We estimate the post-release economic effects of participation in prison-based General Educational Development (GED) programs using a panel of earnings records and a rich set of individual information from administrative data in the state of Florida. Fixed effects estimates of the impact of participating in the GED education program show post-release quarterly earnings gains of about 15 percent...
Students in a calculus-based mechanics course at MIT were given the conceptual Force Concept Inventory (FCI) test both at the start and the end of the course. Gains in student scores are correlated with individual use of the different components in the course: small-group tutorial sessions, written problem sets, an interactive web-based problem set, collaborative work and number of sessions vie...
Shall We Kill or Enslave Caesar? Analyzing the Caesar Model When a society overthrows a ruler – call the ruler Caesar – what determines whether Caesar is killed or enslaved? This paper presents a model of killing versus enslaving Caesar, based on a new theory which unifies justice, status, and power. The model pertains to societies which value ordinal goods like bravery, yielding predictions fo...
J Comput Assist Learn. 2018;1–14. Abstract Educational robotics programs offer an engaging opportunity to potentially teach core computer science concepts and practices in K–12 classrooms. Here, we test the effects of units with different programming content within a virtual robotics context on both learning gains and motivational changes in middle school (6th–8th grade) robotics classrooms. Si...
Throughout much of its existence, Nevada’s gambling industry has been dominated by table games. Historically, slot machines were of secondary importance because they did not generate much revenue and were costly to maintain and operate. Starting in the late 1970s, a series of technological milestones improved the form and function of slot machines, and fueled replacement cycles on casino floors...
We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and Rodriguez-Clare (2012) to encompass revenue-generating import tariffs. Our formula permits easy quantification...
This study provides new insight into the market’s allocation of dividend-related and capital gains-based returns on common stock around earnings announcement surprises. To the extent that investors’ cash flow forecasts are revised as earnings surprises occur, Americus Trust prime and score returns reflect changes in respective future dividends and capital gains. About 70% of the value gain from...
List decoding of turbo codes is analyzed under the assumption of a maximum-likelihood (ML) list decoder. It is shown that large asymptotic gains can be achieved on both the additive white Gaussian noise (AWGN) and fully interleaved flat Rayleigh-fading channels. It is also shown that the relative asymptotic gains for turbo codes are larger than those for convolutional codes. Finally, a practica...
The paper considers a distributed robust estimation problem over a network with Markovian randomly varying topology. The objective is to deal with network variations locally, by switching observer gains at affected nodes only. We propose sufficient conditions which guarantee a suboptimal H∞ level of relative disagreement of estimates in such observer networks. When the status of the network is ...
