This paper compares the output gap estimates based on a number of different methods. We take advantage of the unique properties of the Mongolian economy in order to evaluate the different approaches. We find that an economic measure derived from a Blanchard and Quah-type joint model of output...

This paper presents a new approach to evaluating multiple economic forecasts. In the past, evaluations have focused on the forecasts of individual variables. However, many macroeconomic variables are forecast at the same time and are used together to describe the state of the economy. It is,...

The relationships between the economic fluctuations of the US and China, the largest developed and developing countries respectively, are very important not only to both countries but also to the world economy. This paper applies a two-country correlated unobserved components model to explore...

This paper evaluates the potential impact of forecast errors on policy. We jointly evaluate the Federal Reserve staff forecasts of U.S. real output growth and the inflation rate in the context of the Taylor (1993) monetary policy rule. Our simple methodology generates “policy forecast...

We decompose core CPI and the food and energy CPI measures into permanent and transitory components using a correlated unobserved components model, to examine the behavior of core CPI when subject to shocks and to examine the claim that core CPI captures the persistent part of headline CPI. We...

In this paper we present a multivariate analysis of the Federal Reserve’s forecasts. First, we evaluate the Fed’s forecasts of the ten major expenditure categories of real GDP. Second, we present a new methodology for evaluating multivariate forecasts. Finally, we use the same...

This paper contributes to the debate about the relative importance of permanent versus transitory disturbances as sources of variation in output across the G-7 countries. We employ a multivariate unobserved components model to simultaneously decompose the real GDP for each of the G-7 countries...

Recent research has documented that the Federal Reserve produces systematic errors in forecasting inflation, real GDP growth, and the unemployment rate, even though these forecasts are unbiased. We show that these systematic errors reveal that the Fed is “surprised” by real and inflationary...

Recent research suggests that unobserved components models can, under certain conditions, be estimated without imposing the common zero-correlation restriction between the permanent and transitory innovations. The impact of this restriction, however, has not previously been examined in an...
