From 2021 to 2024, net public support for the euro remained remarkably stable and reached historically high values across the EA-19. Perceptions of inflation in the national and personal economic situation had no significant effect on public support for the euro during the post-pandemic inflation surge and subsequent decline from 2021 to 2023. These findings contrast with those for the before-crisis and crisis periods, in which inflation and inflation perceptions had a significant negative impact on public support for the euro. Similar to public support for the euro, trust in the institutions that govern the Euro was also not affected by the post-pandemic inflation surge. 2026-01-01T00:00:00Z https://hdl.handle.net/10419/296467.3 Title: Evolution and Determinants of Generalized Trust – The Global Evidence over 41 Years Authors: Roth, Felix Abstract: By constructing a unique international database on generalized trust covering 142 countries worldwide for 41 years from 1980 to 2020, this paper finds a pronounced intertemporal variation of generalized trust over time in a majority of countries across the globe. When analyzing the time series patterns over the last four decades, a divergence in generalized trust between OECD and non-OECD economies is found. While the OECD economies saw an increase in generalized trust, the non-OECD economies faced a decline. European Coordinated Market Economies drive the increase in trust in OECD economies. Their increase in trust is driven by rising income, higher college graduation rates, and an ageing society. Asian and African economies drive the decline in non-OECD economies. Their decline in trust is driven by a rejuvenating society and country-specific shocks, such as the autocratization of the political system or severe famine. The decline in trust in those countries is responsible for the overall global decline. 2026-01-01T00:00:00Z https://hdl.handle.net/10419/305221.2 Title: Trust and Growth: The Global Evidence over 40 Years Authors: Roth, Felix Abstract: This paper analyzes the intertemporal variation of trust on economic growth. Constructing a unique global country panel dataset and applying a system-generalized method of moments (SYSGMM) estimation approach to a sample of 75 global economies over a 40-year time span (1980-2019), this paper finds evidence of a curvilinear (inverted U-shape) relationship between trust and growth.3 Only a minority of global economies can attain a position close to or above the optimum threshold for trust and growth. Most economies, in fact, fall well below that threshold, and for them, it is incumbent to consider trust-building measures in order to achieve higher growth. In countries that are close to the optimum threshold, however, such policies can likely be neglected. In fact, in countries where trust levels exceed the optimum, an increase in trust might even hamper growth. 2026-01-01T00:00:00Z https://hdl.handle.net/10419/344079 Title: Measurement Discrepancies in Intangible Capital: Evidence from Five Advanced Economies Authors: Nonnis, Alberto; Roth, Felix; Bounfour, Ahmed Abstract: The growing importance of intangible capital poses major challenges for its measurement in national accounts. This paper asks whether estimates of intangible investment are comparable across countries, examining France, Germany, Italy, the UK and the US. We assess reported estimates against independent, internationally harmonized sources: occupational data on ICT specialists and managers, wage data from the Structure of Earnings Survey, R&D composition data from ANBERD, and firm-level investment data from the EIB Investment Survey (EIBIS). We find that the largest cross-country gaps, particularly in software and organizational capital, are difficult to reconcile with the underlying distribution of inputs. France and Germany employ similar shares of ICT specialists yet report a threefold difference in software investment relative to value added, while the higher organizational capital recorded in France is not matched by its managerial wage structure. A micro-informed recalibration suggests that these measurement differences can materially affect cross-country productivity comparisons. 2026-01-01T00:00:00Z
