Abstract
This paper uses a multi-methodological approach to measure the fiscal costs of monetary and exchange rate policy distortions in Zimbabwe. It identifies three channels through which these policy distortions affect tax revenue: the Olivera-Tanzi Effect (inflation-related tax payment lags), an overvalued official exchange rate affecting customs duty on imports, and informalization undermining overall revenue collection. It then measures the fiscal costs of each of these three channels. The paper shows that although inflation tax increases government revenue through seigniorage, its negative impact on tax revenue outweighs its benefit. High inflation and exchange rate distortions have costed Zimbabwe Treasury over three billion US dollars between 2020 and 2023. Policies that remove exchange rate distortions and stabilize prices can substantially improve government revenue and help close the fiscal financing gap.

Publication The Real Exchange Rate and Economic Growth(World Bank, Washington, DC, 2008)The real exchange rate was not at the center of the first generation of neoclassical growth models, nor was it prominent among the policy prescriptions that flowed from those models. Recent analyses, in contrast, have paid it more attention. This paper analyzes the role of the real exchange rate in the growth process, the channels through which the real exchange rate influences other variables, and policies useful (and not useful) for governing the real rate. An appendix provides econometric evidence supportive of the emphases in the text.Publication Can Real Exchange Rate Undervaluation Boost Exports and Growth in Developing Countries? Yes, But Not for Long(World Bank, Washington, DC, 2010-06)A policy of managed real undervaluation may have been an important factor behind the success of East Asia's export-led growth model. But current discussions over the value of China's currency demonstrate the controversy this kind of policy can generate. Although a managed real undervaluation can enhance domestic competitiveness, it is difficult to sustain both economically and politically in the post-crisis environment. The authors show that a real undervaluation works only for low-income countries, and only in the medium term.Publication Intertemporal Adjustment and Fiscal Policy Under a Fixed Exchange Rate Regime(World Bank, Washington, DC, 2008-04)The paper presents a dynamic model for small to medium open economies operating under a fixed exchange rate regime. The model provides a partial explanation of the channels through which fiscal and monetary policy affects the real exchange rate. An empirical investigation is conducted for the case of Argentina during the currency board period of 1991-2001. Empirical estimates show that fiscal policy may indeed be an efficient instrument for promoting macroeconomic stability insofar as it encourages convergence toward long-run equilibrium and alters the long-term balance between exports and consumption, both private and public. The simulation applied to Argentina shows that if the share of public spending in the economy is higher than the share of imports, an increase in the tax rate will stimulate capital stock slightly, at least in the short term, and depreciate the real effective exchange rate. In the long run, the fiscal policy affects the value of the real exchange rate and consequently external competitiveness.Publication Exchange Rate Overvaluation and Trade Protection(World Bank, Washington, DC, 2000-02)Despite a trend toward more flexible rates, more than half the world's countries maintain fixed or managed exchange rates. In the 1980s and 1990s, developing countries as a group progressively liberalized their trade regimes, but some governments defend their exchange rate in actions that run counter to long-run plans for liberalization. Without discussing the relative merits of fixed and flexible exchange rate systems, the authors note that exchange rate management in many countries has resulted in overvaluation of the real exchange rate. Roughly twenty five percent of the countries for which data are available have overvalued exchange rates, with black market premiums from 10 percent to more than 100 percent. After surveying the literature, the authors present lessons from experience about what has worked (or not) in response to crises involving external shocks and external trade deficits - and why. Trying to defend an overvalued exchange rate with protectionist trade policies is a classic pattern, but experience shows such protection does significantly retard the country's growth, and delay its integration into the world trading community. In fact, and overvalued exchange rate is often the root cause of protection, preventing the country from returning to more liberal trade policies that allow growth and integration into the world community without exchange rate adjustment. Most developing countries have downward price and wage rigidities and, with an external trade deficit, require some form of nominal exchange rate adjustment to restore external equilibrium. The authors present cross-country econometric and case study evidence - citing examples from Argentina, Chile, Ghana, the Republic of Korea, Malaysia, Turkey, Uruguay, and Sub-Saharan Africa (including the CFA zone) - that overvalued exchange rates reduce economic growth. Defending the exchange rate, they show, has nor no medium-term benefits, since falling reserves will eventually force devaluation. Better to have devaluation occur without further debilitating losses in reserves and lost productivity because of import controls. After devaluation the exchange rate will reach a new equilibrium, strongly influenced by government and central bank policies.Publication Analyzing the Distributional Impact of Reforms : A Practioner's Guide to Trade, Monetary and Exchange Rate Policy, Utility Provision, Agricultural Markets, Land Policy and Education, Volume 1(Washington, DC: World Bank, 2005)The analysis of the distributional impact of policy reforms on the well-being or welfare of different stakeholder groups, particularly on the poor and vulnerable, has an important role in the elaboration and implementation of poverty reduction strategies in developing countries. In recent years this type of work has been labeled as Poverty and Social Impact Analysis (PSIA) and is increasingly implemented to promote evidence-based policy choices and foster debate on policy reform options.

Publication Supporting Youth at Risk(World Bank, Washington, DC, 2008)The World Bank has produced this policy Toolkit in response to a growing demand from our government clients and partners for advice on how to create and implement effective policies for at-risk youth. The author has highlighted 22 policies (six core policies, nine promising policies, and seven general policies) that have been effective in addressing the following five key risk areas for young people around the world: (i) youth unemployment, underemployment, and lack of formal sector employment; (ii) early school leaving; (iii) risky sexual behavior leading to early childbearing and HIV/AIDS; (iv) crime and violence; and (v) substance abuse. The objective of this Toolkit is to serve as a practical guide for policy makers in middle-income countries as well as professionals working within the area of youth development on how to develop and implement an effective policy portfolio to foster healthy and positive youth development.Publication Ten Steps to a Results-Based Monitoring and Evaluation System : A Handbook for Development Practitioners(Washington, DC: World Bank, 2004)An effective state is essential to achieving socio-economic and sustainable development. With the advent of globalization, there are growing pressures on governments and organizations around the world to be more responsive to the demands of internal and external stakeholders for good governance, accountability and transparency, greater development effectiveness, and delivery of tangible results. Governments, parliaments, citizens, the private sector, Non-governmental Organizations (NGOs), civil society, international organizations, and donors are among the stakeholders interested in better performance. As demands for greater accountability and real results have increased, there is an attendant need for enhanced results-based monitoring and evaluation of policies, programs, and projects. This handbook provides a comprehensive ten-step model that will help guide development practitioners through the process of designing and building a results-based monitoring and evaluation system. These steps begin with a 'readiness assessment' and take the practitioner through the design, management, and importantly, the sustainability of such systems. The handbook describes each step in detail, the tasks needed to complete each one, and the tools available to help along the way.Publication World Development Report 1984(New York: Oxford University Press, 1984)Long-term needs and sustained effort are underlying themes in this year's report. As with most of its predecessors, it is divided into two parts. The first looks at economic performance, past and prospective. The second part is this year devoted to population - the causes and consequences of rapid population growth, its link to development, why it has slowed down in some developing countries. The two parts mirror each other: economic policy and performance in the next decade will matter for population growth in the developing countries for several decades beyond. Population policy and change in the rest of this century will set the terms for the whole of development strategy in the next. In both cases, policy changes will not yield immediate benefits, but delay will reduce the room for maneuver that policy makers will have in years to come.Publication World Development Report 2017(Washington, DC: World Bank, 2017-01-30)Why are carefully designed, sensible policies too often not adopted or implemented? When they are, why do they often fail to generate development outcomes such as security, growth, and equity? And why do some bad policies endure? This book addresses these fundamental questions, which are at the heart of development. Policy making and policy implementation do not occur in a vacuum. Rather, they take place in complex political and social settings, in which individuals and groups with unequal power interact within changing rules as they pursue conflicting interests. The process of these interactions is what this Report calls governance, and the space in which these interactions take place, the policy arena. The capacity of actors to commit and their willingness to cooperate and coordinate to achieve socially desirable goals are what matter for effectiveness. However, who bargains, who is excluded, and what barriers block entry to the policy arena determine the selection and implementation of policies and, consequently, their impact on development outcomes. Exclusion, capture, and clientelism are manifestations of power asymmetries that lead to failures to achieve security, growth, and equity. The distribution of power in society is partly determined by history. Yet, there is room for positive change. This Report reveals that governance can mitigate, even overcome, power asymmetries to bring about more effective policy interventions that achieve sustainable improvements in security, growth, and equity. This happens by shifting the incentives of those with power, reshaping their preferences in favor of good outcomes, and taking into account the interests of previously excluded participants. These changes can come about through bargains among elites and greater citizen engagement, as well as by international actors supporting rules that strengthen coalitions for reform.Publication Africa's Future, Africa's Challenge : Early Childhood Care and Development in Sub-Saharan Africa(Washington, DC : World Bank, 2008)This book seeks to achieve a balance, describing challenges that are being faced as well as developments that are underway. It seeks a balance in terms of the voices heard, including not just voices of the North commenting on the South, but voices from the South, and in concert with the North. It seeks to provide the voices of specialists and generalists, of those from international and local organizations, from academia and the field. It seeks a diversity of views and values. Such diversity and complexity are the reality of Sub-Saharan Africa (SSA) today. The major focus of this book is on SSA from the Sahel south. Approximately 130 million children between birth and age 6 live in SSA. Every year 27 million children are born, and every year 4.7 million children under age 5 die. Rates of birth and of child deaths are consistently higher in SSA than in any other part of the world; the under-5 mortality rate of 163 per 1,000 is twice that of the rest of the developing world and 30 times that of industrialized countries (UNICEF 2006). Of the children who are born, 65 percent will experience poverty, 14 million will be orphans affected by HIV/AIDS directly and within their families and one-third will experience exclusion because of their gender or ethnicity.
