Mancur Olson's institutional sclerosishypothesis may be evident in the effects ofinterest groups on investment in physicalcapital. To test this proposition, we usecross sectional data on 42 countries forwhich information on the number of interestgroups is available to estimate the effectof those groups on the share of GDP thatgoes into physical investment. The resultsindicate that interest groups have adifferent effect on physical investment inOECD and non-OECD countries. In the OECDcountries, we find support for thehypothesis that interest groups harminvestment in physical capital. Indeveloping countries, interest groupseither have no effect on physicalinvestment or they have a slight beneficialimpact.  相似文献

This article tests three hypotheses concerning the policy effects of foreign exchange market liberalization and exchange controls in the three Caribbean Common Market countries of Jamaica, Trinidad & Tobago, and Barbados during the 1990s. It concludes that these cases do not show either monetary or fiscal policy to be particularly effective, when foreign exchange markets are liberalized before a functional bank regulatory system is put in place. These cases also imply that given the challenges posed by financial services globalization, the need for informed judgment by governments regarding the pace and scope of financial sector liberalization will remain critical, particularly within small developing countries.  相似文献

The role of governmental risk aversion in the decision to privatize the production of goods and services has not been examined closely. Using a model of a risk-averse, single-service Niskanen bureaucrat, we determine the conditions under which a bureaucrat will prefer to privatize rather than produce in-house. If the private-sector firm is risk neutral, the result will be a fixed-fee contract with complete insurance. If the private-sector firm is risk averse, the result will be a cost-plus contract with the degree of cost sharing determined by the bureaucrat's share of total risk aversion. In both cases, the bureaucrat's sponsor may affect the likelihood of privatization by manipulating the rewards and penalties imposed on the bureaucrat.  相似文献

Der Beitrag widmet sich dem für Parteispenden ma?geblichen § 4 des Parteiengesetzes mit dem Ziel, die Struktur der Bestimmung zu erl?utern und ihre Schw?chen offen zu legen. Dabei wird der Versuch unternommen, aufzuzeigen, inwieweit der Gesetzgeber eine für die politische Praxis günstige Regelung getroffen hat, die bereits aufgrund ihres Abwendungsbereichs nicht geeignet ist, politische Transparenz zu erzeugen, sondern umfassende Verschleierungsm?glichkeiten bietet und fast schon forciert.  相似文献

Abstract:  Artifacts due to decomposition can be mistaken for antemortem injury leading to an incorrect suspicion of foul play. We describe an instance of postmortem wound dehiscence that mimicked antemortem stab wounds. A man with a history of colon cancer and substance abuse was found dead. There were advanced putrefactive changes and multiple defects of the anterior torso that resembled stab wounds. Subsequent investigation revealed that 11 months earlier, he had a laparoscopic-assisted colon resection that involved surgical incisions corresponding in location and size to the above defects. Putrefactive gases may cause bloating of the body. This distension may cause recent and remote healed incisions to dehisce. Correlation of these "defects" at autopsy with the antemortem clinical history is crucial in determining their etiology.  相似文献

The establishment of offender DNA databases is critical to future crime prevention. Many countries have established databases or are in the process of passing database legislation. With new legislation the number of samples that will be collected could begin to exceed the testing capacity of many labs leading to backlogs.Two bottlenecks in the workflow that can contribute to a backlog of samples are DNA purification and PCR cycling time. The average purification time is approximately 2 h and the average cycling time of current STR kits is approximately 3 h. To address the second problem we investigated alternative DNA enzymes to decrease PCR cycling time. It was necessary to balance the increase in time to result against the need to address factors which can impact interpretation of a DNA profile such as: generation of stutter products, non-template addition, intra-locus balance, accuracy, and species specificity.Initial feasibility studies demonstrate that alternative enzymes can decrease PCR cycling time. The data show that this assay can increase throughput, providing results in less than 2 h. However, decreasing PCR cycling time will have an affect on multiplex STR performance.  相似文献
