Identity and inequality misperceptions, demographic determinants and efficacy of corrective measures.

By conducting two waves of large-scale surveys in the United Kingdom and Germany, we investigate the determinants of identity and inequality misperceptions. We first show that people substantially overestimate the share of immigrants, Muslims, people under the poverty line, and the income share of the richest. Moreover, women, lower-income, and lower-educated respondents generally have higher misperceptions.

Exploring the hidden impact of the Covid-19 pandemic: The role of urbanization.

We examine the role of residential environments (urban/rural) in understanding the impact of the COVID-19 pandemic and the restrictions in nationwide movement on several socio-economic attitudes. We conducted large-scale surveys in four European countries (France, Germany, Spain, and the United Kingdom) before and after nationwide lockdowns were implemented. We investigate how the pandemic affected: (i) economic (economic insecurity), (ii) political (trust in domestic and international institutions), and (iii) social attitudes (loneliness), by controlling for the degree of urbanization, obtained from the geocodes of the survey respondents.

Exploring consistency between stated and revealed preferences for the plastic bag ban policy in Chile.

This paper exploits individual-level data before the implementation of a national policy to understand the factors driving avoidance of plastic consumption and explore potential inconsistencies between revealed and stated preferences for a plastic bag ban policy. We estimate a bivariate ordered probit model that allows us to account for a potential correlation between these types of preferences. The data reveals that while 71% of respondents take a reusable bag for shopping, only 58% of the sample state to strongly agree with prohibiting plastic bags.

Novel sustainable metallic powder production process with water used as milling medium.

Today, Fe-Al intermetallic compounds are receiving a great interest from the mechanical, aerospace, and biomedical industries. A novel production process for Fe-Al intermetallic powders based on the generation of metallic tapes by rapid solidification and disintegration by water vapor was proposed. In this research work, a comparison is made between the energy required to manufacture of Fe-Al powder using the aforementioned process and one of the most commonly used manufacturing processes within the industry such as mechanical alloying.
