Trusted Hands: The Role of Community-Based Organizations in Enrolling Children in Public Health Insurance Programs

Trusted Hand is a new approach to enrolling traditionally hard-to-reach children in public health insurance programs. While the most common locations for enrollment assistance are state and local social service agencies and health clinics, many states are increasing their network to include a variety of community-based organizations that typically have not been involved in public health insurance. This Issue Brief, prepared by researchers at the University of Colorado Denver, details the advantages, as well as the challenges of this promising new strategy

Closing the Gap: How Improving Information Flow Can Help Community-Based Organizations Keep Uninsured Kids From Falling Through the Cracks

Evaluates how community-based organizations used a tool for systematic, ongoing data exchange with the state to monitor children's enrollment and redetermination status in public health insurance. Explores its potential to boost outreach and enrollment

Semiclassical Accuracy in Phase Space for Regular and Chaotic Dynamics

A phase-space semiclassical approximation valid to $O(\hbar)$ at short times is used to compare semiclassical accuracy for long-time and stationary observables in chaotic, stable, and mixed systems. Given the same level of semiclassical accuracy for the short time behavior, the squared semiclassical error in the chaotic system grows linearly in time, in contrast with quadratic growth in the classically stable system. In the chaotic system, the relative squared error at the Heisenberg time scales linearly with $\hbar_{\rm eff}$, allowing for unambiguous semiclassical determination of the eigenvalues and wave functions in the high-energy limit, while in the stable case the eigenvalue error always remains of the order of a mean level spacing. For a mixed classical phase space, eigenvalues associated with the chaotic sea can be semiclassically computed with greater accuracy than the ones associated with stable islands.Comment: 9 pages, 6 figures; to appear in Physical Review

Rupture cascades in a discrete element model of a porous sedimentary rock

We investigate the scaling properties of the sources of crackling noise in a fully-dynamic numerical model of sedimentary rocks subject to uniaxial compression. The model is initiated by filling a cylindrical container with randomly-sized spherical particles which are then connected by breakable beams. Loading at a constant strain rate the cohesive elements fail and the resulting stress transfer produces sudden bursts of correlated failures, directly analogous to the sources of acoustic emissions in real experiments. The source size, energy, and duration can all be quantified for an individual event, and the population analyzed for their scaling properties, including the distribution of waiting times between consecutive events. Despite the non-stationary loading, the results are all characterized by power law distributions over a broad range of scales in agreement with experiments. As failure is approached temporal correlation of events emerge accompanied by spatial clustering.Comment: 5 pages, 4 figure

Simple Pigovian Taxes vs. Emission Fees to Control Negative Externalities: A Pedagogical Note

Many economics texts introduce their analysis of negative externalities by examining a tax on the output of polluting firms, sometimes called a simple Pigovian tax, often pointing out that taxing pollution directly is superior to taxing output and proceeding to discuss an emission tee as an alternative. They do not show how and why an emission fee is more efficient than an output tax. This note presents a numerical example allowing comparison of the welfare effects of the two approaches, as well as showing why simply reducing the pollution intensity of polluters\u27 output would be inferior to an emission fee

The Treatment of Economic Issues in High School Government, Sociology, U.S. History and World History Texts

It is often argued that the declining support of free institutions which we have observed in our recent history is, in part, a result of economic illiteracy. That is, ignorance and misinformation about the workings of a voluntary exchange system and about the deleterious effects of governmental interference in that system lead to support of increased government intervention in the economy..

Subsidizing Non-Polluting Goods vs. Taxing Polluting Goods for Pollution Reduction

Pigovian taxes on polluters are politically unpopular, but subsidies for non-polluting sources are politically attractive. This paper presents a linear demand and supply model and numerical example to explore the trade-offs between taxing polluting sources of a good versus subsidizing non-polluting sources of the same good. While the model (along with the associated numerical example) shows the optimality of Pigovian taxes, it also shows how much welfare is reduced if subsidies for nonpolluters are employed instead. Further, it shows the optimal tax, given any level of subsidy and the optimal subsidy, given any level of tax

How Do Environmental and Natural Resource Economics Texts Deal with the Simple Model of the Intertemporal Allocation of a Nonrenewable Resource

Textbooks in Environmental and Natural Resource Economics invariably deal with the problem of allocating a non-renewable resource over time. The simplest version of that problem is the case of a resource that is to be allocated over two periods. The resource has a constant Marginal Extraction Cost (MEC). Most textbooks treat this case before moving on to more complex and realistic cases. This paper suggests the results that should be emphasized and the method that should be used to arrive at those results. It also points out the possible confusions that should be avoided. Finally, it examines how several well-known textbooks treat this issue
