Argentina's Currency Rules Backfire

``Apart from the minor inconveniences this has caused to shoppers, such as no longer being able to buy breakfast cereal not composed of shredded carpet, the measure has also backfired on Argentine industry itself because so many of the products manufactured in Argentina still need component parts and raw materials from elsewhere. Hence, for example, the 1,600 workers laid-off from the Renault car plant in Cordoba last June, while the parts they needed to finish the job languished in a container on a Buenos Aires quayside. But you do not need to be an economist to imagine the consequences when a G20 nation suddenly adopts North Korean-style siege-economy tactics, which does make you wonder about the quality of advice the government is getting.''
