DIFFERENTIAL DEPRECIATION AND THE 2 <b>×</b> 2 MODEL OF DISTRIBUTION, PRICING AND PRODUCTION
In a two-sector model it is entirely arbitrary to take the depreciation rate to be the same in both sectors; capital is being used differently in the two sectors! With differential depreciation rates factor-intensity-reversal can arise even when both sectors have a Cobb-Douglas technology. Efficient allocations do not involve mutual tangency points between consumption-good and capital-good isoquants. Copyright Blackwell Publishing Ltd 2006.
