Before revision:   Here, we show that fluctuations in growth for companies follow a power law with very similar scaling exponents, irrespective of the economic sector.
After revision:  Remarkably, work in econophysics has provided evidence that the statistical properties of the growth of business firms follow the same sorts of power laws that characterize physical systems near their critical points. Given how economies change over time, whether these statistical properties are persistent, robust, and universal like those of physical systems remains an open question. Here, we show that fluctuations in growth for companies follow a power law with very similar scaling exponents, irrespective of the economic sector.
