Is there a way to understand why some global environmental externalities are addressed effectively whereas others are not? The transaction costs of defining the property rights to mitigation benefits and costs is a useful framework for such analysis. This approach views international cooperation...

This article makes a contribution towards understanding the impact of temperature fluctuations on the economy and financial markets. We present a long-run risks model with temperature related natural disasters. The model simultaneously matches observed temperature and consumption growth...

In this paper, we measure the potential welfare gains from counter-cyclical policy in an economy with incomplete markets. In the course of conducting this measurement, we focus on two questions as central to the determination of those potential gains: (1) what is the likely effect of...

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...

There are many possible ways of reforming the Government-Sponsored Enterprises that insure mortgages against default, including a purely public option, complete privatization or a hybrid model with private firms and public catastrophic insurance. If the government is sufficiently capable and...

There is great uncertainty about the impact of anthropogenic carbon on future economic wellbeing. We use DSICE, a DSGE extension of the DICE2007 model of William Nordhaus, which incorporates beliefs about the uncertain economic impact of possible climate tipping events and uses empirically...

We extend the model of Fullerton, Karney, and Baylis (2012 working paper) to explore cost-effectiveness of unilateral climate policy in the presence of leakage. We ignore the welfare gain from reducing greenhouse gas emissions and focus on the welfare cost of the emissions tax or permit scheme....

This paper studies the effect of policy uncertainty on the formation of new activities in Romer's (1994) type of an economy, where productivity of labor increases with the number of capital goods. Adding a new capital good requires a capital specific set-up cost, invested prior to using the...

This paper shows that volatility induces adverse first order welfare effects in countries excluded from the global capital market. This result is illustrated in a model characterized by gains from a greater division of activities, where shocks are persistent. We show that non-linearities...

We describe two examples which illustrate in different ways how money and credit may be useful in the conduct of monetary policy. Our first example shows how monitoring money and credit can help anchor private sector expectations about inflation. Our second example shows that a monetary policy...
