The comparative performance of the iterative instrumental variables estimator using structural and predictive criteria

The purpose of this paper is to give experimental evidence on the small-sample properties of the iterative instrumental variables estimator originally proposed byLyttkens [1970], relative to the more conventional methods including ordinary least squares, limited information single equation maximum likelihood and three stage least squares.     

So What Do Parents Want and Expect from a Technology Education Programme? – An Exploration

Everyone seems to have a view on how and what should be taught in our schools and Technology Education is no exception. In New Zealand, as in the United Kingdom, recent legislation has encouraged parents to take a more active role and to voice their opinions (Banks 1994). Satchwell and Dugger (1996) observe that in the current context of educational reform, parents are questioning what students should be expected to know and be able to do. So what do parents want for their children? This investigation briefly documents a new partnership between a College of Education and a primary school in New Zealand. Parents were questioned over the course of the first year of this new partnership, in order to determine their expectations from the Technology programme.     

On the Assessment of Default Risk in Commercial Mortgage Lending

This paper takes an initial step toward the development of an empirically-based model of default risk assessment in the commercial mortgage market. A review of existing empirical studies of residential mortgage and commercial loan default provides evidence for appropriate model specification and estimation. A simple default risk model for commercial mortgages is then developed based upon the generalized default risk models of Jackson and Kaserman [1980] and Vandell [1981]. The model is then examined for its ability to successfully handle a variety of situations and used to test the validity of traditional ratio analysis "rules-of-thumb" employed in commercial lending. Ratio tests are found generally to be inconsistent with an objective of constraining default risk below some maximum. Finally, a modified ratio analysis consistent with the model and with a constrained default risk strategy is introduced.     

A process (re)turn?: Path dependencies,institutions and performance management in Swedish central government

Recent central government reforms have signalled a transition away from output-based governance and control to a more citizen-orientated and outcome-focused performance management ethos. Prior research suggests that this may give rise to institutional inconsistencies related to conflicting performance management logics. In this paper, we argue that rather than resulting in growing pre-occupation with outcomes and effectiveness, the emerging reform agenda may somewhat paradoxically reinforce managerial concerns with the operating processes underpinning public service delivery. Drawing on policy studies and management accounting research informed by new institutional sociology, we theorise these developments by invoking the notion of path dependency. We provide an empirical illustration based on field work in Swedish central government and adopt a multi-level approach in examining the evolution of performance management practices. While evidence of strongly constraining path dependencies is found at the overall policy level a case study in the Swedish Tax Agency shows that these may also embody an element of flexibility such that the meaning of inconsistent performance management logics is re-constructed over time. This illustrates how individual government agencies may link outcomes to operating process concerns and manage implementation problems related to conflicting and uncoordinated reform initiatives.     

Defining and classifying ecosystem services for decision making

The concept of ecosystems services has become an important model for linking the functioning of ecosystems to human welfare. Understanding this link is critical for a wide-range of decision-making contexts. While there have been several attempts to come up with a classification scheme for ecosystem services, there has not been an agreed upon, meaningful and consistent definition for ecosystem services. In this paper we offer a definition of ecosystem services that is likely to be operational for ecosystem service research and several classification schemes. We argue that any attempt at classifying ecosystem services should be based on both the characteristics of the ecosystems of interest and a decision context for which the concept of ecosystem services is being mobilized. Because of this there is not one classification scheme that will be adequate for the many contexts in which ecosystem service research may be utilized. We discuss several examples of how classification schemes will be a function of both ecosystem and ecosystem service characteristics and the decision-making context.     

Weak complementarity and production

This paper describes how weak complementarity, a common assumption to characterize consumer preferences for recovering measures of willingness to pay for nonmarketed environmental resources, can be used to evaluate the effects of pollution that may affect profits or costs. In such cases, pollution serves as an externality imposed by third parties on production activities.     

Comparing schools in the U.K. and New Zealand: individualizing and socializing accountabilities and some implications for management control

This paper contrasts educational reforms in New Zealand and the U.K. exploring the role of accountability in processes of management control. The paper focuses on the use of performance measurement in schools. Performance evaluation in the U.K. is, arguably, individualized, in New Zealand an organizational focus is retained The paper will seek to provide an account of the way that individuals have been called to account for their performance (Townley, 1996). Roberts' (1996) discussion of individualizing and socializing accountability is central because of its key claim that some forms of organizational accountability provide a separation of the strategic and moral consequences of action. This is seen as potentially damaging as it may free instrumental action from any form of ethical constraint, equally it may undermine any potential for collective action. In exploring this dimension we will examine the technologies of both financial accounting and management accounting which promote particular approaches to performance evaluation, accountability and control. Our argument raises questions as to the relevance of management accounting as a tool of control and whilst recognizing that financial accounting is also limited suggests that it is worth reconsidering its role in the context of a broader approach to performance evaluation.@e$g0
