© 2017 Elsevier Ltd Volatility is a widely used term in political science, but even the most widely used measure of volatility, Pedersen's index, can mask as much as it reveals. His simple and elegant calculation has become part of the political science toolbox, but scholars employing this tool have tended to produce distinctly different results thanks to a series of decisions about measurement and classification. Using examples from Central Europe the critical role of decisions related to party continuity and threshold of inclusion are identified. The article not only unpacks the underlying questions addressed by different uses of Pedersen's index, but offers standards for choosing particular methods over others and outlines steps that should be followed in creating a more accurate measure of volatility.

The study of electoral stability or volatility in Latin America calls attention to profound differences between most Latin American party systems, which are quite volatile, and West European party systems, which remain comparatively stable notwithstanding a trend toward greater volatility in recent decades. The examination of Latin American party systems poses interesting questions about why they differ so markedly from West European systems along this important dimension and what the consequences are for democracy. This paper focuses on volatility in one country, Brazil, in order to examine these issues. I make four arguments: that the Brazilian party system was moderately volatile during Brazil's first democracy (1946-64); that the party system has been highly volatile since 1982; that Brazil's volatility is much higher than that in the advanced industrial democracies; and finally, that the high volatility of the post-1985 period was caused by a combination of structural and institutional factors inimical to strong ties between citizens, political elites and parties, and further boosted by the dismal economic results of 1987-94.

Examines electoral volatility in Brazil, in a comparison of the Latin American & West European party systems. It is argued that (1) the Brazilian party system was moderately volatile during Brazil's first democracy (1946-1964); (2) the party system has been highly volatile since 1982; (3) Brazil's volatility is much higher than that in the advanced industrial democracies; & (4) the high volatility of the post-1985 period was caused by a combination of structural & institutional factors inimical to strong ties between citizens, political elites, & parties, & further boosted by the dismal economic results of 1987-1994. 7 Tables, 35 References.

AbstractThis article explores the quantitative and qualitative dimensions of volatility and their implications for cultural analysis in a range of fields. From quantitative finance, it takes the notion of 'delta-hedging', the suspension or neutralization of directionality to get access to volatility, and applies this to qualitative areas such as surfing, dance, cinema, and language.
