This note raises the IMF’s profile on a number of issues related to inequality, unemployment, governance, etc. It builds on earlier empirical work that examined correlations between growth downbreaks/duration of growth spells and a range of macro/policy/institutional factors. This paper is designed to be more accessible, more policy oriented, and focused squarely on the issue of inequality and the sustainability of growth. It will reference the literature that has gained prominence in the wake of the global crisis, and the possible links between the crisis and rising inequality in countries at the epicenter of the crisis. The analytical findings will also be connected to real world policy narratives in certain countries, to provide texture to the results and enhance policy relevance. The paper will argue that, based on the empirical findings, more equality in the income distribution is associated with longer-lived growth spells. Broad redistributive policies are not necessarily pro-growth, however, as these can have strong disincentive effects. The paper’s policy discussion is appropriately cautious, therefore, offering only tentative ideas, for example, active labor market policies and more attention to human capital investments designed to avoid conflicts between efficiency and equity perspectives.

Two Sides of the Same Coin?

Inequality and Unsustainable Growth

Many low-income countries continue to describe their monetary policy framework in terms of targets on monetary aggregates. This contrasts with most modern discussions of monetary policy, and with most practice. We extend the new-Keynesian model to provide a role for “M” in the conduct of monetary policy, and examine the conditions under which some adherence to money targets is optimal. In the spirit of Poole (1970), this role is based on the incompleteness of information available to the central bank, a pervasive issues in these countries. Ex-ante announcements/forecasts for money growth are consistent with a Taylor rule for the relevant short-term interest rate. Ex-post, the policy maker must choose his relative adherence to interest rate and money growth targets. Drawing on the method in Svensson and Woodford (2004), we show that the optimal adherence to ex-ante targets is equivalent to a signal extraction problem where the central bank uses the money market information to update its estimate of the state of the economy. We estimate the model, using Bayesian methods, for Tanzania, Uganda (both de jure money targeters), and Ghana (a de jure inflation targeter), and compare the de facto adherence to targets with the optimal use of money market information in each country.

On the Optimal Adherence to Money Targets in a New-Keynesian Framework

This paper evaluates three models for predicting currency crises that were proposed before 1997. The idea is to answer the question: if we had been using these models in late 1996, how well armed would we have been to predict the Asian crisis? The results are mixed but somewhat encouraging. One model, and our modifications to it, provide useful forecasts, at least compared with a naive benchmark. The head-to-head comparison also sheds light on the economics of currency crises, the nature of the Asian crisis, and issues in the empirical modeling of currency crises.

We develop a DSGE model with a banking sector to analyze the impact of the financial crisis on Zambia and the role of the monetary policy response. We view the crisis as a combination of three related shocks: a worsening in the terms of the trade, an increase in the country’s risk premium, and a decrease in the risk appetite of local banks. We characterize monetary policy as "stop and go": initially tight, subsequently loose. Simulations of the model broadly match the path of the economy during this period. We find that the initial policy response contributed to the domestic impact of the crisis by further tightening financial conditions. We study the factors driving the "stop" part of policy and derive policy implications for central banks in low-income countries.

VAR methods suggest that the monetary transmission mechanism may be weak and unreliable in low-income countries (LICs). But are structural VARs identified via short-run restrictions capable of detecting a transmission mechanism when one exists, under research conditions typical of these countries? Using small DSGEs as data-generating processes, we assess the impact on VAR-based inference of short data samples, measurement error, high-frequency supply shocks, and other features of the LIC environment. The impact of these features on finite-sample bias appears to be relatively modest when identification is valid—a strong caveat, especially in LICs. However, many of these features undermine the precision of estimated impulse responses to monetary policy shocks, and cumulatively they suggest that “insignificant” results can be expected even when the underlying transmission mechanism is strong.

Uncovering the Monetary Transmission Mechanism in Low-Income Countries

VAR meets DSGE

The Fund has recognized in recent years that one cannot separate issues of economic growth and stability on one hand and equality on the other. Indeed, there is a strong case for considering inequality and an inability to sustain economic growth as two sides of the same coin. Central to the Fund’s mandate is providing advice that will enable members’ economies to grow on a sustained basis. But the Fund has rightly been cautious about recommending the use of redistributive policies given that such policies may themselves undercut economic efficiency and the prospects for sustained growth (the so-called “leaky bucket” hypothesis written about by the famous Yale economist Arthur Okun in the 1970s). This SDN follows up the previous SDN on inequality and growth by focusing on the role of redistribution. It finds that, from the perspective of the best available macroeconomic data, there is not a lot of evidence that redistribution has in fact undercut economic growth (except in extreme cases). One should be careful not to assume therefore—as Okun and others have—that there is a big tradeoff between redistribution and growth. The best available macroeconomic data do not support such a conclusion.
