We revisit the role of limited commitment in a dynamic risk-sharing setting with private information. We show that a Markov-perfect equilibrium, in which agent and insurer cannot commit beyond the current period, and an infinitely-long contract to which only the insurer can commit, implement identical consumption, effort and welfare outcomes.
We incorporate house price risk and mortgages into a standard incomplete market (SIM) model. We calibrate the model to match U.S. data and we show that the model also ac- counts for non-targeted features of the data such as the distribution of down payments, the life-cycle profile of home ownership, and the mortgage default rate.
What is the optimal policy response to a negative sectoral shock? How do frictions in goods and labor markets affect the nature and speed of the process of reallocating resources across alternative uses?
Conventional wisdom has it that inventory investment destabilizes the economy because it is procyclical to sales. Khan and Thomas (2007) show that the conventional wisdom is wrong in a general equilibrium (S,s) model with capital.
We investigate the importance of trend inflation and the real-activity gap for explaining observed inflation variation in G7 countries since 1960. Our results are based on a bivariate unobserved-components model of inflation and unemployment in which inflation is decomposed into a stochastic trend and transitory component.
With rare exception, studies of monetary policy tend to neglect the timing of innovations to monetary policy instruments. Models which take timing seriously are often difficult to compare to standard monetary VARs because each uses different frequencies.
This paper examines the inflation "pass-through" problem in American monetary policy, defined as the relationship between changes in the growth rates of individual goods and the subsequent economy-wide rate of growth of consumer prices.
In 1936-37, the Federal Reserve doubled the reserve requirements imposed on member banks. Ever since, the question of whether the doubling of reserve requirements increased reserve demand and produced a contraction of money and credit, and thereby helped to cause the recession of 1937-1938, has been a matter of controversy.
China’s average household saving rate is one of the highest in the world. One popular view attributes the high saving rate to fast rising housing prices and other costs of living in China. This article uses simple economic logic to show that rising housing prices and living costs per se cannot explain China’s high household saving rate.
This paper investigates the effectiveness of one of the Fed’s unconventional monetary policy tools, the term auction facility (TAF). At issue is whether the TAF reduced the spread between LIBOR rates and equivalent-term Treasury rates by reducing the liquidity premium embedded in LIBOR rates.
Firm-level investment is lumpy and volatile but aggregate investment is much smoother and highly serially correlated. These different patterns of investment behavior have been viewed as indicating convex adjustment costs at the aggregate level but non-convex adjustment costs at the firm level.
This paper examines the origins and early performance of the Federal Reserve as lender of last resort. The Fed was established to overcome the problems of the National Banking era, in particular an “inelastic” currency and the absence of an effective lender of last resort.
Smooth-transition autoregressive (STAR) models have proven to be worthy competitors of Markov-switching models of regime shifts, but the assumption of a time-invariant threshold level does not seem realistic and it holds back this class of models from reaching their potential usefulness.
We use a simple partial adjustment econometric framework to investigate the effects of the crisis on the dynamic properties of a number of yield spreads. We find that the crisis has caused substantial disruptions revealed by changes in the persistence of the shocks to spreads as much as by in their unconditional mean levels.
Since Galí , long-run restricted VARs have become the standard for identifying the effects of technology shocks. In a recent paper, Francis et al.  proposed an alternative to identify technology as the shock that maximizes the forecast-error variance share of labor productivity at long horizons.
To address how technological progress in financial intermediation affects the economy, a costly state verification framework is embedded into the standard growth model. The framework has two novel ingredients.
