This paper develops a quantitative spatial general equilibrium model for the German economy to address two issues. First, we explore the role of commuting for local labor markets and their capacity to absorb productivity shocks. Second, we address the role of housing markets for quantitative...

This paper develops a model with an endogenous number of cities to explore whether local governments establish the optimal city size when key activities in the city are associated with emissions that harm consumers. In contrast to extant research, our model is fully micro-founded with respect to...

This paper shows that subsidy competition may be efficiency enhancing. We model a subsidy game among two asymmetric regions in a new trade model, where capital can freely move among regions, but capital rewards are repatriated. We study subsidy competition, starting from an equilibrium where the...

The paper compares non-cooperative commodity taxation under the destination and origin principles under a variety of different assumptions about market structure. We consider a model of international duopoly with either quantity or price competition of firms and either segmented or integrated...

We analyze non-cooperative commodity taxation in a symmetrictwo-country trade model characterized by monopolisticcompetition and international firm and capital mobility. In thissetting, taxes in one country affect foreign welfare through therelocation of mobile firms and through changes in the...

This paper explores the macroeconomic consequences of regulatory barriers in housing markets. We take a European perspective, allowing us to offer novel facts, theory, and methodology. Our focus is on Germany, a compelling case exemplifying key characteristics unique to European city systems. To...

Recent disruptions to global value chains (GVCs) have raised an important question: Can decoupling from GVCs increase a country’s welfare by reducing its exposure to foreign supply shocks? We use a quantitative trade model to simulate GVCs decoupling, defined as increased barriers to global...

In early 2020, the disease Covid-19 caused a drastic lockdown of the Chinese economy. We use a quantitative trade model with input-output linkages to gauge the effects of this adverse supply shock in China on the global economy through international trade and global value chains (GVCs). We find...

This paper characterizes equilibrium properties of a broad class of economic models that al-low multiple heterogeneous agents to interact in heterogeneous manners across several markets. Our key contribution is a new theorem providing sufficient conditions for uniqueness and stability of...
