Issue Voting and Partisan Defections in Congressional Elections

In every election cycle the fate of some candidates is determined by partisans who defect from their usual voting habits to cast a ballot for the candidate of the opposing party. Defections in congressional elections have been attributed to incumbency, presidential approval, partisan strength, and factors related to individual voters. Our systematic assessment of the impact of issues on voter defections shows that party‐owned issues and performance issues associated favorably with one party affect the likelihood of partisan defections. The results suggest that congressional candidates can use issues to draw supporters away from the opposing party and to keep partisan voters loyal.     

PARTICIPATION AND FREQUENCY DURING CRIMINAL CAREERS ACROSS THE LIFE SPAN*

Recent advances and debates surrounding general and developmental as well as static and dynamic theories of crime can be traced to the 1986 National Academy of Science's Report on criminal careers and the discussion it generated. A key point of contention has been regarding the interpretation of the age–crime curve. According to Gottfredson and Hirschi (1986), the decline in the age–crime curve in early adulthood reflects decreasing individual offending frequency (λ) after the peak. Blumstein et al. (1986) claimed that the decline in the aggregate age–crime curve also could be attributable to the termination of criminal careers, and the average value of l could stay constant (or increase with age) for those offenders who remain active after that peak. Using data from the Criminal Career and Life Course Study—including information on criminal convictions across 60 years of almost 5,000 persons convicted in the Netherlands—and applying a two-part growth model that explicitly distinguishes between participation and frequency, the study outlined in this article assessed the participation–frequency debate. Results suggest that the decline in the age–crime curve in early adulthood reflects both decreasing individual offending participation and frequency after the peak, that the probabilities of participation and frequency are significantly related at the individual level, and that sex and marriage influence both participation and frequency.     

The portfolio allocation paradox: An investigation into the nature of a very strong but puzzling relationship

Abstract.  Perhaps the strongest empirical finding in political science is 'Gamson's Law': the near-perfect relationship that exists in parliamentary systems between a coalition party's seat contribution to the government and its quantitative allocation of cabinet portfolios. Nevertheless, doubts remain. What would happen if the salience or importance of the various portfolios was also taken into account? Should it not be the case that payoffs correspond with bargaining power rather than seat contributions? And perhaps most significantly, would addressing these issues produce evidence that the parties designated to form governments extract disproportionately large payoffs for themselves, as predicted by 'proposer' models of bargaining? Utilizing the results of a new expert survey of portfolio salience in 14 Western European countries, the authors of this article explore each of these questions. Their basic finding is that salience-weighted portfolios payoffs overwhelmingly mirror seat contributions, contra proposer models and any other models based on bargaining power. The article concludes with a discussion of the implications for formal models of bargaining.
