We all hate to bring small change to the store. Usingrandom numbers, we can eliminate the need for change andgive the store and the customer a fair shake.a Suppose you buy something that costs $.20. How
could you use random numbers (built into the cash reg-ister system) to decide whether you should pay $1.00 or
nothing? This eliminates the need for change!b If you bought something for $9.60, how would youuse random numbers to eliminate the need for change?c In the long run, why is this method fair to both thestore and the customer?
Given the following panel data model
Y = Bo + B1X + a; + U
which of the followings is(are) correct?
Yanıtınız:
a, refers observable fixed effects while u, refers to unobservable fixed effects.
a, and u are both unobservable.
We cannot estimate B, if X, is time varying.
O We cannot estimate the model if some individuals are dropped from the data.
Bad simulations Explain why each of the followingsimulations fails to model the real situation properly:a) Use a random integer from 0 through 9 to representthe number of heads when 9 coins are tossed.
b) A basketball player takes a foul shot. Look at a ran-dom digit, using an odd digit to represent a good shot
and an even digit to represent a miss.c) Use random numbers from 1 through 13 to represent thedenominations of the cards in a five-card poker hand.
