Abstract

Why do domestic stock markets in many emerging market economies fail to develop, even in the presence of high savings rates? In this paper, we argue that this may be a ‘chicken-and-egg’ problem, which we formalise as a market coordination failure. We first develop a stylised game-theoretical model, showing that when long-term equity investment is subject to network externalities, the Pareto-optimal, high-investment equilibrium is not robust to noise. Individual investors, fearing defection by others, will rationally choose a low-investment (or ‘run’) strategy, trapping the market in a state of underdevelopment. We then show how a specific institutional design – a fully-funded, individually-owned, collectively-managed, mandatory/incentivised (FICMI) pension scheme – can act as a credible coordination device and explore the welfare implications in a tractable three-period model. By providing a guaranteed, patient source of capital, FICMI changes investor expectations and makes the highinvestment, high-welfare equilibrium robust and achievable. This paper provides a new theoretical justification for funded pension systems, not as a tool to correct individual myopia, but as a public-finance institution designed to solve a collective action problem in financial market development.
