Is informality bad for business?


Formal businesses in developing countries often complain about unfair competition from their peers in the informal sector. Their complaints are often well-founded: Growing formal companies must go through the hurdles of paying taxes and fees, waiting in line for permits, and even facing greater scrutiny from government agencies.

Informal businesses, on the other hand, use minimal, if any, time or resources to comply with those regulations. As a result, they get to sell their goods and services at a lower cost than their formal competitors.

The parallel systems persist, but do formal businesses really suffer?

Impacts of internally displaced persons on formal business

In a new working paper, we explored this hypothesis by examining the large numbers of Internally Displaced Persons (IDPs) during Colombia’s armed conflict in the late 1990s and the 2000s. IDPs increased the size of the informal sector dramatically and were more likely to take informal jobs because they often lacked legal IDs, were more likely to be unskilled, had little-to-no experience in non-agricultural jobs, and many of them were affected by traumatic events that prevented them from taking high-tier formal jobs.

That leaves opportunities in the informal economy, offering cut-rate services with little regulation or oversight.

We find that the IDP inflows had large and negative impacts on formal firms in Colombia. When inflows of IDPs increased by 10 percent, the production of formal firms dropped by 3 percent. In addition, the probability of firm exit increased by 2 percentage points. A back-of-the-envelope calculation suggests that the average formal firm experienced a 6.6 percent annual decrease in its production between 1995 and 2010 because of IDP inflows.

We also document that the negative effects of IDP inflows are concentrated on formal firms operating in sectors where informality is more predominant, and as such may face stronger informal competition. These negative impacts could be explained by different mechanisms:

Integrating IDPs and refugees into labor markets

Fast forward to today, what do these findings mean for current policies?

Take the case, for example, of the growing number of Venezuelan refugees in Latin America. According to the U.N. Refugee Agency (UNHCR), there are over 4 million refugees and migrants from Venezuela worldwide. While they were initially received with open arms, attitudes are changing as the latest waves are more likely to be unskilled and to join the informal sector. Denying them the right to work in the formal economy could push them to take informal jobs and thereby add serious pressures on Latin American formal firms, our results suggest.

More generally, our findings highlight the importance of national policies and international cooperation efforts in facilitating the integration of IDPs and refugees into formal labor markets.

The size of the informal sector is already very large across Latin America. By denying work permits, governments risk making it even larger.

The Future Development blog informs and stimulates debate on key sustainable development issues within and across all countries.

Now hosted by the Center for Sustainable Development, this blog was originally launched in September 2013 by the World Bank and the Brookings Institution in an effort to hold governments more accountable to poor people and offer solutions to the most prominent development challenges. Continuing this goal, Future Development was re-launched in January 2015 at In the ensuing years, the blog’s scope evolved in parallel with ongoing international policy debates and was formally updated in November 2022 to focus on broader challenges of sustainable development around the world.
