Prominent scholars have complained of inadequate clarity and agreement on what transactions are, and how their costs are measured. This two-part article explores this topic and suggests an alternative approach. This part examines different meanings of transaction cost used by leading scholars in...

In the past decade, the legal and economic literature on blockchain technology and its applications has flourished. This new technology holds great promise for enhancing the efficiency of contracting. Building on the classic Coase theorem, blockchain as a decentralised mechanism of...

Zaklan (2023) examines the coasean independence property in the EU-ETS. To test this property, the author studies whether emissions are independent from the free allowance allocation. Some allowances were given for free to all EU Member States until 2012. From 2013 allowances were fully...

The Coase theorem has been shrouded in ambiguity and confusion throughout its life, this despite the prominent role that it plays in economic and legal analysis. As this paper demonstrates, this is no less true of the path by which Coase came to the result that bears his name. Drawing on...

Rapid technological diffusion has led to a heavy reliance on digital communication media, fundamentally changing how people transact and coordinate. In this paper, we study how adopting digital communication impacts allocative efficiency and welfare distributions in a Coasian bargaining...

This paper examines the evolving role played by the Coase theorem over the several editions of Richard Posner’s Economic Analysis of Law. In doing so, the paper shows both the grounding of Posner’s efficiency norm in the theorem’s logic and his increasing emphasis on the theorem’s...

This paper revisits the path by which Coase developed the result now known as the Coase theorem, including the famous meeting at the home of Aaron Director during which Coase ‘converted’ a group of Chicago economists to his way of thinking. Drawing on published and archival sources, we...

Some stories have heroes and villains. Others involve a voyage, a quest, or a monster to be defeated. The law is no exception. Broadly speaking, most legal stories are generally about identifying wrongdoers and vindicating the rights of victims, but what if harms are “reciprocal” or...

My contribution to the new volume on The Godfather and Philosophy will explore the problem of reciprocal harms in the context of the famous wedding scene in the original Godfather movie. By way of background, one of the most influential ideas in legal, moral, and political philosophy is the harm...

Ronald Coase pioneered the transaction cost approach to the modern analysis of institutions, contracts, and property rights. We argue that core theory enhances Coase’s transaction cost approach by injecting considerations of coalition formation and stability into the analysis. Analysis of...

There is a raging debate within antitrust to determine how to best assess the conduct of digital platforms and tailor the enforcement of antitrust laws to the modern economy. The distinguishing features of digital platforms can make their analysis quite different from conventional, single-sided...

From an epidemiological perspective, the COVID-19 pandemic is a public health crisis. From an economic perspective, it is an externality and a social cost. Strikingly, almost all economic policy to address the infection externality has been formulated within a Pigovian analysis of implicit taxes...

Collective action at impersonal scale involves losses to autonomy by definition because of the need to centralize some measure of authority. This stands as an important cost to collective action that varies in predictable ways depending on the extent of organizational choice available to...

This essay discusses applied price theory and how Coase Theorem could offer a market approach to the political controversy surrounding abortion restrictions. It first reviews introductory microeconomic principles of negative externalities and then discusses how Coase Theorem could be applied to...

Bigeye tuna in the Western and Central Pacific Ocean were perceived as overfished for nearly 20 years, in large part due to incidental catch in the much larger skipjack tuna fishery. Efforts to halt the overfishing of bigeye stalled due to disagreements over the distribution of costs and...

This study exploits the confiscation and auctioning off of Church property that occurred during the French Revolution to assess the role played by transaction costs in delaying the reallocation of property rights in the aftermath of fundamental institutional reform. French districts with a...

In the past decade, the legal and economic literature on blockchain technology and its applications has flourished. This new technology holds great promise for enhancing the efficiency of contracting. Building on the classic Coase theorem, blockchain as a decentralised mechanism of...

This paper investigates the performance of liability rules in two-party stochastic externality problems where negotiations are feasible and side payments are based on the realized level of externalities. Results show that an increase in polluter liability does not necessarily increase safety or...

Maintaining across-the-board restrictions is socially and economically costly, has adverse distributional impacts, and is poorly targeted in terms of protecting health and health care provision. Instead a win–win ‘Coasean’ social contract could be forged to protect older people and other...

This paper develops the empirical and theoretical case that differences in economic institutions are the fundamental cause of differences in economic development. We first document the empirical importance of institutions by focusing on two 'quasi-natural experiments' in history, the division of...

Do societies choose inefficient policies and institutions, in contrast to what would be suggested by a reasoning extending the Coase Theorem to politics? Do societies choose inefficient policies and institutions because of differences in the beliefs and ideologies of their peoples or leaders? Or...

One of the more striking features of the debate over the Coase theorem is the wide variety of models and theoretical frameworks used to discuss, evaluate, or otherwise analyze Coase’s result - an artifact of an ambiguity in Coase’s reasoning. Some framed Coase’s result in a bargaining...

Using a unique combination of datasets and estimation techniques, we test whether private lease negotiations to extract oil and natural gas exhibit features of Coasian efficiency. We demonstrate that measures of wealth (including income, house square footage, and land acreage), typically...

This paper tests the independence property under the Coase Theorem in a large multinational cap-and-trade scheme for greenhouse gas emissions, the EU Emissions Trading System (EU ETS). I analyze whether emissions of power producers regulated under the EU ETS are independent from allowance...

The present paper revisits the path by which Coase came to set down the result now generally known as the Coase theorem in his 1960 article. I draw on both the published record and archival resources in an effort to clear away some of the mist and, as it will emerge, dispel some of the...

An effective policy scheme to overcome the suboptimal low provision levels of global public goods is developed in this paper. By suggesting a decentralized approach to raise environmental public good provision levels we take account of the lack of a coercive global authority that is able to...

We reconsider the well known Becker-Coase (BC) argument, according to which changes in divorce laws should not affect divorce rates, in the context of households which consume public goods in addition to private goods. For this result to hold, utility must be transferable both within marriage...

The Coase theorem emphasizes the role transactions costs play in efficient market outcomes. We document inefficient outcomes, in the presence of a transactions cost, in southern California land markets and the corresponding transition to efficient outcomes after the transactions cost is...

We examine a setting in which property rights are initially ambiguously defined. Whether the parties go to court to remove the ambiguity or bargain and settle privately, they incur enforcement costs. When the parties bargain, a version of the Coase theorem holds. Despite the additional costs of...

This paper revisits the path by which Coase developed the result now known as the Coase theorem, including the famous meeting at the home of Aaron Director during which Coase 'converted' a group of Chicago economists to his way of thinking. Drawing on published and archival sources, we discuss...
