1. Suppose Ben records the noon temperature in New York City on every day in the month of July, and Jerry records the noon temperature in New York City on every day in an entire year.
a) Which one (Ben or Jerry) would you expect to have the greater mean of temperatures, or would you expect the means to be very similar? Explain briefly.

3. Suppose we observe temperatures in several cities at noon on a particular day. The mean observed temperature is 20 degrees Centigrade; the standard deviation is 5 degrees. a) Degrees Fahrenheit are related to degrees Centigrade according to the formula (F = 32+1.8C). Suppose we were to convert the observed temperatures to degrees Fahrenheit. What would the mean temperature be in degrees Fahrenheit? What would the standard deviation be? b) Temperatures can be expressed in standard units. Suppose the temperature...

Amazon has announced that one of its new headquarters will be located in New York City and will create more than 25,000 full-time jobs. Suppose (for now) that there is no change in New York City’s population as a reaction to this announcement. (a) How would you expect the opening of the new headquarters to impact employment and wages in New York City? (b) Suppose that most of these new jobs are for skilled workers in highly technical occupations. How...

Suppose that every year the city of New York auctions off a limited number of medallions that give cab drivers an exclusive right to taxi in the city for one year. After receiving the medallion the cab driver is essentially a monopolist facing an inverse demand function p = 20 - 1.4Q. The total cost function for each cab driver can be summarized as C(Q) = 3Q + F. Where F represents the cost of the medallion or annual fixed...

3. Suppose the price elasticity of demand for subway trains in Boston and New York City is almost close to zero. If the city authority raises the fare of MBTA passengers by 20% over its current prices to cover the loss of operation of MBTA, how much increase in revenue do you expect due to fare increase of 20%? Give reasoning to substantiate your answer.

ExERCISE 3 In 1980, New York City had a more-or-less free market of taxi services. Any firm could provide a taxi service, as long as the drivers and cars satisfied certain safety standards Suppose the constant marginal cost per trip of a taxi ride is $5, and the average taxi has a capacity of 20 trips per day. Let the demand function for taxi rides be given by D(p) 1,200-20p, where demand is measured in rides per day, and price...
