This paper discusses efficiency considerations underlying the widespread exemption of food from sales and value added taxes, in contrast to the distributional considerations usually used to justify them, analyzing the implications for tax policy. Although there are increasing returns in both...

We develop a general equilibrium tax model to evaluate the impacts of equal yield base broadening in indirect taxes from high rate narrow based (typically manufactures) taxes to broad based taxes (including services) such as a VAT. We capture differences in choice of mode of supply between...

Available studies on asymmetries in the monetary transmission mechanism within Europe are invariably based on macro-economic evidence: such evidence is abundant but often contradictory. This paper takes a different route by using micro-economic data. We use the information contained in the...

We use a detailed micro dataset on product availability to construct a direct high-frequency measure of consumer product shortages during the 2020-2021 pandemic. We document a widespread multi-fold rise in shortages in nearly all sectors early in the pandemic. Over time, the composition of...

This technical report presents the dynamic microsimulation model microWELT-US developed for US labour force projections accounting for education and health. microWELT-US is the adaptation of an existing microsimulation model for Europe. The microsimulation model supports a comparative analysis...

We evaluate the impact of government mandated proof of vaccination requirements for access to public venues and non-essential businesses on COVID-19 vaccine uptake. We find that the announcement of a mandate is associated with a rapid and significant surge in new vaccinations (more than 60\%...

It has often been asserted that imposition of environmental regulations in the 1970's may be a partial explanation for the productivity growth slowdowns experienced by most industrialized countries during that decade.The contention is that expenses incurred to satisfy these regulations, such as...

Many households hold little wealth, especially liquid wealth. In precautionary savings models, absent preference heterogeneity, these households should display not only higher marginal propensities to consume (MPCs), but also lower average propensities to consume (APCs) and higher future...

This paper studies household financial choices in four euro area countries. The goal of the analysis is to understand the sources of the differences in these choices and their implications for the impact of monetary policy on consumption. The estimation of key parameters uses a simulated method...

This note lays out the basic Susceptible-Infected-Recovered (SIR) epidemiological model of contagion, with a target audience of economists who want a framework for understanding the effects of social distancing and containment policies on the evolution of contagion and interactions with the...
