Entry Motivations Shape Preferences for Social Protection Among Platform Workers
Using a discrete-choice experiment with nearly 800 taxi, delivery, and cleaning platform workers in Germany, Italy, and Poland, we estimate how much workers value paid sick leave and paid holidays. Workers who entered platform work out of economic necessity (the "pushed") value such social protection provision much more than those attracted by its flexibility and advantages (the "pulled").

Refugees and Entrepreneurship: Evidence from Ukrainians in Poland
We study the impact of the inflow of Ukrainian refugees into Poland following Russia's 2022 invasion on business creation. Ukrainians accounted for 7% of new firm registrations in 2022–23. We find that 10 extra Ukrainian registrations lead to 3.4 to 5.3 more Polish firms.

The Role of Job Task Routinization in Shaping Return Intentions: Evidence from Ukrainian War Refugees in Poland
Measuring worker-level job tasks of Ukrainian war refugees in Poland, we find substantial task routinization, namely performing more routine-intensive jobs in Poland after displacement than in Ukraine before the full-scale war. People who experience a greater task routinization after finding a job in Poland in 2022 were more likely to revise their plans towards return to Ukraine and staying in Poland by 2023.

Workers’ exposure to AI across development stages
This paper develops a task-adjusted, country-specific measure of workers’ exposure to artificial intelligence (AI) in 108 countries, covering approx. 89% of global employment. Accounting for within-occupation task differences significantly amplifies the development gradient in AI exposure. We attribute these differences primarily to cross-country differences in ICT use intensity, followed by occupational composition, human capital and globalisation-related firm characteristics.

How to Avoid Another Yellow Vests movement? Evaluating Preferences for a Carbon Tax with a Discrete Choice Experiment
Using a a discrete choice experiment with 10,000 people in Poland, we examine public preferences for policies to achieve energy security and climate change mitigation goals in the context of the energy crisis caused by Russia’s invasion of Ukraine. We find a strong aversion to carbon tax, only slightly mitigated by redistribution. Income, trust, and age shape preferences for climate and energy policies, and for redistribution mechanisms.

Occupational exposure to contagion and the spread of COVID-19 in Europe
Social contacts are a key transmission channel of infectious diseases spread by the respiratory or close-contact route, such as COVID-19. There is no evidence, however, on the question of whether the nature and the organisation of work affect the spread of COVID-19 in different countries. I have developed a methodology to measure country-specific levels of occupational exposure to contagion driven by social contacts. I combined six indicators based on Occupation Information Network (O*NET) and the European Working Condition Survey (EWCS) data.
