We examine the relative importance of the growth of physical and human capital and the growth of total factor productivity (TFP) using newly organized data on 145 countries that spans more than 100 years for 23 of these countries. For all countries, only 14% of average output growth per worker is associated with TFP growth. We use priors from theories to construct estimates of the relative importance of the variances of aggregate input growth and TFP growth across countries. Much of the importance of the variance of TFP growth across countries is associated with negative TFP growth. (JEL O47 , O50 , O57 , O30 , N10 )  相似文献

The U.S. public's current knowledge about politics is comparedwith levels of knowlege in the 1940s and 1950s. Fourteen questionsasked by Gallup on various surveys from 1945 to 1957 were includedon a larger survey of political knowledge conducted by telephonein 1989 with a randomly selected sample of 610 adult U.S. residents.On 8 of the 14 items, the percentage answering correctly in1989 was higher than in the earlier surveys (by 4–15 points).One item showed an increase of 1 percent, two were down 1 percent,and three others declined by 5 percent, 9 percent, and 10 percent.When level of education is controlled, however, levels of knowledgeappear to have declined for most of the items. A reanalysisof some of the original Gallup data is used to estimate theeffectiveness of schools in transmitting political informationin 1989 compared with the earlier years.  相似文献

How does government regulation influence the structure of industries? In the coal mining industry increased sfnety can be provided with personal protection devices or with engineering controls; but the type of sfnety standard imposed is important because larger producers have a comparative advantage complying with engineering controls. Time series evidence indicates that the 1969 Coal Mine Health and Sfnety Act, by imposing engineering controls, drove out smaller, less sfne mines, thereby shifting production toward larger mines.  相似文献

Elements of the legal test for obscenity of sexually explicitmaterial indicted in a criminal case are examined. A cross-sectionof residents of Mecklenburg County (Charlotte, NC) were randomlyassigned to view either one of the sexually explicit films andthe sexually explicit magazine charged in the criminal case,or a control film. Before and after the viewing, residents judgedthe materials' appeal to a prurient interest (a shameful, morbid,unhealthy interest in sex) and patent offen siveness (communitytolerance for such material). The results indicated that therespondents felt that the films and magazine did not appealto a shameful, morbid, or unhealthy interest in sex, nor didthey perceive these materials as going beyond the level of toleranceregarding depictions of sexual conduct for the average adultin that community. A lower percentage of subjects thought thecommunity tolerated the materials they had just viewed thanwhen they were asked to report on what they personally tolerated.Fewer people felt the films appealed to a shameful, morbid,or unhealthy interest in sex after they had an opportunity tosee them than before viewing. The advantages of providing jurorsin obscenity cases with information about community standardsbased on summations of personal tolerance for materials actuallycharged in these cases, rather than hypothetical judgments aboutthe community and obscenity, is discussed.  相似文献

The role of television in the increased candidate orientednessof voters in U.S. presidential elections was examined usingdata from eight National Election Studies conducted by the SurveyResearch Center at The University of Michigan. The importanceof candidate personal qualities and traits was estimated usingvoter responses to open-ended questions about the candidates.Candidate personal qualities became more important for televisiondependent voters during the 1960s, and in each post-1964 electionwere less important for voters who relied on newspapers thanfor those who relied on television. The differences did notappear to be a function of the higher level of education ofnewspaper readers.  相似文献
