Several indices measuring hunger and progress in achieving hunger eradication have been proposed in the literature. This paper reviews existing hunger indices and critically assesses their quality against a number of desirable properties. Hunger indices are found to be unsatisfactory in a number of ways: they ignore distributional issues; they neglect the occurrence of food and health shocks; and are sometimes based on unreliable data. Anthropometric measurements, stunting in particular, emerge as powerful indicators of hunger and are ideal for addressing a number of policy relevant issues. The paper also introduces a conceptual framework for an index measuring country commitment to fighting hunger. The constitutive elements of this index are illustrated: political will, anti-hunger policies and programmes. Suggestions are made on how a commitment index can be built and what are the data requirements.  相似文献

Retail Leasing: The Determinants of Shopping Center Rents   总被引:4,自引:0,他引:4  
The determinants of lease rentals are of fundamental importance to real estate researchers and practitioners. Retail leases are unique in that they typically have two rental components: a base rent and an "overage" rent equal to a percentage of the tenant's gross sales above some threshold level. In this paper, we develop and test a simple cash flow model of retail lease valuation that predicts that base rents are lower with higher percentage rent rates and are higher with greater threshold levels of sales. Using a sample of shopping center leases, regression analysis indicates that these tradeoffs are observed in the market.  相似文献

Several different procedures for the implementation of the internal rate of return criterion are presented in the literature on investment projects evaluation. Taking the net present worth criterion as a basis for comparison, a survey of some of the suggested procedures and a critique of their theoretical basis are presented. It is showed that, although leading to a proper evaluaticn, they are internally inconsistent in the sense of incorporating modifications that may not really be necessary. To circumvent this possibility, we are going to suggest a conceptual algorithm that should be implemented if we are concerned with the formal application of the internal rate of return criterion.  相似文献

This paper contrasts the socio-cultural systems underpinning employment relations in the West and in the Overseas Chinese case. The analysis centres on the norm of reciprocity which, whilst taken as a universal phenomena, exhibits significant cross-cultural variation. Western employment relations are characterised by a model of impersonal rational economic exchange in which individuals engage in a utility calculus. Chinese employment relations remain more fully embedded in the wider socio-cultural system of which reciprocity is a vital and integral part. Employment relations are sustained by a personalistic tacit moral order. The implications for managing employment relations in changing and multi-cultural situations are discussed. The sustainabilty of the different employment relations systems are also discussed.  相似文献

Coordinated supply chain scheduling   总被引:1,自引:1,他引:0  
A mixed integer programming approach is proposed for a long-term, integrated scheduling of material manufacturing, material supply and product assembly in a customer driven supply chain. The supply chain consists of three distinct stages: manufacturer/supplier of product-specific materials (parts), producer where finished products are assembled according to customer orders and a set of customers who generate final demand for the products. The manufacturing stage consists of identical production lines in parallel and the producer stage is a flexible assembly line. The overall problem is how to coordinate manufacturing and supply of parts and assembly of products such that the total supply chain inventory holding cost and the production line start-up and parts shipping costs are minimized. A monolithic approach, where the manufacturing, supply and assembly schedules are determined simultaneously, is compared with a hierarchical approach. Numerical examples modeled after a real-world integrated scheduling in a customer driven supply chain in the electronics industry are presented and some computational results are reported.  相似文献

This article considers the broader impact of Community Reinvestment Act (CRA) agreements—bank pledges to extend a certain volume of lending to targeted groups and communities—by examining whether they are associated with changes in lending to lower–income and minority communities in the markets where they are initiated. We find the number of newly initiated CRA agreements in a county to be associated with significant increases in CRA, minority and overall conventional mortgage lending in a county over a three–year period. The results are consistent with the view that the increases in lending represent new lending, with some evidence suggesting that the increases in lending are relatively short–lived. Overall, the results are consistent with the notion that lenders view CRA agreements as a form of insurance against the potentially large and unknown costs associated with fair lending violations, poor CRA performance ratings and adverse publicity from CRA–related protests of mergers or other applications. The results are also consistent with the view that the effectiveness of CRA agreements in increasing lending activity is ultimately determined by the persistence and sophistication of community groups in monitoring compliance with CRA agreements.  相似文献

Competition in telecommunications   总被引:1,自引:0,他引:1  
The author examines the impact of competition from both domestic and international perspectives. He provides a critique of the pro-competition argument, although a number of advantages of competition are also outlined. The advantages are discussed in relation to equipment and services. International trends towards competition are then described and the disadvantages of such trends are debated in relation to cross-subsidization, interconnection, the telecommunications manufacturing industry, and the market structure. Finally, competition in the international arena is discussed.  相似文献

One major problem in the administration of farm input subsidies in Africa is the method by which subsidies are granted to farmers: they are effected in such a way that all farmers, irrespective of their economic and financial capability, benefit equally. However, it is argued that because subsidies allocations are usually limited government ought to concentrate only on farmers who are actually in need. Consequently, a graduated type of rebate as against an all embracing subsidy is suggested as a more realistic approach of granting farm input subsidies to farmers in Africa.  相似文献

This is an investigation into the reasons for young people's union membership decisions in the UK. It is carried out by an examination of a survey of London sixteen-year-old school-leavers (1979–80). The data are used in two ways. First, there is a comparative examination of a similar study based on the Bain-Elsheikh propensity-opportunity model. Second, the data are re-examined to identify different and distinct strands of motivation or action, intrinsically and externally determined. These are related to formal theories from different disciplines which are linked together by the establishment of a definition of a trade union as a group, institution and social movement. The theory is extended to develop hypotheses about membership behaviour in general.  相似文献

This article proposes and empirically tests a causal model of user participation and management information system use. Based on a review of available literature, three variables including user understanding, system quality and user acceptance are identified as intervening in the relationship between user participation and system use. Causal orders among these variables are assumed and a causal model is constructed for empirical testing. Task complexity is introduced as a contingent variable affecting the structure of these causal relationships. The data are collected from 134 users of 77 different information systems in 32 Korean business firms. The results of data analysis support the causal model in general, but suggest that causal relationships among the variables are different according to task complexity. Two separate models of user participation and management information system use, based on the empirical results, are presented for further research, one for more complex and the other for less complex systems.  相似文献

Flat rates are a prominent pricing scheme for telecommunications services and are often preferred by consumers although average costs would be lower in an alternative usage-based tariff. Reasons are that flat rates protect against unexpectedly high costs (insurance effect), are more likely to be chosen if actual usage is overestimated (overestimation effect), and prevent any disutility that is associated with the immediate perception of marginal costs (taximeter effect). This study complements the literature on tariff biases by highlighting that a lack of tariff flexibility is a major impediment to choosing a flat rate: empirical support for this flexibility effect is found, while, at the same time, the insurance and overestimation effect that run in favor of flat rates are confirmed. Finally, the managerial implications of the findings for the introduction of the new cost cap tariff are discussed. The hybrid cost cap tariff can combine the flexibility and the insurance property, and may, therefore, exert a cost cap bias on consumers.  相似文献

The paper describes how six large Swedish multinational corporations manage the task of assuring strategic integration between headquarters and foreign subsidiaries. Swedish companies are shown to address the problem in an informal way and by leaving their foreign subsidiaries a great deal of autonomy. However, in many instances the necessary integration is not assured. Cases of strategic conflict between parts of companies are analysed, characteristics of and trends in the environment of multinational corporations are identified, and theoretical considerations are applied. With this discussion as a basis, some suggestions are advanced about how to involve subsidiaries more in strategic decision making.  相似文献

We study an auction where two licenses to operate on a new market are sold and winning bidders finance their bids on the debt market. Higher bids imply higher debts which affects product market competition. When debt induces firms to compete more aggressively, retail prices are lower than in a model without debt, as are auction revenues. When debt induces firms to compete less aggressively, retail prices are higher than in a model without debt, and the effect on auction revenues is ambiguous. Net firm profits are always higher than in a model without debt due to endogenous credit rationing.  相似文献

Practitioners and researchers have carefully explored the causes of new product failures. Studies have been conducted, results analyzed, and recommendations offered. Yet despite these efforts, new product failure rates have not decreased. In fact, they appear to be increasing in some product categories. Are we missing something? Noting that most research on new product failures has focused on a firm's activities in specific projects, William H. Redmond proposes that new product outcomes might also be influenced by macro-level or environmental factors. By focusing on environmental factors rather than a firm's activities in specific projects, we might better understand why competent firms in one industry consistently experience higher failure rates than those of firms that are no more competent, but operate in a different industry. For example, failure rates for new food products are consistently higher than those for new industrial products. With no evidence that product development professionals in industrial firms are simply superior to their counterparts in the food industry, Dr. Redmond suggests that we need to look beyond specific product development projects and consider the effects of the market in which these products are introduced. Encouraged by past successes, many firms in the food manufacturing business seek sales growth through the development and introduction of additional new products. Over time, this creates a market in which customer demand is fragmented into increasingly small niches and distribution channels are flooded with product choices. As a result, the failure of a new product is more likely than it might have been under less crowded conditions. In much the same way that the population of deer on an island is limited by the available food and physical space, food products are apparently faced with the market equivalent of natural selection. In the absence of available market niches and a clear competitive advantage, a new product's chances for success are meager. In a market that is overcrowded by existing products and new product introductions, it becomes increasingly difficult and uneconomical to identify opportunities for meaningful differentiation. On the other hand, industrial products face a much different set of environmental conditions. Compared to the food manufacturing business, relatively few new industrial products are introduced, and those introductions are typically successful. In most cases, the new products are simply replacements for inefficient or obsolete products. In such an environment, failed introductions are probably the result of errors in the product development process.  相似文献

The purpose of this paper is to provide a theory-based explanation for the adaptive variations in a supply manager's role within a global account management (GAM) relationship. The variations in a supply-side manager's role are explained using a combined knowledge-based view and relational contracting theoretical perspective. The demands of the global customer, which constrain the supply managers' role adaptation, present a unique set of challenges to organizations supplying in global accounts. The new managerial competencies, required for effective global account supply management under global customer's constraints, are described. In conclusion, specific managerial actions are recommended for effective global account supply management, which are intended to engender the development of trust and social capital in the global customer-supplier relationship.  相似文献

This paper demonstrates that vertical restraints are profitably imposed by a manufacturer or wholesaler who has some market power and whose product is sold in a monopolistically competitive downstream market. Simple conditions are developed under which a price floor (resale price maintenance) or a price ceiling is profitable, and under which private incentive for a restraint is sufficient for its social desirability. Where demand elasticities are constant, observed vertical price floors are always welfare-improving but profitable price ceilings may decrease welfare. In the special case of the CES-aggregate-surplus specification with competitive conjectures, price ceilings are profitable and welfare-decreasing.  相似文献

Subjective judgements by planners and managers are a major component in the process of strategic planning. If such judgements are faulty, efforts at better strategic plans are likely to be misdirected. This paper discusses those biases which appear common to both managers and planners when they make judgements about risk. Implications of biased judgement are discussed in a planning context. Although we still do not know the best ways to elicit judgements, the paper concludes with a discussion of subjective sensitivity analysis which appears to offer some hope.  相似文献

This paper explores the factors involved in determining the differential performance of firms in bear markets. Bear markets are identified at the industry level by employing the criterion of a 20 percent drop of the industrial value added index over a period of at least 3 years. Twenty-one matched pairs of Dutch firms which have experienced such bear markets (one successful, the other unsuccessful), are analyzed. The dominant finding is that successful firms follow market-oriented strategies, whereas their unsuccessful counterparts are distinguished by their focus on costs. Success, however, is a multifaceted phenomenon. Differences in initial conditions, in other types of strategic measures, in energy levels and in timing are also involved. The findings are related to the literatures on decline, failure, turnaround and transformation.  相似文献

This paper analyzes the choice of a technology portfolio by risk-averse firms. Two technologies with random marginal costs are available to produce a homogeneous good. If the risks that are associated with the technologies are correlated, then the firms might invest in a technology with a negative expected return or, conversely, might not invest in a technology with a positive expected return. If the technology with the lower expected cost is riskier than the other technology, then this “low-cost” technology will be eliminated from the firm’s portfolio if the risks are highly correlated. With imperfect competition, the portfolios of firms are different, and the difference in risk tolerance can explain the full specialization of the industry: The less risk-averse firms use the low-cost technology, and the more risk-averse firms use the less risky, higher-cost technology.  相似文献

Proponents argue that mergers should be encouraged as a legitimate strategy to avert (presumably undesirable) hospital closures. More recently, antitrust activity directed at not-for-profit hospitals has intensified. This study attempts to shed some light on the policy debate by testing whether merger targets are indeed candidates for closure, namely hospitals with persistent losses. Acquisitions of independent not-for-profit hospitals by other hospitals and by multihospital corporations are observed from a national sample for the period 1982–1987. The likelihood of being acquired in during any year within that period is estimated using a discrete-time hazard rate model. We find no evidence to support the notion that hospitals with weak financial indicators are more likely to be acquired. Rather, we find that hospitals with high operating-margins that are located in less regulated markets, and to a certain extent in high-growth markets, are more likely to be acquired. These findings cast doubt on certain predictions found in the theoretical literature, but are in agreement with empirical studies of other industries.  相似文献
