Managing Channel Profits: The Role of Managerial Incentives

The existing literature has examined how manufacturers can enhance profits by employing specific channel structures and channel coordination mechanisms. In this paper, we examine the implications of strategically designed managerial incentives for channel performance in a duopoly. We first analyze how equilibrium outcomes (especially manufacturer profits) are altered when the manufacturers provide their channel managers with strategically designed incentives. Following that, we examine how optimal channel structure decisions are altered when manufacturers provide their managers with strategic incentives, i.e., we examine how strategic incentives moderate optimal channel structure decisions. In contrast with the existing literature, we find that an asymmetric channel structure with one manufacturer employing a profit-maximizing retailer and the other integrated manufacturer providing strategic incentives for the channel manager in charge of pricing, is an equilibrium outcome under certain conditions. We then compare how the implications of strategic incentives differ from those of channel structure decisions and channel coordination initiatives, and discuss when and why strategic incentives yield superior outcomes from the manufacturer’s perspective. Our results shed light on the sparsely researched role of managerial incentives in the channel context.     

Modeling and Forecasting the Sales of Technology Products

Managers in technology product markets require sales response models that provide substantive insights into the effects of marketing activities as well as reliable sales forecasts. Such markets are characterized by frequent introductions and withdrawals of multiple models by different companies. Thus, the data available on the performance of any individual model is scarce. A second characteristic is that the effects of product attributes and marketing activities could change over time as different types of consumers participate in the market at different points in time. Given sparse data, it becomes critical to specify a model that allows pooling of information across brand-models while at the same time providing brand-model specific parameters. We accomplish this via a hierarchical Bayesian model specification. Further, to capture the effects of changing consumer preferences over time, we specify a time varying parameter model. Our modeling framework therefore, integrates a hierarchical Bayesian model within a time varying parameter framework to develop a dynamic hierarchical Bayesian model. We employ data on digital cameras in the U.S. market to estimate the parameters of our proposed model. We use thirty-three months of national level data on the digital camera market with the data series beginning very close to the inception of this product category. We find that while there is little variation in reliance of benefits by early adopters, the second wave of adopters focus on Ease of Use followed by later adopters who rely on Storage and Image Quality. Looking at the elasticities of demand with respect to the various benefits, we find that at around the halfway point of our data series, the industry as a whole would have been better off investing in increasing image quality rather than storage if costs associated with the two are equal. However, at the end of the time horizon both benefits appear to have about equal impact. Further, the relative benefits of improving these attributes vary across brands and points in time. We then generate single period and multiple period ahead sales forecasts. We make different assumptions about information availability and find that the average (across brand-models and time) MAPE ranges from 7.5 to 14.5% for the model. We provide extensive comparisons of our model with 4 potential alternatives and find that our model outperforms these alternatives on the nature of substantive insights obtained as well as in forecasting out-of-sample especially when there is a very short time window of data.     

采用双网络结构的压缩视频超分辨率重建

在实际应用中，为了节省带宽和方便存储，图像和视频通常被下采样和压缩，而降质的图像与视频无法满足人们的实际需求。针对这一问题，采用了一种双网络结构的超分辨率重建方法，首先建立下采视频与压缩后的低分辨率视频的映射关系，然后建立质量增强的压缩视频与原始视频的映射关系，最终在输出端可以得到质量提升的视频帧。在网络中，采用密集残差块来提取压缩视频中丰富的局部分层特征，并结合全局残差学习恢复视频中的高频信息。在压缩环节，采用高性能视频编码来验证所提算法的有效性。实验结果表明，相比于主流的视频编码标准和先进的超分辨率重建算法，所提方法能有效提升编码视频的率失真性能。     

Corporate Public Issue Advertising

This article presents the results of a study of the attitudes of chief executives regarding issue advertising. The study used a set of four issue advertisements representing varying degrees of self-interest. The results indicate marked differences between business leaders in their perceptions of both the usefulness and favourability of different issue advertising messages.     

Exploiting Mobile Technology for Achieving Supply Chain Integration in Indian Retail

For decades supply chain coordination has been subject to research interest, and technology has been seen as an agent that accelerates this process. In developing countries, with far-flung markets and unorganized distribution networks, using technology for improving supply chain performances and accessing information is not an easy task. The research was directed to understand if mobile technology is being used by downstream supply chain partners for information sharing and thus improving supply chain performances. Findings suggest that supply chain integration with suppliers and customers is done through extensive use of mobile networks.     

The ‘Triple-alliance’ perspective for new industry creation: Lessons from the flat panel industry in Taiwan

This paper describes how the development of the microelectronics industry in Taiwan has followed an evolutionary path that eventually led to the formation of the ‘Triple-alliance’. The ‘Triple-alliance’ model postulates that a nation's industrialization is fundamentally underpinned by the arrangement of three distinct institutions: state bureaucracy, domestic business groups and multinational corporations. The paper delineates the role of each participating institution in the context of Taiwan's microelectronics industry, and discusses the interaction between domestic and foreign institutions to demonstrate how the alliance facilitates the transfer and absorption of technology. Using the creation of the flat panel display industry in Taiwan as an example, the paper shows that understanding the interactions among these three institutions is essential for uncovering how technology-intensive industries are created in late-industrializing countries. The paper adopts an evolutionary approach in tracing how the web of linkages and alliances among these three institutions has led to the successful creation of Taiwan's technology-intensive flat panel display industry.     

Representing Heterogeneity in Consumer Response Models 1996 Choice Conference Participants

We define sources of heterogeneity in consumer utility functions relatedto individual differences in response tendencies, drivers of utility, formof the consumer utility function, perceptions of attributes, statedependencies, and stochasticity. A variety of alternative modelingapproaches are reviewed that accommodate subsets of these various sourcesincluding clusterwise regression, latent structure models, compounddistributions, random coefficients models, etc. We conclude by defining anumber of promising research areas in this field.     

Structural Applications of the Discrete Choice Model

A growing body of empirical literature uses structurally-derived economic models to study the nature of competition and to measure explicitly the economic impact of strategic policies. While several approaches have been proposed, the discrete choice demand system has experienced wide usage. The heterogeneous, or mixed, logit in particular has been widely applied due to its parsimonious structure and its ability to capture flexibly substitution patterns for a large number of differentiated products.We outline the derivation of the heterogeneous logit demand system. We then present a number of applications of such models to various data sources. Finally, we conclude with a discussion of directions for future research in this area.
