| The long lag in the publication of input–output tables is one of the central constraints in applied general equilibrium analysis. Model builders often use out‐dated databases leading to analyses that are inappropriate for the policy questions being addressed. This occurs particularly when there exists a significant structural change in the economy. We discuss the updating of an input–output table of the Philippines by simulation technique. A detailed computable general equilibrium model of the Philippine economy with comparative static and forecasting capabilities is utilised. The data are drawn from known percentage changes of macroeconomic variables such as those in the national accounts and structural variables such as employment and output by industry. |

| Australia has long been a major exporter of wheat, a commodity well suited to the economic and climatic conditions of Australia. According to the conventional wisdom, Australia holds a comparative advantage in wheat. However, the future validity of this proposition is sensitive to the proposed impacts of climate change. This paper develops a framework with which to examine the future patterns of comparative advantage in wheat given the projections of several global climate models. We find support for the conventional wisdom, and identify the presence of substantial resilience in Australia’s comparative advantage to adverse yield change. |

| 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... |

| 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... |

| 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... |

| 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... |

| 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. |

| 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. |

| An hedonic price function is applied to Australia's wheat exports to the growing Asian markets. The values for the quality characteristics in the wheat markets of Indonesia, Malaysia, Singapore, South Korea, and Thailand are estimated. The data base for the study is from the Australian Wheat Board shipments over the period 1984 to 1991. The sample is divided into two separate time periods to test the consistency in demand for export wheat and to trace recent trends in quality premiums. The implications of the results for wheat marketing and trade are explored. |

| 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. |

| 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. |

| Entry to the Bachelor of Agricultural Economics (BAgrEc) program at the University of Sydney is consistently less competitive than that for the Bachelor of Economics (BEc) and Bachelor of Commerce (BComm) programs. Given that students in the BAgrEc program undertake units in common with students in the BEc and BComm programs, it is of interest to examine the importance of school performance and first year university in the determination of success at university. This paper takes information for nine cohorts of BAgrEc students and tests their performance in first-year core subjects against the university entrance ranking, school English and mathematics marks, gender, and type of school. The paper then uses the same information to predict which student... |

| 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... |

| 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. |
