We study optimal redistributive taxes when the population can be disaggregated into tagged groups. Under reasonable circumstances, the tax system will be more redistributive in the tagged group with the higher proportion of high-ability persons. We extend the analysis to the case where the tag reflects differences in resources required to achieve a given level of utility. The compensation given...

When a user shares her data with online platforms, she reveals information about others. In such setting, externalities depress the price of because once user's is leaked by others, has less reason to protect and privacy. These depressed prices lead excessive sharing. We characterize conditions under which shutting down markets improves welfare. Platform competition does not redress problem exc...

Electric vehicles have a unique potential to transform personal transportation. We analyze this transition with dynamic model capturing falling costs of electric vehicles, decreasing pollution from electricity, and increasing vehicle substitutability. Our calibration the US market shows gasoline is not optimal at current substitutability: production ban would large deadweight loss. At higher su...

We develop a model of political competition with endogenous turnout and platforms. Parties trade off incentivizing their supporters to vote discouraging the competing party from voting. show that latter objective is particularly pronounced for an edge in race. Thus, increase support may lead adoption policies favoring its opponents so as asymmetrically demobilize them. study implications econom...

Support statement: This study was partly supported by a grant to the Diffuse Lung Diseases Research Group from the Ministry of Health, Labour and Welfare, Japan (grant number H23-Nanchi-Ippan-023). M. Sawahata thanks the Japanese Society of Sarcoidosis and Other Granulomatous Disorders for awarding the Grant for Young Investigators (2013), and Jichi Medical University for awarding the JMU Gradu...

A government designs transfers to agents in the absence of information on their preferences. The second-best allocation is equal sharing among citizens when the awards are deterministic. We provide a necessary and su cient condition under which lotteries improve upon the egalitarian outcome. The condition requires that the citizens with large social weights have low risk aversion, and that the ...

The paper studies the dynamic macroeconomic and welfare effects of tax policy in the context of an overlapping-generations model of the Yaari-Blanchard type for a closed economy. The model is extended to allow for endogenous labor supply and three tax instruments—namely, a capital tax, labor income tax, and consumption tax. It is shown that labor taxes increase welfare of old generations wherea...

This article analyzes concerns about market power and inequality in a model with multiple sectors, heterogeneous abilities, endogenous labor supply, nonlinear income taxation. Proportional markups no profit dissipation have effect on the economy, policy that reduces nonproportional markup raises (lowers) welfare when it is higher (lower) than weighted average of other markups. With proportional...

Firms sometimes comply with externality-correcting policies by gaming the measure that determines policy. This harms buyers eroding information, but it benefits them when cost savings are passed through into prices. We develop a model highlights this tension and use to analyze of automobile carbon emission ratings in EU. document startling increases using novel data. then effects calibrated sim...

Mucin 1 (MUC1) is a diagnostic factor and therapy target in lung adenocarcinoma. MUC1 C-terminal intracellular domain (CD) interacts with estrogen receptor (ER) a and increases gene transcription in breast cancer cells. Because lung adenocarcinoma cells express functional ERa and ERb, we examined MUC1 expression and MUC1–ER interaction. Because blocking MUC1 CD with an inhibitory peptide (PMIP)...
