Book Description
The study applies a BEKK GARCH-M model to examine the effect of uncertainty on the levels of inflation and output growth in Nigeria. The results suggest a significant positive effect of inflation uncertainty on the level of inflation, supporting the Cukierman and Meltzer (1986) hypothesis. In addition, uncertainty about inflation is found to be detrimental to output growth, supporting the Friedman’s (1977) hypothesis of a negative effect of inflation uncertainty on output growth. Uncertainty about growth does not have a significant effect on both the levels of inflation and output growth. The evidence in this study suggests that Nigeria should put in place policies minimizing inflation uncertainty to avoid its adverse effects on the economy. In addition, the independence relationship between output growth and its uncertainty in Nigeria suggest that they can be treated separately as suggested by business cycle models.

Book Description
The aim of this paper is to analyse the dynamics relationships between inflation, output growth, and real and nominal uncertainty using the VARFIMA-BEKK MGARCH model of inflation and output growth and quarterly data for the UK covering the 1957:Q2-2006:Q4 period. The analysis is also done for the three sub-periods determined by considering the structural changes such as the Great Moderation in the series of the UK. Two findings are obtained. First, the evidence obtained from the full period supports a number of important conclusions, one of which is mixed evidence regarding the effect of inflation on inflation uncertainty, another one being strong evidence regarding the positive effect of inflation uncertainty on inflation and output growth. Taking this into account, it is possible to put forward that an essential determinant of economic growth is uncertainty about the inflation rate. The last finding for this period is that output growth uncertainty is a positive determinant of the inflation and output growth rate. Second, the evidence found from the sub-periods is that there are no linkages between inflation, output growth and their volatility.

Book Description
We use a bivariate generalized autoregressive conditionally heteroskedastic (GARCH) model of inflation and output growth to examine the causality relationship among nominal uncertainty, real uncertainty and macroeconomic performance measured by the inflation and output growth rates. The application of the constant conditional correlation GARCH(1,1) model leads to a number of interesting conclusions. First, inflation does cause negative welfare effects, both directly and indirectly, i.e. via the inflation uncertainty channel. Secondly, in some countries, more inflation uncertainty provides an incentive to Central Banks to surprise the public by raising inflation unexpectedly. Thirdly, in contrast to the assumptions of some macroeconomic models, business cycle variability and the rate of economic growth are related. More variability in the business cycle leads to more output growth.

Book Description
Output gap estimates are subject to a wide range of uncertainty owing to data revisions and the difficulty in distinguishing between cycle and trend in real time. This is important given the central role in monetary policy of assessments of economic activity relative to capacity. We show that country desks tend to overestimate economic slack, especially during recessions, and that uncertainty in initial output gap estimates persists several years. Only a small share of output gap revisions is predictable ex ante based on characteristics like output dynamics, data quality, and policy frameworks. We also show that for a group of Latin American inflation targeters the prescriptions from typical monetary policy rules are subject to large changes due to output gap revisions. These revisions explain a sizable proportion of the deviation of inflation from target, suggesting this information is not accounted for in real-time policy decisions.
