Declining labor force participation of older men throughout the 20th century and recent increases in participation have generated substantial interest in understanding the effect of public pensions on retirement. The National Bureau of Economic Research's International Social Security (ISS) Project, a long-term collaboration among researchers in a dozen developed countries, has explored this and related questions. The project employs a harmonized approach to conduct within-country analyses that are combined for meaningful cross-country comparisons. The key lesson is that the choices of policy makers affect the incentive to work at older ages and these incentives have important effects on retirement behavior.

The main goal of the study is to analyze the metric goodness of the Spanish version of the Adult Prosocialness Scale (Caprara, Steca, Zelli, & Capanna, 2005). Analysis of construct and concurrent validity in two similar samples of young adults, a Spanish sample (target of the adaptation) and an Italian sample (source language), revealed the adequacy of the Spanish version of instrument, with adequate fit of the model in the Spanish group, χ2(96) = 405.28, p = .001, RMSEA = .071, CFI = .94, GFI = .93, and the Italian group χ2(97) = 224.5, p = .001, RMSEA = .075, CFI = .91, GFI = .90. The results also replicated the adequacy of the instrument found in the Italian sample, as the configural and metric invariance was verified in both groups. Analyses of benevolent and power values related to prosociality and differences between genders supported the validity of the scale. In short, the present study confirms the adequacy and sensitivity of the instrument to study prosociality in young adults in a Spanish sample.

We design an agent based Monte Carlo model of antibiotics research and development (R&D) to explore the effects of the policy intervention known as Market Entry Reward (MER) on the likelihood that an antibiotic entering pre-clinical development reaches the market. By means of sensitivity analysis we explore the interaction between the MER and four key parameters: projected net revenues, R&D costs, venture capitalists discount rates, and large pharmaceutical organizations' financial thresholds. We show that improving revenues may be more efficient than reducing costs, and thus confirm that this pull-based policy intervention effectively stimulates antibiotics R&D.

Hazard is the potential of something to cause harm; risk is the likelihood of harm occurring. Chemicals regulation is largely focused on minimising risks associated with chemicals — and rightly so. However, in the EU the hazard classification of individual chemicals can impact significantly the regulation of products containing those chemicals, regardless of the actual risks that the products may pose to human health or the environment. This can lead to undesirable consequences, such as restrictions on the use of safe products, substitution towards less safe products, and disincentives to innovate. Such hazard-based regulation tends to be at odds with World Trade Organization rules and has raised significant concern with EU trading partners. This journal is an ideal forum for discussing how the EU can move towards a better and more coordinated legal framework for the regulation of chemicals.

EPA has conducted several ex post assessments of regulatory compliance costs, with the ultimate goal of identifying ways to improve ex ante cost estimation. The work to date has culminated in four case studies that examine five regulations using a common conceptual framework. The standardized framework provides a systematic way to investigate key drivers of compliance costs to see if judgments can be made about why and how ex ante and ex post estimates of costs differ. In addition to describing this conceptual framework, we describe the criteria used to select the rules to be analyzed, summarize the main hypotheses for why ex ante and ex post cost estimates may differ and discuss some of the challenges encountered in conducting these ex post analyses.
