This paper addresses the puzzle of regime-dependent volatility in foreign exchange. We extend the literature in two ways. First, our microstructural model provides a qualitatively new explanation for the puzzle. Second, we test implications of our model using Europe's recent shift to rigidly...

This paper addresses currency competition from an information perspective. Transactions in traditional models do not convey information, so transaction costs -- the driver of competition outcomes -- are driven by market size. In our model transactions do convey information (consistent with...

We propose an exchange rate model which is a hybrid of the conventional specification with monetary fundamentals and the Evans-Lyons microstructure approach. It argues that the failure of the monetary model is principally due to private preference shocks which render the demand for money...

We construct a life-cycle model in which retirement occurs at the end of life as a result of declining health. We show that improvements in life expectancy, coupled with a delay in the onset of disability, increases both the optimal consumption level and the proportion of life spent in leisure....

The introduction of the euro on 1 January 1999 created the conditions for an integrated government bond market in the euro area. Using a unique data set from the electronic trading platform Euro-MTS, we consider what is the benchmark' in this market. We develop and apply two definitions of...

We study the effects of bicycle safety regulations in both the United States and the United Kingdom on bicycle accident rates for various population age groups. We find small, statistically significant decreases in the accident rates as the stock of bicycles increases its compliance with the...

This study analyzes the effects of tobacco excise tax changes on mortality due to heart disease, cancer, and asthma. Reduced form regressions of mortality rates on tax data for the years 1954-1988, with controls for state, year, income, and unobserved persistence, indicate that tax increases...

We analyze the effects on consumers of an extreme policy experiment -- Napsterizing' pharmaceuticals -- whereby all patent rights on branded prescription drugs are eliminated for both existing and future prescription drugs without compensation to the patent holders. The question of whether this...

Observed patterns of youthful drinking indicate substantial persistence. This paper analyzes how much of that persistence reflects the actual development of a habit, and how much is due to unobserved aspects of the individual and the environment. The role of restrictions on alcohol availability,...

In 1978 North Carolina created a special fund to pay for abortions for indigent women. The appropriations for that fund have proven inadequate during five of the years in which it has been in operation, with the result in each case that no state funding was available for several months. This...
