DURABLE GOODS PRICE CYCLES: THEORY AND EVIDENCE FROM THE TEXTBOOK MARKET

We study the pricing policy of a monopolist selling a durable good with the features of a textbook. We assume buyers differ in their valuation of the good and propensity to resell, and identify the possibility of a positive relationship between the quantity of used goods and the price of a new good, and also a higher price for new goods in the last period before a new edition is introduced. Our empirical analysis supports this model: textbook prices increase as the share of used textbooks increases and the end of the current edition approaches. (JEL D420, L120)     

Step by step: tenant accounts of securing and maintaining quality housing with a housing choice voucher

Previous research on renters’ experiences in the Housing Choice Voucher (HCV) program is robust, but much of it has been conducted in the context of mobility interventions providing added resources. In contrast, this study focuses on HCV renters’ experiences searching for housing without the support of a mobility intervention. In semistructured interviews, 34 HCV renters describe their housing search processes and outcomes. We find that renters struggle to secure housing in their preferred neighborhoods due to limited information and financial costs such as application fees and security deposits. Discussion focuses on practice and policy reforms that might support greater housing choice.     

Educated Immigrant Women Workers Doing Well With Change: Helping and Hindering Factors

The authors investigated the strategies that helped or hindered 10 immigrant women workers to do well with change that affected their work. A total of 182 incidents were extracted and grouped into 9 categories: personal beliefs/traits/ values, taking action, skills/education, personal challenges, self‐care, relationships/ support, government/community resources, work environment, and contextual challenges. Results support and extend contentions that both internal/personal and external factors are key successful adaptation to change for immigrant women. Implications for research and practice are discussed. Counseling recommendations are offered for individuals who are struggling with change.     

Bird diversity in a subtropical South-American City: effects of noise levels,arborisation and human population density

Cities are highly modified environments in which the only areas that resemble natural landscapes are urban parks with low human population density. Attempts are frequently made to maintain high bird diversity in cities for aesthetic or educational reasons. However, it remains unclear whether local site characteristics are important in determining bird assemblage composition or whether simplification of the assemblage is an inevitable consequence of the changes associated with human population density. From May 1998 to December 1999, we undertook bird counts at 521 points in Porto Alegre, Rio Grande do Sul, southern Brazil. Our main goal was to understand the pattern of distribution of the bird species richness and density within the city and determine which variables most affect species assemblages. We recorded 132 species belonging to 43 families that are common in Rio Grande do Sul and obtained quantitative data on 121 species in survey sites. The two most abundant species (House Sparrow, Passer domesticus and Rock dove, Columba livia) were exotics. Analysis based on a reduced subset of 134 points surveyed in spring/early summer suggested that there was a North–south gradient in assemblage structure. Variation in assemblage structure was also affected by the number of trees, urban noise and human population density. However, human population density had a much smaller effect on richness and assemblage structure than variables subject to management, such as tree density and noise levels. These results suggest that complex communities may be maintained in densely populated urban areas of sub-tropical South-America given adequate urban planning.
