ACKNOWLEDGEMENTS
First, I would like to express my deepest appreciation to my supervisor,
Professor Sử Đình Thành, for his lectures as well as coaching me while I performed
this research. Without his instructions and persistent support, this dissertation would
not have been possible.
Second, I would like to thank all UEH’s lecturers who instructed me in my
research methods courses during my time as a Ph. D. student in the University of

Abstract:
This study runs a co-integration and Granger causality tests that corroborate
the existence of long-run co-integration linkages of public finance and economic
growth and a bi-directional causal correlation between tax revenue and government
expenditure. This finding suggests that to control deficits, a government’s decisions
on collecting taxes and government expenditure should be simultaneous. To verify
the effects of governance represented by control of corruption on modifying the
relationship between public finance and economic growth, this study applies a
seemingly unrelated regressions model for the dataset, followed by a robustness
check using a corruption perception index developed by the Transparency
International organization. Measuring public finance by two factors: total tax
revenue and general government expenditure helps this study to confirm the results,
which reveal that the governance has a positive role in the economy. Additionally,
the interaction between governance and tax revenue or government expenditure
affects economy diversely depending on the different economic groups of
developing and developed countries1. For instance, in developing countries, the
interaction between public finance and governance always becomes a beneficial
factor for growth. While in developed countries, this interaction does not have any
meaning with taxation. Therefore, it may increase the efficiency of government
expenditure only. On the first side, the findings also suggest that developing
countries should focus on governance in anti-corruption to increase the
effectiveness of public finance and promote their economic growth. On the other
hand, developed countries should make the decision on public finance separately
with control of corruption.
In this study we call the “developed countries” are high-income countries, which were classified by World
bank and determined as those with a GNI per capita, computed using the World Bank Atlas method. On 1
July 2015, high-income countries gained more than $12,736. This study also calls the “developing countries”
are those countries were classified by World bank as seen as below. Low-income economies are determined
as those with a GNI per capita of $1,045 or less in 2014; Lower-middle-income economies are those with a
GNI per capita of more than $1,045 but less than $4, 125; and upper-middle-income economies are more
than $4,125 but less than $12,736.

INTRODUCTION
1.1.
Research background
1.1.1. An overview of the status of global economies in the period 1996–
2016
During this period, the global economy witnessed the financial crisis
that arose when the real estate bubble exploded in the US in 2007, driving the
US financial crisis and influencing production and exports in numerous
developing countries. However, the World Bank’s report said that in 2016, the
economy’s growth recovery has rebounded (see table 1.1).

From figure 1.1, we can see that there is a difference in income per
capita between 1996 and 2016 in developed countries. The maximum income
per capita is more than 13.8 times the minimum in 1996. By 2016, this gap has
declined to only 6.5 times. In 1996, Norway had the highest income per capita
at more than 73,626.16 US dollars. In contrast, Latvia had the lowest at almost
5,321.397 US dollars. In 2016, Norway still had the highest GDP per capita,
which was about 90,344.41 US dollars. However, the Seychelles had the
lowest income per capita (only 13,963.59 US dollars of GDP per capita).
Additionally, most developed countries collected more tax and spent less. In
1996, Norway’s tax revenue as a proportion of GDP was nearly 53.5 percent,
while its expenditure was only 47.5 percent. An interesting point is that
Latvia, with the lowest income per capita, also collected less tax (36.38%) and
spent more (37.03%). Norway continued to maintain its tax revenue
proportion at more than 53 percent of GDP in 2016.

There is a large gap (152.43 times) between the highest and lowest
GDP per capita in developing countries in 1996. At about 30,333.74 US
dollars, Islamic Republic of Iran had the highest income per capita, while
Ethiopia remained at the bottom with only about 199.005 US Dollars. Islamic
Republic of Iran collected tax revenue of 20.165 percent of GDP and spent
more than 21.08 percent of GDP. In contrast, Ethiopia collected only 14.86
percent of GDP in tax revenue and spent 18.79 percent of GDP. In 2016, the
gap between the highest and lowest GDP per capita in developing countries is
lower than in 1996 at about 26.68 times. Russia remained at the top with about
11,099.17 US dollars per capita, while Madagascar had only 416.0027 US
dollars per capita. Russia increased their tax revenue proportion more than
1.02 percent compared with 1996, however this country spent lower than 1996
(see figure 1.2).

1.1.2. The differences of public finance and growth between developed
and developing countries
a)
Growth rate and stability in economies
Figure 1.3 indicates that developed countries maintain stability in their
economies better than developing countries.

b)
Tax revenue, government expenditure, and control of corruption
Tax revenue is an important component of revenue for most
governments. While most developing countries collected less in taxes than
developed countries, they spent more, and their economies grew more rapidly
from 1996 to 2016 (see figure 1.5 ).

Figure 1.4 shows the trend of spending more and fast trend of economic
growth in whole 82 countries.

per capita for 44 developing cuntries in 1996-2016

Through figure 1.5, we can observe that the rapid economic growth
trend in developing economies is the same as that of the whole sample.

GDP per capita is gross domestic product divided by midyear population. The World Bank
considered that GDP is the sum of gross value added by all resident producers in the economy plus
any product taxes and minus any subsidies not included in the value of the products. This calculation
of GDP is without making deductions for depreciation of fabricated assets or for depletion and
degradation of natural resources. Data are in constant 2010 U.S. dollars.
