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...

Most forecasting models often fail to produce appropriate forecasts because they are built on the assumption that data is being generated from only one stochastic process. However, in many real world problems, the time series data are generated from one stochastic process initially and then...

Inconsistent data frequency is a common problem in many research fields; therefore, it should be handled before a particular study is well under way. Many novel ideas including disaggregation techniques, which are the major interest of this study, have been suggested to mitigate the nuisances of...

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...

Different data frequency is a common problem in many research fields; therefore, it should be handled before a particular study is well under way. Many novel ideas including disaggregation techniques, which are the major interest of this study, have been suggested to mitigate the nuisances of...

This empirical paper compares the forecasting accuracy of a two-stage MNL model with that of an ordinary MNL model. The explanatory variables used in this study include individual choice set and physiological responses of the subject. Designed experiment was conducted to acquire the choice set...

Investing in micro-loan market has become one of the most famous instrument in alternative finance due to the fact that its rate of return is comparable to other risky financial instruments and it places investors in the position of philanthropists and induce “enjoyment”. In terms of...

Consumer's preference structure varies across product categories. For some durable goods, such as laptops and smartphones, consumers tend to distinguish a product from its competing ones by differences in several features ordered in their importance. Under this preference tructure, so called...

In preceding research, an assumption about the independence of interpurchase time was made. Interpurchase time was assumed to be extracted independently from a particular distribution. However, autocorrelation is observed in interpurchase time and about 30% of the individuals' interpurchase time...

We analyze the effects of non-financial incentives that provide relative performance feedback on judgmental forecasting performance. Using a controlled laboratory experiment, we find that the provision of such non-financial incentives improves judgmental forecasting accuracy, especially when...
