We study the consequences of a large-scale reassessment of the health and working capacity of disability insurance beneficiaries in Hungary. Leveraging birthday and health cutoffs in the reassessment, we estimate employment responses to the threat of disability benefit loss and the actual termination or reduction of benefits[...]

The use of advanced technologies like artificial intelligence, robotics, or smart devices will go hand in hand with higher productivity, higher product quality, and lower trade costs. Therefore, it can be expected to be positively related to export activities. This paper uses firm level data for manufacturing enterprises from the 27 member countries of the European Union collected in 2025 to shed further light on this issue by investigating the link between the use of advanced technologies and extensive margins of exports[...]

Special economic zone dynamics and firm performance: Evidence from an emerging economy

17th September 2025
KCG Secretary
Authors: Charles Godfred Ackah, Robert Darko Osei, Baah Aye Kusi (Management and Decision Economics 2025, 45(6): 3834–3851)

The empirical literature on Special economic zones (SEZs) has shown that SEZs have become critical policy tools for advancing economic and firm performance, especially in developing economies where financial capital, human capital, technology and technical know-how to drive these performances are in limited supply. While the importance and effects of SEZs cannot be overemphasised and are well documented, particularly in Asia, SEZs' operationalisation, structure and policy practice appear to vary, especially in Ghana and hence a need to examine SEZ effects on firm performance in Ghana.

Big Data Analytics and Exports—Evidence for Manufacturing Firms from 27 EU Countries

KCG Secretary
Authors: Joachim Wagner (Open Economies Review 2025, 36: 825–834)

Divestments by foreign multinationals are an important phenomenon that is largely neglected in the literature. We use firm level panel data from China to estimate the impact of such divestments on the performance of domestic firms in the local economy. To the best of our knowledge, there is no empirical study that has looked at these effects[...]

Trade in services is an important component of international trade and is becoming increasingly more important with growth rates exceeding the rates with which goods trade increases. This is also true in the bilateral U.S. – EU relationship: Trade in services, and especially trade in digitally deliverable services, is a highly important element of the economic relations between the U.S. and the EU. And it is growing much faster than goods trade between the two economies. Despite its importance, trade in services has received much less attention in political and public discussions on the transatlantic trade relationship[...]

There has been an increasing number of Special Economic Zones (SEZ) in Africa since the early 1990s. While there were only around 20 SEZs in the early 1990s in Africa, the number amounted to more than 200 zones all over Africa in 2021. These zones are established to “promote local economic development and reduce regional disparities” (Abagna et al., 2025: 1). In policy debates and academic research, little attention has been paid so far to the impact of SEZ on the households’ welfare development in Africa[...]
