Inparticular, the number of static and/or weak factors spanning thecontemporaneous common component space is allowed to be infinite. Our procedureoperates entirely in the time domain by recovering the infinite past of thecommon shocks from static aggregates and their lags. Hence, in contrast toexisting approaches, we completely avoid estimating the spectral density in apreliminary step. We develop the corresponding estimation theory andinferential framework, and demonstrate through simulation studies that ourmethod outperforms existing approaches in the literature. In an empiricalapplication to Viennese Real estate data, we show that there are sizabledifferences between the impulse response function of the static and the dynamiccommon component to the common dynamic shocks.

This paper shows that, in competitive financial markets, impactinvestors constrained to break even cannot improve on commercial finance. Westudy how scarce concessional capital can be optimally combined with no-losscapital, an approach commonly referred to as blended finance, to overcome thislimitation. In a model with private information and non-contractible effort,the optimal policy targets projects through cutoff rules that trade off impactpotential and financial viability. The results characterize when blendedfinance should enhance existing investments and when it should bring otherwiseunfunded projects to market.

This paper studies the international effects ofChina’s ban on plastic waste imports. In recent decades, high-income countries had beenreducing their plastic waste burden by exporting it to China. This changed in 2017 whenChina banned key plastic waste imports, raising concerns over creation of waste havens inother parts of the world. The paper shows that China’s policy led to a diversion of tradethat had repercussions for countries across the world. Turkey emerged as a major importerof plastic waste from high-income countries. We provide direct evidence that importers inTurkey gained economically from better access to plastic waste that could be recycled andre-used as inputs in production. But their gains did not outweigh the losses of domesticfirms that generated plastic waste and were displaced by import competition after China’sban. These domestic waste generators became more likely to mismanage their plastic waste,including through open burning. Air pollution increased more in Turkish regions wherethese waste generators were located. We model the channels of waste and recycling in agravity model of trade and the environment to explain the empirical findings and to quantifythe environmental externalities from China’s unilateral import ban Location: R42.2.113 Add Event May 26 Title : "PlasticTurkey: International Impacts of China's Waste Import Ban" Abstract : In pollution haven theories, trade and environmental policies can have signifi-cant effects on the levels and incidence of pollution and economic activity across countries,leading potentially to a race to the bottom.
