Sometimes you see in advertisements statements like "... only 3 units remain in stock..." or, as in booking.com, "only 4 rooms left at this price..." and similar statements. Which effect do you think this has, if at all? Is it an effect on the supply side of the market (producers) or the demand side (consumers)? If the effect materializes, is it going to be a movement along the (supply or demand?) curve, or is it a shift of the respective curve (and, if so, is it rightward or leftward shift).

Given your answers above, draw basic upward-sloping supply and downward-sloping demand curves (in the Q-P space).
