Admissible and sincere strategies under approval voting

This essay reasses the assumptions of the Brams-Fishburn theory of approval voting, and proposes modifications to make the theory correspond better with likely voting choices. With a small number of candidates, voters who use the inadmissible strategy of voting for all candidates can help to produce a result that better reflects the voters' wishes than is possible with admissible strategies, so we propose a widening of the definition of admissibility to encompass this case. With more than three candidates, we define first-order admissible strategies, which are the most likely strategies to be used in practice, and are also strongly sincere, in that a vote for any candidate is always accompanied by votes for all more or equally-preferred candidates. Their number is less under approval voting than under plurality voting. Both proposed modifications strengthen the technical arguments favoring approval voting over plurality voting.     

Survey research and racially charged elections: The case of David Duke in Louisiana

Accuracy in measuring vote intention has become a particular problem in elections involving candidates who take conservative positions on racial issues and who emphasize these issues in their campaigns. Consistent understatement of support for such candidates in preelection polls would seem to indicate a reluctance on the part of some survey respondents to honestly express their vote intention, perhaps due to the fear that their intended action might be interpreted as an expression of racism. This research, which utilizes surveys conducted during the 1991 Louisiana governor's election in which David Duke was prominently featured, attempts to develop more accurate alternative measures of support for racially conservative candidates. The findings indicate that more accurate and valid vote intention measures can be constructed through the use of candidate image variables. The findings also call into question the practice of attempting to develop more accurate measures of vote intention through simple reallocation of undecided voters based solely on race.     

Sincere and strategic voters: An Israeli study

The theoretical literature on voting behavior has shown that a rational voter may sometimes decide to vote for a candidate or party that does not constitute his or her first preference. Such voters are traditionally called strategic voters, in contrast to voters who act sincerely, i.e., those who always vote for their first preference regardless of how others are likely to vote. After discussing some of the problems associated with the definition of these two types of voters and suggesting a new operational definition, some attitudes and characteristics of these two types of voters are investigated. It was found that strategic voters constitute a very small percentage of the entire electorate, that their education level is significantly higher than that of sincere voters, that they tend more often to believe that polls influence voters' decisions and hence tend to delay their own final voting decision, that they tend more often than sincere voters to support small parties but do not tend more often than sincere voters to switch the party they decide to support from one election to the next, and that there is no significant difference between them and sincere voters regarding which governing coalition should/will form following an election.     

Comparing absentee and precinct voters: Voting on direct legislation

This paper addresses issues related to how absentee voters actually cast their ballots on propositions. If the liberalization of absentee laws changed either the composition or behavior of the electorate, then the outcome of the election may be affected. This paper tests whether the electoral behavior of absentee and precinct voters differs in regards to voting on propositions. The analysis is based on a sample of actual absentee and precinct voter ballots drawn from the approximately three million ballots cast in Los Angeles county for the 1992 general election. The analysis uses a nested model of voter participation and is estimated using the weighted exogenous sampling maximum likelihood method. We find that precinct and absentee voters do differ on both the propositions on which they cast votes and in their propensity to vote Yes for a proposition. For example, absentees appear to vote on fewer bonds and initiatives than do precinct voters. They also vote on fewer propositions dealing with state taxes, food taxes, and property taxes. In addition, given that a voter casts a valid vote, the propensity for absentee voters to vote Yes is higher on initiatives and propositions related to education, welfare, and health care than it is for precinct voters.     

A Competing Risks Model of Supreme Court Vacancies, 1789–1992

We hypothesize that Supreme Court justices will consider the likely ideological disposition of their successor in their decision to retire or remain on the Court. Furthermore, because a justice's decision to remain on the Court places him or her at risk of dying in office, it is necessary to consider a model of both voluntary and involuntary vacancies. Our study examines three broad classes of factors influential to Supreme Court vacancies: personal considerations, institutional context, and political influences. We assess the factors that affect the probability of a vacancy on the U.S. Supreme Court due to mortality and retirement at the individual level from 1789 to 1992, using a competing risk duration model and incorporating time-varying covariates. We find significant differences in the hazards of vacancy due to these two causes, and a number of factors are shown to influence the probability of a vacancy, including a general propensity to retire near the beginning of presidents' second terms. However, we find little evidence of the influence of political factors in either retirement-or death-related vacancies, suggesting that justices who retire do not generally do so for expressly political reasons and those who die in office rarely do so as a result of holding out for a like-minded replacement.     

Spin (and Pitch) Doctors: Campaign Strategies in Televised Political Debates

Political campaigns frequently set low expectations (using a low pitch) in televised political debates to make the later claim that their candidates have done better than expected. The limited credibility of campaign aides, coupled with the fact that perception often confirms expectations, makes this strategy psychologically problematic. In Study 1, when no post-debate information was provided, lowering expectations for a candidate led to lower ratings of performance. In Study 2, when positive feedback (a post-debate spin) was provided after a low pitch, participants did rate performance positively, but only when the spin was supplied by a credible media source. The same strategy when used by campaign strategists adversely impacted candidates, leading to lower ratings of debate performance and network coverage.     

Political deadlocks and distributional information: The value of the veil

Contractarian normative theory relies on the veil of ignorance construct to generate the political consensus required for its theories of justice. By eliminating distributional information, the veil is presumed to facilite consensus building by reducing conflict over the distributional effects of proposed constitutional rules or institutions. This paper explores the extent to which excessive distributional information might also impede the ordinary day-to-day decision making of democratic institutions. Our analysis suggests that distributive information makes political deadlocks under majority rule more likely. Statistical evidence suggests that the efficacy of the U.S. Congress has been reduced by the dramatic increase in distributional information made available to it over the past twenty five years.The authors would like to thank an anonymous referee and the participants of the Center for Study of Public Choice Luncheon Work Shop for helpful comments and suggestions.

The voter as juror: Attributing responsibility for economic conditions

One assumption of Key's reward-punishment theory that has attracted comparatively little attention is that voters hold the incumbent party responsible for all manner of economic fluctuations. A brief review of the survey literature in economic voting indicates that this assumption is in need of revision. The handful of existing studies in political science on responsibility attribution suffers from a lack of conceptual clarity and a failure to develop a theory of the attribution process. This paper outlines a model of economic voting in which people act as intuitive jurors using various decision rules to evaluate the evidence surrounding the president's responsibility for national economic problems. The generalizability of the framework and directions for future research are discussed     

Do the polls affect elections? Some 1980 evidence

This paper finds that the relatively favorable standing of Ronald Reagan in the preelection polls helped to generate a bandwagon effect in the 1980 presidential election. The models tested here suggest that this effect was most pronounced among voters who had the weakest prior political opinions and hence were most susceptible to suggestion through the media. While the bandwagon effect that is generated is modest, after controlling for an array of other political biases, it is substantial enough to warrant further attention as the dissemination of poll results becomes an increasingly attractive news event.     

Impersonal influence: Effects of representations of public opinion on political attitudes

Many phenomena of interest to political scientists involve what may be termed impersonal influence; that is, influence that derives from individuals' perceptions of others' attitudes, beliefs, or experiences. Others in this case refers not to the close friends and acquaintances that concerned the authors of classics such asThe People's Choice andPersonal Influence, but rather to the anonymous others outside an individual's realm of personal contacts. Modern mass media facilitate the influence of anonymous others by devoting considerable time and attention to portraying trends in mass opinion. This study explores the rationale for theories of impersonal influence, synthesizing existing research findings falling under this general theoretical framework, and investigating its psychological underpinnings using experiments embedded in representative surveys.     

The possibility of a desirable minimal state

There is a near consensus that organized special interests use influence to expand government into activities that are detrimental to the public at large. Consequently, as Lee (1989) suggests, it would be desirable if the general public had more control over political decisions — if government were more responsive to the public interest. However, the public interest like rent-seeking, is a subjective concept (Pasour, 1987).The possible existence of a desirable minimal state is not disproved by an approach that assumes utilities are interpersonally comparable. Individual utilities are subjective and ordinal and hence, cannot be added or weighted to determine the level of government that is socially optimal. If one accepts the subjectivist approach, it follows that no one can decide upon any policy whatever in the absence of an ultimate ethical or value judgment (Rothbard, 1982: 212). In this respect, determining the desirable minimal state is no different from determining whether an individual government program is desirable (or whether it represents rent-seeking waste).     

Optimal team and individual decision rules in uncertain dichotomous situations

In this paper, we consider the problem of determining the optimalteam decision rules in uncertain, binary (dichotomous) choice situations. We show that the Relative (Receiver) Operating Characteristic (ROC) curve plays a pivotal role in characterizing these rules. Specifically, the problem of finding the optimal aggregation rule involves finding a set ofcoupled operating points on the individual ROCs. Introducing the concept of a team ROC curve, we extend the method of characterizing decision capabilities of an individual decisionmaker (DM) to a team of DMs. Given the operating points of the individual DMs on their ROC curves, we show that the best aggregation rule is a likelihood ratio test. When the individual opinions are conditionally independent, the aggregation rule is a weighted majority rule, but with different asymmetric weights for the yes and no decisions. We show that the widely studied weighted majority rule with symmetric weights is a special case of the asymmetric weighted majority rule, wherein the competence level of each DM corresponds to the intersection of the main diagonal and the DM's ROC curve. Finally, we demonstrate that the performance of the team can be improved by jointly optimizing the aggregation rule and the individual decision rules, the latter possibly requiring a shift from the isolated (non-team) optimal operating point of each DM.Research supported by NSF grant #IRI-8902755 and ONR contract #N0014-90-J-1753.     

Candidate choice before the convention: The democrats in 1984

This paper analyzes prenomination presidential candidate preferences, using data from the Center for Political Studies' 1984 Continuous Monitoring Survey. Among Democratic identifiers, affective evaluations of the candidates were the strongest influence on candidate preference, but judgments concerning the candidates' nomination prospects and electability also influenced candidate preference, as did strength of party identification. The outcomes of particular primaries strongly influenced voters' opinions regarding the candidates' nomination prospects and, indirectly, their electability. Walter Mondale's decisive victory in the New York primary on April 3 apparently led to a bandwagon effect among Democratic voters across the nation; that is, the perception that Mondale was very likely to win the nomination produced a dramatic shift in candidate preference toward Mondale and away from Gary Hart.     

The median and the competitive equilibrium in one dimension

Two alternative models of legislative outcomes are the minimum winning coalition and the competitive equilibrium (Koford, 1982). In a unidimensional setting, the outcome under the former is the median, while the outcome under the latter is the highest net demand location.This paper describes the competitive equilibrium in a unidimensional model, and shows that under some common conditions it coincides with the median, in particular for pure redistributive issues. However, for distributive issues, the two equilibria will differ. Finally, the comparative statics of the two models are examined; while the winning coalition is sensitive only to changes in the location of the median, for distributive issues the competitive equilibrium has the standard economic comparative statics that the outcome adjusts in the direction of the change in preferences.     

A constitutional view of legislative pay

The distinction between constitutional rules and post-constitutional laws is often a fine line. However, this analysis suggests that, in the case of state legislative pay, constitutional rules are much more binding than post-constitutional restrictions. Further research in the area of constitutions from an economic point of view may yield fruitful results. As Tullock (1988: 140) has stated, The real importance of such an evaluation could be as a first step toward developing improved constitutional rules. Evaluating other areas of policy from a constitutional point of view might shed light on the path towards the development of optimal rules in a democratic process.Thanks go to Randy Holcombe for helpful comments and suggestions.     

Collective decision making and the limits on the organization's size

This essay clarifies the relationship between the technology of organizational decision making and the limits on the size of the group of decision makers within the organization. Viewing the number and quality of decision makers, and the time required for decision making as inputs in the production of collective decisions, we show that there exist generic organizational forces that offset the incentive to unlimited expansion of the organization. Even in a long run competitive environment with perfect markets for managers, unlimited duplication of the firm may not be economically feasible. We first analyze in a general setting and then illustrate in two stylized examples, the interplay between individual decisional quality, time required for an individual decision, direct and indirect costs of decision making, and the optimal number of decision makers (for example, management size).We are indebted to an anonymous referee of this journal and to P. Aranson for their very helpful comments and suggestions.     

Incentives and political contributions

Two implications from this research are noted. First, from a researcher's viewpoint, our research suggests the importance of age, wealth, tax rates, and marital status as determinants of political contributions by top U.S. wealth-holders. Therefore, these factors should be included in aggregated models that attempt to analyze the relations between such variables as voting, campaign expenditures and the outcomes of elections. Second, from politicians' viewpoints, this research suggests that individual economic variables such as marginal tax rates and wealth are major determinants of individual decisions to contribute to politicians. Assuming that such contributions reflect votes, this research suggests the relative importance of focusing campaign promises on economic variables — a strategy that low tax politicians like Ronald Reagan and George Bush may keenly be aware of.The views presented are those of the authors and do not necessarily represent those of the Treasury Department.     

Some properties of Hare voting with strategic voters

From the perspective of some common criteria for evaluating voting procedures, the results we offer in this essay will almost certainly be interpreted as inditments of STV. Even if we restrict preferences with conditions R1 and R2, STV is not necessarily incentive compatible. Moreover, strategic voting does not ensure the selection of Condorcet winning candidates or of Condorcet outcomes. This fact, moreover is not dependent on the existence of bogus equilibria — outcomes that exclude Condorcet candidates cannot be avoided under all circumstances even if we limit our analysis to strong or to individually stable equilibria.It is not the case, though, that the Condorcet criterion is the unique or even the most important criterion with which to evaluate election procedures. For example, we have not examined the extent to which STV ensures proportionality and we have not compared STV to other procedures. Despite the apparent deficiencies described in this essay, STV may yet prove to be a viable alternative to systems that seek to ensure proportionality by other means.     

Circumventing formal structure through commitment: Presidential influence and agenda control

Although the formal institutional structure that defines the temporal order of play in a policy game between the Congress and President ought to provide Congress with agenda power, the President is traditionally treated as the dominant player in this relationship. We show that if the President can make clear-cut commitments, presidential commitment can counter the dominance hierarchy and the complexion of equilibrium outcomes. Thus, the details of political interactions (in particular, the possibilities for commitment) may be as important as the formal specification of institutional structure.We thank Peter Aranson, David Austen-Smith, Ed Campos, Gerry Faulhaber, Art Frank, Ken Koford, William Riker, Janet Pack, the anonymous referees, and seminar participants at the University of Delaware, the University of Pennsylvania, and the University of Rochester for helpful comments, subject to the usual caveat.
