VIETNAMESE COMMERCIAL BANKS Abstract The effect of economic freedom on the economy’s well-being has been widely documented However, it is absent from the literature of empirical evidence about effect of economic freedom on the banking sector This study employs the overall economic freedom index and the index’s components which are derived from Heritage Foundation to examine their effect on Vietnamese commercial bank’s effieciency In first procedure, we obtain efficiency scores of 39 banks in Viet Nam using Data Envelopment Analysis (DEA), over the period 2010-2018 with 299 observations Then second step, the efficiency scores estimated from DEA method will be regressed on economic freedom indexes, applying truncated regression model combined with bootstrapped confidence intervals while controlling for bank specific characteristics Additionally, we carry out a sensitive analysis using a fractional logit estimator as a robustness check We find strong evidence supporting that far greater economic freedom positively impacts the efficiency of banks in Vietnamese banking sector However, the influence of different economic freedom counterparts on efficiency banking sector is not as uniform as economic freedom overall index such as the higher the degree of property rights, business freedom and freedom from corruption, the better the bank’s performance while negative effects of financial freedom on bank efficiency Besides, the empirical findings also show the positive relationship between capitalization and bank efficiency as well as credit risk and bank efficiency Keywords: Banks, economic freedom, bank efficiency, DEA, truncated regression bootstrap, Viet Nam CHAPTER 1: INTRODUCTION Efficiency is the most important aim of most business including banks, and bank efficiency is a widely discussed topic because of its vital roles in creating a stable and profitable banking sector then impact on economic growth in each country As a perspective that individual’s liberty to pursue its own economic goals will lead to efficient outcomes is as instinctive as the economics theory itself, we have seen that most countries trying to close to economic freedom However, most of studies recently just focus on the relationship between economic freedom (EF) and economic growth, less studies have been carried about effect of economic freedom on banking sector, which is one of the most important financial intermediary playing an important role in providing funding sources for economic growth (Ferreira,2015) EF plays a vital role for the banking sector’s development which categorizes of priority for developing nations and improving efficient banking system in a globalized economy Theoretically argued, EF helps to motivate the environment leading to efficiency financial system’s establishment or being innovative ideas and producing capacities, but the relationship between EF and financial activities still remains vague (Terpilih, 2010) For example, one of component in economic freedom is financial freedom, and the effect of financial freedom (FF) in emerging markets of financial markets is not easily determined as it relies on kind of reform and conditions of financial constrains in the market (Ağca et al., 2007) As a study from Kose et al., (2003), the influence of FF and integration on banking sector and economic growth is hard to determine because it could rely on the governance’s quality and institutions They points that the integration in developing countries is lack of experience, and government could create higher uncertainty shocks to banking sector resulting in lower efficiency Lou et al., (2016) find that the openness with high level leads to shrink of bank performance due to the lack of technologies, skills, the high level of competition and knowledge Higher freedom and openness also lead to the higher dependence on each others and fragility of banking sectors in the world such as credit risk, economic and information shock (Anginer and Demirguc-Kunt,2014), which can affect bank efficiency ( BE) On the other hand, Asharf (2017) finds that freedom increases the bank’s development levels by decreasing cost and bank credit risk The author also finds that freedom helps to remove barriers of trading and stimulate lending diversification which creates more bank credit demand and banks’ chances to growth Reducing restrictions in banking activities due to FF provides more potential chances to improve BE and profitability (Chen, 2009) Banks tend to have higher profitability, efficiency in countries that have high economic and freedom (Tennant and Sutherland 2014) A study from Ahamed (2017) also shows that foreign Banks’s entry following freedom policies will improve the host country’s banking system because of the “technology spillover” effects which positively impact on the financial institution’s performance In Viet Nam, particularly this time, the Association of Southeast Asian Nations (ASEAN) banking system has been preparation for the multilateral- liberalization before of the year 2020 and this is basing on the ASEAN Banking Integration Framework (ABIF) in 2014 Therefore, we expect Vietnamese banking system to achieve higher liberalization, freedom and integration level in 2020 This keys on that the importance to understand the impact of EF on BE to have appropriate actions for the aim of maintaining stable and efficient banking system for economic development in the long term This study follows this spirit by examining the impact of economic freedom on the efficiency of Vietnamese commercial banks during the period of 2010 to 2018 1.1 Research objectives - This study measures commercial bank’s efficiency in Viet Nam during the period of 2010-2018 - This study
