2 a) If The Beer Store gets beer from the brewery, and the brewery gets its barley from the barley farmer, determine the value added at each stage using the following information: I. The farmer pays herself $1, pays rent of $2 to the landowner, and sells the barley to the brewery for $3. She does not buy any intermediate products. II. The brewer buys the farmer's barley for $3, pays his workers' wages of $2, sells the beer to The Beer Store for $6, and earns a profit of $1. III. The Beer Store buys the brewer's beer for $6, pays wages of $3, sells the beer to the final consumer for $10, and earns a profit of $1. (b) If the economy consists only of the farmer, the brewer, and The Beer Store, calculate GDP using the value-added approach. (c) Does Say's Law hold true in this example? [Hint: calculate aggregate income (of wages, profits, and rent) and compare it to aggregate spending.]
