We introduce a new interactive system: a game that is fun and can be used to create valuable output. When people play the game they help determine the contents of images by providing meaningful labels for them. If the game is played as much as popular online games, we estimate that most images

of the performance-critical code was generated automatically by a special-purpose compiler, called genfft, that outputs C code. Written in Objective Caml, genfft can produce DFT programs for any input length, and it can specialize the DFT program for the common case where the input data are real instead of complex

Recently, many formal methods, such as the SCR (Software Cost Reduction) requirements method, have been proposed for improving the quality of software specifications. Although improved specifications are valuable, the ultimate objective of software development is to produce software

given level of output. The economic magnitude of the effects is large. The results hold both in models with country and firm fixed effects. The results survive several robustness checks, including different measures of output and efficiency, and instrumenting for corruption. Other elements associated

in the current delivery of the affordable housing elements negotiated in S106 agreements. During a time when planning permissions for affordable homes provided through S106 are increasing rapidly, this research provides valuable insights for the future development of S106 monitoring and implementation

A new I-f oscillator provides both sine and square outputs as well as adjustable-phase sine and square outputs over a range from 60 kc/s down to 0.005 c/s. TEST SIGNALS at frequencies below the audio range are valuable in many applications, including the check-out of medical and geophysical

advisor, Dr. John Papapolymerou. His guidance and support were valuable assets as well as his ability to tolerate my unique brand of humor. Thanks to the staff of the MIRC cleanroom, especially Vinny. I would also like to thank all the staff of TSRB who helped to make life easier to get work done. I would

for these aforementioned regularities. Moreover, the joint interaction of countercyclical interest rates and search-matching frictions can go a long way in accounting for higher consumption variability relative to output and countercyclical current account observed in emerging markets. Extending this baseline model

of the duration of terms, which varies markedly across countries. We exploit a natural experiment in the Argentine House of Representatives to overcome this identi…cation problem. Results for various objective measures of legislative output show that longer terms enhance legislative performance. We discuss
