Party policy equilibrium for alternative spatial voting models: An application to the Norwegian storting

In recent years a lively debate has emerged concerning the empirical status of the traditional proximity spatial model versus a directional model of voter choice. The central reason for this scholarly interest concerns these models' contrasting implications for parties' policy positioning, with the directional model motivating parties to present extreme policies, but the proximity model promoting centrist positions. To this point, however, there exist no studies that compute parties' optimal strategies in historical elections, for these competing models. This article addresses this issue, by examining party policy strategies in a multiparty electorate for three different vote models: (a) the proximity model, (b) a directional model (c) a mixed model which combines proximity and directional components. Each model incorporates past voting history and the random effects of unmeasured variables. Using parameter estimates derived from analyses of survey data from the 1989 Norwegian Election Study we compute — for each of these vote models — the configuration of party policy positions that maximize each party's vote share in relation to those of the other parties. We find that for each model, such a vote–maximizing configuration exists, but — for the proximity model — represents an unrealistic, tightly clustered array. A mixed proximity–directional model, however, provides by far the most convincing account of parties' actual policy strategies with regard to dispersion and vote share.     

An economic analysis of the use of citations in the law

This paper examines the use of citations analysis as an empiricaltool for understanding aspects of the legal system and for improvingthe performance of the system. Emphasis is laid on the use ofsuch analysis as a means to evaluate courts and judges (andtherefore as a judicial-management tool), to test hypothesesabout judicial behavior, and to evaluate and improve legal scholarship.It is argued that economic models, particularly of reputationand of human capital, can frame and guide the use of citationsanalysis in law.     

Changes in the Location of the Median Voter in theU.S. House of Representatives, 1963–1996

We consider the degree of ideological polarizationwithin and between the parties in the U.S. House ofRepresentatives for the period 1963–1996, using theGroseclose, Levitt and Snyder (1996) adjustment method for ADA and ACU scores to ensure over timecomparability of roll call voting data. We focusespecially on the median House member, since webelieve that change in the median offers a bettermeasure of the impact of the change in party controlthan does changes in the mean roll-call votingscore. Our data analysis makes two general points. First andforemost, when we looked at the change in the locationof the House median voter, we found a dramatic changeafter the Republicans gained a majority in the House in1994. After the Republicans became a majority in theHouse, the ADA median in the House in 1995–1996 was at24, far closer to the Republican median of 4 than tothe Democratic median of 83. The shift in medianfrom 1993–1994 to 1994–1995 involved a change of over 25points in one election – far and away the greatestsingle shift in ideology of the modern era. Incontrast, the mean changed only 1 point overthis same period. Second, for the three decades weinvestigated, we found three historical epochs vis a visthe relative locations of the ADA (or ACU) floormedian and the ADA (or ACU) floor mean in the U.S.House of Representatives – two inflection points in1983 and 1994 which are related to trends in regionalrealignment.     

Assimilation and contrast effects in voter projections of party locations: Evidence from Norway, France, and the USA

In the standard Downsian model, voters are assumed to choose parties based on the extent of ideological proximity between the voter's own position and that of the party. Yet it is also well known that there are rationalization and projection effects such that voters tend to misestimate the policy platforms of candidates or parties to which they are sympathetic by overstating the correspondence between those positions and the voter's own preferences (see, e.g., Markus & Converse 1979; Granberg & Brent 1980; Granberg & Holmberg 1988; Merrill & Grofman 1999). Here we follow insights in the psychological literature on persuasion (Sherif & Hovland 1961; Parducci & Marshall 1962) by distinguishing between assimilation and contrast effects. Assimilation refers to shortening the perceived ideological distance between oneself and parties one favors; contrast refers to exaggerating the distance to parties for which one does not intend to vote. Using survey data on voter self–placements and party placements on ideological scales for the seven major Norwegian parties, five major French parties, and two major American parties we show that both assimilation and contrast effects are present in each country to a considerable degree.We also investigate the possible effects of randomness in party placement and scale interpretation – effects that can easily be confounded with assimilation but not so easily with contrast.

Why candidate divergence should be expected to be just as great (or even greater) in competitive seats as in non-competitive ones

Basic Downsian theory predicts candidate convergence toward the views of the median voter in two-candidate elections. Common journalistic wisdom, moreover, leads us to expect these centripetal pressures to be strongest when elections are expected to be close. Yet, the available evidence from the US Congress disconfirms this prediction. To explain this counterintuitive result, we develop a spatial model that allows us to understand the complex interactions of political competition, partisan loyalties, and incentives for voter turnout that can lead office-seeking candidates, especially candidates in close elections, to emphasize policy appeals to their voter base rather than courting the median voter.     

Assimilation and contrast effects in voter projections of party locations: Evidence from Norway,France, and the USA

Abstract. In the standard Downsian model, voters are assumed to choose parties based on the extent of ideological proximity between the voter's own position and that of the party. Yet it is also well known that there are rationalization and projection effects such that voters tend to misestimate the policy platforms of candidates or parties to which they are sympathetic by overstating the correspondence between those positions and the voter's own preferences (see, e.g., Markus & Converse 1979; Granberg & Brent 1980; Granberg & Holmberg 1988; Merrill & Grofman 1999). Here we follow insights in the psychological literature on persuasion (Sherif & Hovland 1961; Parducci & Marshall 1962) by distinguishing between assimilation and contrast effects. Assimilation refers to shortening the perceived ideological distance between oneself and parties one favors; contrast refers to exaggerating the distance to parties for which one does not intend to vote. Using survey data on voter self–placements and party placements on ideological scales for the seven major Norwegian parties, five major French parties, and two major American parties we show that both assimilation and contrast effects are present in each country to a considerable degree.We also investigate the possible effects of randomness in party placement and scale interpretation – effects that can easily be confounded with assimilation but not so easily with contrast.     

The evolution of the New Patriotic Party in Ghana

This paper examines the emergence and development of the ruling New Patriotic Party (NPP) government in the context of a broader examination of the roles of political parties within the Ghanaian political landscape. After describing the political architecture as well as some significant constitutional issues of Ghana's democracy and the roles played by other societal stakeholders, the paper examines the rationale for the formation of the NPP, its manifesto, structure, constituency, power brokers. It then analyses various aspects of the implementation (or not) of the NPP's political and economic objectives since it came to power in 2000 with a message of ‘positive change’. The electoral politics of the campaigns against its major opposition, the National Democratic Congress (NDC), and issues of regionalism, ethnicity and other factors are considered in detail. The paper concludes with some lessons learned and generic recommendations for emerging African political parties in relatively young democracies.
