The Rule of Law, Firm Size, and Family Firms
Countries with a weaker rule of law tend to have more family-run firms, which tend to be small and grow slowly.

The macroeconomics of microfinance
We provide a quantitative evaluation of the aggregate and distributional impact of microfinance or credit programs targeted toward small businesses. We find that the redistributive impact of microfinance is stronger in general equilibrium than in partial equilibrium, but the impact on aggregate output and capital is smaller in general equilibrium. Aggregate total factor productivity (TFP) increases with microfinance in general equilibrium but decreases in partial equilibrium. When general equilibrium effects are accounted for, scaling up the microfinance program will have only a small impact ...

Taking Stock of the Evidence on Microfinancial Interventions
We review the empirical evidence on microfinance and asset grants to the ultra poor or microentrepreneurs and use quantitative economic theory to account for this evidence. Properly executed, these interventions can help segments of the population increase their income and consumption, but neither literature gives much reason to believe that such interventions can lead to wide-scale, transformative impacts akin to escaping aggregate poverty traps.

There are two sides to every coin—even to the bitcoin, a virtual currency
Central to Bitcoin is its independence from any institution or government, allowing anyone to engage in a direct transaction at a low cost. So, what exactly is it, and how does it work?

Who Should Work from Home During a Pandemic? The Wage-Infection Trade-off
Shutting down the workplace is an effective means of reducing contagion but can induce large economic losses. We harmonize the American Time Use Survey and O*NET data to construct a measure of infection risk (exposure index) and a measure of the ease with which a job can be performed remotely (work-from-home index) across both industries and occupations. The two indexes are negatively correlated but distinct, so the economic costs of containing a pandemic can be minimized by sending home only those workers that are highly exposed to infection risk but that can perform their jobs easily from ...

Lifetime labor supply and human capital investment
We develop a model of retirement and human capital investment to study the effects of tax and retirement policies. Workers choose the supply of raw labor (career length) and also the human capital embodied in their labor. Our model explains a significant fraction of the US-Europe difference in schooling and retirement. The model predicts that reforms of the European retirement policies modeled after the US can deliver 15?35 percent gains in per-worker output in the long run. Increased human capital investment in and out of school accounts for most of the gains, with relatively small changes ...

Financial markets: an engine for economic growth
Do developed financial markets lead to economic growth or result from it? While some economists argue for the latter, the author maintains that financial markets?despite their shortcomings of late?are an essential ingredient for an economy to grow in the long run.

Why Is the Labor Share Declining?
The fraction of national income accruing to labor (the labor share) had been roughly constant in developed economies for much of the 20th century but has fallen since the 1980s. We review several of the leading explanations in the literature for the declining labor share. We then point to hitherto unexplored dimensions of the data and provide suggestive evidence for a new explanation. In particular, we show that the labor share began a steeper descent in 2000. This more recent break in the labor-share trend coincides with the rapid rise of software investment, which has left a larger impact ...

Big Push in Distorted Economies
Why don't poor countries adopt more productive technologies? Is there a role for policies that coordinate technology adoption? To answer these questions, we develop a quantitative model that features complementarity in firms' technology adoption decisions: The gains from adoption are larger when more firms adopt. When this complementarity is strong, multiple equilibria and hence coordination failures are possible. More importantly, even without equilibrium multiplicity, the model elements responsible for the complementarity can substantially amplify the effect of distortions and policies. ...

Misallocation and Manufacturing TFP in Korea, 1982-2007
The authors apply the analysis of Hsieh and Klenow (2009) to assess the degree of resource misallocation in the Republic of Korea manufacturing sector from 1982 to 2007. They find improvement in the aggregate allocative efficiency during the first decade and a strong reversal after 1992. This pattern reflects the dynamics of the within-industry distortion measures for most industries and is consistent with the evolving systematic relationship between the age/value added of establishments and their measured idiosyncratic distortions over the sample period. Their finding suggests that the ...
