摘要：A low carbon fuel standard (LCFS) seeks to reduce greenhouse gas emissions by limiting the carbon intensity of fuels. We show this decreases high carbon fuel production but increases low carbon fuel production, possibly increasing net carbon emissions. The LCFS cannot be efficient, and the best LCFS may be nonbinding. We simulate a national LCFS on gasoline and ethanol. For a broad parameter range, emissions decrease, energy prices increase, abatement costs are large ($80-$760 billion annually...

摘要：We examine the effects of presentation and information on the takeup of financial subsidies for retirement saving in a large randomized experiment carried out with H&R Block. The subsidies raise take-up and contributions with larger effects when the subsidy is characterized as a matching contribution rather than an equivalent-value tax credit (or cash back), and when filers are informed before the tax season about the subsidy. The results imply that both pure incentives and the presentation of...

摘要：Using data from the Continuing Survey of Food Intake by Individuals, this paper describes the shape of consumption profiles over the month for Social Security benefit recipients that have saved different amounts for retirement. Individuals with income mostly made up of Social Security and savings smooth consumption over the pay period, while individuals without savings consume 25 percent fewer calories the week before they receive checks relative to the week afterwards. The findings for indivi...
