As part of the Essex Finance Centre Research Seminars at the Essex Business School, the aim of this seminar will explore the effects of market opacity and trade frictions on market efficiency and social welfare.


Seminar abstract

The aim of this paper is to examine the effects of market opacity and trade frictions, on market efficiency and social welfare in exchanges organised by centralised trade and intermediation. 

Networks are natural tools to represent the trading relationship among market participants in decentralised markets.

By constraining matching on exogenously predetermined networks and without altering the price formation mechanisms, which based on the bilateral trade limit order book technology, we compare and interpolate between highly decentralised and fully connected double auction markets.

Via laboratory experiments with human subjects we investigate

  • how the structure of the trading network affects the market reaction to public information,
  • the way asymmetric private information is aggregated into prices,
  • the manner in which the price negotiated on a particular trade reflects the relative degree of connectedness of the buyer and seller,
  • extent to which location advantages create heterogeneity in gains from trading among traders.


This is a open event. Please feel free to bring your colleagues, friends and classmates along.
