Summary

This chapter investigates the electoral consequences of broken promises in the context of globalization. Combining large-n observational data with a survey experiment and a in-depth case study of French voters, it demonstrates that voters do punish governing parties for failing to fulfill campaign pledges, and this punishment intensifies in more globalized environments. Contrary to claims that globalization might provide excuses for unfulfilled promises, the findings suggest that globalization amplifies voters’ concerns about competence and follow-through. As ideological differences between parties shrink and governing space contracts, pledge fulfillment becomes a key signal of competence, heightening electoral costs for unkept promises.

Information

Figure 0

Figure 6.1 Unfulfilled promises and change in vote share

Note: The graph presents coefficients (round circles) with 95 percent confidence intervals (bars) from an ordinary least squares model with standard errors that are clustered by country. The dependent variable is the change in the absolute vote share of each incumbent political party from the previous election to the current election. All continuous explanatory variables are standardized to a mean of 0 and a standard deviation of 1. The dashed line represents a coefficient of 0, corresponding to no effect. Full numerical results in tabular form are presented in the online Supplementary Material. EMI, Economic Misery Index.

Figure 6.2 Predicted values for the effect of broken promises on change in vote share

Note: The graph presents the predicted change in vote shares, together with 95 percent confidence intervals, for different proportions of broken election promises. The graph is based on the regression model presented in Figure 6.1.
Figure 2

Figure 6.3 Marginal effect of broken promises on change in vote share for different levels of globalization

Note: The figure plots the marginal effect and 95 percent confidence intervals of the effect of the proportion of broken promises on changes in governing parties’ vote shares, conditional on the country’s integration into the global economy, where higher values indicate deeper integration. Globalization is standardized to a mean of 0 and a standard deviation of 1. The dashed line represents a coefficient of 0, corresponding to no effect. Full numerical results in tabular form are presented in the online Supplementary Material.

Figure 6.6 Main experimental results.Figure 6.6 long description.

Note: The figure presents the results of difference-between-means tests that compare average responses on Politician Likeability for a sample where the politician breaks his clear promise to a sample where the politician fulfills his clear promise. The top graph represents the experimental results for the sample that does not receive the globalization treatment. The bottom graph represents the experimental results for the sample that receives the globalization treatment. For each graph, the top row refers to the treatment where the politician keeps his clear promise; the bottom row refers to the treatment where the politician breaks his clear promise. The graph shows the means for each sample using a light gray square, including 95 percent confidence intervals (black bars), as well as a histogram with information on sample distribution at various values of the dependent variable along the x-axis, here Politician Likeability.

Figure 6.7 Globalization shock’s limited benefitFigure 6.7 long description.

Note: The figure presents the results of a difference-between-means test that compares average responses about Politician Likeability in a sample where the politician breaks his promise and respondents do not receive the globalization treatment to a sample where the politician breaks his promise, and the respondents receive the globalization treatment. The graph shows the means for each sample using a light gray square, including 95 percent confidence intervals (black bars), as well as a histogram with information on sample distribution at various values of the dependent variable along the x-axis, here Politician Likeability. The top row refers to the treatment where a globalization shock makes promise keeping more challenging; the bottom row refers to the treatment where no globalization shock occurs.

Figure 6.9 Respondents’ beliefs about promise keeping and retrospective sanctioningFigure 6.9 long description.

Note: The figure presents the results of a difference-between-means test that compares average responses on Politician Likeability for a sample where the politician breaks his promise and respondents believe that politicians should not break their promises to a sample where the politician breaks his promise and respondents believe that politicians can be right to break their promises if circumstances change. The graph shows the means for each sample using a light gray square, including 95 percent confidence intervals (black bars), as well as a histogram with information on sample distribution at various values of the dependent variable along the x-axis, here Politician Likeability.
