This paper examines the choice of pension scheme and job mobility in Britain. Workers in Britain can choose to belong wholly to the social security (public pension) programme, or to a company-provided plan (occupational pension), or to purchase their own individual pension. We use household panel data for the 1990s to show that individuals that subsequently move job select pension arrangements ...

The effect of interest rates, capital goods prices, and taxes on the capital stock is an issue of central importance in economics, with implications for monetary policy, business cycle models, tax policy, economic development, growth, and other areas. For more than 30 years it has been difficult to obtain precise estimates of these effects, and there is little consensus in the profession on the...

Abstract: In the actual study, two digital detectors were investigated : an amorphous silicon flat panel and a TDI multilinear detector. The contrast and IQI sensitivity was selected to compare flat panel and film radiography. The influence of X-ray conditions was assessed in the case of flat panel. Spatial resolution of both digital detectors was assessed by adapting the geometrical magnificat...

The US industrial sector displays heterogeneity among firms on the basis of their size: smaller firms exhibit a higher profit rate, lower survival probability and difficulty in accessing the capital market. A simple theoretical model that generates these features based on private information regarding managerial actions at firm-level production is developed and tested. Using a large panel of pu...

The size limitations of mobile devices can make information display especially difficult. Micro-displays must take into account the viability of different sizes and configurations for informing users, the flexibility they provide for different types of messages, and under which conditions these results are achieved. An experiment was performed to measure user learning and comprehension of five ...

We examine the relationship between position in a network of relationships and organizational performance. Drawing on ten years of observations (1988-1997) for nearly 400 firms in the human biotechnology industry, we utilize three types of panel regressions to unravel the complex linkages between network structure, patenting, and various firm-level outcome measures. Our results highlight the cr...

Large vibrating plates are used as thunder sheets in orchestras. We have extended the use of flat plates by cementing a flat panel electroacoustic transducer on a large brass sheet. Because of the thickness of the panel, the output is subject to nonlinear distortion. When combined with a real-time input and signal processing algorithm, the active brass plate can become an effective musical inst...

Tomographic reflection is a method that may be used to merge the visual outer surface of a patient with a simultaneous ultrasound scan of the patient’s interior. The technique combines a flat-panel monitor with a halfsilvered mirror such that the image on the monitor is reflected precisely at the proper location within the patient. In this way, the ultrasound image is superimposed in real time ...

This paper presents different solutions for the integration of Video Mediated Communication (VMC) into the home environment considering primarily architectural and technical aspects. The context is entitled comHOME, a concept dwelling of the future designed and built as a full-scale model in collaboration with a telecom operator. The principal problem investigated is the various aspects of priv...

Inclusion of nontraded goods prices has been shown to be partly responsible for slow convergence in price indices across major cities in the United States (Cecchetti et al 2002). Drawing upon insights provided by well known theories, this paper uses panel econometric methods to seek evidence in U.S. city level Consumer Price Index (CPI) data of a systematic long-run relationship between prices ...
