This article analyses cartels that act as a Stackelberg leader with respect to a competitive fringe in industries supplying differentiated products. The main objectives are to investigate how cartel stability changes with the degree of differentiation and the cartel size, to predict endogenous...

Voting Power Indices enable the analysis of the distribution of power in a legislature or voting body in which different members have different numbers of votes. Although this approach to the measurement of power, based on co-operative game theory, has been known for a long time its empirical...

This paper considers a class of two-player dynamic games in which each player controls a one-dimensional variable which we interpret as a level of cooperation. In the base model, there is an irreversibility constraint stating that this variable can never be reduced, only increased. It otherwise...

This thesis develops several Generalized Method ofMoments (GMM) estimators for analysing Not Missing at Random (NMAR) data, which is commonly referred to as the self-selection problem in an economic context. We extend the semiparametric estimation procedures of Ramalho and Smith (2003) to...

The aim of this thesis is to investigate Generalised Empirical Likelihood (GEL) and related informational theoretical methods for estimation and inference of parameters of models that satisfy unconditional and conditional moment restrictions. Three topics in this field are studied. Firstly, the...

This paper introduces a class of survival models for discrete time-to-event data with random right censoring. Flexible distributions for the survival times are constructed by modelling the random survival functions as discrete-time beta-Stacy processes (DBS) and by introducing the regression...

Using individual patient data from five independent surveys, we evaluate regional variations in survival in cerebral palsy. The influence of four important variables measuring disability, which are only partially observed for many cases, are analysed. Results are compared between a naive...

When modeling the hazard of entry into marriage, the non-monotonic dependence on age needs to be taken into account. In this paper, nonlinear discrete-time hazard models based on a bell-shaped function are proposed, in which the support of the hazard function, the maximum hazard and the age of...

We consider the problem of representing claims for coherent risk measures. For this purpose we introduce the concept of (weak and strong) time-consistency with respect to a portfolio of assets, generalizing the one defined in Delbaen [7]. In a similar way we extend the notion of m-stability, by...
