Who benefits from privileged peers? Evidence from siblings in schools

By comparing siblings attending the same school at different points in time, we investigate whether the effect of peer quality on long-term labor market outcomes varies with parental background. We find that exposure to better peers—who have higher mean parental education—increases lifetime earnings of disadvantaged students, coming from families with low parental education, but penalizes privileged students from better educated families. These results suggest that desegregation policies that allocate disadvantaged students to schools with better peers produce long-term benefits. We discuss mechanisms and show that human capital accumulation, ordinal rank and network effects contribute to explain our findings.     

THE ECONOMIC AND BEHAVIORAL CONSEQUENCES OF ONLINE USER REVIEWS

Online user reviews have become an increasingly relevant informational tool during product search and adoption. Recent surveys have shown that consumers trust and rely on online reviews more than they do on website recommendations and experts opinions. As a new way of driving consumer purchasing intentions, online user reviews have therefore come under scrutiny by researchers. The objective of this paper is to offer an overview of the literature regarding the impact of online user reviews on economic indicators (e.g., sales, marketing strategies) and on consumer behavior. Furthermore, following the growing interest of academics and professionals alike on the topic, the present work provides an exploratory analysis of the consequences of online reviews on individual rating behavior – empirical regularities showed that online rating distributions tend to be concentrated on extreme values, possibly because of rating biases. As consumers and firms incorporate the heuristic cues from such distributions into their decision-making processes, biased ratings might lead to suboptimal choices. This overview presents established results (e.g., the impact of volume on product sales) and insights as issues for future research.     

Precautionary retirement and precautionary saving

The paper analyzes the lifetime utility maximization problem of an agent who chooses her saving and timing of retirement in the presence of labor income risk in a simple setting where a pure redistributive pension scheme is in place. In this context, a precautionary motive for retirement, which pushes old workers to replace an uncertain labor income with certain pension payments, and to retire early is identified. The conditions for precautionary retirement and saving to arise are then characterized and interpreted in two settings. In the first setting, utility only depends on income, and a sufficiently low level of absolute prudence is necessary for precautionary retirement. A sufficiently high level is necessary however for precautionary saving, which can coexist with precautionary retirement only for intermediate values of absolute prudence. In the second setting, agent utility also depends on leisure, and three conditions allow the precautionary motive for retirement and saving to jointly operate: prudence, an index of absolute prudence sufficiently low and cross-prudence in leisure.     

Earnings Instability and Tenure

We study the effect of tenure on earnings instability in Italy using the reforms of temporary employment contracts, which affected the average tenure of workers differentially across cohorts. We develop a model of earnings dynamics, and we exploit the variation of tenure and instability over time and across birth cohorts to estimate policy‐relevant parameters. Our results indicate that each year of tenure on the job reduces earnings instability by 11 percent; the drop is faster in the first three years of the match. Workers on a temporary contract have an earnings instability up to 100 percent higher than workers on a permanent contract.     

Planning in Turbulent Times: Exploring Planners' Agency in Jerusalem

This article explores the role of planning in the deeply divided and politically polarized context of Jerusalem. The overall argument developed throughout the article is that the relation between planning and politics is a non‐hierarchical set of interactions, negotiated within specific historical, geographical, legal and cultural contexts—in other words, orders don't come down from the politicians to be slavishly followed by planners. In this respect our findings, based on in‐depth interviews with Israeli planners, suggest that the case of Jerusalem represents a particularly dramatic illustration of the fact that the function of planning expertise can only be understood in relation to the surrounding socio‐political environment. Furthermore, contrary to conventional wisdom, planners in Jerusalem are not destined to either complicity or irrelevance in the face of political imperatives; planners' agency, however, does not simply reflect their mastery of specific professional knowledge and tools, but also their ability to act strategically in relation to the context in which they operate.     

Spillovers from agglomerations and inward FDI: a multilevel analysis on sub-Saharan African firms

This paper adopts multilevel analysis to study the agglomeration-performance nexus for domestic firms in sub-Saharan Africa. We show that contextual factors can explain up to 30 % of the variance in firms’ productivity, more than half of which depends on the geographic location. Our results show also that African firms’ productivity is positively correlated to the size of the agglomeration when they locate in larger cities specialized in different sectors, while the relation turns negative when they face direct competition from firms in the same industry. These effects are similar in the services and the manufacturing industries, even if in the latter positive spillovers are found to be conditional to the presence of backward and forward linkages with nearby firms. Finally, we are able to show that these effects are also confirmed when domestic firms locate close to foreign multinationals, especially those coming from the South.     

The relevance of the tangible and intangible social impacts of tourism on selected South African communities

Most tourism social impact studies emphasise tangible social impacts such as economic improvement. In developing countries such as South Africa, a small percentage of tangible benefits filter down to community level. This creates a problem as various studies revealed the importance of community support for the sustainability of the tourism industry. Therefore it was important to explore the role of both the tangible and the intangible social impacts of tourism. Communities with established tourism industries (Clarens, Soweto and Jeffreys Bay) formed part of the quantitative research. Through exploratory factor analyses, 31 social impact statements could be categorised into four tangible and two intangible impacts. The tangible factor Economic improvement obtained a low rating, meaning that it was not directly experienced by residents, while the intangible factor Community pride and upliftment obtained the highest rating among all factors. This, together with the fact that community members continue their support for the tourism industry, is a novel find, indicating the significant role of intangible social impacts in fostering community support. This finding shows the importance of incorporating intangible social impacts into tourism planning in developing countries. Contributions are made towards social impact research methodology and literature.
