Average monotonic cooperative games with nontransferable utility
A non-negative transferable utility (TU) game is average monotonic if there exists a non-negative vector according to which the relative worth is not decreasing when enlarging the coalition. We generalize this definition to the nontransferable utility (NTU) case.

The key roles of renewable energy and economic growth in disaggregated environmental degradation
This paper investigates the validity of the environmental Kuznets curve (EKC) hypothesis for the G7 group of countries through the ecological footprint and its components (namely built-up land, carbon, cropland, fishing grounds, forest land, and grazing land). Most previous contributions rely on CO2 emissions as a measure of environmental damage, whereas using disaggregated ecological footprint allows us to consider resource consumption and waste generation compared to nature's resource generation and waste absorption.

Connectedness between emerging stock markets, gold, cryptocurrencies, DeFi and NFT
This paper examines the dynamic connectedness between Gulf countries and BRICS stocks markets with a sample of cryptocurrencies, as well as two newly developed digital assets, namely NFT and DeFi, and gold. Our analysis is based on wavelet coherence, which is a suitable methodology considering the nonlinear dynamics present in data.

Attitudes Towards Single Parents’ Children in Private and State-Dependent Private Schools
In the paper, we study whether private and state-dependent private schools in Catalonia (Spain) are more reluctant to interact with single parents than with heterosexual couples. We conduct a field experiment during the children's pre-registration period.
We create three types of fictitious families (heterosexual couple, single mother, and single father) and send e-mails to schools in which the family structure is made explicit. Our results indicate that schools are more prone to interact with single parents than with heterosexual couples. Hence, this suggests that, if any, there seems to be positive discrimination towards single parents in the schooling context.

Disentangling the impact of economic and health crises on financial markets
This paper explores the impact of different crises on the informational efficiency of financial assets. Unlike previous literature, which study the effect of a single crisis on the informational efficiency in some financial markets, the current paper covers more than two decades of data under different political and economic situations.

Walking through a pandemic: How did utilitarian walking change during COVID-19?
In this study we aim to explore how daily walking for transportation has evolved during partial COVID-19 restrictions, and evaluate whether the traditional and area-level determinants were modified during that period. Using and official travel survey in Southern Catalonia, we observed not only that utilitarian walking frequency and time spent on daily working has decreased, but also did its share compared to other means of transport. During the pandemic, household income and area-level income inequality were no longer predictors of utilitarian walking.

How do coworking spaces coagglomerate with service industries? The tale of three European cities
The paper "How do coworking spaces coagglomerate with service industries? The tale of three European cities" examines the location and agglomeration patterns of coworking spaces (CSs) in Barcelona, Warsaw, and Utrecht. Using K-density functions and density maps, the authors identify how CSs coagglomerate with service sectors and concentrate in core areas of each city. The paper confirms that CSs coagglomerate with Knowledge Intensive Services (KIS) and symbolic knowledge base firms, and that market and high tech KIS with CSs build an urban entrepreneurial ecosystem.

Impact of COVID-19 pandemic on tourist public transportation use and on its determinants
Despite the key importance of public transport for the accessibility, atractiveness, and sustainability of tourist areas, little is known about how the COVID-19 has impacted its use among turists. In response, we compared the likelihood of using public transport among visitors in a Catalan coastal area based on surveys conducted in 2019 and 2020. The pandemic caused a significant decline in tourists'use of public transportation, from 54.5% in 2019 to 34.6% in 2020, and in movility at the destination. Results obtained from a set of bivariate probabilistic models reveal that though most of the traditional determinants of visitors' use of transit remained unaltered, pandemic-related factors were associated with its decline.
