Volatility and Job Creation in the Knowledge Economy

Abstract: Summary Sectors with increasing returns to scale have been shown to amplify business cycles exhibiting more volatility than others [13]. Our hypothesis is that this volatility could be a cause of the “jobless recovery” suggesting policies for employment generation. To test this hypothesis we introduce a general equilibrium model with involuntary unemployment. The economy has two sectors: one with increasing returns that are external to the firm and endogenously determined — the knowledge sector — and the other with constant returns to scale. We define a measure of employment volatility, a ‘labor beta’ that is a relative of the ‘beta’ used in finance. A ‘resolving’ equation is derived from which it is proved that increasing return sectors exhibit more employment volatility then other sectors. The theoretical results are validated on US macro economic data of employment by industry (2–3 digits SIC codes) of the 1947–2001 period, showing that the highest ‘labor betas’ are in the service sectors with increasing returns to scale. Policy conclusions are provided to solve the puzzle of the ‘jobless recovery’, where small firms in the services industry play a key role. We conclude with policy recommendations on how to create jobs in the knowledge economy.
