While Medicaid program as one of the biggest cost driver in health care expenditure items has been criticized for the enormous waste of spending, weak incentives from healthcare providers, patients, and administrators are often blamed for not preventing the fraudulent cases of public money. Given there is a lack of empirical studies, this paper tries to construct and empirically test an exploratory model of state control over Medicaid fraud and abuse. Data of the money recovered(lagged dependent variable) is collected from 40 State Medicaid Fraud Control Unit’s reports and various sources. Independent variables from 1998 to 2001 are grouped into two categories especially at state level: institutional (or administrative) factors and legislative factors. Relative to administrative factors, legislative statutory control over governmental enforcement efforts is proven to be very effective as a mechanism to hold public employees accountable in recovering money.
