We study the interactive association of press freedom, access to media and education with a nation's corruption levels. A free press generates unbiased information that greater access to the media helps propagate; and a greater degree of education, in the same context, helps individuals apply that information. This entire process generates a vigilant and corruption‐free economy. It is therefore important to consider these factors in conjunction. 相似文献

We study the effect of parameter uncertainty on the long‐run risk for three asset classes: stocks, bills and bonds. Using a Bayesian vector autoregression with an uninformative prior we find that parameter uncertainty raises the annualized long‐run volatilities of all three asset classes proportionally with the same factor relative to volatilities that are conditional on maximum likelihood parameter estimates. As a result, the horizon effect in optimal asset allocations is much weaker compared to models in which only equity returns are subject to parameter uncertainty. Results are sensitive to alternative informative priors, but generally the term structure of risk for stocks and bonds is relatively flat for investment horizons up to 15 years.

Capitalism and democracy in the 21st Century: from the managed to the entrepreneurial economy* 总被引:2,自引:1,他引:2
This paper explains how and why the developed countries are undergoing a fundamental shift away from a managed economy and
towards an entrepreneurial economy. This shift is shaping the development of western capitalism and has triggered a shift
in government policies away from constraining the freedom of business to contract through regulation, public ownership and
antitrust towards a new set of enabling policies which foster the creation and commercialization of new knowledge. The empirical
evidence from a cross-section of countries over time suggests that those countries that have experienced a greater shift from
the managed to the entrepreneurial economy have had lower levels of unemployment. 相似文献

This paper presents the first value of statistical life (VSL) meta-analysis that empirically estimates correction factors
for ‘out of context’ benefits transfer (BT) purposes. In the field of mortality risk reductions elicited willingness to pay
values in one risk context, say road safety, are frequently applied in other risk contexts like air pollution. However, differences
in risk perception and the population at risk across contexts are likely to result in diverging VSL estimates. In a meta-analysis
of 26 international stated preference studies, a Bayesian model is estimated regressing contingent values for mortality risk
reductions, originating from three different risk contexts, on the characteristics of the risk reduction itself and additional
variables characterizing the underlying studies. A willingness to pay (WTP) premium for mortality risk reductions in the air
pollution and general mortality risk context relative to improving road safety is observed. Evaluated at the mean, road safety
VSL estimates should be multiplied by a factor 1.8 before being applicable in the air pollution context. Moreover, in an illustrative
BT exercise we find limited overlap in the set of context specific predictive VSL distributions. Consequently, ‘out of context’
BT results in a substantial over- or underestimation of the VSL. 相似文献

Increasing deer populations can be controlled through manipulatingharvest limits or season length. While such actions often result in benefitsto hunters, both motorists and the agricultural sector also benefit as alower deer population leads to fewer incidences of harmful human-deerencounters. Traditional recreation demand models are often employed toexamine the welfare implications of changes in daily hunting bag limits.Studies measuring the effects of changes in season length, however, arenoticeably absent from the literature. This study uses a nested randomutility model to examine hunter choice over site and season selection toderive the values of changes in season length. 相似文献

The two‐country Ricardian trade model with discrete goods and uniform transport costs for tradable goods is applied to the decomposition of the real exchange rate into traded and nontraded components. The real exchange rate is driven almost entirely by changes in the productivity differentials in nontraded goods and also explains the Balassa–Samuelson effect of a lower cost of living in poor countries, but extraordinary transport costs for some nontraded goods are necessary to easily explain the Balassa–Samuelson effect. 相似文献

For several decades now, critical public health researchers have highlighted the deleterious effects that pursuing neoliberal policies can have on the ‘causes of the causes’ of poor health and upon growing health inequalities. This paper argues that the conceptual tools of Karl Polanyi can help lend particular insight into this issue. The specific example that this paper focuses upon is the ‘social enterprise’: a form of organisation that combines both social and business objectives. The paper explores, conceptually, whether social enterprises may have the potential to act as one component of a neo-Polanyian countermovement: helping to re-embed the economy back into society, and offering greater recognition for a more comprehensive and socially imbued concept of health. Importantly, this potential is critically examined in the context of neoliberal hegemony, where challenges to the status quo have regularly been met with assimilation, co-option and/or repression. 相似文献

This study tests the temporal stability of preferences, choices and willingness to pay (WTP) values using both discrete choice experiment (DCE) and open-ended (OE) WTP elicitation formats. The same sample is surveyed three times over the course of two years using each time the same choice sets. Choice consistency is positively correlated with choice certainty and choice complexity. The impact of choice complexity fades away in time, most likely as a result of learning and preference refinement. Although the OE WTP values remain stable over a time period of 2 years as in previous stated preference studies, DCE based WTP measures differ significantly, suggesting their use in benefits transfer may be limited. 相似文献

This paper analyzes the existing relationship between ethnic fractionalization, corruption and the growth rate of a country. We provide a simple theoretical model. We show that a nonlinear relationship between fractionalization and corruption exists: corruption is high in homogeneous or very fragmented countries, but low where fractionalization is intermediate. In fact, when ethnic diversity is intermediate, constituencies act as a check and balance device to limit ethnically-based corruption. Consequently, the relationship between fractionalization and growth rate is also non-linear: growth is high in the middle range of ethnic diversity, low in homogeneous or very fragmented countries. 相似文献

Based on a CGE exercise of a subsidy to initiate ethanol production in Mexico, we use Monte Carlo simulations for consumer demand elasticities and ethanol cost estimates. The analysis provides three conclusions: when markets vary smoothly and predictably, Monte Carlo methods can then help to gauge the actual probability that a given program will achieve a desired outcome. Second, secondary markets may display little or no sensitivity to these parameter variations. Finally, a ‘razor’s edge’ outcome with no positive benefits if a critical parameter falls below some critical value, reveals that an economic policy may not be conducive to ‘fine tuning’ by marginal adjustments. 相似文献
