Abstract: The authors study the effects of regulation on economic growth and the relative size of the informal sector in a large sample of industrial and developing countries. Along with firm dynamics, informality is an important channel through which regulation affects macroeconomic performance and economic growth in particular. The authors conclude that a heavier regulatory burden-particularly in product and labor markets-reduces growth and induces informality. These effects are, however, mitigated as the overall institutional framework improves.

This survey assembles recent theoretical and empirical advances in the literature on economic informality and analyzes the causes and costs of informality in developed and developing economies. Using recent evidence, the survey discusses the nature and roots of informal economic activity across countries, distinguishing between informality as the result of exclusion and exit. The survey provides an extensive review of recent international experience with policies aimed at reducing informality, in particular, policies that facilitate the formalization process, create a framework for the transition from informality to formality, lend support to newly created firms, reduce or eliminate inconsistencies across regulation and government agencies, increase information flows, and increase enforcement.

A large percentage of workers and firms operate in the informal economy, outside the line of sight of governments in emerging market and developing economies. This may hold back the recovery in these economies from the deep recessions caused by the COVID-19 pandemic--unless governments adopt a broad set of policies to address the challenges of widespread informality. This study is the first comprehensive analysis of the extent of informality and its implications for a durable economic recovery and for long-term development. It finds that pervasive informality is associated with significantly weaker economic outcomes--including lower government resources to combat recessions, lower per capita incomes, greater poverty, less financial development, and weaker investment and productivity.

The paper relies on a rich firm-level data set on transition economies to examine the role of informality as an important channel through which regulatory and other policy constraints affect firm growth. We find that firms reduce their formal operations with a higher tax and regulatory burden, but increase it with better enforcement quality. In terms of firm growth, we find a differential impact of regulatory burden and enforcement quality on formal and informal firms. In particular, we find that growth in formal firms is negatively affected by both tax and financing constraints, while these constraints are insignificant for growth in informal firms. Moreover, formal firm growth improves with better enforcement as measured by fair and impartial courts, while informal firm growth is constrained by organized crime, pointing to their inability to take full advantage of the legal and judicial systems. Finally, when we look at country-wide institutions, we find that higher regulatory burden reduces firm growth. An interactive term between a country-wide measure of the rule of law and a proxy for formality suggests that better enforcement quality dampens the relatively weaker growth in formal firms.

The Global Informal Workforce is a fresh look at the informal economy around the world and its impact on the macroeconomy. The book covers interactions between the informal economy, labor and product markets, gender equality, fiscal institutions and outcomes, social protection, and financial inclusion. Informality is a widespread and persistent phenomenon that affects how fast economies can grow, develop, and provide decent economic opportunities for their populations. The COVID-19 pandemic has helped to uncover the vulnerabilities of the informal workforce.
