✦ Synopsis

The environmentally sensitive properties of polyethylene membranes filled with SiO, have been studied. The porous characteristics of the membranes is investigated with the aqueous solutions of pH 1-8 and aqueous electrolyte solutions with concentrations of 10-5-10-' moll L. The experimental results are explained by the concept of coagulation-swelling behavior of the filler under different environmental conditions. The relaxation of membrane resistance with a change in pH is also studied.

We determine empirically how automakers accommodate shocks to demand. Using data on production, sales, and transaction prices, we estimate a dynamic profit maximization model of the firm. We demonstrate that when an automaker is hit with a vehicle-specific demand shock, sales respond immediately and
