Over the last 20 years, the insurance industry in Vietnam has been rapidly growing with an average annual growth rate of 21%, one of the most active markets in Southeast Asia, raising the question of efficiency to managers, investors, and regulators. This article is one of the first research works using Data Envelopment Analysis combined with the Malmquist index over the period from 2016 to 2020 for 37 insurance firms in Vietnam to investigate the efficiency of this sector. The value-added approach is employed with total equity and operating expenses as inputs, finance income, and gross written premium as outputs. The findings reveal that most of Vietnam's insurance companies are operating quite effectively, and the non-life sector is more efficient than the life sector. There is also a regression in efficiency change, while there is a progression in technological change and total factor productivity change during the period examined. The goal of this research is to give a fundamental understanding of the overall efficiency of insurance firms in Vietnam, and help managers, investors, policyholders, and government agencies make better decisions regarding self-assessment, M&A activities, deregulation... Consequently, the insurance sector could improve in terms of efficiency and develop sustainably over time.

Purpose: many domestic welfare programs use the amount of health insurance premiums as a way of measuring individuals' income levels for administrative convenience. As health insurance reform has been made, we examines the income level is still appropriately measured by the health insurance premiums for the employment success package as one of domestic welfare program. Methodology/Approach: we investigate whether the upper limit of the premiums of the self-employed health insured is appropriate or not after healthcare reform, which currently calculated by multiplying the insurance premium of the employee based insured by the adjustment factor (1.2). Findings: we examined appropriateness of the adjustment factors by comparing the premiums before and after the healthcare reform by utilizing the national health insurance data as well as Korea Welfare panel data. We found that the new value of adjustment factor (1.0~1.1) is smaller than the current one (1.2). Practical Implications: to improve the equity between the employee and the self-employed insured after the health insurance reform, the adjustment factor should be lower.
