We examine the effect of a threat of entry on experimentation about demand by an incumbent monopolist when there is a fixed cost of entry. We also examine the impact of experimentation on the probability of entry into the market. We show that experimentation may itself be used as a tool for...

This paper lays down the rudiments of a descriptive theory of competition among the digital tech platforms known as “FANGs” (Facebook, Amazon, Netflix and Google), amidst rising academic and policy polarization over the answer to what seems to be – at least at the formulation level – a...

In this article I analyze strategic investment under uncertainty in a new market, where firms face a tradeoff between commitment and flexibility. The model predicts asymmetric equilibria under fairly general conditions, even though firms are ex ante identical and have symmetric opportunities to...

A parsimonious theoretical model of second degree price discrimination suggests that the business cycle will affect the degree to which firms are able to price-discriminate between different consumer types. We analyze price dispersion in the airline industry to assess how price discrimination...

The "money's worth" measure has been used to assess whether annuities are fairly valued and also as evidence for adverse selection in the annuity market. However, a regulated life assurer with concerns about predicting long-run mortality may price annuities to reduce these risks which will...

In financial markets, clients entrust their capital and data to financial infrastructure providers who are vulnerable to breaches. We develop a model in which infrastructure providers compete to provide secure and efficient client services, in the presence of a cyber-attacker. In equilibrium,...

The "quant crisis" of 2007 and subsequent unfolding of the global financial crisis highlighted the importance of the "crowded-trade" problem (not being able to know how many others are taking the same position). To investigate the crowded trading, we present a model in which informed and...

This paper examines the effect of product market threats on firms' stock crash risk. Competitive pressure from the product market aggravates managers' incentive to withhold negative information. When negative information is accumulated to a tipping point, the accumulated information all comes...

The LP formula is based upon the substitution of the exogenous risk aversion hypothesis by a credit equilibrium hypothesis. This leads to a trade-off between expected blue-sky return – the expected return excluding default scenarios – and extreme risk estimated from scenarios leading to...
