We study the role of privacy in the market for mobile applications. For such programs used with smartphones and tablet PCs a very important market has emerged. Yet, neither the role of privacy on that market is well understood, nor do we have empirical evidence regarding its role therein. We...

We shed light on a money-for-privacy trade-off in the market for smartphone applications ("apps"). Developers offer their apps cheaper in return for greater access to personal information, and consumers choose between lower prices and more privacy. We provide evidence for this pattern using data...

We analyze the data collection strategies of 65,000 developers in the market for mobile applications and track 300,000 applications over four years. Many apps belong to developers with multiple apps. This fact generates variation in the privacy behaviors of the same developer for our analysis....

Using a unique German firm-level data set, we provide empirical evidence for a productivity sorting along two dimensions: international activity and technology choice. We consider domestic and exporting firms and measure technology choice by firms' actual use of advanced information technology...

The missing effect of investments of firms in information and communication technologies on productivity is studied by various recent papers (e.g. Oliner and Sichels 1994, Landauer 1995, Brynjolfsson and Hitt 1996). Several explanations are given for this missing link. Our paper deals with two...

This paper analyses the link between the high-skilled employment share and the level of investment in information technology (IT) in the service production process. The analysis is based on an unbalanced panel data set for 933 West German firms over the period 1994-1996. To account for firms...

This paper examines whether information technology (IT) and decentralized work organization are complementary only for large firms or also for smaller firms. Empirical evidence, which suggests complementarity between IT and decentralization, is mainly based on large firms. Using data from a...

Firm heterogeneity explains the productivity driven selection mechanism that determines aggregate productivity growth within industries. This paper empirically demonstrates that ICT has a robust impact on firm heterogeneity only when ICT is used intensively and jointly with specific ICT...

This paper analyzes the impact of the decision to contract ICT consulting on firms' innovative incentives. The paper develops a theoretical model and estimates some of its implications for a sample of German firms. In particular, the paper estimates the average treatment effect of the decision...

The paper provides empirical evidence for the question whether firms' ITenabled labour productivity is affected by the age structure of the workforce. We apply a production function approach with heterogenous labour to firmlevel data from German manufacturing and services industries. We find...
