Abstract
In the last two decades, numerous fiscal crises have profoundly affected the trajectories of
many nations. Yet, the susceptibility to such crises has not been uniform across countries: with
many reaching different levels of severity and frequency of fiscal disruptions (Medas et al., 2018;
Petrova et al., 2011).
Understanding the varied factors that contribute to fiscal resilience is crucial for guiding
policy interventions. In this context, a growing body of research suggests that the economic
complexity of a country plays an important role in its stability and resilience. Economic
complexity, assessed through methods that analyze the geographic distribution of economic
activities, serves as an indicator of a nation's productive structure (Balland et al., 2022; Hausmann
et al., 2014; Hidalgo, 2021; Hidalgo and Hausmann, 2009). This structure captures multiple
economic, social, and environmental factors that should be critical for an economy's stability and
its ability to withstand fiscal shocks. Indeed, countries with higher complexities have been found
to be less fragile to fiscal crises (Gomez-Gonzalez et al., 2023b), have lower volatility in economic
growth (Güneri and Yalta, 2021; Maggioni et al., 2016), have lower inflation (Al Marhubi, 2021),
and lower sovereign yield spread (Gomez-Gonzalez et al., 2023a; Özmen, 2019).
But all the research on the ability of economic complexity to explain fiscal outcomes comes
from using international trade data (Hausmann et al., 2014). While trade data has been the standard in international comparisons of productive structure, a more recent approach suggests a
multidimensional method to economic complexity (Stojkoski et al., 2023). The idea behind this
approach is that relying solely on trade data can obscure vital aspects of an economy’s structure,
particularly in innovative activities such as technological production and research output. By
integrating data on these activities, the multidimensional approach captures a fuller spectrum of
activities, thereby providing a more accurate assessment of the complexity of a country and its
impact on economic outcomes.
Here, we explore the role of multidimensional economic complexity, captured through two
dimension: trade and research1, on the likelihood of a country to mitigate a fiscal crisis. By
utilizing hazard duration analysis and a comprehensive dataset covering 131 countries and over
230 fiscal crisis episodes from 1995 to 2021, we find evidence that multidimensional economic
complexity significantly reduces the probability of experiencing a financial crisis. Namely, our
analysis suggests that the individual dimensions of trade and research alone are not robustly related with the likelihood of a country to experience a fiscal crisis (see Table 1, columns 1-3, 6-8). In contrast, it is their interaction that has the largest explanatory power: countries that score highly in both the trade and research dimension have the lowest chance to have a fiscal crisis (Table 1,
columns 4-5). Interestingly, we also find that having a developed economy in one dimension
actually has a positive impact on the chance for a fiscal crisis. This could be potentially a result of
neglecting other dimensions – a robust economy should be complex in multiple dimensions. These
results are statistically robust when including additional controls that may affect the chance of a
fiscal crisis: the regulatory quality of the country, the interest expenses as a % of GDP, the real
GDP growth, and the rule of law.
Our findings underscore the importance of the multidimensional approach to economic
complexity in structural resilience and safeguarding against fiscal instability.
