This paper introduces consumption externalities into one of the base line models of growth in which continuing expansion of product variety sustains long-term growth. We assume that consumers set a benchmark stock of consumption for each good so that there are commodity-specific external...

We propose a systematic factor analysis approach using the Bayesian Network (BN) framework by taking great advantage of the information conveyed in the large amount of financial data, as well as experts' personal insight and additional evidence. First, we build the BN for a large set of...
