We consider a neoclassical growth model in which the society consists of two classes (capitalists and workers). The capitalists consume part of their income and save the rest, whereas the workers are assumed to consume their entire income immediately without saving anything. The governement can...

The similarity between objects is a fundamental element of many learning algorithms. Most non-parametric methods take this similarity to be fixed, but much recent work has shown the advantages of learning it, in particular to exploit the local invariances in the data or to capture the possibly...

In this paper, we study and put under a common framework a number of non-linear dimensionality reduction methods, such as Locally Linear Embedding, Isomap, Laplacian Eigenmaps and kernel PCA, which are based on performing an eigen-decomposition (hence the name 'spectral'). That framework also...

The purpose of this study was to examine the role of country and technological intensity in the choice of compensation policies, and the influence of such policies on market performance and turnover in high and low technological intensity firms. Using a survey of 602 large firms in three...

Workflows (Wfs) are a major enabling technology for e-commerce. In our research, a Combined Negotiation (CN) is modeled and enacted using Wf technology. The modeling task captures the sequencing of the individual negotiations as well as the dependencies between them, and the enacting task runs...

Software agents (SA) could be useful in forming buyers' groups since humans have considerable difficulty in finding Pareto-optimal deals (no buyer can be better without another being worse) in negotiation situations. Then what are the computational and economical performances of SA for a...

We perform a theoretical investigation of the variance of the cross-validation estimate of the generalization error that takes into account the variability due to the choice of training sets and test examples. This allows us to propose two new estimators of this variance. We show, via...

This study analyzes the impact of career plateau and job characteristics on people's attitudes or behaviors, but it also extends the traditional field of research on career plateau by taking into account the influence of factors linked to job characteristics on the relationship between career...

The Internet and its manifestations, such as electronic commerce or in general network communication between different groups of interest (i.e., agents) have become indispensable for many of us. To adequately use the ever increasing amount of data, attempts are being made to extend data...

We estimate a generalized option pricing formula that has a functional shape similar to the usual Black-Scholes formula by a feedforward neural network model. This functional shape is obtained when the option pricing function is homogeneous of degree one with respect to the underlying asset...
