My thoughts on this topic are as clear as most economics. I feel as globalization occurs and economies continue to grow the spectrum of specialization should continue to narrow. If one was able to graph this idea it would look like a concave function. As civilization began and many people never traveled outside of their village I can see the idea of corporations or families trading or individuals within families trading due to specialization. As economies grew and globalization started to progress countries could benefit from trading those goods that they were good at. Many factors could dictate which goods or services a country was efficient at but the main factors being raw materials and available labor. Now as globalization continues and the movement of goods becomes cheaper and more efficient, specialization at the corporate level seems to be more efficient than other spectrums. I am not stating that only one spectrum is present but the most efficient form of specialization seems to occur more at the present time and in the future with corporate specialization.
This theory seems accurate to me but is my graph right or is it different? Maybe it cycles.
