Incentive compatibility solutions to social dilemmas change individual consequences of non-co-operative and co-operative acts such that self-maximizers will rationally choose to act in ways that promote the public good, i.e. to co-operate. The traditional selfish egoism assumption of rational choice requires dilemmas to be solved by either adding some likely punishment to defection or reward to co-operation. Dilemma co-operation can also, of course, be explained by relaxing the narrow self-interest assumption. By allowing for the possibility that outcomes of interdependent interactions are subjectively evaluated by reference to the actor's own as well as others' interests, or that people get additional utility (or avoid disutility) by following certain normative codes, co-operation in finitely repeated dilemmas can be rational.For examples of evidence of subjective transformations of given payoff matrices, see James Andreoni, ‘Giving with Impure Altrusim: Applications to Charity and Recardian Equivalence’, Journal of Political Economy, 97 (1989), 447–51; and Michael D. Kuhlman and Alfred F. J.

Nobody, least of all anyone intending to allude to sociology and stay respectable, should nowadays dare employ a generalization from a single instance. Nonetheless (since this is an introductory paragraph, and therefore only rhetoric), 1 I shall permit myself to do so and excuse the lapse by calling it an illustration. A professor of my acquaintance recently observed that reading an essay on Montesquieu (by one of my better students) had almost persuaded him to go himself and read Esprit des lois. In this country, I suspect, Montesquieu is less read than merely acknowledged as ‘a precursor of sociology’ or even as one of the ‘great theorists’ of sociology in general and political sociology in particular. One of the contributions that I hope this article will make is to persuade others, not merely historians of ideas, that Montesquieu should actually be read, because his ideas and his difficulties are important, interesting and instructive.

John Charvet, in a recent article, charges various ‘attempts to make of equality a substantive principle of society’ with being ‘incoherent and self contradictory’ (p. 13). The unifying theme of Charvet's article is that certain contenders for equality do so in a manner that logically presupposes the assuming away of those elements of social life which entitle us to talk about individuals as ‘human beings at all, i.e. as beings possessing the attributes of humanity’ (p. 2). I wish to show how little justified these charges are.

In the literature on new nations, much attention has been given to the threat to nationhood posed by cultural and linguistic variations, rather less to the political repercussions of the regional inequality with which such variations are often associated. Regional disparities in resources and services inherited at independence tend to be compounded by policies which stress growth rather than equity. Given that such imbalances are not easily or speedily corrected by means of compensatory economic policies – even if the will exists – the political vulnerability of governments to regional disaffection is bound up with the question of whether it is possible for a common national outlook to be superimposed upon regional variation. The purpose of this brief Note is to test two hypotheses which relate to this question against Kenyan data and experience.

The policy-oriented coalition models that were developed in the 1960s and 1970s generally required that the positions of political parties were measured at ordinal level. More recent models of coalition formation, however, have tended to assume that interval-level data on parties' policy positions are available. This need for interval-level data has raised serious practical problems for empirical research. Analysts frequently wish to examine patterns of coalition formation after several, or many, elections. Unfortunately, detailed interval-level data on parties' positions are generally available at only one or two points in time. While it can often be plausibly argued that parties will occupy fairly stable ordinal positions over time, it is extremely doubtful whether this is also the case for their interval positions.

This article provides an accessible introduction to the phenomenon of monotone likelihood in duration modeling of political events. Monotone likelihood arises when covariate values are monotonic when ordered according to failure time, causing parameter estimates to diverge toward infinity. Within political science duration model applications, this problem leads to misinterpretation, model misspecification and omitted variable biases, among other issues. Using a combination of mathematical exposition, Monte Carlo simulations and empirical applications, this article illustrates the advantages of Firth's penalized maximum-likelihood estimation in resolving the methodological complications underlying monotone likelihood. The results identify the conditions under which monotone likelihood is most acute and provide guidance for political scientists applying duration modeling techniques in their empirical research.

By the late 1960s the shift of the Labour party away from its traditional base among the urban working class appeared to be gaining momentum. The opinion polls showed a marked swing of working-class sentiment away from the party, and the policies advanced during the period, especially with regard to prices and incomes and industrial relations, hardly seemed designed to satisfy the redistributive concerns traditionally imputed to the working class. Indeed the government's overriding concern with the problem of the economy during a period in which the Labour party had a large majority over all other parties in the House of Commons was seen by one commentator as the final act of a tragic farce entitled ‘The Decline and Fall of Social Democracy’. Clearly this conclusion was drawn somewhat prematurely: in the 1970s there is fragmented evidence to suggest that the Labour party has regained the votes of a number of its traditional supporters who had previously defected, just as there is evidence that the ‘left’ of the party is asserting itself. However, the events of the early 1970s are not sufficient to refute the proposition that some kind of fundamental change either has occurred, or is occurring, in the relationship between the Labour party and its traditional supporters. Even if the curtain has yet to fall, there is no reason to believe that the play has not begun.

Electoral violence is perpetrated by anti-systemic actors opposed to the democratic system, as well as by those vying for power through the electoral process. Even though the motivations for violent tactics are distinct, we do not know whether intra- and anti-systemic violence differ in their effects. Focusing on state-level elections in India – a country that combines nationwide elections with persistent political violence – we demonstrate that the distinction is crucial for understanding spatial patterns of electoral violence and effects on election outcomes. Based on an original dataset of violence in legislative assembly elections between 1985 and 2008, we show that both tactics depress turnout overall but that the effect is larger for anti-systemic violence. Intra-systemic violence not only appears to be more selectively targeted, as it is more likely to occur in constituencies where the incumbent belongs to the state-level opposition, but also generates electoral benefits for the party in control of state government.

When authoritarian regimes liberalize, are there observable patterns in the ordering of reforms, and are these patterns distinct for cases that transition to democracy? While the prevailing literature tends to focus on exogenous ‘determinants’ of democracy, this letter describes the endogenous dynamics of liberalization itself. Using pairwise domination analysis, it assesses the institutional order of reforms during 371 episodes of liberalization in autocracies between 1900 and 2019. Based on twenty-four indicators of democratic institutions and practices, our findings reveal (1) a clear pattern of reform during liberalization episodes, (2) with strong similarities across outcomes, but also that (3) reforms to the administration of elections tend to develop comparatively earlier in episodes of liberalization that produce a democratic transition.

Do the styles politicians use influence how voters evaluate them, and does this matter more for women than for men? Politicians regularly use anecdotal arguments, emotional appeals and aggressive attacks when communicating with voters. However, that women politicians have been branded as ‘nasty’, ‘inhuman’ and ‘unfeminine’ suggests that these strategies may come at a price for some. I report on a novel survey experiment assessing whether voters are biased in their perceptions and evaluations of politicians' communication styles. By manipulating politician gender and argument style, I assess, first, whether politicians incur backlash when violating gender-based stereotypes and, secondly, whether differential perceptions of the styles themselves explain this backlash. I find that style usage has important consequences for how voters evaluate politicians but that this is not gendered. These results have important implications, as they suggest that women politicians may not need to conform to stereotype-expected behaviours in order to receive positive voter evaluations.

How do parties decide when to campaign on valence issues given high degrees of uncertainty? Although past studies have provided evidence of transnational emulation of parties' position-taking strategies, these findings do not directly apply to saliency strategies. Moreover, the exact diffusion mechanism remains largely elusive. Based on the issue saliency literature, this study develops novel theoretical propositions and argues that conscious learning enables parties to infer the relative utility of emphasizing consensual issues during an electoral campaign. The proposed theory gives rise to different expectations at the domestic and transnational levels because of the distinct logic of issue competition. By analyzing environmental issue emphasis in party manifestos, the authors find direct transnational dependencies and indirect spillover effects among the parties' saliency strategies. They identify conscious learning, rather than mere imitation or independent decision making, as the diffusion mechanism at work. Yet, in line with saliency-based theories, electoral competition mutes the diffusion of electoral strategies domestically.

Families are not only the first institution ever created, they are also, for most people, the first institution ever encountered. The preindustrial family structure, which was a function of local ecology and cooperation needs, instilled family members with different values, such as trust in strangers and respect for elders. These values passed through generations and, as we show in three studies, impact today's political attitudes and policies. First, using surveys of second-generation immigrants representing roughly 180 ethnicities living in 32 European countries, we show that the tighter kinship structure of a person's ancestors predicts right-wing cultural attitudes. Among those who are less engaged in politics, tighter ancestral kinship structure also predicts left-wing economic attitudes. In a second study, we control for country-level differences by comparing ethnic groups within countries and find that ancestral kinship strength predicts right-wing cultural attitudes but not left-wing economic attitudes. Finally, in a third study, we examine the policy implications of ancestral kinship. We show that stronger country-level ancestral kinship strength also increases anti-LGBT policies and welfare spending. Finally, we examine whether value systems link preindustrial kinship with modern political attitudes. In total, this work indicates that our political beliefs are rooted in the value systems and familial institutions created by our forebears.

We live in a world of text. Yet the sheer magnitude of social media data, coupled with a need to measure complex psychological constructs, has made this important source of data difficult to use. Researchers often engage in costly hand coding of thousands of texts using supervised techniques or rely on unsupervised techniques where the measurement of predefined constructs is difficult. We propose a novel approach that we call ‘super-unsupervised’ learning and demonstrate its usefulness by measuring the psychologically complex construct of online political hostility based on a large corpus of tweets. This approach accomplishes the feat by combining the best features of supervised and unsupervised learning techniques: measurements of complex psychological constructs without a single labelled data source. We first outline the approach before conducting a diverse series of tests that include: (i) face validity, (ii) convergent and discriminant validity, (iii) criterion validity, (iv) external validity, and (v) ecological validity.

Legislators are likely to substantively represent groups to which they belong or with which they have some particular affinity. However, there are electoral systems that diminish this tendency and systems that promote it. More precisely, as district magnitude increases, representatives will be freer to focus on issues that are not decisive of vote choice for most voters. In this letter, we use a case of electoral reform and the nature of the post-reform chamber (Chile's Chamber of Deputies) to test whether increasing district magnitude makes it more likely that women will focus on women's issues. A series of tests on multiple sets of observations show robust results for the conclusion that as the number of candidates elected in a district increases, elected women become more likely to pursue women's issues.

One of the most profound changes in the interest group sector over the last fifty years is interest groups’ increasing need to attract financial donors in order to assure long-term sustainability. Groups’ growing propensity to attract ‘chequebook’ members is thought to compromise their ability to foster the personal involvement of individuals in their communities. Yet we know very little about the consequences of these dynamics for the strength of the interest group sector in American communities. This widespread macro-level analysis of the interest group sector indicates that human capital is more important than financial capital for the strength of a community's interest group sector. Financially disadvantaged communities may still enjoy the benefits of a strong interest group sector provided they have a citizenry equipped with time to donate.

Paul Abramson's Note (this Journal, p. 505) is an interesting exercise in comparative data reanalysis. But we do not believe that it effectively refutes our argument that partisan weakening in Britain has been caused by ‘period’ rather than ‘generational’ factors.
