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.

Price versus quantity measures to deal with pollution and congestion in urban areas: A political economy approach
Pollution and congestion in urban areas are serious externalities that can be mitigated through the adoption of either price- or quantity-based mechanisms. While price restrictions are occasionally applied, quantity constraints based on car vintage are becoming increasingly popular. Our model provides a comprehensive analysis that explains this prevalence of quantity over price schemes. We also elucidate some other stylized facts observed in urban areas applying traffic restrictions, such as the implementation of hybrid price-and-quantity systems, the use of trial periods and commitments to invest in public transit to enhance the acceptability of urban tolls, and the concentration of quantity restrictions in high-income cities.

Presence of tourists and perceived safety from COVID-19 among local bus users
Since the start of the COVID-19 pandemic, public transport has been signalled as a potential contagion hot-spot, leading to a generalised decrease in its use. In this study, we explore how the presence of tourists influences the configuration of the perceived safety related to the transmission of COVID-19 on public transport daily users. Our results show how the presence of tourists in buses influences negatively the perception of safety of local users. However, this influence is highly related with their prior perception of their risk to contagion.

How has COVID-19 affected the performance of green investment funds?
This paper adopts quantile regressions to scrutinize the dynamics of green investment funds in relation to the outbreak of the COVID-19 pandemic. We use data on three of the largest green investment funds (BNP PARIBAS Funds Climate Impact, Nordea Global Climate & Environment, and AMUNDI Funds Global Ecology ESG), whose proceeds finance environmental-focused projects.

Long-memory and volatility spillovers across petroleum futures
We analyze volatility connectedness across petroleum markets, making two significant contributions to the literature. First, we relax the questionable assumptions on the persistence of volatilities in previous studies by accounting for the long-memory possibility, which is more in accordance with the empirical evidence. To do so, we rely on the connectedness framework of Diebold and Yilmaz (2012;2014), but, unlike previous literature, we employ a fractionally integrated VAR.

What hampers or increases the R&D intensity of firms?
Many studies have analysed the determinants of firms' internal R&D expenditure-see, for example, (Montresor and Vezzani, 2015) or (Coad, 2019). Such studies typically find the heterogeneity of firm level R&D investment (Coad et al., 2020), the incidence of non-observable characteristics on the R&D effort (Cohen and Klepper, 1992), and the non-homogenous nature of R&D activity (Czarnitzki and Hottenrott 2011a; Barge-Gil and López 2014). The topic is important since R&D investment expands a country's technological frontier. Thus, we need to understand how the distribution of R&D investments is influenced by different firms' characteristics and by the economic cycle.
