Recent studies appear to show that democracy has no robust association with economic growth. Yet all such work assumes that the causal effect of democracy can be measured by a country's regime status in a particular year (T), which is correlated with its growth performance in a subsequent period (T+l). The authors argue that democracy must be understood as a stock, rather than a level, measure. That is, a country's growth performance is affected by the number of years it has been democratic, in addition to the degree of democracy experienced during that period. In this fashion, democracy is reconceptualized as a historical, rather than a contemporary, variable—with the assumption that long-run historical patterns may help scholars to understand present trends. The authors speculate that these secular-historical influences operate through four causal pathways, each of which may be understood as a type of capital: physical capital, human capital, social capital, and political capital. This argument is tested in a crosscountry analysis and is shown to be robust in a wide variety of specifications and formats.

Elias Papaioannou and Gregorios Siourounis and Dani Rodrik and Romain Wacziarg find a relationship between episodes of democratization (if sustained) and growth rates in subsequent years, though they make no claims about the effect of democracy per se on growth performance; see Papaioannou and Siourounis, “Democratization and Growth,” Working Paper (London Business School, October 2004); and Rodrik and Wacziarg, “Do Democratic Transitions Produce Bad Economic Outcomes?” (Manuscript, December 2004). Barro finds that “growth is increasing in democracy at low levels of democracy, but the relation turns negative once a moderate amount of political freedom is attained”; , Barro, Determinants of Economic Growth (Cambridge: MIT Press 1997). A few recent studies find a positive overall relationship between democracy and growth, but this is not the standard finding. These recent studies include Bhalla, Surjit S., “Freedom and Economic Growth: A Virtuous Cycle?” in Hadenius, Axel, ed., Democracy's Victory and Crisis (Cambridge: Cambridge University Press 1997); and Leblang, David A., “Political Democracy and Economic Growth: Pooled Cross-Sectional and Time-Series Evidence,” BritishJour-nal of Political Science 27 (July 1997).

46 Among extant studies of democracy and growth we have found only a few that approach the concept of democracy over time, for example, Weede, Erich, “Legitimacy, Democracy, and Comparative Economic Growth Reconsidered,” European Sociological Review 12 (December 1996); and we have found none that stretches back to encompass the entire twentieth century.

49 Correlations between Polity2 and other democracy indices (introduced below in the text) are as follows: “Political Rights” (Freedom House) = -.85; “Liberal Democracy” (Bollen) =.92; “Democracy index” (Vanhanen) = .85.

52 We see no reason to suppose that a longer period of measurement—which might, in principle, stretch back to 1850—would alter any of the findings presented here.
53 This recoding affects the following countries: Albania (1900–1912, Ottoman Empire), Andorra (1900-present, France), Armenia (1900–1990, Russia/USSR), Azerbaijan (1900–1990, Russia/USSR), Belarus (1900–1990, Russia/USSR), Bosnia-Herzegovina (1908–17, Austria-Hungary; Yugoslavia 1929–91), Croatia (1900–1917, Austria-Hungary; Yugoslavia, 1929–91), Czech Republic (1900–1917, Austria-Hungary), Slovakia (1900–1917, Austria-Hungary), Estonia (1900–1916 and 1941–90, Russia/USSR), Finland (1900–1916, Russia), Georgia (1900–1990, Russia/USSR), Iraq (1900–1917, Ottoman Empire), Palestine/Israel (1900–1917, Ottoman Empire), Kazakhstan (1900–1990, Russia/USSR), Kyrgyzstan (1900–1990, Russia/USSR), Latvia (1900–1917 and 1941–90, Russia/USSR), Lithuania (1900–1917 and 1941–90, Russia/USSR), Macedonia (1922–90, Yugoslavia), Moldova (1900–1945, Romania; 1946–90, USSR), Mongolia (1900–1920, China), Bangladesh (1947–71, Pakistan), Slovenia (1900–1917, Austria-Hungary; 1929–91, Yugoslavia), Syria (1900–1917, Ottoman Empire), Tajikistan (1900–1990, Russia/USSR), Turkmenistan (1900–1990, Russia/USSR), Ukraine (1900–1917 and 1920–90, Russia/USSR), Uzbekistan (1900–1990, Russia/USSR), and East Timor (1976–99, Indonesia).
54 In an alternative coding of this variable we assign a score of -10 (the lowest score on the Polity2 variable) to missing data from preindependence years (rather than the usual default score of 0). The historical variable constructed from this alternative coding procedure shows virtually identical results to those displayed in Table 1. Thus, in fixed-effect tests it does not matter what sort of coding procedure is used to fill in missing data from years prior to a country's independence. These scores, the reader will recall, matter only for the construction of the stock variable; they are not observations in the data analysis (no growth data is available for periods prior to independence).

74 We interpolate missing values for illiteracy, life expectancy, and population growth in order to maintain a consistent sample (failing to do so would have significantly reduced the sample size and perhaps biased our results).
75 See Papaioannou and Siourounis (fn. 1); Przeworski et al. (fn. 1).
76 An additional test—not shown—divides the sample into (1) observations where a country registers a “positive” democratic stock (>0) and (2) observations where a country registers a “negative” democratic stock (<0). This tests the possibility that our aggregate results are being driven by influential groups of long-term democracies or long-term autocracies. Reassuringly, the coefficients and standard errors for our key variable, democracy stock, are virtually constant across these two subsamples, suggesting that there is a relatively consistent democratic growth effect for deep autocracies and deep democracies.

78 Temporal delays and nonlinear causal relationships are possible only if one moves beyond the realm of interests, opinions, and coercion tout court. For example, if a person does not fully realize his or her true interests then some delay between cause and effect might be anticipated.
