Reconsidering the principal components of central bank independence: The more the merrier?

We use principal component analysis to reassess the link between different attributes of central bank independence and inflation performance. We suggest that coding problems may account for the fact that almost none of the attributes included in the Cukierman index has a systematic, plausible relationship with inflation. The multi-faceted Cukierman index also seems to be out-performed by a much narrower index focusing solely on policy independence. These findings point to the importance of using public choice analysis to isolate the real problem here: namely, finding specific central bank structures that effectively insulate central bankers from political pressures.     

Do financial incentives help low‐performing schools attract and keep academically talented teachers? Evidence from California

This study capitalizes on a natural experiment that occurred in California between 2000 and 2002. In those years, the state offered a competitively allocated $20,000 incentive called the Governor's Teaching Fellowship (GTF) aimed at attracting academically talented, novice teachers to low‐performing schools and retaining them in those schools for at least four years. Taking advantage of data on the career histories of 27,106 individuals who pursued California teaching licenses between 1998 and 2003, we use an instrumental variable strategy to estimate the unbiased impact of the GTF on the decisions of recipients to begin working in low‐performing schools within 2 years after licensure program enrollment. We estimate that GTF recipients would have been less likely to teach in low‐performing schools than observably similar counterparts had the GTF not existed, but that acquiring a GTF increased their probability of doing so by 28 percentage points. Examining retention patterns, we find that 75 percent of both GTF recipients and nonrecipients who began working in low‐performing schools remained in such schools for at least four years. © 2010 by the Association for Public Policy Analysis and Management.     

Results of the 2018 Rapid DNA Maturity Assessment

Three commercially available integrated rapid DNA instruments were tested as a part of a rapid DNA maturity assessment in July of 2018. The assessment was conducted with sets of blinded single-source reference samples provided to participants for testing on the individual rapid platforms within their laboratories. The data were returned to the National Institute of Standards and Technology (NIST) for review and analysis. Both FBI-defined automated review (Rapid DNA Analysis) and manual review (Modified Rapid DNA Analysis) of the datasets were conducted to assess the success of genotyping the 20 Combined DNA Index System (CODIS) core STR loci and full profiles generated by the instruments. Genotype results from the multiple platforms, participating laboratories, and STR typing chemistries were combined into a single analysis. The Rapid DNA Analysis resulted in a success rate of 80% for full profiles (85% for the 20 CODIS core loci) with automated analysis. Modified Rapid DNA Analysis resulted in a success rate of 90% for both the CODIS 20 core loci and full profiles (all attempted loci per chemistry). An analysis of the peak height ratios demonstrated that 95% of all heterozygous alleles were above 59% heterozygote balance. For base-pair sizing precision, the precision was below the standard 0.5 bp deviation for both the ANDE 6C System and the RapidHIT 200.     

Cornwall's Devolution Deal: Towards a More Sustainable Governance?

This article considers the devolution deal signed by Cornwall and the Isles of Scilly in the summer of 2015. It asks if the deal constitutes a more sustainable approach to governance, concluding that while there are some factors that help to enhance sustainability, other areas urgently require more attention. These claims are made through an analysis of a model of sustainability which emphasises the importance of networks and feedback loops envisaging civil society as an adaptive organism. This helps to show that although power is significantly dispersed in some aspects of the ‘Cornwall Deal’, this latter does little to alter the highly centralised nature of governance across England, or provide spaces where local actors can feed back into central policy.     

How important are the cognitive skills of teenagers in predicting subsequent earnings?

How important are teenagers' cognitive skills in predicting subsequent labor market success? Do cognitive skills pay off in the labor market only for students who go to college? Does college benefit only students who enter with strong basic skills? These questions are often parts of current policy debates about how to improve the earnings prospects for young Americans. This paper addresses these questions using two longitudinal data sets with earnings information from the mid‐1980s and early 1990s. It shows that the same evidence can be used to support the claim that cognitive skills are important determinants of subsequent earnings, and that the effect of cognitive skills is modest. It also shows that while some evidence indicates that college pays off more for students who enter with strong cognitive skills than for students who enter with weaker skills, the bulk of the evidence does not support this conclusion. © 2000 by the Association for Public Policy Analysis and Management.
