"We investigate the information content of inter- transaction time and find that it varies both across stocks and over time. On average, inter-transaction time is found to be informative whenever stocks are sufficiently traded. The magnitude of the information content is found to be larger for...

This paper examines whether theoretical models of bubbles based on the notion that the price of an asset can deviate from its fundamental value are useful for understanding phenomena that are often described as bubbles, and which are distinguished by other features such as large and rapid booms...

This paper develops an equilibrium model of speculative bubbles that can be used to explore the role of various policies in either giving rise to or eliminating the possibility of asset bubbles, e.g. restricting the use of certain types of loan contracts, imposing down- payment restrictions, and...

In this paper we show that interest rate rules lead to multiple equilibria when the central bank faces a limit to its ability to print money, or when private agents are limited in the amount of bonds that can be pledged to the central bank in exchange for money. Some of the equilibria are...

This paper explores the implications of different strategies for financing the fiscal cost of twin crises for inflation and depreciation rates. We use a first-generation type model of speculative attacks which has four key features: (i) the crisis is triggered by prospective deficits, (ii) there...

This paper proposes a framework for describing why consumers use electronic banking products such as electronic bill payment, credit cards, debit cards, stored value, and e-cash. The paper surveys the literature; reports on the results of several studies, and develops a framework for evaluating...
