In this work we study the effect of several covariates X on a censored response variable T with unknown probability distribution. A semiparametric model is proposed to consider situations where the functional form of the effect of one or more covariates is unknown. We provide its estimation...

What is a technologically advanced economy? We propose some theoretical elements showing how heterogeneity in the firms' innovation behaviours can be analysed and exploited in order to assess the technological performance of the economy. Three empirical applications using French data are derived...

This paper analyses the pricing behaviour of Luxembourg firms based on survey evidence. Luxembourg firms typically have low market share, many competitors and longstanding customer relationships. Price discrimination is frequently applied. A majority of firms use price review rules that include...

Using nonparametric estimation techniques adapted from Guerre et al. [2000], we infer cost distributions and informational rents, from 666 snow removal contracts offered for tender by the City of Montreal. Our results are compatible with standard received theory of competitive auctions: there is...

Estimation of spatial housing price indices requires a housing market segmentation into local sub-markets. In this paper, we use geographically weighted regression model (GWR) to take account for spatial heterogeneity of housing attribute marginal prices. Estimated marginal prices are then used...

The socio-economic crisis of the mid-1980s experienced by Cameroon has had multiple consequences including unemployment and deterioration of study and supervision conditions in universities. The current situation of universities in Cameroon is characterized by low success rates. The purpose of...
