Labour market effects of robots: evidence from Turkey

4107

Evidence from developed countries on the impact of automation on labour markets suggests that there can be negative effects on manufacturing jobs, but also mechanisms for workers to move into the services sector. But this narrative may not apply in developing economies. This column reports new evidence from Turkey on the effects of robots on labour displacement and job reallocation.

In a nutshell

For most developed countries, studies of the impact of automation consistently find negative effects on the labour market; but the net impact of robots on employment and wage changes may be different in developing countries, as well as across industries, skill levels and age groups.

Districts in Turkey with existing manufacturing firms tend to expand employment in response to a robot shock; but robotisation negatively affects the total employment of incumbent workers.

Automation seems to have a complementary relationship with those who keep their employment in the affected firms; this evidence is more apparent when these workers are employed in different occupations within the same firm.

How does automation affect labour markets? Does it simply reduce employment – or does it have additional outcomes, such as creating new job opportunities, increasing productivity, forcing workers to seek employment in different sectors or even to change occupations? There has been a considerable amount of economic research on these important questions.

For example, Graetz and Michaels (2018) demonstrate that between 1993 and 2007, an increase in robot density contributed to a 0.37 percentage point rise in annual GDP growth and a 0.36 percentage point increase in labour productivity growth. Their study finds no significant impact of industrial robots on overall employment levels, although it does report some evidence that they displace low-skilled workers and, to a lesser extent, middle-skilled workers.

Acemoglu and Restrepo (2020) find that in the United States, each additional robot per 1,000 workers is associated with a 0.2% decrease in the employment-to-population ratio and a 0.42% reduction in wages. Equivalently, the addition of one new robot results in a reduction in employment of approximately 3.3 workers. The employment impact of robots is predominantly negative in routine manual and blue-collar jobs, because these workers perform tasks that are easily automated by robots, leading to their displacement.

Conversely, Dauth et al (2018) report no overall employment losses in Germany. But their study differentiates between the manufacturing and services sectors, and while it finds a slightly negative impact on manufacturing employment, there is a positive effect on the services sector. This suggests a potential reallocation mechanism from manufacturing to services.

For most developed countries, studies of the impact of automation consistently find negative effects, either affecting the overall labour market or the manufacturing sector and blue-collar workers specifically. But some studies report positive employment effects. For example, analysing data from EU countries, Klenert et al (2022) find that the use of robots is associated with an increase in manufacturing employment.

Providing evidence from a developing country context, Cali et al (2022) explore the effects of robotisation in Indonesian manufacturing industries and find employment gains. Such studies highlight a mechanism where increased productivity leads to greater scale and higher labour demand. Tuhkuri (2022) finds similar results and explains that in Finland, the positive impact of robotisation on employment is due to firms adopting automation being more likely to focus on making new products rather than displacing labour.

Our new research investigates the relationship between robot adoption and labour market outcomes in Turkey, using novel employer-employee data that includes firm-specific information such as production, wages, trade and worker details provided by the Enterprise Information System of the Ministry of Industry and Technology of Turkey, along with data from the International Federation of Robotics database (Aytun et al, 2023).

Our study analyses labour market outcomes in relation to variations in robot exposure at the district and worker level by considering how sectors and occupation have been affected.

The evolution of robot adoption over recent years

Figure 1 compares the total number of robots per 1,000 workers among selected leading countries and the EU. There is a general upward trend for all, but considerable variations between countries. South Korea experienced a sharp increase in robot penetration per 1,000 workers after 2010, achieving the highest rate of robot adoption. In contrast, Turkey has the lowest penetration rate and has seen only a slight increase during the same period.

Figure 2 illustrates the robot exposure index developed by Acemoglu and Restrepo (2020). The figure demonstrates that the level of exposure closely mirrors the industrialisation levels of districts in Turkey. Western regions tend to have higher employment in manufacturing industries, while eastern regions are more focused on agriculture and services.

Given that the robot industry is primarily concentrated in the automotive and electronics sectors, this specialisation is directly reflected in the exposure index. The Marmara region in the northwest, along with Aksaray and Kirikkale – highlighted as the boldest regions in central Turkey – are prime examples of this trend.

Robots and the workplace

Developing countries often exhibit inefficiencies in their production processes. This indicates the potential for average productivity gains from using robots to generate demand for more workers.

We first test this hypothesis by analysing data from firms operational since 2014, finding that districts with existing firms tend to expand employment in response to a robot shock. But null effects of robot exposure are also found.

Second, we look at how workers in the manufacturing industry adjust their employment and wages when they are exposed to robots. Our results reveal that robotisation negatively affects the total employment of incumbent workers.

This effect is mainly for workers who stay at their original workplace. In other words, the likelihood of keeping the same employment in a non-manufacturing industry reduces when incumbents face exposure to robots. Staying at the original firm and manufacturing industry is also negatively affected by robotisation. But the earnings of the former group are improved in industries with higher robot exposure.

This finding confirms that automation has a complementary relationship with those keeping their employment in the original firm. This evidence is more apparent when these workers are employed in different occupations within the same firm.

Since unemployment rates in Jordan are higher among young people and women than other groups, unemployment is commonly characterised as a youth and gender issue. However, the majority of the country’s unemployed are adults and men. This suggests that unemployment is primarily a macroeconomic issue challenge for the entire labour market. The appropriate response therefore is coordinated fiscal, monetary, structural and institutional policies, while more targeted measures can still benefit specific groups.

Tunisia’s energy transition: the key role of small businesses

Micro, small and medium-sized enterprises (MSMEs) play a critical role in Tunisia’s economy, contributing significantly to GDP and employment. As this column explains, they are also essential for advancing the country’s ambitions to make a successful transition from reliance on fossil fuels to more widespread use of renewable energy sources. A fair distribution of the transition’s benefits across all regions and communities will secure a future where MSMEs thrive as leaders in a prosperous, inclusive and sustainable Tunisia.

The hidden potential of Jordan’s small firms for driving a green transition

For Jordan, a green transition represents an enormous transformative opportunity. But a decade-long increase in the use of renewable energy has not freed the country of its economic woes. This column explores the currently underused yet potentially powerful force of micro, small and medium-sized enterprises – and proposes policies that could improve the investment climate and clear legislative and regulatory barriers.

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.
