Trade and invasive species risk mitigation: Reconciling WTO compliance with maximising the gains from trade

This paper analyses the issue of balancing the gains from trade with the risk of pest and disease transference. Two decision frameworks for determining whether or not to permit trade in a potentially invasive species-carrying good are presented. The first considers only the potential production losses resulting from an invasive species entering through a trade pathway, as is prescribed by WTO compliance. The second is a unilateral welfare-maximising approach which considers the consumer gains from trade, the loss of domestic producers’ market share and expected damage from the invasive species. It is shown that these alternative decision frameworks can be reconciled such that they produce the same outcome regarding whether or not trade is to be permitted. The key parameters which influence these decisions are also highlighted.     

Targeting Monitoring Resources to Enhance the Effectiveness of the CAP

From its inception the operation of the CAP has required the compliance monitoring of farming activities and anticipated increases in the complexity of the monitoring tasks with the introduction of the SFP will stretch monitoring resources even further. We outline the scope for using targeting to enhance effectiveness of monitoring resources in dealing with non-compliant behaviour. Targeting resources can increase information on particular groups making identification of inappropriate behaviour easier. However, in reallocating monitoring resources towards the targeted sub-group, there is likely to be an associated reduction in resources allocated to monitoring non-targeted agents and therefore an increase in their incentive to cheat. To reduce this problem we suggest balancing the targeting-induced reduction in the probability of being caught cheating for non-targeted agents with an appropriate increase in the penalty for those agents if they are caught cheating. This increase in penalty results in an increased divergence between the outcomes from being caught or not caught cheating for non-targeted agents, which increases the overall perceived risk of the cheating option. And for risk-averse agents, this increase is a disincentive to cheating. On this basis we argue for greater use of target-based compliance monitoring as part of the revised and evolving CAP.     

Experimental Evidence on Alternative Environmental Valuation Methods

Experimental methods are central to assessments of environmental valuation approaches that are operationally meaningful. Existing lab experiments focus attention sharply on the neglect of hypothetical bias. They also offer constructive solutions to correct this bias, and beg for validation in field experiments.     

OPTIMAL GROWTH STRATEGIES FOR PASTORAL FIRMS IN THE QUEENSLAND BRIGALOW SCHEME

The Brigalow Scheme has been one of Australia's largest dryland development projects since World War II. Large sums of private and public capital have been invested to create 247 new farm firms. Planning the development of these new properties is a complex task. A simulation model of the typical block in Area III of the Brigalow Scheme has been constructed and used to evaluate experimentally the financial performance of various growth strategies. Use of a conjugate directions search procedure with this model has allowed growth strategies to be identified which maximize net worth subject to a low risk of financial failure. These strategies are compared with development programmes which have already been implemented. Significant conclusions are reached both with respect to future management strategies and future land development policies. Methodological advances incorporated in the simulation model are also discussed.     

Returns to scale and externalities in the consumption and investment sectors

Using data on US manufacturing, I estimate internal returns to scale and external effects for the consumption and investment sectors. I construct panels of data at the industry level and use results of gross output production function estimation to derive implied estimates in a value added specification. For the investment sector, returns to scale appear to be slightly increasing, with evidence of a positive external effect. For consumption, the evidence indicates decreasing to constant returns to scale. I discuss the implications of these results for the empirical plausibility of indeterminacy in recent multi-sector models of the business cycle.     

Is a Long‐term Business Relationship an Implied Contract? Two Views of Relationship Disengagement*

ABSTRACT Current knowledge of business‐to‐business relationship dissolution centres upon definitions of relationship dissolution, models of dissolution, antecedents for dissolution, and dissolution strategies. In this paper an empirical case example of a terminated business relationship in the aftermath stage of the dissolution process is presented. William Baird sued Marks and Spencer for £53.6 m for breach of contract. The relationship between the actors was long‐term, exclusive, and involved substantial investment in specific assets. There was no written contract in place, yet one actor considered that the relationship was equal to an implied contract. The contribution of the paper is to discuss the possibility for legal redress using the transaction cost economics, relational contracting, and industrial networks literatures.     

THE PRIVATE FINANCE INITIATIVE IN LOCAL GOVERNMENT

This paper distinguishes between the Private Finance Initiative (PFI) and the more general Public Private Partnerships (PPP). It traces the growth of the initiative since its start in 1992 to the current day and considers the implications of PFI for the public finances. A number of economic issues are discussed including bidding costs, financing costs and whole life costing. The importance of risk transfer in the value for money analysis of PFI projects is emphasised and the extent to which risk actually is transferred is questioned. Finally, the contribution of PFI towards modernising public service is recognised but the Audit Commission's recommendation that a wider range of procurement tools ought to be considered is noted.
