This paper evaluates the macroeconomic effects of the European Central Bank's (ECB) Expanded asset purchase programme (APP) on Latvia and other euro area jurisdictions and investigates the crossborder transmission mechanism. To that end, we employ two different vector autoregressive (VAR) models, namely a bilateral structural VAR with block exogeneity (BSVAR-BE) and a multicountry mixed cross-section global VAR with stochastic volatility (MCS-BGVAR-SV). We find that the APP had a limited and weakly significant impact on Latvia's output while the effect on inflation has been robust due to depreciation of the euro. Regarding other jurisdictions, results suggest that the ECB's asset purchases had a larger impact on industrial production in the countries where it drove down long-term interest rates the most via portfolio rebalancing channel. Despite that, our evidence suggests that the APP was mainly transmitted to inflation via exchange rate depreciation rather than through aggregate demand-driven shifts in the Phillips curve.

This paper empirically evaluates the macroeconomic effects of the European Central Bank's (ECB) forward guidance (FG) on the euro area economy and analyses its interaction with asset purchases. To that end, we employ a battery of structural vector autoregressions (SVARs) with both constant and time-varying parameters and/or the error covariance matrix to explore the propagation of the FG shock over time and account for the changing nature of the ECB's FG (Odyssean since July 2013, Delphic prior to that). The FG shock is identified via both traditional sign and zero restrictions of Arias et al. (2014) and narrative sign restrictions of Antolin-Diaz and Rubio-Ramírez ( 2018) which allow us to incorporate additional information about the timing of the shock to sharpen the inference. We find that the ECB's FG on interest rates has been an effective policy tool as its announcement causing a 5 bps drop in interest rate expectations increases output by 0.09%-0.12% and the price level by 0.035%. In addition, multiple evidence suggests that the introduction of the expanded asset purchase programme (APP) in 2015 considerably enhanced the FG credibility. Regarding the transmission mechanism, we find that FG significantly lowered uncertainty in the euro area as well as borrowing costs for both households and firms.
