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.

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.

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?

Industrial and Occupational Employment Changes During the Great Recession
The U.S. labor market contracted sharply during the Great Recession. The ensuing recovery has been sluggish and by some measures still incomplete. In this paper, we break down aggregate employment during the Recession and the recovery into changes across industries and occupations. There is a clear asymmetric pattern: The contraction is driven by sectors and the recovery by occupations. In particular, the contraction between 2008 and 2010 primarily reflects a steep decline in construction employment, partially mitigated by expansions in the food services, education, and health industries. The ...

Where Are the Workers? From Great Resignation to Quiet Quitting
To better understand the tight post-pandemic labor market in the US, we decompose the decline in aggregate hours worked into extensive margin changes (fewer people working) and intensive margin changes (workers working fewer hours). Although the preexisting trend of lower labor force participation, especially by young men without a bachelor's degree, accounts for some of the decline in aggregate hours, the intensive margin accounts for more than half of the decline between 2019 and 2022. The decline in hours among workers was larger for men than women. Among men, the decline was larger for ...

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. ...

Hit Harder, Recover Slower? Unequal Employment Effects of the COVID-19 Shock
The destructive economic impact of the COVID-19 pandemic was distributed unequally across the population. A worker's gender, race and ethnicity, age, education, industry, and occupation all mattered. We analyze the initial negative effect and its lingering effect through the recovery phase, across demographic and socioeconomic groups. The initial negative impact on employment was larger for women, minorities, the less educated, and the young whether or not we account for the industries and occupations they worked in. By February 2021, however, the differential effects across groups had gotten ...

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 ...

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 ...

The Labor Market Impact of Digital Technologies
We investigate the impact of digital technology on employment patterns in Korea, where firms have rapidly adopted digital technologies such as artificial intelligence (AI), big data, and cloud computing. By exploiting regional variations in technology exposure, we find significant negative effects on female workers, particularly those in non-IT (information technology) services. This contrasts with previous technological disruptions, such as the IT revolution and robotization, which primarily affected male workers in manufacturing. The negative employment effect of AI did not differ across ...
