Media firms sometimes allow consumers to pay to remove advertisements from an advertisement-based product. We formally examine an ad-based monopolist's incentives to introduce this option. When deciding whether to introduce the option to pay, the monopolist compares the potential direct revenues...

This paper examines the evolution of a skew distribution of firm sizes from the viewpoit of the "Bounds" approach to market structure. It confines attention to the role played by non-strategic factors (statistical independence, and cost side eddects). A model is proposed, which leads toa...

This paper examines the evolution of a skew distribution of firm sizes from the viewpoint of the 'Bounds' approach to market structure. It confines attention to the role played by non-strategic factors (statistical independence, and cost side effects). A model is proposed, which leads to a...

Why do so many high-priced acquisitions of entrepreneurial firms take place in network industries? We develop a theory of commercialization (entry or sale) in network industries showing that high equilibrium acquisition prices are driven by the incumbents' desire to prevent rivals from acquiring...

This paper raises several issues concerning productivity analysis. An attempt is made to demonstrate the usefulness of a micro-based approach to productivity analysis which challenges some basic assumptions of conventional analyses based on aggregate production functions. With the help of a...

Multinational enterprises (MNEs) are important in transmitting technology across national borders. Not only do they allow for transfer of technology within the firm, but it is also believed that they are important channels for international R&D spillovers as well. This paper analyzes empirically...

Rapid price decreases for ICT-products in the 1990s have been largely attributed to the introduction of hedonic price indexes. Would hedonic price indexing also have large effects on measured price and productivity during other technological breakthroughs? This paper investigates the impact of...

The paper examines the determinants of the division of labor within firms. It provides an explanation of the pervasive observed changes in work organization away from the traditional functional departments and toward multi-tasking and job rotation. Whereas the existing literature on the division...

Investigating the robustness of the skill-biased technical change hypothesis, this analysis incorporates two novel features. First, effective labor is modeled as the product of a quantity measure - number of employees with a given level of education - and a quality index, depending on, i.a.,...
