Electronic fraud detection in the U.S. Medicaid Healthcare Program: lessons learned from other industries

It is estimated that between $600 and$850 billion annually is lost to fraud, waste, and abuse in the US healthcare system,with $125 to$175 billion of this due to fraudulent activity (Kelley 2009). Medicaid, a state-run, federally-matchedgovernment program which accounts for roughly one-quarter of all healthcare expenses in the US, has been particularlysusceptible targets for fraud in recent years. With escalating overall healthcare costs, payers, especially government-runprograms, must seek savings throughout the system to maintain reasonable quality of care standards. As such, the need foreffective fraud detection and prevention is critical. Electronic fraud detection systems are widely used in the insurance,telecommunications, and financial sectors. What lessons can be learned from these efforts and applied to improve frauddetection in the Medicaid health care program? In this paper, we conduct a systematic literature study to analyze theapplicability of existing electronic fraud detection techniques in similar industries to the US Medicaid program

Complete results for lag length selection

This paper presents the detailed results of employing the various lag-length-selection criteria outlined in "Lag Length Selection Criteria: Some Empirical Results for the St. Louis Equation.'' Tables 1 through 6 are for a maximum lag of 8; tables 7 through 12, a maximum lag of 12; and tables 13 through 18, a maximum lag of 16. Table 19 contains the likelihood ratio test results of all the alternative lag specifications considered.

What do Almon's endpoint constraints constrain?

In this paper we show that Almon's (1965) endpoint constraints do not constrain the endpoints, as commonly thought. In particular, the endpoints are not constrained to equal zero. Consequently, these constraints have neither a basis in economic theory nor the econometric justification frequently ascribed to them.

Discount rate changes and the foreign exchange market

Changes in the discount rate can have an associated announcement effect on the foreign exchange value of the dollar only if these changes are not anticipated by the market. This paper provides evidence to support this contention. Specifically, discount rate changes made for reasons other than technical adjustments have not been anticipated fully and consequently, their announcement has had a significant impact on the dollar's exchange rate. Furthermore, results are obtained that support the hypothesis that unanticipated discount rate changes alter the expectation of the rate of future inflation.
