Valuing water quality in the United States using a national dataset on property values.

High-quality water resources provide a wide range of benefits, but the value of water quality is often not fully represented in environmental policy decisions, due in large part to an absence of water quality valuation estimates at large, policy relevant scales. Using data on property values with nationwide coverage across the contiguous United States, we estimate the benefits of lake water quality as measured through capitalization in housing markets. We find compelling evidence that homeowners place a premium on improved water quality. This premium is largest for lakefront property and decays with distance from the waterbody. In aggregate, we estimate that 10% improvement of water quality for the contiguous United States has a value of $6 to 9 billion to property owners. This study provides credible evidence for policymakers to incorporate lake water quality value estimates in environmental decision-making.

Spatial Heterogeneity in Hedonic Price Effects for Lake Water Quality.

This study uses Zillow's ZTRAX property transaction database to investigate variation in hedonic price effects of water clarity on single-family houses throughout the United States. We consider five spatial scales and estimate models using different sample selection criteria and model specifications. Our results indicate considerable spatial heterogeneity both within and across the four U.S. Census regions. However, we also find heterogeneity resulting from different types of investigator decisions, including sample selection and modelling choices. Thus, it is necessary to use practical knowledge to consider the limits of market areas and to investigate the robustness of estimation results to investigator choices. (JEL Q51).

The economic costs of jail-based methadone maintenance treatment.

BACKGROUND: The US has the highest incarceration rate in the world and spends $40-$80 billion to house inmates per year. It is well-known that a significant correlation is present between substance use and crime, especially over recent years as opioid use disorder (OUD) has grown exponentially. To mitigate OUD, methadone maintenance treatment (MMT) has demonstrated effectiveness in numerous randomized and quasi-experimental studies. A potentially fruitful environment for MMT is correctional facilities, particularly short-term facilities, such as city and county jails. However, little is known about the economic implications of MMT within correctional facilities. OBJECTIVE: The aim of the present study was to estimate the economic costs of jail-based MMT using data from a novel, established MMT program located within a large urban jail in New Mexico. METHODS: Data were collected using administrative records and by interviewing program administrators using a modified version of the Drug Abuse Treatment Cost Analysis Program (DATCAP). Both sensitivity analysis and cost-structure analysis were conducted to gauge the robustness of the findings. RESULTS: The average (per patient) weekly cost of MMT is $115 and the total treatment cost for an average treatment episode is $689. These costs are generally in-line with non-jail-based MMT programs of similar size. Weekly cost estimates range from $86 to $185 depending on the size of the treatment facility, with larger programs exhibiting lower per-patient costs. CONCLUSION: Results provide a valuable economic benchmark to policy makers, criminal justice officials, and program administrators considering establishing and/or expanding MMT in jail settings.
