Therefore, this thesis aims to provide new evidence on the impacts of trade and financial openness on financial development, the impact of financial development on economic growth, and the impact of trade openness on environmental quality in 64 developing countries over the period 2003-2017. One major contribution of this thesis for three objectives is the adoption of the regression model based on Bayesian model averaging approach to consider model uncertainty (Raftery et al., 1997; Hoeting et, al., 1999; Chipman et al., 2001; Fragoso et al., 2018). Regarding the impacts of openness on financial development, the thesis demonstrates that the contribution of trade openness to financial development is important in developing economies with better institutions. However, financial openness has an insignificant positive effect on financial development. There is no evidence to support the Rajan and Zingales hypothesis that the simultaneous openness to both trade and capital flows promotes financial development. The findings also indicate that a better institutions environment allows a developing economy to exploit the benefits of openness to financial development. Regarding the impact of financial development on economic growth, the main findings indicate that financial development has a significant U-shaped effect on economic growth, providing new insight concerning the relationship between financial development and economic growth in developing countries. The results also demonstrate that investment to gross domestic product ratio and foreign direct investment have significant positive effects on economic growth, whereas population growth has a significant negative impact on economic growth. xiii With regard to the impact of trade openness on environmental quality, the empirical results reveal that trade openness in developing countries does not cause environmental degradation. Besides trade openness, the findings provide strong evidence in favour of financial openness and renewable energy consumption as two of the most important determinants of environmental quality by reducing carbon dioxide emissions. Meanwhile, inward FDI stock to domestic capital stock and income have harmful effects on environmental quality in the context of developing countries. Keywords: Openness, financial development, economic growth, environmental quality, developing countries, Bayesian model averaging. 1 CHAPTER 1 - INTRODUCTION 1.1. Research problems It is now widely accepted that trade and financial openness constitute potentially important mechanisms for financial development (Rajan and Zingales, 2003; Baltagi et al., 2007, 2009; Chinn and Ito, 2002, 2006; Law and Demetriades, 2006; David et al., 2014; Svaleryd and Vlachos, 2002, 2005; etc.) which in turn can influence economic growth, especially in developing countries (Caporale et al., 2014; Estrada et al., 2010, 2015; Menyah et al., 2014; Calderón and Liu, 2003; Bittencourt, 2012; Law and Singh, 2014; Rioja and Valev, 2004a, b). Regarding trade openness, it could be one of the most crucial factors explaining environmental quality (Antweiler et al., 2001; Cole and Elliott, 2003; Managi et al., 2009; Atici, 2009, 2012; Baek et al., 2009; Nasir and Rehman, 2011; Shahbaz et al., 2016; Mutascu, 2018). Although there have been numerous investigations attempting to understand financial development, growth and environmental quality research, the majority of studies only utilised methodologies for panel data basing on traditional statistical inference (Gries et al., 2009; Chinn & Ito, 2002; Cecchetti & Kharroubi, 2012; Estrada et al., 2015; Zhang et al., 2012; Ergungor, 2008; Adu et al., 2013; Frankel & Rose, 2005; Antweiler et al., 2001; Cole & Elliott, 2003; Le et al., 2016). The standard statistical approaches ignore model uncertainty, leading to over-confident inferences, “all-or-nothing” constraint, and omitted variable bias that generalize poorly (Raftery, 1993; Raftery et al., 1997, 2005; Hoeting et al., 1999; Chipman et al., 2001; Fragoso et al., 2018, Hinne et al., 2020). Moreover, the competitive theories and empirical studies have remarkably emerged from the literature on financial development, growth and environmental quality determinants, which poses a significant challenge for development economics. Therefore, Bayesian model averaging (BMA) is a tailor- made approach to deal with the model uncertainty that surrounds the large set of candidate regressors. In this thesis, the adoption of BMA proposed by several seminal 2 works, such as Raftery (1993), Raftery et al. (2005), Raftery et al. (1997), and Hoeting et al. (1999), can make significant contributions at bridge the methodology. Besides, previous findings are not conclusive; hence financial development, economic growth, and environmental quality studies have been highly controversial in development economics. The impacts of openness on financial development Regarding the impacts of openness on financial development, the seminal work of Rajan and Zingales (2003) argue that, for genuine financial development, a combined liberalisation of both trade and capital accounts are a necessary condition (the simultaneous openness henceforth); this is the simultaneous openness hypothesis on financial development. According to Rajan and Zingales (2003), interest groups (incumbents) are often against financial development because it generates stronger competition that erodes their rents. They argue that contemporaneous opening of both the trade and capital flows will reduce incumbents’ powers, hence enhancing financial development. Moreover, through new opportunities, trade and financial openness might bring sufficient new profi
