Informality and weak competition: A deadly cocktail for growth and equity in emerging Latin America

Why is growth persistently low and so unevenly distributed in emerging Latin America compared to emerging Asia despite a huge potential? Potential growth is ranging around 2-3% in the region. Some refer to dependence on commodities, poor education, weak business environments, or corruption as possible causes. But the question is deeper and more complex. A crucial factor for Latin America is low productivity, often related to a poor use of available resources. Across the region, many workers and significant amounts of capital are stuck in activities that are not efficient. The reasons for this are many, but two important forces stand out: high informality and weak competition. Persistently high levels of informality characterise the LAC region, as shown in Figure 1.

Note: Informality is defined to include i) employees who do not pay health contributions, and ii) self-employed who do not pay social security contributions (Brazil, Chile and Turkey), or whose business is not registered (Argentina, Colombia, Costa Rica, Mexico, Peru and South Africa). Data for Turkey refer to persons aged 15 and more. Data for Argentina refer to selected urban areas (according to the National Statistical Authority (INDEC), LFS series published after the first quarter of 2007 and until the fourth quarter of 2015 must be considered with caution).

High and persistent informality in the region leaves workers more vulnerable and deprives them from social protection, thus contributing to inequality. For example, old age poverty in Colombia is high as low-skilled workers spend much of their working lives in informal employment, without pension contributions (OECD 2019a). In Brazil and Argentina, informal workers retire later than others for the same reason, until they eventually reach the age to benefit from a non-contributory pension (OECD 2019b, 2018a). In Mexico, poverty and informality are highly correlated among regions (OECD 2019c). Informality also tends to keep companies small with often low productivity, as growth would entail high costs of formalisation. Indeed, informal sector productivity in the average LAC country is only between 25% and 75% of total labour productivity, and productivity decreases as informality rises (Loayza 2018). Informality also reduces the tax base for corporate and personal income taxes, reducing the capacity of the public sector to boost productivity and reduce inequality, and this requires a higher tax burden on larger formal companies. 

Weak competition is a second reason behind low productivity and is often reflected in high concentration (Figure 2). Entry barriers can protect existing activities that have little future growth potential, at the cost of new dynamic and productive firms. Weak competition creates rents and lowers the share of wages in value added, worsening income distribution. Higher prices for consumers reduce purchasing power, disproportionally affecting low-income households.

Where high informality and weak competition coincide, as is the case in many Latin American countries, the consequences for both growth and equity can be particularly severe. For emerging Latin America to grow stronger and better share the fruits of growth, dealing with informality and competition should be priority. 

Reducing informality for productivity and equity

The causes of informality are multiple. Informality is often a consequence of high costs of hiring formal workers, both wage and non-wage, especially in relation to labour productivity, given low educational outcomes. 

Labour informality is often caused by rigid labour regulation. High firing costs of workers can discourage formal-sector hiring and promote inequality (Loayza, 2018, OECD 2018b, Heckman and Pages 2000). In Mexico, a labour reform in 2012 reduced hiring and firing costs, introduced different models of contracting, and brought changes to the resolution of labour conflicts. Formal salaried jobs increased in the aftermath (OECD 2019c). Minimum wages can be high compared to productivity or average wages, keeping most workers informal. In Colombia, the minimum wage is close to the median wage and two thirds of workers earn less than that (OECD 2019a). High payroll taxes can also have a detrimental effect on informality rates (Bobba et al. 2018). Antón and Rastaletti (2018) show how lowering employer social security contributions could lead to a substantial increase of labour formalisation. At a minimum, lower employer contributions could be offered temporarily for hiring low-skilled workers that enter the formal sector for the first time (OECD 2017). Lowering payroll taxes in Colombia helped reduce informality after the 2012 reform (Kugler et al. 2017, Morales and Medina 2016, Fernández and Villar 2016, Bernal et al. 2017). While incentives are crucial, better enforcement also needs to be part of any formalisation strategy.

Cumbersome administrative barriers and high taxes can keep companies informal. Latin America stands out in this respect (Figure 3). The tax burden on formal companies is also high compared to the OECD and positively associated to informality rates (Figure 4). To promote formalisation, tax and regulatory systems should be simple. Tax burdens should increase gradually as firms grow, so as not to discourage growth, and keep marginal tax rates as low as possible (Loayza 2018). These characteristics are crucial to encouraging investment and employment in growing and larger companies. 

Many countries in the region have implemented simplified schemes and reduced costs for small taxpayers with the aim of reducing informality. For example, Mexico introduced a special simplified regime for SMEs (Regimén de Incoporación Fiscal, or RIF) in 2014, which induced 1.5 million informal firms to join the tax system (OECD 2018c). In Brazil, a special tax regime for microenterprises (Microemprendedor Invididual, or MEI) reduced the cost of formalisation and contributions to social security as of 2008. This regime helps explain the rising formalisation of the self-employed, including of women (OECD 2012). In Argentina, a simplified tax regime called Monotributo helped formalise self-employed workers. In Colombia, the tax reform in 2018 introduced a new simplified tax scheme (‘Simple’) for small firms, and there are signs of positive impact on firm formalisation during 2019.

At the same time, these regimes have to be designed carefully. When participation thresholds for special SME tax regimes are set too high, the effectiveness for formalisation declines while the fiscal cost and threshold effects rise, as in the case of Brazil’s Simples Nacional (OECD 2018a). At times, simplifying the general tax regime may be preferable to creating exceptions.

Education and skill levels are also linked with informality. Countries with the lowest informality rates tend to have significantly higher levels of human capital (Docquier et al. 2017). It is not a coincidence that the decrease in informality over recent decades in Latin America went hand in hand with steady progress towards universal education. Evidence shows that improvements in education have been an important driving force behind falling informality in Colombia and Brazil (IMF 2018, OECD 2018a).

Increasing competition for productivity and equity

In Latin America, the same complex rules that discourage formal job creation often coincide with overly strict regulations that stifle competition. Competition is affected by how easily firms can enter or exit markets, by the extent of license requirements for starting or expanding a business, and by competitive pressures from imports. Relatively high trade protection adds to this in a number Latin American countries, shielding domestic producers from international competition (OECD 2018a). All of this tends to raise prices for consumers and keep resources in low-productivity activities where informality is widespread, for both workers and firms. 

These circular relationships suggest that it is important for the public sector to take stock of burdens that even well-intended regulations and codes can impose on private activity. Disincentives for firms to formalise will inevitably preclude workers from the benefits of formal jobs, while unnecessary barriers to competition will keep more jobs in activities with limited potential for productivity and wage growth. To foster formal job creation, all parts of a country’s regulatory framework should be simple and clear, promote competition, and facilitate both market entry and exit of firms (Loayza et al. 2005).

Getting there

A comprehensive strategy is needed to deal with both informality and competition. It involves simplifying labour regulations, keeping administrative burdens and license requirements for companies as easy as possible, facilitating market entry, and reducing trade barriers. Bringing more workers and firms into the formal sector would bring about broader social and labour protection, fairer wages, a more even tax burden, and higher potential growth. Many of these policies are politically difficult as they involve dealing with vested interests and require appropriate sequencing – but that is not an excuse for inaction. These reforms should be accompanied with training and other active labour market policies for affected workers, as the informal sector often fulfils the function of absorbing excess labour supply, especially during transitions or economic recessions. Reforms to improve the quality and relevance of education to raise worker productivity and policies that can raise investment and boost firm productivity should be also part of the strategy.
