Ownership and control of Maori land: Some lessons for South Africa

New Zealand replaced customary tenure of Maori land with titles. Some issues are relevant to South Africa. Massive redistribution of Maori land is accounted for by inadequate property rights conferred fay colonial legislation. Institutions emerged to deal with problems of landlessness and low farm incomes created by titling, among which private incorporations and trusts were particularly successful Such institutions may under certain conditions be useful to smallholders in the former homelands and to groups of farmers who acquire freehold land in South Africa.     

The cost of quality in existing housing: Estimates from an implicit markets model

Rosen's implicit markets approach is used to model and estimate the cost of improving the state of repair of rental housing in existing structures. Particular attention is devoted to potential errors in the measurement of state of repair and to the inconsistent estimates of supply and demand parameters implied by Rosen's original econometric technique. Cost estimates imply that improvements in low-income housing could be provided much less expensively in existing housing than by either public new construction or the Section 8 existing housing program.     

Purchasing Competence: A Stakeholder‐Based Framework for Chief Purchasing Officers

A specific research stream within the purchasing and supply management literature focuses on the development of purchasing competence frameworks. We apply stakeholder theory and multiple methods of data collection to develop and confirm a hierarchy‐specific purchasing competence management framework for Chief Purchasing Officers and validate it using confirmatory factor analysis on empirical data from 124 multinational companies. The results reveal a significant relationship between Chief Purchasing Officers purchasing management competence and different purchasing performance measures confirming the appropriateness of stakeholder theory for such a competence framework.     

The CES‐‐Translog Production Function, Returns to Scale and AES

The translog functional form imposes no a priori restrictions on the substitution possibilities between the factor inputs, by relaxing the assumption of strong separability, and the CES–translog cost function specification allows for testing homothetic technology with Hicks‐neutral technical change. In this paper an n ‐factor CES–translog production function is presented which develops the parameters to directly assess scale effects from those due to technology in the production structure. In addition, by applying Shephard's lemma it was possible to derive the input demand functions, as well as the partial elasticities of substitution and the cross‐partial price elasticities of demand for a generalized CES–translog production structure.     

Are we overconfident in executive overconfidence research? An examination of the convergent and content validity of extant unobtrusive measures

Building understanding of overconfident executives is central to a growing literature that spans a number of disciplines. Much of this research has utilized unobtrusive, or indirect, measures to assess executive overconfidence from secondary data sources. We analyze the convergent and content validity of seven extant unobtrusive measures of executive overconfidence. The results of our analyses indicate that these measures do not exhibit adequate convergence, suggesting that existing measures are not measuring the same construct. Further, we administer a sort task to academic colleagues to assess whether scholars believe that the seven measures are adequately assessing the intended construct. The results of our sort task indicate that scholars did not categorize any of the seven measures as sufficient for measuring overconfidence. We conclude with suggestions for future research to address the inadequate convergent and content validity found in our assessment of extant measures of executive overconfidence.     

Homeownership, committed expenditure risk, and the stockholding puzzle

Kimball (1991) showed that consumers who face an unavoidablerisk will display 'temperance', meaning that they will increasetheir holdings of safe assets. In principle, temperance couldprovide an explanation for the stockholding puzzle, which isthe microeconomic manifestation of the equity premium puzzle.Previous work has shown that the temperance effect induced bylabor income uncertainty is too small to explain the stockholdingpuzzle. This paper finds that committed expenditure risk associatedwith homeownership induces enough additional temperance to explainthe puzzle.     

How do leaders' perceptions of organizational health climate shape employee exhaustion and engagement? Toward a cascading-effects model

Although researchers and practitioners increasingly focus on health promotion in organizations, research has been mainly fragmented and fails to integrate different organizational levels in terms of their effects on employee health. Drawing on organizational climate and social identity research, we present a cascading model of organizational health climate and demonstrate how and when leaders' perceptions of organizational health climate are linked to employee well-being. We tested our model in two multisource studies (N_{Study 1} = 65 leaders and 291 employees; N_{Study 2} = 401 leader–employee dyads). Results showed that leaders' perceptions of organizational health climate were positively related to their health mindsets (i.e., their health awareness). These in turn were positively associated with their health-promoting leadership behavior, which ultimately went along with better employee well-being. Additionally, in Study 1, the relationship between perceived organizational health climate and leaders' health mindsets was moderated by their organizational identification. High leader identification strengthened the relationship between perceived organizational health climate and leaders' health mindsets. These findings have important implications for theory and practice as they show how the dynamics of an organizational health climate can unfold in organizations and how it is related to employee well-being via the novel concept of health-promoting leadership.
