Feeling the Heat: Adapting to Climate Change in the Middle East and Central Asia
Climate change is among humanity’s greatest challenges, and the Middle East and Central Asia region is on the frontlines of its human, economic, and physical ramifications. Much of the region is located in already difficult climate zones, where global warming exacerbates desertification, water stress, and rising sea levels. This trend entails fundamental economic disruptions, endangers food security, and undermines public health, with ripple effects on poverty and inequality, displacement, and conflict. Considering the risks posed by climate change, the central message of this departmental paper is that adapting to climate change by boosting resilience to climate stresses and disasters is a critical priority for the region’s economies.
Frugality
Household savings rates in the United States have recently crept up from all-time lows. Some have suggested that a shift toward frugality will hamper GDP growth-the Keynesian "paradox of thrift." We estimate that households compensate for a fall in their asset income by saving more out of their labor income, dollar-for-dollar. In the wake of the crisis, our model predicts that such primary savings will increase, but only temporarily and modestly, as household assets stabilize. As savings flows gradually accumulate, they help rebuild corporate net worth and hence firms' capacity to make capital investments. A timely return to pre-crisis levels of capital investment would require that U.S. households save substantially more than the model predicts, starting now. Hence, we should fret that our savings rates may be too low.
Measuring the Informal Economy in the Caucasus and Central Asia
This study estimates the size of the informal economy, and the relative contribution of each underlying factor, for the Caucasus and Central Asia countries in 2008. Using a Multiple Indicator-Multiple Cause model, we find that a burdensome tax system, rigid labor market, low institutional quality, and excessive regulation in financial and products markets are determinant factors in explaining the size of the informal economy, which ranges from 26 percent of GDP in Kyrgyz Republic to around 35 percent of GDP in Armenia. Furthermore, the results show that higher levels of informality increase the levels of self employment and the percentage of currency held outside the banking system.
Remittances Channel and Fiscal Impact in the Middle East, North Africa, and Central Asia
This paper identifies a remittances channel that transmits exogenous shocks, such as business cycles in remittance-sending countries, to the public finances of remittance-receiving countries. Using panel data for remittance-receiving countries in the Middle East, North Africa, and Central Asia, three types of results emerge. First, remittances appear to be strongly procyclical vis-à-vis sending country income. Second, remittances tend to be spent on consumption of both imported and domestically produced goods, rather than on investment. Third, shocks in the sending countries are transmitted via remittances to the public finances - specifically, tax revenues - of receiving countries. In the case of the 2009 global downturn, this impact was particularly strong for several countries in the Caucasus and Central Asia, whereas in the subsequent recovery in 2010 virtually all receiving countries benefitted from an upturn in remittance-driven tax revenues.
Understanding U.S. Wage Dynamics
In this paper, we undertake empirical analysis to understand U.S. wage behavior since the beginning of the new millennium. At the macroeconomic level, we find that a productivity-augmented Phillips curve model explains the data fairly well. The model reveals that the upward pressure on wage growth from recent tightening in the labor market has been dampened by a persistent decline in trend labor productivity growth and the share of income that accrues to labor. These themes are reinforced and complemented at the micro-economic level. Lower regional unemployment puts an upward pressure on wages of individuals, although this effect has become weaker since 2008. But there is downward pressure on wages for individuals with occupations that are exposed to automation and offshoring, and in industries with a higher concentration of large firms. All these factors appear to play a role illustrating why it is difficult to single out any one culprit for the observed wage growth moderation.
Fiscal Sustainability in Remittance-Dependent Economies
We investigate the impact of remittances on public debt sustainability and detail how the traditional debt-to-GDP ratio can be modified to create a more accurate representation of debt sustainability for a country that receives significant remittance inflows. The main result is that inclusion of remittances into the traditional debt sustainability analysis alters the amount of fiscal adjustment required to place debt on a sustainable path. While preliminary, these results are indicative of how a one-size-fits-all stability analysis may be inappropriate when evaluating the stance of fiscal policy for countries with different balance of payments characteristics.
What Explains the Decline of the U.S. Labor Share of Income? An Analysis of State and Industry Level Data
The U.S. labor share of income has been on a secular downward trajectory since the beginning of the new millennium. Using data that are disaggregated across both state and industry, we show the decline in the labor share is broad-based but the extent of the fall varies greatly. Exploiting a new data set on the task characteristics of occupations, the U.S. input-output tables, and the Current Population Survey, we find that in addition to changes in labor institutions, technological change and different forms of trade integration lowered the labor share. In particular, the fall was largest, on average, in industries that saw: a high initial intensity of “routinizable” occupations; steep declines in unionization; a high level of competition from imports; and a high intensity of foreign input usage. Quantitatively, we find that the bulk of the effect comes from changes in technology that are linked to the automation of routine tasks, followed by trade globalization.
What is Keeping U.S. Core Inflation Low
Over the past two decades, U.S. core PCE goods and services inflation have evolved differently. Against the backdrop of global concerns of low inflation, we use this trend as motivation to develop a bottom-up model of U.S. inflation. We find that domestic forces play a larger role relative to foreign factors in influencing core services inflation, while foreign factors predominantly drive core goods price changes. When comparing forecasting performance, we find that both the aggregate Phillips curve and the bottom up approach give low root mean square errors. The latter, however, is more informative in tracing the effects of shocks and understanding the exact channels through which they affe...
Understanding Euro Area Inflation Dynamics: Why So Low for So Long?
Despite closing output gaps and tightening labor markets, inflation has remained low in the euro area. Based on an augmented Phillips Curve framework, we find that this phenomenon—sometimes attributed to low global inflation—has been primarily caused by a remarkable persistence of inflation, keeping it low despite the reduction in slack. This feature is shown to be specific to the euro area (in comparison with the United States). Monetary policy needs to stay accommodative to help guide inflation back to target.
IMF-Supported Programs
Research work by the IMF’s staff on the effectiveness of the country programs the organization supports, which has long been carried out, has intensified in recent years. IMF analysts have sought to “open up the black box” by more closely examining program design and implementation, as well as how these influence programs’ effectiveness. Their efforts have also focused on identifying the lending, signaling, and monitoring features of the IMF that may affect member countries’ economic performance. This book reports on a large portion of both the new and the continuing research. It concludes that IMF programs work best where domestic politics and institutions permit the timely implementation of the necessary measures and when a country is vulnerable to, but not yet in, a crisis. It points to the need for a wider recognition of the substantial diversity among IMF member countries and for programs to be tailored accordingly while broadly maintaining the IMF’s general principle of uniformity of treatment.
