The threats of the coronavirus have shifted the workplace of many people from office to home and also made e-commerce the primary medium for purchases. While these changes were made in an effort to mitigate contagion, there are no studies, to the best of our knowledge, that address if teleworking and e-commerce culture prior to the pandemic influenced the dispersion of the virus. In our study we examine whether pre-existing teleworking practices and e-commerce activity have played an important role in the COVID-19 dispersion in Europe. Based on a set of data from all European countries, the present study employs the Philips & Sul methodology to explore corona convergence patterns. Our findings suggest that pre-existing e-commerce activity and teleworking practices had little to no effect in reducing the initial opportunities of individuals to contract the virus leading to the conclusion that other social interactions must have played a more important role.

This paper examines the relationship between world crude oil markets following the introduction of Shanghai crude oil futures from the perspective of network connectedness based on the vector autoregressive model. The connectedness measurement method proposed by Diebold and Yilmaz (Econ J 119(534):158-171, 2009, Int J Forecast 28(1):57-66, 2012. 10.1016/j.ijforecast.2011.02.006, J Econom 182(1):119-134, 2014. 10.1016/j.jeconom.2014.04.012) is adopted to study a time-varying interdependence relationship. The empirical results show that the world crude oil markets exhibit a high degree of integration from both returns and volatility; however, the direction and magnitude contributed by each market varies significantly. Specifically, the West Texas Intermediate futures and Brent spot and futures markets were found to have the highest contributions to the world oil market over the entire sample period and take leading roles, whereas Dubai futures market was found to be the most important receiver, and has received the most spillover from other markets and passed it throughout the system. Shanghai crude oil futures is not yet highly connected with other markets. Moreover, heterogeneous changes in the direction, intensity, and persistence of the spillover were observed across markets after the outbreak of the COVID-19 pandemic in 2020. This study reveals the integration level of Shanghai crude oil futures and the dynamics of linkages between regional crude oil markets, which is of great significance for market participants, policymakers, and future researchers.

The study attempts to add significant outcomes to the U.S. food prices literature by performing a dynamic regression model and a frequency domain causality test to explore the causality and relationships between U.S. food prices, energy prices, economic policy uncertainty, and the value of the U.S. dollar. It is shown that dollar price negatively affects the food price index at both high and low volatility periods. Furthermore, it is presented that there is a permanent long-run causal relationship running from the dollar index to the food price index. The results indicated that there is a significant positive relationship between the energy price index and the food price index. Moreover, energy is found to be a long-run and permanent cause of the food price index. The effect of uncertainty has not been sufficiently explored in the food pricing field, the outcome of this study reveals that uncertainty increases the food price index at high volatility times. Besides, uncertainty is shown to be the long-run and permanent cause of the food price index.

The three sustainability pillars of social, environment and economy were initially introduced by the United Nations in 2002, addressing major global sustainability issues including economic problems, income inequality, environmental pollution and social shortcomings. Comparing East Asia & Pacific with North America, there is a growing concern over economic, political and even social competition as a result of recent development and industrialization that is taking place in Asian countries. This might lead to an unhealthy conflict that favors regional independency as opposed to the current globalization and trade facilitation trend. As a result, this study aims to assess the effects of development in three main pillars of sustainability (social, environment and economy) in the East Asia and Pacific on that of North America and vice versa. To estimate this interactive or spillover effects of sustainable development (or sustainability elasticities), our research employs Econometric methodologies including Simultaneous Equations System, Vector AutoRegressive (VAR) and Granger Causality approaches during 1971-2016. The results show that most of the sustainability elasticities are positive between and inside the two regions, supporting the synergetic character of the sustainability spillover effects and confirming constructive role of globalization and openness in the sustainability progress. Based on the results, this research suggests policy-makers to follow cooperative and flow-based governance rather than the placed-based or regional independent thinking that supports integrated sustainable development benefiting not only the two parties but also the overall global sustainability.

This paper offers an analysis of the supply of Airbnb accommodation in Rome, one of the main tourist destinations in the world, the third-largest city in Europe, by the number of Airbnb listings. The aim is to focus on the recent spatial trend of Airbnb listings, including the period of the COVID-19 pandemic, and highlight the main housing and socioeconomic characteristics of the neighbourhoods associated with a strong presence of Airbnb listings. The study is developed with quantitative methods and spatial regression (spatial lag and spatial error using OLS as a benchmark), based on data collected from the Inside Airbnb and Tomslee websites. In the period 2014-2019, the listing trend in Rome has been increasing in absolute numbers. After the start of the pandemic, the trend became negative, and the decline of Airbnb offerings is more substantial for shared accommodation. Airbnb supply is related to the distance from the city centre, the average income of the area, empty apartments, singles and the share of foreign residents coming from high-income countries. A signal of spatial diffusion of Airbnb listings emerges in the coastal area, even if they are increasingly concentrated in the historic centre, where there is a monoculture of short-term renting.
