We show how small to medium sized cities can make use of the cellular automata (CA) approach to integrate land use data and other GIS based data with inter-active scenario evaluation. In our model development we put particular focus on the interdependency between transport infrastructure supply...

A two stage bargaining model is developed to describe how fertility decisions are made in a strategic family setting. Given the assumption that family contracts are incomplete and cannot be used to enforce optimal behavior, it is shown that investments in children (i.e. the fertility rate) may...

However, the Aaron condition as usually stated is not precise enough about the exact form of the PAYG pension system. PAYG pension systems can be either of the defined-benefit or...

Three theoretical benchmark models of diffusion of new technologies are the substitution, mortality and social-learning models. These models tend to generate symmetric, right-skewed and left-skewed S-curves respectively. The empirical literature has focused primarily on fitting either Logistic...

Faced with an ageing population, governments are shifting the financial responsibility for retirement to their citizens. Employers, too, are shifting this responsibility to employees, with most now offering defined-contribution retirement plans. Yet it is widely acknowledged that consumers do...

It is common for comparisons to be made of output growth and inflation across groups of countries, yet such comparisons can result in inconsistencies. We address two problems: (i) how to measure aggregate real output and inflation for groups of countries and (ii) how to construct measures of...
