Academic discussions on the relationship between regime type and economic growth of developing countries have been drawn to three linkages, the contribution of a certain type of political authoritarianism to rapid industrial transformation, the trend towards democracy after a long period of sustained economic development, and possible negative economic consequences of democratization itself. There are theoretical reasons to support the first two assertions, but the third proposition is less tenable. The case of Korea shows that democratic changes have resulted in higher consumption, have induced inflationary policy, and have led to wage increases in excess of productivity gains. However, these might well be transitional rather than steady-state phenomena. Political learning can prevent young democracies from becoming captives to distributional coalitions. 相似文献

In this paper, we have provided some support for several hypotheses about the determinants of which governors get reelected. The benefit from being a member of a particular party varies from state to state and from year to year. Personal characteristics such as age are also important. The logits give some support to the importance of coalition formation; reelection is easier in states with low voter turnout and in farm states. The paper is most concerned with the connection between the economic performance and the electoral success of incumbent candidates for governor, and we find support for a model of electoral acountability, in which governors are powerful in state governments and state governments have the ability to differentially tax fixed factors relative to neighboring states.This paper raises some important issues regarding the measurement of variables in political economy, which have wide applicability to other studies in the economics of politics. Peltzman (1988) finds that the difference between the growth rate in state personal income and the national growth rate over a one to four year period prior to the election does not affect gubernatorial electoral outcomes. Concurrently, we find that the current year's growth rate in state personal income and its difference from the national growth rate are not significantly related to electoral success but that the average deviation from predicted state personal income during the governor's tenure in office is significantly related to the odds of getting reelected. That is, the data reject simplistic views of voter behavior and support a sophisticated model of voter behavior. Similarly, Peltzman (1988) has greater success using more sophisticated, cumulative measures of national economic performance. 相似文献

Abstract: Within the framework of the ENFSI Expert Working Group "Firearms" a proficiency test on the detection and identification of GSR by energy-dispersive scanning electron microanalysis (SEM/EDX) is carried out in a 2 years term. The latest test was performed in 2005/2006 and was denoted as GSR2005 . Seventy-five laboratories from 28 countries participated in this proficiency test and submitted in total 83 independent data-sets. The participating laboratories were requested to determine the total number of PbSbBa containing particles on a synthetic test sample following their own laboratory specific methods of automated GSR particle search and detection by SEM/EDX. Furthermore size and position of the detected particles had to be reported by the laboratories and were evaluated statistically. The results were compiled by means of z -scores according to the IUPAC and EURACHEM guidelines—assessing individual laboratory achievements (inter-laboratory) as well as intra-laboratory performance—and were compared to the results of the previous proficiency test run GSR2003 ( 1 ). The comparison shows that there is a noticeable improvement in the method's detection capability. 相似文献
