Stability is often the goal for clearinghouses in matching markets, such as those matching residents to hospitals, students to schools, etc. Stable outcomes absent transfers need not be utilitarian effi cient, suggesting the potential value of transfers. We study the wedge between stability and effi ciency in large one-to-one matching markets. We show stable matchings are effi cient asymptotica...

Recent portable electronic devices have strict requirements regarding size, weight, and power. The power needed directly impacts the size of the required batteries, and larger batteries compromise the sizes and weights of portable devices. In order to design successful portable devices that maximize power and minimize size, devices should be operated in lowpower-consuming or self-powered mode. ...

The New York State Energy Research and Development Authority, NYSERDA, seeks to reduce the state’s energy consumption. Among its many activities, the authority supports incentives to purchase high-effi ciency motors. Ultra-high effi ciency, copper-rotor motors (CRMs) have been available for several years, but NYSERDA lacked industrial data on them. The authority therefore initiated an R&D progr...

Polymer solar cells (PSCs) have attracted considerable attention because of their advantages of low cost, light weight, and fl exibility in large area applications by ink-jet printing and rollto-roll solution processes. [ 1 ] The concept of bulk heterojunction (BHJ) has improved the power conversion effi ciencies (PCEs) of the PSCs signifi cantly by blending electron-donating conjugated polymer...

Wireless sensor networks (WSNs) consist of numerous low-power sensor nodes with limited computing ability and storage capacity. Maximizing energy savings is a crucial research area in WSN. Data aggregation is the most appropriate way to resolve energy issues involves various scheduling algorithms. This paper proposes a combined framework for data aggregation that resolves many data aggregation ...

One of the advantages of estimating a conduct parameter game, compared with the Lerner index, is that the knowledge of cost shifters is suffi cient to get the “implied marginal cost”estimates. Stochastic frontier literature suffers from the same problem that it requires a detailed data set in order to estimate cost effi ciencies of the firms. This paper develops a model to estimate firm specifi...

76 Vegetated buff ers are a well-studied and widely used agricultural management practice for reducing nonpointsource pollution. A wealth of literature provides experimental data on their mitigation effi cacy. Th is paper aggregated many of these results and performed a meta-analysis to quantify the relationships between pollutant removal effi cacy and buff er width, buff er slope, soil type, a...
