This article, written by Elaine Pofeldt, discusses how the United States has moved away from necessity entrepreneurship and towards opportunity entrepreneurship (perhaps because of economic development). According to Acs’ article, “Opportunity entrepreneurship represents the voluntary nature of participation and necessity entrepreneurship reflects the individual’s perception that such actions presented the best option available for employment.”
Acs uses the opportunity-necessity entrepreneurship ratio as a potential indicator of economic development. Pofeldt mirrors Acs by identifying that though a smaller percentage of the population is starting new businesses, “People who did start businesses in 2013 were more driven by opportunity–rather than necessity–than in recent years.” Pofeldt also includes statistics of who and which industries have experienced and increase in entrepreneurship.
