Financial development, corruption and informality in MENA

Reducing the extent of informality in the Middle East and North Africa would help to promote economic growth. This column reports evidence on how corruption and financial development influence the size of the informal economy in countries across the region. The efficiency of the financial sector in MENA economies reduces the corruption incentive for firms to seek to join and stay in the formal sector.

In a nutshell

The effects of financial development and corruption on the shadow economy are contingent on the level of development in a country; indeed, these two factors play a significant role in nurturing informality in the middle- and low-income countries of the MENA region.

A set of policies targeting informality requires a multi-dimensional approach that considers the complex interactions between financial development, corruption and other factors such as trade openness and economic diversification.

By prioritising policies that promote formal economic engagement and transparency, MENA countries can effectively reduce the size of their informal economies and foster sustainable and inclusive economic growth.

Informality is widely recognised as a key factor limiting growth in developing countries (La Porta and Shleifer, 2014). Estimates suggest that the share of the informal sector in the Middle East and North Africa over the last three decades has ranged between 20% and 40% of GDP (see Figure 1). Achieving a big shift of informal businesses into formality would help to release the region from the poverty and middle income traps, enhance inclusive growth, open further and wider opportunities for younger generations and boost tax revenues.

Our study (Haffoudhi and Guizani, 2023) explores disparities in the extent of informality among MENA countries by examining how corruption and financial development influence the size of the shadow economy (also known as the informal economy, the underground economy or the unofficial economy).

Research on the relationship between corruption and the shadow economy has not as yet reached a consensus. While some authors argue that corruption and the shadow economy are complements, others suggest that the two are substitutes, notably in high-income countries.

Moreover, research on financial development and the shadow economy highlights a complex nexus between them. While a large body of this work reveals that the development of the banking sector is associated with a smaller size of the unofficial economy, some studies emphasise the potential existence of a non-linear relationship between them (Njangang et al, 2020).

More specifically, the effects of financial development on the shadow economy depend on several factors, such as the level of development and the size of remittances, as in the case of North African countries (Akçay and Karabulutoğlu, 2021). Additionally, many studies have confirmed that as the financial system in a country develops, the propensity to pay bribes fades away (Altunbas and Thornton, 2012; Jha, 2019).

Our study uses data on a sample of 21 countries in the MENA region over the period from 1996 to 2018 to investigate the nature of both the separate and interactive effects of the financial development and corruption on the size of the shadow economy. The innovation in our research is to explore the potential interplay between the development of the financial system and the corruption in shaping informality.

Our analysis reveals a number of insights. First, the econometric findings show that the development of the financial system in the region represents a significant incentive for firms to make the transition from informality to formality.

Second, corruption also provides incentives for entrepreneurs in the region to stay in the formal sector instead of going underground. By functioning as ‘grease for the wheels’ for businesses,smoothing the burden of complex regulation and inefficient public services, corruption inadvertently attracts more informal entrepreneurs to the official economy, For them, paying bribes becomes an opportunity to escape regulatory and judiciary punishment and, at the same time, to benefit from the advantages that the formal sector brings, notably in terms of access to bank funding.

Third, this effect of corruption on the unofficial economy depends on the levels of financial development. In fact, our econometric analysis shows positive and statistically significant coefficients of the interaction between financial development and corruption. This evidence demonstrates that these two variables are substitutes in reducing informal economic activities – that is, the marginal impact of increasing along one dimension is higher when the other dimension is low. Overall, we can assert that the efficiency of the financial sector in MENA economies reduces the corruption incentive (the grease for the wheels effect) for firms to seek to join and stay in the formal sector.

Fourth, the impacts of financial development and corruption on the shadow economy are contingent on the level of development in a country; indeed, these two factors play a significant role in nurturing informality in the group of middle- and low-income countries of the region. Clearly, informal activities in the high-income cohort of countries are derived from factors other than the level of financial development and corruption. For this category of countries, openness to international trade and the low level of diversification of their economies play more significant roles in fuelling underground activities.

Fifth, comparing low corruption countries to high corruption countries, we make the unexpected finding that financial development in the former is associated with larger sizes of the informal economy. This result underlines our theoretical analysis illustrating the ambiguity and complexity of the connection between the development of the financial system and the informal sector.

Sixth, the reducing effects of financial development and corruption on the size of the shadow economy are more important and remarkable in countries with relatively lower levels of financial development.

To conclude, a set of policies targeting informality requires a multi-dimensional approach that considers the complex interactions between financial development, corruption and other factors such as trade openness and economic diversification. Our study shows that to reduce unofficial economic activities to a manageable size, MENA countries need to promote financial sector development to provide incentives for formal economic ventures and implement anti-corruption measures to create a level playing field for businesses.

Additional key measures include unblocking economic potential, fostering transparency and accountability in governance, and enhancing openness to international trade to diversify the economy and mitigate informal practices. By prioritising policies that promote formal economic engagement and transparency, MENA countries can effectively reduce the size of their informal economies and foster sustainable and inclusive economic growth.

Economic roots of early marriage in Iran

Despite the documented harms of being married off before the age of 18, particularly for girls, early marriage remains common in parts of Iran. This column summarises research that sheds light on the economic factors that drive this practice, using unique provincial data to show that poverty, inflation and income inequality are key determinants –while religiosity is not. The findings suggest that economic policies can play a crucial role in reducing the prevalence of child marriage.

Natural disaster literacy in Iran: survey evidence from Tehran

The frequent floods, earthquakes, and heat waves in the Middle East and North Africa underscore the urgent need to assess the region's preparedness for natural disasters. This column summarizes the state of 'natural disaster literacy' in various parts of Tehran, the capital of Iran and one of the most populous metropolitan areas in MENA. Data from a survey conducted in the winter of 2020/21 enabled the development of a disaster literacy index, which helps to identify the city's most vulnerable districts.

Should Arab countries join the WTO’s agreement on government procurement?

Not all members of the World Trade Organization are signatories of the institution’s Agreement on Government Procurement – the GPA. Indeed, although many developing economies are now joining the agreement or at least acquiring observer status, it has long been thought that the costs outweigh the benefits. This column re-evaluates the pros and cons of GPA accession for Arab countries.

EU climate policy: potential effects on the exports of Arab countries

The carbon border adjustment mechanism aims to ensure that Europe’s green objectives are not undermined by the relocation of production to parts of the world with less ambitious climate policies – but it could impose substantial costs on developing countries that export to the European Union. This column examines the potential impact on exporters in the Arab world – and outlines possible policy responses that could mitigate the economic damage.

Climate change threats and how the Arab countries should respond

The Arab region is highly vulnerable to extreme events caused by climate change. This column outlines the threats and explores what can be done to ward off disaster, not least moving away from the extraction of fossil fuels and taking advantage of the opportunities in renewable energy generation. This would both mitigate the potential for further environmental damage and act as a catalyst for more and better jobs, higher incomes and improved social outcomes.

Exchange rate undervaluation: the impact on participation in world trade

Can currency undervaluation influence participation in world trade through global value chains (GVC)? This column reports new evidence on the positive impact of an undervalued real exchange rate on the involvement of a country’s firms in GVCs. Undervaluation acts as an economy-wide industrial policy, supporting the competitiveness of national exports in foreign markets vis-à-vis those of other countries.

Child stunting in Tunisia: an alarming rise

Child stunting in Tunisia seemed to have fallen significantly over the past two decades. But as this column reports, new analysis indicates that the positive trend has now gone dramatically into reverse. Indeed, the evidence is unequivocal: the nutritional health of the country’s youngest citizens is rapidly deteriorating and requires immediate and decisive action.

Green hydrogen production and exports: could MENA countries lead the way?

The Arab region stands at the threshold of a transformative opportunity to become a global leader in green hydrogen production and exports. But as this column explains, achieving this potential will require substantial investments, robust policy frameworks and a commitment to technological innovation.

Freedom: the missing piece in analysis of multidimensional wellbeing

Political philosophy has long emphasised the importance of freedom in shaping a meaningful life, yet it is consistently overlooked in assessments of human wellbeing across multiple dimensions. This column focuses on the freedom to express opinions, noting that it is shaped by both formal laws and informal social dynamics, fluctuating with the changing cultural context, particularly in the age of social media. Data on public opinion in Arab countries over the past decade are revealing about how this key freedom is perceived.
