Abstract We evaluate the forecasting performance of four competing models for short-term macroeconomic forecasting: the traditional VAR, small scale Bayesian VAR, Factor Augmented VAR and Bayesian Factor Augmented VAR models. Using Armenian quarterly actual macroeconomic time series from 1996Q1 – 2014Q4, we estimate parameters of four competing models. Based on the out-of-sample recursive forecast evaluations and using root mean squared error (RMSE) criterion we conclude that small scale Bayesian VAR and Bayesian Factor Augmented VAR models are more suitable for short-term forecasting than tra

Small-sample properties of bootstrap cointegration rank tests for unrestricted panel VAR process are considered when long-run cross-sectional dependencies occur. It is shown that the bootstrap cointegration rank tests for the panel VAR model based on levels canonical correlation analysis are oversized, whereas the bootstrap cointegration rank tests based on maximum likelihood framework are undersized. Moreover, the former tests are in general outperformed by the latter in terms of performance. The results of the investigation indicate that the ML-based bootstrap cointegration rank tests perfor

In this paper the theory on the estimation of vector autoregressive (VAR) models for I(2) processes is extended to the case of long VAR approximation of more general processes. Hereby the order of the autoregression is allowed to tend to infinity at a certain rate depending on the sample size. We deal with unrestricted OLS estimators (in the model formulated in levels as well as in vector error correction form) as well as with two stage estimation (2SI2) in the vector error correction model (VECM) formulation. Our main results are analogous to the I(1) case: We show that the long VAR approxima

This paper examines whether forecasting CPI components improves CPI forecast. We exploit quarterly data for Poland, disaggregated into 12 components. We follow methodology used in previous studies for Euro Area (Hubrich, 2005; Reijer and Vlaar, 2006). AR, MA, TAR and unrestricted VAR models are estimated using recursive sample and aggregated into CPI. Using out-of-sample forecasts, these models are evaluated and compared to the benchmark -- equivalents for aggregate CPI. The evidence is mixed. VAR component-forecast outperform benchmark. Contrary to VAR, for AR and TAR models we do not find su

We prove that local projections (LPs) and Vector Autoregressions (VARs) estimate the same impulse responses. This nonparametric result only requires unrestricted lag structures. We discuss several implications: (i) LP and VAR estimators are not conceptually separate procedures; instead, they are simply two dimension reduction techniques with common estimand but different finite‐sample properties. (ii) VAR‐based structural identification—including short‐run, long‐run, or sign restrictions—can equivalently be performed using LPs, and vice versa.

In this paper we investigate the impact of corruption on economic growth in Portugal over the period 1980-2018. The empirical approach makes use of a VAR model inspired by the standard Cobb-Douglas aggregate production function. The VAR model includes the capital stock, hours worked, total factor productivity and the corruption perceptions index (CPI) of Transparency International. The CPI combines several sources of information on the level of corruption in each country. The scale of this index goes from 0, the highest level of corruption, to 10, the lowest level.

This study was aimed at investigating the effects of energy prices on inflation in South Africa. This was achieved by means of econometric analysis and annual time series data spanning from 1994 to 2020. The findings revealed that electricity tariffs and petrol prices exhibit a positive effect on inflation in South Africa. On the contrary, interest rates and the exchange rate as control variables were found to have a negative effect on the inflation rate. The impulse response function indicated that inflation responds positively to innovations in petrol prices, electricity tariffs and money su

The results we reported are tainted by the omission of two factors: the Jacobians induced by the mapping of our priors over VAR parameters β into the restricted sample spaces relevant under hypotheses H2-H4 (hence, tainting our calculations of p(Hi|y,X) in (22) for i = 2–4), and an integrating constant

Abstract Up to this point we have analysed just one set of variables representing a broadly formulated money market model. The unrestricted VAR model estimated at the first stage of the analysis was just a convenient reformulation of the covariances of the data, and bore little resemblance to the underlying economic model. By systematically imposing more and more, statistically acceptable, restrictions on the VAR, we were able to uncover economically meaningful structures in the data. Such a procedure is called general-to specific modelling. However, some of the findings were consistent with o

Abstract When the empirical model is estimated with data that are non-stationary in levels, we need to discuss two different identification problems: identification of the long-run structure (i.e. of the cointegration relations) and identification of the short-run structure (i.e. of the equations of the system). The former is about imposing long-run economic structure on the unrestricted cointegration relations, the latter is about imposing short run dynamic adjustment structure on the equations for the differenced process.

Abstract Most real business cycle models have been assessed by studying the correspondence of their predictions to a set of stylised facts. This paper argues that such tests are not extensive enough and proposes to evaluate the models using standard econometric procedures. Specifically it is argued that these models should be studied by eliciting the restricted VAR representation underlying them and comparing it with the VAR estimated in an unrestricted way from the underlying data. Allowance is made for cases where the driving forces are integrated and when they are stationary. When forces su

Besides VAR estimation, IRFs are computed to define how variables react to certain shocks.

This logic embeds into a corresponding modal first-order logic S5-FOL.
