Consumer products and services can often be described as mixtures of ingredients. Examples are the mixture of ingredients in a cocktail and the mixture of different components of waiting time (e.g., in-vehicle and out-of-vehicle travel time) in a transportation setting. Choice experiments may...

Corruption, vote buying, and other sensitive topics are difficult to study because people tend to under-report them in surveys. The degree of under-reporting bias has been shown to vary across studies, contexts, and question structures, but no systematic explanation for the variation has been...

In this work we present a new method for Quickest Change Detection (QCD) and Quickest Hub Discovery (QHD) in correlation structures that geometrically represents solutions from asymptotic Random Matrix theory (RMT) consistently, and allows to incorporate new distance metrics for both tests. We...

We use a large-scale representative survey of households from October 19-21 that elicits respondents’ expectations about the presidential election’s outcome as well as their economic expectations to document several new facts. First, people disagreed strongly about the likely outcome of the...

We use a representative online survey to investigate the inflation expectations of German consumers and the credibility of the ECB's inflation target during the recent high inflation period. We find that credibility has trended downwards since summer 2021, reaching an all-time low in April 2022....

We use novel survey data to study firms’ inventory contracts. We document facts about the usage of purchase and sale contracts. We find that firms purchase and sell inventory through three contractual arrangements: fixed price and quantity, fixed price only, and fixed quantity only. The former...

What inflation measure should central banks target? This paper shows optimal monetary policy targets headline inflation if households pay limited attention to different consumption categories when forming inflation expectations. This result stands in contrast to standard rational expectations...

We present the results of an experiment where a random subset of the participants in the Bundesbank's household panel receive personalized response scales, centered at each participant's point forecast. Personalized response scales offer two advantages over the standard scale which is centered...

We use data from a large panel survey of UK firms to analyze the economic drivers of price setting since the start of the Covid pandemic. Inflation responded asymmetrically to movements in demand. This helps to explain why inflation did not fall much during the negative initial pandemic demand...
