Optimal consumption-wealth relationships derived by consumer intertemporal profit maximisation

This paper proposes an artificial intertemporal consumer profit-maximisation problem that is simple to solve. The optimal consumption function, which is consistent with intertemporal utility maximisation, is then generated directly from a specification of the consumer's instantaneous profit function.     

Technological inefficiency indexes: a binary taxonomy and a generic theorem

Over the years following Debreu’s (1951) seminal formulation of a “coefficient of resource utilization”, a large number of indexes of technological inefficiency have been specified and a spate of papers has examined the properties satisfied by these indexes. This paper approaches the subject more synthetically, presenting generic results on classes of indexes and their properties. In particular, we consider a broad class of indexes containing almost all known indexes and a partition of this class into two subsets, slacks-based indexes and path-based indexes. Slacks-based indexes are expressed in terms of additive or multiplicative slacks for all inputs and outputs, and particular indexes are generated by specifying the form of aggregation over the coordinate-wise slacks. Path-based indexes are expressed in terms of a common contraction/expansion factor, and particular indexes are generated by specifying the form of the path to the frontier of the technology. Owing to an impossibility result in one of our earlier papers, we know that the set of all inefficiency indexes can be partitioned into three subsets: those that satisfy continuity (in quantities and technologies) and violate indication (equal to some specified value if and only if the quantity vector is efficient), those that satisfy indication and violate continuity, and those that satisfy neither. We prove two generic theorems establishing the equivalence of these two partitions: all slacks-based indexes satisfy indication and hence violate continuity, and all path-based indexes satisfy continuity and hence violate indication. We also discuss the few indexes that do not belong to either of these two sets. Our hope is that these results will help guide decisions about specification of the form of efficiency indexes used in empirical analysis.     

The impact of internal marketing on the perception of service quality in retail banking: A Ghanaian case

Although there is a large volume of literature on internal marketing, there is limited empirical evidence on its impact on the perception of service quality in developing nations. A literature review of internal marketing and service quality has been completed. A survey of 32 top managers, 100 employees and 200 external customers of a major bank in Ghana was undertaken to assess the impact of internal marketing on the perception of service quality. The results suggest that internal marketing can have an influence on service quality. Implications of the study are highlighted, limitations noted and directions for future research are outlined.     

Duality and continuity

This paper fills the one remaining lacuna in (multiple-output) duality theory by provingjoint continuity (in input and output vectors) of cost, benefit, and (input and output) distance functions. Continuity is an important property where measurement error exists, for it provides assurance that small errors of measurement (of quantities or prices) result only in small errors in concepts like minimal cost. We consider continuity not only in prices and quantities, but also in technologies. Continuity in technologies might be more important than continjity in prices or quantities, because production technologies are almost certainly measured (or estimated) with error.     

Variations in hub service in the US domestic air transportation network

This paper looks at the various types of hubs that have evolved in the air transportation network in the USA. Since deregulation of the industry at the end of the 1970s, the major air carriers have expanded their networks to become more competitive, and the number and types of hubs have grown accordingly. A connectivity analysis using a traditional matrix approach is used to derive indices which are the basis for the development of a connectivity classification scheme. In addition, the various service functions of hubs are explored.     

Optimal Taxation in a Federal System of Governments

This paper demonstrates that the optimal structure of taxation in a federal system of governments is one in which only lower level governments are allowed to tax, and the higher level of government receives its revenues as contributions from the lower level governments. The central inefficiency created when multiple levels are allowed to tax is a revenue externality between governments that is analogous to a common pool problem. A federal system with multiple levels of taxing authority results in combined tax rates higher than would be optimal, a higher excess burden of taxation, and an inefficiency bias in government spending.     

SUPPLY CHAIN INTERFACES: DEFINING ATTRIBUTES AND ATTRIBUTE VALUES FOR COLLABORATIVE LOGISTICS MANAGEMENT

Managing supply chain interfaces, where information or physical goods are exchanged between one trading partner and another, is a key component of collaborative logistics management (CLM). Identifying the interfaces on which to focus, and describing the attributes and attribute values of these interfaces, fosters effective CLM arrangements.     

Interests, Institutions and Industrial Relations

In the comparative politics literature there are two main approaches to the impact of international economic change on national policy patterns. The first — new institutionalism — has been very influential in comparative industrial relations scholarship. The second, which focuses on the role of interests, has been less prominent. Comparing industrial relations reform in Australia and New Zealand during the 1980s and 1990s, this paper argues that there are a number of limitations to an institutionalist approach and outlines a framework for the comparative study of the impact of international economic change on national patterns of industrial relations which integrates both institutionalist and interest‐based approaches.
