In this paper, a novel multi-objective bus stop location model is proposed, which considers not only the coverage of demand and minimization of access time but also the necessities of suitable stops for transit network design phase. Three objective functions are considered including minimizing (I) sum of the total access distance (time), (II) the weighted combination of stops, and (III) the num...

On August 23rd, 2004 the Department of Labor revised Fair Labor Standards Act (FLSA) overtime coverage rules. Under the FLSA, those who are covered receive time-and-a-half pay for all hours worked above forty hours while those who are exempt do not receive mandatory overtime pay. By altering the so-called “white-collar exemptions” to the FLSA, the Department of Labor ensured that some workers w...

In this study, using a comprehensive dataset on business media coverage and textual analysis of the discussions in firms’ quarterly earnings conference calls, we show that when management fails to satisfy demand for information, ceteris paribus, their firms receive less coverage. Poor information environment hurts information-creation capacity media, while such an does not similar association w...

In this paper, we propose models and solution approaches for determining the facility locations of medical supplies in response to large-scale emergencies. We address the demand uncertainty and medical supply insufficiency by providing each demand point with services from a multiple quantity of facilities that are located at different quality levels (distances). The problem is formulated as a m...

Despite significant global efforts to improve vaccination coverage against major childhood diseases, vaccination rates are below 90%. To eradicate diseases such as measles, however, vaccination rates close to 95% are needed. We use a randomized experiment to investigate the effect of a demand incentive, a conditional cash transfer program, in improving vaccination coverage in rural Nicaragua. D...

Over the period 1997 to 2000, the Australian government introduced two waves of price subsidies, then liberalised regulation to encourage private health insurance. Most of the increase in coverage occurred after the liberalization. Thus, it appears that this policy change rather than the earlier subsidies, explains most of the increase. We explore the relative impact of the different policy cha...
