Suppose each agent i is assigned a positive weight ai. For every allocation x, define the welfare of x as the weighted sum of utilities of all agents in x: Let xa be an allocation that maximizes the welfare over all allocations: It is easy to show that the allocation xa is Pareto-efficient: since all weights are positive, any Pareto improvement would increase the sum, contradicting the definition of xa. WebIn many one-good economies, Pareto weights aren’t stable. Eventually one agent consumes everything. One of the insights of Colacito and Croce (2013) is that home bias and …

Web1 Apr 2024 · We calibrate the Pareto weights for which the pre-pandemic tax-transfer systems are optimal. Then we ask how the optimal progressivity of the tax-transfer system should change due to COVID-19 induced fiscal pressure given these welfare weights. We start the paper with a refresher about optimal nonlinear income taxation.
