In this paper a count data regression model accounting for endogenous censoring with household specific censoring thresholds is presented. The presented modelling approach is utilized in an analysis of household choice of total number of nights to spend on monthly recreational trips. The...

The paper empirically studies whether pharmaceutical firms use advertising as a signal for high quality drugs. A multiple random effects count data hurdle model is specified and a simulated maximum likelihood estimation approach is developed and utilized in the empirical analysis

We focus on the testing of a unit root in the integer-valued autoregression of order one. Finite sample distributions for a Dickey-Fuller test of a random walk with drift with Poisson distributed and, hence, skewed errors are obtained by Monte Carlo simulation

Central banks have been made more independent in many countries. A common rationale has been the existence of a credibility (or lack-of-trust) problem for monetary policy. This indicates a possible and until now unexplored link between social trust and central-bank independence. Our empirical...

Households' choice of the number of leisure trips and the total number of overnight stays is empirically studied using Swedish tourism data. A bivariate hurdle approach separating the participation (to travel and stay the night or not) from the quantity (the number of trips and nights) decision...

This paper is a first empirical attempt to investigate why politicians around the world have chosen to give up power to independent central banks, thereby reducing their ability to fine-tune the economy. A new data-set covering 132 countries, of which 89 countries had implemented such reforms,...
