Recently, retailers have begun considering which brands they can delist without reducing customer satisfaction, losing category sales, or increasing store switching behavior. Although several studies have considered assortment reductions, none has explicitly investigated the impact of total...

The recent episodes of capital flows to emerging market economies in the aftermath of the global financial crisis once again highlighted the importance of appropriate policy design to cope with strong and volatile capital flows, that are effective not only during surges but also during...

This paper aims to understand the role of investment shocks in explaining output fluctuations observed in Turkish economy. For this purpose a small open economy DSGE model is estimated on Turkish data for 2002:1-2012:2 period by Bayesian methods. Variance decomposition analysis shows that...

As an emerging economy, Turkey is an interesting case study because it was one of the hardest hit countries by the crisis, with a year-over-year contraction of 15 percent during the first quarter of 2009. At the same time, anticipating the fallout from the crisis, the Central Bank of the...

This research provides a new way to validate and compare buy-till-you-defect [BTYD] models. These models specify a customer’s transaction and defection processes in a non-contractual setting. They are typically used to identify active customers in a com- pany’s customer base and to predict...

We introduce an international, adaptive diffusion model that can be used to forecast the cross-national diffusion of an innovation at early stages of the diffusion curve. We model the mutual influence between the diffusion processes in the different social systems (countries) by mixing...

Buy-till-you-defect [BTYD] models are built for companies operating in a non- contractual setting to predict customers’ transaction frequency, amount and timing as well as customer lifetime. These models tend to perform well, although they often predict unrealistically long lifetimes for a...
