The economic geography of transition economies has changed dramatically over the last quarter century, with large urban areas growing fast and many smaller places facing declining populations. Using a high-resolution spatial growth model, this column projects the transition economies as a whole to perform economically well over the next decades, especially the region’s densest places. Large-scale infrastructure projects such as the Belt and Road Initiative will have a positive impact, but not more so than modest reductions of general trade frictions.

Large internal wage disparities between cities are a common feature in countries around the world. Using data from Germany, this column argues that one key driver of this is rising assortative matching of high-quality workers and plants in large cities. One promising strategy to reduce spatial wage disparities is to improve matching within small cities.

Spatial inequality is understood as a function of geography or administrative planning, but its relation to ethnic segregation is less well understood. This column analyses this relationship using regional data for 71 countries with different levels of economic development. The degree of spatial concentration of ethnic groups is a robust and highly significant predictor of within-country income disparities. More ethnically segregated countries experience higher levels of spatial inequality and are thus more prone to conflict.

Spatial inequalities in territorial-based greenhouse emissions matter in terms of regulation, both at the international and subnational levels. This column decomposes these inequalities worldwide for the two major greenhouse gases over the period 1970–2008. Within-country inequalities are larger, and rising, while between-country inequalities are smaller and falling. Moreover, social tensions arising from the discrepancy between the distribution of emissions and the distribution of damages appear to be larger within than between countries, and larger for carbon dioxide than for methane.

Does government quality affect the size and evolution of regional inequality? This column approaches this question using regional data for 46 countries with different degrees of economic development over the period 1996-2006. We find that there is a strong negative association between quality of government and within-country disparities. Countries with better quality of government register lower levels of spatial inequality.

This column traces the economic evolution of France’s regions over the last 140 years to test the predictions of new economy geography. Both manufacturing and services experienced a bell-shaped curve of spatial development, in which spatial concentration initially increased and then decreased. While transport costs played a key role, positive spillovers are an increasingly important source of agglomeration gains.
