The RAND Journal of Economics, 2009 Unsolicited advertising messages vie for scarce attention. “Junk” mail, “spam” e‐mail, and telemarketing calls need both parties to exert effort to generate transactions. Message receivers supply attention according to average message benefit, while the marginal sender determines congestion. Costlier transmission may improve average message benefit so

Abstract 1. 1. The performance of lung in pulmonary congestion has been considered in terms of anatomic and physiologic abnormalities. 2. 2. The characteristic breathing pattern of pulmonary congestion is one of tachypnea and hyperventilation. This is interpreted as a device to minimize the work and energy cost of breathing. 3. 3.

The incidence of congestion and congestion tolls
Journal of Urban Economics, 1980Abstract In contrast with the enormous literature on efficiency aspects of congestion tolls, very little has appeared on their equity implications. Simulation is applied to a standard urban model to learn about the distributional aspects of an optimal toll, or the absence of one.

Highway congestion and congestion tolls
Journal of Urban Economics, 1977Highway congestion is ubiquitous. We model the speed-flow relationship, identifying private and social costs, and the implied congestion toll for a number of proposed formulations. Using data for a limited access highway, we estimate these speed-flow relationships and find that flow as a quadratic function of speed fits best. The unit of observation is

SIAM Journal on Applied Mathematics, 2004
Summary: We analyze a class of second-order traffic models and show that these models support stable oscillatory traveling waves typical of the waves observed on a congested roadway. The basic model has trivial or constant solutions where cars are uniformly spaced and travel at a constant equilibrium velocity that is determined by the car spacing.

Individuals have an increased incentive to invest when they know that they can sell their investments whenever they need funds. However, this increase in investments can also lead to a reduction in aggregate returns, as it exacerbates the negative externalities that individuals impose on each other whenever they invest.

Passive hepatic congestion may result from a variety of distinct cardiovascular conditions. Injury to the liver caused by congestion is often asymptomatic and may not be recognized clinically. Diagnosis of congestive hepatopathy is important as it has the potential to cause complications including hepatic fibrosis and development of benign and ...
