Water policy reform in Australia: lessons from the Victorian seasonal water market*

The nature of the seasonal water market is examined using a theoretical model and empirical evidence from the Victorian market. Drivers of the seasonal opportunity cost of water include the underlying nature of investment in the industry made in the context of risky entitlement yields; and the timing and nature of information regarding seasonal water availability and rainfall. Seasonal water markets facilitate the re‐allocation of water availability according to this short‐run opportunity cost. Evidence from the market suggests that transactions costs are low and most of the existing constraints to trade in seasonal allocations are the result of hydrological conditions. Analysis of market data suggests that the price response of the market to water availability is much more pronounced in years of low rainfall. The implications of the paper for wider policy reform are that attention should be paid to improving property rights for the management of intertemporal risk before other reforms, such as broadening of permanent water markets and institutionalising environmental flows, are implemented. This is because these other reforms will change the spatial and temporal pattern of water use and thus affect reliability, which underpins the value of water in irrigated agriculture.     

Towards a tax constitution for Leviathan

This paper attempts to derive normative tax rules based on the constitutional calculus of the typical voter–taxpayer when he predicts that post-constitutional political processes will be dominated by a budget-maximizing Leviathan-like bureaucracy. In this setting, selection of tax institutions becomes part of the apparatus by which Leviathan is constrained. Such an approach generates tax rules strikingly at variance with more conventional norms. In particular, the goal of a ‘comprehensive’ tax base, which informs standard analysis, gives way to a preference for specific limitations on the width of the tax base: moves towards a greater comprehensiveness will lead inexorably to larger public spending, and beyond some point are clearly undesirable. The analysis also implies a rather unconventional defense of progression in the tax structure. An attempt is made to relate the discussion to contemporary tax reform issues.     

The nature of local area social exclusion in England and the role of the labour market

The creation of the Social Exclusion Unit by the present governmentin 1997 is just one example of the increased desire by bothacademics and policy-makers to understand more about the factorsthat lead to individuals and communities becoming excluded frommainstream society. Of the many aspects of social exclusionwhich have featured in recent debate, this article focuses ontwo. The first is to describe the nature and the extent of socialexclusion in the areas in which it is concentrated in the UnitedKingdom. The second is to examine the role that labour-marketfactors play in creating, reducing, or sustaining geographicalconcentrations of social exclusion. The article draws upon theresults of social surveys conducted in deprived areas and discussesthe arguments for tackling local concentrations of social exclusionthrough area-based initiatives.     

Determinants of GNMA Mortgage Prices

This paper contrasts three different arbitrage-based models for the pricing of GNMA securities, and analyzes the effect of different assumptions about the call policy pursued by the issuers of the underlying mortgages. Both the nature of the interest-rate uncertainty captured by the model and the assumed call policy have a major effect on the yield differentials predicted between GNMA securities and Treasury Bonds.     

Cross-subsidization and cost misallocation by regulated monopolists

While cross-subsidization is understood theoretically as involving the sustainability of a cost allocation scheme, it is invoked in regulatory policy contexts, such as the divestiture of AT&T, where costs of serving unregulated markets may be borne by ratepayers of regulated monopolies. We analyze two cross-subsidization tactics—cost misallocation and distorted technological choice — under a spectrum of regulatory cost allocation policies. These tactics lead to higher prices in regulated markets and inefficient production in unregulated markets. Welfare effects are discussed; we conclude with observations on strategic behavior and regulatory policy.     

Incremental costs associated with myocardial infarction and stroke in patients with type 2 diabetes mellitus: an overview for economic modeling

Objective:

To identify cost estimates related to myocardial infarction (MI) or stroke in patients with type 2 diabetes mellitus (T2DM) for use in economic models.

Methods:

A systematic literature review was conducted. Electronic databases and conference abstracts were screened against inclusion criteria, which included studies performed in patients who had T2DM before experiencing an MI or stroke. Primary cost studies and economic models were included. Costs were converted to 2012 pounds sterling.

Results:

Fifty-four studies were identified: 13 primary cost studies and 41 economic evaluations using secondary sources for complication costs. Primary studies provided costs from 10 countries. Estimates for a fatal event ranged from £2482–£5222 for MI and from £4900–£6694 for stroke. Costs for the year a non-fatal event occurred ranged from £5071–£29,249 for MI and from £5171–£38,732 for stroke. Annual follow-up costs ranged from £945–£1616 for an MI and from £4704–£12,926 for a stroke. Economic evaluations from 12 countries were identified, and costs of complications showed similar variability to the primary studies.

Discussion:

The costs identified within primary studies varied between and within countries. Many studies used costs estimated in studies not specific to patients with T2DM. Data gaps included a detailed breakdown of resource use, which affected the ability to compare data across countries.

Conclusions:

In the development of economic models for patients with T2DM, the use of accurate estimates of costs associated with MI and stroke is important. When country-specific costs are not available, clear justification for the choice of estimates should be provided.     

A theory of search with deadlines and uncertain recall

We ask how the ability to recall past prices affects the dynamics of search and price formation. In the model, buyers have limited time to purchase a good and face uncertainty regarding the availability of past price quotes in the future. Sellers cannot observe a potential buyer’s remaining time until deadline nor her quote history, and hence post prices that weigh the probability of sale versus the profit once sold. We find that, in contrast to conventional wisdom, reducing the consumer’s recall ability may actually improve his expected utility because it lowers the average expected price in the market and reduces the duration of search.     

The End of Corporate Social Responsibility: Crisis & Critique,by Peter Fleming and Marc T. Jones

ABSTRACT

Purpose: Given the ever-increasing pressure put on sales organizations to improve performance, behave ethically and establish long-term customer relationships, this study seeks to better comprehend ethical leadership’s part in doing so. It proposes that perceived ethical leadership indirectly influences salesperson performance through trust in manager and ethical ambiguity.

Methodology/Approach: A survey of business-to-business salespeople was taken. Hypotheses are tested using structural equation modeling.

Findings: The results show that perceived ethical leadership influences salesperson performance through the mediating roles of trust in manager and ethical ambiguity. Salespeople’s perceptions of their supervisor’s ethical leadership behaviors positively impact their trust in manager and negatively influences their ethical ambiguity. In turn, trust in manager positively influences sales performance while ethical ambiguity negatively influences sales performance.

Research Implications: The results from testing the hypothesized model support mechanisms by which ethical leadership behavior may affect business-to-business salesperson job performance. It appears that ethical leadership works through ethical ambiguity and trust in manager to impact salesperson behavior performance, rather than directly impacting salesperson performance. Importantly the findings add to the literature an important consequence of ethical leadership, ethical ambiguity. This research likewise adds to the literature on role, and more specifically ethical, ambiguity by finding that reducing salesperson ethical ambiguity has a positive impact on salesperson behavior performance.

Practical Implications: This study finds that one important mechanism for reducing ethical ambiguity is for sales supervisors to practice ethical leadership. By reducing ethical ambiguity, sales managers can improve business-to-business salesperson performance. In addition, use of ethical leadership by sales managers can positively influence the business-to-business salesperson’s trust in manager, which subsequently leads to greater sales performance.

Originality/Value/Contribution: The results of this study add to our knowledge of ethical leadership by further developing its consequences. It also sheds light on a vastly under-researched construct, ethical ambiguity. Finally, it further validates the important role that trust in manager plays in the organization.
