This paper develops a model that speaks to the goals and methods of financial-stability policies. There are three main points. First, from a normative perspective, the model defines the fundamental market failure to be addressed, namely that unregulated private money creation can lead to an...

In this paper we consider a two-country New Open Economy Macroeconomics model, and analyze the optimal monetary policy when countries cooperate in the face of a "global liquidity trap" - i.e., a situation where the two countries are simultaneously caught in liquidity traps. Compared to the...

Aging populations in advanced economies are placing ever-increasing demands on government spending in the form of old-age benefits. Economies that have promised substantially more benefits than they have made provision to finance are heading into a prolonged era of fiscal stress. Unresolved...

The last 15 years has brought forth an explosion of research on consumption-based asset pricing as a leading contender for explaining aggregate stock market behavior. This research has propelled further interest in consumption-based asset pricing, as well as some debate. This chapter surveys the...

Many advanced economies are heading into an era of fiscal stress: populations are aging and governments have made substantially more promises of old-age benefits than they have made provisions to finance. This paper models the era of fiscal stress as stemming from relentlessly growing promised...

In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a two-sector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with...

Prevalent thinking about liquidity traps suggests that the perfect substitutability of money and bonds at a zero short-term nominal interest rate renders open-market operations ineffective for achieving macroeconomic stabilization goals. In an earlier paper, we showed that this reasoning does...

When excess returns are used to estimate linear stochastic discount factor (SDF) models, researchers often adopt a normalization of the SDF that sets its mean to 1, or one that sets its intercept to 1. These normalizations are often treated as equivalent, but they are subtly different both in...

We present a model in which some investors are prohibited from using leverage and other investors' leverage is limited by margin requirements. The former investors bid up high-beta assets while the latter agents trade to profit from this, but must de-lever when they hit their margin constraints....
