Corlu and Corlu [Quant. Finance, 2014, doi: 10.1080/14697688.2014.942231] provided a novel modelling of exchange rate data for nine currencies using five flexible distributions. They stated that the generalized lambda, skew t and normal inverse Gaussian distributions ‘do a good job’. Here, we reanalyse the data and show that a distribution simpler than all of these fits at least as well as these distributions. We also find that the normal inverse Gaussian distribution provides good fits for only one of the data-sets. 相似文献

Narrowing the gender technology gap in agricultural production has become a critical policy issue in sub‐Saharan Africa. A better understanding of the gender technology gap is essential for policy formulation and programme planning to ensure equity in resource allocation, and household‐level food security in low and middle income countries, such as Ghana. We employ a metafrontier approach to analyse the differences in the efficiency of male and female farmers, recognising the endogeneity of some of the variables in the inefficiency effects model, in particular the credit constraints of the rice farmers under study. Our findings show that while the rice farms themselves are very similar, average yields for male managed farms tend to be significantly higher than female managed farms reflecting higher seeding and fertiliser application rates on male managed farms. However, there is no significant difference between the genders in either land used for rice or total output per farm household. We find some evidence that relative to the metafrontier, male managed farms are less efficient than female managed farms. The results further show gender technology gap amongst the smallholder rice farmers with females’ technology gap ratio being significantly greater than that of males, with females operating on a production frontier closer to the metafrontier. Policies that provide females more access to productive resources and other agricultural services could assist in the generation of relatively higher output. 相似文献

ABSTRACT The strategic importance of managing organizational culture has been a central theme in organizational literature over the past two decades. But relatively little attention has been given to the impact of culture change initiatives on managers. This paper reports on the impact of a programme of culture change on managers at one of Britain's leading grocery retail chains. Based on a series of detailed interviews with managers together with examination of company documents and an understanding of trends in grocery retailing, we explain the purpose and content of change, and document and analyse the reactions of those managers who are expected to change their own cultural orientations as well as persuade their subordinates to change. We conclude that in this case at least changes in managerial behaviour, as with previously documented changes in the behaviour of shopfloor workers, are related more to surveillance, direct control and the threat of sanction than any transformation of managerial values. Indeed, the situation and experiences of managers – one of reduced autonomy, close monitoring and control, and perceived career insecurity – are explained less in relation to ‘organizational culture’, more in relation to organizational (re‐)structuring intended to create a more centralized form of organizational control. 相似文献

This paper analyzes the optimal treatment of tax expenditures. It develops an optimal tax model where individuals derive utility from spending on a “contribution” good such as charitable giving. The contribution good has also a public good effect on all individuals in the economy. The government imposes linear taxes on earnings and on the contribution good so as to maximize welfare. The government may also finance directly the contribution good out of tax revenue. Optimal tax and subsidy rates on earnings and the contribution good are expressed in terms of empirically estimable parameters and the redistributive tastes of the government. The optimal subsidy on the contribution good is increasing in the size of the price elasticity of contributions, the size of the crowding out effect of public contributions on private contributions, and the size of the public good effect of the contribution good. Numerical simulations show that the optimal subsidy on contributions is fairly sensitive to the size of these parameters but that, in most cases, it should be lower than the earnings tax rate. 相似文献

Using an overlapping generations production‐economy model characterized by financial repression, purposeful government expenditures and cost of tax collection, we analyse whether financial repression can be explained by the cost of raising taxes. We show that with public expenditures affecting utility of the agents, modest costs of tax collection tend to result in financial repression being pursued as an optimal policy by the consolidated government. However, when public expenditures are purposeless, the above result only holds for relatively higher costs of tax collection. But, more importantly, costs of tax collection cannot produce a monotonic increase in the reserve requirements. What are critical, in this regard, are the weights the consumer assigns to the public good in the utility function and the size of the government. 相似文献

A quadratic version of the first-difference Okun’s Law model was estimated for Spain (1995.Q1-2012.Q2). An accelerationist version of Okun’s Law was obtained, which allowed us to calculate variable Okun coefficients as well as critical points in the relationship between construction sector growth and the variation in overall unemployment. The optimal economic growth rate was determined to be 7.38 %. By applying principal components, it is demonstrated that this sector led the economic process after 1995. 相似文献

We reexamine the Unemployment Rate (UR) – government expenditure nexus in a panel of 50 State and Local Governments (SLGs) over the period 1977–2006 to provide new pre-recession empirical evidence that helps put the expectations on the effects of the federal relief to SLGs in a broader context. We found that: (1) per capita real public spending (total and capital, assistance and subsidies, wages and salaries, and social insurance categories) was part of a cointegrating relationship with UR and real per capita state personal income. (2) With the exception of social insurance, other spending variables, when statistically significant, actually had a depressing effect on UR. The magnitude of this effect, however, was generally small. UR was most sensitive to increases in wages and salaries. (3) Long-term causality analysis based on panel error-correction coefficients provided consistent evidence of a causal effect from spending to UR, but less consistent evidence of such effect in the opposite direction. Social insurance, however, drove UR. (4) The size of the error-correction coefficients suggested a slow response of UR to deviations from the cointegrating relationship. (5) The marginal effect of spending on UR increased with the amount of the federal grants received. Our results suggest that public spending may not serve as a quick fix in relation to UR. They also seem to favour allocation of the federal funds to wage and salaries and assistance and subsidies, but not to capital and social insurance expenditures to lower UR. 相似文献

Thanks to the access to labeled orders on the CAC 40 index future provided by Euronext, we are able to quantify market participants contributions to the volatility in the diffusive limit. To achieve this result, we leverage the branching properties of Hawkes point processes. We find that fast intermediaries (e.g. market maker type agents) have a smaller footprint on the volatility than slower, directional agents. The branching structure of Hawkes processes allows us to examine also the degree of endogeneity of each agent behavior, and we find that high-frequency traders are more endogenously driven than other types of agents. 相似文献

A new test is proposed for the weak white noise null hypothesis. The test is based on a new automatic selection of the order for a Box–Pierce (1970) test statistic or the test statistic of Hong (1996). The heteroskedasticity and autocorrelation-consistent (HAC) critical values from Lee (2007) are used, allowing for estimation of the error term. The data-driven order selection is tailored to detect a new class of alternatives with autocorrelation coefficients which can be o(n−1/2) provided there are sufficiently many of such coefficients. A simulation experiment illustrates the good statistical properties of the test both under the weak white noise null and the alternative. 相似文献

This paper uses both Data Envelopment Analysis (DEA) and Free Disposal Hull (FDH) models in order to determine different performance levels in a sample of 353 foreign equities operating in the Greek manufacturing sector. Particularly, convex and non-convex models are used alongside with bootstrap techniques in order to determine the effect of foreign ownership on SMEs’ performance. The study illustrates how the recent developments in efficiency analysis and statistical inference can be applied when evaluating performance issues. The analysis among the foreign equities indicates that the levels of foreign ownership have a positive effect on SMEs’ performance. 相似文献
