Corruption and Economic Growth in the Balkan Countries

This paper examines the effect of corruption on public debt and economic growth. Empirical analysis verifies the channels that lead to an increase in the public debt, such as a rise in government spending, informal economy, infrastructure spending, always having a budget deficit financed through debt. The underlying hypothesis is that debt has a negative economic consequence in a country and austerity policies have more effect on countries with consolidated finances, while in developing countries such as Albania often bring an even higher growth of public debt. The final objective of this paper is the empirical verification of the idea that in developing countries, such as Albania and Balkan countries, public debt and corruption are inhibitors and deleterious for the economic growth.


Literature Review
The literature gathers a common idea, which argues that a constant growth of public debt reduces the economic growth. (Reinhart & Rogoff, 2010;Panizza & Presbitero, 2014;Pattillo et al., 2002). Rubin et al., (2004) show that public debt does not only affect directly the economic downturn, but it also influences the investors by making them more cautious, because a state with a high public debt may not be able to repay debts to creditors. As a consequence, there will be an outflow of investors due to this debt, which will cause instability in the financial market.
Developing countries such as the Balkans must be cautious regarding the continued growth of the public debt, because not only will it not affect the economic growth, but it will also turn out to be inefficient for the development objectives (Chuhan & Thomas, 2007).
The risk is higher when public policies are used for major investments in infrastructure to stimulate growth. This encourages corrupt behavior, which widens easily as a group (Tirole, 1996). The expansive corruption has negative effects on the cost and quality of investments and supports distortions in fiscal payments and growth of an informal economy (Friedman et al., 2000;Kaufmann, 2010).
According to Skidmore (1996) one of the many forms corruption becomes present is nepotism in the state administration, which touches even public hospitals where directors choose their own people or friends.
Similarly, in Albania it is quite often to see the majority of the public administration overflown with unskilled people purely because they are paying, are militants or close relatives of policymakers. Friedman et al. (2000) demonstrates that corruption is accompanied by a rise of informal activities and inefficiencies in tax collection, reducing thus, the fiscal revenues, due to fiscal evasion. It is usually the least corrupt governments the ones that tend to hold a high fiscal pressure. Johnson et al. (1997) says that fiscal evasion reduces fiscal revenue which is accompanied by a lower government's capacity to provide public goods and services. Dreher & Schnëider (2010) reveal in their study that there is no established relationship between corruption and the informal economy. They confirm that corruption and the informal economy are somewhat verified in low-income countries, while in high-income countries no such relationship exists.
According to the abovementioned authors, the widening of the informal economy in developing countries positively contributes to the GDP growth.
In the study of Fiorino et. al. (2012) corruption can hinder competition and create delays in submitting documentations. As a result, it can lead to an increase of public service costs and notably reduce the investments and economic growth.
North (1990), speaks how an efficient judicial system which respects contracts can be an important factor in the economic performance. The security that comes for property rights, benefits and patents can significantly reduce incentives to invest, innovate and buy technology from abroad. Mauro (1995) adds that corruption leads to the formation of layers that hinder the uniform development of the population by increasing inequality, eliminating the middle class of the population and reducing total growth; the rich become richer and the poor become poorer. This also brings about the reduction of economic growth in general.
Other studies have shown that the lower the perceived corruption (10-30), the higher the economic growth will be for developed countries (2%). Whereas for corruption that catches levels (60-70), the growth rate is zero or negative.

Findings
The Balkan countries we have taken into consideration for the empirical analysis are those part of EU such as Croatia, Romania, Bulgaria, Slovenia and countries aspiring to become members of EU such as Macedonia, Serbia. We have excluded Kosovo and Montenegro because of the lack of data as these are new countries that have only recently gained their independence. The first hypothesis is the one we raised in the analysis for Albania which says that good governance indicators are important for the economic growth of a country. This is based on the idea that these indicators are as important as corruption given that if they improve, corruption decreases as well.
The second one is that membership in the EU would positively help reducing corruption and increase the good governance indicators. This hypothesis takes place from the idea that Europe will impose strict rules so that politicians will no longer be able to misdirect public investments for corrupt motives, misuse public funds or choose unqualified people to work for the public administration. It is interesting how all of these countries demand the economic development to come from outside rather than internally.
If we look at the empirical models we have taken GDP growth as a dependent variable and Control of Corruption, Rule of Law and Government Effectiveness as explanatory variables. The software we have used continues to be Gretl.
The empirical model will be OLS and we will correct for heteroskedasticity. As a time series we have chosen the 15-year period from 2001-2016. We have not chosen a lot of years as all of our indicators are only estimates and as such the credibility of our paper would be low.
The number of observations is low, therefore we realize that our results are reliable but not 100%. Additionally, we specify that GDP is a complex indicator that can be influenced by a relatively high number of factors. Whereas, the other explanatory variables considered do not necessarily stimulate the growth, but they serve as as a way to not halt it and increase credibility and attractiveness towards foreign investors. Additionally, a high good governance indicator means that a country would be more able to repay its debts and therefore helps the country to have a relatively low borrowing rate.
The first country to be considered will be Croatia, followed by Slovenia, Romania and Bulgaria, and then Serbia, Bosnia & Herzegovina and Macedonia.  When looking at Croatia, Control of Corruption has a positive effect although the coefficient is quite small. The results show that the Government Effectiveness and Rule of Law negative effect on the economic growth. The stricter the law, the lower are the chances of entrepreneurs to engage in new investments, especially in sectors that could hurt or pollute the environment. This effect is logical from an economic point of view.
As far as it regards the negative effect of Government Effectiveness, it is less intuitive. We could argue that sometimes abuses can stimulate growth in developing countries. Croatia has recently joined the EU, which has most probably affected the businesses adapting to the changes the public institutions have been going through to become part of EU. However, we could always say that these indicators are estimates and can not always be taken as accurate.
The next linear empirical OLS model is the one of Slovenia, which is one of the most developed countries of the Balkans. We can notice that there is a high positive impact that Control of Corruption and Government Effectiveness have on the GDP growth with coefficients of 0.2895 and 0.2028 respectively. The standard error is relatively low and R 2 quite high.

Slovenia
Surprisingly, the impact of Rule of Law is negative. Law enforcement having a negative effect on the GDP growth is not intuitive, but it does have some grounds in the neo-liberalists theories, which support a free economy that has few interventions from the state. according to them if a country implements excessive controls and strict regulation it can substantially hurt the economy.
The rest of the analysis will be based upon the countries of the Western Balkans that are still aspiring to become part of the EU and are considered to have the highest level of corruption amongst Europe. Imagine if there was the possibility to built a factory that has inefficient cheap filters and consequently pollutes the environment. This can only be achieved through the use of corruption. However, it leads to the creation of more jobs, decreases unemployment and leads to a growth of the economy regardless of the negative effect on the environment and long term economic growth. The impact of Government Effectiveness is also negative, based on the abovementioned reasoning. The empirical model for Macedonia show a relatively smaller negative impact of Control of Corruption in the GDP growth. Given that Macedonia is a developing country, we believe the reasoning is the same as the one we mentioned for Serbia. The coefficients for Government Effectiveness and Rule of Law are positive, yet statistically insignificant. However, the relatively high R 2 shows the model is statistically significant.

Conclusion
The analysis showed the negative correlation that exists between corruption and economic growth. If we look closely at a country's economic performance, public debt, corrupton index and indeces of the governance indicators we can infer that all of these developing countries's politicians have pushed towards investments financed by debt in sectors where the possibility for corruption has been higher. Hence, they would need a good management of the public debt so that the public finances are not hurt. Most of these countries have all the resourses needed for a developed country, they have had high economic margins throughout the years, therefore a decrease in corruption and improvement of the government performance would be enough to generate rapid and high economic growth.
In conclusion, we can indicate that the economic growth and convergence of a country aspiring to reach the average level of the EU countries is directly related to the reduction of Control of Corruption, improvement of Government Effectiveness, the Rule of Law and Political Stability.
