In developing countries, informal firms (those that are not registered with the government) account for about half of all economic activity. We consider three broad views of the role of such firms in economic development. According to the romantic view, these firms would become the engine of...

This paper investigates the determinants of informal economic activity. We present two equilibrium models of informality and test their implications using a survey of 48,000+ small firms in Brazil. We define informality as tax avoidance; firms in the informal sector avoid tax payments but suffer...

Growth and structural transformation of the manufacturing sector in developing countries are generally considered to be the result of the expansion of the "modem" (large-scale) sector relative to the "traditional" (small-scale) sector. Examining the sources of labor productivity growth in...

We establish five facts about the informal economy in developing countries. First, it is huge, reaching about half of the total in the poorest countries. Second, it has extremely low productivity compared to the formal economy: informal firms are typically small, inefficient, and run by poorly...

Tracking individual workers across jobs after Brazil's trade liberalization in the 1990s shows that tariff cuts trigger worker displacements, but neither exporters nor comparative-advantage sectors absorb trade-displaced labor. On the contrary, exporters separate from significantly more and hire...

The distance between small firms and their lenders in the United States is increasing. Not only are firms choosing more distant lenders, they are also communicating with them in more impersonal ways. After documenting these systematic changes, we demonstrate that they do not stem from small...

Was the $278 billion reboot of the $800 billion Paycheck Protection Program (PPP) in early 2021 disbursed equitably to minority communities? This paper provides the first analysis of how PPP funds were disbursed to minority communities in the third and final round of the program, which was...

Using confidential regulatory firm-bank-loan level data from the U.S., we document four new facts about the credit market. First, private SMEs typically utilize all available bank credit which comprises their entire balance sheet debt, compared to large listed firms who can switch between...

We explore the sources of racial disparities in small business lending by studying the $806 billion Paycheck Protection Program (PPP), which was designed to support small business jobs during the COVID-19 pandemic. PPP loans were administered by private lenders but federally guaranteed, largely...

This paper argues that rental market interactions allow small firms to increase their effective scale and mechanize production, even when each individual firm would be too small to invest in expensive machines. We conduct a novel survey of manufacturing firms in Uganda, which uncovers an active...
