The Center for Health and Wellbeing is pleased to announce Kate Ho as its new Co-Director as of July 2018. She will serve alongside Janet Currie.

Professor Ho recently joined Princeton from Columbia University’s Economics Department where she was a faculty member from 2005-2013. Her research focuses on the industrial organization of the medical care market: she studies the interactions between firms (particularly health insurers and providers such as hospitals); their effects on the price and quality of care provided; and the impact of market design and regulations on these outcomes. For example, a recent project (co-authored with Robin Lee) develops and estimates a framework to assess the impact of insurer competition on negotiated hospital prices, premiums charged to consumers, and welfare. This paper was published in Econometrica in 2017. A related paper, also co-authored with Robin Lee and published in the American Economic Review, uses a model of hospital network formation to investigate the impact of regulating the breadth of insurers’ networks on hospital prices, premiums, and hence consumer surplus. A paper written with Fiona Scott Morton and Joe Hogan and published in the RAND Journal of Economics demonstrates that consumer inattention in the Medicare Part D market causes search frictions that prevent enrollees from switching away from relative high-priced plans. Reduced consumer inertia would both benefit consumers directly and remove a barrier to effective price competition between plans that would save both consumers and the government significant sums.

Professor Ho is a co-editor at the American Economic Journal: Economic Policy and has served on the editorial board of the American Economic Review, the American Economic Journal: Microeconomics and the Journal of Economic Literature. Her work has been recognized by the International Health Economics Association and the Journal of Applied Econometrics. Prior to her academic career she spent four years as private secretary (Chief of Staff) to the U.K. Minister of State for Health. 

Professor Ho sits in 285 Julis Romo Rabinowitz Building, and can be reached at

Teeto Ezeonu Morning Hike

About this photo Teeto said: 

This picture illustrates a typical hike back from the designated trapping site for the day. On this particular day, we were hiking back from Bear Cliffs, our farthest and most elevated site, which usually took 15-20 minutes. Each day, the six of us who were working with the Mouse Crew rotated such that five people went trapping every day. Each morning we took approximately 15 clean traps each (75 traps total) up to the two grids of the site where we were trapping and checked/replaced the 64 traps at each grid for mice. During peak season, we usually caught about 22 Peromyscus mice every day and a plethora of other by-catch including chipmunks, flying squirrels, voles, etc. The traps we used were Sherman live traps which allowed the mice to stay in an enclosed rectangular box with grain seeds once it tripped the trap. After collecting measurements and samples, the mice were released near their home sites each day. This picture captures a period of time on the mountain of heavy rain in the afternoon and at night. This, consequently, made it foggy during our morning hikes (and often reduced the number of mice caught that day). These mice will provide an abundance of data for research on parasite infection and specifically on interactions between nematodes and the Hantavirus, commonly observed in these mountain mice.

About this photo Maria said: 

I was in Madagascar doing thesis research when I took both of these photos. I spent the most of my time there surveying health centers and learning about the impact of cyclones on public health infrastructure and infectious disease incidence. Two days before I came back to the US, I went to Andasibe-Mantadia National Park and the Vakona Private Reserve to see some lemurs and other cool animals that can only be found in Madagascar. Since I'm concentrating in EEB, I was super excited about this trip and at the prospect of being able to see lemurs in their natural habitats. The picture of me with the lemur was taken at Vakona Private Reserve. The reserve has a small collection of islands that each hold different species of lemurs depending on whether they can coexist and their specific habitat needs. One of the islands that my guide and I canoed to had a small family of ring-tailed lemurs that were very friendly to humans. As we were rowing along the canal, the lemurs saw us and all six of them bounced alongside the boat until we docked. They bounce like kangaroos! I didn't realize the guide had put a piece of banana on my head so I was part surprised and part delighted when one of the really brave - and hungry - lemurs jumped on to the canoe and climbed up my shoulder. His friends climbed on to the boat too and I fed them them all little pieces of bananas. They were really soft and cuddly and although they don't like to be pet, they seemed to really enjoy climbing on me.
