CONCLUSIONS Re-confirmthatproportionaltradecostscannotlead to home bias. Fixed export costscan help. The mechanism: decreasecorrelationbetweenlaborincome and capital income. Incompletemarketscan help: more robustresults and betteroutcomes in terms of VWW statistic and consumption – RER anomaly. Show how a productivityshockcantransforminto a redistributiveshock. Introducedemandshocksinto a more intuitive way. 15/15
