Since bank deposits and currency are substitutes and banks have monopoly power, higher nominal interest rates lead to higher deposit spreads. This raises the cost of transaction services, increases bank profits and attracts entry into the banking sector. Taking these effects into account, a one...

Business cycles are costlier and stabilization policies could be more beneficial than widely thought. This paper introduces a new test to show that all business cycles are asymmetric and resemble "mini-disasters." By this we mean that growth is pervasively fat-tailed and non-Gaussian. Using...

A representative-consumer model with Epstein-Zin-Weil preferences and i.i.d. shocks, including rare disasters, accords with key asset-pricing observations. If the coefficient of relative risk aversion equals 3-4, the model accords with observed equity premia and risk-free real interest rates. If...

Governments are known for procrastinating when it comes to resolving painful policy problems. Whatever the political motives for waiting to decide, procrastination distorts economic decisions relative to what would arise with early policy resolution. In so doing, it engenders excess burden. This...

At a minimum, this paper should serve as a warning against too easy an acceptance of the view that the costs of sustained inflation are small relative to the costs of unemployment. If a temporary reduction in unemployment causes a permanent increase in inflation, the present value of the...

This paper sets out alternatives to the traditional model of labour supply used to analyse the welfare costs of income and/or sales taxes when preferences are defined over goods and leisure and the market wage yields the slope of the budget constraint. The innovation in our work is to assume...

Infectious disease is currently the main cause of mortality in the world and has been even more important historically. This paper reviews recent research in economic epidemiology. Specifically, it discusses the occurrence of infectious diseases and the effects of public health interventions...

How far can shoe-leather go in explaining the welfare cost of inflation? Using a unique set of microeconomic data on households, we estimate the parameters of the demand for money derived from the generalized Baumol-Tobin model. Our data set contains information on average holdings of cash, on...

Recent literature has highlighted the importance of new activities in development and growth. It was shown that trade distortions such as tariffs are associated with first-order costs stemming from the induced drop in the formation of new activities. This paper demonstrates that uncertainty may...

We construct a simple model in which high inflation imposes welfare costs because it affects the ability of the financial sector to screen between high and low cost producers. Consumers search for a low price and inflation reduces the incentives to search, resulting in an increase in the demand...
