RESUMO Para entender os aspectos macroeconômicos da inflação, é necessário investigar o que acontece no nível microeconômico. A inflação afeta substancialmente a interação microeconômica entre empresas e consumidores. As empresas escolhem regras de preços que afetam a pesquisa dos consumidores. A pesquisa é realizada nas empresas e no tempo. A teoria não fornece uma resposta clara ao efeito da inflação no bem-estar. Por um lado, devido aos custos de ajuste, uma inflação mais alta está associada a uma maior dispersão de preços, tornando a busca mais atraente. Por outro lado, deteriora o conteúdo de informações dos preços, reduzindo a capacidade dos consumidores de aproveitar a pesquisa. Este artigo examina as contribuições muito recentes para esse campo. Argumenta que, embora possamos obter informações importantes desses artigos, nenhum deles fornece uma resposta satisfatória à pergunta que intriga os macroeconomistas há mais de duas décadas: como explicar os custos sociais da inflação?

In this paper, we build a framework where the interplay between the lobby power of special interest groups and the voting power of the majority of the population leads to political business cycles. We apply our setup to explain electoral cycles in government expenditure composition, aggregate expenditures, and real exchange rates.

We extend the macroeconomic literature on Ss‐type rules by introducing infrequent information in a kinked adjustment‐cost model. We first show that optimal individual decision rules are both state and time dependent. We then develop an aggregation framework to study the macroeconomic implications of such optimal individual decision rules. In our model, a vast number of agents act together, and more so when uncertainty is large. The average effect of an aggregate shock is inversely related to its size and to aggregate uncertainty. These results contrast with those obtained with full information adjustment cost models. JEL Classification: E0,E1,E2,E3 Les effets macroéconomiques de l'information infréquente quand il y a des coûts d'ajustement. Les auteurs étendent la portée de la littérature spécialisée sur les règles de type Ss en proposant des postulats d'information infréquente et de fonction de coûts d'ajustement pliée. On montre que les règles de décision optimales des individus dépendent à la fois de l'état de l'environnement et du moment. On développe alors un cadre d'agrégation pour étudier les impacts macroéconomiques de ces règles optimales de décision. Dans ce modèle, un grand nombre d'agents agissent de concert, et optimales ce d'autant plus que l'incertitude s'accroît. L'effet moyen d'un choc au niveau global est inversement reliéà son importance et au niveau d'incertitude agrégée. Ces résultats contredisent ceux qu'on obtient dans des modèles de coûts d'ajustement avec pleine information.

We investigate the relation between existing fiscal rules and investments in the context of a fiscal crisis in Brazil. We analyze existing fiscal rules at national and subnational levels, their enforcement, and proposed alternatives. Using narrative analysis, case studies, interviews, empirical estimation, and model simulations, we conclude that public investment is not closely related to fiscal rules in Brazil but is mainly determined by fiscal conditions both at national and subnational (state) levels. It is the steady increase of personnel expenditures in real terms that underlies the fiscal deterioration of the last decade, despite the existence of fiscal rules devised to prevent it. We argue that a constitutional rule limiting subnationals personnel expenditures to 50 percent of net revenues, triggering adjustment measures when reaching 47.5 percent, would be an effective instrument for subnational fiscal management, opening fiscal space for increasing investments. At the national level, despite the existence of several fiscal rules, the only effective fiscal anchor is the primary expenditure ceiling introduced in 2016, which has successfully curbed expenditures, including those of the judiciary and legislature.

Government-driven credit played an important role in countervailing the private credit crunch in Brazil during the recent financial crisis. However, government credit concessions continued to expand after the economy recovered. This paper investigates some important features of this expansion using a huge repository of loan contracts between banks and firms, composing an unbalanced panel of almost 1 million firms between 2004 and 2012. The results show that larger, older and less risky firms have benefited most from the government-sponsored credit expansion. Additionally, although higher access to earmarked credit tends to lead to higher leverage, the effect on investment appears to be insignificant for publicly traded firms. Since interest rates on earmarked loans are lower than market interest rates, firms with higher access to this type of loan tend to lower the cost of debt.
