Fracking has made America the center of global oil production and the engine of the world’s economy. But haste makes waste. America’s new oil wells are releasing natural gas as well, which is prized as a clean and reliable fuel around the world, but must be simply burned off or “flared”...

Prior to the return of democracy in 1999, the Nigerian economy was characterised by government-sponsored monopolies and subsidies in key sectors of the economy. This led to the concentration of market power in the hands of few firms. Post-1999 marked a departure from that norm and the...

With a view to reducing the consequences of corruption in public procurement, many governments have introduced debarment of suppliers found guilty of corruption and some other forms of crime. This paper explores the market effects of debarment on public procurement. Debarment is found to make...

A substantial number of cartels in the European Union are detected and enforced by the national competition authorities (NCAs). The effectiveness of domestic enforcement has been subject to extensive review and debates, which have recently culminated and resulted in the proposal for the ECN+...

Despite growing global interest in the use of algorithmic behavioural screens, big data and machine learning to detect bid rigging in procurement markets, the UK's Competition and Markets Authority (CMA) was under no obligation to undertake a project in this area, much less to publish a...

This paper finds evidence of an inverse U shape in the number of cartels detected by a Competition Agency (CA) over its lifetime. We interpret this as evidence that, as the CA builds up experience in enforcement, this feeds back into the business community to deter future cartel formation. We...

We revisit the pros and cons of cartel criminalization with focus on its possible introduction in the EU. We document a recent phenomenon that we name EU ``leniency inflation", whereby leniency has been increasingly awarded to many, and sometimes all members of a cartel. We argue that, coupled...

The May 2009 Rose Garden ceremony for President Obama’s signing of new fuel efficiency mandates for automobiles was attended by a remarkable gathering of “bootleggers and Baptists” - “Baptist” environmentalists who were pleased to get a policy they desired, and “bootlegger”...

The alleged purpose of antitrust law is to improve consumer welfare by proscribing actions and arrangements that reduce output and increase prices. Conservation seeks to improve human welfare by maximizing the long-term productive use of natural resources, a goal that often requires limiting...

Cartels are inherently instable. Each cartelist is best off if it breaks the cartel, while the remaining firms remain loyal. If firms interact only once, if products are homogenous, if firms compete in price, and if marginal cost is constant, theory even predicts that strategic interaction...
