This paper provides a selective review of the literature on the determinants of inflation in Nigeria, analyzes the dominant factors influencing inflation, presents the empirical results of a reduced-form elasticities model, and discusses the policy implications of the empirical results. The results of this analysis confirm the basic findings of earlier studies, namely that monetary expansion, driven mainly by expansionary fiscal policies, explains to a large degree the inflationary process in Nigeria. Other important factors are the devaluation of the naira and agroclimatic conditions. With respect to the depreciation of the naira, it was found that concurrent fiscal and monetary policies had a major influence on its impact on inflation. Given the considerable role of food commodities in the CPI, agroclimatic conditions (rainfall) were found to play a significant role in overall movements in prices and should be fully taken into consideration in any analysis of the inflationary process in Nigeria.

This is the first comprehensive study in the context of EMDEs that covers, in one consistent framework, the evolution and global and domestic drivers of inflation, the role of expectations, exchange rate pass-through and policy implications. In addition, the report analyzes inflation and monetary policy related challenges in LICs. The report documents three major findings: In First, EMDE disinflation over the past four decades was to a significant degree a result of favorable external developments, pointing to the risk of rising EMDE inflation if global inflation were to increase. In particular, the decline in EMDE inflation has been supported by broad-based global disinflation amid rapid international trade and financial integration and the disruption caused by the global financial crisis. While domestic factors continue to be the main drivers of short-term movements in EMDE inflation, the role of global factors has risen by one-half between the 1970s and the 2000s. On average, global shocks, especially oil price swings and global demand shocks have accounted for more than one-quarter of domestic inflation variatio--and more in countries with stronger global linkages and greater reliance on commodity imports. In LICs, global food and energy price shocks accounted for another 12 percent of core inflation variatio--half more than in advanced economies and one-fifth more than in non-LIC EMDEs. Second, inflation expectations continue to be less well-anchored in EMDEs than in advanced economies, although a move to inflation targeting and better fiscal frameworks has helped strengthen monetary policy credibility. Lower monetary policy credibility and exchange rate flexibility have also been associated with higher pass-through of exchange rate shocks into domestic inflation in the event of global shocks, which have accounted for half of EMDE exchange rate variation. Third, in part because of poorly anchored inflation expectations, the transmission of global commodity price shocks to domestic LIC inflation (combined with unintended consequences of other government policies) can have material implications for poverty: the global food price spikes in 2010-11 tipped roughly 8 million people into poverty.

This paper investigates the response of consumer price inflation to changes in domestic fuel prices, looking at the different categories of the overall consumer price index (CPI). We then combine household survey data with the CPI components to construct a CPI index for the poorest and richest income quintiles with the view to assess the distributional impact of the pass-through. To undertake this analysis, the paper provides an update to the Global Monthly Retail Fuel Price Database, expanding the product coverage to premium and regular fuels, the time dimension to December 2020, and the sample to 190 countries. Three key findings stand out. First, the response of inflation to gasoline price shocks is smaller, but more persistent and broad-based in developing economies than in advanced economies. Second, we show that past studies using crude oil prices instead of retail fuel prices to estimate the pass-through to inflation significantly underestimate it. Third, while the purchasing power of all households declines as fuel prices increase, the distributional impact is progressive. But the progressivity phases out within 6 months after the shock in advanced economies, whereas it persists beyond a year in developing countries.

June 1998 This study of inflation in Albania yields several conclusions: * Fighting inflation and keeping exports competitive requires cuts in the budget deficit and credit to government. * The strong seasonal inflation can be somewhat ameliorated by improving infrastructure and customs services. * Structural reforms and improved infrastructure should be part of all stabilization programs, because growth reduces inflation. Domac and Elbirt investigate the behavior and determinants of inflation in Albania, using three approaches. They * Decompose inflation into four components: seasonal, cyclical, trend, and random. * Rely on the widely used Granger causality test, using disaggregated data on both the consumer price index (CPI) and key economic variables. * Apply cointegration and error-correction techniques to the process of inflation, using a simple theoretical model. Using the first approach, they conclude that inflation exhibits strong seasonal patterns associated with agriculture seasonality. Peaks and troughs of monetary aggregates correspond to those of inflation, with a two-month lag. The exchange rate also exhibits stable seasonality, reaching its trough in August and tending to depreciate early in the year. The Granger causality test shows M1 (currency in circulation plus demand deposits) and the exchange rate to have predictive content for most items of the CPI. The empirical findings also indicate that credit to government is a good predictor of medical care, transportation, and communication prices. But causality also runs from the prices of bread and cereals, recreation, education, and culture to credit to government, since these items, at least during the period under consideration, are subsidized and contribute to the budget deficit. And causality runs from credit to government to the price of nontradables, highlighting the fact that an increase in the fiscal deficit would undermine Albania's competitiveness by producing appreciation in the real exchange rate. The results of cointegration and error-correction techniques confirm that, in the long run, inflation is positively related to both money supply and the exchange rate, and negatively related to real income. A 1-percent increase in M1, for example, will raise inflation by 0.41 percent; a 1-percent depreciation of the exchange rate will increase inflation by 0.17 percent; whereas a 1-percent increase in real income will reduce inflation by 0.25 percent. Inflation adjusts to its equilibrium value fairly rapidly-25 percent a month. The impact of the exchange rate on inflation occurs a month later, while the impact of real income and money take place two and four months later, respectively. The findings support the conventional elements of a typical stabilization program. Fighting inflation and keeping exports competitive requires reducing both the budget deficit and credit to government. The strong seasonal nature of inflation can be somewhat ameliorated by improving infrastructure and customs services. Structural reforms and improvements in infrastructure should be part of any stabilization program because economic growth is an antidote to inflation. This paper-a joint product of the Albania/Croatia Country Unit, Europe and Central Asia Region, and the Poverty Reduction and Economic Management Sector Unit, East Asia and Pacific Region-is part of a larger effort in the Bank to enhance the knowledge on the inflationary process and its practical implications.

The COVID-19 pandemic struck the global economy after a decade that featured a broad-based slowdown in productivity growth. Global Productivity: Trends, Drivers, and Policies presents the first comprehensive analysis of the evolution and drivers of productivity growth, examines the effects of COVID-19 on productivity, and discusses a wide range of policies needed to rekindle productivity growth. The book also provides a far-reaching data set of multiple measures of productivity for up to 164 advanced economies and emerging market and developing economies, and it introduces a new sectoral database of productivity. The World Bank has created an extraordinary book on productivity, covering a large group of countries and using a wide variety of data sources. There is an emphasis on emerging and developing economies, whereas the prior literature has concentrated on developed economies. The book seeks to understand growth patterns and quantify the role of (among other things) the reallocation of factors, technological change, and the impact of natural disasters, including the COVID-19 pandemic. This book is must-reading for specialists in emerging economies but also provides deep insights for anyone interested in economic growth and productivity. Martin Neil Baily Senior Fellow, The Brookings Institution Former Chair, U.S. President’s Council of Economic Advisers This is an important book at a critical time. As the book notes, global productivity growth had already been slowing prior to the COVID-19 pandemic and collapses with the pandemic. If we want an effective recovery, we have to understand what was driving these long-run trends. The book presents a novel global approach to examining the levels, growth rates, and drivers of productivity growth. For anyone wanting to understand or influence productivity growth, this is an essential read. Nicholas Bloom William D. Eberle Professor of Economics, Stanford University The COVID-19 pandemic hit a global economy that was already struggling with an adverse pre-existing condition—slow productivity growth. This extraordinarily valuable and timely book brings considerable new evidence that shows the broad-based, long-standing nature of the slowdown. It is comprehensive, with an exceptional focus on emerging market and developing economies. Importantly, it shows how severe disasters (of which COVID-19 is just the latest) typically harm productivity. There are no silver bullets, but the book suggests sensible strategies to improve growth prospects.
