We present an overlapping generations model with spatial separation and agents who face liquidity risk to investigate the widely held belief that financial intermediaries exist because they save on transaction costs. We find that if agents only use a pure exchange mechanism, they engage in...

We analyze an overlapping generations economy where agents interact to share liquidity risk. We show that a pure exchange economy has excessive trade in equilibrium, and that intergenerational financial intermediaries reduce the number of interactions by catering to clienteles with uncorrelated...

We compare the call auction mechanisms of two major European stock exchanges. The French Euronext auctions disclose five levels of limit orders and have fixed ending times. The German Xetra auctions only disclose the virtual clearing price and volume, and have random ending times. For a sample...

Continuously monitored down-and-out calls and up-and-out puts have become very popular during the last decade, mainly because they can be interpreted as simple leveraged positions. Their deltas stay close to unity and their Greeks are small, particularly in low interest rate environments....

This paper analyzes market discipline in a many-bank economy where contagion and bank runs interact. We present a model with differently-informed depositors, where those depositors that are more informed have incentives to monitor banks’ investments. It is shown that when banks are...

We analyze an overlapping generations economy where agents interact to share liquidity risk. We show that a pure exchange economy has excessive trade in equilibrium because agents interact to rebalance their portfolios. Intergenerational financial intermediaries reduce the number of interactions...

This paper contributes to the literature about tax havens by providing a more comprehensive analysis of their role. The aim is to analyze how low tax jurisdictions can react to growing international pressure exerted by high tax countries to enforce compliance with anti-tax planning standards. To...

This paper presents one kind of heterogeneous strategies in some differential games where one player plays open-loop strategy and the other one plays Markovian strategy. On top of the stationary path, this kind of strategies enable the study of trajectory dynamics, even for asymmetric players’...

Saving rates and household investment in stocks and business equity are all increasing in income and wealth. Introducing subsistence consumption to a common-across-households Epstein-Zin-Weil utility function is up to a quantitative explanation, in the context of stan- dardized parsimonious...
