We evaluate Germany's temporary value-added tax (VAT) rate reduction as a tool to stimulate consumer spending during the Covid-19 pandemic using a comparative case study approach. We construct a credible counterfactual for Germany in a two-step procedure. First, we carry out a careful...

Die fortschreitende Digitalisierung und die zunehmende Popularität digitaler Zahlungsmöglichkeiten haben zu gravierenden Veränderungen im Zahlungsverhalten geführt. Als Konsequenz erörtert die EZB zurzeit die Einführung eines digitalen Euros. Vorteile bestehen in der Erweiterung...

We propose a novel dynamic mixture vector autoregressive (VAR) model in which timevarying mixture weights are driven by the predictive likelihood score. Intuitively, the state weight of the k-th component VAR model in the subsequent period is increased if the current observation is more likely...

Research and public interest on economic inequality have grown over the last years. Family firms and the concentration of wealth and power in the hands of a few wealthy business families have been discussed as both a cause and a consequence of economic inequality. Yet, so far, we lack knowledge...

In this paper, we analyze whether the complexity of tax bills affects financial markets. Based on the Flesch-Kincaid grade level of the 32 tax bills identified by Romer and Romer (2010) in the period 1962-2003, we assess the relationship between tax bills' complexity and financial markets using...

A frequently employed argument against imposing international sanctions is that rival superpowers are likely to bust sanctions to simultaneously shield the target, harm the sender, and make a profit. We evaluate the legitimacy of this concern by studying the effect of US sanctions on trade flows...

Recursively identified vector autoregressive (VAR) models often lead to a counterintuitive response of prices (and output) shortly after a monetary policy shock. To overcome this problem, we propose to estimate the VAR parameters under the restriction that economic theory is not violated, while...

Since the Russian invasion of Ukraine on February 24, 2022, the West has been intensively discussing its support strategy. Hawkish positions of strengthening Ukraine via armaments, financial resources, and sanctions against Russia compete with dovish views of avoiding further escalation of the...

We examine the asymmetric impact of shocks to macroeconomic expectations and their underlying dispersion on equity risk premia across different market regimes. First, we rely on a two-state logit mixture vector autoregressive model and use Consensus Economics survey data on GDP growth,...

Firms often struggle with the successful commercialization of innovations, and there is a need for reliable predictors. Prior research suggests that intellectual property (IP) rights play a key role in the commercialization of innovations. However, to what extent can IP rights be used to predict...
