Although both shocks deliver similar macroeconomic dynamics under an empirical Taylor rule, they generate very different dynamics under optimal monetary policy. Following productivity uncertainty shocks, the optimal monetary policy achieves joint stabilization of output gaps and inflation. In contrast, in response to cost-push uncertainty shocks, the monetary authority faces a trade-off between the output gap and inflation stabilization. Our result shows that it is important for welfare-maximizing central banks to distinguish the source of uncertainty shocks.","PeriodicalId":330048,"journal":{"name":"Macroeconomics: Aggregative Models eJournal","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127942868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we develop a multiple equilibria behavioural business cycle model that can account for demand or supply collapses due to abrupt drops in consumer confidence, which affect both consumption propensity and investment. We show that, depending on the model parameters, four qualitatively different outcomes can emerge, characterised by the frequency of capital scarcity and/or demand crises. In the absence of policy measures, the duration of such crises can increase by orders of magnitude when parameters are varied, as a result of the ``paradox of thrift''. Our model suggests policy recommendations that prevent the economy from getting trapped in extended stretches of low output, low investment and high unemployment.","PeriodicalId":330048,"journal":{"name":"Macroeconomics: Aggregative Models eJournal","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114817319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attentive firms make smaller mistakes, and mistakes of the same size are punished more by financial markets during downturns. We explain these phenomena with a business cycle model in which firms, owned by risk-averse investors, rationally allocate costly attention across states. When aggregate productivity is low, there are higher rewards for delivering profits, and firms optimally pay more attention and make smaller mistakes. Endogenously counter-cyclical attention generates quantitatively significant asymmetric, state-dependent shock propagation and stochastic volatility of output growth.","PeriodicalId":330048,"journal":{"name":"Macroeconomics: Aggregative Models eJournal","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123281996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the present study investigates the differences in two groups of emerging countries, namely, those in Asia and Latin America. This study first documents that Asian economies are characterized by a higher trade balance share volatility, higher autocorrelations in key macroeconomic variables, higher contributions of trend productivity shocks to fluctuations in key macroeconomic variables, and lower consumption volatility, than Latin American economies. By estimating dynamic stochastic general equilibrium (DSGE) models buffeted with various structural shocks and frictions and performing a counterfactual analysis, this study further suggests the key sources of the differences. First, the first three differences are mainly explained by a higher persistence of trend productivity shocks in Asia than in Latin America. Second, the differences in consumption volatility appear to arise from a higher labor supply elasticity in Asia than in Latin America. We further provide data on policy regime changes and labor markets in both regions to explain the differences in their economic structure. The differences in the contribution of trend productivity shocks in economic fluctuations of the two groups also provide a partial explanation of the discrepancy in the role of trend shocks in past studies.","PeriodicalId":330048,"journal":{"name":"Macroeconomics: Aggregative Models eJournal","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128477209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
