We propose a framework covering multi-country and multi-generation diffusion processes. Our model focuses on choice-based diffusion model and we extend the model to incorporate heterogeneity of country. We decompose the choice probability for generation into two components; the first one is...

A direct utility approach can handle multiple discrete/continuous choice outcomes. However, there is a trade-off between allowing correlations between unobserved perceived qualities of two alternatives and computational burden. If we allow the correlations, then we have to do numerical...
