Spreading rate of spilled liquid A contract engineer at DuPont Corp. studied the rate at which a spilled volatile liquid will spread across a surface (Chemical Engineering Progress. January 2005). Assume 50 gallons of methanol spills onto a level surface outdoors. The engineer used derived empirical formulas (assuming a state of turbulent-free convection) to calculate the mass (in pounds) of the spill after a period of time

Another issue facing millennials is the growing income and wealth inequality. We will use our model to understand the implications of this issue. A. Begin from the baseline preferences and endowments. Assume Xavier is wealthier than Yuri. Xavier has an endowment of 1100 pounds for each period (E1=E2=1100). Yuri has an endowment of only 900 pounds in each period (E1=E2=900). Note that each period's market supply is unchanged (1100 + 900 = 1000 + 1000 = = 2000).
