"Biological diversity in General Equilibrium"

Abstract: I develop a multi-country dynamic general equilibrium model where biodiversity augments production and diffuses across borders. Using EU-27 ecological overlap matrices, I quantify cross-border spillovers and link conservation and land-input choices to agricultural productivity, trade, and welfare. Policy counterfactuals include targeting conservation finance to high-multiplier emitters and receivers, designing a market for biodiversity investment, and assessing distributional effects by exposure. Ongoing EU estimates indicate sizable gains from coordinated action relative to unilateral policies.

"Wasteconomics: The role of Chinese waste-import policies on US recycling sector" (with Hasan Çetin and Ekin Ulusoy)

Abstract: China’s 2017 National Sword cut allowable contamination in imported recyclables to 0.5%. We study the U.S. recycling sector’s response in trade, processing, dumping, and prices. We build a two-country open circular-economy model where households generate waste, and waste managers either recycle or dump domestic and imported waste to supply a recycled input used with labor and capital. Calibrated to U.S. plastic-waste data, the model quantifies changes in recycling rates, trade volumes, and allocations under alternative policies.
