Dopamine, serotonin and impulsivity.

Impulsive people have a strong urge to act without thinking. It is sometimes regarded as a positive trait but rash impulsiveness is also widely present in clinical disorders such as attention deficit hyperactivity disorder (ADHD), drug dependence, mania, and antisocial behaviour. Contemporary research has begun to make major inroads into unravelling the brain mechanisms underlying impulsive behaviour with a prominent focus on the limbic cortico-striatal systems. With this progress has come the understanding that impulsivity is a multi-faceted behavioural trait involving neurally and psychologically diverse elements. We discuss the significance of this heterogeneity for clinical disorders expressing impulsive behaviour and the pivotal contribution made by the brain dopamine and serotonin systems in the aetiology and treatment of behavioural syndromes expressing impulsive symptoms

Impacts of foreign policies on the gains from research and promotion

This paper compares the direct and indirect effects of rest-of-the-world (ROW) policy on welfare in country A: the direct effect due to the change in world price caused by the policy in the absence of research/promotion-induced shifts in supply/ demand, and the additional (or indirect) effect of the policy on the welfare gain to country A from its investment in research and promotion. The results showed that the reduction in aggregate economic benefits from research/promotion due to a world price-reducing policy in ROW could be in the range of 25-50% of the direct reduction in social welfare due to the ROW policy. In the case of Australian beef/veal, it is possible for the welfare impact of the ROW policy via research payoff in country A to exceed the direct welfare cost. © 1999 Elsevier Science B.V.

Chinese demand for Australian wheat : application of market share models

Changes in the market shares of Australian wheat in the Chinese import market over the period 1960/61 - 1989/90 were analysed using three modelling procedures. The empirical results indicate that, in addtion the relative price changes (P), retail availability index (R), which measures the total production in Australia relative to the average production in other wheat exporting countries, is important in determining market share changes. Market share is reported in all the models to be extremely price elastic both in the short and long run. Market share elasticity with respect to R is found to be inelastic in the short run but elastic in the long run
