This chapter considers several important areas of response (or nonresponse) of banking regulation to the crisis. I begin with an overview of the causes of the crisis and the ways in which the crisis has highlighted the need for regulatory reform. I review the prospects for the reform of regulatory content. I also consider and evaluate the potential changes in the structure of regulation and supervision coming out of the crisis.
The diffusion of an innovation is governed by, among other things, word of mouth. In social systems, growth processes are considered strongly influenced by people who have large number of ties to other people. In the social network literature, such people are called influentials, opinion leaders, mavens, or sometimes hubs. Furthermore, when the marketing literature addresses such people, the focus is typically not on how they influence the overall market but rather on either assessing their influence on people they are in direct contact with or identifying their characteristics.
Cross-selling is becoming an increasingly prevalent practice in call centers, due, in part, to its unique capability to allow firms to dynamically segment their callers and customize their product offerings accordingly. This paper considers a call center with cross-selling capability that serves a pool of customers that are differentiated in terms of their revenue potential and delay sensitivity. It studies the operational decisions of staffing, call routing, and cross-selling under various forms of customer segmentation.
We develop a competitive pricing model which combines the complexity of time-varying demand and cost functions and that of scale economies arising from dynamic lot sizing costs. Each firm can replenish inventory in each of the T periods into which the planing horizon is partitioned. Fixed as well as variable procurement costs are incurred for each procurement order, along with inventory carrying costs. Each firm adopts, at the beginning of the planning horizon, a (single) price to be employed throughout the horizon.
This paper examines liquidity and how it affects the behavior of mutual fund portfolio managers, who account for a significant portion of trading in many assets. We define an asset to be perfectly liquid if a portfolio manager can trade the quantity she desires when she desires at a price not worse than the uninformed expected value. A portfolio manager is limited by both what she needs to attain and the ease with which she can attain it, making her sensitive to three dimensions of liquidity: price, timing, and quantity.
Accumulating evidence suggests that targets' displays of emotion shape perceivers' impression of those targets. Prior research has highlighted generalization effects, such as an angry display prompting an impression of hostility. In two studies, we went beyond generalization to examine the interaction of displays and behaviors, finding new evidence of augmenting effects (behavior-correspondent inferences are stronger when behavior is accompanied by positive affect) and discounting effects (such inferences are weaker when behavior is accompanied by negative affect).
This chapter examines how the original tenets of the affect-as-information hypothesis can be extended to explain a wide range of judgment phenomena, especially with respect to consumer decision making. To this end, research within social psychology as well as research from other fields such as consumer behavior and behavioral decision making is reviewed. The chapter is organized into three main sections. The first section identifies distinct types of information that people seem to derive from their feelings.
Recent empirical evidence supports the view that the income process has an individual-specific growth rate component [Baker (1997), Guvenen (2007b), and Huggett, Ventura, and Yaron (2007)]. Moreover, the individual-specific growth component may be stochastic. Motivated by these empirical observations, I study an individual's optimal consumption-saving and portfolio choice problem when he does not observe his income growth. As in standard income fluctuation problems, the individual cannot fully insure himself against income shocks.
This important handbook explores new and emerging directions in both brand management research and practice and encompasses a diverse set of approaches. These include the latest academic research to offer new frameworks for understanding brand management. Contributors offer the researcher's perspective on current tools in practice by brand managers today and new research and conceptual frameworks for understanding and managing customer experiences.
