Cubitt  Robin P. 《Public Choice》1997,93(1-2):165-178
Economics Research Centre, School of Economic and Social Studies, University of East Anglia, Norwich NR4 7TJ, U.K. The paper investigates the claim of Gylfason and Lindbeck (Public Choice, 1994) that a stagflationary bias arises from the interaction between monetary policymaking and wagesetting if, among other things, the government and unions share a concern for inflation. It uses a game theoretic model of this interaction, in which the government plays an economy-wide union. Though simple, this nests several other models as special cases. In that corresponding to Gylfason and Lindbeck's model, the factors which they identify are shown to be sufficient for stagflationary bias, in a specified sense. However, for the union to care about inflation is not a necessary condition. The main result of the paper concerns the more general model. It establishes a set of necessary and sufficient conditions for stagflationary bias, as previously defined. These conditions do not include a shared concern for inflation. The paper comments briefly on the significance of this result for stagflation and economic modelling.  相似文献

A minisatellite probe, MZ 1.3, detecting hypervariable fragment patterns was isolated from a human genomic library. A repetitive sequence of 27 bp length was identified which is contained in the probe approx. 40 times. The MZ 1.3 repeat shows variable homology of 53-73% to the repetitive sequence of the protein III gene of the bacteriophage M13 genome. Polymorphic restriction fragment patterns were found with MZ 1.3 using the enzymes Hinf I, BstN I, Hae III, Mbo I, PstI/Pvu II, and Rsa I. An average of 18 polymorphic fragments was observed using Hinf I as enzyme. The band sharing frequency after Hinf I digestion among unrelated individuals was determined to be 23.8 +/- 7.2%. An example for the application of MZ 1.3 to paternity testing in an incest case is given. The probe can be used with radioactive or non-radioactive detection systems. An approach is presented to compare polymorphic fragment patterns from individuals obtained by independent gel runs on the basis of relative band positions (RBP) and calculated in a computerized analysis.  相似文献

Although law enforcement agencies across the nation have assumed part of the responsibility in the fight against terrorism, significant confusion exists as to the role of local law enforcement. While some agencies have taken steps towards terrorism prevention, little data has been collected on which agencies have taken the greatest steps, how those agencies have changed, and how other agencies should direct their activity. This case study of law enforcement census data from a single state considered variations in terrorism preparedness and predictors of preparedness. Agency size, presence of funding, and other variables significantly predict levels of terrorism preparedness. Important policy implications such as the distribution of funding and which agencies should be working towards terrorism preparedness are discussed.  相似文献

This study probes the interconnections among distrust of government, the historical context, and public support for the death penalty in the United States with survey data for area-identified samples of white and black respondents. Multilevel statistical analyses indicate contrary effects of government distrust on support for the death penalty for blacks and whites, fostering death penalty support among whites and diminishing it among blacks. In addition, we find that the presence of a "vigilante tradition," as indicated by a history of lynching, promotes death penalty support among whites but not blacks. Finally, contrary to Zimring's argument in The Contradictions of Capital Punishment , we find no evidence that vigilantism moderates the influence of government distrust on support for the death penalty, for either whites or blacks. Our analyses highlight the continuing influence of historical context as well as contemporary conditions in the formation of public attitudes toward criminal punishment, and they underscore the importance of attending to racial differences in the analysis of punitive attitudes.  相似文献
