In our analytical general equilibrium model where two polluting inputs can be substitutes or complements in production, we study the effects of a tax on one pollutant in two cases: one where both pollutants face taxes and the second where the other pollutant is subject to a permit policy. In...

Although firms may face radically different production conditions, this dimension of firm heterogeneity is often overlooked. We model input demand across local factor markets, explicitly considering search costs which explain why firms care about both the price and availability of inputs. The...

A rapidly rising carbon tax leads to faster extraction of fossil fuels and accelerates global warming. We analyze how general equilibrium effects operating through the international capital market affect this Green Paradox. In a two-region, two-period world with identical homothetic preferences...

We develop a unifying framework for optimal income taxation in multi-activity economies with general production technologies. Agents are characterized by an N-dimensional skill vector that captures intrinsic abilities in N activities. The private return to each activity depends on individual...

This paper explores the economic impacts of preferential trade agreements, conditional on their level of ambition. We cluster 278 agreements, encompassing 910 provisions over 18 policy areas and estimate the trade elasticity for the different clusters. We then use these elasticities in a series...

This paper proposes a novel approach to evaluate location decisions for public facilities. The approach addresses, not only the standard distance-minimizing problem, but also the endogenous location decisions of individuals. To do so, I develop a quantifiable general equilibrium model with...

The tractable general equilibrium model developed by Golosov et al. (2014), GHKT for short, is modified to allow for additional negative impacts of global warming on utility and productivity growth, mean reversion in the ratio of climate damages to production, labour-augmenting technical...

This paper studies how linear tax and education policy should optimally respond to skill-biased technical change (SBTC). SBTC affects optimal taxes and subsidies by changing i) direct distributional benefits, ii) indirect redistributional effects due to wage-(de)compression, and iii) education...

It is well recognized that there emerged a trend of inward looking trade policies even before COVID pandemic crippled the world. These were reflected in both BREXIT and US-China trade conflict. As countries become inward oriented, usually local prices start rising. With this backdrop this paper...

This paper explores the implications on trade and wage inequality of introducing financial capital or credit in the standard Ricardian model of production, where a given amount of start-up credit is used to employ sector specific skilled and unskilled workers following the Wage Fund approach of...
