Really hard numbers: ANU economists create a DYI free-trade impact model

Tom Kompas and ANU colleagues have built the first large scale model with inter-temporal rules (how decisions at one point in time shape future circumstances), which countries can use to assess the decades-long impact of free trade deals. “Since our model is inter-temporal, producer and consumer behaviour is optimised in the long-run, thus enabling us to simulate, in particular, producers’ anticipation of future tariff reductions, taking into account future investment decision in advance,” they write

They tested the model for Vietnam in a free-trade scenario, using the Trans Pacific Partnership agreement and found, “Vietnam gains considerably from the TPP, with 50% of the gains realised within the first ten years despite our assumption of a gradual and linear removal of trade barriers.”

All good, even better the model is universal – plug in the data and get results for country of choice. Professor Kompas says the model, published in journal Economic Modelling is available free for the next 50 day.
