Why are Latinos More Politically Trusting than Other Americans?

This paper examines why Latinos, over the past thirty years, are consistently more trusting of the federal government than are Anglos and Blacks. We address this puzzle by turning to previous research on racial politics and political trust. Consistent with previous research, discrimination and generational status are important predictors of Latinos' levels of political trust, with first generation Latinos more trusting than later generation Latinos. Encounters with racial discrimination also make Latinos and Blacks less trusting of government. In contrast, Anglos' levels of political trust can be explained by their economic evaluations as well as their partisanship. While these findings are insightful, they do not directly address why inter-group differences arise when it comes to their trust in government. We argue that, combined with generational distinctions amongst Latinos in their levels of trust, the heavy flow of Latino immigration in the past thirty years has changed the Latino population in such a way that the views of the foreign-born are disproportionately represented in survey questions related to trust in government. This is producing a Latino population that is more inclined to trust government than Anglos or Blacks. We then examine the impact of political trust on individuals' opinions towards redistributive policies. Political trust has a strong and positive effect on Latinos' attitudes towards such policies. These findings have important implications for the future of public opinion and redistributive policy-making in the U.S

Party System Compactness: Measurement and Consequences

An important property of any party system is the set of choices it presents to the electorate. In this paper we analyze the distribution of parties relative to voters in the multidimensional issue space and introduce two measures of the dispersion of the parties in the issue space relative to the voters, which we call measures of the compactness of the parties in the issue space. We show how compactness is easily computed using standard survey items found on national election surveys. Because we study the spacing of the parties relative to the distribution of the voters, we produce metric-free measures of compactness of the party system. The measures can be used to compare party systems across issues, over time within countries, and across countries. Comparing the compactness of party systems across countries allows us to determine the relative amount of issue choice afforded voters in different polities. We examine the compactness of the issue space and test the impact it has on voter choice in four countries: the United States, the Netherlands, Canada, and Great Britain. We demonstrate that the more compact the distribution of the parties in the issue space on any given issue, the less voters weight that issue in their vote decision. Thus we provide evidence supporting theories suggesting that the greater the choice offered by the parties in an election, the more likely it is that issue voting will play a major role in that election

The Equivalence Principle and Anomalous Magnetic Moment Experiments

We investigate the possibility of testing of the Einstein Equivalence Principle (EEP) using measurements of anomalous magnetic moments of elementary particles. We compute the one loop correction for the $g-2$ anomaly within the class of non metric theories of gravity described by the \tmu formalism. We find several novel mechanisms for breaking the EEP whose origin is due purely to radiative corrections. We discuss the possibilities of setting new empirical constraints on these effects.Comment: 26 pages, latex, epsf, 1 figure, final version which appears in Physical Review

Optical and near-infrared spectrophotometric properties of Long Period Variables and other luminous red stars

Based on a new and large sample of optical and near-infrared spectra obtained at the Mount Stromlo and Siding Spring Observatories (Lancon & Wood 1998; Lancon & Wood, in preparation), spectrophotometric properties of cool oxygen- and carbon-rich Long Period Variables and supergiants are presented. Temperatures of oxygen-rich stars are assigned by comparison with synthetic spectra computed from up-to-date oxygen-rich model atmosphere grids. The existence of reliable optical and near-infrared temperature indicators is investigated. A narrow relation between the bolometric correction BC(I) and the broad-band colour I-J is obtained for oxygen-rich cool stars. The ability of specific near-infrared indices to separate luminosity classes, atmospheric chemistry or variability subtypes is discussed. Some comments are also given on extinction effects, water band strengths in Long Period Variables and the evaluation of 12CO/13CO ratio in red giants.Comment: 14 pages, 21 figures, Latex, accepted for publication in Astronomy and Astrophysics main journal.

Minimum Guaranteed Payments and Costly Cancellation Rights: A Stopping Game Perspective

We consider the valuation and optimal exercise policy of a δ- penalty minimum guaranteed payment option in the case where the value of the underlying dividend-paying asset follows a linear diffusion. We characterize both the value and optimal exercise policy of the considered game option explicitly and demonstrate that increased volatility increases the value of the option and postpones exercise by expanding the continuation region where exercising is suboptimal. An interesting and natural implication of this finding is that the value of the embedded cancellation rights of the issuer increase as volatility increases.minimum guaranteed payment, δ-penalty options, Dynkin games, linear diffusions
