Diaspora tourism primarily refers to various population groups, including migrants, foreign workers, political refugees, ethnic and religious minorities and overseas communities living away from their ancestral homeland for various reasons. Throughout history, people have been forced to leave their original homeland due to various factors ranging from economic crises to natural and human-made tragedies, including war. The 24 February 2022 unjustified and unproved Russia's war of aggression against Ukraine, which started on the heels of the two-year COVID-19 pandemic, has resulted in massive and terrible consequences for many domains of political, economic and social life. The Russian invasion of Ukraine has generated the largest historical migration flows at a scale unforeseen in Europe since World War II. Since Russia invaded Ukraine, at least 12 million people have been displaced from their homes, according to the United Nations. The unprecedented influx of the Ukrainian people raises concerns about future developments, issues and challenges associated with Ukrainians' presence in other countries, particularly neighbouring ones. Therefore, this chapter analyses the possibility of diaspora tourism for Ukrainians shortly by utilising a critical approach when the situation stabilises in Ukraine. To begin with, this chapter first explains diaspora tourism with its definition and characteristics. Furthermore, it reviews the literature on the Russia–Ukraine war and its impact on Ukrainian tourism. In conclusion, it discusses the new Ukrainian diaspora wave soon.

The authors study the valuation effect of corporate diversification in the initial phase of the COVID-19 pandemic in 2020 in Europe.

Applying a cross-sectional regression model to a sample of public companies headquartered in the European Union, the authors investigate the existence of and the change in a diversification discount between 2018 and 2020. By applying the Excess Q methodology, the authors make an industry adjustment of diversified companies to measure the value effect of corporate diversification.

The authors find an economically and statistically significant diversification discount that increases from an average Excess Q of −0.05 in 2019 to −0.10 in 2020. The diversified companies' inferior fundamental financial performance in 2020 accompanies the discount. The results deviate from those of previous research, which mostly show a decrease in the diversification discount in economic crises, and thereby, shed doubt on whether diversification provides insurance against pandemic-induced adverse value effects.

The study distinguishes the role of corporate diversification during recessionary periods by establishing that the valuation effect of diversification depends on the nature of the crisis. The analysis incorporates criticism of previous studies concerning a biased methodology and uniform data source by applying the Excess Q methodology and using FactSet industry segment data.
