We study the multiproduct monopoly profit maximisation problem for a seller who can commit to a dynamic pricing strategy. We show that if consumers' valuations are not strongly-ordered then optimality for the seller can require intertemporal price discrimination which can be implemented by a...

Misconduct is widespread in Finance. Mis-selling, mis-representation and negligence harm consumers, or society, while raising profits. This paper presents a model of competition and misconduct in which managers are ethical. Managers must find a balance between their ethics, the actions which...

In this paper we study how bargainers impact on markets in which firms set a list price to sell to those consumers who take prices as given. The list price acts as an outside option for the bargainers, so the higher the list price, the more the firms can extract from bargainers. We find that an...

This paper considers the consumer implications of the process of convergence across multimedia and telecoms markets. Convergence starts when one firm begins to sell products in hitherto separate horizontal markets competing against rivals active in just one or other of the markets. Convergence...

This paper analyzes an alternating offer model of bargaining over the sale of an asset in a market, such as that for housing, in which another agent may come and compete for the right to strike a deal. The analysis allows the buyer and seller to have possibly differing views as to how likely...

We study the impact of AI and cryptocurrencies on consumer surplus in banking, on the price of credit, and on the price of checking accounts. We solve a competition model of banking and credit which includes client naivety, heterogeneous client risk, and imperfect risk screening. These features,...

We study the impact of ring-fencing on bank risk using short-term repo rates. Exploiting confidential data on the near-universe of sterling-denominated repo transactions, we find compelling evidence that banking groups subject to ring-fencing are perceived to be safer; repo investors lend to...

We study price competition between firms over public list or posted prices when a fraction of consumers (termed ‘bargainers') can subsequently receive discounts with some probability. Such stochastic discounts are a feature of markets in which some consumers bargain explicitly and of markets...
