Using Contingent Markdown with Reservation to Profit from Strategic Consumer Behavior

We examine a contingent price markdown (CM) mechanism with guaranteed reservation under which a retailer sells multiple units to forward‐looking consumers who arrive over time according to a Poisson process. During the early part of the selling season, each arriving consumer can either purchase a unit by paying the regular price or reserve a unit at the discount price. Reserved units can only be claimed later when the number of guaranteed reservations meets a pre‐specified threshold, or at the end of the selling season, whichever comes first. Immediately after the number of guaranteed reservations meets the pre‐specified threshold, the retailer will reduce its selling price to the discount price so that all subsequent arriving consumers can take immediate possession by paying the low price. We study the consumer purchasing behavior in equilibrium when the retailer adopts such a selling mechanism, and compare the performance of our mechanism against two benchmarks: fixed price (FP) and pre‐announced discount (PD). Through an extensive numerical analysis, we identify market conditions under which CM dominates both FP and PD in terms of the retailer's revenue and consumer's surplus. Finally, through a fluid approximation to the stochastic model, we simplify the computation of the equilibrium strategy and the optimal revenues, and verify that the key insights obtained from the stochastic model still hold.     

Public opinion towards workfare policies in Europe: Polarisation of attitudes in times of austerity?

Increasing wage inequality, strong labour market divides and welfare retrenchment are widely believed to result in more polarised public opinion towards the welfare state. The present study examined if attitudes towards workfare policies have become more polarised in Europe over recent decades. To achieve this aim, the study analysed public opinion data from the European Value Study (EVS) from 23 European countries in the years 1990–2008, using multi‐level regression analysis. It is found that individuals who are most affected by workfare – the unemployed, the poor and the young – most strongly oppose workfare concepts. Against expectations, there was no evidence of an increasing polarisation of attitudes in Europe. Attitudinal cleavages based on employment status, income and education have remained stable. Differences between age groups have even dissolved because younger cohorts increasingly favour strict workfare policies. The results suggest that warnings of increasing social conflicts and an erosion of solidarity in European societies are exaggerated.     

Avian use of suburban greenways as stopover habitat

Greenways may provide stopover habitat for migrating birds in otherwise inhospitable suburban landscapes. We examined the effect of greenway forested corridor width, vegetation composition and structure, and adjacent land cover on the species richness and abundance of migrating songbirds during spring and fall migration in Raleigh and Cary, North Carolina, USA. Generally, migrating birds were more abundant in wider forest corridors during spring and fall migration. During the spring, migrants were detected more commonly in greenways with taller trees and a higher percentage of hardwood trees. In the fall, migrant richness and abundance was highest in greenways with lower canopy cover, possibly because of the increased vertical complexity of the vegetation at these sites. Forest-interior migrant richness was not correlated with corridor width in either season, but these species were more abundant in greenways bordered by less bare earth and pavement cover in the spring. No other bird groupings were correlated with adjacent land cover measures. Although migrants used greenways of all widths, forested corridors wider than 150 m should be conserved whenever possible to provide stopover habitat for forest-interior migrants. Shrub cover should be retained to maintain vegetative complexity. Habitat for the greatest diversity of migrants can be provided by constructing greenways in areas of lower development intensity and encouraging residents to retain shrubs and trees on properties bordering greenways.

Family Influences on the Social Participation of Youth: The Effects of Parental Social Involvement and Farming

Abstract Parents shape children's social choices through their social and economic actions. Parental social participation connects children to a civic culture and encourages involvement in civic groups. Parents' ties to farming in farm‐dependent communities further enhance children's civic orientations by providing added opportunities and incentives for social participation. Data from the Iowa Youth and Families Project confirm these hypotheses, showing that the children of farmers and of rural leaders are more likely to participate in civic groups. These results establish parental social involvement as a source of social capital and demonstrate the importance of farm influences for understanding the social involvement of youth in rural society.     

Sexuality in Marriage,Dating, and Other Relationships: A Decade Review

In this article, we review the major research advances made during the 1990s in the study of sexuality in marriage and other close relationships. More specifically, we provide a critical review of the empirical findings from the last decade on such sexual phenomena as sexual behavior, sexual satisfaction, and sexual attitudes within the context of marriage, dating, and other committed relationships. After highlighting the major theoretical and methodological advances of the 1990s, we focus on the research literatures of: (1) frequency and correlates of sexual activity in marriage; (2) sexual satisfaction, including its association with general relationship satisfaction; (3) sexuality in gay and lesbian committed relationships; (4) trends in sexual behavior and attitudes in dating relationships; and (5) the role of sexuality in dating relationships. We also incorporate brief reviews of the past decade's research on sexual assault and coercion in marriage and dating and on extramarital sex. We end our decade review with recommendations for the study of sexuality into the next decade.
