This paper proposes the use of synthetic training data generated by large language models
to improve machine learning SDG classifiers. It shows that supplementing existing training data with
synthetic data produced by the ChatGPT tool improves the performance of the SDGClassy classifier.
This addition of synthetic data is especially useful in building SDG classifiers given the limited availability
of properly labeled data and the complex, interconnected nature of the SDGs. Synthetic data thus enables
more effective machine-learning applications in this context.

The pandemic has progressed differently across the world. Using monthly data on COVID-19 cases and fatalities, we evaluate whether income inequality is an important factor in explaining cross-country differences in the spread and mortality of the virus. The results show that income inequality is positively correlated with the number of COVID-19 cases. Higher income inequality is associated with a more rapid spread of the virus and an increase in the number of cases, indirectly increasing mortality rates as well. Also, higher levels of inequality are associated with reduced effectiveness of social distancing measures in containing new infections. Thus, elevated inequalities place…

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.

This paper examines the experience of a set of countries that performed relatively well in coping with the COVID-19 crisis. The goal is to garner insights and lessons that can help countries that may experience initial or second-round outbreaks of the pandemic in the future. The paper finds healthcare, social protection, and overall governance systems as the three main determinants of COVID-19 strategies and their success. Though unique country-specific factors played an important role in confronting the pandemic in some countries, their role was generally mediated through one or the other of the above three main determinants. The findings of the paper suggest that establishing universal…

The COVID-19 pandemic is entailing huge costs worldwide. To help developing countries formulate policy responses to minimize negative impacts of the COVID-19, possible size and duration of the shocks on most vulnerable countries, i.e., least developed countries (LDCs) and Small Island Developing States (SIDS), and their resilience to overcome the shocks need to be assessed. This paper quantitatively examines possible paths of LDCs and SIDS recovering from the impacts of the COVID-19 crisis, using an autoregressive model of income growth and a panel regression model of external demand for LDCs and SIDS. Evidence from the experience of the 2007-08 global financial crisis suggests that the…

While migration and population displacement has always been part of the human experience, the context within which it occurs today has materially changed. Migration has become an important part of economic globalization and closely related to countries´ development process. Conflicts, poverty, natural disasters and climate events are also forcing people to migrate in an ever-increasing number. For many low-income countries with large number of internally-displaced people, on the other hand, the high economic costs are making it more difficult for them to invest in SDG implementation. Developing countries also host most of the externally-displaced people at high economic costs, which…

Economic diversification is very relevant for poorer developing countries to create jobs and foster economic development. That need has been recognized in key internationally agreed development goals. The empirical economic literature has identified several stylized facts about the pattern of diversification of economies, but the development of explanations for those patterns in general has been only loosely associated with economic theory on growth, trade, technology change and structural transformation. Making that connection is relevant because it could inform policymakers in developing countries in designing and implementing policies for promoting diversification. This paper presents…

This paper revisits the earlier assessments of the Palma Proposition and the ‘Palma Ratio’. The former is a proposition that currently changes in income or consumption inequality are (almost) exclusively due to changes in the share of the richest 10 per cent and poorest 40 per cent because the ‘middle’ group between the richest and poorest always capture approximately 50 per cent of gross national income (GNI). The latter is a measure of income or consumption concentration based on the above-mentioned proposition and calculated as the GNI capture of the richest 10 per cent divided by that of the poorest 40 per cent. In this paper we do the following: note the use already being made of…

China has departed from the East Asian model of development by letting inequality to rise to a high level, which is contributing to China’s current problems of macroeconomic imbalance, declining efficiency of capital, and rising social tensions. If inequality persists, China may get caught in the “inequality-trap,” which may then lead it to the “middle income trap (MIT).” Fortunately, China still has the levers to pull to reduce inequality and avoid MIT. Measures along both the “wage route” and the “redistributive route” can be adopted for this purpose. In addition, China may pursue the “cooperative route” to more equitable distribution.

Analyses of redistributive policies often focus on income flows to examine the nexus between redistribution and economic growth. With strengthening signs of growing economic inequality in many countries, an increasing number of economists investigated the existence and nature of a hypothetical trade-off between economic growth and equity. As signs of unsustainable development are strengthening more generally, this paper proposes to look at the broader nexus between redistribution, equity and sustainable development, emphasizing its social and environmental dimensions. It does so by first proposing an analytical framework defining the role of redistributive policies in shaping the private…

The paper discusses the progress of Indian economy and its policies since the broad-based structural reforms initiated in 1991 with a special focus on the recent downturn following the global financial crisis. The paper is structured into two parts: first part discusses the major economic and social achievements of India since 1991, it identifies the causes of the recent downturn, and the policy responses to revive the economy. In the second part, the paper outlines the major challenges India is facing and the policies and reforms that need to be implement to achieve sustainable development.
