The Lautenberg Act: Chemical Safety Overhaul of the Toxic Substances Control Act

On June 22, 2016, President Obama signed the Frank Lautenberg Chemical Safety for the 21st Century Act (Lautenberg Act), a landmark bipartisan compromise legislation designed to overhaul the Toxic Substances Control Act (TSCA). The Lautenberg Act makes it easier for the U.S. Environmental Protection Agency (EPA) to regulate toxic substances while providing the chemical industry with regulatory clarity and certainty. Law Librarians, practicing lawyers, and academics have taken note of this groundbreaking law that most likely will set the template for the next generation of environmental reform by tackling issues such as preemption of state law, protection of vulnerable populations, and the balance between industry’s need to protect confidential business information and the EPA’s need to access this information to evaluate chemicals

Continuous Differentiability of Renormalized Intersection Local Times in R^{1}

We study $\gamma_{k}(x_2,...,x_k;t)$, the k-fold renormalized self-intersection local time for Brownian motion in $R^1$. Our main result says that $\gamma_{k}(x_2,...,x_k;t)$ is continuously differentiable in the spatial variables, with probability 1

Scientists & Librarians Turn to “End of Presidential Term” Web Archive to Safeguard Climate Change Data

In anticipation of president-elect Donald Trump’s taking office, scientists have been working round the clock to safeguard federal government climate change data. Many academics and librarians share the concern that federal .gov climate data and information, for example from the EPA and NOAA websites, will be lost or become unavailable with the transition to the new administration. Fact is, a large percentage of information on federal government servers, including digital federal records, reports, and research, is not protected by any law or agency mandate, and can vanish within days of the arrival of a new president

Method to predict external store carriage loads at transonic speeds

A computational method for prediction of external store carriage loads at transonic speeds is described. The geometric flexibility required for treatment of isolated and underwing, pylon mounted stores is achieved by computing solutions on a five level embedded grid arrangement. A completely automated grid generation procedure facilitates applications. Store modeling capability consists of bodies of revolution with multiple fore and aft fins. A body conforming grid improves the accuracy of the computed store body flow field. A nonlinear finite difference relaxation scheme, developed specifically for modified transonic small disturbance flow equations, enhances numerical stability and accuracy. As a result, more accurate treatment of low aspect ratio, highly swept and tapered wing planforms is possible. A limited supersonic freestream capability is also provided. Pressure, load distribution, force and moment correlation show good agreement for several test cases

Public Finance: Essay for the Encyclopedia of Public Choice

Public Finance is the branch of economics that studies the taxing and spending activities of government. The term is something of a misnomer, because the fundamental issues are not financial (that is, relating to money). Rather, the key problems relate to the use of real resources. For this reason, some practitioners prefer the label public sector economics or simply public economics. Public finance encompasses both positive and normative analysis. Positive analysis deals with issues of cause and effect, for example, “If the government cuts the tax rate on gasoline, what will be the effect on gasoline consumption?” Normative analysis deals with ethical issues, for example, “Is it fairer to tax income or consumption?” Modern public finance focuses on the microeconomic functions of government, how the government does and should affect the allocation of resources and the distribution of income. For the most part, the macroeconomic functions of government--the use of taxing, spending, and monetary policies to affect the overall level of unemployment and the price level--are covered in other fields.

Housing Behavior and the Experimental Housing Allowance Program: What Have We Learned?

The purpose of this paper is to evaluate the Experimental Housing Allowance Program (EHAP). My focus is on what the experimental data have taught us that could not have been learned from more traditional sources of information. I review the major problems that confronted investigators using non-experimental data, and for each problem discuss whether or not it was mitigated by the availability of EHAP data .I conclude that if the goal was to obtain improved estimates of the behavioral response to housing allowances, a social experiment was not necessary.

The Marriage Tax is Down But Not Out

The public debate surrounding the Tax Reform Act of 1986 has paid little attention to the tax consequences of being married. Specifically, there has been virtually no discussion of the possible existence of an implicit "marriage tax"--the increase in the joint income tax liability of a man and woman when they marry. This lack of concern appears to be due to the perception that the new law has lowered marginal tax rates to such an extent that the magnitudes of marriage taxes (and subsidies) are inconsequential. In this paper, I show that to the contrary, the new law created large taxes on being married for some couples, and large subsidies for others. On the basis of a tax simulation model, I estimate that in 1988, 40 percent of all couples will pay an annual average marriage tax of about $1100, and 53 percent will receive an average subsidy of about$600. One striking result that emerges from the analysis is the relatively large marriage tax that will be borne by some low income couples with children. For such couples, the marriage tax can amount to 10 percent of joint gross income. Hence, the new tax law appears to quite "anti-family" for some low income workers.
