This paper considers ML estimation of a diffusion process observed discretely. Since the exact loglikelihood is generally not available, it must be approximated. We review the most effcient approaches in the literature, and point to some drawbacks. We propose to approximate the loglikelihood...

Le inchieste nazionali sulla situazione del mercato del lavoro forniscono di solito osservazioni in tempo discreto. Gli individui vengono intervistati in corrispondenza di date distinte, per ognuna delle quali si conosce la loro posizione sul mercato (occupati, disoccupati), ma nulla è noto di...

We analyze the effects of two compound investment options, a shut down and a reopening option, on a Aoki's profit sharing firm organization. Whilst the introduction of a credible threat of shutting down weakens labour's position in the bargaining and favors the shareholders on profit sharing,...

In this paper I consider the estimation of multi-factor exponential affine models of the term structure of interest rates. I start with a survey of the empirical work on the term structure in continuous time, showing that in most cases the implementation of the models has not fully exploited the...

This paper analyzes the effect of the interest rate lower bound on long term sovereign bond spreads in the Euro area. We specify a joint shadow rate term structure model for the risk-free, the German and the Italian sovereign yield curves. In our model, the behavior of long term spreads becomes...

Pricing algorithms are increasingly replacing human decision making in real marketplaces. To inform the competition policy debate on possible consequences, we run experiments with pricing algorithms powered by Artificial Intelligence in controlled environments (computer simulations).In...
