1.1.1 Practical background For recent decades, shadow economy, investment from abroad, institutional quality and income inequality have attracted a great deal of attention in development economics because all of them relate to economic growth. Both of foreign direct investment (FDI) and institutional quality (IQ) are considered important determinants of economic growth and development (Borensztein, Gregorio, & Lee, 1998; NairReichert & Weinhold, 2001; Rodrik, Subramanian, & Trebbi, 2004; Acemoglu, Johnson, & Robinson, 2005; Hansen & Rand, 2006; Varsakelis, 2006; and Kandil, 2009). While the official economy is closely related to the shadow economy (Schneider & Bajada, 2003; Vo & Pham, 2014). Moreover, economic growth is associated with income inequality (Kuznets, 1955; Barro, 2000). Especially, these variables and their relationships become worth studying in the context of Asia for its rising thorny features, such as high flow of FDI but low institutional quality, large shadow economy and rising income inequality. First, global foreign direct investment has significantly grown since the 1970s, reached $1.76 trillion in 2015, fell 13% in 2016 ($1.52 trillion) and recovered in 2017; especially, developing Asia is now the largest recipient and accounts for almost onethird of total FDI inflows (UNCTAD, 2017). It is seen as the result of Asian countries in effort to attract FDI for economic development by adopting an open door policy, governance changes & institutional innovation (Haggard, 2004; Lee, 2002). However, the positive impact of FDI on economic growth depends on the institutional quality in the host countries (Brahim & Rachdi, 2014; Jude & Levieuge, 2017). It is also Asia‘s specific concern, especially when there are many countries might be stuck in middle income trap in the region and deficient institutional quality is one of the main causes (Dollar, 2015). Figure 1.1 describes the institutional quality by 5 components (including Voice and Accountability, Political Stability and Absence of Violence, Government Effectiveness, Regulatory Quality, and Rule of Law) in 19 Asian countries 1 on average from 2002-2015. The scale of measurement ranks from -2.5 (lowest quality) to 2.5 (highest quality). In general, the institutional quality in Asian countries is low. The improvement has been seen but it is a slow progress. FDI has flowed into Asian countries in great amounts, but institutional quality is still problematic in the region. Whether institutional quality really helps attracting FDI and FDI in its turn helps improving institutional quality. Does this bidirectional relationship exist in Asian countries?
