Retailing and media platforms recommend two types of items to their users: sponsored items that generate ad revenue and nonsponsored ones that do not. The platform selects sponsored items to maximize ad revenue, often through programmatic auctions, and nonsponsored items to maximize user utility with a recommender system (RS). We develop a binary integer programming model to allocate sponsored recommendations considering dual objectives of maximizing ad revenue and user utility. We propose an algorithm to solve it in a computationally efficient way. Our method is a form of postfiltering to a traditional RS, making it widely applicable in two-sided markets. We apply the algorithm to data from an online grocery retailer and show that user utility for the recommended items can be improved while reducing ad revenue by a small amount. This multiobjective approach unifies programmatic advertising and RS and opens a new frontier for advertising and RS research. We provide an extended discussion of future research topics. 相似文献

Given the importance of the Machiavellianism construct on informing a wide range of ethics research, we focus on gaining a better understanding of Machiavellianism within the whistle-blower context. In this regard, we examine the effect of Machiavellianism on whistle-blowing, focusing on the underlying mechanisms through which Machiavellianism affects whistle-blowing. Further, because individuals who are higher in Machiavellianism (high Machs) are expected to be less likely to report wrongdoing, we examine the ability of an organization’s ethical environment to increase whistle-blowing intentions of high Machs. Results from a sample of 116 MBA students support our premise that Machiavellianism is negatively related to whistle-blowing. Further, we find that Machiavellianism has an indirect effect on whistle-blowing through perceived benefits and perceived responsibility. Finally, we find that a strong ethical environment, relative to a weak ethical environment, increases whistle-blowing intentions incrementally more for individuals who are higher in Machiavellianism. Taken together, these findings extend our understanding of how Machiavellianism and an organization’s ethical environment impact whistle-blowing. 相似文献

This article reports findings from an indepth evaluation of extra care housing (a form of assisted living positioned between sheltered housing and care homes) for older people in the UK. The information presented is a significant improvement on that previously in the public domain. The authors conclude that a careful reappraisal of cost components and a more integrated approach across housing, health and social care is required, particularly in a climate of public funding cuts. 相似文献

Our objective is to assess whether dynamics hinder or assist co-ordination in a game with strategic complementarities. We study two dynamic aspects: different agents make decisions at different points in time; and extra information about a payoff-relevant state of nature becomes available over time. We find that the dynamic resolution of information matters most for uniqueness of equilibrium. This is demonstrated by showing that the condition for uniqueness is weaker when learning occurs. We also analyse how successfully agents co-ordinate when there is a unique equilibrium. Finally, we show that path dependence occurs: the order in which signals arrive matters, as well as the total amount of information received. 相似文献

What did Medicare do? The initial impact of Medicare on mortality and out of pocket medical spending
We study the impact of the introduction of one of the major pillars of the social insurance system in the United States: the introduction of Medicare in 1965. Our results suggest that, in its first 10 years, the establishment of universal health insurance for the elderly had no discernible impact on elderly mortality. However, we find a substantial reduction in the elderly's exposure to out of pocket medical expenditure risk. Specifically, we estimate that the introduction of Medicare was associated with a 40% decline in out of pocket spending for the top quartile of the out of pocket spending distribution. A stylized expected utility framework suggests that the welfare gains from such reductions in risk exposure alone may be sufficient to cover almost two-fifths of the costs of Medicare. These findings underscore the importance of considering the direct insurance benefits from public health insurance programs, in addition to any indirect benefits from an effect on health. 相似文献

The following is a report of a study designed to measure advertising content based on the cognitive and affective elements of informational (i.e., information processing) and transformational (i.e., experiential) content using the measure of advertising informational and transformational content developed by Puto and Wells (1984). A university hospital advertising campaign designed to be high in transformational content did not appear to affect perceived quality of local university hospitals relative to private hospitals or increase the likelihood of choosing a university hospital in the future. Further, experiences with university hospitals that seemed to be in direct contrast to the content of the advertisements based on subject perceptions affected how university hospital advertisements were perceived in terms of content. Conclusions and implications for hospital advertising campaigns are discussed. 相似文献

Multivariate models are developed to explain the differential occupancy performance of a sample of 279 English hotels. Following a procedure established in an earlier paper, hotels are first differentiated on the basis of their overall occupancy performance, seasonality, long‐term trend and length of season. Regression models are specified and calibrated to relate each of these dimensions of occupancy performance to the location and other characteristics of the hotels. The four models produce the expected positions of hotels in ‘occupancy performance space’, against which their observed positions can be compared. The application of the models in hotel marketing is discussed and demonstrated. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

We decompose earnings risk into contributions from hours and wage shocks. To distinguish between hours shocks, modeled as innovations to the marginal disutility of work, and labor supply reactions to wage shocks, we formulate a life-cycle model of consumption and labor supply. For estimation, we use data on married American men from the Panel Study of Income Dynamics. Permanent wage shocks explain 31 percent of total risk, permanent hours shocks 21 percent. Progressive taxation attenuates cross-sectional earnings risk, but its life-cycle insurance impact is much smaller. At the mean, a one-standard-deviation hours shock raises lifetime income by 11 percent, a wage shock by 13 percent. 相似文献
