We test for fractional dynamics in US monetary series, their various formulations and components, and velocity series. Using the spectral regression method, we find evidence of a fractional exponent in the differencing process of the monetary series (both simple-sum and Divisia indices), in their components (with the exception of demand deposits, savings deposits, overnight repurchase agreements, and term repurchase agreements), and the monetary base and money multipliers. No evidence of fractional behaviour is found in the velocity series. Granger's (Journal of Econometrics, 25, 1980) aggregation hypothesis is evaluated and implications of the presence of fractional monetary dynamics are drawn. 相似文献
"The aim of this paper is to analyze empirically the causal relationship, if any, between infant mortality and fertility in thirty-five developing countries." The focus is on possible relationships between the infant mortality rate and the fertility rate. "The hypothesis that infant mortality causes fertility is tested. The possibility of a 'reverse causation' is also analyzed. A one-sided distributed lag test as proposed by Granger...is employed." The results are analyzed in light of several versions of the mortality-fertility proposition, including demographic transition theory, choice theory, Ricardian theory, and the modern economic theory of population. 相似文献
Sukuk is a highly appealing alternative instrument of conventional bond in the financial market over the last two decades. To a certain extent, the market players assume sukuk as the same as bond. However, sukuk has its own fundamental asset backed principles, whereas bond is backed by debt. The objective of the study is to examine the Granger‐causality and lead–lag relationship between sukuk and bond by using the data of the Malaysian Government securities return for both conventional and Islamic instruments. The data for every working day of 7 years covering the period from January 31, 2007 to December 31, 2013 were collected from Bloomberg database. The yield returns of both securities have been plotted for each six months of a year. This study applied both Granger‐causality and dynamic co‐movement techniques such as, continuous wavelet transforms (CWT) coherence for analyzing the temporal evolution of the frequency content of both securities by decomposing each period into different time scales. The empirical findings of the paper reveal that with a bit of exception, there is a causal relationship between sukuk securities and conventional bonds for a given period of time. For robustness, this study applied the wavelet coherence approach and found that bond is led by sukuk in the long term investment horizon rather than in the short term. Our findings relating to the lead‐lag relationship between sukuk and bonds have important implications in terms of policy regulations and investment management. Future research and market practices could reinvestigate the differences between these two securities across different markets and types. 相似文献
This paper designs an acreage response model under the acreage allotment farm program incorporation a policy-inducing variable.
The single-equation regression model for each rice-producing state is estimated by the ordinary least squares mulitiple regression
procedure. The estimated parameter shows a significant direct relationship between the rice acreage planted and plicy-inducing
price in all the rice-growing states. The estimated short-run elasticities for Arkansas, California, Louisiana, Mississippi,
and Texas were 0.72, 0.59, 0.67, 0.66, and 0.81 respectively. The heterogeneity in the magnitude of the elasticities during
the acreate allotment period suggests considering a rice program formulation in response to each state's variability in physical
restraints, availability of irrigation water, average yields, and return over cost, thereby providing risk management incentives
to rice growers to respond positively to the farm program. 相似文献
This paper reports the results of a study undertaken to assess the economics of wheat production in Bangladesh. In financial terms, boro (winter) rice is the most profitable crop in irrigated zones, but wheat often generates the highest returns in non-irrigated zones and in areas that are unsuitable for boro rice production. When inputs and outputs are assigned economic prices, wheat production represents the most efficient use of domestic resources in most non-irrigated zones and in one irrigated zone. Should present trends continue and Bangladesh become self-sufficient in rice, wheat production would become even more attractive. In view of these findings, recent calls to scale back wheat promotion activities and curtail investment in wheat research must be questioned. 相似文献
This research examines consumers’ processing of Facts-up-front food labels as implemented by the Grocery Manufacturers Association (GMA). Facts-up-front labels include both positive (virtues) and negative (vices) nutritional icons. The processing and relative efficacy of Facts-up-front labels are compared to the original FDA proposal of front-of-pack labels which only included vices. The results suggest heuristic processing of these labels, whereby consumers consider the nutritional icons on the front-of-pack labels similar to affective stimuli. The addition of virtues alongside vices on the label has a compensatory effect, i.e., the food item is evaluated as healthier when there are both virtues and vices on the label compared to when there are only vices. Such heuristic processing of Facts-up-front labels that allows nutritional virtues to compensate for nutritional vices has the potential for consumers evaluating harmful foods as relatively “healthy” thus compromising consumer well-being. These findings illustrate the importance of empirically testing changes to nutritional labels before large scale implementation. Since consumers process front-of-pack labels heuristically and not cognitively, it is not surprising that nutritional literacy does not moderate the effects of label design on healthiness evaluations. Furthermore, the order of the negative and positive information on Facts-up-front labels also has no effect.
Based on my study of the Rhodes Must Fall movement, I develop a rejectionist perspective by identifying the understanding and mobilization of epistemic disobedience as the core premise of such a perspective. Embedded in this contextual perspective, epistemic disobedience refers to the decolonization of the self and a fight against colonial legacies. I argue that, rather than viewing a rejectionist perspective as a threat, it should be integrated into the moral learning of contemporary institutions and businesses. This approach is important in ensuring colonial legacies and biases do not create further racism or unequal situations for marginalized groups. The implication for critical management studies is that scholars from this camp should be more sensitive to issues of black consciousness and implement an authentic pragmatic ideal to promote black culture and historiographies in universities and curricula. It also highlights a need for the field of business ethics to apply more sensitive theory of marginalized stakeholders in order to prevent any escalation of violence by multinational corporations in the name of shareholder value creation and profit-maximization.
We study the contribution of natural resource intensity to long-term development along different dimensions: per-capita income, institutional quality, and education. We allow natural resources to affect these dimensions differently in different regions of the world. The evidence suggests that natural resources are generally a positive driver of development, but in Sub-Saharan Africa (SSA) their contribution is almost negligible, if not even negative. We explain these cross-regional differences with the fact that in SSA more than anywhere else large resource endowments are combined with a particularly bad disease environment. Some historical evidence and formal econometric results support this hypothesis. 相似文献
Does financial market development enhance the effectiveness of R&D investment in an economy? To address this question, we apply three distinct approaches including (i) ordinary least square method, (ii) cross-country instrumental variable regression approach, and (iii) panel regression method. By using a dataset of both developed and emerging countries, we find that financial market development significantly contributes to the effectiveness of total R&D investment. This finding remains robust across different model specifications and individual estimation methods. Our finding provides an important guidance to policy makers in implementing a sound financial environment that can facilitate the total contribution of R&D investment. 相似文献
