OBJECTIVE To identify the effect of insurance coverage on prescription utilization by Medicare beneficiaries. DATA SOURCES/STUDY SETTING Secondary data from the 1999 Medicare Current Beneficiary Survey (MCBS) Cost and Use files, a nationally representative survey of Medicare enrollees. STUDY DESIGN The paper uses a cross-sectional design with (1) a standard regression framework to estimate ...

This paper uses a general method of moment regression technique to estimate an energy demand function with a dataset covering 71 countries between 1965 and 2010. The estimated results show that countries undergoing rapid economic growth may show relatively higher income and price elasticities in the long run. The higher income elasticities and lower price elasticity in the short run of rapid gr...

According to the standard analysis of commodity prices, stockpiling is a necessary signature of speculation. This paper develops an approach suggesting that speculation may temporarily push crude oil prices above the level justified by physical-market fundamentals, without necessarily resulting in a significant increase in oil inventories. Looking beyond debate on the value of oil-demand price-...

demand for farm output is theoretically consistent with consumer demand and marketing performance. many studies have focused on demand interrelationships at the retail level, but not on the demand for farm output. in this study, derived demand elasticities of sheep, beef and chicken were estimated in a complete system of demand functions by seemingly unrelated regression estimator (sure) for th...

Nowadays, demand response programs (DRPs) play an important role in price reduction and reliability improvement. In this paper, an optimal integrated model for the emergency demand response program (EDRP) and dynamic economic emission dispatch (DEED) problem has been developed. Customer’s behavior is modeled based on the price elasticity matrix (PEM) by which the level of DRP is determined for ...

We test the effect of report cards on consumer choice in the HMO market. Federal employees were provided with report cards on a limited basis in 1995 and then on a widespread basis in 1996. Exploiting this natural experiment, we find that subjective measures of quality and coverage influence plan choices, after controlling for plan premiums, expected out of pocket expenses and service coverages...
