The paper is concerned with determinacy in a version of the New-Keynesian model that integrates imperfect competition and nominal price and wage setting on goods and labour markets. The model is reformulated with an explicit period of arbitrary length and shown to remain well-defined as the...

This paper estimates the Brazilian NAILO (Nonaccelerating Inflation Level of Output), obtains (Bayesian) probability bands for the Nailo and for its growth rate, and investigates the relationship between deviations of output with respect to the Nailo and the acceleration of inflation. As...

As GDP is highly correlated with both entering and exiting firms, we develop a totally microfounded DSGE model with endogenous firms entry as well as exit decisions. We show that the simplifying assumption of a constant firms' death rate made by the recent literature on DSGE modelling can lead...

In a small-scale New-Keynesian model with a hybrid Phillips curve and IS equation, the paper is concerned with an arbitrary frequency of the agents’ synchronized decision making. It investigates the validity of a fundamental methodological precept according to which no substantive prediction...

We estimate a VAR model of the Phillips curve with an exchange rate shock to the Brazilian economy. Several different specifications, with different time frequencies, were estimated. Overall the results were robust to these changes, and can be summed up in the following: i) the pass-through to...

The goal of this article is to estimate the New Keynesian Phillips Curve for Brazilian economy. Due to some specifications problems in regressions estimated by IV method, the GMM-HAC methodology was used in order to address them. We noted the robustness of the results performing a detailed...

We estimate the Phillips curve with an exchange rate shock to the Brazilian economy. Besides panel data, we estimate the Phillips curve by time series methodology, including Bayesian techniques and Smoothing Transition Regressions (STR) model. The econometric results show three important...

This paper reports the results of estimating a Markov-Switching New Keynesian (MSNK) model using Bayesian methods. The broadest and best fitting MSNK model is a four-regime model allowing independent changes in the regimes governing monetary policy and the volatility of the shocks. We use the...
