Spoiler: Putin’s war against Ukraine has led to decreased supplies of several goods which Ukraine and Russia exports. We have already seen price hikes of oil and gas followed by decreased supply and higher prices of wheat, sunflower oil, fertilizers, steel to mention some of the most important goods. The world will be poorer, and the poorest people will be hit hardest by Putin.
The effects are felt directly and indirectly. The direct effects concern those firms and households who use gas and oil for as energy or wheat when baking bread. They are also felt indirectly as goods that are produced with gas, oil, wheat, sunflower, and steel become more expensive. The effects are stronger in countries where imports of the goods are relatively large, account for a large part of final domestic demand and the more elastic demand for those goods are.
The effects are stronger in continents and countries with a relatively large share of poor households. More families will be poor. But the effects will reach further. Increased poverty is associated with less nutrition, shorter life expectance and higher natal mortality numbers. Putin kills people today and in the future. In addition to that, his war will lead to fewer births.
