This paper uses a variant of the Lotka-Volterra system explaining the dynamic interaction between populations of infected and healthy individuals in which the demographic and epidemiological parameters (the net healthy birth rate, the death rate of the infected and the infection rate) are...

We consider the links between the health structure of the population and The productive system of an economy which is subject to infectious disease, in particular tuberculosis. Reviewing the models of tuberculosis suggests that a Lotka-Volterra system can capture the dynamics of epidemics. We...

This paper considers the joint investment and labour contracts (employment and wage compensation) for a firm which has private information over its expost revenues. There is costly state observation for investors in the firm; workers can free ride on any investors state observation. The...

We use a simple Lotka-Volterra model of the disease transmission process to analyse the dynamic population structure in two scenarios. Firstly a vaccine is available\ on the market at a constant price through time. Secondly, the vaccine is publicly provided. The vaccine works either by giving...

Environmental quality and economic development are often thought to be causally linked. This paper empirically examines the impact of economic growth and international environmental treaties on air pollution emissions in several transition countries using panel data analysis. The results...

The remarkable growth of older population has moved long term care to the front ranks of the social policy agenda. Understanding the factors that determine the type and amount of formal care is important for predicting use in the future and developing long-term policy. In this context we jointly...

It is evaluated that, each year, 35% out of the 10 million hospital admissions in Italy take place outside the LHAs of residence. In our paper we try to give an explanation of this phenomenon making reference to the social gravity model of spatial interaction. We estimate gravity equations using...

This paper considers a regression model with a log-transformed dependent variable. The log transformed model is estimated by simple least squares, but computing the conditional mean of the dependent variable on the original scale given the explanatory variables analytically requires knowing the...

Internationally comparable panel data from the full eight waves of the ECHP are used to study the effects of health on retirement in nine EU countries. Self-reported retirement is compared to a broader measure of inactivity. Measures of health include two latent stock measures, one that is...
