From a middle-range theoretical perspective

From a middle-range theoretical perspective, entrepreneurs believed that introducing new innovations would increase their own profits and strengthen their competitive position. Motivated by this expectation, they invested resources, developed new products, and improved production methods. Because their actions helped bring about the very profits they anticipated, their belief became a self-fulfilling prophecy. The manifest function of innovation was therefore the achievement of private economic gain, which was the actors' intended objective. However, these same innovations also generated broader social benefits, including new jobs, increased productivity, improved living standards, and greater economic growth. These outcomes were not the primary goals of the entrepreneurs and thus constituted latent functions. In this way, the invisible hand illustrates how self-interested behaviour can fulfil intended personal objectives while simultaneously producing unintended consequences that contribute to social progress.
