Kalyanam and Shively (1998) and van Heerde et al. (2001) have proposed semiparametric models to estimate the influence of price promotions on brand sales, and both obtained superior performance for their models compared to strictly parametric modeling. Following these researchers, we suggest another semiparametric framework which is based on penalized B-splines to analyze sales promotion effect...

Electronic commerce is an application area still in development, yet research to address fundamental problems such as secure transactions and the “art” of user interfaces has already yielded effective technologies that are used extensively. However, research to address the problem of responsive online sales support has generated few promising approaches. Most electronic catalogs and online shop...

C a retailer who sells perishable seasonal products with uncertain demand. Due to the short sales season and long replenishment lead times associated with such products, the retailer is unable to update demand forecasts by using actual sales data generated from the early part of the season and to respond by replenishing stocks during the season. To overcome this limitation, we examine the case ...

To make effective decisions, consumers, executives and policymakers must make predictions. However, most data sources, whether from the government or businesses, are available only after a substantial lag, at a high level of aggregation, and for a small set of variables that were defined in advance. This hampers real-time prediction. A critical advance in IT research has been the development of...

this study empirically examines whether managers manipulate reported income through the timing of sales of long-lived assets and investments. several empirical implications of the income-smoothing and debt-equity hypothesis in the context of asset sales were tested. the findings are consistent with the timing of asset sales by managers so that the recognized accounting income from these sales s...

We apply Slow Feature Analysis (SFA) to image sequences generated from natural images using a range of spatial transformations. An analysis of the resulting receptive fields shows that they have a rich spectrum of invariances and share many properties with complex and hypercomplex cells of the primary visual cortex. Furthermore, the dependence of the solutions on the statistics of the transform...

This paper evaluates a more integrated approach of regulation when doing international comparisons and represents the first cross-country study in the South American region in which quality and weather variables have been included in the analysis. A total of 82 electricity distribution firms operating in Argentina, Brazil, Chile and Peru have been analysed for the period 1998-2008. Stochastic f...
