Unbiased Analysis of Today's Healthcare Issues
One trend in recent years is how many hospitals are being purchased by large regional or national hospital chains. An April 2019 slide deck from the NIHCM Foundation shows this trend graphically. A paper by Hsieh and Rossi-Hansberg (2019) provide some aggregate data as well as a case study from the Boston area. Four decades…
Many researchers complain that physicians often use treatments with little evidence to base these decisions. From off-label prescribing, to unstudied surgical procedures, physicians are often painted as cavalier practitioners who don’t read studies. For instance, Austin Frakt at Incidental Economist writes: The British Medical Journal sifted through the evidence for thousands of medical treatments to assess…

Granger causality basically identifies a variable as causal if: (i) it occurs the outcome of interest and (ii) including past…
Let’s say we are interested in determining whether a particular treatment improves quality of life. Common measures of quality of life include EQ-5D, SF-12, and SF-36, among others. However, a systematic review of 237 randomized controlled trials found that only 43% collected SF-12 or SF-36 measures. If you are measuring a treatment’s effect on quality…
How have discrete choice experiments changed over time? This is the question Soekhai et al. (2018) try to answer. They conduct a systematic literature review covering 27 years of data. Below I summarize some of their findings graphically. First, you see a trend of an increasing number of DCEs. We also see that whereas DCEs…

Luxury goods are defined as goods that increase as a share of a person’s (or country’s) budget as income increases; necessity goods are defined as goods that decrease as a share of a person’s (or country’s) budget as income increases. There is actually mixed evidence on the topic…
