Prof. Dr. HildebrandtFunktionale Darstellungen 2 Verbale Darstellung There are in a pound upwards of four thousand pins of a middling size. Those ten persons, therefore, could make among them upwards of forty-eight thousand pins in a day. Each person, therefore, making a tenth part of forty-eight thousand pins, might be considered as making four thousand eight hundred pins in a day. But if they had all wrought separately and independently, and without any of them having been educated to this peculiar business, they certainly could not each of them have made twenty, perhaps not one pin in a day; that is, certainly, not the two hundred and fortieth, perhaps not the four thousand eight hundredth part of what they are at present capable of performing, in consequence of a proper division and combination of their different operations. Adam Smith

Prof. Dr. HildebrandtFunktionale Darstellungen 3 Verbale Darstellung The government agencies that collect data on manufacturing are well aware that the distinction is blurry. According to the Bureau of Labor Statistics, bakeries, candy stores, and custom tailors are all part of manufacturing. But one could walk into such a retailer and see many service activities taking place. Sometimes subtle differences can change how an activity is classified. Mixing water and concentrate to produce a soft drink is classified as manufacturing. If that activity is performed at a snack bar, however, it is considered a service. Gregory Mankiw
