The Role of Entrepreneurship in US Job Creation and Economic Dynamism

Abstract

The United States has long been viewed as having among the world's most entrepreneurial, dynamic, and flexible economies. It is often argued that this dynamism and flexibility has enabled the US economy to adapt to changing economic circumstances and recover from recessions in a robust manner. While the evidence provides broad support for this view, the outcomes of entrepreneurship are more heterogeneous than commonly appreciated and appear to be evolving in ways that could raise concern. Evidence along a number of dimensions and a variety of sources points to a US economy that is becoming less dynamic. Of particular interest are declining business startup rates and the resulting diminished role for dynamic young businesses in the economy.We begin by describing how the concept of entrepreneurship is reflected in existing data on firm age and size. The recent addition of firm age to official statistics represents a dramatic improvement in the information available to entrepreneurship researchers. We then turn to a discussion of the role of startup firms in job creation. Business startups account for about 20 percent of US gross (total) job creation while high-growth businesses (which are disproportionately young)

Grown-Up Business Cycles

“…Reedy and Strom (2012) were the first to our knowledge to document the aggregate decline in employer firm and establishment entry. Along with our paper, contemporaneous work by Decker, Haltiwanger, Jarmin, and Miranda (2014a) and Hathaway and Litan (2014) also document both declines in the share of new firms nationwide and within sectors or markets, and the accompanying increasing share of older firms. Both papers suggest the two trends may be related.…”

“…Recent papers by Lazear and Spletzer (2012), Hyatt and Spletzer (2013), Decker, Haltiwanger, Jarmin, and Miranda (2014b) and Davis and Haltiwanger (2014) document ongoing declines in several measures of job and worker reallocation. Reedy and Strom (2012) were the first to our knowledge to document the aggregate decline in employer firm and establishment entry.…”

Personality Traits of Entrepreneurs: A Review of Recent Literature

“…There are often four-fold or larger differences in entrepreneurship rates across U.S. cities (e.g., Glaeser et al, 2015), and those for venture capital are even sharper (e.g., Samila and Sorenson, 2011). Moreover, the rate of new business formation is declining in Introduction the United States (e.g., Decker et al, 2014). Many business leaders and policy makers are looking to build better environments to support entrepreneurship, and this review highlights softer personality traits and risk attitudes that can be considered along with more typical factors like financing conditions.…”

Who creates jobs? Econometric modeling and evidence for Austrian firm level data

“…consequence, many contributions in the literature calculated average job creation rates at, for instance, age-size-industry-year cells and used the respective cell-means as observational unit in a regression framework estimated via (weighted) OLS (e.g., Dunne, Roberts and Samuelson 1989;Baldwin, Dunne and Haltiwanger 1998;Faberman 2003;Stiglbauer, Stahl, Winter- With the increasing availability of individual firm level data, recent research has adopted a micro-econometric framework for studying this question. This approach predominantly applies employment-weighted OLS estimation to one-and two-way model specifications for firm size and age dummies (e.g., Burgess, Lane, Stevens 2000;Haltiwanger and Vodopivec 2003;Voulgaris, Papadogonas and Agiomirgianakis 2005) and additionally includes interaction terms of these dummies (see, e.g., Haltiwanger et al 2013a;Decker, Haltiwanger, Jarmin and Miranda 2014;Geurts and Van Biesebroeck 2014). Some recent contributions extend this by including firm size and age as continuous variables (Lawless 2014) and/or augmenting the model with further explanatory variables such as initial firm size, GDP growth, domestic versus foreign ownership, productivity and profitability (Lawless 2014;Rijkers, Arouri, Freund and Nucifora 2014).…”
