In this article, we critically review the three most common approaches of assessing chronic food insecurity and undernutrition: (i) the FAO indicator of undernourishment, (ii) household food consumption surveys, and (iii) childhood anthropometrics. There is a striking and worrying degree of inconsistency when one compares available estimates, which is due to methodological and empirical problems associated with all three approaches. Hence, the true extent of food insecurity and undernutrition is unknown. We discuss strengths and weaknesses of each approach and make concrete suggestions for improvement, which also requires additional research. A key component will be the planning and implementation of more comprehensive, standardized, and timely household surveys that cover food consumption and anthropometry, in addition to other socioeconomic and health variables. Such combined survey data will allow much better assessment of the problems’ magnitude, as well as of trends, driving forces, and appropriate policy responses.  相似文献

This paper investigates the relationship between flexible human resource (HR) practices and innovativeness. Testing the research model in a sample of first‐tier automotive suppliers indicates that internal flexibility practices are positively related to innovativeness. Regarding external flexibility, the association depends on the type of contingent employee: negative association for ‘short‐term hires’ and positive association for ‘consulting/contracting firms’. The relationships to innovativeness for practices associated with knowledge transfer are moderated by environmental dynamism, but the non‐knowledge related practices are not. Firms in highly dynamic environments can benefit more from flexible HR practices than firms in less dynamic environments.  相似文献

We use instrumental variable methods to investigate whether the impact of parental smoking habits on their children's smoking decisions is a causal one. We find suggestive evidence of same‐sex role models in two‐parent households: mothers play a more crucial role in determining their daughters’ smoking decisions, whereas fathers’ smoking habits are primarily imitated by their sons. This same‐sex parent–child link is no longer at play for teenagers living in single‐mother households, for whom the influence of their only cohabiting parent turns out to be predominant independently of gender.  相似文献

The purpose of this paper is to describe the design of Global Leadership Life Inventory (GlobeInvent), a 360-degree leadership feedback instrument. This instrument is presently used in executive programmes to help identify the operational mode of individual executives. Proper use of this instrument enables the user to determinate those areas of leadership behaviour where improvement is needed.

Because most studies pay attention only to the surface manifestations of leadership, most leadership feedback instruments, in turn, are not concerned with the psychodynamic processes that underlie leaders' character and behaviour. To address this gap, the GlobeInvent is based on a clinical orientation to the study of leadership. This approach provides a more complete analysis of the ‘inner theatre’ of leaders?–?that is, what makes them tick?–?as well as measuring the dynamic, two-way relationship between leaders and followers.

The first step in designing the instrument was to pinpoint significant themes pertaining to exemplary leadership. To that end, semi-structured interviews with senior executives were held. The leadership dimensions that emerged from that process were then tested on an international sample of senior executives. Analysis of the data from the testing confirmed the existence of twelve robust dimensions with a high reliability and internal consistency.

Because the GlobeInvent is a 360-degree feedback instrument, this article addresses differences between ‘Self’ scores and scores given by others (‘Observers’), gender differences in scoring and the influence of nationality, management experience and age on test results. The implications of using such an instrument as a 360-degree feedback tool are reviewed, and suggestions for future research are offered.  相似文献

Central Bank Independence: An Update of Theory and Evidence   总被引:4,自引:0,他引:4  
This paper reviews recent research on central bank independence (CBI). After we have distinguished between independence and conservativeness, research in which the inflationary bias is endogenised is reviewed. Finally, the various challenges that have been raised against previous empirical findings on CBI are discussed. We conclude that the negative relationship between CBI and inflation is quite robust.  相似文献

This paper reviews the economic literature on the role of fees in patent systems. Two main research questions are usually addressed: the impact of patent fees on the behavior of applicants and the question of optimal fees. Studies in the former group confirm that a range of fees affect the behavior of applicants and suggest that a patent is an inelastic good. Studies in the latter group provide grounds for both low and high application (or pre‐grant) fees and renewal (or post‐grant) fees, depending on the structural context and policy objectives. The paper also presents new stylized facts on patent fees of 30 patent offices worldwide. It is shown that application fees are generally lower than renewal fees, and renewal fees increase more than proportionally with patent age.  相似文献

We defend the precautionary principle against five common charges, namely that it is ill-defined, absolutist, and a value judgement, increases risk-taking, and marginalizes science. We argue, first, that the precautionary principle is, in principle, no more vague or ill-defined than other decision principles and like them it can be made precise through elaboration and practice. Second, the precautionary principle need not be absolutist in the way that has been claimed. A way to avoid this is through combining the precautionary principle with a specification of the degree of scientific evidence required to trigger precaution, and/or with some version of the de minimis rule. Third, the precautionary principle does not lead to increased risk-taking, unless the framing is too narrow, and then the same problem applies to other decision rules as well. Fourth, the precautionary principle is indeed value-based, but only to the same extent as other decision rules. Fifth and last, the precautionary principle is not unscientific other than in the weak sense of not being exclusively based on science. In that sense all decision rules are unscientific.  相似文献

The purpose of this study was to assess additionality and the practice of estimating the cost of equity capital in 70 renewable energy projects in Brazil. Forty projects demonstrated additionality by means of financial analysis. No strong or clear relationships were found between project characteristics and the financial method used to demonstrate additionality. Among projects that used financial analysis, the evaluation often employed the risk-free rate. Failure to add any risk premium to projects of this nature suggests a certain analytical carelessness, perhaps induced by the innovative or experimental nature of these projects.  相似文献

A lack of consensus remains on what should form the theoretical core of the undergraduate intermediate macroeconomic course. In determining how to deal with the Keynesian/classical divide, instructors must decide whether to follow the modern approach of building macroeconomic relationships from micro foundations, or to use the traditional approach based on aggregate models of the macroeconomy. In this article, the authors discuss the advantages and shortcomings of each approach in the context of course objectives. Because there is significant heterogeneity in textbook coverage, the authors summarize some of the approaches taken in current intermediate-level textbooks, which should serve as a useful starting point for new instructors. The authors also discuss how each approach can be extended to analyze the recent recession in the United States.  相似文献

International Monetary Fund (IMF)‐supported programmes catalyse private capital to non‐defaulting countries. We find the IMF to be effective in stimulating private capital flows to middle‐income countries that participate in a Fund programme, but do not restructure their debt. IMF‐supported programmes help non‐defaulting countries to signal their willingness to reform and repay debts, thereby catalysing private capital. This signalling role appears to be more important for Fund catalysis, than the size of IMF lending.  相似文献
