Monetary Policy and the German Unemployment Problem in Macroeconomic Models
Having the high unemployment in Germany in mind, this book discusses how macroeconomic theory has evolved over the past forty years. It shows that in recent years a convergence has taken place, with modern models embodying a Keynesian transmission mechanism, monetarist policy implication, and modeling techniques inspired by new classical economics and real business cycle theory. It also probes in which direction models may be extended from here. Empirically, the book uses different econometric techniques to investigate the relevance and implications of different macroeconomic theories for German data. A key question this book investigates is the role of demand and supply side conditions for the increase in the German unemployment rate. On a policy level, the book relates the implications of the different theories to the ongoing debate on the appropriate roles of demand and supply side policies for curing the German unemployment problem.
When and How to Adjust Beyond the Business Cycle? A Guide to Structural Fiscal Balances
Technical Notes and Manuals are produced by IMF departments to expand the dissemination of their technical assistance advice. These papers present general advice and guidance, drawn in part from unpublished technical assistance reports, to a broader audience. This new series was launched in August 2009.
Structural Transformation and Tax Efficiency
Structural transformation has resulted in an increasing share of services in aggregate value-added in advanced and developing countries across the world. We analyze the impact of this shift into services on countries’ efficiency in collecting the value-added tax (VAT). The analysis is based on two alternative measures of VAT efficiency: (1) the VAT C-efficiency, using a broad panel of 134 countries over the period 1970-2014; and (2) the VAT gap using a more granular, proprietary dataset that draws on the results of IMF’s Revenue Administraion-Gap Analysis Program covering 24 countries over the period 2004-2016. We find that a higher share of services in aggregate value-added reduces the VAT efficiency, and that this adverse effect is mainly a result of a rise of non-tradable services, which in turn contributes to a narrowing of the VAT base.
The Macroeconomics of Medium-Term Aid Scaling-Up Scenarios
We develop a model to analyze the macroeconomic effects of a scaling-up of aid and assess the implications of different policy responses. The model features key structural characteristics of low-income countries, including varying degrees of public investment efficiency and a learning-by-doing (LBD) externality that captures Dutch disease effects. On the policy front, it distinguishes between spending the aid, which is controlled by the fiscal authority, and absorbing the aid - financing a higher current account deficit - which is influenced by the central bank's reserve accumulation policies. We calibrate the model to Uganda and run several experiments. We find that a policy mix that result...
Oil Windfalls in Ghana
We use a calibrated multi-sector DSGE model to analyze the likely impact of oil windfalls on the Ghanaian economy, under alternative fiscal and monetary policy responses. We distinguish between the short-run impact, associated with demand-related pressures, and the medium run impact on competitiveness and growth. The impact on inflation and the real exchange rate could be moderate, especially if the fiscal authorities smooth oil-related spending or increase public spending’s import content. However, a policy mix that results in both a fiscal expansion and the simultaneous accumulation of the foreign currency proceeds from oil as international reserves—to offset the real appreciation—would raise demand pressures and crowd-out the private sector. In the medium term, the negative impact on competitiveness—resulting from ”Dutch Disease” effects—could be small, provided public spending increases the stock of productive public capital. These findings highlight the role of different policy responses, and their interaction, for the macroeconomic impact of oil proceeds.
Enhancing Development Assistance to Africa
The pace of progress toward achievement of the Millenium Development Goals (MDG) in many sub-Saharan African countries remains too slow to reach targets by 2015, despite significant progress in the late 1990s. The MDG Africa Steering Group, convened in September 2007 by the UN Secretary-General, designated 10 countries for pilot studies to investigate how existing national development plans would be impacted by scaled up development aid to Africa. This joint publication of the IMF and the United Nations Development Programme reports conclusions drawn from these pilot studies and summarizes country-specific results for Benin, the Central African Republic, Ghana, Liberia, Niger, Rwanda, Tanzania, Togo, Sierra Leone, and Zambia.
The Macroeconomic Effects of Natural Resource Extraction
To investigate the effects on Papua New Guinea’s economy of substantial liquified natural gas revenues arriving in 2015, we employ a model to examine the macroeconomic effects of a scalingup of natural resource windfall revenues and the implications for a variety of policy responses. The model is a multi-sector dynamic stochastic general equilibrium (DSGE) model, and features components that allow for a detailed study of the effects of both fiscal and monetary policy in response to a positive shock to the mineral resource value of a country. The model contains tradable, non-tradable, and mining sectors, as well as an independent central bank and fiscal authority. We calibrate the model to ...
Default in Today's Advanced Economies: Unnecessary, Undesirable, and Unlikely
This note summarizes the main arguments put forward by some market commentators who argue that default is inevitable, and presents a rebuttal for each argument in turn. Their main arguments focus on the size of the adjustment and continued market concerns reflected in government bond spreads. The essence of our reasoning is that the challenge stems mainly from the advanced economies' large primary deficits. Thus, by lowering the interest bill while triggering the need to move to primary balance or a small primary surplus, default would not significantly reduce the need for major fiscal adjustment. In contrast, the emerging economies that defaulted in recent decades did so primarily as a result of high debt servicing costs, often in the context of major external shocks. We conclude that default would be ineffective and undesirable in today's advanced economies.
Analyzing Fiscal Space Using the MAMS Model - An Application to Burkina Faso
This paper analyses economic implications and the transmission mechanisms of different options for creating and using fiscal space. For creating fiscal space, we consider prioritizing expenditures, raising revenue, and scaled-up aid. Fiscal space is used for increasing health and education spending, infrastructure spending, or both. The analysis takes place within the World Bank's MAMS model, which is a multisectoral real computable general equilibrium model that incorporates the Millennium Development Goals. The model has been calibrated for Burkina Faso, which serves as an illustrative country example. Some of the key results are that absorbing a more educated labor force requires fundamental structural change in the economy; increasing health and education spending can face sizeable capacity constraints; and infrastructure spending has a positive effect on growth as well as education and health outcomes.
The Real Exchange Rate
This paper provides an assessment of real exchange rate measures and their impact on trade performance with special reference to two Pacific island countries, Fiji and Samoa. The analysis shows that the commonly used CPI-based real effective exchange rate (REER) measure provides a useful starting point of assessment, but alternative measures based on other price and cost indices should be used to check the robustness of the results, particularly given the large impact of global commodity prices on small open economies. The paper also offers some illustrations of how to quantify the impact of exchange rate movements on trade, especially in the face of data constraints in small open economies.
