Bureau of Labor Statistics. She plugs in the numbers “$1000 in 1995 is worth xxxxx in 2005” and hits
“calculate” and gets back the number $1 ,281 .50. Is this adjustment for inflation smaller or larger than the
number Jeff calculates using the data beloW?

in the closed economy of Pastaville in the year 2008. Also assume that there are no additional inputs to
production besides those described below. In 2008, Farmer Frank produces 50 pounds of ﬂour, 50 pounds of eggs, and 50 pounds of tomatoes. In 2008, Tubby Tony, a hungry consumer, buys half (25 lbs) of Frank’s eggs at $2 per pound, and he buys half
of Frank’s tomatoes (25 lbs) at $4 per pound. He immediately eats all of the food he buys from Frank. In 2008, Restauratcur Ralph buys the rest of Frank’s output; 50 pounds of ﬂour at $1 per pound, 25 pounds of
eggs at $2 per pound, and 25 pounds of tomatoes at $4 per pound. Ralph uses all of his ﬂour and eggs to
produce pasta, and he uses all of his tomatoes to produce marinara sauce. In total, Ralph produces 100 pasta
and marinara sauce dinners, which he sells at his restaurant for $5 per dinner. a. Using the expenditure loop analysis and focusing on sales of ﬁnal goods and services, what is nominal value . . . Q

information it turns out that business is bad, and Ralph can’t sell the other 90 meals. In fact he only sells 70
meals in 2008. However, pasta dinners freeze nicely, so Ralph takes the 20 unsold meals and freezes them,
hoping to sell them in 2009 when business is better. How does this information impact on your calculation for the nominal value of GDP in Pastaville i11'2008? 3: ' ‘W If Cm w W \i "ink“ﬂ ‘ l 4 W is €19 £3
