We show that a market involving a handful of large-scale firms and a myriad of small-scale firms may give rise to different types of market structure, ranging from monopoly or oligopoly to monopolistic competition through new types of market structure. In particular, we find conditions under...

The declining labor share in national income and rising inequality over the last four decades raise questions about causes of these trends. In order to explain these trends, we develop a theoretical model that links intra-industry distribution of wages to variation in market power of firms. The...

We investigate the sources, scope, and implications of landowner market power. We show how zoning regulations generate spillovers through increased markups and derive conditions under which restricting landownership concentration reduces rents. Using newbuilding-level data from New York City, we...

The effects of competition on growth are analyzed in the recent literature by comparing economies with the same market structure but different degrees of substitutability. In this note, we show that in a general equilibrium model with monopolistic competition – la Dixit- Stiglitz the effect of...

Competition among health insurers is widely considered to be a means of enhancing efficiency and containing costs in the health care system. In this paper, it is argued that this could be unsuccessful since health care providers hold a strong position on the market for health care services....

We develop a structural framework that allows us to quantify the evolution of aggregate bilateral trade costs and markups over time. With minimal assumptions, we can disentangle aggregate markup and trade cost changes from observed changes in trade flows. We apply our method to trade data...

This paper makes use of evolutionary, institutional and behavioural economics to develop a theory of the non-survival of dominant socioeconomic organisations with market power – the failure of monopolies. Using New Institutional Economics we demonstrate the necessity of hierarchy in massive...

Persistent shifts in equilibria are likely to arise in oligopolistic markets and may be detrimental to the measurement of conduct, related markups and intensity of competition. We develop a cointegrated VAR (vector autoregression) based approach to detect long-run changes in conduct when data...

The prevalence of third-party tracking in our modern ecosystem cannot be ignored. Trackers, on our websites and apps, enable multi-sourced data gathering, at distinct volume, velocity, verity and veracity. While employed by numerous operators, the majority of these trackers are controlled by a...
