This paper studies the impact of the network centrality of directors on the choice of payment method in mergers and acquisitions of firms in which they sit at the board. We assume that the centrality of directors reduces information asymmetry problems, facilitating information transmission...

This paper examines the price impact of trading due to expected changes in the FTSE 100 index composition. We focus on the latter index because it employs publicly-known objective criteria to determine membership and hence it provides a natural context to investigate anticipatory trading...

The level of abstention in elections has been increasing over the years in the majority of democratic countries, whether compulsory voting exists or not. We provide empirical evidence for the role of social networks as a main factor of influence in the turnout of an election. More intense social...

In the framework of incomplete markets, due to the non-existence of trade at some points in time, and using a partial equilibrium analysis, we show how the bid-ask spread of an European derivative is generated. We also find conditons for the existence of the spread. These conditions concern the...

We derive statistical arbitrage bounds for the buying and selling price of European derivatives under incomplete markets. In this paper, incompleteness is generated due to the fact that the market is dry, i.e., the underlying asset cannot be transacted at certain points in time. In particular,...

This paper studies the impact of dry markets for underlying assets on the pricing of American derivatives, using a disrete time framework. Dry markets are characterized by the possibility of non-existence of trading at certain dates. Such non-existence may be deterministic or probabilistic....

This paper presents an endogeneous model for the stochastic dynamics of the bid-ask spread of prices of nancial assets. The model is derived introducing an intermediary and inventory costs in the setting of equilibrium financial markets as described by Platen and Rebolledo (1996)

This paper analyzes the impact of illiquidity of a stock on the pricing of derivatives. In particular, it is shown how illiquidity generates a bid-ask spread in an option on this stock, even in the absence of other imperfections, such as transaction costs and asymmetry of information. Moreover,...

Part of the way venture capitalists add value to portfolio firms is by obtaining and transferring information about senior managers across firms over time. Information transfer occurs on a significant scale and takes place both among a single venture capitalist's portfolio firms and between...

Banks that supply capital and simultaneously underwrite securities for the same clients may benefit themselves or their clients at the expenses of investors by overpricing securities. We investigate this issue by analyzing price stabilization and short-term returns of IPOs. Our analysis suggests...
