We propose an econometric model that captures the e¤ects of market microstructure on a latent price process. In particular, we allow for correlation between the measurement error and the return process and we allow the measurement error process to have a diurnal heteroskedasticity. We propose a...

We study the effects of sterilised intervention operations executed on behalf of the Swiss National Bank (SNB) using tick-by-tick transactions data between 1986 and 1995. We extend the preliminary results obtained by Fischer and Zurlinden (1991) by matching these data with intra-day indicative...

Market liquidity is typically characterized by a number of ad hoc metrics, such as depth (or market impact), volume, intermediation costs (such as breadth) etc. No general coherent denition seems to exist, and few attempts have been made to justify the existing metrics on welfare grounds. In...

This paper reviews the recent literature on game-theoretic models of market structure and their empirical implementation.

This paper uses a difference-in-difference style estimation strategy to test separately the impact of competition from public sector and private sector hospitals on the efficiency of public hospitals. Our identification strategy takes advantage of the phased introduction of a recent set of...

This paper traces the time series (?Growth of Firms?) tradition in the study of market structure and looks at how recent studies on entry and the size distribution of firms have modified thinking in this area.

We review the recent literature on market structure, firm strategies and public policy in network industries. In particular, we focus on the latest applied work, including case studies and empirical work as well as refinements of the established theoretical results. We group each set of results...

This paper reviews the recent literature on game-theoretic models of market structure and their empirical implementation.

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 sideeffects). A model is proposed, which leads to a...

This paper examines the frequency, pervasiveness, and determinants of product switching by US manufacturing firms. We find that one-half of firms alter their mix of five-digit SIC products every five years, that product switching is correlated with both firm- and firm-product attributes, and...
