The pandemic-induced global economic crisis has contributed to the re-emergence of sovereign default risk, especially for emerging and developing economies, and has directed attention to the impact of the institutions that are tasked with attempting to predict defaults: the international credit rating agencies. This paper describes four main challenges posed by credit rating agencies, especially from a developing and emerging economies perspective: potential bias in ratings, pro-cyclicality of ratings, governance issues and conflicts of interest, and incorporation of climate risk. It concludes with potential policy solutions addressed at ratings agencies, regulators, and policy makers.…

The COVID-19 pandemic has caused the most universal health and socio-economic crisis in recent history. However, the magnitude of the economic damage has differed widely; some countries were hit particularly hard, while others have managed to weather the storm much better. In this paper, we use cross-country regression analysis to identify factors that help explain the differences in the growth impact of the COVID-19 shock. Our findings underscore the critical role of balancing health and economic concerns in managing the pandemic as both a country’s exposure to the coronavirus and the stringency of containment measures are strongly correlated with its growth performance. In addition,…

In Article 25 (1) of the Universal Declaration of Human Rights, the United Nations recognized in 1948 the basic human right to “security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond ... control.” This paper examines how economic insecurity is related to, yet different from, poverty and inequality, why it matters for human well-being and how it has been changing in different countries around the world in recent years. The paper concludes with discussion of how economic insecurity has been and will be affected by the Covid-19 pandemic/recession.

Productive and technological capabilities matter. The more conventional strands of the literature have emphasized them as major engines of export, growth and development. But how they matter is less clear, and many open questions remain on how capabilities influence export dynamics at microeconomic level. This paper empirically investigates their role on export dynamics in 40 developing countries between 2002 and 2012. In doing so, the paper exploits a country-sector-year database containing exporter-level statistical information. The empirical analysis shows that, within sectors, countries with higher productive capacities have more exporters, and the exporters are larger and charge…

We provide a history of past periods of rapid technological change starting from the Industrial Revolution continuing up to today. We find that it takes decades for technological breakthroughs to make a difference to the aggregate economy. The reason for this delay is that to realize the value of these breakthroughs requires complementary investments. Second, for good or for bad, government has played an important role in facilitating these transitions through both investments in physical infrastructure and legal reforms. We also emphasize that because technological breakthroughs are difficult to predict, the responses of governments are necessarily improvisational.

This paper argues that SDRs should become a more relevant instrument of international monetary cooperation. This requires transforming them into a pure reserve asset and the IMF into a fully SDR-funded institution. SDRs would then be issued counter-cyclically and treated as deposits of countries in the IMF, which can in turn lend to countries. This approach would correct basic deficiencies of the current global monetary system. Complementary reforms include a substitution account for an orderly and smooth transition from major reserve currencies to SDRs, and the issuance of SDR-denominated bonds as an alternative to other major short-term assets.

To achieve the greatest possible human welfare, the Stockholm Environment Institute’s Climate and Regional Economics of Development (CRED) model calls for rapid reduction of greenhouse gas emissions to keep cumulative 21st century carbon dioxide emissions below 2,000 Gt. We explain why as some other models claim very slow emission reductions are best. We make three changes to the basic assumptions of the well-known DICE model to include the most recent estimates of economic damages from climate change, express greater concern about the well-being of future generations, and expect rich countries to invest in emissions and poverty reduction in poorer countries.

This paper assesses the effects of combining fiscal austerity with flexibilization policies aimed at reducing labour costs and increasing competitiveness. Core to our analysis is a global perspective where the aggregation problem is fully taken into account. We derive a stylized macroeconomic framework of distributive and demand dynamics. We show that even in export-led regimes, after considering global feedbacks, flexibilization policies do not lead to higher income and employment. Rather, the end result is contractionary. Over time, the world economy is essentially wage-led and responds positively to coordinated Keynesian stimuli.

Decomposition of real commodity prices suggests four super-cycles during 1865-2009 ranging between 30-40 years with amplitudes 20-40 percent higher or lower than the long-run trend. Non-oil price super-cycles follow world GDP, indicating they are essentially demand-determined; causality runs in the opposite direction for oil prices. The mean of each super-cycle of non-oil commodities is generally lower than for the previous cycle, supporting the Prebisch-Singer hypothesis. Tropical agriculture experienced the strongest and steepest long-term downward trend through the twentieth century, followed by non-tropical agriculture and metals, while real oil prices experienced a long-term upward…

This paper assesses the effectiveness of non-tariff special and differential treatment (SDT) offered exclusively to the least developed countries by WTO agreements. SDTs are inefficient in at least four aspects. First, they are not easily accessed as they require a certain level of institutional capacity. Second, when accessible they either need to be complemented by other policy interventions or are offset by measures taken elsewhere. Third, some do not respond to LDC needs. Fourth, many are too vaguely defined to provide concrete benefits. Effectiveness can be enhanced by increased LDC ownership and improved policy coherence by trading and development partners.

A fundamental shift in macroeconomic policy thinking is taking place. This shift opens a space for implementing policies that promote growth and reduce poverty in developing countries. In this paper, policies for post-conflict and resource-rich economies are outlined. Fiscal policy would focus on revenue mobilization, scaling-up public investment, and preventing over-heating. Monetary policies would revive the financial sector, prevent inflationary pressures and stimulate private sector investment. Exchange rate policies should focus on achieving slow depreciation and maintaining international competitiveness. These policies should not be considered in isolation from each other, but in…

With bank-level data from 81 developing countries, the paper shows that increased foreign bank presence is associated with increased reliance on non-deposit based funding, which leads to higher interest rate spreads, less credit to the private sector, and higher volatility in bank loans. Foreign bank entry significantly reduces domestic banks’ share of deposits while foreign banks typically allocate less of their assets and deposits to lending. As domestic banks lose their deposit base, they rely on non-deposit based funding, but its higher costs and uncertainty force domestic banks to reduce their lending activities.
