This research identifies factors that explain the liquidity of commercial banks in the Vietnam banking system from 2010 to 2015. Using the OLS regression method for analysis, it was found that:(1) the interbank market helps commercial banks improve their liquidity;(2) the larger the loan size, the higher the liquidity risk;(3) good credit risk management has a positive impact on liquidity risk management; and(4) long-term interest rate is negatively related to the liquidity of commercial banks.The research also makes recommendations on liquidity risk management policies to banks and policy-makers from the Government and the State Bank of Vietnam.

Purpose This paper aims to investigate the nonlinear relationship between corporate social performance (CSP) and economic policy uncertainty (EPU). Design/methodology/approach This paper uses panel regression techniques to examine a sample consisting of UK-listed non-financial companies during 2000–2018. Findings The authors found that EPU increases corporate social responsibility which suggests that firms become more socially proactive during the period of heightened EPU. Such countermeasure enhances CSP and is likely a part of a competitive strategy and an insurance mechanism to protect firms against uncertainty in long-term. Further analysis shows a nonlinear relationship between the two factors, suggesting that in a heightened uncertain business environment, the insurance benefit generated by CSP is neutralised by the corresponding cost and, therefore, the positive relationship between EPU and CSP reverses. Originality/value This paper is the first to find a nonlinear relationship between CSP and EPU, indicating that too much uncertainty in macroeconomic policies deteriorates the benefits of CSP to the point that the CSP – EPU relationship becomes negative. The results suggest that policy uncertainty has both the bright side and the dark side where too many cooks eventually spoil the broth.
