There is a consensus that statistical agencies should report medical data by disease rather than by service. This study computes price indexes that are necessary to deflate nominal disease expenditures and to decompose their growth into price, treated prevalence and output per patient growth. Unlike previous studies, it uses methods that can be implemented by the Bureau of Labor Statistics (BLS). For the calendar years 2005-2010, I find that these feasible disease based indexes are approximately 1% lower on an annual basis than indexes computed by current methods at BLS. This gives evidence that traditional medical price indexes have not accounted for the more efficient use of medical inputs in treating most diseases. © 2013 Published by Elsevier B.V.

The utilization of health care services has undergone several important shifts in recent years that have implications for the cost of medical care. We empirically document the presence of these shifts for a broad list of medical conditions and assess the implications for price indexes. Following the earlier literature, we compare the growth of two price measures: one that tracks expenditures for the services actually provided to treat conditions and another that holds the mix of those services fixed over time. Using retrospective claims data for a sample of commercially insured patients, we find that, on average, expenditures to treat diseases rose 11% from 2003Q1 to 2005Q4 and would have risen even faster, 18%, had the mix of services remained fixed at the 2003Q1 levels. This suggests that fixed-basket price indexes, as are used in the official statistics, could overstate true price growth significantly. © 2011.

Background: Relatively little is known about seasonal patterns in occupational injury risk. Injury risk may vary seasonally due to weather-related factors or changing work exposure. Employer confusion about recordkeeping rules and injury occurrence near year end may also lead to an undercount of year-end injuries. Methods: Case records from the Bureau of Labor Statistics' Survey of Occupational Injuries and Illnesses and Census of Fatal Occupational Injuries were used to determine seasonality for a variety of injury types. Results: Reported injury rates were higher in summer and lower at year end. Difficult-to-identify injuries showed greater year-end incidence declines. Conclusions: End-of-year injury declines may have reflected reporting errors for some injury types. The summertime increase in injury risk was broad-based and presumably reflected real seasonal factors. Am. J. Ind. Med. 58:519-527, 2015. © 2015 Wiley Periodicals, Inc.

Most indexes in the Consumer Price Index (CPI) use a form of the "matched-model" approach. It is frequently assumed that this approach accurately reflects inflation for items that have no major trend in quality. In this paper we investigate that hypothesis using CPI data for retail food items. We find that CPI analysts may be correct on average when they decide that new and replacement items are similar in quality. We also find, however, that when sample items are replaced by items of significantly different quality the CPI imputation procedures may underestimate price change and overstate quality change. © 2011 AEA.
