Generalized linear latent variable models (GLLVMs), as defined by Bartholomew and Knott, enable modelling of relationships between manifest and latent variables. They extend structural equation modelling techniques, which are powerful tools in the social sciences. However, because of the complexity of the log-likelihood function of a GLLVM, an approximation such as numerical...

En finance, le but d'un investisseur confronté à une construction de portefeuille est de trouver quelle combinaison d'actifs produira, dans le futur, le meilleur rendement possible, et cela pour un risque donné.

In most health survey the state of health of individuals is measured through several different kinds of variables such as qualitative, discrete quantitative or dichotomic ones. From these variables, one aims at building univariate indices of health that summarize the information. To do so, we propose in this paper to use Generalized Linear Latent Variable Models (GLLVM) (see e.g....

The effects of active labour market policies (ALMP) on individual employment chances and earnings are evaluated by nonparametric instrumental variables based on Swiss administrative data with detailed re-gional information. Using an exogenous variation in the participation probabilities across fairly autono-mous regional units (cantons) generated by the federal government, we...

In the context of the negotiations on the Free Trade Area of the Americas (FTAA), it has been proposed that signatories agree to enact and enforce a national law against private anti-competitive practices. This paper assesses the feasibility and desirability of such an initiative. The paper starts by documenting and discussing the experience with national anti-cartel enforcement in...

To establish a benchmark, the cross border mergers and acquisitions wave of the late 1990s is compared to its predecessor in the late 1980s. It is found to be at least five times larger (in real terms), to involve firms from more OECD nations, and to include many more service sector transactions. However, in comparison to the size of national stock market capitalizations, foreign...
