In this study, we aim to put forth the tax wedge case that affects both the labor costs and the proposed investment level that also means economic growth through the public decision-making process in an analytical framework. Given that the tax wedge is the proportional difference between the tax paid by a taxpayer worker and the cost to the employer, it is understood that the effect levels also create different differential effects. In this context, it is necessary to question the analytical relationship between the tax wedge and the tax burden. The relationship between this systematic-analytical structural relationship and economic growth also means examining possible externalities in their impact levels. It seems that this effect on OECD countries reveals significant differences according to the development levels of the states. Besides, the breaking point where these differences are substantial in terms of our determinations is the tax burden of nations, and it is understood that the proportional changes in the tax wedge are directly affected by this financial fact. In addition, the fact that OECD countries also have different tax burdens, the differences between tax systems in practice also differentiate the analytical relationship between the tax wedge and tax burdens. However, the measures related to the deviations of global financial and economic relations between OECD countries reveal that possible analytical differences between tax wedge and tax burdens have tried to be overcome via the fundamental systemic financial restructures in recent years.

In this study, we aim to determine the extent to which the average investment limits affect the average tax burden under the OECD. It appears that international investment limits in OECD countries are affected by three components. Undoubtedly, one of these is the average tax burden under the OECD. Other components are the average debt ratios of governments and countries' real growth movements on economic growth, which affect the global average measure of investment services. It is observed that the changes in investment options in OECD countries show significant differences according to the average tax burdens of the countries and affect the investment limits significantly. This phenomenon put forth a significant change effect on investments as an average of criteria effect, and this approach makes it meaningful to conduct a tax burden-based study. Since the tax burden phenomenon in countries varies in terms of domestic and foreign debt of countries and is directly related to growth rates. The fact that changes in the average tax burden of OECD member countries affect investments reveals that it is dependent on the tax burden, the GDP of the relevant countries and the average debt burden of the OECD countries. Domestic and public foreign debt options of these countries directly affect the OECD's average investments. It shows that this influence analytically increases the negative criteria based on investments in these countries concerned.

In this study we aim to put forth the important of consumer confidence indicators that are related to emerging markets, which effect on directly some macroeconomics alterations especially for OECD countries. The developing countries’ differences as OECD’ countries cause the different effects on the emerging markets that are in the different developing levels connected with different countries. The problematical structure cause to bring out in the two negative structural locations for reaching OECD’s general financial targets that mean to express the unity cooperation soul. In this context, two important financial effects of consumer price index in OECD countries can be emphasized. The first one, which is also the weighted topic of our study, is the structural changes that can be expressed by financial weakness and fragility. The other one is how and to what extent developing countries have been affected by these changes. In particular, developing underdeveloped countries display a structural process in which changes in financial indices change with changes in consumption indices in periods of financial crisis. This phenomenon leads to differentiation of these considered common policies within the scope of the OECD and it brings different levels of financial impact to the agenda.

In this study, we aim to attempt to analysis the
