-1- ABSTRACT This dissertation presents essays regarding the relationship between financial wealth and happiness sentiment. Essay I (Chapter 3) investigates the relationship between global wealth and happiness in terms of return and volatility spillovers. Essay I finds that wealth influences happiness positively and happiness mitigates the volatility of wealth. Essay II (Chapter 4) investigates the nexus between global stock markets and precious metals under Covid-19 and happiness perspectives.

Essay II finds evidence that happiness could explain interactions among financial markets in the context of global volatility. Essay III (Chapter 5) investigates the connection between the global economic policy uncertainty and happiness sentiment. Essay III finds that happiness co-moves with uncertainty, and therefore we can use these two factors to supervise daily economic and social volatilities. Essay IV (Chapter 6) investigates the relation between financial technology (Fintech) and happiness sentiment.

Essay IV finds that the development of the Fintech era may be challenged by its impact on happiness. Essay V (Chapter 7) extends the relationship between financial wealth and happiness sentiment in terms of language-based communications via social networks. Essay V affirms the robustness of Essay I for specific countries including Australia, Canada, the United Kingdom, and the United States of America. Essay VI (Chapter 8) seeks the relationship between happiness and the daily performance of solar energy firms.

Essay VI finds that the solar energy development was challenged by the happiness goal before the Covid-19 pandemic and the two variables positively interact to each other after the outbreak. This clarifies the linkage between happiness and solar energy in the global volatility context. Empirical findings from this dissertation states that happiness shall be the more favorable goal of human beings. The multidisciplinary approach of this dissertation generates the connection between financial economics and social sciences.

This dissertation also reflects current trends such as the digital era, the post-pandemic context, and the pursuit of sustainable development goals. In accordance with this dissertation, relevant parties can refer to happiness as a measure for stable economic growth accompanying social and environmental issues. Background and motivations What is the meaning of life? – we have been seeking answers to this question. Finding the objectives of life is one of key missions throughout various fields such as science, philosophy, and religions.

For human beings, the meaning of life could be understood as the pursuit of goals and the sense of fulfillment (Reker & Wong, 1988). In support, the meaning of life contains coherence, purpose, and significance (Martela & Steger, 2016). Beyond reflecting quality (Wong, 2011), the meaning of life includes purpose, understanding, responsibility, and enjoyment (Wong, 2012). In connection, we have been seeking the meaning of life on personal, organizational, national, and global levels.

At the national level, the United States Declaration of Independence of 1776 expresses happiness as a guiding ideal, which is represented by the universal right to the pursuit of happiness. In 2015, the United Nations General Assembly set 17 global Sustainable Development Goals associated with the meaning of life. Consequently, financial wealth and happiness are considered tremendous factors for the meaning of life. Henceforth, understanding the relationship between wealth and happiness allows us to clarify the meaning of life.

There have been studies the relationship between wealth and happiness. Frey and Stutzer (2018) indicate that richer nations tend to be happier than poorer nations, but this fact diminishes with wealth. Hagerty and Veenhoven (2003) and Stevenson and Wolfers (2008) find the logarithmic relation between national wealth and happiness, that is, the same percentual increase in the gross national product generates the same increase in happiness for wealthy countries as for poor countries. Layard (2006) and Blanchflower and Oswald (2008) find the determinants of happiness such as national and personal income, employment, economic security, freedom, and development.

There is also evidence on economic consequences of happiness. Piekałkiewicz (2017) finds that happiness increases productivity, predicts future income, and affects labor market performance. These preliminary backgrounds motivate this dissertation to evaluate the relationship between financial wealth and happiness. Research context The making of this dissertation is driven by prominent global contexts, those are, the digital era, impacts of the Covid-19 pandemic, and the pursuit of sustainability.

Thus, this dissertation shall reflect these research contexts as follows: First, the digital era is an inevitable trend which comes along the fourth industrial revolution. This context facilitates to assess financial wealth and happiness sentiment thanks to the high-frequency data. Accordingly, we shall apply this trend to construct suitable methodological frameworks for this dissertation. Second, the Covid-19 outbreak has been causing enormous damages for the world under various aspects, and financial economics is not an exception (Goodell, 2020).

Following an unprecedented crisis as caused by the pandemic, the world is threatened by volatility, uncertainty, complexity, and ambiguity. Therefore, this dissertation is supposed to capture the relationship between financial wealth and happiness under impacts of the Covid-19 pandemic. Third, the pursuit of sustainable development goals. Indeed, sustainability facilitates economies to pursue stable growth along with the harmony in environmental, social, and governance factors (Hák, et al.

When the global economy is influenced by the Covid-19 outbreak, sustainability is the key for both physical health (McBride, et al., 2019) and mental health (Frey & Stutzer, 2018) in terms of happiness. Hence, this dissertation shall capture the sustainability objective. Research objectives As motivated by the research context as described in Section 1.2, this dissertation is supposed to capture following objectives: ▪ Objective I: Evaluating the relationship between global wealth and happiness. ▪ Objective II: Investigating the relationship between global stock markets and precious metals under Covid-19 and happiness perspectives.

Research questions Equivalent to objectives as above presented in Section 1.
