Better roads improve regional economies: evidence from Turkey

Paving dirt roads and building highway networks have unsurprisingly been shown to produce substantial economic gains, but what is the impact on domestic trade from improving existing road networks? Using spatially disaggregated data on major capacity upgrades of existing road networks and domestic transactions in Turkey, this column, originally published at VoxEU, estimates a large positive impact of reduced travel times on trade and regional employment, and long-run aggregate real income gains of 2-3%.

Tackling tax evasion: how an obscure statistical law can help

Benford’s law – which suggests that the leading digits in various types of numerical data are not uniformly distributed – can be used to detect tax evasion in international trade. This column reports an application to imports data and an unexpected trade policy change in Turkey, the results of which reveal an increase in evasion after a doubling of the tax on imports that use external financing. Based on such analysis, tax authorities could decide where to channel resources in their fight against evasion.

Gaining competitiveness through trade credit: evidence from Turkey

The removal of the Multi-Fibre Arrangement quotas that governed global trade in textiles and clothing until the end of 2004 led to a big rise in competition from China for some Turkish exporters to the European Union. This VoxEU column reports evidence that Turkish exporters affected by an increase in competitive pressures responded both by lowering their prices and by extending the trade credit they offered to importers.

Highways to growth: the impact of road upgrades on Turkish trade

Investment in transport infrastructure can improve a country’s growth prospects by facilitating trade. This column reports the findings of research on the impact of a major programme of road upgrades in Turkey from the early 2000s, which converted many two-lane undivided roads into dual carriageways. Trade both within the country and with other countries has benefited significantly from these improvements.

Global value chains and sustainable development

What is the role of exchange rate undervaluation in promoting participation in global value chains by firms in developing countries? What is the impact of the stringency of national environmental regulations on firms’ GVC participation? And how do firms’ political connections affect their participation in GVCs? These questions will be explored for the MENA region at a special session of the ERF annual conference, which takes place in Cairo in April 2025.

Adoption of decentralised solar energy: lessons from Palestinian households

The experience of Palestinian households offers a compelling case study of behavioural adaptation to energy poverty via solar water heater adoption. This column highlights the key barriers to solar energy adoption in terms of both the socio-economic status and dwellings of potential users. Policy-makers need to address these barriers to ensure a just and equitable transition, particularly for households in conflict-affected areas across the MENA region.

Migration, human capital and labour markets in MENA

Migration is a longstanding and integral part of the MENA region’s economic and social fabric, with profound implications for labour markets and human capital development. To harness the potential of migration for promoting economic and social development, policy-makers must aim to deliver mutual benefits for origin countries, host countries and migrants. Such a triple-win strategy requires better data, investment in return migration, skill partnerships, reduced remittance costs and sustained support for host countries.

Shifting gears: how the private sector can be an engine of growth in MENA

Businesses are a key source of productivity growth, innovation and jobs. But in the Middle East and North Africa, the private sector is not dynamic and the region has a long history of low growth. This column summarises a new report explaining how a brighter future for MENA’s private sector is within reach if governments rethink their role and firms harness talent effectively.
