iii TITLE: APPLYING BAYESIAN ANALYSIS METHOD TO EVALUATE ENVIRONMENTAL, SOCIAL, AND GOVERNANCE TO FOREIGN DIRECT INVESTMENT IN THE ORGANIZATION FOR ECONOMIC COOPERATION AND DEVELOPMENT COUNTRIES: THE ENHANCING ROLE OF TRADE OPENNESS ABSTRACT In the increasingly competitive landscape of attracting FDI, non-economic factors such as ESG standards have gained prominence in both research and policymaking. This thesis investigates the impact of Sovereign ESG on FDI inflows in 38 OECD countries and examines the moderating role of trade openness. Using data from the WDI for the period 2002-2023, the study applies PCA to construct a composite ESG index and employs Bayesian analysis to estimate the Sovereign ESG and FDI inflows relationship. The results indicate that Sovereign ESG has a negative effect on FDI inflows, while mineral rents also exert a negative influence, consistent with the “resource curse” hypothesis. In contrast, inflation, tariff, and biodiversity are positively associated with FDI inflows. Trade openness directly promotes investment flows, but the interaction between Sovereign ESG and trade openness shows a negative effect, suggesting that deeper integration into global trade may reduce the positive role of Sovereign ESG in attracting capital. These findings enrich the empirical literature on Sovereign ESG and FDI inflows while offering policy implications for OECD economies: Enhancing ESG standards, improving resource governance, and balancing trade strategies are all essential for fostering sustainable development alongside investment attractiveness. Keywords: Bayesian analysis, ESG, FDI, OECD, trade openness.

1 CHAPTER 1. INTRODUCTION 1.1. Background In today’s globally integrated economy, countries aiming for development not only depend on their own resources but also need to engage with the global market. This integration allows them to maximize the combination of external and internal resources to foster economic growth. Attracting FDI has become a common strategy among countries in the context of international integration. The benefits that FDI brings to a country’s socio-economic development, particular for developing nations, are significant, and the efforts to attract such investment have yielded positive outcomes. However, as the economy undergoes substantial changes, the growing demand for investment capital can lead to several negative consequences (Latsamy, 2024). World foreign direct investment inflows 3,50 3,00 2,50 2,00 1,50 1,00 Percentage of GDP 0,50 0,00 Year World Figure 1.1. World foreign direct investment inflows (Source: UNCTAD) According to the UNCTAD report from 2024, FDI flows in 2023 totaled $1.33 trillion, a decrease of 2 percent compared to 2022. This overall figure was influenced by significant fluctuations in a few European conduit economies. When excluding these conduits, global inflows actually declined by more than 10 percent.

2 Figure 1.2. FDI value and growth rates categorized by income groups and regions (Source: UNCTAD) FDI inflows to developing economies, which had shown resilience in recent years, dropped by 7 percent in 2023. In contrast, flows to developed economies (The member countries of the OECD – other than Chile, Colombia, Costa Rica, Mexico and Türkiye), excluding conduits, fell by 15 percent. This downturn was primarily attributed to corporate financial restructuring, partly driven by initiatives to implement a global minimum tax targeting large MNEs, alongside a notable decline in the value of cross-border mergers and acquisitions (M&As). M&As, which particularly impact FDI in developed countries, ended 2023 at just over half the value recorded in 2022. International project finance also struggled, with both the member and value of deals decreasing by about a quarter. The main factors behind these declines included tighter financing conditions, investor certainty, volatility in financial markets, and increased regulatory scrutiny of M&As. On a positive note, greenfield project announcements saw a slight increase in both numbers and value. This uptick was primarily driven by increased announcements in manufacturing industries, breaking a decade-long trend of gradual decline in this sector. In developing countries, the number of new projects announced rose by 15 percent; however, in developed countries, new project announcements decreased by 6 percent. The contrasting trends in greenfield projects and international project finance deals highlight the different motivations behind
