Determining the Number of Factors in Approximate Factor Models

by Jushan Bai, Serena Ng , 2000
"... In this paper we develop some statistical theory for factor models of large dimensions. The focus is the determination of the number of factors, which is an unresolved issue in the rapidly growing literature on multifactor models. We propose a panel Cp criterion and show that the number of factors c ..."

Dynamic capabilities and strategic management

by David J. Teece, Gary Pisano, Amy Shuen - Strategic Management Journal , 1997
"... The dynamic capabilities framework analyzes the sources and methods of wealth creation and capture by private enterprise firms operating in environments of rapid technological change. The competitive advantage of firms is seen as resting on distinctive processes (ways of coordinating and combining), ..."

Technical Change, Inequality, and The Labor Market

by Daron Acemoglu - Journal of Economic Literature , 2002
"... This essay discusses the effect of technical change on wage inequality. I argue that the behavior of wages and returns to schooling indicates that technical change has been skill-biased during the past sixty years. Furthermore, the recent increase in inequality is most likely due to an acceleration ..."

The Patent Paradox Revisited: An Empirical Study of Patenting in the US Semiconductor Industry, 1979-1995

by Bronwyn H. Hall, Rosemarie Ham Ziedonis , 2000
"... This paper examines the patenting behavior of firms in an industry characterized by rapid technological change and cumulative innovation. Recent survey evidence suggests that semiconductor firms do not rely heavily on patents to appropriate the returns to R&D, despite the strengthening of US pat ..."

Managerial decisions and long-term stock price performance

by Mark L. Mitchell, Erik Stafford - Journal of Business , 2000
"... A rapidly growing literature claims to reject the efficient market hypothesis by producing large estimates of long-term abnormal returns following major corporate events. The preferred methodology in this literature is to calculate average multi-year buy-and-hold abnormal returns and conduct inferen ..."

Microstrip filters for RF/microwave applications,

by . J S Hong , M J Lancaster , 2001
"... cated bandpass filter is at 2.47 GHz and the fractional bandwidth is 5%. The measured insertion loss and return loss of the filter is Ϫ3.68 and Ϫ14.92 dB, respectively. The measured center frequency, insertion loss and return loss of the fabricated filter are in agreement with simulated results. ..."

Coalition Structure Generation with Worst Case Guarantees

by Tuomas Sandholm, Kate Larson , Martin Andersson , Onn Shehory , Fernando Tohmé , 1999
"... Coalition formation is a key topic in multiagent systems. One may prefer a coalition structure that maximizes the sum of the values of the coalitions, but often the number of coalition structures is too large to allow exhaustive search for the optimal one. Furthermore, finding the optimal coalition ..."

remains, our anytime algorithm searches further, and establishes a progressively lower tight bound. Surprisingly, just searching one more node drops the bound in half. As desired, our algorithm lowers the bound rapidly early on, and exhibits diminishing returns to computation. It also significantly

Roughing It Up: Including Jump Components in the Measurement, Modeling and Forecasting of Return Volatility

by Torben G. Andersen , Tim Bollerslev , Francis X. Diebold - REVIEW OF ECONOMICS AND STATISTICS, FORTHCOMING , 2006
"... A rapidly growing literature has documented important improvements in financial return volatility measurement and forecasting via use of realized variation measures constructed from high-frequency returns coupled with simple modeling procedures. Building on recent theoretical results in Barndorff-Ni ..."

Sampling-based algorithms for optimal motion planning

by Sertac Karaman, Emilio Frazzoli - International Journal of Robotics Research (IJRR
"... During the last decade, sampling-based path planning algorithms, such as Probabilistic RoadMaps (PRM) and Rapidly-exploring Random Trees (RRT), have been shown to work well in practice and possess theoretical guarantees such as probabilistic completeness. However, little effort has been devoted to t ..."

Can Relationship Banking Survive Competition

by Arnoud W. A. Boot, Anjan V. Thakor - Journal of Finance , 1999
"... How will banks evolve as competition increases from other banks and from the capital market? Will banks become more like capital market underwriters and offer passive transaction loans or return to their roots as relationship lending experts? These are the questions we address. Our key result is tha ..."
