2022 The Effects of STEM Summer Programs on College Major, Persistence, and Graduation for Underrepresented High School Students in the United States

The federal government and many individual organizations have invested in programs to support diversity in the STEM pipeline, including STEM summer programs for high school students, but there is little rigorous evidence of their efficacy. We fielded a randomized controlled trial to study a suite of such programs targeted to underrepresented high school students at an elite, technical institution. The STEM summer programs differ in their length (one week, six weeks, or six months) and modality (on-site or online).

2022 (Co-)Working in Close Proximity: Knowledge Spillovers and Social Interactions

We examine the influence of physical proximity on between-startup knowledge spillovers at one of the largest technology co-working hubs in the United States. Relying on the random assignment of office space to the hub's 251 startups, we find that proximity positively influences knowledge spillovers as proxied by the likelihood of adopting an upstream web technology already used by a peer startup.

2022 Closing the Gender Gap in Patenting: Evidence from a Randomized Control Trial at the USPTO

Women are underrepresented in patenting and the gap is not closing quickly. One major roadblock to progress is a dearth of causal evidence on the potential effectiveness of policies to reduce the gender gap in patenting. Analyzing a randomized control trial at the United States Patent and Trademark Office that was designed to provide additional help to applicants who do not have legal representation, we find heterogeneous causal impacts across gender and technologies on the probability of obtaining patent rights.

2022 Missing Information - Why Don’t More Firms Seek Out Business Advice?

This paper tests whether providing more information on business practices can lead firms to seek out advice and improve their practices. The authors collaborated with a business advice provider in Brazil to implement a randomized experiment with 866 small firms. The treatment groups received different versions of an information sheet that benchmarked business practices to other firms and listed five practices to improve.

2022 The Impact of Soft-Skills Training for Entrepreneurs in Jamaica

A randomized control trial with 945 entrepreneurs in Jamaica shows positive shortterm impacts of soft-skills training on business outcomes. The effects are concentrated among men, and disappear twelve months after the training.

2022 Information Frictions and Firm Take Up of Government Support: A Randomised Controlled Experiment

This paper studies whether informational frictions prevent firms from accessing government support using a randomised controlled trial. We focus on two Portuguese COVID-19 relief programs, providing (i) wage support for workers who are kept on payroll and (ii) credit lines backed by government guarantees. We randomly assign firms to a treatment providing either simplified information about a program, or a combination information and step-by-step application support. We find a significant treatment effect on take up of the wage support program.

2022 Improving Management with Individual and Group-Based Consulting: Results from a Randomized Experiment in Colombia

Differences in management quality are an important contributor to productivity differences across countries. A key question is then how to best improve poor management in developing countries. We test two different approaches to improving management in Colombian auto parts firms. The first uses intensive and expensive one-on-one consulting, while the second draws on agricultural extension approaches to provide consulting to small groups of firms at approximately one-third of the cost of the individual approach.

2022 Behavioral Biases and Under-adoption of Business Practices

The study investigates the role of information constraints and behavioral biases in the under-adoption of key business practices by micro-enterprises in Brazil. We combine a randomized control trial with online surveys to study these questions.

2022 The effect of macroeconomic uncertainty on firm decisions

Using a new survey of firms in New Zealand, we document how exogenous variation in the macroeconomic uncertainty perceived by firms affects their economic decisions. We use randomized information treatments that provide different types of information about the first and/or second moments of future economic growth to generate exogenous changes in the perceived macroeconomic uncertainty of some firms. The effects on their decisions relative to their initial plans as well as relative to an untreated control group are measured in a follow-up survey six months later.

2022 Automation in Small Business Lending Can Reduce Racial Disparities: Evidence from the Paycheck Protection Program

By enabling smaller loans, broader geographic reach, and less human bias in decision-making, process automation may reduce racial disparities in access to financial services. We find evidence for all three channels in a setting where private lenders faced no credit risk but decided who to serve: the Paycheck Protection Program (PPP), which provided loans to small businesses during COVID-19. Black-owned firms disproportionately obtained their PPP loans from fintech lenders, especially in areas with high racial animus.

2022 Gender Specific Project Evaluation and Access to Finance

We seek to understand what is limiting women's access to finance, in particular for highly skilled start-up entrepreneurs. To investigate supply side constraints, we run a lab-in-the-field experiment in which loan officers in Uganda evaluate several business ideas based on real pitch decks from start-ups. We separate biases in idea evaluation from other constraints (such as gender specific differences in the ability to implement a project, or in external constraints that start-up entrepreneurs are facing).

2022 Give Me a Pass: Flexible Credit for Entrepreneurs in Colombia

Microcredit promised business growth for small firms lacking access to banking loans. Although microcredit has reached millions, recent randomized evaluations find limited average business impacts. Critics often blame contract rigidity, specifically the fixed and frequent installments, for the lack of productive risk-taking. But such rigidity may instill borrower discipline. This study partnered with a Colombian lender that offered first-time borrowers a flexible loan that permitted delaying up to three monthly repayments.

2022 Investing with the Government: A Field Experiment in China

We study the demand for government participation in China’s venture capital and private equity market. We conduct a large-scale, non-deceptive field experiment in collaboration with the leading industry service provider, through which we survey both sides of the market: the capital investors and the private firms managing the invested capital by deploying it to high-growth entrepreneurs. Our respondents together account for nearly $1 trillion in assets under management.

2022 Rationalizing entrepreneurs’ forecasts

We analyze, benchmark, and run randomized controlled trials on a panel of 7,463 U.S. entrepreneurs making incentivized sales forecasts. We assess accuracy using a novel administrative dataset obtained in collaboration with a leading US payment processing firm. At baseline, only 13% of entrepreneurs can forecast their firm’s sales in the next three months within 10% of the realized value, with 7.3% of the mean squared error attributable to bias and the remaining 92.7% attributable to noise.

2022 Impact Evaluation of an Intervention on Small and Medium Enterprises in Chile

This impact evaluation aims to measure the effect of a program that combines business training, mentoring, and a large cash transfer on high-potential small and medium businesses in Chile. 250 out of the top 500 firms participating in a business plan competition will be randomly selected to receive all three components of the program, while the remaining firms will receive none of them.

2022 Training, Communications Patterns, and Spillovers Inside Organizations

We study direct productivity changes and spillovers after a randomized training program for the frontline workers in a Colombian government agency. While trained workers improved their individual production, we also find substantial spillovers that affected managers' productivity. We use email data and a survey to explore the mechanisms behind these spillovers and find that managers' increased output arises from reductions in the need to help lower level employees.
