Resumen: Las instituciones han sido ampliamente estudiadas como impulsoras del crecimiento económico. Los países Latinoamericanos en el siglo XXI han tenido un incremento en el intervencionismo del Estado; sin embargo, la región presenta un promedio de la tasa anual de crecimiento alrededor de 3.31 por ciento en los primeros diecisiete años. Esta investigación está tratando de establecer la causalidad entre la libertad económica, producción petrolera y colectivismo con el crecimiento económico. En este informe de investigación en progreso, mostramos los primeros resultados de nuestro diseño experimental, el cual demuestra la importancia de estas instituciones. Utilizando estadísticas básicas de crecimiento, concluimos que los países que redujeron su libertad económica experimentaron aproximadamente una tasa de crecimiento de 1.81 puntos porcentuales menos que aquellos países que no redujeron la libertad económica, este resultado es estadísticamente significativo al 1%. En promedio, nuestros hallazgos sugieren que en Latinoamérica durante el período de estudio (2001-2017), los países no-petroleros disfrutaron en promedio de una tasa anual de crecimiento aproximadamente 1.14 puntos porcentuales mayor que los países petroleros de esta región. Sin embargo, los países más-colectivistas crecieron a una tasa anual promedio que superó en 0.48 puntos porcentuales a la de los menos-colectivistas. Finalmente, estimamos un modelo de diferencias en diferencias, para ello utilizamos MCO, y variables instrumentales generadas controlando por efectos fijos por país y aplicando una serie de estimadores para determinar el efecto de la libertad económica en estos países. Nuestros resultados, estadísticamente significativos, sugieren que los países Latinoamericanos que pierden libertad económica crecen a una menor tasa que el resto de los países.

Abstract: Institutions have been widely studied as triggers of economic growth. Latin American countries in the XXI century have shown an increment in State interventionism; nevertheless, the region exhibited an average annual growth rate around 3.31 percent in the first seventeen years. This research is trying to establish the causality between economic freedom, oil-production, and collectivism with economic growth. In this research in progress report we show early results of our experimental design, which demonstrates the importance of these institutions. Using basic statistics on growth, we conclude that countries that reduced their economic freedom experienced an economic growth of about 1.81 percentage points lower than those countries that did not reduce it, at 1% of significance level. On average, our findings suggest that in Latin America during the analyzed timeframe (2001-2017), nonoil producer countries enjoyed an average annual economic growth rate of about 1.14 percentage points higher that the economic growth experienced by oil-producers. Interestingly, more-collectivist countries grew 0.48 percentage points more than less-collectivist. Finally, we estimated a difference-indifferences model using OLS, and generated instruments (Lewbel, 2012; Lewbel, 2018) accounting for country fixed effects, and applied a variety of estimators to determine the effect of economic freedom in these countries. Our results, statistically significant, suggest that Latin American countries that lose economic freedom grow at a lower rate than the rest of the countries.

Scholars are interested in economic growth because of its relationship with prosperity, quality of living, and the human well-being (Pritchett, 2000). Nevertheless, understanding and analyzing economic growth is thorny and sensitive for the many endogenous and exogenous factors that affect the performance of countries. In the literature, researchers tend to explain the great differences in the living standard among countries through small differences of economic growth for long periods of time as Pritchett (2000) defines it as “the power of compound interest, over long periods” (p. 221). Following this trend, we could state that the effect of 0.09 percent difference in the economic growth rate between Uruguay and Chile helped the latter surpass the former in terms of GDP per capita, consolidating Chile as the best performing economy in the Region with the higher standard of living in our period of analysis. Nevertheless, such as statement would rely on just the result of the economic performance and could not consider other important characteristics that countries of this region have and that could affect their economic growth.
However, the question of whether institutions could affect, positively or negatively, the economic growth is a basic concern for researchers in the field of economic growth and development that has not a general accepted answer. Many scholars support that there are two main sources of growth: (1) the addition of more inputs (physical capital and labor), and (2) innovation, technological change, or, in technical economic terms, total factor productivity. The former source of economic growth is also known as brute-force and the later was labeled smart-growth by Robert Solow who defended that smartgrowth is more important than brute-force (more inputs) in generating additions to output over time (Solow, 1956, 1957; Denison, 1962, 1967; Easterly and Levine, 2001).
Currently, there are institutional variables that have captured the attention and approach of development economists. A large body of literature suggests that such as variables have a positive and significant impact on economic growth (Acemoglu, Laibson and List, 2018). For example, the geography, the latitude and altitude of a country play a fundamental role in the economic development, showing that as northern the country is the more developed it could be (Gallup, Sachs, and Mellinger, 1999) .. Other authors support that culture and institutions can explain why some countries grow faster than others (Acemoglu et al., 2019).. Th. literature also shows that other factors could
affect the economic growth. Corruption and military violence affects negatively the economic growth, and democracy is essential for growth (Halperin et al., 2005). Political freedom has been also studied and scholars argue that it is a factor of economic growth (Bueno de Mesquita and Downs, 2005). Finally, economic freedom—an institutional variable that measures the non-interventionism of state in the economy and the capacity of private individuals to take their own economic decisions and establish transactions without the intervention of governments—has a positive and significant effect on growth (Gwartney et al. 2019).. Notwithstanding, many authors have argued that there are not reliable results to support the relation between these institutional variables and economic growth (Sturm and De Haan 2001;Doucouliagos and Ulubasoglu 2006; Sturm, Leertouwer, and De Haan 2003; Ram 2000).
On the other hand, Latin American region has had an average economic growth rate around 3.31 percent in the first seventeen years of the XXI century (Penn World Table 9.1). This is not a poor result at all because if we look at the same statistic, the last 6 years (from 2012 to 2017) the average economic growth rate decreased to 1.40 percent. In addition, these countries seem to have more common characteristics than just being in the same region, such as high degree of collectivism (Hofstede, 2001), economies that are highly intervened by governments, and high dependency on a specific commodity as crude oil and natural gas (Mora and Acevedo, 2019). Furthermore, countries of this region have experienced many social, political and economic shocks in the 21st century. Ecuador dollarized the economy in 2000 while El Salvador did it in 2001. Between 2002-2003 Venezuela, in that moment the largest oil exporter of the region, suffered a coup and an
oil-workers strike. The increment of oil price, that started around 2005-2006 marking its highest between 2011-2012, also affected the social-economic-political performance of this region if you consider that six of these countries are among the larger exporters of oil in the world.
Considering the specific uniqueness of each of these countries and the geopolitical relevance that the Latin American region has within the Americas, our research is aimed to find a reliable evidence to establish the causality of economic freedom, and other variables such as oil production and collectivism, on economic growth during the first seventeen years of the XXI century. For this, we try to determine if those countries in Latin America that reduced economic freedom—oil-producers, and/ or more collectivists—have enjoyed less economic growth than countries that did not weakened their economic freedom—nonoil-producers and less collectivists.
We divided this research in progress report in four sections. First, we present a general overview of the intent of our research, introduce the literature review, and outline the relevance and objective of our research. Second, we detail the experimental design that we are following to achieve the objective. Third, we report the results we have at this moment. Finally, we conclude and present some future research directions.
This research is trying to establish the causality between some institutional variables and economic growth in the Latin American countries. Glennester and Takavarasha (2013) explain, “Measuring causal impact requires us to compare what happened with the program with what would have happened without the program” (p. 24). For this research, the program is having the characteristic that we are interested to study (diminishing economic freedom, oil-producer, and more collectivism). Then, following the cited authors we developed an experimental design that allowed us to measure the difference of the economic growth rates between countries that have and that do not have those characteristics.
Data
The data used in this research is the expenditure side of real GDP at chained purchasing power parity in US dollars (2011) and the population size from the Penn World Table 9.1 of 18 countries for 17 years beginning in 2001. The countries analyzed are: Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Peru, Paraguay, El Salvador, Uruguay, and Venezuela. We also used data from the Economic Freedom of the World Index (EFW) published by the Fraser Institute and, from the Economic Commission for Latin America and the Caribbean (ECLAC), we obtained the information to determine whether a country is considered an oil-producer country. Finally, using Hofstede (2001) we could classify countries as “more collectivists” or “less collectivists”. In table 1, we report a brief description and the summary statistics of the data.

Description and Summary Stadistics
.Treatments
In a research with this experimental design, the definition of the treatment is very important. First, we must consider that treatment indicates that an individual was included in the program which, in this research, means that the country has the characteristic that we want to analyze. Secondly, the success of this kind of research design depends on how researchers define if an individual is considered treated or not treated (control group), (Glennester and Takavarasha, 2013).
Our research presents a straightforward definition of the treatments. We have three institutional variables of interest, then, we defined our treatments as follows:
• Economic freedom (EFW): we consider that the decrement of the score is the result of applying at least one policy that undermined the property rights and/or the possibility of making your own economic decisions. Then, if the country is a treated unit. We classified countries in the control group if they had an economic freedom score higher or equal than the previous year.
• Oil-Producer (Oil-prod): we defined a country as treated if it exports oil; otherwise, the country classifies in the control group. The quantity of oil exported is not considered, as well if the country produces but does not export, for example Chile produces but just covers barely 3% of its internal consumption, then it classifies in the control group.
• Collectivism (Collect): firstly, we classified countries as “More Collectivists” (treated) or “Less Collectivists” (control). Hofstede (2001) scores each country with a number between 0 to 100, countries closest to 0 are more collectivists. Argentina has the highest score of the region, 46, and the lowest is Guatemala with 6. If the country’s value divided by Argentina’s value was
less than 0.5 then it classified as treated unit, otherwise it classified in the control group2.
Identification Strategy
The first methodology we used was the basic statistical analysis of economic growth. For this we estimated the annual growth rate of the real GDP per capita for each country and calculated the average for the full sample and each group (treated and control). Finally, we estimate the difference between groups using OLS and following equation (1)

where is the economic growth rate of country in year , is a dummy indicating whether the country is treated or no in year . Then, is the parameter that indicates us the difference in the average growth rates between treated and control groups.
The second methodology we used was the differencein-differences (diff-in-diff). Gertler, et al (2016) explain that “the difference-in-differences method compares the changes in outcomes over time between a population that is enrolled in a program (the treatment group) and a population that is not (the comparison group)” (p.139). It has been used in research to analyze the impact of a policy (or treatment) between individuals affected and not affected by that policy (the treated and control groups). It is widely used in political science research to analyze the impact of a public policy as in Nykiforuk, et al (2019)3. Other authors have used this methodology to analyze economic and/or decision-making issues, as Mukhopadhyay (2019)4. This method has been used in papers analyzing the impact of an event or policy on economic growth as in Chen (2019)5.
Gertler, et al. (2016) explain that for an analysis of difference-in-differences the researcher should measure the outcome before and after the program in both groups the treated and control. Then we should have a dummy for the period, pre-treatment (value 0) and post-treatment (value 1). However, and following the methodology proposed by Grier, Hicks, and Yuan (2015), it is possible analyze a difference-indifferences considering other characteristic(s) in the analysis even if the sample does not have a period dummy variable. We estimated the diff-in-diff model using OLS, and the generated instruments proposed by Lewbel (2012 and 2018) to analyze the reliability of our results. The specification model estimated is represented in equation (2):

Now, is the same dummy variable we used in equation (1) for classifying the country if is treated (decreased economic freedom) or no in year . stands for the “second characteristic” and is the dummy variable for oil-producer or more-collectivist. is a vector of control variables, and the error. We used our variables Oil-prod, Collect, and for human capital the educational attainment6, as the control variables. is the diff-in-diff parameter and shows the effect of those countries that diminished their economic freedom and with the other characteristic (oil-producer or more collectivist) on the growth rate.
Basic Statistical Results
Table 2 presents the basic statistical results on economic growth. The region, represented by the full sample, had an average of the annual growth rate of around 3.31 percent. When we break our timeframe in short periods, we can see that the best performance was between 2004 and 2008, with an average annual rate of around 5.77 percent. The secondbest performing period was between 2008 and 2012 with an economic growth of around 4.63 percent. These two periods correspond to the beginning and the end of the last oil price increase. Between 2012 and 2017, the region experienced its worst economic growth, not surprisingly during these years the price of oil plummeted and political-social and economic problems were experienced in Latin America. The region seemed to be richer, at the end of the period the final average income represents around 178.25 percent of the initial average income, which could be interpreted as an improvement in the quality of living.

The EFW data suggests that those countries that reduced economic freedom experienced a lower economic growth than those which did not reduce economic freedom. If we look at the entire timeframe from 2001 to 2017, it is possible to conclude, with a 1% of significance level, that countries that reduced economic freedom had an economic growth of at least 1.85 percentage points less than those that did not hurt their freedom. When we analyzed the economic growth rates in shorter periods, this relation remains the same and our findings suggest that there is evidence that suggests that, even at 1% significance level, a reduction in economic freedom leads to a lower economic growth rate.
The average on initial and final income also seems to sign the causality that economic freedom has on the economic performance of this region. Treated units had a greater initial income than the control group, for instance, in 2001 while individuals from a country of the treated group earned $1, individuals from countries of the control group earned $0.92. Nevertheless, the final income of the control group offset the initial difference and is even larger. In 2017 while an individual from any country of the treated group earned an average of $1 individuals in the control group earned an average of $1.41.
As we stated before, this region is characterized for having six of the larger exporters of oil in the world. For this reason, any analysis of economic growth for these countries must account for the heterogeneity caused by this condition. Furthermore, another main characteristic is that all oil- producer countries in Latin American have the condition that oil enterprises are state-owned, which could hurt the potential benefits of having this scarce natural resource as public sector implements managerial decisions based more on the political benefit than in the economic utility. During the entire timeframe analyzed (2001-2017), results showed that non-oil producers enjoyed an economic growth rate at least 1.14% higher than oil-producers.
During 2004-2008, oil-producers enjoyed the highest rate of economic growth of around 7.61 percent, surpassing by 2.75 percentage points the average economic growth rate enjoyed by the non-producers (control group) at 1 percent of statistically significance. This was the result of the oil price surge experienced during those years. Nevertheless, the dependency on oil prices to promote economic growth is evident between 2012 and 2017 when oil-producers experienced a lower economic growth rate of around 3.83 percentage points, at 1% level of significance, than the non-oil-producers. The average incomes are also suggestive, individuals living in oil-producers impoverished in comparison with their peers in non-oil- producers (from almost 1:1 to almost 1:1.2).
When we turn to the last panel Collect (collectivism), we noticed that more collectivists countries (treated group) grew around 0.48 percentage points faster than the control group, but non-statistically significant, for the whole period. This relation remains in most of the short periods, with the 2001- 2004 timeframe showing the higher difference of around 3.38 percentage points at 5% level of significance. Nevertheless, if we look at the differences of incomes between groups, the gap was closed from 1:1.67 to 1:1.56, meaning that, despite individuals in less collectivist countries earn much than in more collectivists, the latest had a greater proportionally improvement.
Diff-in-Diff OLS Results
In table 3, we report the results obtained when we estimated equation (2) using OLS. The coefficient of interest, (from now, diff-in-diff), is negative and statistically significant at the 10% level, as we expected, when the variable production is included in the interaction (columns 1 to 4). These results support that in average countries that suffered a decrement in their economic freedom score and are oil-producers grew around 3.4 percentage points less than those non-oil-producers and/or that keep at the same level or increased their score of the economic freedom index. The EFW is statistically significant at 5% level and suggests that if a country decreased its economic freedom score it grew around 1.34 percentage points less than those that did not diminished their economic freedom.

When we turn to columns 5 to 8, using collectivism as the interacting term in the model, results changed. Now, the diff-in-diff shows a positive but non-statistically significant coefficient, but interestingly the dummy that captures the impact of the change in the economic freedom score (EFW) in these specifications is negative, as we expected, and improved its significance at 1% level. Despite the diff-in-diff is not significant we can assume that those countries that suffered a decrement in their score of the economic freedom grew at least 3.4 percentage points less than those that keep the same level or improved their scores. Despite results are not significant, they also seem to suggest that countries with decrements in their score and more collectivists grew at least 1.2 percentage points faster than those less collectivists, and those that maintained the same level or increased their EFW. At this point, we should highlight that Argentina, Brazil, and Mexico are in the group of the less collectivist countries, in addition, those countries are oil-producers. Furthermore, in the more collectivist group, there are four of the six highest economic growth rates of this sample, Peru, Panama, Colombia, and Ecuador[7], and then these arguments justify the results obtained.
Diff-in-Diff Generated-IV Results
In table 4, we report results of estimations of the equation (2) but using the generated instrumental variables methodology proposed by Lewbel (2018 and 2012). From columns 1 to 4, table 4, we estimated the model in column 4, table 3. Using a variety of estimators, we obtain that the diff-in-diff is negative and statistically significant at 10% level, suggesting that losing economic freedom and being an oil-producer country impacts in at least around 2.5 percentage points less in economic growth rate that those countries that do not decreased their freedom.
The EFW is still negative and statistically significant at 5% level suggesting that those countries that decreased their EFW grew around 1.1 percentage points less than those that did not decrease their economic freedom.

When the specification included collectivism as the interacting term with EFW, columns 5 to 8 in table 4, and used the continuously-updated GMM and the two-step efficient GMM estimator, columns 7 and 8 respectively, the diff-in-diff was positive and statistically significant at 5% level. These results suggest that more collectivist countries that diminished EFW grew faster at least 2.8 percentage points more than the rest of the countries. Notwithstanding, all estimations also reported at 1% level of significance that without considering the more collectivist characteristic, the fact of losing EFW means that countries grew around 3.4 percentage points less than those that do not lose freedom. All results are robust for the tests of under and over identification performed in this methodology.
The early results of our on-going research suggest and signal a potential causality between the institutional variables, that we are using, on the economic growth in Latin America. However, further research must analyze other characteristics of economic growth in these economies, such as volatility and instability.
The results that we provide in this research in progress report coincides with the available literature which stresses the positive and significant effect of economic freedom on economic growth. In addition, our statistical analysis has help us to show evidence that oil-producer countries in Latin America did not have the economic performance enjoyed by non-oil producers; perhaps the higher dependency on this commodity makes them more susceptible to shocks. However, our results differ from the empirical corpus reviewed in the collectivism characteristic. Latin America is a region where collectivism plays a fundamental role in the culture however it seems to be that this characteristic does no harm to the growth potential in these countries, but further research is needed to draw a more robust and reliable conclusion.
We used methodologies that are robust and allowed us to estimate the effect of the institutional variables of interest (economic freedom, oil-producer, collectivism), and to measure the effect of decreasing economic freedom on economic growth (while accounted for other characteristic). However, a caveat that we should make regarding our research is that there could be limitations related with our sample size. Ideally, we could include other countries, years, and variables as well as use other causal effect methodologies to establish the causation. Even thought this would help to draw a more general conclusion, a wider region or worldwide sample is not the geographical and political research interest of our investigation and such as researches have been addressed by other scholars (for example, Grier and Grier, 2018). Given this caveat, our research will continue addressing these nuances and analyzing the data following an experimental design that seems to be the path for strongly establish the causality.
