SUMMARY:Global Environmental Policy Seminar with Ishan Nath
LOCATION:Y2E2 Building 299\, 473 Via Ortega\, Stanford\, CA 94305
DESCRIPTION:Trade Policy and Food Security with Climate and Geopolitical R
 isk\n\nThis paper evaluates the effects of trade openness on reliable acc
 ess to affordable food. We start by showing that the transmission of extr
 eme heat shocks to domestic food prices is weaker in countries with great
 er trade integration\, even conditional on level of development\, because
  productivity shocks are not highly correlated across space. On the other
  hand\, importing countries face disproportionate vulnerability to weathe
 r and policy shocks in countries from which they source. We show that glo
 bal wheat prices diverged in the aftermath of the disruption to Ukrainian
  exports in 2022\, with price increases strongly concentrated in countrie
 s importing directly from Ukraine. More broadly\, importers face similar 
 effects from extreme heat shocks in source countries\, suggesting that gl
 obal agricultural markets are segmented and countries face adjustment cos
 ts to establishing new import sources. We plan to calibrate a quantitativ
 e trade model that rationalizes the patterns observed in the data and use
  it to compare the stability of food prices under varying levels of trade
  openness\, as well as in policy scenarios that specifically subsidize im
 port source diversification.\n\nBio\n\nIshan Nath is an Assistant Profess
