Plain English Summary The COVID-19 crisis had a profound impact on firms. Firms which were more productive pre-crisis fared relatively better, particularly in countries with a more competitive business environment. Using survey data for about 8000 firms, including both small and large firms, in 23 emerging and developing countries in Europe and Cen...

We provide evidence that commercial lenders in Peru suffer leakages in their loan approval process. Leveraging a discontinuity in the loan approval process of a large bank, we find that receiving a loan approval from the bank causes loan applicants to receive offers from other financial institutions as well. Competing lenders captured almost three...

This paper measures the employment effect of a programme in Mexico that granted firms wage subsidies during the recent economic crisis. I use monthly administrative data at the industry level, along with Euclidean distance matching to construct groups of eligible and ineligible durable goods manufacturing industries that display statistically ident...

Innovation policy aims to foster collaborations between science and industry in many countries, but there is little evidence for the effectiveness of such efforts in developing countries. We use regression discontinuity to measure the impact of funding from Poland’s In-Tech program on innovation activities carried out by consortia of firms and rese...

A randomized control trial with 432 small and medium enterprises in Mexico shows positive impact of access to 1 year of management consulting services on total factor productivity and return on assets. Owners also had an increase in “entrepreneurial spirit” (an index that measures entrepreneurial confidence and goal setting). Using Mexican social s...

Using a panel of administrative data and regression discontinuity analysis, this paper examines how the introduction of preferential tax regimes for Georgian micro- and small businesses in 2010 affected formal firm creation and tax compliance. The results show that the new tax regime for micro-businesses increased the number of newly registered fir...

We study the impact of a comprehensive high school financial education program spanning 6 states, 892 schools, and approximately 25,000 students in Brazil through a randomized control trial. The program increased student financial proficiency by a quarter of a standard deviation and raised grade- level passing rates. Short- term financial behaviors...

This paper studies the use of psychometric tests, designed by the Entrepreneurial Finance Lab (EFL), as a tool to screen out high credit risk and potentially increase access to credit for small business owners in Peru. We compare repayment behavior patterns across entrepreneurs who were offered a loan based on the traditional credit-scoring method...

This paper studies the use of psychometric tests, designed by the Entrepreneurial Finance Lab (EFL), as a tool to screen out high credit risk and potentially increase access to credit for small business owners in Peru. We use administrative data covering the period from June 2011 to April 2014 to compare debt accrual and repayment behavior patterns...

The majority of microenterprises in most developing countries remain informal despite more than a decade of reforms aimed at making it easier and cheaper for them to formalize. This paper summarizes the evidence on the effects of entry reforms and related policy actions to promote firm formalization. Most of these policies result in only a modest i...

This paper provides new evidence on the impact of access to finance on poverty. It highlights an important channel through which access affects poverty—the labor market. The paper exploits the opening of Banco Azteca in Mexico, a unique “natural experiment” in which over 800 bank branches opened almost simultaneously in preexisting Elektra stores....

We conduct randomized experiments around a large-scale financial literacy course in Mexico City to understand the reasons for low take-up among a general population, and to measure the impact of this financial education course. Our results suggest that reputational, logistical, and specific forms of behavioral constraints are not the main reasons f...

This paper explores the empirical relationship between bank competition, bank concentration, and the emergence of credit reporting institutions. The authors find that countries with lower entry barriers into the banking market (that is, a greater threat of competition) are less likely to have a credit bureau, presumably because banks are less willi...

We conducted a field experiment in Belo Horizonte, Brazil to test which government actions work to encourage informal firms to register. We find zero or negative impacts of information and free cost treatments and a significant but small increase in formalization from inspections. The local average treatment effect estimates of the inspection impac...

Take-up of voluntary financial education programs is typically extremely low. This paper reports on randomized experiments around a large financial literacy course offered in Mexico City to understand the reasons for low take-up, and to measure the impact of financial education. It documents that the general public displays little interest in such...

Efforts to make it easier for firms to register formally are the most common form of business regulatory reform over the past decade. While there is evidence that large reforms have resulted in some increases in registration rates, recent experimental evidence suggests very few informal firms choose to register when given information about how to d...

Experts report on the latest research on extending access to financial services to the 2.5 billion adults around the world who lack it. About 2.5 billion adults, just over half the world's adult population, lack bank accounts. If we are to realize the goal of extending banking and other financial services to this vast “unbanked” population, we need...

Levels of development vary widely within countries in the Americas. We argue that part of this variation has its roots in the colonial era, when colonizers engaged in different economic activities in different regions of a country. We present evidence consistent with the view that “bad” activities (those that depended heavily on labor exploitation)...

We test whether managerial human capital has a first order effect on the performance and growth of small enterprises in emerging markets. In a randomized control trial in Puebla, Mexico, we randomly assigned 150 out of 432 small and medium size enterprises to receive subsidized consulting services, while the remaining 267 enterprises served as a co...

Different views have been put forward to explain why most firms in developing countries operate informally. One view argues that informal-business owners are entrepreneurs who do not register their firm because the regulation process is too complex. Another argues that informal-business owners are people trying to make a living while searching for...

This article starts with a summary of the microfinance movement, its growth and outreach. In addition, it outlines the various microfinance lending models and institutional designs. Next it discusses microfinance for entrepreneurs in detail, including a discussion of the challenges in measuring the impact of microfinance. Microfinance supporters of...

This paper examines the effects of providing financial services to low-income individuals on entrepreneurial activity, employment, and the income levels of men and women. We exploit cross-time and cross-municipality variation in the opening of Banco Azteca in Mexico to measure these effects with a difference-in-difference strategy. This bank opened...

Identifying the determinants of entrepreneurship is an important research and policy goal, especially in emerging market economies where lack of capital and supporting infrastructure often imposes stringent constraints on business growth. This paper studies the impact of a comprehensive business and financial literacy program on firm outcomes of yo...

What capital is missing in developing countries? We put forward “managerial capital,” which is distinct from human capital, as a key missing form of capital in developing countries. And it has also been curiously missing in the research on growth and development. We argue in this paper that lack of managerial capital has broad implications for firm...

This paper examines the effects of providing financial services to low-income individuals on entrepreneurial activity, employment, and income. The analysis exploits cross-time and cross-municipality variation in the opening of Banco Azteca in Mexico to measure these effects with a difference-in-difference strategy. Banco Azteca opened more than 800...

We present new evidence on the randomization methods used in existing experiments, and new simulations comparing these methods. We find that many papers do not describe the randomization in detail, implying that better reporting is needed. Our simulations suggest that in samples of 300 or more, the different methods perform similarly. However, for...

This paper examines the characteristics and performance of female-owned firms in Latin America. Data from firm surveys show that female-owned firms tend to be smaller than male-owned firms in terms of employees, sales, costs, and physical capital. Female-owned firms also have lower profits than male-owned firms, but for larger firms this difference...

Levels of economic development vary widely within countries in the Americas. We argue that part of this variation has its roots in the colonial era. Colonizers engaged in different economic activities in different regions of a country, depending on local conditions. Some activities, such as mining and sugar cultivation, were “bad” in the sense that...

Levels of economic development vary widely within countries in the Americas. We argue that this variation can be explained by differences in institutions which in turn have their roots in the colonial era. Colonizers engaged in different economic activities in different regions of a country, depending on the local conditions and the supply of nativ...

This thesis is a collection of three essays on entry regulation, institutions, and development.Chapter 1 examines the effect of a business registration reform in Mexico on economic activity. This reform made registration procedures less complex and was implemented in different municipalities at different points in time, allowing for identification....

This paper studies the effect of business registration regulation on economic activity using micro-level data. The identification strategy exploits the fact that a recent business registration reform in Mexico was introduced in different municipalities at different points in time. Using panel data from the Mexican employment survey, I find that the...

I investigate the effects of voucher-school competition on educational outcomes. In my model, parents decide between public schools and voucher schools (that is, private schools that receive a voucher for each enrolled student). The public schools have no direct incentive to produce quality, beyond meeting a minimum enroll-ment level and voucher sc...

The ninth in our series of impact notes examines the impact of a large-scale banking expansion in Mexico, showing that simply increasing access to finance can have important economic effects. Financial development is strongly associated with economic growth across countries, and several recent studies have found a positive correlation between acces...
