Recent data on the accumulation patterns of public debt across OECD countries suggests a synthesis is possible between the theoretical and empirical approaches to public debt and also between the traditional and more recent political economy explanations of public debt accumulation. The inductive approach of recent political economy explanations is combined with the intertemporal constraints highlighted in the Ricardian–Barro theory to present a reinterpretation of cross-country debt accumulations patterns. Like the elephant in the blind men and the elephant fable, the conclusion is glaringly obvious. Formal and informal budgetary constraints matter.

This paper examines the influence of government ideology, political institutions and globalization on the choice of exchange rate regime via panel multinomial logit approach using annual data over the period of 1974-2004 in a panel of 180 countries: 26 developed and 154 developing.We provide evidence that government ideology, political institutions and globalization are important determinants of the choice of exchange rate regime. In particular, we find that left-wing governments, democratic institutions, central bank independence and financial development increase the likelihood of choosing a flexible regime, whereas more globalized countries have a higher probability of implementing a fixed regime. More importantly, we find that political economy factors have different effects on the choice of exchange rate regime in developed and developing countries. All our results are robust to panel ordered probit model. 相似文献

文章以蛭石、粉煤灰、沸石为吸附材料,初步研究了它们对Cr6+离子的吸附性能。实验表明,3种吸附剂对Cr6+离子的吸附都受到吸附剂量、溶液pH和搅拌时间等吸附条件的影响。经过对照实验,表明蛭石对Cr6+离子的吸附效果较之粉煤灰和沸石要好,并且在如下吸附工艺条件下:pH 5.5、搅拌时间30min、浓度为10mg/L的Cr6+模拟废水中,蛭石用量为0.1 g/ml最佳,此时最大去除率为70.11%。 相似文献

This paper aims to study the influence of nonlinear pollution accumulation on economic growth by incorporating the nonlinear pollution accumulation into an OLG model. It is shown that the nonlinearity can yield very complex dynamics, including the flip bifurcation resulting in sustained fluctuations in economy. This indicates that the nonlinear pollution accumulation can be a source of intergenerational inequity. To stabilize the complex motion and thus to control the fluctuations, a bifurcation control method from control theory is proposed. The welfare analysis shows the sustainable development criterion can be met in the controlled system but not in the original system. 相似文献

McIntosh and Munk claim that the class schema developed by Erikson and Goldthorpe lacks validity and should not be taken as a basis for studies of intergenerational social mobility. Their paper is founded on a serious misconception of why the schema is in fact used by sociologists in mobility research and, for this reason, their test of its validity is essentially misdirected. In addition, the test itself is not carried out in an appropriate way nor, it would seem, with data of adequate quality. 相似文献

David Hume opposes banks and favors hoarding. The only bank he reluctantly approves of is a public, 100% reserve bank. Other banks increase money supply and prices, hindering exports and economic growth. For Hume, a 100% reserve public bank would lead to “the destruction of paper‐credit” ([1752] 1985, p. 285), fostering economic growth instead by preventing inflation. Additionally, a 100% reserve bank hoards a large quantity of gold and silver, which is available in case of national emergency. 相似文献

This paper analyses a previously unused source of data – the All Media and Product Survey (AMPS) – to arrive at alternative estimates of the post‐transition poverty path. The motivations for using this non‐official data source are twofold: concern over the comparability of the existing official post‐transition datasets – the Income and Expenditure Survey (IES) and Population Census – and a desire to extend analysis of poverty trends beyond 2001. While official data sources are generally preferred for purposes of poverty analysis, the IES and Census collect data at long (5 or 10 year) intervals, and additional years pass before these datasets become available to the public. In some cases there is also concern about data comparability between surveys. The expenditure data contained in the General Household Survey are available annually, although data are captured in a small number of categories that are not very conducive to analysis at the lower end of the income distribution. Analysis on AMPS data confirms the large decline in poverty implied by an increase of R18 billion (in 2000 Rand) in social grant payments between 2000 and 2004. The direction of this trend is consistent with recent research findings based on more frequently analysed data sources, including the work done by Agüero, Carter and May (2005), Seekings (2006 ) and Meth (2006 ). 相似文献

In this paper, I revisit the monopolistic screening problem with two types assuming that consumers are boundedly rational. Bounded rationality implies that the revelation principle does not apply and the choice of the selling mechanism entails a loss of generality. I show that if the monopolist restricts attention to the mechanisms that offer menus of two choices, the profits are lower than in the case of fully rational consumers by the term of order ln λ/λ, where λ is the degree of rationality of the consumers. The monopolist, however, can approximate the profits earned when consumers are fully rational by using a more elaborate message game. 相似文献
