Implementing a minimum exchange rate regime by buying foreign currency eases monetary conditions domestically and may thus have a direct impact on the inflation rate. However, such foreign currency purchases involve a risky expansion of the central bank’s balance sheet total. A new model can now predict what expansion of the balance sheet a central bank must expect if it wishes to implement a minimum exchange rate in the foreign exchange market.

Climate change is a global challenge that requires international policy coordination. This conclusion is also borne out in a recent study on the macroeconomics implications of carbon pricing. Several different scenarios are considered – different regions introduce carbon pricing schemes unilaterally or in cooperation, and in the presence or absence of border adjustment schemes.

As a response to the Covid-19 pandemic, parents in Germany received a series of transfer payments from the state in 2020 and 2021. This so-called child bonus (“Kinderbonus”) amounted to a total of €450 per child. A new study finds that the child bonus led to only a slight increase in household spending. Therefore, the child bonus should be seen less as a fiscal stimulus measure and more as an instrument of redistribution from the general population to families.

Are individuals concerned enough about climate change to change their behavior and bear additional costs as a consequence? How can they be motivated to fight climate change? A Bundesbank survey conducted between April 2020 and December 2021 shows that people are more concerned about climate change than about the state of the economy. During most of the ongoing pandemic, only the coronavirus was of a higher concern. While people who rate climate change as a serious issue are also more willing to take on additional costs to help fight climate change, providing information on ways to reduce carbon emissions further increases their willingness to do so.

The rate of inflation has a bearing on the relative price of individual products and therefore on demand for those products. Using new micro price data, we investigate how high the optimal inflation rate must be to prevent relative product demand from being distorted. Contradicting a common claim, we find that the optimal rate is not zero for a large part of the euro area, but is, in fact, clearly in positive territory.
