How Accurate Are Private Sector Forecasts--Cross-Country Evidence from Consensus Forecasts of Output Growth


Book Description

How well does the private sector forecast output growth? This paper provides evidence on this question using data from the publication Consensus Forecasts. The evidence is useful for a number of reasons. First, many industrialized countries are in the midst of long expansions, and the question of when these expansions will come to an end is being debated. Many private forecasters have issued rosy predictions for growth in the major industrialized countries and for several developing countries as well. Can these predictions be trusted? How good are forecasters at predicting recessions? Second, private sector capital flows have supplanted official funds as the dominant form of external financing for many countries. Hence, private sector assessments of the relative macroeconomic outlook for various countries play a role in guiding the allocation of capital across the globe.




Information Rigidities in Economic Growth Forecasts


Book Description

We examine the behavior of forecasts for real GDP growth using a large panel of individual forecasts from 30 advanced and emerging economies during 1989–2010. Our main findings are as follows. First, our evidence does not support the validity of the sticky information model (Mankiw and Reis, 2002) for describing the dynamics of professional growth forecasts. Instead, the empirical evidence is more in line with implications of "noisy" information models (Woodford, 2002; Sims, 2003). Second, we find that information rigidities are more pronounced in emerging economies than advanced economies. Third, there is evidence of nonlinearities in forecast smoothing. It is less pronounced in the tails of the distribution of individual forecast revisions than in the central part of the distribution.




Macrofinancial Causes of Optimism in Growth Forecasts


Book Description

We analyze the causes of the apparent bias towards optimism in growth forecasts underpinning the design of IMF-supported programs, which has been documented in the literature. We find that financial variables observable to forecasters are strong predictors of growth forecast errors. The greater the expansion of the credit-to-GDP gap in the years preceding a program, the greater its over-optimism about growth over the next two years. This result is strongest among forecasts that were most optimistic, where errors are also increasing in the economy’s degree of liability dollarization. We find that the inefficient use of financial information applies to growth forecasts more broadly, including the IMF’s forecasts in the World Economic Outlook and those produced by professional forecasters compiled by Consensus Economics. We conclude that improved macrofinancial analysis represents a promising avenue for reducing over-optimism in growth forecasts.




How Well Do Economists Forecast Recessions?


Book Description

We describe the evolution of forecasts in the run-up to recessions. The GDP forecasts cover 63 countries for the years 1992 to 2014. The main finding is that, while forecasters are generally aware that recession years will be different from other years, they miss the magnitude of the recession by a wide margin until the year is almost over. Forecasts during non-recession years are revised slowly; in recession years, the pace of revision picks up but not sufficiently to avoid large forecast errors. Our second finding is that forecasts of the private sector and the official sector are virtually identical; thus, both are equally good at missing recessions. Strong booms are also missed, providing suggestive evidence for Nordhaus’ (1987) view that behavioral factors—the reluctance to absorb either good or bad news—play a role in the evolution of forecasts.




IMF Staff Papers, Volume 49, No. 1


Book Description

This paper presents details of a symposium on forecasting performance I organized under the auspices of the IMF Staff Papers. The assumption that the forecaster's goal is to do as well as possible in predicting the actual outcome is sometimes questionable. ln the context of private sector forecasts, this is because the incentives for forecasters may induce them to herd rather than to reveal their true forecasts. Public sector forecasts may also be distorted, although for different reasons. Forecasts associated with IMF programs, for example, are often the result of negotiations between the IMF staff and the country authorities and are perhaps more accurately viewed as goals, or targets, rather than pure forecasts. The standard theory of time series forecasting involves a variety of components including the choice of an information set, the choice of a cost function, and the evaluation of forecasts in terms of the average costs of the forecast errors. It is generally acknowledged that by including more relevant information in the information set, one should be able to produce better forecasts.




Reality Check


Book Description

The Middle East and North Africa economies face an uncertain recovery. The war in Ukraine presents significant challenges to the global economy and the MENA region. Inflationary pressures brought about by the pandemic are likely to be further exacerbated by the conflict. The potential for rising food prices is even higher, which is likely to hurt the wallets of the poor and vulnerable in the region. The COVID-19 pandemic continues to cast a shadow. As the latest variant sweeps over the region, countries grapple with a host of problems depending on initial conditions and policy priorities. The region, like the rest of the world, is not out of the woods yet. Vaccinations remain the effective path out of the pandemic, leading to lower hospitalizations and death rates. Testing helps curb the spread. During times of uncertainty, it is important to not be overconfident about the region’s growth prospects. Growth forecasts serve as a significant signpost for policymakers to chart a path forward. Over the last decade, growth forecasts in the MENA region have often been inaccurate and overly optimistic, which can lead to economic contractions down the road due to ebullient borrowing. There is considerable room for the region to improve its forecasts that are largely hindered by opaque data systems, growth volatility and conflict. The MENA region lags considerably in the timely production of credible statistics. A key finding of the report is that the best way to improve forecasters is to provide forecasters with as much good quality information as possible.




Forecasting


Book Description

Concise, engaging, and highly intuitive--this accessible guide equips you with an understanding of all the basic principles of forecasting Making accurate predictions about the economy has always been difficult, as F. A. Hayek noted when accepting his Nobel Prize in economics, but today forecasters have to contend with increasing complexity and unpredictable feedback loops. In this accessible and engaging guide, David Hendry, Michael Clements, and Jennifer Castle provide a concise and highly intuitive overview of the process and problems of forecasting. They explain forecasting concepts including how to evaluate forecasts, how to respond to forecast failures, and the challenges of forecasting accurately in a rapidly changing world. Topics covered include: What is a forecast? How are forecasts judged? And how can forecast failure be avoided? Concepts are illustrated using real-world examples including financial crises, the uncertainty of Brexit, and the Federal Reserve's record on forecasting. This is an ideal introduction for university students studying forecasting, practitioners new to the field and for general readers interested in how economists forecast.

World Economic Outlook, October 2013


Book Description

Global growth is in low gear, and the drivers of activity are changing. These dynamics raise new policy challenges. Advanced economies are growing again but must continue financial sector repair, pursue fiscal consolidation, and spur job growth. Emerging market economies face the dual challenges of slowing growth and tighter global financial conditions. This issue of the World Economic Outlook examines the potential spillovers from these transitions and the appropriate policy responses. Chapter 3 explores how output comovements are influenced by policy and financial shocks, growth surprises, and other linkages. Chapter 4 assesses why certain emerging market economies were able to avoid the classical boom-and-bust cycle in the face of volatile capital flows during the global financial crisis.




The New American Economy


Book Description

As a domestic policy advisor to Ronald Reagan, Bruce Bartlett was one of the originators of Reaganomics, the supply-side economic theory that conservatives have clung to for decades. In The New American Economy, Bartlett goes back to the economic roots that made Impostor a bestseller and abandons the conservative dogma in favor of a policy strongly based on what's worked in the past. Marshalling compelling history and economics, he explains how economic theories that may be perfectly valid at one moment in time under one set of circumstances tend to lose validity over time because they are misapplied under different circumstances. Bartlett makes a compelling, historically-based case for large tax increases, once anathema to him and his economic allies. In The New American Economy, Bartlett seeks to clarify a compelling and way forward for the American economy.
