   Abstract = {This paper uses a finite mixture model to demonstrate that
             some police officers are more likely than others to stop
             black drivers. The conclusion is one that though widely
             believed has proven challenging to establish empirically. By
             doing so, the paper makes two contributions, one conceptual
             and one statistical. First, it more closely aligns with the
             understanding of racial profiling as signifying that black
             individuals experience more frequent interaction with the
             police. While disproportional susceptibility to vehicle
             searches also exemplifies profiling, being pulled over is a
             much more common margin for potential profiling, which this
             paper models a tractable way of identifying. Second, studies
             of secondary decisions such as searches frequently assume
             that there is no bias in the initial stop decision. An
             analysis of traffic stops across eight states questions this
             assumption, concluding that stopped drivers constitute a
             selected sample. Although bias is theoretically continuous,
             average behavior actually fits well into two distinct
             groups, with 30–40% of officers in the group that exhibits
             a relatively high propensity to stop black drivers. The
             implication is that race-based policing is more prevalent
             than the “rotten apples” theory might

   Abstract = {The COVID-19 pandemic has magnified U.S. health disparities.
             Though disparities in COVID-19 hospitalization by
             race-ethnicity are large, disparities by income and
             education have not been studied. Using an index based on
             preexisting health conditions and age, we estimate
             disparities in vulnerability to hospitalization from
             COVID-19 by income, education, and race-ethnicity for U.S.
             adults. The index uses estimates of health condition and age
             effects on hospitalization for respiratory distress prior to
             the pandemic validated on COVID-19 hospitalizations. We find
             vulnerability arising from preexisting conditions is nearly
             three times higher for bottom versus top income quartile
             adults and 60 % higher for those with a high-school degree
             relative to a college degree. Though non-Hispanic Blacks are
             more vulnerable than non-Hispanic Whites at comparable ages,
             among all adults the groups are equally vulnerable because
             non-Hispanic Blacks are younger. Hispanics are the least
             vulnerable. Results suggest that income and education
             disparities in hospitalization are likely large and should
             be examined directly to further understand the unequal
             impact of the pandemic.},

   Abstract = {In this article, we present a model of the electricity
             sector where generation technologies are intermittent. The
             economic value of an electricity generation technology is
             given by integrating its production profile with the market
             price of electricity. We use estimates of the consumer's
             intertemporal elasticity of substitution for electricity
             consumption while parameterizing the model empirically to
             numerically calculate the elasticity between renewables and
             fossil energy. We find that there is a non-constant
             elasticity of substitution between renewable and fossil
             energy that depends on prices and intermittency. This
             suggests that the efficacy and welfare effects of carbon
             taxes and renewable subsidies vary geographically.
             Subsidizing research into battery technology and tailoring
             policy for local energy markets can mitigate these
             distributional side effects while complementing traditional
             policies used to promote renewable energy.},

   Abstract = {The Haber-Bosch process produces ammonia from hydrogen and
             nitrogen gases in a globally important energy-intensive
             process that uses coal or natural gas as a fuel and hydrogen
             source. Direct electrochemical ammonia synthesis from
             nitrogen and water using renewable energy sources presents
             an alternative to the Haber-Bosch process that would be more
             sustainable. Additionally, the different production
             structure of direct electrochemical nitrogen reduction
             technology suggests a supply chain alternative to the
             ammonia industry and a method for load leveling of the
             electrical grid. This alternative route to ammonia from
             dinitrogen would require smaller capital investments than
             the Haber-Bosch process and would not require a fossil fuel
             supply. The impact of dynamic electrical power pricing is
             analyzed for a system that could take advantage of pricing
             volatility. We show that, under certain scenarios, at
             achievable levels of energy efficiency with a future
             electrocatalyst, direct nitrogen reduction would be
             economically competitive or advantageous compared with
             Haber-Bosch-based ammonia production.},

   Abstract = {This paper documents facts about the structure of business
             taxation in China using administrative tax data from 2007 to
             2011 from the State Taxation Administration.We first
             document the importance of different business taxes across
             industries. Although corporate income taxes play an
             important role for manufacturing firms, these firms also
             remit a large share of their tax payments through the
             value-added tax system, through the excise tax system, and
             through payroll taxes. Gross receipts taxes play an
             important role for firms in other industries, leading to
             spillovers that may affect the overall economy. Second, we
             evaluate whether the structure of China’s tax revenue
             matches its stage of development. A crosscountry comparison
             of sources of government revenue shows that China collects a
             high share of tax revenue fromtaxes on goods and services
             and a high share of income tax on corporations. Finally, we
             study whether firmlevel differences in effective tax rates
             can be an important source of allocative
             inefficiencies.Decomposing the variation in effective tax
             rates across firms, we find that government policies,
             including loss carry-forward provisions and preferential
             policies for regional, foreign, small, and high-tech firms,
             have significant explanatory power. Nonetheless, although
             effective tax rates vary along a number of dimensions, tax
             policy does not explain the large dispersion in the returns
             to factors of production across firms.},

   url = {},
   Abstract = {This paper studies how sellers behave when their consumers
             have difficulty in detecting small differences. These
             consumers pose a problem because, even if a good deal
             exists, they cannot appreciate it if it is barely better
             than their outside options. This creates a role for a second
             deal, either marketed by the same seller or by another
             seller, even when consumers are homogeneous in their tastes.
             If the same seller markets the second deal, it will
             strategically position the first as a good deal, and the
             second as a bad deal, and use the bad deal to help consumers
             appreciate the good deal. If another seller markets the
             second deal, the two sellers will become specialized as,
             respectively, good-deal and bad-deal providers. Both sellers
             free-ride each other. The good-deal provider is happy
             because the bad deal helps consumers appreciate its good
             deal; while the bad-deal provider hides behind the presence
             of the good deal and manages to make a sale some of the

   Journal = {Journal of Business & Economic Statistics},
   Year = {2020},
   Month = {January},
   url = {},
   Abstract = {We develop new high-frequency-based inference procedures for
             analyzing the relationship between jumps in instantaneous
             moments of stochastic processes. The estimation consists of
             two steps: the nonparametric determination of the jumps as
             differences in local averages, followed by a
             minimum-distance type estimation of the parameters of
             interest under general loss functions that include both
             least-square and more robust quantile regressions as special
             cases. The resulting asymptotic distribution of the
             estimator, derived under an infill asymptotic setting, is
             highly nonstandard and generally not mixed normal. In
             addition, we establish the validity of a novel bootstrap
             algorithm for making feasible inference including
             bias-correction. The new methods are applied in a study on
