Brief: Cannibalisation

Cannibalisation occurs when a company reduces the sales of one of its products by introducing a similar, competing product in the same market. Igami and Yang study this phenomenon in relation to burger outlets, pointing out that entry of new outlets harms the profitability of existing stores (cannibalisation) but that this occurs so as to Read more about Brief: Cannibalisation[…]

Strategic Pricing

This article will explore an overview of pricing strategy. We begin by explaining the simple Cournot and Bertrand games, which are game theoretic analyses of a firm’s pricing strategy. With this information we proceed by explaining what strategic complementarities and substitutes are before looking at a paper by Fudenberg and Tirole entitled “The Fat-Cat Effect, Read more about Strategic Pricing[…]

Standards of Living during the Industrial Revolution

The debate about living standards in the Industrial Revolution has recently focused on anthropometric measures, such as height and mortality, and linked these to the ability to work more intensively.

To what extent can these aspects of interwar unemployment be attributed to this supply-side change? Read more about Unemployment during the Inter-War period[…]

A letter to my children
