Vertical product differentiation and two-sided markets 总被引:1,自引:0,他引:1
We model platform competition in a market where products are characterized by cross network externalities. Consumers differ in their valuation of these externalities. Although the exogenous set-up is entirely symmetric, we show that platform competition induces a vertical differentiation structure that allows for the co-existence of asymmetric platforms in equilibrium. We establish this result in two set-ups: in the first one platforms commit to prices, in the second one they commit to network sizes. 相似文献

Research examining the effects of store environment on shoppers has found that a number of atmospheric cues have significant effects on shoppers' cognitive, affective, and behavioral responses. To date, retail atmospheric cues have been studied in isolation, instead of simultaneously, like they occur in the retail setting. This study examines the interactive effects of two atmospheric cues—retail density and music tempo—and their impact on shopper responses within a real shopping environment. Based on the schema incongruity model, it is found that shopper hedonic and utilitarian evaluations of the shopping experience are highest under conditions of slow music/high density and fast music/low density. Significant main effects of music tempo are found for behavioral responses such as approach/avoidance tendency and extent of browsing behavior. The results underscore the need to examine interactive effects of atmospheric cues to better understand the impact of the store environment on shoppers. © 2005 Wiley Periodicals, Inc. 相似文献

Abstract We estimate the increased mortality and term life insurance costs for women who have a family history of breast or ovarian cancer. Using data from the medical literature on age-specific and family history-specific incidence rates, we develop double-decrement models to evaluate the actuarial impact of breast cancer and ovarian cancer in the family. We also calculate the increased mortality and term insurance costs for women who test positive for the BRCA1 or BRCA2 gene mutation. We find that the type of affected relative and her age at onset of the disease are key underwriting factors. We find substantial mortality increases (up to 100%) for women with two relatives with cancer and women with a first-degree relative who developed cancer at an early age. Mortality increases for women with the BRCA gene mutation reach 150%. While some females with a family history of cancer can be accepted at standard rates, others may need to be quoted substandard rates, depending on the underwriting policy of the company. Females with the gene mutation can possibly be accepted at a rate that incorporates a severe mortality surcharge. 相似文献

Risk-neutral compatibility with option prices 总被引:1,自引:0,他引:1
A common problem is to choose a “risk-neutral” measure in an incomplete market in asset pricing models. We show in this paper
that in some circumstances it is possible to choose a unique “equivalent local martingale measure” by completing the market
with option prices. We do this by modeling the behavior of the stock price X, together with the behavior of the option prices for a relevant family of options which are (or can theoretically be) effectively
traded. In doing so, we need to ensure a kind of “compatibility” between X and the prices of our options, and this poses some significant mathematical difficulties. 相似文献

Abstract This paper studies the normative problem of redistribution between individuals who differ in their lifespans. We discuss aspects related to the objective function and argue that aversion to multiperiod inequality should be taken into account. Then, we study the properties of the social optimum both with full information and with asymmetric information. We highlight the role of aversion to multiperiod inequality and show that it has substantial consequences on the design of Social Security schemes. In particular, we show that for a low (resp. high) aversion to multiperiod inequality, a negative (resp. positive) implicit tax rate on continued activity is desirable. 相似文献

This article analyses the evolution of employment in the French regions, putting the accent on business service firms. A ‘shift and share’ type of analysis shows that a primary decentralisation in tertiary activities seems to emerge in the 1990s, essentially pertaining to ancillary producer services. An explanatory analysis backs up the general validity of the regional economic base theory: the basic activities, to which business services can quite legitimately be attached, certainly play a leading long-term role on global employment dynamics. Finally it shows that over the past 20 years, the regional offer of services to businesses has been the major discriminating variable between regions, greatly influencing the evolution of basic employment and thus confirming the vital driving force of this sector in regional dynamics. 相似文献

A refinement of the construct of age, specifically ‘older’, is recognised as a critical measurement concern for experts in both ageing research and policy formation. In this context, we set out to both chronologically define an ‘older worker’ and to identify on what basis the age of ‘older’ is determined. In doing so, we draw on open‐ended survey data (collected in 2011) from a sample of 407 organisational decision makers across all industries in Ireland. Our focus was specifically on the perspective of organisational decision makers because these individuals will be instrumental in facing the challenges associated with workforce ageing. The results show that workers are considered as ‘older’ at a younger age than might be expected and that decision makers conceptualise workers as ‘older’ using various approaches in the organisational context. Our findings contribute to the literature in three ways: firstly, by providing an important empirically derived understanding of the term ‘older worker’; secondly, by empirically examining previously suggested ‘possible’ indicators of age; and thirdly, by demonstrating that these indicators are conceptually and empirically distinct, advancing theory on the concept of age in the workplace. 相似文献

Most organ transplants are from dead donors. National transplant organizations exhibit considerable differences in terms of their donor population rates. Spain's organization is by far the most efficient in this respect. We argue that much of the productivity advantage of Spain's transplant organization proceeds from an efficient organization of the production chain, from organ procurement to transplantation. Transplants from dead donors are analogous to a common resource for the transplant community. Their circulation through the national transplant organization creates public good externalities between the care units in charge of organ retrieval and those in charge of transplantation. A socially efficient production of transplant care services obtains through an optimal control, by the national transplant agency, of both the circulation and the production of transplants. In particular, transplant shortage makes the rotten kid theorem fail in this context. The analysis also produces a natural measure of public good externalities, evaluated from the standpoint of care units. 相似文献

Abstract Hunting participation, as indicated in the 1983 Nationwide Recreation Survey, is examined to determine the relationship between age of first hunting experience and adult level of participation. A statistically significant association between these two variables is found. In addition, more than 83 percent of those who hunt began their involvement by 18 years of age. The findings have implications for future hunting participation and the provision of programs for hunters. 相似文献

For years, policymakers, business leaders, human resources professionals, and economists have attempted to explain the existence of unemployment. Unemployment inhibits the economic growth of a nation and contributes to the problem of ongoing poverty, which cannot be lessened without that growth. Understanding the causes of unemployment and developing policies and programs to decrease it are vitally important for nations around the world, but one key variable in the study of unemployment has been overlooked. That variable is culture. This article will show that culture can significantly explain cross‐national differences in unemployment rates and offers a link to understanding the global problem of poverty that plagues nations today. © 2012 Wiley Periodicals, Inc. 相似文献
