This study examines the impact of Health Maintenance Organization (HMO) coverage on the provision of preventive medicine. We investigate whether any association reflects selection effects on the part of patients and/or physicians or a causal impact of managed care itself. Causal effects may occur on the supply side or the demand side. Using a large national database of Medicare and non-Medicare...

This study investigates the effect of publicity on consumer demand. Although the marketing literature suggests that publicity can have an important influence on consumers’ choices, only a few studies have attempted to quantify how media coverage can affect consumer demand. The main obstacle to measuring the impact of publicity is that data on media coverage are difficult to interpret. To overco...

The relationship between distribution coverage and market share for an incumbent brand and for new entrants in the ready-to-drink iced tea market during its growth phase is explored using state space diagrams. This graphical visualization method was originally developed to disentangle lead–lag relationships between short nonstationary time series, a situation in which standard econometric metho...

This paper provides empirical evidence of Medicaid crowd out of demand for private long-term care insurance. Using data on the nearand young-elderly in the Health and Retirement Survey, our central estimate suggests that a $10,000 decrease in the level of assets an individual can keep while qualifying for Medicaid would increase private long-term care insurance coverage by 1.1 percentage points...

There has been considerable controversy about the most appropriate means of delivering insecticide-treated nets (ITNs) to prevent malaria. Household demand for ITNs is a key factor influencing the choice of delivery strategy, but evidence to date about price and income elasticities comes either from studies of hypothetical willingness to pay or small-scale policy experiments. This study estimat...

Dense satellite constellations recently emerged as a prominent solution to complementing terrestrial networks in attaining true global coverage. As such, analytic optimization techniques can be adopted rapidly maximize the benefits of such networks. This letter presents framework that relies on two primary tuning parameters optimize uplink performance; (i) constellation altitude and (ii) antenn...

Very High Throughput Satellites (VHTS) have a pivotal role in complementing terrestrial networks to increase traffic demand. VHTS systems currently assume uniform distribution of the service area, but real system, demands are not and dynamic. A possible solution is use flexible payloads, cost design increases considerably. On other hand, fixed payload that uses irregular beam coverage depending...

The US mobile phone service industry has dramatically consolidated over the last two decades. One justification for consolidation is that merged firms can provide consumers with larger coverage areas at lower costs. We estimate the willingness to pay for national coverage to evaluate this justification for past consolidation. As market level quantity data are not publicly available, we devise a...
