Recent micro level data from East Africa is used to benchmark aggregate data and assess the role of agricultural inputs in explaining variation in crop yields on smallholding plots. Fertilizer, improved seeds, protection against erosion and pesticides improve crop yields in Rwanda and Ethiopia, but not Uganda, possibly associated with lack of use there. With all positive yield determinants in place, wheat and maize yields could increase fourfold.
The data hints at the negative effect of climate change on yields and the benefits of accompanying measures to mitigate its adverse impact (access to finance and protection against erosion). The adverse effect of crop damage on yields varies between 12/13 percent (Rwanda, Uganda) to 36 percent (Ethiopia). Protection against erosion and investment financing mitigate these effects considerably.
A large share of cross-country differences in productivity is explained by differences in agricultural productivity. Using a combination of sub-national agricultural statistics and geospatial datasets on crop-specific potential yields, we study the main drivers of this variation from a macroeconomic perspective. We find that differences in geographically-induced crop-specific comparative advantages can explain a substantial share of the variation in yields across the world. Data reveal substantial gaps between potential and observed yields in most countries. When decomposing these within country gaps, we find that crop selection gaps are on average larger than those induced by input usage alone. The results highlight the importance of understanding the interaction of geography and crop selection drivers in assessing aggregate agricultural productivity differences.

Technological progress in the exploration and production of oil and gas during the 2000s has led to a boom in upstream investment and has increased the domestic supply of fossil fuels. It is unknown, however, how many jobs this boom has created. We use time-series methods at the national level and dynamic panel methods at the state-level to understand how the increase in exploration and production activity has impacted employment. We find robust statistical support for the hypothesis that changes in drilling for oil and gas as captured by rig-counts do in fact, have an economically meaningful and positive impact on employment. The strongest impact is contemporaneous, though months later in the year also experience statistically and economically meaningful growth. Once dynamic effects are accounted for, we estimate that an additional rig-count results in the creation of 37 jobs immediately and 224 jobs in the long run, though our robustness checks suggest that these multipliers could be bigger.

The work on the small states is an important component of the IMF’s global policy agenda. Among the 36 member countries covered by the IMF Asia and Pacific Department (APD), 13 countries are developing small states—most of which are Pacific islands. As part of APD’s ongoing effort to increase its engagement with regional small states and their development partners and enhance information sharing within the IMF, this issue marks the launch of the APD Small States Monitor, a quarterly bulletin featuring the latest economic developments, country notes from the most recent Article IV staff reports, special topics, past and upcoming events, and forthcoming IMF research on small states. In future issues, we will also host contributions from the authorities of small states and their development partners on key policy topics. Our goal is to exchange knowledge and deepen our understanding of the policy challenges these economies face to better tailor our policy advice.
This paper highlights that one of the most dramatic developments in the 20th century was the entry of women into economic and political spheres previously occupied almost exclusively by men. Although women are making progress in eliminating gender disparities, they still lag men in the workplace and in the halls of government. These gaps are found throughout the world, but are particularly pronounced in developing economies. So far, the greatest success has been in reducing education and health disparities and the least in increasing women’s economic and political influence.
