Shedding jobs can be costly for productivity once the pandemic subsides, which makes it desirable to preserve employment even if productivity is temporarily low. However, in the presence of collateral constraints, firms may not be able to finance the current wage bill and be forced to dismiss workers. And collateral constraints may become tighter if the value of firms fall, reflecting expectations of future profits and productivity. This interaction implies amplification of the health shock and possibly multiplicity of equilibria. The model suggests a justification of several current unconventional policy proposals, including temporary subsidies to wage costs and credit guarantees.<\/span><\/li>\n<li><a href=\"http:\/\/sites.rutgers.edu\/roberto-chang\/wp-content\/uploads\/sites\/408\/2020\/05\/CVPandemics-Covid19.pdf\"><strong>Economic Policy Incentives to Preserve Lives and Livelihoods<\/strong><\/a> , with Andr\u00e9s Velasco. <strong>Working Paper, April 2020<\/strong><em><strong>. <\/strong><\/em>Comments are most\u00a0 welcome. The Covid-19 shock is not exogenous: its magnitude depends on individual decisions to adhere to lockdowns and other public policy directives, decisions that are influenced by economic policy. This fact has crucial implications for the analysis of current economic policy proposals and their interaction with public health measures. We develop these implications in the context of a model that, in spite of its simplicity, is the first one to feature complete microfoundations of the joint determination of infection and economic outcomes. This means, in particular, that our analysis is immune to the Lucas Critique in a way that existing studies are not. Many practical lessons emerge from the analysis: most importantly, we show how public health measures and economic policies can complement each other, reducing the cost of preserving both lives and livelihoods.<\/li>\n<li><strong><a href=\"https:\/\/voxeu.org\/article\/economic-policy-incentives-fight-against-pandemics\">Economic Policy Incentives in the Fight Against Pandemics<\/a><\/strong> , with Andr\u00e9s Velasco, a column for <em>Vox<\/em> discussing the ideas above<\/li>\n<li><a href=\"https:\/\/www.project-syndicate.org\/commentary\/policy-response-to-covid19-in-latin-america-by-roberto-chang-1-and-andres-velasco-2020-03\"><strong>The Virus Turns South<\/strong><\/a>, with Andr\u00e9s Velasco, March 2020, for <em>Project Syndicate<\/em><\/li>\n<li><strong><a href=\"http:\/\/americat.barcelona\/es\/roberto-chang--economista-que-un-organismo-microscopico-amenace-con-barrernos-subitamente-del-planeta-nos-recuerda-lo-pequenyos-que-somos?fbclid=IwAR3jDSVW3U5KjNO7tfcJbyFKRo25mqBpXRkc9NBcv3eXk0fnigk-B70CDHg\">Interview: Casa America Catalunya<\/a><\/strong> on the Covid-19 crisis (in Spanish)<\/li>\n<li><a href=\"https:\/\/www.americasquarterly.org\/content\/roadmap-confronting-covid-19-latin-america?fbclid=IwAR1u83IWHd-120qvCK_yegphVxSfYIebBHXEDUoyuT7DDD-d0YSHi1ZcywQ\"><strong>Ethical and Economic Imperatives in Confronting Covid-19<\/strong><\/a> An open letter written by four past Latin American presidents and nine prominent economists.\u00a0 This version was published in <em>Americas Quarterly<\/em>.<\/li>\n<li><a href=\"https:\/\/www.worldbank.org\/en\/news\/video\/2020\/04\/07\/macroeconomic-policy-in-the-time-of-covid-19-a-primer-for-developing-countries\"><strong>Macro Policy in the Time of COVID-19<\/strong>\u00a0<\/a> A World Bank e-seminar organized by Norman Loayza.
