No. of bitstreams: 1 ErivamPintoJunior.pdf: 1116751 bytes, checksum: 2155e1eb5a800f430e8378c159cc5e29 (MD5) Previous issue date: 2017-06-22 / CAPES / The cause and effect relationships between the variations in aggregate demand and inflation are distinct and depend on the theoretical approach adopted for the examination of the inflationary process. Excess demand is not always the prime source of inflation. In some cases, the inflation dynamics can be analyzed from some variables that, when generating cost increases, cause an increase in the general level of prices. The conventional approach admits that equilibrium in the labor market is essentially automatic and that inflation is always a consequence of excess demand. From this diagnosis, he concludes that the role of the monetary authority is to control the demand to a level that corresponds to the non-accelerating unemployment inflation rate, through the manipulation of the interest rate. For the Post-Keynesian approach, this view can only be constructed from the idea that money is endogenous and not neutral, which allows one to see inflation not as a result of excess demand, but that the growth of the currency may have been growth of economic costs. On the other hand, the Distributive Conflict approach seeks to understand the inflationary process from the social and political environment of an economy, considering what are the actions and reactions of the various groups that comprise it and the way in which each group takes initiative in the intention to defend income. The formation of the general level of prices occurs in a different way from those that reflect the scarcity of factors of production and from this analysis, the orthodox elements that associate the inflationary process with anenvironment of excess demand is not present. This research presents a theoretical narrative of how the orthodox approach considers that excess or acceleration of demand is capable of causing inflation and, in the face of such a diagnosis, how it should be combated, followed by interventionist discussion, which adds the endogeneity of money in the analysis of the inflationary process and which considers that inflation can occur even before demand reaches the level of full employment. Subsequently, it seeks to delineate the emergence of Structuralist thought, which opposed dominant theories and sought to understand the inflationary dynamics in Latin American countries from their specificities. Such theorists have provided the basis for the approach that is subsequently analyzed, that of Distributive Conflict. For this, the research tries to expose the real cost variables that are used to analyze the inflationary dynamics of an economy in a given time period, then a comparison of how the approaches exposed diverge and converge in relation to the analysis of inflationary dynamics and the mechanisms which must be adopted in pursuit of the equilibrium of the general level of prices. / As relações de causa e efeito entre as variações da demanda agregada e da inflação são distintas e dependem da abordagem teórica adotada para o exame do processo inflacionário. Nem sempre o excesso de demanda é a fonte primeira de inflação. Em determinados casos, a dinâmica inflacionária pode ser analisada a partir de algumas variáveis que, ao gerar aumentos de custos, causam aumento do nível geral de preços. A abordagem convencional admite que o equilíbrio no mercado de trabalho é essencialmente automático e que a inflação é sempre consequência do excesso de demanda. A partir desse diagnóstico, conclui que o papel da autoridade monetária é controlar a demanda para um nível que corresponda à taxa de desemprego não aceleradora da inflação, através da manipulação da taxa de juros. Para a abordagem Pós-Keynesiana, essa visão só pode ser construída a partir da ideia de que a moeda é endógena e não neutra, o que permite enxergar a inflação não como resultante do excesso de demanda, mas que o crescimento da moeda pode ter sido antecedido pelo crescimento dos custos da economia. Por outro lado, a abordagem do Conflito Distributivo busca entender o processo inflacionário a partir do ambiente social e político de uma economia, considerando quais são as ações e reações dos diversos grupos que a compõem e a maneira como cada grupo toma iniciativa na intenção de defender sua participação na renda. A formação do nível geral de preços ocorre de forma distinta daqueles que refletem a escassez de fatores de produção e a partir dessa análise, os elementos ortodoxos que associam o processo inflacionário a um ambiente de excesso de demanda não se faz presente. Esta pesquisa apresenta uma narrativa teórica de como a abordagem ortodoxa considera que o excesso ou a aceleração da demanda é capaz de causar inflação e, diante de tal diagnostico, como ela deve ser combatida, seguida da discussão intervencionista, que adiciona a endogeneidade da moeda na análise do processo inflacionário e que considera que a inflação pode ocorrer mesmo antes da demanda alcançar o nível de pleno emprego. Posteriormente, procura delinear o surgimento do pensamento Estruturalista, que se opôs às teorias dominantes e que buscou entender a dinâmica inflacionária nos países LatinoAmericanos a partir de suas especificidades. Tais teóricos ofereceram as bases para a abordagem que é analisada subsequentemente, a do Conflito Distributivo. Para isso, a pesquisa trata de expor as variáveis reais de custo que são utilizadas para analisar a dinâmica inflacionária de uma economia em determinado período temporal, depois uma comparação de como as abordagens expostas divergem e convergem em relação à análise da dinâmica inflacionária e os mecanismos que devem ser adotados em busca do equilíbrio do nível geral de preços.

External economic shocks cause domestic macroeconomic aggregates to fluctuate. This may call for a macroeconomic policy intervention. Since the early 1990s an increasing number of countries have adopted an inflation targeting framework. In reality, inflation targeters do not have perfect information when determining the interest rate in order to maintain their goal of price stability and stable economic growth. Therefore it is relevant to understand how shocks affect the domestic macroeconomic aggregates theoretically and investigate whether the theoretical predictions hold empirically. I use the New Keynesian model by Clarida, Galí and Gertler from 1999 and investigate explicitly the theoretical effects of expected and unexpected supply and demand-side shocks on the monetary policy instrument and the two monetary policy target variables – the interest rate, output gap and inflation rate. By analysing the impulse-response functions of a structural VAR model applied to quarterly Swedish and British data from 1994 to 2011, I test empirically the theoretical predictions according to the New Keynesian model. I find that the empirical results are in line with the theoretical predictions.

This thesis examines the transmission of monetary policy and the effects of persistent cost-push shocks in the presence of high household indebtedness (DTI) and frictions in fixed-rate mortgage (FRM) interest rates. A dynamic stochastic general equilibrium (DSGE) model incorporating housing, household debt, and long-term FRMs is estimated to accomplish this. The key findings can be summarized as follows: (i) A higher DTI leads to a stronger transmission of monetary policy, although this effect is dampened by the degree of interest rate fixation periods. (ii) Cost-push shocks propagates more strongly to inflation when the interest rate fixation periods is longer, resulting in delayed and slightly muted effects on output and consumption compared to adjustable-rate mortgages (ARM). (iii) While stronger responses to inflation help mitigate the cost-push shock, this comes at the expense of a larger output gap but with a slightly faster stabilization of the economy with a somewhat steeper recovery.
