This paper reconsiders the developments of model evaluation in macroeconometrics over the last forty years. Our analysis starts from the failure of Cowles foundation models. The different diagnosis of this failure are then analyzed to classify them in two groups: explanations related to problems in the theoretical models that lead to problems in the identification of the relevant econometric mo...
Existing estimates of the Federal Reserve’s implicit inflation target typically rely on the assumption that it is constant for the duration of the period of analysis. This paper relaxes this assumption and estimates the implicit inflation target using a time-varying parameter model and the Kalman filter. In applying this method to the Volcker–Greenspan period, it finds significant time variatio...
We develop a theory of money and credit as competing payment instruments, then put it to work in applications. Buyers can use cash or credit, with the former (latter) subject to the inflation tax (transaction costs). Frictions making the choice of payment method interesting also imply equilibrium price dispersion, and together these deliver closed-form solutions for money demand. The model can ...
We study a simple monetary model in which a central bank faces a boundedly rational private sector and has the goal of stabilizing inflation. The system’s dynamics is generated by the interaction of the expectations about inflation of the various agents involved. A modest degree of heterogeneity in such expectations is found to have interesting consequences, in particular when the central bank ...
We examine global economic dynamics under learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. Under normal monetary and fiscal policy, the intended steady state is locally but not globally stable. Large pessimistic shocks to expectations can lead to deflationary spirals with falling prices and falling output. To avoid this outcome we recommend a...
This paper examines the impact of public information in an economy where agents also have diverse private information. Since disclosures by central banks are an important source of public information, we are able to assess how the words of central bankers shape expectations, in addition to their actions. In an otherwise standard macro model, the disproportionate role of public information degra...
We examine the role of central bank transparency when the private sector is modeled as adaptive learners. In our model, transparent policies enable the private sector to adopt correctly specified models of inflation and output while intransparent policies do not. In the former case, the private sector learns the rational expectations equilibrium while in the latter case it learns a restricted p...
This paper analyzes the relationship between money and inflation in a small open economy, where domestic and foreign currencies are perfect substitutes as means of payment. It is shown that, if the path of domestic money supply is such that individuals find it optimal to change the currency in which transactions are settled, there will be an adjustment period during which domestic inflation adj...
A dynamic spatial model is constructed where there is a role for money and for centralized payments arrangements, and where there are aggregate fluctuations driven by fluctuations in aggregate productivity. With decentralized monetary exchange and no centralized payments arrangements, there is price level indeterminacy, and the equilibrium allocation is inefficient. A private clearinghouse arra...
We present a simple menu cost model which explains the finding that firms are more likely to adjust prices upward than downward. Asymmetric adjustment to shocks arises naturally, even without trend inflation, from the desire of firms to keep industry prices as high as is sustainable and the non-convexity due to menu costs. It implies that aggregate demand shocks have asymmetric effects — negati...
