Bakrie, an Indonesian conglomerate, is assessing the likely consequences of the rupiah's steady decline on its different businesses. These businesses include a telecommunications company that is building a network (using mostly imported equipment) throughout Jakarta to offer wireless service to its residents, a company that sells pipe to the Western firms exploiting Indonesia's oil and gas fields, and a big agricultural business (54% of its revenues are in dollars, compared with 40% of its costs) that owns rubber and palm plantations feeding a large refining and distribution operation.

Assess the likely impact of the rupiah's depreciation on Bakrie's three different businesses.

Which of Bakrie's businesses will be most hurt by the rupiah's fall? Will any of these businesses actually benefit from rupiah depreciation?
