Field Experiment Tests for Discrimination against Hispanics in the U.S. Rental Housing Market

This article tests for discrimination against Hispanics in the U.S. rental housing market using e‐mail correspondence with landlords advertising units online. We divide Hispanics into two groups: those that appear assimilated into American culture and recent immigrants. We find little difference in the treatment of assimilated Hispanics and whites; however, Hispanics we portray as recent immigrants receive less favorable treatment with margins of net discrimination as large as 6.89% of landlords. We also find discrimination varies significantly at the region level and by the ethnic composition of neighborhoods.     

The Impact of DC Pension Systems on Population Dynamics

Abstract

This study investigates the risk inherent in defined contribution (DC) pension plans on an individual and aggregate basis, based on U.S. data. Our aim is to gain insight into the consequences of a DC pension scheme becoming the predominant pillar of retirement income for an entire society. Using the stochastic simulated output of a DC flexible age-of-retirement model, we first determine the optimal investment strategies. We then examine the demographic retirement dynamics of an entire population of DC pension plan participants.

We observe that even for the most risk-averse plan members there is a high level of uncertainty in an individual’s age at retirement. At the aggregate population level, we find that this uncertainty does not get dampened to any great extent by a diversification effect. Instead, the central role played by the market in determining retirement dates results in significant variation in the dependency ratio (the ratio of retirees to workers) over time. In addition, an attempt to ameliorate the outcome by introducing additional realistic features in the DC population modeling did little to dampen this volatility, which suggests that countries dominated by DC schemes of this type may, over time, be exposed to significant risk in the size of its labor force.     

Training in service – importing and imparting customer service culture as an interactive process

Customer service culture initiatives have received renewed academic attention. Recent surveys of employee responses have highlighted the importance of training. However, its precise nature and how messages and various responses are mediated through an interactive and dynamic process have been largely neglected. In addition, employees' experience of customer service as consumers and of its contradictions has yet to be fully explored in accounting for employee responses. In an effort to develop existing knowledge and models of customer service culture, these issues are addressed by drawing on observational research. Four training programmes are examined in varied contexts, including a UK call centre and a Malaysian bank. They reveal a dynamic whereby trainers' anticipation of employee attitudes such as cynicism and the immediate reactions and dialogue of trainees help shape both the service message and subsequent responses.     

Science,Technology and the Quest for Sustainable Development

The quest for sustainable development is seen in this article as an intrinsic part of the reconstitution of environmentally-oriented science and technology policy that has been taking place over the past 15 years in most European countries. Rather than dealing with environmental problems after they have occurred, the trend is increasingly to base environmental research and development on so-called preventive principles and to seek to integrate environmental concern into all other areas of science and technology development. There is also a widespread effort to foster new ways to involve the 'public' in the making of science and technology policy. The article is based on results from the project, Public Engagement and Science and Technology Policy Options (PESTO), for which the author served as coordinator.     

Are batteries ready for plug-in hybrid buyers?

The notion persists that battery technology and cost remain as barriers to commercialization of electric-drive passenger vehicles. Within the context of starting a market for plug-in hybrid electric vehicles (PHEVs), we explore two aspects of the purported problem: (1) PHEV performance goals and (2) the abilities of present and near-term battery chemistries to meet the resulting technological requirements. We summarize evidence stating that battery technologies do not meet the requirements that flow from three sets of influential PHEV goals due to inherent trade-offs among power, energy, longevity, cost, and safety. However, we also show that part of this battery problem is that those influential goals are overly ambitious compared to goals derived from consumers’ PHEV designs. We elicited PHEV designs from potential early buyers among U.S. new car buyers; most of those who are interested in a PHEV are interested in less technologically advanced PHEVs than assumed by experts. Using respondents’ PHEV designs, we derive peak power density and energy density requirements and show that current battery chemistries can meet them. By assuming too aggressive PHEV goals, existing policy initiatives, battery research, and vehicle development programs mischaracterize the batteries needed to start commercializing PHEVs. To answer the question whether batteries are ready for PHEVs, we must first answer the question, “whose PHEVs?”
