Abstract
Although a large empirical literature seeks to explain the effect of financial development in promoting economic growth, there is surprisingly little evidence for the impact of political institutions on the growth–finance relationship. This paper finds that political institutions condition the effect of financial development on economic growth. Using a dynamic panel estimator and a sample of 78 developing and emerging economies for the years 1982–2011, the paper investigates the impact of democracy on the relationship between financial development and economic growth. The paper finds that democracy does not enhance the effect of financial development on economic growth. This finding is consistent with a view that democracy can be captured by political elites or other special interests in developing and emerging economies, where institutions are relatively weak.

Notes
These potentially omitted fixed factors are cross-country differences in geography, colonial heritage, and other historical factors that jointly determine the interaction between financial development and democracy and growth.
The data on debt to GDP ratio have extensive gaps for most of the countries in the sample: To maintain the dataset, the paper uses debt to GNI ratio. But the main focus of this paper is the impact of democracy on the growth effect of finance.
As \(T > 15\) the bias becomes negligible and converges to 0.
Studies on the finance–growth relationship use 5-year averaged data, and do not consider this additional source of bias.
This number is computed: \(0.5(0.17) + (-0.18 \times 0.15 \times 0.50\)) for China; Rica.
With 5-year averaged data, the estimates are very similar to columns 1 and 3. The estimates for liquid liabilities, Pol2, and the interaction term in column 2 are qualitatively similar, though they are statistically insignificant at conventional levels with averaged data. Column 4 estimates are different with averaged data, but this is not surprising, as Aghion et al. (2005) and Levine et al. (2000) find that private credit by deposit banks is the most robust predictor of growth.
According to the private interest view of financial deepening, ‘politicians do not intervene into the financial system to further public welfare but to divert the flow of credit to politically connected firms’ (Beck 2013: 19).
Acemoglu et al. (2008) use the Freedom House Political Rights Index as their main measure of democratic political institutions to investigate the modernization hypothesis. Cavallo and Cavallo (2010) use the Polity2 subindex of democracy to examine the impact of democracy on the growth effect of crises.
Five-year averaged results are similar to fifth year data for the main estimates, and the results for the control variables are stronger with 5-year averaged data. But, again, we prefer our data to 5-year averages, because of the additional serial correlation it introduces in the regressions.
Data on total population are from the World Bank, World Development Indicators.
Data on remittances are from the IMF and include: current transfers by migrant workers and wages and salary earned by nonresident workers.
Gross capital formation is from the World Bank, World Development Indicators.
