On the Optimality of Differential Asset Taxation
How should a utilitarian government balance redistributive concerns with the need to provide incentives for business creation and investment? Should they tax business profits, the (risk-free) savings of owners, or some combination of both? To address this question, this paper presents a model in which the desirability of differential asset taxation emerges endogenously from the presence of agency frictions. I consider an environment in which entrepreneurs hire workers and rent capital to produce output subject to privately observed shocks and have the ability to both divert capital to private ...

Relationship lending in the interbank market and the price of liquidity
We empirically investigate the effect that relationship lending has on the availability and pricing of interbank liquidity. Our analysis is based on a daily panel of unsecured overnight loans between 1,079 distinct German bank pairs from March 2006 to November 2007, a period that includes the 2007 liquidity crisis that marked the beginning of the 2007/08 global financial crisis. We find that (i) relationship lenders are more likely to provide liquidity to their closest borrowers, (ii) particularly opaque borrowers obtain liquidity at lower rates when borrowing from their relationship lenders, ...

Top Income Concentration and Volatility
Measures of income concentration?such as the share of income received by the highest income families?may be biased by pro-cyclical volatility in annual income. Permanent income, though, can smooth away such volatility and sort families by their usual economic resources. Here, we demonstrate this bias using rolling 3-year panels of IRS tax records from 1997 to 2013 as a proxy for permanent income. For example, one measure of 2012 income concentration?the share of income received by the top 0.1 percent?falls from 11.3 percent to 8.9 percent when families are organized by permanent income ...

Risk Management for Sovereign Debt Financing with Sustainability Conditions
We develop a model of debt sustainability analysis with optimal financing decisions in the presence of macroeconomic, financial and fiscal uncertainty. We define a coherent measure of refinancing risk, and trade off the risks of debt stock and flow dynamics, subject to debt sustainability constraints and endogenous risk and term premia. We optimize both static and dynamic financing strategies, compare them with several simple rules and consol financing to demonstrate economically significant effects of optimal financing, and show that the stock-flow tradeoff can be critical for ...

The Optimal Taxation of Business Owners
Business owners in the United States are disproportionately represented among the very wealthy and are exposed to substantial idiosyncratic risk. Further, recent evidence indicates business income primarily reflects returns to the human (rather than financial) capital of the owner. Motivated by these facts, this paper characterizes the optimal taxation of income and wealth in an environment where business income depends jointly on innate ability, luck, and the accumulated past effort exerted by the owner. I show that in (constrained) efficient allocations, more productive entrepreneurs ...

The Optimal Taxation of Business Owners
Business owners in the United States are disproportionately represented among the wealthy and are exposed to substantial idiosyncratic risk. Further, recent evidence indicates that business income primarily reflects returns to the human capital of the owner. Motivated by these facts, this paper characterizes stationary efficient allocations and optimal linear taxes on income and wealth when business income depends on innate ability, luck, and the past effort of the owner. I first show that in stationary efficient allocations, more productive entrepreneurs typically bear more risk and the ...

The Welfare Cost of Business Cycles with Heterogeneous Trading Technologies
The author investigates the welfare cost of business cycles in an economy where households have heterogeneous trading technologies. In an economy with aggregate risk, the different portfolio choices induced by heterogeneous trading technologies lead to a larger consumption inequality in equilibrium, while this source of inequality vanishes in an economy without business cycles. Put simply, the heterogeneity in trading technologies amplifies the effect of aggregate output fluctuation on consumption inequality. The welfare cost of business cycles is, therefore, larger in such an economy. In the ...

Financial life after the death of a spouse
The death of a spouse results in a considerable decline in average income for the surviving spouse. The Social Security survivors benefits program compensates the surviving spouse, most often a woman, for almost all of the lost income, allowing them to work less, but many widows who are not yet eligible for the program struggle to meet their financial needs.

Misallocation and Intersectoral Linkages
We analytically characterize the aggregate productivity loss from allocative distortions in a setting that accounts for the sectoral linkages of production. We show that the effects of distortions and the role of sectoral linkages depend crucially on how substitutable inputs are. We find that the productivity loss is smaller if input substitutability is low. Moreover, with low input substitutability, sectoral linkages do not systematically amplify the effects of distortions. In addition, the impact of the sectors that supply intermediate inputs becomes smaller. We quantify these effects in ...
