Many researchers have concluded that longer life expectancies prompt increased investment in education, as a prolonged labor supply raises the rate of return on education. Besides explaining the empirical evidence behind this conclusion (at an absolute level), there is another issue to be discussed: does time spent in studying and working increase proportionally with higher longevity? Building on an extended life-cycle model with an assumption on a more realistic distribution of life cycle mortality rates, this article considers dynamic effects of prolonging longevity on economic development by directly introducing changes in longevity into the economy, which is more preferable than comparative static analysis that relies on changes in relevant parameters. It shows that prolonged life expectancy will cause individuals to increase their time in education but may not warrant rises in labor input. Later we show that higher improvement rate of longevity will also promote economic growth, even if we exclude the mechanism of human capital formation and only consider the growth effects of the higher improvement rate of life expectancy from physical capital investment.

This issue of the International Journal of Healthcare Finance and Economics features eight
articles evaluating different provider payment methods in comparative international perspective, with authors from Hungary, China, Thailand, the US, Switzerland, and Canada. These contributions illustrate how the array of incentives facing providers shapes their interpersonal, clinical, administrative, and investment decisions in ways that profoundly impact the performance of health care systems. Taken as a whole, the articles show that in addition to the specifics of the reimbursement or remuneration scheme for individual providers and provider organizations, other factors matter—including ownership, allocation of control rights (such as in public-private partnerships), and expectation of a bail-out (soft budget constraints). All of these facets of payment and accountability systems shape the quality and efficiency of service delivery.

When one can circle the globe in less than the time of incubation of most infectious pathogens, it is clear every country relies to some extent on the health systems of other countries to prevent and protect their citizens from global health threats. Therefore, creating and maintaining a good health system in one country requires attention to interregional and international cooperation. Domestic and international spheres of public health policies are becoming more intertwined and inseparable.

Aims The prevalence of Type 2 diabetes mellitus (DM) has grown rapidly, but little is known about the drivers of inpatient spending in low- and middle-income countries. This study aims to compare the clinical presentation and expenditure on hospital admission for inpatients with a primary diagnosis of Type 2 DM in India, China, Thailand and Malaysia.

Methods We analysed data on adult, Type 2 DM patients admitted between 2005 and 2008 to five tertiary hospitals in the four countries, reporting expenditures relative to income per capita in 2007.

Results Hospital admission spending for diabetic inpatients with no complications ranged from 11 to 75% of per-capita income. Spending for patients with complications ranged from 6% to over 300% more than spending for patients without complications treated at the same hospital. Glycated haemoglobin was significantly higher for the uninsured patients, compared with insured patients, in India (8.6 vs. 8.1%), Hangzhou, China (9.0 vs. 8.1%), and Shandong, China (10.9 vs. 9.9%). When the hospital admission expenditures of the insured and uninsured patients were statistically different in India and China, the uninsured always spent less than the insured patients.

Conclusions With the rising prevalence of DM, households and health systems in these countries will face greater economic burdens. The returns to investment in preventing diabetic complications appear substantial. Countries with large out-of-pocket financing burdens such as India and China are associated with the widest gaps in resource use between insured and uninsured patients. This probably reflects both overuse by the insured and underuse by the uninsured.

Pharmaceutical policies are interlinked globally and at the same time deeply rooted in local culture. Prescribing Cultures examines how pharmaceuticals and their regulation play an important and often contentious role in the health systems of the Asia-Pacific.

The first section of this timely book analyzes pharmaceutical policy in China, Korea, Japan, Thailand, Taiwan, Australia, and India. The second section focuses on two cross-cutting themes: differences in "prescribing cultures" and physician dispensing; and the challenge of balancing access to drugs with incentives for innovation.

The book's contributors discuss important issues for U.S. policy. These include such hot-button topics as drug imports from Asia, regulation of global supply chains to assure drug safety and quality, new legislation to encourage development of drugs for neglected diseases, and the impact that decisions about pricing, regulation, and bilateral trade agreements have on access to medicines at home and abroad. In Prescribing Cultures, pharmaceutical policy reveals the economic trade-offs, political compromises, and historical trajectories that shape health systems.

Prescribing Cultures also illustrates how cultural legacies shape and are shaped by the forces of globalization, and thus will be of interest to students and scholars well beyond the confines of health policy.
