The problem of predicting the effective elastic properties of multi-cracked and/or composite materials is both fundamental in materials mechanics and of large technological impact. In this paper we develop a continuum elasticity model, based on the Eshelby theory and on the differential...

Our IO approach links optimal effective corporation tax rates to the nature of sunk costs within industries. Theory predicts that optimal effective corporation tax rates will be negatively related to industry specific sunk cost, and hence industry concentration. Governments should tax industries...
