Different economies at different times use different institutional arrangements to constrain the people entrusted with allocating the economy's capital and other resources. Comparative financial histories show these corporate governance regimes to be largely stable through time, but capable of...

In a cross-section of countries, government regulation is strongly negatively correlated with social capital. We document this correlation, and present a model explaining it. In the model, distrust creates public demand for regulation, while regulation in turn discourages social capital...

We use a micro dataset that collects information across individuals, countries, and time to investigate the determinants of entrepreneurial activity in thirty-seven developed and developing nations. We focus both on individual characteristics and on countries' regulatory differences. We show...

In the last decade, economists have produced a considerable body of research suggesting that the historical origin of a country's laws is highly correlated with a broad range of its legal rules and regulations, as well as with economic outcomes. We summarize this evidence and attempt a unified...

Does democracy promote economic development? We review recent attempts to address this question, which exploit the within-country variation associated with historical transitions in and out of democracy. The answer is positive, but depends -- in a subtle way -- on the details of democratic...

The challenge of mitigating climate change has focused recent attention on basic scientific research feeding into the development of new energy technologies (Popp, 2017). Energy innovation tends to consist of a series of partially overlapping processes involving: (1) the production of scientific...

Key factors in modeling a pandemic and guiding policy-making include mortality rates associated with infections; the ability of government policies, medical systems, and society to adapt to the changing dynamics of a pandemic; and institutional and demographic characteristics affecting citizens'...

Economists devote too much attention to international flows of goods and services and not enough to international flows of ideas. Traditional trade flows are an imperfect substitute for flows of the underlying ideas. The simplest textbook trade model shows that a welfare-enhancing move toward...
