Response variables that are scored as counts and that present a large number of zeros often arise in quantitative health care analysis. We define a zero-in flated Poisson model with fixed-effects in both of its equations to identify respondent and health-related characteristics associated with...

Summary. This note reconsiders the nonnegative integer-valued bilinear processes introduced by Doukhan, Latour, and Oraichi (2006). Using a hidden Markov argument, we extend their result of the existence of a stationary solution for the INBL(1,0,1,1) process to the class of superdiagonal INBL(p;...

In the literature concerning the geography of new firm formation, explanatory variables pertaining to industrial organization and political economy are seldom considered. Such variables were thus included when investigating what conditions influenced entry of Swedish limited liability firms...

This paper presents a simple approach to deal with sample selection in models with multiplicative errors. Models for non-negative limited dependent variables such as counts fit this framework. The approach builds on a specification of the conditional mean of the outcome only and is, therefore,...

This paper examines the impact of an increase in the school leaving age on high school teachers’ absence behaviour. We estimate differ- ence in difference models of absenteeism using count data approaches. Employing data from the Spanish Labour Force Survey, our findings suggest that high...

There is a growing concern that increased nutrient and sediment runoff from river catchments are a potential source of coral reef degradation. Degradation of reefs may affect the number of tourists visiting the reef and, consequently, the economic sectors that rely on healthy reefs for their...

Patent citation data are used in a growing body of economics and business research on technological diffusion. Until now, there exists little evidence on whether patent citations are a good measure of knowledge flows. Our paper assesses the legitimacy of using European patent citations as a...

We introduce a new method for drawing state variables in Gaussian state space models from their conditional distribution given parameters and observations. Unlike standard methods, our method does not involve Kalman filtering. We show that for some important cases, our method is computationally...

The willingness to pay for a coyote conservation program is estimated using a novel payment-vehicle, based on how many oyotes respondents would be willing to sponsor. This hypothetical scenario mimics an increasingly popular type of actual market. Data from a phone survey conducted in Prince...
