    Forward planning and stability of the Austrailan migration program
    (1995-02) Clarke, Harry
    Should the Australian immigration intake be forward planned and if so, should the resulting intake be numerically stubble through time? There are sound reasons for anticipating the effects of current on future immigration intakes decisions. Australia's long-term national objectives. These two policy requirements imply a case for forward planning but not the need for a stable immigration intake. Appropriately designed numerically unstable intakes are preferable to stable immgration intakes because instabillity, while introducing adjustment costs avoids incurring more significant losses due to loss of selectivity in determining the entry mix.

    Optimal air service agreements: a theoretical model
    (Latrobe University, 1995-02) Clarke, Harry
    Air service agreements are negotiated bilateral agreements defining nation's permitted passenger carrying capacity between origin and endpoint nodes on particular international air routes, This study examines the determination of economically optimal (rent-maximising) agreements under various demand and bargaining assumptions. The role of marketing and 'downstream' inter industry effects are accounted for and numerical examples of optimal agreements given.

    Optimal depletion when development makes an unused resource stock more valuble
    (1995-05) Clarke, Harry
    Some countries rapidly exploit their natural resource bases to increase incomes and achieve development goals. When increased incomes eventuate, stocks of certain resource currently being depleted attain enhanced future values when demands for the utilization of services based on theses stocks increase with development. This paper analyses the trade off between development and conservation goals in a model determining optimal savings and depletion time paths.

    Soil conservation with differential soil quality: Demand growth and the evolation of intensive and extensive margins
    (1995-02) Clarke, Harry
    results establishing a positive relationship between agricultural product demands and equilibrium soil quality are reestablished in a spatial setting where farmers utilise soils of different intial quality.The same positive equilibrium relationship emerage as optimal with a single reproducible fertility factor when soil fertility investmant costs are convex in the level of fertilizer application regardless of whether farmer spending is budget-constrained.Introducing non-reproducible intrinsic fertility leads to differential optimal fertiliser applications but the positive relation between soil quality and product price (or demand) remains.
