Public in-kind provision in education, healthcare, or cultural amenities accounts for a large share of government spending, even though redistribution can be achieved with cash transfers and externalities addressed with subsidies. We propose a new efficiency-based rationale for in-kind provision of goods, grounded in two empirically relevant features: (i) these goods are luxuries, with consumption rising more than proportionally with income; and (ii) they generate externalities that depend not only on the total level of consumption but also on its distribution across households. In a tractable heterogeneous-agent model, we show that when these two conditions hold, direct in-kind provision is welfare-improving, even when cash transfers and subsidies are available. Using household- and country-level data, we document that most publicly provided goods exhibit both features. Embedding these insights into a calibrated model for France, we find that optimal fiscal consolidation should reduce subsidies rather than direct provision, and that income-targeted in-kind benefits can generate substantial fiscal savings. Finally, we develop a welfare-based imputation method for in-kind benefits, yielding a more accurate assessment of the distributive impact of government spending.

The distributive effects of carbon taxation are critical for its political acceptability and depend on both income and geographic factors. Using French administrative data, household surveys, and matched employer-employee records, we document that rural households spend 2.8 times more on fossil fuels than urban households and work in firms that emit 2.7 times more greenhouse gases. We incorporate these facts into a spatial heterogeneous-agent model with migration, housing and wealth accumulation, bridging spatial and macroeconomic approaches. Carbon taxes generate 56% larger welfare losses for rural households than for urban households. While uniform or income-based rebates reduce inequality along the income dimension, they leave large spatial disparities that must be offset through location-based transfers. These results suggest that carbon policies should account for spatial differences to improve political feasibility.

What are the effects of central bank balance sheet expansion, and should we worry about central bank losses? Using a Heterogeneous-Agent New Keynesian model incorporating money in utility and an endogenous zero lower bound (ZLB), we study the fiscal-monetary interactions of central bank balance sheet policies. We find that the overall efficiency of asset purchase programs depends on the combination of the expected future size of the balance sheet and the fiscal transmission of central bank losses. First, permanent balance sheet expansions stimulate the economy in the long run and by anticipation, increase inflation and output during the ZLB episode, as they interact with distortionary taxes and imperfect capital markets. Second, upon exiting the ZLB, the central bank incurs losses; issuing securities to offset these losses is more welfare-enhancing than raising taxes.
