    Per capita beer consumption in the country had been stable for many years. In order to find new opportunities for growth, Cerjugo management decided to expand their product lines into juices. They recognized early on that the juice business was very different from that of beer. In beer, there was little competition and profit margins were high, close to 40 percent.

The farming industry has had to ramp up production of corn to satisfy the demand that was caused by the increase in the number of buyers. More buyers will generate more income, so most likely farmland will be used to produce more corn. The determinants of Number of buyers and Income are responsible for this demand shift. The land available for soybean crops will decrease, resulting in a reduction of supply. This supply shift is the result of Producers (number of).…
