Over the last decades, macro-economists have renewed their efforts to reduce the gap between monetary macroeconomics and real-world central banking. This paper reviews how macroeconomics has since 2016 approached the possible introduction of retail central bank digital currencies (CBDC). A...

We review the recent literature that studies new, detailed micro data on prices. We discuss implications of the new micro data for macro models. We argue that the new micro data are helpful for macro models, but not decisive. There is no simple mapping from the frequency of price changes in...

In this paper we discuss the role of the cross-sectional heterogeneity of beliefs in the context of understanding and assessing macroeconomic vulnerability. Emphasis lies on the potential of changing levels of disagreement in expectations to influence the propensity of the economy to switch...

We introduce an information provision experiment into a standard dynamic rational inattention model. We derive analytical results about how the treatment effect varies with characteristics of the environment and the individual. We use these results to discuss findings in the empirical literature...

We propose a monetary model in which the unemployed satisfy the official US definition of unemployment: they are people without jobs who are (i) currently making concrete efforts to find work and (ii) willing and able to work. In addition, our model has the property that people searching for...

We propose a monetary model in which the unemployed satisfy the offcial US deffinition of unemployment: they are people without jobs who are (i) currently making concrete efforts to find work and (ii) willing and able to work. In addition, our model has the property that people searching for...

Using data on product-level prices matched to the producing firm's unit labor cost, we reject the hypothesis of a full and immediate pass-through of marginal cost. Since we focus on idiosyncratic variation, this does not fit the predictions of the Maćkowiak and Wiederholt (2009) version of the...

This paper investigates a dynamic general equilibrium model with search. In particular, search externalities are reßected by an increasing returns to scale matching function, which may imply an indeterminate equilibrium. Hence, the model is capable to generate business ßuctuations, driven by...

Currently the U.S. is experiencing record budget and current account deficits, a phenomenon familiar from the "Twin Deficits" discussion of the 1980s. In contrast, during the 1990s productivity growth has been identified as the primary cause of the US current account deficit. We suggest a...

We investigate the role of economic transparency within the framework of one of Townsend's models of "forecasting the forecasts of others". The equilibrium has the property that "higher order beliefs"; are coordinated into a finite-dimensional setup that is amenable to address monetary policy...
