How IT Impacts Agency Measurement, Market Focus, and the Labor Share

Does investing in info know-how (IT) allow companies to “scale with out mass” and enhance their market share? In a brand new paper, Erik Brynjolfsson, Wang Jin, and Xiupeng Wang study how IT impacts agency dimension, market focus, and the labor share of income.

Over the previous few many years, we have now witnessed important adjustments within the U.S. enterprise panorama. Firms are getting greater on common whereas dominant gamers in numerous industries proceed to extend their market shares. Utilizing the retail sector for example, the common business market share of the highest 4 companies has elevated from 30% within the Nineteen Nineties to above 40% within the 2010s. These firms have increased income whereas employees are getting a smaller share. In the meantime, technological progress has resulted within the widespread adoption of data know-how (IT) amongst U.S. companies. Might IT be the driving drive behind these developments? In our current working paper, we search to reply this query.  

Advances in IT have led to important value reductions in storing, transferring, and analyzing digital info. As highlighted by F.A. Hayek, each companies and markets could be considered as info processing programs. Due to this fact, the sharp decline in IT’s prices and its fast diffusion might be an essential driving drive of the change in financial organizations. As an example, IT performed an important function in catalyzing innovation in enterprise, particularly in provide chain administration, and helped Walmart to turn into a prime retail firm.

The results of IT on agency dimension are advanced. On the one hand, IT can result in smaller agency dimension by lowering the prices related to exchanging items and providers externally (e.g., effort and time concerned in negotiating and communication), encouraging companies to depend on market transactions. Enterprise adoption of IT may end in labor substitution and automation, lowering employment in companies.  

However, IT may enhance optimum agency dimension by making inner coordination cheaper and streamlined, selling hierarchical buildings and broader possession. For instance, CVS used IT to deploy and replicate a digital resolution in its 4,000 nationwide pharmacies. As well as, IT can scale back the prices of data switch and monitoring. By decreasing the price of co-locating resolution rights with info, IT can thus improve decision-making and enhance total effectivity. 

Due to this fact, the theoretical prediction on common agency dimension stays ambiguous and primarily depends upon which results prevail.

In our paper, we examine the connection between companies’ funding in IT and adjustments in agency dimension utilizing detailed micro-level information from 2004 to 2013, derived from a consultant pattern of U.S. companies primarily based on administrative information from the U.S. Census Bureau. We deal with the impression of IT on companies’ employment, income, and market share, in addition to its function in rising industrial focus in current many years. 

Elevated IT depth leads to increased employment and gross sales

Our research offers novel firm-level proof that IT depth (i.e., IT funding per worker) is related to bigger agency sizes on common, regarding each the degrees and shares of employment and income in current many years. The baseline outcomes reveal that, on common, each further $60 expenditure in IT per employee is related to a rise of two staff per agency and a rise of $1 million in income. Equally, when a agency will increase its IT depth, its market share tends to broaden, whether or not measured by employment or by income. Our outcomes are strong to a wide range of econometric fashions and various IT measures. Moreover, long-difference fashions spanning as much as 5 years and analyses utilizing instrumental variables—the share of sedentary employees on the business stage—each counsel that the recognized impact of IT on agency dimension is causal, with the outcomes particularly sturdy for agency income.

Elevated IT depth additionally results in decrease labor share of income

Whereas IT results in bigger agency sizes on all of the metrics we examined, its impression is most pronounced on companies’ income. This means that enhanced labor productiveness allows companies to extend gross sales with out proportionately hiring extra labor, aligning with the “scale with out mass” speculation. That’s, companies can scale up their manufacturing and broaden their operation by way of know-how by way of low-cost replication of enterprise processes with out the diploma of inertia related to bigger companies. We delve into the connection between IT and a agency’s labor share of income to disclose {that a} 1% enhance in IT depth is related to a 0.1% decline in labor share of income. 

IT helps companies broaden with extra institutions, native markets, and industries

IT allows companies to codify their operations, streamline the duplication of their enterprise processes throughout extra manufacturing models and markets, and in the end develop in dimension. We examine this mechanism utilizing our establishment-level information that covers companies’ operations throughout numerous industries and areas within the U.S. It seems that companies with increased IT depth are inclined to have a considerably bigger variety of institutions and are capable of broaden their operations throughout counties and industries. For instance, a 1% enhance in IT depth is related to a 0.03% enhance within the variety of institutions. Equally, IT is related to a rise within the variety of distinct zip codes and industries wherein companies function. These findings present supporting proof that the channels wherein IT contributes to rising agency dimension are by way of lowering the prices related to duplicating enterprise processes and enhancing inner coordination. 

Bigger companies profit extra from investing in IT

The character of IT, usually characterised by a excessive fastened value and low marginal value, permits bigger companies to make use of them extra effectively, benefiting from economies of scale. Furthermore, bigger companies additionally accumulate a better stage of tangible and intangible belongings that complement their IT investments. Consequently, the contribution of IT to a agency’s development might differ relying on the agency’s dimension. We estimate the consequences of IT depth on employment, gross sales, and labor share throughout dimension classes and plot them correspondingly in Determine 1. For every business, we categorize companies into quintiles primarily based on their place within the gross sales distribution. 

Panel A signifies that increased IT depth is related to elevated employment for all dimension quintiles, with a extra important impact on smaller companies. What’s extra, as a result of the common agency dimension rises shortly from the primary to the fifth quintiles, the elevated variety of staff related to IT will increase monotonically. 

In distinction, the consequences of IT on agency income enhance monotonically with agency dimension and are solely considerably completely different from zero for bigger companies, as introduced by Panel B. This means that though the common impact of IT on companies’ gross sales is perhaps optimistic, the disproportionately bigger achieve for bigger companies signifies an rising return to scale of IT funding. 

As proven within the first two panels, the disproportional good points from IT on gross sales (in comparison with employment) are extra pronounced amongst companies within the bigger dimension quintiles, which might naturally result in a decline in labor share on common. We quantified this impact in Panel C. The impression of IT on labor share for companies within the backside dimension quintile is optimistic however noisy. Such an impact declines throughout the dimensions classes, changing into adverse and extremely important for companies within the prime three. Given the intensive enterprise adoption of IT throughout numerous industries, our outcomes thus present supporting proof that IT is among the driving forces for the decline in labor share and the elevated focus over time.

The second machine age and IT adoption 

As we enter “the second machine age,” companies and markets contain intensive info processing—and companies are relying extra closely on IT to function successfully. This elevated use of IT has led to a big lower in inner coordination prices, permitting firms to broaden into extra native product and bodily markets. Our analysis, which analyzed administrative information from the U.S. Census Bureau, discovered that bigger companies are notably well-positioned to benefit from these economies of scale and accumulate extra organizational enhances.

The enabling and various results of IT throughout agency sizes additionally counsel IT considerably impacts market construction, contributing to the rise of commercial focus and the expansion of “celebrity companies” that may obtain a dominant market place attributable to their distinctive efficiency of their respective industries. Along with a considerably bigger impact of IT on income than its impact on employment, we additional affiliate IT with the “scale with out mass” phenomenon and the numerous decline of labor share.
