The objective of this paper was to examine the impact of tax policy on social development in Vietnam. In particular, tax policy was measured through the ratio of the government’s tax revenue to gross domestic product - GDP (TAX), and social development is measured through unemployment (UNE). The research data were collected from the General Department of Taxation of Vietnam and the World Bank. We used the Autoregressive Distributed Lag (ARDL) Model to analyze time series data in the period 1990-2017. The paper achieved great success in finding the first empirical evidence of the negative impact of tax policy on unemployment in Vietnam in the long term. In addition, we found a statistically significant impact of domestic savings and domestic investment on unemployment in the both short and long term. This shows that tax policy plays an important role for unemployment as well as social development in Vietnam.

This paper analyzes the causal relationship between the banking system development and the real estate market in Vietnam from 2004:Q3 to 2018:Q4, with the use of the autoregressive distributed lag (ARDL) model as the analysis method. In Vietnam, there is no empirical study on this issue. Therefore, the paper is the first empirical evidence for the relationship between the banking system development and the real estate market in Vietnam. The research results show that the banking system development (measured through the domestic credit to the private sector) and the real estate market had a positive causal relationship in both short and long terms. In addition, the paper found a statistically significant impact of the global financial crisis on the banking system development and the real estate market in Vietnam, which is a new discovery compared with previous studies.
