The Distinct Effects of Information Technology and Communication Technology on Firm Organization

Empirical studies on information communication technologies (ICT) typically aggregate the “information” and “communication” components together. We show theoretically and empirically that these have very different effects on the empowerment of employees, and by extension on wage inequality. If managerial hierarchies are devices to acquire and transmit knowledge and information, technologies that reduce information costs enable agents to acquire more knowledge and ‘empower’ lower level agents. Conversely, technologies reducing communication costs substitute agent’s knowledge for directions from their managers, and lead to centralization. Using an original dataset of firms in the US and seven European countries we study the impact of ICT on worker autonomy, plant manager autonomy and spans of control. Consistently with the theory we find that better information technologies (Enterprise Resource Planning for plant managers and CAD/CAM for production workers) are associated with more autonomy and a wider span of control. By contrast, communication technologies (like data networks) decrease autonomy for both workers and plant managers. Our findings are robust to using exogenous variation in cross-country telecommunication costs arising from differential regulatory regimes.

Information Technology, Organization, and Productivity in the Public Sector: Evidence from Police Departments

We examine the relationship between information technology (IT), productivity, and organization using a new panel data set of police departments that covers 1987–2003. When considered alone, increases in IT are not associated with reductions in crime rates, increases in clearance rates, or other productivity measures, and computing technology that increases reported crime actually generates the appearance of lower productivity. These results persist across various samples, specifications, and IT measures. IT investments are, however, linked to improved productivity when they are complemented with particular organizational and management practices, such as those associated with the Compstat program.

Inequality and the Organization of Knowledge

Since the seminal work of Lawrence F. Katz and Kevin M. Murphy (1992), the study of wage inequality has taken as its starting point a neoclassical constant-elasticity-of-substitution production function using as inputs capital and lowand high-skill labor. This approach assumes that the organization of production is fixed and determined by a particular specification of technology, and it ignores both the source of the interaction between workers and the organizational aspects of this interaction. These shortcomings are particularly important in light of growing empirical evidence that points, first, to the importance of decreases in the cost of processing and communicating information and, second, to the complementarity between organizational change and adjustments in the distribution of wages (e.g., Timothy F. Bresnahan et al., 2002). This paper argues that theories that seek to guide empirical research on these areas must put knowledge and information at the center of the analysis of organizations and link the organizational structure with aggregate variables via equilibrium frameworks. In Garicano and Rossi-Hansberg (2003), we present a model of this kind. It determines the patterns of organization, as manifested by the communication and specialization patterns, and the implied wage structure, that result from different costs of acquiring and communicating information. Here, we present a simple variant of this theory that allows us to focus on one of the main aspects of that framework: the sorting of agents into teams and the wage and organizational structure that accompanies that sorting. We use this simple model to analyze the changes in organization and wages that result from a very specific type of technological change: a reduction in the cost of communicating knowledge or information. This model allows us to consider the effect on within-class wage inequality, and the impact of information technology on the creation and form of organizations (e.g., size distribution of hierarchies). However, because knowledge is exogenously given, and agents cannot invest in learning, an important margin of the model in Garicano and Rossi-Hansberg (2003) is fixed, namely, the degree of “decentralization” or the extent to which problems are solved at lower levels. That model allows the simultaneous study of the acquisition of knowledge, spans of control, and matching in equilibrium. Moreover, it goes beyond the current analysis in that it allows for organizations with an unconstrained number of layers, and in that it studies two aspects of the impact of information technology: communication technology (like here) and the technology to acquire knowledge or information (e.g., processing power through cheaper database access).

Managerial Leverage is Limited by the Extent of the Market: Hierarchies, Specialization and the Utilization of Lawyers' Human Capital

This paper examines the role of hierarchies in the organization of human‐capital‐intensive production. We develop an equilibrium model of hierarchical organization and provide empirical evidence based on confidential data on thousands of law offices. The equilibrium assignment of individuals to hierarchical positions varies with the degree of field specialization, which increases as the extent of the market increases. As individuals’ knowledge becomes narrower but deeper, managerial leverage—the number of workers per manager—optimally increases to exploit this depth. Consistent with our model, the share of lawyers who work in hierarchies and the ratio of associates to partners increase as market size increases and lawyers field specialize. Other results provide evidence against alternative interpretations that emphasize unobserved differences in the distribution of demand, or firm‐size effects, and lend additional support to the view that, in legal services, hierarchies help exploit increasing returns associated with the utilization of human capital.

Knowledge, Communication, and Organizational Capabilities

This paper attempts to bridge a gap between organizational economics and strategy research through an analysis of knowledge and communication in organizations. We argue that organizations emerge to achieve the intensive use of the knowledge that is acquired to perform specific tasks and to integrate dispersed knowledge that is embodied in different human minds. The attributes of the tasks undertaken determine the optimal acquisition and distribution of knowledge. Depending on the codifiability of knowledge, different communication modes arise as a coordination mechanism to deepen the division of labor, leverage managerial talent, and exploit the increasing returns to knowledge. Organizational processes can be adapted through codes and culture to facilitate coordination; organizational structure can be designed to complement the limitations of human ability. We stress that organizational process and structure construct the core of organizational capital, which generates rent and sustains organizational growth. From the analysis, we draw implications for the strategic management of knowledge and human resources in organizations.

Intelligence Failures: An Organizational Economics Perspective

Two recent failures of the U.S. intelligence system have led to the creation of high-level investigative commissions. The failure to prevent the terrorist attacks of 9/11 prompted the creation of the National Commission on Terrorist Attacks Upon the United States (2004), or 9/11 Commission.The mistaken belief that Saddam Hussein had retained weapons of mass destruction prompted the creation of the Commission on the Intelligence Capabilities of the United States Regarding Weapons of Mass Destruction (2005), or the WMD Commission. In this paper, we use insights from organizational economics to analyze the principal organizational issues these commissions have raised in the ongoing discussion about how to prevent intelligence failures.

Completing Contracts Ex Post: How Car Manufacturers Manage Car Dealers

This article illustrates how contracts are completed ex post in practice and, in so doing, indirectly suggests what the real function of contracts may be. Our evidence comes from the contracts between automobile manufacturers and their dealers in 23 dealership networks in Spain. Franchising dominates automobile distribution because of the need to decentralize pricing and control of service decisions. It motivates local managers to undertake these activities at minimum cost for the manufacturer. However, it creates incentive conflicts, both between manufacturers and dealers and among dealers themselves, concerning the level of sales and service provided. It also holds potential for expropriation of specific investments. Contracts deal with these conflicts by restricting dealers’ decision rights and granting manufacturers extensive completion, monitoring and enforcement powers. The main mechanism that may prevent abuse of these powers is the manufacturers’ reputational capital.

Organizational Economics with Cognitive Costs

Organizational economics has advanced along two parallel tracks, one concerned with motivating agents with diverging objectives, the other--less developed--with coordinating agents under cognitive limits. This survey focuses on the second strand and attempts to bring the two strands together. Organizations are viewed as responses to the cognitive costs faced by their (potential) members. We review existing approaches such as team theory, hierarchies of processors, organizational languages and knowledge hierarchies and we argue that they can help us address an array of important organizational issues. We also review recent developments in the application of these ideas: exploiting complexity measures, combining team theory and contract theory, applying organization theories in labor economics, and using these theories to interpret the wealth of activity data that is becoming available.

The Sovereign-Bank Diabolic Loop and ESBies

We propose a simple model of the sovereign-bank diabolic loop, and establish four results. First, the diabolic loop can be avoided by restricting banks’ domestic sovereign exposures relative to their equity. Second, equity requirements can be lowered if banks only hold senior domestic sovereign debt. Third, such requirements shrink even further if banks only hold the senior tranche of an internationally diversified sovereign portfolio – known as ESBies in the euro-area context. Finally, ESBies generate more safe assets than domestic debt tranching alone; and, insofar as the diabolic loop is defused, the junior tranche generated by the securitization is itself risk-free.

Survive Another Day: Using Changes in the Composition of Investments to Measure the Cost of Credit Constraints

We introduce a novel empirical strategy to measure the size of credit shocks. Theoretically, we show that credit shocks reduce the value of long-term relative to short-term investments. Empirically, we can therefore compare the reduction of long-term relative to short-term investments within firms, allowing for firm-times-year fixed effects. Using Spanish firm-level data, we estimate the credit crunch to be equivalent to an additional tax rate of around 11% on the longest-lived capital. To pin down credit constraints as the underlying cause, we apply triple-differences strategies using foreign ownership or precrisis debt maturity.
