Suppose that electrical attraction, rather than gravity, were responsible for holding the Moon in orbit around the Earth. If equal and opposite charges Q were placed on the Earth and the Moon, what should be the value of Q to maintain the present orbit? Use data given on the inside front cover of thi

Consider a region with a single factory city that developed as a result of scale economies in production. Consider the effects of a new matter transmitter, which can instantly transport goods (but not people) from the factory to any consumer up to 12 miles away, with a zero marginal cost of transport

Teacher Isoquant and Cost Minimization Consider a teacher isoquant, which shows different input combinations that produce a target quantity of output. Suppose the inputs for teacher productivity are graduate course work (on the horizontal axis, ranging from 0 to 10 years) and verbal ability (on the v
