Financial ties between drug companies and medical researchers are thought to bias studies published in medical journals. To enable readers to account for such bias, most medical journals require authors to disclose potential conflicts of interest. We examine whether disclosure reduces article...

New generative artificial intelligence (AI) models, including large language models and image generators, have created new challenges for copyright policy as such models may be trained on data that includes copy-protected content. This paper examines this issue from an economics perspective and...

Financial reports present assets, liabilities, and earnings on a nominal basis (unadjusted for inflation). Using a novel dataset of nearly a century of financial reports, this paper examines whether and how inflation affects the relation between accounting earnings and stock market value, i.e.,...

We test and compare the effects of introduction of two new financial information technologies, EDGAR and XBRL, on well-known asset pricing anomalies often attributed to mispricing. EDGAR facilitates easier access to public accounting information about public firms; XBRL reduces the cost of...

The alcohol industry argues that alcohol excise taxes do not reduce heavy drinking because of substitutions to lower-cost products and that these taxes disproportionately burden low-income drinkers. Alternatively, some economists have argued that increases in alcohol excise taxes reduce heavy...

The post-COVID price surge has reignited interest in inflation's impact on American households. Even if anticipated and with full market adjustments, inflation affects households through its interaction with the fiscal system, which is the focus of this paper. Inflation affects households...

Using data on U.S. state and federal taxes and transfers over a quarter century, we estimate a regression model that yields the marginal effect of any shift of market income share from one quintile to another on the entire post tax, post-transfer income distribution. We identify exogenous income...

In 2021, the U.S. Congress temporarily expanded the Earned Income Tax Credit for workers without a qualifying child (childless EITC), to help counteract the impact of the COVID-19 pandemic on lower-wage working adults. This expansion roughly tripled the maximum benefits for qualifying filers and...

An impulse response is the dynamic average effect of an intervention across horizons. We use the well-known Kitagawa-Blinder-Oaxaca decomposition to explore a response's heterogeneity over time and over states of the economy. This can be implemented with a simple extension to the usual local...

The U.S. Supreme Court decision in the landmark 2018 Wayfair case greatly improved state governments' ability to enforce collection of sales taxes on a destination basis. This has reduced state tax competition with an essentially-untaxed internet, but has brought traditional cross-border...
