Our objective is to analyze this problem both theoretically and empirically. From a theoretical perspective, we are interested in modeling the method the consumers choose providers with or without access to pricing data as well as quality data. Such model can identify various trade-offs involved in this process such as the importance of pricing data for various types of consumers and the use of prices as signal for quality. |

| 08/26/2015 | Amanda E. Kowalski | Yale University, National Bureau of Economic Research | CT | 2005-2014 | The objective of this study is to measure the amount that young, healthy individuals subsidize the healthcare of older, sicker individuals. This information would help inform a decision regarding the amount of cross-subsidization that is socially optimal in insurance markets. These answers, in turn, have implications for other portions of the ACA, including individual mandate. |

| 05/14/2015 | Haizhen Lin | Indiana University | IN | 2009-2014 | Health insurance carriers face a “two-sided marketâ€: A larger provider network leads to more consumer enrollment, which in turn encourages more providers to join the plan’s network. Therefore consumer behavior and provider behavior jointly create a positive network effect. Network effect is crucial in determining market structure in health insurance markets. Despite its importance, the two-sidedness of insurance market has been largely ignored in the literature. This project aims to fill the gap in the literature and will shed lights on insurer competition and provide policy implications for insurer mergers. |
| 05/14/2015 | Stacey Eccleston | Health Care Incentives Improvement Institute | MA | 2009-2014 | The purpose of the project is two-fold: To evaluate the extent of variation in costs and quality of care for similar conditions or episodes, to attribute the variation to differences in prices versus utilization and to include that information in national benchmarks. The second is to provide transparency on costs and quality of care by publishing metrics for the state and specific to providers. The information will be made available and published free of charge. |
| 05/14/2015 | Steve Cicala and Ethan Lieber | Harvard University and University of Chicago | IL | 2005-2014 | Many states and the federal government have established medical loss ratios that could influence how health insurers behave. Very little is known about insurer's responses to mandated medical loss ratios. We will use regression analysis to compare the probability of claim denial for patients as well as the supply of care provided before and after the medical loss ratio goes into insurance from a self-insured company (not subject to the medical loss ratio regulation) as control groups. |
| 04/22/2015 | Craig Garthwaite | Northwestern University | IL | 2005-2014 | We are interested in studying how the NH HealthCost transparency initiative affected consumer choice and provider pricing. The HealthCost initiative is the most comprehensive healthcare transparency initiative in the country, and therefore interesting in its own right. Furthermore, understanding the consequences of the initiative is important because of the broader movement towards consumer directed health care plans (CDHP). |
| 04/22/2015 | Craig Garthwaite | Northwestern University | IL | 2005-2014 | This project will look at the relationship between macroeconomic fluctuations and the health of the pool of privately insured patients. |
| 04/22/2015 | Craig Garthwaite | Northwestern University | IL | 2005-2014 | This project will investigate the determinants of medical treatment decisions. A central questions in healthcare economics and most important questions underlying health policy decisions is whether providers make "the right" treatment decisions. Determining when physicians make "the right" treatment decisions, as well what forces (such as immediate financial incentives, monitoring by patients/insurers or long run reputational concerns) affect the extent of deviations is of great policy import. |
| 04/22/2015 | Ateev Mehrotra, MD | Harvard Medical School | MA | 2006-2014 | To understand the impact of Health Cost and price transparency initiatives more boradly, we propose a comprehensive evaluation assessing its impact on utilzation and price shopping behavior. |
| 04/22/2015 | Jianjing Lin | Department of Economics, University of Arizona | AZ | 2005-2014 | The purpose of this project is to study the effect of price transparency on health care expenditure. The way to shop medical goods and services is different in the sense that price actually paid is remarkably opaque. The goal of this project is to fill gaps in this evidence base and provide sound empirical support for future policy. |
| 04/22/2015 | Kate Ho | Columbia University | NY | 2005-2014 | As healthcare economists, our goal is to find ways to improve healthcare efficiency and patient welfare. To that end, we are interested in physician practice style and under what circumstances physician practice style is inefficient or conributes to wasteful healthcare spending. |
| 04/22/2015 | Keith Marzilli Ericson | Boston University School of Management | MA | 2005-2014 | We will use health insurance claims data from Massachusetts, New Hampshire, and Kansas to examine characteristics of physician provider networks and health insurance policies, as well as possible relationships with patient and economic outcomes. To conduct the analyses, we will use regression techniques, network analysis, and simulation. The study will be used to better understand provider and enrollee behaviors. |
| 04/22/2015 | Robert Town | The Wharton School, University of Pennsylvania | PA | 2005-2014 | Our motivation is the observation by some studies that higher provider price transparency does not necessarily lead to lower prices in the health care market.

| 04/22/2015 | Sarah Miller | University of Michigan | MI | 2005-2014 | The goal of this project is to understand how patent protection of prescription drugs affects the utilization of these drugs, the costs faced by consumers and insurers, and the health of patients. |
| 07/18/2011 | Craig Garthwaite | Northwestern University | IL | 2005-2010 | This project will look at the relationship between macroeconomic fluctuations and the health of the pool of privately insured patients. The project will study the causes of health insurance rate increases. Also, it will study the reclassification of risk by applying market information to theory. |

| 10/04/2010 | Constance Salemi | U.S. Federal Trade Commission | DC | 2005-2009 | Data will be used to examine hypotheses regarding the pricing of physician services across New Hampshire, especially in areas where pricing power may be growing. The analysis is intended to support a recommendation to the FTC Bureaus and possibly to the FTC itself to close or continue an investigation of the physician services markets in central New Hampshire. |
| 09/17/2010 | Jo Porter | University of New Hampshire, NH Institute for Health Policy and Practice (NHIHPP) | NH | 2005-2009 | NHIHPP has several projects, including the NH Citizens Health Initiative, that seek to understand the cost and quality drivers within New Hampshire's healthcare system. To do this, the Initiative will produce a series of standard and ad hoc summary reports. Our hypothesis is that there are a multitude of diagnoses and medical conditions that are driving the majority of costs within the system. We expect to run a series of summary reports as the first step in order to provide an overall picture of the state, and then run a series of drill-down reports. We are interested in price variation across payers, providers, insurance product line, medical conditions, and regional differences. We also expect to apply an episode treatment grouper methodology to the data set. |
| 03/29/2010 | Judy Rees | New Hampshire State Cancer Registry | NH | 2005-2008 | Create a matched, linked database from state cancer registry, claims, and hospital discharge data. Linked data will be used to evaluate potential enhancements that can be made to New Hampshire State Cancer Registry data via linkages with other data. Additionally, with better quality registry data, it may be possible to perform evaluations of the data that will ultimately benefit the population. The project is a first step towards that goal and, as such, is unlikely to show an immediate direct benefit. However, the database that will be created by this linkage will then be available to (and owned by) NH DHHS for a variety of future research and public health uses. Project involves CDC, Westat, NH DHHS, Onpoint, Dartmouth. |
