We analyze the role of training in mitigating the negative impact of technical and organizational changes on the employment of older workers. Using a panel of French firms in the late 1990s, our empirical analysis confirms that new technologies and some innovative workplace practices are biased...

It is well-known that the market prices of options produce implied volatilities that inexplicably vary by exercise price in a pattern often referred to as the volatility smile. This paper shows that not only do market prices produce volatility smiles, but so do model prices. This result occurs...

Computers are an important part of modern education, yet large segments of the population – especially low-income and minority children – lack access to a computer at home. Does this impede educational achievement? We test this hypothesis by conducting the largest-ever field experiment...

Any mortality analysis is faced with the difficulty of dealing with large quantities of noisy data. Pragmatic approaches have ever relied on graphical analysis of mortality contour maps in order to identify age, period and cohort effects. We adapt and apply suitable methods of image processing...

Parallel computation is a fast growing computing environment in many areas including computational Bayesian statistics. However, most of the Bayesian parallel computing have been implemented through the sequential Monte Carlo method where model parameters are updated sequentially and it is...

Does computerization increase or reduce the extent of skills that workers are required to have? The authors argue that the effects of computer-based technologies (CBT) are neither universal nor uniform. Rather, effects depend on the level of skill required by occupations prior to the...

Simulation, visualisation and visual computing are key research areas that are currently only partially covered in the past ICT Programmes of the European Commission. VISION has been funded by the European Commission to deliver a study in the field of "simulation, visualisation and visual...
