Lockdown was used worldwide to mitigate the spread of severe acute respiratory syndrome coronavirus 2 and was the cornerstone non-pharmaceutical intervention of zero-COVID strategies. Many previous impact evaluations of lockdowns are unreliable because lockdowns co-occurred with severe coronavirus disease related health and financial insecurities. This was not the case in Melbourne's 111-day lockdown, which left other Australian jurisdictions unaffected.

Although Australia maintains relatively high standards of health and healthcare, there exists disparity in health outcomes and longevity among different segments of the population. Internationally, there is growing evidence that life expectancy gains are not being shared equally among the rich and the poor. In this paper we examine the evolution of mortality inequality in Australia between 2001 and 2018.

In this paper, we examine how pension eligibility affects the psychological distress levels of older women in Australia by exploiting the exogenous changes in the eligibility ages of the old Age Pension (AP). The unique features of the Australian AP allow us to study the impact of the reform on the non-working, as well as on the working population. The empirical results show that pension eligibility has a modest but consistently beneficial effect on psychological stress levels.

In 2007, Thailand's Civil Servant Medical Benefit Scheme (CSMBS), one of the three main public health insurers, adopted a new payment mechanism for hospital admission. There has been a shift from fee-for-service toward Diagnostic Related Group (DRG)-based payment that transfers financial risk from the government to health care providers. This study investigates the effects of this policy change on hospital admission, frequency of admission, length of stay (LOS), type of hospital admitted, and out-of-pocket (OOP) inpatient medical expenditure.

Worldwide, countries have been restricting work and social activities to counter the emerging public health crisis due to the coronavirus pandemic. These measures have caused dramatic increases in unemployment. Some commentators argue that the "draconian measures" will do more harm than good due to the economic contraction, despite a large literature that finds mortality rates decline during recessions.

This paper explores the effects of experiencing the death of a spouse, relative or close friend on cognitive functioning of Australian elderly. Using rich longitudinal data, we show that experiencing a loss is associated with a modest decline in cognitive function. Our results show that on average the effects are more pronounced for males and the strongest effects are associated with the loss of the spouse or a close friend.

We examined the role of billing processes in health care utilization by exploiting a shift in provider payment from fee-for-service reimbursement towards fee-for-service direct disbursement for outpatient services in Thailand. Specifically, prior to October 2006, affected patients had to pay the full cost of outpatient treatment and subsequently received reimbursement; thereafter, these payments can be sent directly to the providers, without patients having to pay anything upfront. By using nationally representative micro-data and a difference-in-difference methodology, we show that the direct disbursement policy leads to an increase in outpatient utilization among the sick.
