Forecasts guide decisions in all areas of economics and finance. Economic policy makers base their decisions on business cycle forecasts, investment decisions of firms are based on demand forecasts, and portfolio managers try to outperform the market based on financial market forecasts. Forecasts extract relevant information from the past and help to reduce the inherent uncertainty of the future. The topic of this special issue of the Journal of Economics and Statistics is the theory and practise of forecasting and forecast evaluation and an overview of the state of the art of forecasting.

In this valuable volume, Nobel Prize-winner Klein gathers together a group of authors who focus on forecasting models for a number of economies. The variety of the models and the structural differences among them are especially interesting. . . Readers interested in forecasting methodologies will find much of value in this volume. Highly recommended. I. Walter, Choice This important book, prepared under the direction of Nobel Laureate Lawrence R. Klein, shows how economic forecasts are made. It explains how modern developments in information technology have made it possible to forecast frequently at least monthly but also weekly or bi-weekly depending upon the perceived needs of potential forecast users and also on the availability of updated material. The book focuses on forecasts in a diverse range of economies including the United States, China, India, Russia, Germany, Japan, South Korea, and Turkey. At a time of great economic uncertainty, this book makes an important contribution by showing how new information technology can be used to prepare national economic forecasts.

The latest World Economic Outlook reports signs that policy tightening is starting to cool activity despite core inflation proving persistent. Risks are more balanced as banking sector stress has receded, but they remain tilted to the downside. Monetary policy should stay the course to bring inflation to target, while fiscal consolidation is needed to tackle soaring debts. Structural reforms are crucial to revive medium-term growth prospects amid constrained policy space.

Assessing the current state of the economy and forecast the economic outlook in the next few quarters are important inputs for policymakers. This paper presents a suite of models with an integrated approach to forecast Cambodia’s economy in the current and next few quarters. First, we estimate historical quarterly GDP using information extracted from high-frequency indicators to construct quarterly nowcasting model. Second, we forecast current economic activities using a high-frequency data such as credit, export, tourist arrival, foreign reserves, and trading partner’s GDP. Third, we present inflation forecasting models for Cambodia. Fourth, the paper present a vector autoregression model to forecast Cambodia’s GDP in the next few quarters using global forecasts of China’s and US’s economy as well as oil and rice price. This paper showcase how high-frequency data set can be utilized in assessing current economic activities in countries with limited and lagged data.

With the global economy gaining some momentum, economies of Latin America and the Caribbean are recovering from a recession at the regional level in 2016. This gradual improvement can be understood as tale of two adjustments, external and fiscal, that are ongoing in response to earlier shocks. But headwinds from commodity terms-of-trade shocks and country-specific domestic factors are fading, paving the way for real GDP to grow by about 1 percent in 2017. Regional activity is expected to pick up further momentum in 2018, but at a slower pace than previously anticipated, while medium-term growth is projected to remain modest at about 2.6 percent. The outlook is shaped by key shifts in the global economic and policy landscape—where slow growth, low productivity, and high income inequality are creating pressure for a shift toward inward- looking policies in some advanced economies. Domestic fundamentals and developments, however, will continue to play a significant role in determining growth for the region. At the same time, risks to the outlook have widened in a setting of higher global uncertainty. In this challenging external context, countries should aim for completing fiscal and external adjustments to preserve or rebuild policy buffers. Charting a course toward higher, sustainable, and more equitable growth will also require strengthening structural reforms. Specifically, closing infrastructure gaps, improving the business environment, governance, and education outcomes, and encouraging female labor participation are necessary to boost medium-term growth and foster income convergence. Chapters in this report examine the ongoing external adjustment to terms-of-trade shifts, drivers of capital flows to the region, the role of the investor base, and macroeconomic impact of migration and remittances.

The World Economic Outlook, published twice a year in English, French, Spanish, and Arabic, presents IMF staff economists analyses of global economic developments during the near and medium term. Chapters give an overview of the world economy; consider issues affecting industrial countries, developing countries, and economies in transition to market; and address topics of pressing current interest. Annexes, boxes, charts, and an extensive statistical appendix augment the text.
