Information flows are necessary for well-functioning financial markets. However, in many emerging markets, the legal and institutional preconditions for proper information flow are not met. How do such markets respond? We argue that they respond by developing innovative information transmission mechanisms. We identify one such mechanism associated with the evolution of equity markets in South Asia. The mechanism operates through a financing instrument unique to India and Pakistan, called badla in local parlance. We develop a signaling model in which a broker-financier signals his private information to investors by choosing various levels of financing to provide in the badla market for stocks. A fully separating equilibrium exists allowing full discrimination of various types of stocks. Hence, information transmission takes place through this channel.
