Decomposing Granger causality over the spectrum allows to disentangle potentially different Granger causality relationships over different frequencies. This may yield new and complementary insights compared to traditional versions of Granger causality. In this paper, we compare two existing...

Marketing researchers often assume that innovation diffusion is affected by social contagion. However, there is increasing skepticism about the importance of contagion and, as has long been known, S-shaped diffusion curves can also result from heterogeneity in the propensity to adopt. To gain...

The problem of optimal decision among unit roots, trend stationarity, and trend stationarity with structural breaks is considered. Each class is represented by a hierarchically random process whose parameters are distributed in a non-informative way. The prior frequency for all three processes...

In this paper, we consider the decision-making and coordination mechanism of a seasonal product supply chain channel with a low season and a high season, where the price of the final product is strictly regulated, and the raw material is subject to price cap regulation in the high season. The...

This paper provides a new and complementary explanation for a pricing puzzle for seasonal products, namely, counter-cyclical pricing, drawing on the category-expansion effects of price promotions. Our study emphasizes the seasonal fluctuation in promotion frequency rather than the change in...

The dual model with diffusion is appropriate for companies with continuous expenses that are offset by stochastic and irregular gains. Examples include research-based or commission-based companies. In this context, Avanzi and Gerber (2008) showed how to determine the expected present value of...
