The model combines the building blocks of standard DSGE models (e.g., price and wage rigidities and adjustment costs) with the following features that better describe the Brazilian economy: (i) a fiscal authority pursuing an explicit target for the primary surplus; (ii) administered or regulated prices as part of consumer prices; (iii) external finance for imports, amplifying the effects of changes in external financial conditions on the economy; and (iv) imported goods used in the production function of differentiated goods. It also includes the presence of financially constrained households. We estimate the model with Bayesian techniques, using data starting in 1999, when inflation targeting was implemented. Model evaluation, based on impulse response functions, moment conditions, variance error decomposition and initial forecasting exercises, suggests that the model can be a useful tool for policy analysis and forecasting.","PeriodicalId":332423,"journal":{"name":"Brazilian Review of Econometrics","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132763611","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}

We document evidence that a model that takes this specific type of technical progress into account is better suited to explain the Brazilian economy over the long term. We then present a DSGE [Dynamic Stochastic General Equilibrium] model with two sectors that incorporates technical progress in the investment goods sector and estimate the model for Brazil. The results demonstrate that productivity shocks in the investment goods sector are more volatile and persistent than in the final goods sector and that the output gap has a greater variance in the two-sector model. In addition, these results recommend a more rigorous monetary policy prescription to improve the economy’s well-being.","PeriodicalId":332423,"journal":{"name":"Brazilian Review of Econometrics","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130059969","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}

To capture the American economy case, we assume that unskilled labor in the manufactured goods sector is unionized, and that sector is intensive in skilled labor, and that trade liberalization increases the relative price of manufactured goods. In the HOS model, trade liberalization induces a reallocation of production towards the sector that uses intensively the country's most abundant factor. The resulting change in relative labor demand impacts wage bargaining in the unionized sector, which, in turn, has a dampening e ect on the Stolper- Samuelson e ect. Moreover, wages of unionized workers are even less responsive to trade liberalization. Through traditional mandated-wages regressions, we show that skilled-wage diferentials changes were less pronounced among more unionized sectors in the U.S. economy for the 1979-1990 period.","PeriodicalId":332423,"journal":{"name":"Brazilian Review of Econometrics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115407264","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}

To this end, we examine 177 local and 119 international bond issuances of 31 Brazilian non-financial companies from January 2004 to April 2013.

Differently from residential customers, industries in Brazil, in addition to purchasing energy and capacity, also face a tariffmenu with Time of Use pricing. Each item in this menu also has different components and price discrimination structure. All these characteristics pose an empirical problem that, so far, has not been faced together in the literature. This methodology was applied in a non-experimental micro data sample of 646 large Brazilian industrial customers (with demands over 300 KW) between January 2002 and December 2006. The results indicate demands for the various services (capacity and energy, separated between peak and non-peak hours) are price elastic, and at least in the AZUL tariff, there is complementarity between energy and capacity in the different periods. Thus, policies on tariff structures based on assumptions of an inelastic aggregate electricity demand could have effects that are quite different from what was intended.","PeriodicalId":332423,"journal":{"name":"Brazilian Review of Econometrics","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129008858","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}
