We survey the theoretical and empirical literature on decentralization within firms. We first discuss how the concept of incomplete contracts shapes our views about the organization of decision-making within firms. We then overview the empirical evidence on the determinants of decentralization...

This paper describes and explains some of the principal trends in the wage and skill distribution in recent decades. There have been sharp increases in wage inequality across the OECD, beginning with the US and UK at the end of the 1970s. A good fraction of this inequality growth is due to...

We provide new evidence on the growth in pay at the very top of the wage distribution in the UK. Sectoral decompositions show that workers in the financial sector have accounted for the majority of the gains at the top over the last decade. New results are also presented on the pay of CEOs in...

It is widely believed that in the US wage growth has fallen massively behind productivity growth. Recently, it has also been suggested that the UK is starting to follow the same path. Analysts point to the much faster growth of GDP per hour than median wages. We distinguish between "net...

Scrutiny of potential mergers by the European Commission often focuses on unilateral effects or single firm dominance. But some cases have involved concerns over coordinated effects: the concern that the merger could increase the likelihood of consumer harm through tacit collusion by the reduced...

In this paper we discuss some of the most important economic issues raised in European Commission vs. Microsoft (2004) concerning the market for work group servers. In our view, the most important economic issues relate to (a) foreclosure incentives and (b) innovation effects of the proposed...

We examine trends in wage inequality in the US and other countries over the past four decades. We show that there has been a secular increase in the 90-50 wage differential in the US and the UK since the late 1970s. By contrast the 50-10 differential rose mainly in the 1980s and flattened or...

It is well known that the distribution of income in the United Kingdom has widened considerably in the last three decades. This rise has been a result of a widening at both the top and bottom of the wage distribution. More recently, most of the action appears to have occurred at the top of the...

This working paper addresses the question whether imperfect competition in product markets contributes substantially to the level and persistence of unemployment in modern industrial economies. In section I, the paper documents the available empirical research of the origin and extent of product...

We examine the "home bias" of international knowledge spillovers as measured by the speed of patent citations (i.e. knowledge spreads slowly over international boundaries). We present the first compelling econometric evidence that the geographical localization of knowledge spillovers has fallen...
