Each member of the group holds an opinion regarding the most suitable (best) alternative for which he or she votes. In this setting, the individual votes are based on their decisional competencies, which hinge on the information to which they are exposed and on their ability to make use of that information. The main question is how to translate the group members’ voting profile to a single collective choice. This chapter studies different aspects of this question in the context of binary voting where the group faces only two alternatives. The selection of an appropriate aggregation rule is a central issue in the fields of social choice, public choice, voting theory, and collective decision making. Since the votes are based on the individual competencies, the applied aggregation rule should take into account not only the voting profile but also the competency profile. In fact, it should also take into consideration any other relevant environmental information such as the asymmetry between the feasible alternatives, the dependence between individual votes, decision-making costs, and the available past record of the voters’ decisions. The chapter focuses on the clarification of the relationship between the performance of binary aggregation rules and the relevant variables and parameters. This has direct normative implications regarding the desirable mode of collective decision making and, in particular, regarding the desirable aggregation rule and the size and the composition of the decision-making body.","PeriodicalId":328044,"journal":{"name":"The Oxford Handbook of Public Choice, Volume 1","volume":"430 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132907272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sincere voter always casts a sincere vote, while the strategic voter casts a sincere or strategic vote depending on the context and the voting rule. This leads to two definitions of strategic voting: a broad one, where a strategic vote is one that is partly based on expectations about the outcome of the election, and a narrow one, where a strategic vote also entails not voting sincerely. The chapter then reviews three types of empirical research that differ with respect to the type of data used: the observation of electoral outcomes, survey data, and lab experiments. That literature has confirmed that indeed some voters cast a strategic vote, though many studies have found most votes to be sincere. That research has also shown that there is some degree of strategic voting under all kinds of voting rules; that, contrary to conventional wisdom, there is as much strategic voting under proportional representation as under plurality rule; and that the propensity to vote strategically depends very much on the type of information that is available.","PeriodicalId":328044,"journal":{"name":"The Oxford Handbook of Public Choice, Volume 1","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124787715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

What does it take to develop a formally precise and descriptively valid model of persuasion? Any such model should specify formally concise definitions of hypothetical constructs such as preferences or attitudes. The chapter reviews weak order and semiorder models of preferences that are grounded in decision theory. Such a model should also spell out how hypothetical constructs relate to observable behavior, such as feeling thermometer ratings. The chapter reviews response processes that, in some cases, accommodate within and across respondent heterogeneity in overt behavior. The model should furthermore specify formally what it means to change one’s preference over time and how that change relates to the persuasive environment. The chapter treats preference change as a continuous time stochastic process on a graph of preference states. The most innovative feature of the approach is to model the (perceived) persuasive environment itself also as a hypothetical construct that is not directly/objectively observable by the researcher. Last but not least, the chapter discusses how to accommodate partisan differences, how to incorporate respondents with immutable preferences, and the possibility that respondents may tune in and out of a persuasive campaign. The emphasis of the chapter lies in explaining key conceptual ideas grounded in decision theory and mathematical psychology.","PeriodicalId":328044,"journal":{"name":"The Oxford Handbook of Public Choice, Volume 1","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116347148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tension in such a game arises because the interests of sender and receiver are not fully aligned. Leaders often have incentives to mislead their followers. How leaders can communicate credibly to their followers has recently become a topic of study. This chapter surveys and synthesizes that literature. It offers an introduction to sender-receiver games and considers ways in which the problem of an untrustworthy leader may be overcome.

This chapter presents a framework and taxonomy for the study of corruption. Within this framework, corruption is conceptualized as a particular instance of the more general social phenomena we call influence-seeking activities.

Theory suggests that no process is immune. The study of manipulation provides principles and insights about how parts of complex decision systems work together and how changes in one part can have broad impact. Thus, manipulation strategies are derived from many features of voting processes. Public choice theory highlights relationships among group choice, rules, and individual decisions. The theory is a source of surprises and paradoxes that suggests tools for manipulation of group choices. This chapter catalogs many of the surprises that harbor potential sources of manipulation in the hope that a deeper understanding of manipulation will produce better systems.","PeriodicalId":328044,"journal":{"name":"The Oxford Handbook of Public Choice, Volume 1","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124893220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is much about politics that can be understood as the direct consequence of purposeful behavior, from public policies and electoral outcomes to institutional design and evolution. The second half of the chapter provides a short overview of the core results and puzzles explored by the public choice research program. These can roughly be divided into the theories of elections, interest group politics, and constitutional political economy. In addition, there are a variety of results from empirical tests of those theories and positive and normative methodological issues.

Rents are assigned through decisions about budgetary spending and taxation. Public policy creates and assigns rents through decisions about regulation of competition, international trade, the environment, foreign aid, and more. Contestable rents are also found outside of government, for example in academia, or when contests take place for mates. There is a social loss when resources and initiative used in contesting rents could have been used productively. Lack of data and denial by successful rent seekers that rent seeking took place are obstacles to direct measurement of social loss. Contest models are therefore used to infer magnitudes of social loss. The models show conditions under which the observable value of a rent can be used to approximate the generally unobservable value of resources used in contesting the rent. The generic contest model describes social losses when individuals seek a personal benefit. Social losses are diminished when, as is characteristic of democracies, groups contest collective benefits. Views on the importance of rent seeking can be influenced by ideology. Government as seeking to maximize social welfare is inconsistent with political creation of contestable rents that are assigned for privileged benefit.","PeriodicalId":328044,"journal":{"name":"The Oxford Handbook of Public Choice, Volume 1","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131189531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
