An evolutionary economic perspective on technical change and adjustment in cane harvesting systems in the Australian sugar industry

Australian sugar-producing regions have differed in terms of the extent and rate of incorporation of new technology into harvesting systems. The Mackay sugar industry has lagged behind most other sugar-producing regions in this regard. The reasons for this are addressed by invoking an evolutionary economics perspective. The development of harvesting systems, and the role of technology in shaping them, is mapped and interpreted using the concept of path dependency. Key events in the evolution of harvesting systems are identified, which show how the past has shaped the regional development of harvesting systems. From an evolutionary economics perspective, the outcomes observed are the end result of a specific history.     

Market Failures in Real-Time Metering

Policies to promote real-time metering (RTM) require more than showing benefits from more timely responses to variations in cost. They require positive externalities to imply that too few meters would be installed through private transactions. RTM presents no systematic externalities when utilities must serve peak period users, and may present negative externalities under some conditions. Positive externalities are likely when electricity is rationed through blackouts. RTM may or may not increase welfare when peak period wholesale markets are not competitive; a prohibition on RTM might be appropriate in such situations even if metering itself were costless.     

A consumer education programme based on the Transtheoretical Model of Change

MONEY 2000? is a successful consumer education programme that was implemented by Cooperative Extension personnel in over two dozen states of the USA between 1996 and 2002. One of the unique features of this programme is that it was based on the Transtheoretical Model of Change (TTM), a framework that has been widely used to study health‐related behaviour changes such as smoking cessation. This paper first describes how the MONEY 2000? programme was developed around major constructs contained within the TTM. Findings are reported from a survey conducted with participants in the first two states that delivered the programme. The findings suggest that several change processes used by MONEY 2000? participants are associated with specific stages of change. In addition, there may be differences in behavioural changes between participants who increased their savings and those who reduced their debts.     

Expressive Constitutionalism

We argue that the standard Constitutional Political Economy defence of constitutionalism, that derives from an argument relating to the shift from narrowly self-interested motivations in the in-period context to relatively general-interest decision making in the constitutional context, is flawed precisely because it is intended to relate to essentially political settings where decision making must be construed as collective in nature. We suggest an alternate account of expressive constitutionalism that points to a specific defence of constitutional conventions that are insulated from popular voting.     

A cost analysis of SIR-Spheres yttrium-90 resin microspheres versus tyrosine kinase inhibitors in the treatment of unresectable hepatocellular carcinoma in France,Italy, Spain and the UK

Abstract

Background and aims: A wide range of treatment options are available for hepatocellular carcinoma (HCC), including systemic treatment with tyrosine kinase inhibitors (TKIs) such as sorafenib and lenvatinib, immunotherapies, locoregional therapies such as selective internal radiation therapy (SIRT) and treatments with curative intent such as resection, radiofrequency ablation and liver transplantation. Given the substantial economic burden associated with HCC treatment, the aim of the present analysis was to establish the cost of using SIRT with SIR-Spheres yttrium-90 (Y-90) resin microspheres versus TKIs from healthcare payer perspectives in France, Italy, Spain and the United Kingdom (UK).

Methods: A cost model was developed to capture the costs of initial systemic treatment with sorafenib (95%) or lenvatinib (5%) versus SIRT in patients with HCC in Barcelona Clinic Liver Cancer (BCLC) stages B and C. A nested Markov model was utilized to model transitions between progression-free survival (PFS), progression and death, in addition to transitions between subsequent treatment lines. Cost and resource use data were identified from published sources in each of the four countries.

Results: Relative to TKIs, SIRT with SIR-Spheres Y-90 resin microspheres were found to be cost saving in all four country settings, with the additional costs of the microspheres and the SIRT procedure being more than offset by reductions in drug and drug administration costs, and treatment of adverse events. Across the four country settings, total cost savings with SIR-Spheres Y-90 resin microspheres fell within the range 5.4–24.9% and SIRT resulted in more patients ultimately receiving treatments with curative intent (4.6 vs. 1.4% of eligible patients).

Conclusion: SIR-Spheres Y-90 resin microspheres resulted in cost savings relative to TKIs in the treatment of unresectable HCC in all four country settings, while increasing the proportion of patients who become eligible for treatments with curative intent.     

The Challenges of Climate Policy

Climate policy planners and the public should be aware of both economic challenges and arguments that may influence the intensity of the climate policies with which they have to cope. This article examines six economic challenges: cap‐and‐trade versus taxes, non‐price regulations, energy efficiency policies, mitigation versus adaptation, trade effects, and transmission planning. Three additional challenges affect the end itself: ‘fat tails’, discount rates, and whether environmental protection should be evaluated by willingness to pay. If future generations cannot compensate the present for climate policy costs, climate policy is inherently redistributive and cannot be evaluated through cost–benefit analysis alone.     

Rhetoric, argument and impression management in hostile takeover defence documents

This exploratory study extends the analysis of narrative disclosures from routine reporting contexts such as annual reports and press releases to non-routine takeover documents where the financial consequences of narrative disclosures can be substantial. Rhetoric and argument in the form of impression management techniques in narrative disclosures are examined. Prior thematic content analysis methods for analysing good and bad news disclosures are adapted to the attacking and defensive themes in the defence documents of target companies subject to hostile takeover bids. The paper examines the incidence, extent and implications of impression management in ten hostile takeover defence documents issued by target companies listed on the London Stock Exchange between 1 January 2006 and 30 June 2008. Three impression management strategies – thematic, visual and rhetorical manipulation – are investigated using content analysis methodologies. The findings of the research indicate that thematic, visual and rhetorical manipulation is evident in hostile takeover defence documents. Attacking and defensive sentences were found to comprise the majority of the defence documents analysed. Such sentences exhibited varying degrees of visual and rhetorical emphasis, which served to award greater or lesser degrees of prominence to the information conveyed by target company management.While exploratory in nature, this paper concludes with suggestions for future more systematic research allowing for greater generalisations from the findings.     

The political economy of public debt

Public debt (as opposed to current taxation) alters the inter-temporal pattern of tax rates??it reduces current rates and increases future rates. Accordingly, whether the share of the cost of a given public expenditure is reduced or increased by debt for a given individual depends on the time profile of that individual??s income (tax base) vis-à-vis others?? incomes. Therefore, given the age-profile of income in virtually all Western countries, individuals will tend to be better off under current taxes the younger they are. If (as most standard models of political economy assume) individuals vote according to their economic interests, and if they are tolerably well-informed, then the pattern of support for public debt will track age. And increases in the median age of the population will lead to larger public debt. In other words, public debt policy collapses to a kind of demographic politics. This explanation may, however, be sensitive to assumptions about motives for bequest. Specifically, if bequestors seek to leave positive bequests and are motivated exclusively by the lifetime consumption of their heirs (as well as themselves) then the aged may, under plausible assumptions about the age of their heirs, prefer current taxes over debt.
