Growth theory is based on the assumption of exponential total factor productivity (TFP) growth. Across countries and time periods I find that TFP growth is actually linear. Unlike the exponential model, the additive growth model provides useful medium-term forecasts of TFP. It also explains the...

Economists use micro-based and macro-based approaches to assess the effects of health on economic growth. The micro-based approach tends to find smaller effects than the macro-based approach, thus presenting a micro-macro puzzle regarding the economic return on health. We reconcile these two...

We explore the relationships between subjective well-being and income, as seen across individuals within a given country, between countries in a given year, and as a country grows through time. We show that richer individuals in a given country are more satisfied with their lives than are poorer...

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...

This paper analyzes the role of specialized high-skilled labor in the growth of the service sector as a share of the total economy. Empirically, we emphasize that the growth has been driven by the consumption of services. Rather than being driven by low-skill jobs, the importance of...

We study the evolution of market-oriented policies over time and across countries. We consider a model in which own and neighbors' past experiences influence policy choices, through their effect on policymakers' beliefs. We estimate the model using a large panel of countries. We find that there...

The "Easterlin paradox" suggests that there is no link between a society's economic development and its average level of happiness. We re-assess this paradox analyzing multiple rich datasets spanning many decades. Using recent data on a broader array of countries, we establish a clear positive...

I study the allocation of human capital in an economy with production externalities, financial constraints and career choices. Agents choose to become entrepreneurs, workers or financiers. Entrepreneurship has positive externalities, but innovators face borrowing constraints and require the...

Over the past 60 years, the U.S. financial sector has grown from 2.3% to 7.7% of GDP. While the growth in the share of value added has been fairly linear, it hides a dramatic change in the composition of skills and occupations. In the early 1980s, the financial sector started paying higher wages...

We provide a theoretical description of a process that is capable of generating growth and income convergence among economies, and where freer trade has persistent, positive effects on productivity, beyond the standard efficiency gains due to reallocation effects. We add to a standard Ricardian...
