    Extensive And Intensive Investment Over The Business Cycle

    Investment of U.S. firms responds asymmetrically to Tobin's Q: Investment of established firms - 'Intensive' investment - reacts negatively to Q whereas investment of new firms -'Extensive' investment - responds positively and elastically to Q. This asymmetry, the authors argue, reflects a difference between established and new firms in the...

    What Is Happening To The Impact Of Financial Deepening On Economic Growth?

    Although the finance-growth relationship is now firmly entrenched in the empirical literature, the authors show that it is not as strong in more recent data as it was in the original studies with data for the period from 1960 to 1989. They consider several explanations. First, they find that the...

    Inflation, Finance, And Growth: A Trilateral Analysis

    A large body of evidence links financial development to economic growth, yet the channels through which inflation affects this relationship and its stability have been less thoroughly explored. The authors take an econometric and graphical approach to examining these channels, and find that higher levels of financial development, combined with...

    Evaluating Transport Protocols for Real-Time Event Stream Processing Middleware and Applications

    Real-Time Event Stream Processing (RT-ESP) applications must synchronize continuous data streams despite fluctuations in resource availability. Satisfying these needs of RT-ESP applications requires predictable QoS from the underlying publish/subscribe (pub/sub) middleware. If a transport protocol is not capable of meeting the QoS requirements within a dynamic environment, the middleware must...

    Maintaining QoS for Publish/Subscribe Middleware Via Autonomic Adaptation

    Quality of Service (QoS)-enabled Publish/Subscribe (Pub/Sub) middleware provides powerful support for data dissemination. It is hard, however, to maintain specified QoS properties such as reliability and latency in dynamic environments such as disaster relief operations or power grids. For example, managing QoS manually is not feasible in dynamic systems due...

    A Model-Driven QoS Provisioning Engine for Cyber Physical Systems

    Developing cyber physical systems is hard since it requires a coordinated, physics-aware allocation of CPU and network resources to satisfy their end-to-end Quality-of-Service (QoS) requirements. This paper provides two contributions to address these challenges. The authors present model-driven middleware called NetQoPE that shields application developers from the complexities of programming...

    Rigidity, Dispersion And Discreteness In Chain Prices

    This paper studies price setting within a chain of grocery stores, using a scanner database that contains observations of retail prices for 435 products within 75 stores over 121 weeks. The authors find price dispersion within the chain. Although price dispersion is pervasive 75% of the prices are equal to...

    What We Can Learn From 4th Down Decisions

    Owen professor Ranga Ramanujam and other researchers studied 22,603 fourth-down decisions over five NFL seasons to understand when teams were more likely to attempt a seemingly risky fourth-down conversion. The goal is to apply this research to organizations. These findings are reported in a forthcoming study in Organization Science.

    Model-Driven Auto-Scaling of Green Cloud Computing Infrastructure

    Cloud computing can reduce power consumption by using virtualized computational resources to provision an application's computational resources on-demand. Auto-scaling is an important cloud computing technique that dynamically allocates computational resources to applications to match their current loads precisely, thereby removing resources that would otherwise remain idle and waste power. This...

    Sum-Product Based Optimization for Scalable Video Streams in Peer-to-Peer Mesh Network

    Receiver heterogeneity of a P2P network can be effectively addressed by scalable video streams. Due to the discontinuous nature of scalable video, traditional convex-optimization approach is not applicable. The authors propose a message-passing based approach for optimization using the sum-product update algorithm. Advantage of this simple but elegant approach over...

    Passivity-Based Design Of Wireless Networked Control Systems Subject to Time-Varying Delays

    Real-life cyber-physical systems, such as automotive vehicles, building automation systems, and groups of unmanned vehicles are monitored and controlled by networked control systems. The overall system dynamics emerges from the interaction among physical dynamics, computational dynamics, and communication networks. Network uncertainties such as time-varying delay and packet loss cause significant...
