Litigation and the Political Clout of the Tobacco Companies: Cigarette Taxes, Prices, and the Master Settlement Agreement

The goal of our empirical analysis is to assess whether the changes in cigarette excise taxes and cigarette prices can be attributed to litigation brought by the states and the resulting settlements, holding other factors constant. Using pre-post as well as state excise taxes on beer as controls, the evidence provides support for the view that litigation changes the political equilibrium: state cigarette excise taxes were approximately $0.10 higher in the post-MSA period. For tobacco prices, the increases are attributable to the method the settlement used to structure payments as well as the market structure of the cigarette industry.Master Settlement Agreement, excise tax, tobacco

The Enigmatic HH 255

To gain insight into the nature of the peculiar Herbig-Haro object HH 255 (also called Burnham's nebula), we use previously published observations to derive information about the emission line fluxes as a function of position within HH 255 and compare them with the well-studied, and relatively well-behaved bow shock HH 1. There are some qualitative similarities in the H$\alpha$ and [O III] 5007 lines in both objects. However, in contrast to the expectation of the standard bow shock model, the fluxes of the [O I] 6300, [S II] 6731, and [N II] 6583 lines are essentially constant along the axis of the flow, while the electron density decreases, over a large distance within HH 255. We also explore the possibility that HH 255 represents the emission behind a standing or quasi-stationary shock. The shock faces upwind, and we suggest, using theoretical arguments, that it may be associated with the collimation of the southern outflow from T Tauri. Using a simplified magnetohydrodynamic simulation to illustrate the basic concept, we demonstrate that the existence of such a shock at the north edge of HH 255 could indeed explain its unusual kinematic and ionization properties. Whether or not such a shock can explain the detailed emission line stratification remains an open question.Comment: Accepted by PASP, 12 pages including 8 figure
