How do for-profit and not-for-profit hospitals differ? We consider one dimension: the shifting of a patient's diagnostic related group (DRG) to one that yields a greater reimbursement from the Medicare system, also known as upcoding. It has played a major role in recent federal lawsuits against...

There is considerable controversy about the causes of regional variations in health care expenditures. We use vignettes from patient and physician surveys linked to Medicare expenditures at the Hospital Referral Region to test whether patient demand-side factors or physician supply-side factors...

Why have health care costs moderated in the last decade? Some have suggested the Great Recession alone was the cause, but health expenditure growth in the depths of the recession was nearly identical to growth prior to the recession. Nor can the Affordable Care Act (ACA) can take credit, since...

Many Americans report chronic and disabling pain, even in the absence of identifiable clinical disorders. We first examine the prevalence of pain in the older U.S. population using the Health and Retirement Study (HRS). Among 50-59 year females, for example, pain rates ranged from 26 percent for...

Many critics believed that the Tax Reform Act of 1986 (TRA86) would discourage saving. Yet personal saving rates have rebounded since 1987. This rebound might have been caused by a general decline in marginal tax rates on household saving. And we estimate, at least for the 1980s, a positive...

Technological advances in health care have been shown to yield large average health benefits for the U.S. elderly population. However, less is known about the marginal or incremental benefits of health care spending. We use geographical variations in health care spending to measure the marginal...

Frequent shifts in tax policy can increase uncertainty about future net-of-tax wages and interest income. This paper measures the impact of uncertain tax policy on savings, labor supply, and welfare in the United States. A vector autoregression model with six variables was estimated which found...

In the past two decades the widely reported personal saving rate in the United States has dropped from double digits to below zero. First, we attempt to account for the decline in the National Income and Product Accounts (NIPA) saving rate. The macroeconomic literature suggests that about half...

In his classic 1957 study of hybrid corn, Griliches emphasized the importance of economic incentives and profitability in the adoption of new technology, and this focus has been continued in the economics literature. But there is a distinct literature with roots in sociology emphasizing the...

Many observers believe current aging baby boomers are woefully unprepared for retirement. Others raise the prospect that Americans are saving too much for retirement. This paper attempts to reconcile these contrasting views using a simple life cycle model and a more sophisticated retirement...
