This paper explores the complex web of accountability relationships between New Zealand’s tertiary education institutions (TEIs) and the different forums with which they interact. A brief review of the extensive literature on accountability suggests that previous approaches to this topic have largely adopted the perspective of those forums to which accountability is provided. However, the alternative perspectives of those giving an account provide a more insightful understanding of accountability practices.  相似文献

Whereas retailers are some of the biggest buyers that have some of the highest percentages of external spend as a share of revenue, they are not typically included in strategic sourcing research. Strategic sourcing research originated with a focus on supplies for manufacturing. But the strategic sourcing of merchandise by retailers is not as commonly studied. Merchandise sourcing is often approached very differently from manufacturing sourcing and often different teams of buyers with different roles and responsibilities are involved. Leveraging author industry experience and interviews with strategic sourcing executives in manufacturing and merchandise sourcing this notes and debate paper compares strategic sourcing across these domains and identifies fruitful research opportunities for developing a more comprehensive supply chain approach to strategic sourcing research.  相似文献

The substantial investment in models of international food markets prior to and during the Uruguay Round of international trade negotiations has been a mixed blessing so far as the prospects for reform are concerned. At worst, results from these models have misled the negotiations because they have most often ignored a primary concern lending domestic political support to food market interventions, namely the avoidance of risks borne of dependence on international markets. In this paper the reasons for market insulating policies are reviewed and their links with protection elucidated. Some errors that have stemmed from the application of 'standard' but inappropriate models are noted. Finally, the implications of extending the standard method to include dynamic behaviour and market insulating policies are examined.  相似文献

The hybrid nature of convertible bonds continues to interest corporate financial managers, investors, and economists. While much theoretical and empirical research examines an issuer's choice between using straight debt and equity, little research evaluates how an issuer chooses among debt, equity, and convertible bonds. This study extends Marsh's [ 13 ] research on the differences between debt and equity issuers in the United Kingdom by examining U.S. industrial firms that issue debt, equity, or convertible bonds. It also illustrates how various distinguishing features influence the probability that each security will be issued.  相似文献

This paper describes our approach to the problem of automated knowledge acquisition from large databases of examples using an information-theoretic approach. Our previous research has resulted in practical algorithms (ITRULE) for the automatic induction of rules from large example databases. Utilizing these algorithms, the raw data can be transformed into a set of human readable IF THEN rules, thus giving insight into the knowledge hidden within the data. These rules can then be automatically loaded into an expert system shell. Alternatively, they can be used to build a new type of parallel inference system—a rule-based neural network. This process enables a prototype expert system to be automatically generated and up and running in a matter of minutes, compared with months using a manual knowledge-acquisition approach. The resulting expert system can then be used as a sophisticated search and analysis tool to query the original database capable of reasoning with uncertain and incomplete data.  相似文献

Uncertainty concerning the ultimate outcome of tender offers may affect the measurement of changes in shareholder wealth. The uncertainty regarding the outcome of tender offers is measured by estimating the probability of acceptance of tender offers during the period when the tender offers are outstanding. The estimated probability of acceptance of tender offers implies that the amount of uncertainty prior to knowledge of the ultimate outcome is substantial and affects the measurement of expected equity gains. The uncertainty-adjusted measure of the change in shareholder wealth indicates that previous studies may have underestimated the gains expected to result from tender offers.  相似文献

Despite the modern origins of endogenous growth theory, we argue that the ‘Idea for a Universal History with a Cosmopolitan Aim’ written by Immanuel Kant in 1784 provides an early and coherent example of such a theory. Kant's endogenous growth mechanism is driven by the inherent rivalry that exists between agents which increases effort and strengthens the accumulation of knowledge, which in turn is carried through generations. In an exercise in ‘rational reconstruction’, we present a mathematical model of Kant's mechanism. We use the model to contribute to the contemporary policy debate as to whether ‘keeping up with the Joneses’ leads to excessive effort.  相似文献

Abstract The elasticity of substitution between capital and labor and, in turn, the direction of technical change are critical parameters in many fields of economics. Until recently, though, the application of production functions with specifically non‐unitary substitution elasticities (i.e., non‐Cobb–Douglas) was hampered by empirical and theoretical uncertainties. As recently revealed, ‘normalization’ of production‐technology systems holds out the promise of resolving many of those uncertainties. We survey and assess the intrinsic links between production (as conceptualized in a production function), factor substitution (as made most explicit in Constant Elasticity of Substitution functions) and normalization (defined by the fixing of baseline values for relevant variables). First, we recall how the normalized Constant Elasticity of Substitution function came into existence and what normalization implies for its formal properties. Then we deal with the key role of normalization in recent advances in the theory of business cycles and of economic growth. Next, we discuss the benefits normalization brings for empirical estimation and empirical growth research. Finally, we identify promising areas of future research.  相似文献

In 1996 the UK government announced a National Cycle Strategy (NCS) which included a model local cycle strategy. This paper reports on the findings of an ongoing research project, which seeks to evaluate the extent to which recently published local cycle strategies reflect best practice as enshrined in the model guidance. The results suggest that the level of take up of the model strategy is highly variable and ranges from authorities which adopt the model in its entirety to those that effectively ignore it. If government targets for increasing cycle use are to be achieved then it will be necessary for more local authorities to develop robust plans which are consistent with the NCS.  相似文献

An internal solution to an optimal control problem involving conjunctive‐use of surface and groundwater may be inapplicable if water is not sufficiently fungible across space and time. We provide a more general solution and apply it to the problem of allocating a limited amount of water from the Ko‘olau mountains to two Oahu water districts separated by those mountains. The solution involves initially allocating all of the mountain water to the district supplied by groundwater but eventually allocating all of the water to the district supplied by surface water. The conditions for an internal solution hold only in the intervening years when some mountain water is allocated to each district.  相似文献
