We construct survey-based measures of routine task intensity (RTI) of jobs consistent with those based on the U.S. O*NET database for workers in 47 countries. We find substantial cross-country differences in the content of work within occupations. We assess the contribution of technology, supply of skills, globalization, and economic structures to the variation of workers’ RTI across countries. Technology is by far the most important factor. Supply of skills is next in importance, especially for workers in high-skilled occupations, while globalization is more important than skills for workers in low-skilled occupations. Occupational structure explains only about one-fifth of cross-country variation in RTI.

We study the labour market transition pathways driven by the coal phase-out in Poland between 1990 and 2050. We apply the concept of branching points to describe the coal transition in the context of structural and labour supply changes and educational upgrading. We show that in the 1990s and 2000s, job opportunities for miners were scarce, as the trajectories of these trends deteriorated their labour market prospects. As these trends have reversed in the 2010s, the future employment outlook of the coal phase-out in Poland is more favourable than in the past. Decarbonisation will lead to a surplus of Polish hard coal mining workers from 2030, yet the projected shortages of workers in other sectors will create opportunities for reallocation.

We evaluate the impact of large minimum wage hikes on employment and wage growth in Poland between 2004 and 2018. We estimate panel data models utilizing the considerable variation in wage levels, and in minimum wage bites, across 73 Polish NUTS 3 regions. We find that minimum wage hikes had a significant positive effect on wage growth and a significant negative effect on employment growth only in regions of Poland that were in the first tercile of the regional wage distribution in 2007. These effects were moderate in size, and appear to be more relevant for wages. Specifically, if the ratio of minimum wage to average wage had remained constant after 2007, by 2018, the average wages in these regions would have been 3.2% lower, while employment would have been 1.2% higher. In the remaining two-thirds of Polish regions, we find no significant effects of minimum wage hikes on average wages or on employment.

We assess the distributional impact of introducing a carbon tax in a small open economy, using the case of Poland. We use a dynamic general equilibrium model with a search mechanism in the labour market, soft-linked to a microsimulation model based on household budget survey data. We find that the distributional effects depend on the recycling of revenues. Using them to reduce labor taxation attenuates the negative effect of carbon tax on GDP and employment but increases inequality compared to a lump-sum transfer to households. This finding highlights the trade-off between efficiency and equity. Our results could be relevant for other countries producing fossil fuels, such as South Africa, Germany, or Australia.
