Risk Selection and Risk Adjustment
Synopsis: Risk selection, which occurs when an individual’s demand for a product is correlated with her risk, creates inefficiencies and inequalities in markets for those products and services. Studies have shown that risk selection often occurs in health care markets, especially in markets for health insurance. Risk adjustment is a method that has been developed to correct those inefficiencies...
متن کاملGeneralized Adjustment Under Confounding and Selection Biases
Selection and confounding biases are the two most common impediments to the applicability of causal inference methods in large-scale settings. We generalize the notion of backdoor adjustment to account for both biases and leverage external data that may be available without selection bias (e.g., data from census). We introduce the notion of adjustment pair and present complete graphical conditi...
متن کاملRisk adjustment and risk selection in Europe: 6 years later.
In this paper we analyse the developments concerning risk adjustment and risk selection in Belgium, Germany, Israel, the Netherlands and Switzerland in the period 2000-2006. Since 2000 two major trends can be observed. On the one hand the risk adjustment systems have been improved, for example, by adding relevant health-based risk adjusters. On the other hand in all five countries there is evid...
متن کاملCausal Effect Identification by Adjustment under Confounding and Selection Biases
Controlling for selection and confounding biases are two of the most challenging problems in the empirical sciences as well as in artificial intelligence tasks. Covariate adjustment (or, Backdoor Adjustment) is the most pervasive technique used for controlling confounding bias, but the same is oblivious to issues of sampling selection. In this paper, we introduce a generalized version of covari...
متن کاملGeneralized modeling approaches to risk adjustment of skewed outcomes data.
There are two broad classes of models used to address the econometric problems caused by skewness in data commonly encountered in health care applications: (1) transformation to deal with skewness (e.g., ordinary least square (OLS) on ln(y)); and (2) alternative weighting approaches based on exponential conditional models (ECM) and generalized linear model (GLM) approaches. In this paper, we en...
