This paper assesses that participation of countries in IMF programs significantly diminishes their vulnerability to external shocks. Currently, one of the primary purposes of the IMF is to ensure global stability. As such, the Fund has the responsibility of advising member countries on the...

In this paper we extend the Bayesian Proxy VAR to incorporate time variation in the parameters. A Gibbs sampling algorithm is provided to approximate the posterior distributions of the model's parameters. Using the proposed algorithm, we estimate the time-varying effects of taxation shocks in...

This paper extends the canonical model of epidemiology, the SIRD model, to allow for time-varying parameters for real-time measurement and prediction of the trajectory of the Covid-19 pandemic. Time variation in model parameters is captured using the generalized autoregressive score modeling...

This paper explores a semiparametric version of a time-varying regression, where a subset of the regressors have a fixed coefficient and the rest a time-varying one. We provide an estimation method and establish associated theoretical properties of the estimates and standard errors in extended...

We develop a dynamic factor model with time-varying parameters and stochastic volatility, estimate it with several variables for a large number of countries and decompose the variance of each variable in terms of contributions from uncertainty common to all countries (global uncertainty),...

The paper examines the processes underlying economic fluctuations by investigating the volatility moderation of U.S. economy in the early 1980's. We decompose the volatility decline using a dynamic factor framework into a common stochastic trend, common transitory component and idiosyncratic...

In this paper, we add to the literature on the assessment of how well RBC simulated data reproduce the dynamic features of historical data. In particular, we evaluate a variety of new Keynesian DSGE models, including the standard sticky price model discussed in Calvo (1983), the sticky price...

In this paper we construct output gap and inflation predictions using a variety of DSGE sticky price models. Predictive density accuracy tests related to the test discussed in Corradi and Swanson (2005a) as well as predictive accuracy tests due to Diebold and Mariano (1995) andWest (1996) are...

In this paper we take an agnostic view of the Phillips curve debate, and carry out an empirical investigation of the relative and absolute efficacy of Calvo sticky price (SP), sticky information (SI), and sticky price with indexation models (SPI), with emphasis on their ability to mimic...

Using data on product-level prices matched to the producing firm's unit labor cost, we reject the hyptothesis of a full and immediate pass-through of marginal cost. Since we focus on idiosyncratic variation, this does not fit the predictions of the Maćkowiak and Wiederholt (2009) version of the...
