It is known that small firms rely mainly on the CEO’s individual knowledge for developing innovations. Recent work suggests that this approach is inefficient since it underutilizes other employees’ knowledge. We study to which extent using CEOs, managers and non-managerial employees’ ideas...

Employee resistance against innovations is a virulent phenomenon and there is a broad theoretical literature on its determinants. The empirical evidence is scarce, however, and mainly provides descriptive evidence on the incidence of the phenomenon and concentrates on the effectiveness of change...

This paper examines the management practices of German firms with obligations under the EU Emissions Trading Scheme (EU ETS) based on six structured in-depth interviews with managers of firms from different industries and based on survey data. The paper sheds light on management and trading...

Multivariate Tobit models are estimated using German cross-sectional data to test whether strategic complementarities exist between expenditures in four different types of ICT-components. If two ICT-components are complements, they are correlated (provided that agents act rationally)....

We study the effects of improvements in eBay’s rating mechanism on seller exit and continuing sellers’ behavior. Following a large sample of sellers over time, we exploit the fact that the rating mechanism was changed to reduce strategic bias in buyer rating. That improvement did not lead to...

This paper derives a three stage Cournot-oligopoly game for product innovation, expenditure on introducing the product and competition on the product market. Product innovation is assumed to increase consumer utility but is effective only if the innovating firm invests in marketing, so that...

Contractual and regulatory provisions for access affect incentives to invest in an upgraded network and, in particular, a next-generation access network. Investment decisions are made under uncertainty and have to be made over time. This papers provides a framework for taking uncertainty, risk...

What happens to demand if a magazine launches a website? This question is empirically analyzed for the German women's magazine market, a particularly large segment of the German magazine where fierce competition is reigning. Models for differentiated product demand are estimated on panel data...

This paper presents an analysis of the recent developments of average market power in Europe by using a broad firm-level database for EU member states. To indicate competitive pressure at the firm-level, markups are estimated following De Loecker (2011), and De Loecker and Warzynski (2012). The...

Contrary to previous literature we hypothesize that interests of labor may well – like that of shareholders – aim at securing the long-run survival of the firm. Consequently, employee representatives on the supervisory board could well have an interest in increasing incentive-based...
