Plastic Turkey: International Leakages of China's Waste Contamination Policy
écrit avec Deniz Atalar and Swati Dhingra
Global trade in plastic waste has increased by over 700 percent since the 1990s. Exports of plastic waste have flowed primarily from developed economies to emerging markets, raising concerns over the environmental and public health consequences of less stringent regulations in importing countries. Following domestic concerns, China tightened restrictions on contamination levels of plastic waste imports in 2017. Being the world's major importer of plastic waste,
China's policy led to a dramatic diversion of trade. This paper shows that Turkey emerged as a major importer of plastic waste from more advanced economies. Importers in Turkey got access to cheaper foreign plastic waste and reduced their domestic purchases. Using a unique dataset on waste disposal by domestic firms, we show that firms in Turkey that generated plastic waste became more likely to mismanage it, including through burning or dumping in water bodies. Emissions from waste management increased in Turkish regions that were more specialised in production of the waste products banned by China. We model this channel of environmental degradation in a gravity model of trade and the environment to quantify the global spillovers of environmental externalities through trade and to examine the welfare impacts of the policy.

Filling the map: improving the local estimates of intergenerational mobility
A growing body of literature indicates that the primary contributors to upward mobility are the local characteristics of the environments in which children are raised (i.e., neighborhoods). However, the standard methodology fails to consider the varying population size and proximity of these local areas when estimating intergenerational mobility rates, often resulting in imprecise estimates, particularly for low-populated areas or relevant subgroups. This paper proposes an alternative Bayesian multilevel methodology for estimating intergenerational mobility rates at a very local level, taking into account both the heterogeneous population sizes across areas and their geographical proximity. We apply this methodology to rich administrative tax data from Spain used to study intergenerational income mobility. Preliminary results indicate that this approach yields more reliable estimates, especially in areas with very low sample sizes, expanding the scope of spatial analysis of mobility rates and allowing for the uncovering of potentially new findings regarding the role of the characteristics of very local areas in upward mobility.
