In genetic improvement programs, candidates for breeders are ranked by the profitability of their offspring, expressed as a weighted sum of the genetic gain from selection. In this paper, we estimate the economic values of a genetic improvement program for Australian farmed saltwater crocodiles. A bioeconomic profit function for a representative breeding pair is used to determine the optimal slaughter age following genetic improvement in each selection objective. The results indicate that estimated farm profitability increases by nearly # A111 for a 1-week reduction in juvenile slaughter age, # A78 for a 1 per cent increase in the proportion of first-grade skins produced, and # A33 for an increase in the number of viable hatchlings per clutch. The... |

Ryan challenges agricultural economists to help overcome a number of vexed problems facing the Australian wheat industry. Previous attempts to analyse these problems have been inadequate largely because of their inability to integrate real-world market imperfections and dynamics. Accordingly, there may be considerable merit in pursuing an alternative research agenda which employs non-traditional theories, models and estimation methods. Several alternative frameworks including the sunk cost model and strategic trade policy are proposed to address the issues of single desk selling status of the Australian Wheat Board and the US Export Enhancement Program. Additional problems including product differentiation, value adding and liberalisation in importing... |

The economics of a higher loan rate to support US wheat prices is analysed. Utilising optimal control theory, a dynamic wheat trade model is developed. The basic premise underlying the model is that the United States finds itself having transient monopoly power in the wheat market. An expression for the optimal pricing policy which maximises the present value of expected profits over the indefinite future is derived. Results from both the theoretical and empirical models demonstrate that the US wheat pricing strategy depends on its costs relative to competitors' costs, the discount rate and the competitors' response function. The main policy implication of the analysis is for the dominant wheat exporting country constantly to seek to lower costs relative... |

Constant market shares (CMS) analysis compares the actual export growth performance of a country with the performance that would have been achieved if the country had maintained its exports relative to some standard. The approach was first applied to international trade in the 1950s and has generally been used to analyse trading patterns and, in particular, the extent to which poor export performance can be attributed to a loss of ‘competitiveness’. However, the approach has been open to objections as a tool of description and diagnosis. Recent revisions appear to meet objections concerning its role as a descriptive tool. However, CMS analysis remains open to objections as a diagnostic tool owing to the strict theoretical conditions required to yield an... |

The elasticity of price transmission measures the extent to which a change in world prices will be transmitted to an importing country, with an elasticity of less than one being attributed to trade barriers. Recent research highlights the role that multinational trading companies may play in impeding price transmission. Further, in markets characterised by monopolistic competition an estimate of the partial elasticity of demand may be of limited practical value if no account is taken of the reaction of competitors. In this paper the potential for market structure to affect price transmission and trade elasticities is demonstrated. The elasticity of price transmission has been central to a revised approach to estimation of trade elasticities and has been... |

This article evaluates the impact of deregulation on wheat growers. marketers and buyers. An analysis of market structure focuses on the market prior to deregulation, the stimulus for change and the ways in which parts of the wheat marketing chain have developed since deregulation. The change in AWB pool deductions for storage, handling and transportation charges, and the consequent change in seasonal marketing margins since deregulation are explored. The main finding of this preliminary study is that deregulation has been associated with reductions in freight and handling charges as well as seasonal marketing margins. Factors other than deregulation appear to have contributed to the reduction in the marketing margin and would bear further investigation. |

This paper seeks to investigate the interaction between favoritism and allocative efficiency. The issue of whether corruption distorts allocative efficiency in a bribery game under a pre-existing environment of alleged favoritism is considered. It is demonstrated that if there is no unambiguous favoritism, observed favoritism in bribery game may disrupt allocative efficiency. A bribery game under corruption and favoritism is developed. The model and some possible equilibria are discussed. A simple numerical example from Lebanon is also presented. |

The present paper surveys various methods used to analyse market power in the retail food industry. The strengths and weaknesses of these approaches are explored and a review of the issues in using New Empirical Industrial Organization (NEIO) and time-series models is provided. The absence of a theory underlying time-series models is highlighted and a review of some theoretical models in retailing is presented. The impact of imperfect competition in the food processing sector on retailing is also examined. It is argued that a combination of the approaches that minimises the weaknesses and builds on the strengths of single approaches may prove more promising for examining non-competitive behaviour. |

As a signatory of the General Agreement on Tariffs and Trade (GATT), Australia is permitted to impose duties on goods that have been imported below 'normal value' and have caused or threatened to cause 'material injury' to the domestic industry producing 'like goods'. There has been a recent push from various industries to increase protection for producers who have been injured by such practices. The Government is concerned, however, that harsher anti-dumping regulations will damage its position in the Uruguay Round of the GATT negotiations. As a result, a Senate Inquiry was established in 1990 to review Australia's anti-dumping legislation. The objective of this paper is to examine the effectiveness of the public policy process in addressing this issue.... |

There has recently been much soul searching among US agricultural economists concerning future directions of the American Agricultural Economics Association. In Australia, however, little direct attention has been paid to the Australian Agricultural Economics Society. Utilising an industrial organisation framework, this paper seeks to investigate issues pertaining to the structure, conduct and performance of the Society. To that end, a survey of members was recently undertaken. This information, along with the views of Past Presidents of the Society, minutes of previous Annual General Meetings and student feedback on the future direction of the profession, is used as the main database for the analysis. The results suggest that, while demand for the product... |

Using the results of the first part of their 1994 membership survey, Ahmadi-Esfahani and Brakey (1996) examined the structure, conduct and performance of the Australian Agricultural and Resource Economics Society qualitatively. This paper extends that analysis by appraising some current trends in the Australian agricultural economics profession quantitatively. It concentrates on the second part of the survey to address a number of fundamental questions. A comparison of the US and Australian agricultural economics professions is made. The implications of the analysis for the product mix of the Society are explored. |

Concerns about the recent trends away from the consumption of red meat have led to tests for structural change in demand. These tests have typically treated the individual meats as homogeneous commodities. This article uses disaggregated data to test for structural change in the demand for differentiated meat products in Sydney over the seasons from winter 1987 to autumn 1991 using a revealed preference approach. The results fail to provide any evidence of structural change. |

A simulation model is employed to find the least cost way of dealing with the grain carryover during and after completion of harvesting that is caused by a difference between harvesting and trucking capabilities in the short run. The study may potentially aid the farmer in the face of legislative changes affecting wheat marketing, as well as technological changes in harvesting equipment. Results tend to indicate that temporary paddock storage may be more efficient than contract trucking in managing the carryover. |

In this paper, we generalise the constant market shares (CMS) framework, with particular attention to the underlying theoretical conditions required for diagnostic interpretation. The approach is applied to the analysis of the export performance of the Australian processed food sector in South-East Asia over the period 1980–2003. We conclude that the usefulness of CMS analysis for evaluating a country’s international trade performance depends upon the empirical validity of the aggregation assumptions implicit in the diagnostic interpretation. |

This study seeks to estimate the rate by which inputs in Australian pig production are substituted for one another when prices change. It employs a dual approach to response analysis. Using cost shares of inputs and input price indexes for the period 1977-78 to 1990-91, a set of equations derived from a transcendental logarithmic function is estimated with symmetry and homogeneity constraints imposed. The results indicate that, with the exception of the demand for feed which is a vital production input, pig producers are very responsive to own price changes. The estimated elasticities generally differ in magnitude from similar studies of the Australian agricultural sector, and suggest that, at a lower level of aggregation, farmers are more flexible in... |
