Motivated by the fiscal policy measures taken by euro zone governments during the 2021/2022 energy crisis, we examine their ability to counter inflationary surges resulting from energy price hikes in energy-importing economies. We use a calibrated small-open economy model in which monetary policy fixes the exchange rate. Subsidies on the sale of energy and on firms’ energy expenditures are among the most effective instruments. They reduce marginal costs and limit the pass-through of the price hike which attenuates inflation and stabilizes output and the current account. While inflation indexation of prices aggravates the adverse effects, it renders consumption tax cuts more effective as they attenuate the shock’s domestic circulation.

We revisit the US weekly economic index (WEI) put forth by Lewis, Mertens, Stock and Trivedi (2021). In a narrow sense, we replicate their main results with data gathered from its original sources. In a wide sense, we apply the methodology established in Wegmüller, Glocker and Guggia (2023) to adjust the weekly input series for seasonal patterns, calendar day effects, and excess volatility. In a long sense, we show that our proposed data adjustment significantly improves the nowcasting performance of the WEI.

We construct a composite index to measure the real activity of the Swiss economy on a weekly frequency. The index is based on a novel high-frequency data set capturing economic activity across distinct dimensions over a long time horizon. We propose a six-step procedure for extracting precise business cycle signals from the raw data. By means of a real-time evaluation, we highlight the importance of our proposed adjustment procedure: (i) our weekly index significantly outperforms a comparable index without adjusted input variables; and (ii) the weekly index outperforms established monthly indicators in nowcasting GDP growth. These insights should help improve other recently developed high-frequency indicators.
