy. We argue that existing studies find support for this hypothesis because they fail to control for the presence of...
