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.

Is over-optimism about a country's future growth perspective good for an economy, or does over-optimism also come with costs? In this paper we provide evidence that recessions, fiscal problems, as well as Balance of Payment-difficulties are more likely to arise in countries where past growth expectations have been overly optimistic. To examine this question, we look at the medium-run effects of instances of over-optimism or caution in IMF forecasts. To isolate the causal effect of over-optimism we take an instrumental variables approach, where we exploit variation provided by the allocation of IMF Mission Chiefs across countries. As a necessary first step, we document that IMF Mission Chiefs tend to systematically differ in their individual degrees of forecast-optimism or caution. The mechanism that transforms over-optimism into a later recession seems to run through higher debt accumulation, both public and private. Our findings illustrate the potency of unjustified optimism and underline the importance of basing economic forecasts upon realistic medium-term prospects.

Economic theory offers several explanations as to why shifting expectations about future economic activity affect current demand. Abstracting from whether changes in expectations originate from swings in beliefs or fundamentals, we test empirically whether more optimistic or pessimistic potential output forecasts trigger short-term fluctuations in private consumption and investment. Relying on a dataset of actual data and forecasts for 89 countries over the 1990-2022 period, we find that private economic agents learn from different sources of in- formation about future potential output growth, and adjust their current demand accordingly over the two years following the shock in expectations. To provide a theoretical foundation to the empirical analysis, we also propose a simple Keynesian model that highlights the role of expectations about long-term output in determining short-term economic activity.

This note aims to provide guidance on the key principles and considerations underlying the design of Fund-supported programs. The note expands on the previous operational guidance notes on conditionality published over 2003-2014, incorporating lessons from the 2018-19 Review of Conditionality, and other recent key policy developments including the recommendation of the Management’s Implementation Plan in response to Independent Evaluation Office (IEO)’s report on growth and adjustment in IMF-supported programs. The note in particular highlights operational advice to (i) improve the realism of macroeconomic forecast in programs and fostering a more systematic analysis of contingency plans and risks; (ii) improve the focus, depth, implementation, and tailoring of structural conditions (SCs), with due consideration of growth effects; and (iii) help strengthen the ownership of country authorities. Designed as a comprehensive reference and primer on program design and conditionality in an accessible and transparent manner, the note refers in summary to a broad range of economic and policy considerations over the lifecycle of Fund-supported programs. As with all guidance notes, the relevant IMF Executive Board Decisions remain the primary legal authority on matters covered in this note.

Macrofinancial linkages have long been at the core of the IMF's mandate to oversee the stability of the global financial system. With the advent of the economic crisis, the Fund has drawn on this research in order to contribute to critical debates on the nature of appropriate policy responses at both the national and multilateral levels. The current juncture offers a good opportunity to take stock of this body of research by IMF staff and to share it with a wider audience, particularly since few collections have been published in this area. This volume brings together some of the best writing by IMF economists on macrofinancial issues, and highlights the issues and approaches that have guided IMF thinking in an area that makes up an increasingly important component of the IMF's overall remit. The chapters in the volume fit into three broad themes: financial crises and boom-bust cycles; financial integration, financial liberalization, and economic performance; and policy issues relating to macroeconomic policy and the corporate and financial sectors-including domestic and external financial liberalization.

This edition of the World Economic Outlook explores how a dramatic escalation of the financial crisis in September 2008 provoked an unprecedented contraction of activity and trade, despite active policy responses. It presents economic projections for 2009 and 2010, and also looks beyond the current crisis, considering factors that will shape the landscape of the global economy over the medium term, as businesses and households seek to repair the damage. The analysis also outlines the difficult policy challenges presented by the overwhelming imperative to take all steps necessary to restore financial stability and revive the global economy, and the longer-run need for national actions to be mutually supporting. The first of two analytical chapters, "What Kind of Economic Recovery?" explores the shape of the eventual recovery. The second, "The Transmission of Financial Stress from Advanced to Emerging and Developing Economies," focuses on the role of external financial linkages and financial stress in transmitting economic shocks.
