Dramatic increases in globalisation resulted in autocratic countries being exposed to the institutions and values of their democratic trade partners. Exploiting improvements in air transportation relative to sea shipping that occurred over the last five decades, and combining survey data with country level measures of democracy from 1960 to 2015, Tabellini and Magristretti document that trade with democracies increases both citizens’ support for democracy and countries’ democracy scores, and investigate the feasibility of the mechanisms through which this democratisation occurs.
Between 1960 and 2010, democracy and globalisation rose dramatically (see Figure 1). As a result, citizens of non-democratic countries might have been increasingly exposed to the institutions and the values of their more democratic partners. Does economic integration with democracies promote the transmission of democratic values and support the consolidation of democracy across countries? Exposure to democracy in their own country has been shown to improve both individuals’ attitudes towards democracy and the stability of countries’ institutions (Persson and Tabellini 2009, Acemoglu et al. 2021). Yet, less is known about the role that exposure to trade partners’ democracy can have on individuals’ support for democracy and on the quality of countries’ institutions.

Data and methodology
In our recent paper (Tabellini and Magistretti 2023), we seek to fill this gap by studying the effects of economic integration with democracies on individuals’ attitudes, and on countries’ institutions, from 1960 to 2015. We begin by exploiting within-country, cross-cohort variation in individuals’ exposure to democracy of a country’s trade partners during their impressionable years (ages 16-24), a period in an individual’s life when political and economic preferences are particularly malleable to economic shocks (Giuliano and Spilimbergo 2022, 2023). We rely on data from the Integrated Value Surveys, which include more than 220,000 respondents across 74 countries, to test whether individuals who grew up while their country was trading more with democratic partners are more supportive of democracy at the time of the survey. We compare individuals’ attitudes towards democracy in age cohorts that, during the impressionable years, were more (or less) exposed to trade with democratic partners, relative to other cohorts in the same country and to the same cohorts in other countries, over time.
Next, we turn to the country-level analysis, using an unbalanced sample of 116 countries between 1960 and 2015. We examine the effects of economic integration with democratic and non-democratic partners on countries’ democracy scores, measured by the Polity2 index from the Polity5 Project.
To address potential endogeneity issues (such as countries becoming more democratic first, and then opening up to trade), we rely on the trade literature, which models bilateral trade flows as a function of geographic distance (Frankel and Romer 1999, Anderson and Van Wincoop 2003). We build on recent work by Feyrer (2019) that exploits differential changes in the cost of air and sea shipping to derive exogenous and time-varying measures of trade at the country level. While air freight has become cheaper over the last 60 years, the cost of sea shipping has not changed nearly as much (Hummels 2007). This implied a larger decline in the effective distance between country pairs with similar sea distances, but shorter air routes (such as Japan and Germany) as compared to country pairs with similar air and sea distances (such as Japan and Australia).
Since the change in shipping costs has been rather uniform across the globe, its differential effect on bilateral trade flows can be largely attributed to geography, and not to country-specific economic or political dynamics. As in Feyrer (2019), we derive (time-varying) trade elasticities with respect to air and sea distance, and we use them to predict bilateral trade flows across countries and over time. Aggregating predicted bilateral trade at the country-year level, we recover a time-varying, geography-based predicted measure of trade with democratic and non-democratic partners.
Our findings
Using predicted trade as an instrument1 for actual trade, we find that individuals who grew up when their country was trading more with democratic partners are indeed more supportive of democracy at the time of the survey. Mirroring the effects on citizens’ beliefs, trade with democracies has a large, positive impact on countries’ democracy scores. We present these results graphically in Figure 2, plotting the relationship between trade with democracies, and citizens’ attitudes (Panel A) and countries’ democracy scores (Panel B). On the other hand, exposure to trade with autocracies has no effect on either individuals’ attitudes or countries’ democracy.
Figure 2. The effects of trade with democracies on citizens’ attitudes and democracy scores
Notes:
In Panel A: The y-axis reports individuals’ support for democracy; the x-axis reports the log of the average trade with democracies to GDP ratio during an individual's impressionable years.
In Panel B: The y-axis reports a country’s democracy score; the x-axis reports the log of trade with democracies to GDP ratio.
In both panels, the red line refers to the slope of the (with associated standard errors, clustered at the country level).
According to our results, doubling trade with democracies increases an individual’s support for democracy by 0.58 points on a 1 to 4 scale. This is similar to the difference in attitudes towards democracy between Mexico and Norway, or that between Philippines and Italy. At the country level, our estimates imply that increasing trade with democratic partners by 80% raises the democracy score by around 4 points on a scale from -10 to +10. This is equivalent to the gap between Malaysia and Canada in 2010, or that between Turkey and Senegal in 2015.
Consistent with a large literature in economics (Eichengreen et al. 2020, Giuliano and Spilimbergo 2022, 2023), the effects of trade with democracies on citizens’ attitudes can be represented by an inverted U-shaped curve across age cohorts. The effects are strongest among individuals exposed during their impressionable years, and become weaker and gradually disappear for those exposed to trade with democracies at younger and older ages. This trend is presented in Figure 3, which reports the estimated effects of trade with democracies measured over the age window of an individual. At the same time, trade with democracies promotes the accumulation of trade-induced democratic capital over an individual’s lifetime, in a way that is similar to the effect of exposure to own democracy, identified in previous work (Persson and Tabellini 2009, Acemoglu et al. 2021).

Notes:
In Panel A: The y-axis reports individuals’ support for democracy; the x-axis reports the log of the average trade with democracies to GDP ratio during an individual's impressionable years.
In Panel B: The y-axis reports a country’s democracy score; the x-axis reports the log of trade with democracies to GDP ratio.
In both panels: i) The figure plots two-stage least square (2SLS) coefficients (with corresponding 95% confidence intervals) on exposure to trade with democracies, defined as the log of the average trade with democracies to GDP ratio during the age window reported on the x-axis. ii) The dependent variable is an individual’s support for democracy. iii) All regressions partial out (or eliminate overlaps with): exposure to trade with autocracies; individual characteristics such as gender, education, and income deciles); democratisation waves; and, country by survey-year and birth-year fixed effects. iv) Standard errors are clustered at the country level. v) The blue diamond corresponds to our preferred specification (the ‘impressionable years’ or the 16-24 age window).
Our interpretation of these results is that trade with democracies improves views about democracy among citizens of autocratic regimes, and supports the flow of democratic capital from more to less democratic countries. In line with this idea, our findings are driven by the effects of trade on initially autocratic countries.
Moreover, democratisation is more likely to occur when countries trade with democratic partners that have a longer experience with democracy, grow faster, and spend more on public goods. This pattern suggests that successful democracies may become ‘role models’ and change the perceived desirability of democracy among citizens of non-democratic countries. Consistent with cultural similarity facilitating the transmission of norms, the effects are also larger when trade occurs with democracies that are culturally closer.
Mechanisms of democratisation
We test whether the transmission of democracy occurs through imports or exports (or both). On the one hand, by conducting business in democratic countries, exporters in autocratic regimes might appreciate the value of democratic institutions. On the other hand, imports of specific goods might provide citizens of autocratic countries with a signal about the (perceived or actual) desirability of democracy. Our evidence is more consistent with the latter channel: we find that only imports foster the spread of democracy across countries. Furthermore, the effect of trade with democracies is driven by partners that export higher quality goods, and account for a larger share of a country’s trade in institutionally intensive, cultural, and consumer goods, and in products that entail more face-to-face interactions and higher levels of bilateral trust. These are precisely the types of goods that can signal the characteristics of democracy and embed democratic values.
We also consider additional mechanisms, which might complement our preferred one. First, we document that these results are unchanged when controlling for the average democracy score of the country during both the impressionable years and an individual’s lifetime. This suggests that our findings capture citizens’ exposure to democracy in other, rather than in their own, countries. Second, we provide evidence against the possibility that trade with democracies fosters the process of democratisation by favouring economic development or human capital accumulation. Third, we show that trade with democracies does not favour the emergence of democracy by strengthening the middle class or increasing income inequality. Finally, we document that the results cannot be explained by democratic partners’ pressure, or by increased probability of signing preferential trade agreements (PTAs).
Conclusion
The evidence described thus far suggests that goods trade plays an important role in the process of democratisation. In our conclusion, we explore several non-trade components of economic integration. We show that trade with democracies is not correlated with migration, foreign direct investment, students living abroad, book translations, and the presence of large US corporations. Exploiting a discontinuity in air distance to predict when countries are connected through direct flights as in Campante and Yanagizawa-Drott (2018), we also provide suggestive evidence that our results cannot be mainly explained by business travel. However, this does not rule out the possibility that the effects of trade in goods are complemented by those of other factors, including the flow of people and ideas.
At a time when economic integration is declining and trade is becoming increasingly fragmented along institutional and geopolitical blocs, our findings might have important implications for the future of democracy. In particular, they suggest that these recent trends may not only have economic consequences, but might also influence countries’ institutional and political development.

Notes:
- An instrumental variable (or instrument) is used in empirical analysis to address endogeneity concerns. The instrument is correlated with the explanatory factor (that is, actual trade) but does not directly affect the outcome of interest (citizen’s attitude to democracy and countries’ democracy scores), and thus can be used to measure the true causal relationship between the explanatory factor and the outcome of interest.
