The shocks in structural vector autoregressive (VAR) analysis are typically assumed to be instantaneously uncorrelated. This condition may easily be violated in proxy VAR models if more than one shock is identified by a proxy variable. Correlated shocks may be obtained even if the proxies are...

I develop and analyze a monetary model with liquid equity. Equity is a claim on the profits of firms acting as sellers in the search-and-matching market. Buyers in that market devote search to obtain matches with firms, and use the equity to relax a liquidity constraint. The dual nature of...

This study shows that, in a model with non-separable preferences for durable and non-durable goods, the effect of relative prices on the ratio of consumption for the two goods, known as the intratemporal elasticity of substitution, has decreased in the U.S. since 1981. We found that durable and...

We employ a structural VAR model with global and US variables to study the relevance and transmission of oil, food commodities, and industrial input price shocks. We show that commodities are not all alike. Industrial input price changes are almost entirely endogenous responses to other shocks....

Die politische Diskussion um die deutsche Schuldenbremse klingt nicht ab. Nicht zuletzt dürften die Verhandlungen über den Bundeshaushalt des Jahres 2025 ihren Teil dazu beigetragen haben. Im Grunde kritisieren zu einem erheblichen Teil dieselben Personen die Schuldenbremse mit denselben...

In recent times, interest in currency boards has come back into vogue as a tool to stabilize the nominal exchange rate and accelerate the process of economic stabilization. The most important reasons for the renewed interest in currency boards must be found in the need to face the persistent...

Prior research has documented that attention to inflation shifts when inflation surpasses a 3-4% threshold. In this note we examine how attention to inflation declines in episodes of disinflation. We show that for countries where inflation has returned to "normal" (pre-threshold) levels,...

Die Modern Monetary Theory (MMT) ist ein neuer postkeynesianischer Ansatz, der von prominenten linken Politikern unterstützt wird. Aktuell gewinnt er vor allem in den USA an Einfluss. Die MMT geht davon aus, dass eine Regierung, die in ihrer eigenen Währung Kredite aufnimmt, nicht...

Das Eurosystem hat bis Dezember 2018 im Rahmen des Public Sector Purchase Programme (PSPP) Staatsanleihen für fast 2,2 Billionen Euro erworben, um (laut offizieller Begründung) die Inflationsrate auf den Zielwert von knapp 2 % zu bringen. Nicht wenige Ökonomen qualifizieren die Anleihekäufe...
