IT and productivity: A firm level analysis

Published on Oct 1, 2018
Abstract
Using a novel comprehensive data set of IT investment at the firm level, we find that a firm investing an additional euro in IT increases value added by 1 euro and 38 cents on average. This marginal product of IT investment increases with firm size and varies across sectors. IT explains about 10% of productivity dispersion across firms. While we find substantial returns of IT at the firm level, such returns are much lower at the aggregate level. This is due to underinvestment in IT (IT capital deepening is low) and misallocation of IT investments.

Understanding how systems of political and economic inequality evolved from relatively egalitarian origins has long been a focus of anthropological inquiry. Many hypotheses have been suggested to link socio-ecological features with the rise and spread of inequality, and empirical tests of these hypotheses in prehistoric and extant societies are increasing. In this review, we synthesize several streams of theory relevant to understanding the evolutionary origins, spread, and adaptive significance...

We develop a model of endogenous productivity change to examine the impact of the investment in knowledge on the productivity of firms. Our dynamic investment model extends the tradition of the knowledge capital model of Griliches (1979) that has remained a cornerstone of the productivity literature. Rather than constructing a stock of knowledge capital from a firm’s observed R&D expenditures, we consider productivity to be unobservable to the econometrician. Our approach accounts for uncertaint...

Although Strategy research aims to understand how firm actions have differential effects on performance, most empirical research estimates the average effects of these actions across firms. This paper promotes Random Coefficients Models (RCMs) as an ideal empirical methodology to study firm heterogeneity in Strategy research. Specifically, we highlight and illustrate three main benefits that RCMs offer to Strategy researchers — testing firm heterogeneity, predicting firm-specific effects, and es...

Learning by exporting refers to the mechanism whereby a firm's performance improves after entering export markets. This mechanism is often mentioned in policy documents, but many econometric studies have not found corroborating evidence. I show that the econometric methods rely on an assumption that productivity evolves exogenously. I show how to accommodate endogenous productivity processes such as learning by exporting. I discuss the bias introduced by ignoring such a process, and show that ad...

Many changes in the organization of work in the United States since 1975 have been attributed to the increased capabilities and use of information technology IT in business. However, few studies have attempted to empirically examine these relationships. The primary goal of this paper is to assess the hypothesis that investments in information technology are at least partially responsible for the important organizational change, the shift of economic activity to smaller firms. We examine this hyp...

Economists have shown that large and persistent differences in productivity levels across businesses are ubiquitous. This finding has shaped research agendas in a number of fields, including (but not limited to) macroeconomics, industrial organization, labor, and trade. This paper surveys and evaluates recent empirical work addressing the question of why businesses differ in their measured productivity levels. The causes are manifold, and differ depending on the particular setting. They include ...

Absorptive capacity is the principle that assimilating new knowledge requires prior knowledge. The attendant prescription is to invest more in R& D to derive greater benefit from the R& D of others (spillovers). Empirical tests of R& D productivity typically find absorptive capacity (R& D * rival R& D) to be significant. This result poses a puzzle, however: What can a firm conducting 50% of industry R& D learn from a set of firms each conducting 5%? Aren't the laggard firms merely playing catch-...

This paper examines the link between information technology (IT) and the U.S. productivity revival in the late 1990s. Industry-level data show a broad productivity resurgence that reflects both the production and the use of IT. The most IT-intensive industries experienced significantly larger productivity gains than other industries and a wide variety of econometric tests show a strong correlation between IT capital accumulation and labor productivity. To quantify the aggregate impact of IT-use ...
