Does Institutional Quality and Economic Freedom Impact on Foreign Direct Investment? Evidence From Developing Countries

Using panel data analysis, it is an attempt to estimates the significance of institutional quality and economic freedom on foreign direct investment for a sample of 79 developing countries from 1998 to 2014. Panel unit root, pedroni residual cointegration test, vector error correction model, generalized least square (GLS), feasible GLS (FGLS), pooled OLS, random effect, fixed effect, poisson regression, prais-winsten, generalized method of movement (GMM) and generalized estimating equation (GEE) method are utilizing for estimates the importance of institutional qualities and economic freedom for facilitating foreign direct investment. VECM confirms that there is a long run relationship among the tested variables means that commensurate institutional quality and substantive economic freedom stimulates foreign direct investment. According to the OLS method ,for the institutional quality the coefficient implies that a one standard deviation improvement in political stability and absence of violence, government effectiveness, regulatory qualities, rules of law and control of corruption increases FDI by 24.6%, 31.6%, 12.8%, 23.9% and 37.7% and on the other hand for the economic freedom , the coefficient implies that a one standard deviation improvement International Journal of Accounting and Financial Reporting ISSN 2162-3082 2018, Vol. 8, No. 4 http://ijafr.macrothink.org 325 in business freedom, trade freedom, government size, investment freedom, property rights, freedom from corruption, labor freedom, financial freedom, fiscal freedom, monetary freedom increases FDI by 28.4%, 32.7%, 29.5%,22.8%, 29.0%, 36.4%,29.3%, 37.5%, 46.1% and 38.2% respectively. By using the other methods like random effect, fixed effect, poisson regression, prais-winsten and generalized estimating equation (GEE) method explores that both the institutional quality and economic freedom are influencing on FDI in the developing countries.

in the index. Each and every factor separately and independently influences the foreign direct investment.
According to the Jude and Levieuge (2013) have used a sample of 94 developing countries over the period 1994-2009 and a panel smooth transition regression (PSTR) to identify the threshold of institutional quality that influence the FDI growth effect. They discover that the advancement of the institutional framework should precede FDI attraction policies to benefits from FDI-led growth and that. Zafar Mueen Nasir and Arshad Hassan (2011) conducted a research work among South Asian countries 1995-2008 by using panel data analysis and fixed effects model and explores that there is a significant positive relationship between economic freedom score and FDI inflows.
This view, however, is disputed by the different authors like Habib and Zurawicky (2002), Li and Filer (2004), Li (2005), Henisz (2000), Moskalev (2007) and Zhu (2007). Li (2005) have argued that poor institutional quality does not necessarily mean the lack of protection. In an environment of poor institutional arrangement, MNCs strategically adjust to the local business climate and pay bribes in order to obtain business contracts (Zhu, 2007). Poor institutional arrangement may also offer enhanced investment opportunities for MNCs. In an environment of poor institutional arrangement, rent-seeking activities are pursued not only by politicians and policy makers but also by large MNCs. Relation-based systems are often controlled by powerful rulers who tend to favor big business (Li, 2005).
Yassaman Saadatmand and Jeremy Choquette (2012) accomplishing a research work among 51 African countries from 1998 to 2009 by applying panel data regression method and discover that economic freedom discourages FDI inflows to the selected African countries.
To explore the effects of institutional quality and economic freedom on FDI, the paper is incorporated with the, literature review, model specification, empirical evidence and conclusion.

Literature Review
Because of the radical transition of the business and its relevant functions, traditional determinants (wage costs, infrastructure or macroeconomic policy) of FDI is no longer hold rather less traditional determinants has become more important, like institutions or economic freedom.
According to Busse and Hefeker (2007) and Ali et al. (2010), interprets that institutions can increase and optimize not only the FDI quantity, but also their quality. Institutional quality along with the economic freedom is a significant determinant of foreign direct investment as International Journal of Accounting and Financial Reporting ISSN 2162-3082 2018 well as a noteworthy factor in economic growth (e.g., Barro, 1997;Dawson, 1998;Estrin, Bevan and Meyer, 2001;Ghura and Goodwin, 2000;Heckelman, 2000).
Different studies have argued that there is a robust relationship between non-economic factors, such as institutional quality and FDI (Busse and Hefeker 2005;Daude and Stein 2007). According to these global studies, a government"s political stability, regulatory quality, rule of law, and level of corruption have a statistically significant effect on foreign investment. On the other hand, Gwartney (2009) penetratingly determined that countries with having enormous amount of economic freedom leads higher shares of private investment in GDP, higher productivity of private investment, grow more rapidly and achieve higher levels of per capita income than countries with lower levels of economic freedom.
According to Daude and Stein (2007) demonstrates that inward FDI is deeply influenced by the quality of institutions. Through a contemplative and vigorous research work accomplish by Rodrik and Subramanian (2002) emphasized on the supremacy of institutions over other determinants of FDI which is supported by Wernick, Haar and Singh (2009) arguing that "good" political and governance institutions reduce economic and political uncertainties and promote efficiency as effective governing institutions provide the necessary legal framework for economic growth and socio-economic development. Concentrate on the Marta Bengoa, Blanca Sanchez-Robles (2003) empirical work among 18 different Latin-American countries base on panel data analysis from 1970 to 1999, find out that the host country"s economic freedom is found to be a positive and statistically significant determinant of FDI inflows.
The relationship between investment climate and private investment decisions has shown that "better political and governance institutions improve the investment climate by enhancing bureaucratic performances and predictability" (Aysan and Veganzones-Varoudakis, 2007) which reduces companies" costs of performing their business activities and economic freedom has expand the confidence level of the entrepreneur who enormously concentrate on accomplishing his business function and help to expand the economic growth and per capital income (e.g., De Haan et al., 2006;Azman-Saini et al., 2010;Compton et al., 2011). Institutional quality assists to increase the entrepreneur capacity of the local producer. Huang (2003) notes that poor institutions reduce the supply of local entrepreneurship; high quality institutions increase local entrepreneurship.
Several studies such as Bé nassy-Qué ré et al. (2007) and Busse and Groizard (2008) have stressed the potential positive role of good institutional quality in economic development, in particular as an attraction to further persuade inflows of FDI. Bengoa, Marta, and Sanchez-Robles (2003) investigated the relationship between economic freedom and foreign direct investment by using panel data of 18 different Latin American countries from the period 1970 to 1999. Empirical results illustrated that economic freedom facilitated FDI inflow and the economic growth was also found definitely related with FDI.
Institutional quality and economic freedom may not always a considering factor for FDI especially in developing countries. Sometime weak institutional quality facilitates foreign direct investment. Hausmann and Ferná ndez-Arias (2000) claim that developing countries with weak institutions can actually attract more FDI because investors sometimes prefer to International Journal of Accounting and Financial Reporting ISSN 2162-3082 2018 operate directly in unregulated environments, as the cost of engaging in more developed markets can be high.
Absorbing capacity of the host country is inevitable factors rather than the economic freedom in many developing countries. Multinational firms not just seeking the exploring resources rather also consider the availability of the human capacity that encourages them to make rigorous investment.
Using data on 80 countries for the period 1979-98 Durham (2004), have failed to identify a positive relationship among FDI , economic freedom and economic growth, based on his empirical work he advocated that the effects of are contingent on the ""absorptive capability"" of host countries.

Model Specification
This paper is mainly explores the consequence of institutional quality and economic freedom on stimulating FDI by using panel data analysis for a sample of 79 different developing countries from 1998-2014. As part of the methodological design, the basic equation is illustrated below: FDI= α 0 +α 1 PoliticalStability+α 2 Government effectiveness+ α 3 Regulatory Quality + α 4 Rules of Law+ α 5 Control of Corruption+ α 6 Businesss Freedom + α 7 Trade Freedom+ α 8 Government Size+ α 9 Investment Freedom + α 10 Property Rights + α 11 Freedom from Corruption+ α 12 Labor Freedom + α 13 Financiaal Freedom+ α 14 Monetory Freedom+ α 15 Democracy+ e t (1) Where α 0 , α 1 -α 13 are parameters to be estimated. e t is stochastic error terms assumed to be independently and identically distributed.
For measuring the significance of institutional quality and economic freedom on the incessant flow of foreign direct investment different methods have used. .
At first for indentifying whether data are stationary or not for measuring it panel unit root test is being accomplished.

Panel Unit Root Test: Levin, Lin and Chu
Levin, Lin and Chu start panel unit root test by consider the following basic ADF specification.
DY it = αY i t-1 + ∑ Pi j=1 β i t DY i t-j + X * i t δ+Ԑ i t Where, H 0 : null hypothesis as panel data has unit root (assumes common unit root process) H 1 : panel data has not unit root

Im, Pesaran and Shin
The properly standardized t* NT has an asymptotic standard normal distribution and also it was rewritten to be new t-statistics as well as can show below that: (see equation 3).
Where, W t*NT is W-statistics has been used to test panel data based on Im, Pesaran and Shin techniques. Also this technique has non-stationary as null hypothesis as well as to show below that: H 0 : null hypothesis as panel data has unit root (assumes individual unit root process) H 1 : panel data has not unit root

Fisher-Type Test Using ADF and PP-Test (Maddala and Wu and Choi)
Madala and Wu proposed the use of the Fisher (Pλ) test which is based on combining the P-values of the test-statistics for unit root in each cross-sectional unit. Let p i are U [0, 1] and independent, and -2log e p i has a χ 2 distribution with 2N degree of freedom and can be written in equation 4.
Where, P λ = Fisher (P λ ) panel unit root test N = all N cross-section -2 ∑ N i=1 log e p i = it has a χ 2 distribution with 2N degree of freedom In addition, Choi demonstrates that :( see more detail of Choi demonstrates that in equation 5).
Where, Z = Z-statistic panel data unit root test International Journal of Accounting and Financial Reporting ISSN 2162-3082 2018 N = all N cross-section in panel data Ө i -1 = the inverse of the standard normal cumulative distribution function p i = it is the P-value from the i th test Both Fisher (P) Chi-square panel unit root test and Choi Z-statistics panel data unit root test have non-stationary as null hypothesis as well as to show below that: H 0 : null hypothesis as panel data has unit root (assumes individual unit root process) H 1 : panel data has not unit root.

Hadri
The Hadri test for panel data has the hypothesis to be tested is H 0 is null hypothesis and H 1 is against null hypothesis and can show below that: H 0 : null hypothesis as panel data has not unit root (assumes common unit root process) H 1 : panel data has unit root

Panel Cointegration Test
In order to solve the spurious regression problem and violation of the assumptions of the classical regression model, cointegration analysis is used to examine the long run relationship between the variables. This test is mainly accomplished for identifying the long run relationship among institutional quality, economic freedom and FDI.
Y i, t = α 1 + β 1i x 1 i,t + β 2i x 2 i,t +…. +β Mi x M i,t +e i,t, , t=1,…..T; i=1,….N Here, Y indicates the dependent variable like FDI and X 1 to X m indicates the different independent variables. (See in details Table 2) Another method have used that is known as a Kao for estimating the long run relationship between the variables. Kao have used both DF and ADF to test for co-integration in panel as well as this test similar to the standard approach adopted in the EG-step procedures. Also this test start with the panel regression model as set out in equation 7.
Where Y and X are presumed to be non-stationary and :( see equation 8) where e^ i t = (Y i t -X i t ß^ i t -Z i t ƴ^ ) are the residuals from estimating equation 8. To test the null hypothesis of no co-integration amounts to test H 0 : ρ = 1 in equation 8 against the alternative that Y and X are co-integrated (i, e., H 1 : ρ < 1).

Vector Error Correction Model
The purpose of VECM model is to indicate the speed of adjustment from the short run equilibrium to the long run equilibrium state between the variables from welfare to country International Journal of Accounting and Financial Reporting ISSN 2162-3082 2018 risk. The greater the coefficient of the parameter the higher the speed of adjustment of the model from short runs to long run. Considering the basic equation (1), the VECM model is specified as follows: ∆DFDI= α 0 + α 1 ∑∆Political Stability t-1 + α 2 ∑∆Government effectivesness t-1 + α 3 ∑∆regulatory qualitiest t-1 + α 4 ∑∆Rules of law t-1 +α 5 ∑∆Control of corruption t-1 + α 6 ∑∆Business freedom t-1 +α 7 ∑∆Trade Freedom t-1 + α 8 ∑∆Government Size t-1 + α 9 ∑∆Investment Freedom t-1 + α 10 ∑∆D Property Rights t-1 + α 11 ∑∆D Freedom from coruption t-1 + α 12 ∑∆D Labor Freedomt -1 + α 13 ∑∆Financial Freedom t-1 + α 14 ∑ ∆D Monetary Freedom t-1 + α 15 ∑∆D Democracy t-1 +€ I Where the € I is the error term, ECM (-1) is the error correction term, βi captures the long run impact. The short run effects are captured through the individual coefficients of the differenced terms (α) while the coefficient of the ECM variable contains information about whether the past values of variables affect the current values. The size and statistical significance of the coefficient of the ECM measures the tendency of each variable to return to the equilibrium. A significant coefficient implies that past equilibrium errors play a role in determining the current outcomes.
Considering the demand of the paper when Ω is known, β is efficiently estimated with generalized least squares (GLS).
Instead of assuming the structure of heteroskedasticity, the work may estimate the structure of heteroskedasticity from OLS. First, estimate ̂ from OLS and, second, use ̂ instead of Ω.
International Journal of Accounting and Financial Reporting ISSN 2162-3082 2018 After GLS and FGLS the paper has also tested OLS. A standard panel OLS estimator for the coefficient ß i given by: Where i = cross-section data and N is the number of cross-section t = time series data and T is the number of time series data ß^i OLS = a standard panel OLS estimator The most commonly used models in panel data analysis are fixed effects (FE) and random effects (RE) regressors in linear regression using ordinary least squares (OLS).
Here in this paper the fixed effects model is used binary variables. So the equation for the fixed effects model becomes: Where, Y it = is the dependent variable (DV) is FDI where i = entity and t = time.

Their estimates are labeled b 1, b 2…. b k. ISSN 2162-3082 2018 Using this notation, the fundamental Poisson regression model for an observation i is written as

Where, That is, for a given set of values of the regressor variables, the outcome follows the Poisson distribution.
In the Prais-Winsten the equation is Where Y t is the time series of interest at time, β is a vector of coefficients, X t is a matrix of explanatory variables and ε t error terms. The error terms can be serially correlated over time ε t = pε t-1 + е t , | p| < 1 and e t is a white noise.
In the Generalized Method of Moments estimator based on these population moments conditions is the value of θ that minimizes.
Where W n is a non-negative definite matrix that usually depends on the data but converges to a constant positive definite matrix as n ∞.
The GEE approach estimates β by solving the estimating equations (Liang and Zeger), and (Prentice): Where D i = D i (β) = ∂ I (β)/∂β′, and V i is the working covariance matrix of Y i . V i can be expressed in terms of a correlation matrix R (α): , specified as functions of the means μ it, α is some unknown parameter.

Data Sources
This article has employed panel data for 79 countries over the period from 1998 to 2014 among different developing countries (See in Table 1). Here the FDI which is noted as an dependent variable is measured in current U.S. dollars divided by the host country"s total population as the dependent variable, and data come from UNCTAD. Data on FDI are provided by several sources, such as Balance of Payments Statistics Yearbook and e -1 t International Journal of Accounting and Financial Reporting ISSN 2162-3082 2018 International Finance Statistics by the International Monetary Fund (IMF), European Union Direct Investment Yearbook by EUROSTAT, World Investment Report by UNCTAD, World Development Indicators by the World Bank, and International Direct Investment Statistics Yearbook by OECD. Only the UNCTAD, OECD, and EUROSTAT offer a sectoral breakdown of FDI flows and stocks. The drawback of using the data from OECD and EUROSTAT is only cover a very limited number of world countries and thus the total direct investment received by any given country cannot be completely assessed. Moreover, the paper is more interested in FDI inflows than FDI stocks because policy recommendations are usually formulated to boost FDI inflows rather than to accumulate FDI stocks for a given period. However, only UNCTAD provides a break down into two different categories: FDI figures for developed and for developing countries that really serve our purpose. Because of making contemplative judgment FDI related data are accumulated from the UNCTAD. For the independent variable like institutional quality that is including the six different factors, voice and accountability, political stability and violence, government effectiveness, regulation quality, rules of law and control of corruption. Data are aggregating from the worldwide governance indicators. Here the voice and accountability is not considered for our purpose. Data collection method and research methodology all the things can be access in that particular website: www.govindicators.org.
Here in this study the paper has applied the Index of Economic Freedom provided by Heritage Foundation, for measuring economic freedom that is another independent variable which is included 50 independent variables fall into 10 categories of economic freedom. Each country receives its overall economic freedom score based on the simple average of the 10 individual factor score. Each factor has a unique scale that runs from 1 to 5, where a score of 1 indicates an economic environment that are most conducive to economic freedom and a score of 5 indicates the opposite.   ISSN 2162-3082 2018 The Table 5 highlights the pedroni cointegration test. From the no deterministic trends there are 7 different and separate outcomes. Out of 7 outcomes, 3 outcomes interpret that the paper has accepted the null hypothesis (H 0 = No co-integration), because the p value is > 5. On the other hand 4 outcomes illustrates that reject the null hypothesis and accept the alternative hypothesis. Therefore it is to be noted that base on the no deterministic trend elucidates that the variables are cointegrate. On the other hand from the deterministic intercept and trends way out of 7 outcomes 5 outcomes interpret that accept the null hypothesis (H 0 = No Co-integration), because the p value is > 5. On the other hand 2 outcomes illustrates that reject the null hypothesis, it means that accept the alternative hypothesis. Therefore it is to be noted that base on the deterministic intercept and trend elucidate that the variables are not cointegrate. From the no deterministic intercept and trends out of 7 outcomes, 4 outcomes interpret that reject the null hypothesis (H 0 = No integration), because the p value is < 5. On the other hand 3 outcomes illustrates that accept the null hypothesis, it means that reject the alternative hypothesis Therefore it is to be noted that base on the no deterministic intercept and trend method elucidates that the variables are cointegrated. It means that two different methods out of three of the Pedroni Residual Cointegration Test the variables are cointegrate. Another lucid method (Kao Residual Cointegration) is used to estimates whether the variables are cointegrate. From the table: 6 it exhibits that the p value is less than 5%, means it reject the null hypothesis (H 0= No co-integration).  Table 7 illustrates that C(1) means speed of adjustment towards long run equilibrium but it must me significant and the sign must be negative. There is long run causality from the variables such as FDI, political stability, government effectiveness, regulatory qualities, rules of law, control of corruption, business freedom, trade freedom, government size, investment freedom, property rights, freedom from corruption, labor freedom, financial freedom, fiscal freedom, monetary freedom and democracy.

In the case of business freedom, trade freedom, government size, investment freedom, property rights, freedom from corruption, labor freedom, financial freedom, fiscal freedom and monetary freedom the coefficient implies that a one standard deviation improvement in business freedom, trade freedom, government size, investment freedom, property rights, freedom from corruption, labor freedom, financial freedom, fiscal freedom and monetary freedom increases FDI by 35. 8%, 19.2%, 29.5%, 29.4%, 25.3%,30.7%, 27.3%,19.2%,29.3% and 21.0% respectively which is higher from than in the case of OLS and Random Effect Model.
The fourth column presented the Poisson Regression estimates. Under the institutional quality all the variables are positive and significant influence on FDI. The coefficient implies that a one standard deviation improvement in political stability, government effectiveness, regulatory quality, rules of law and control of corruption increased FDI by 15.9 %, 34.8%, 29.5%, 20.8% and 42.4%. In the case of business freedom, trade freedom, government size, financial freedom and monetary freedom the coefficient implies that a one standard deviation improvement in business freedom, trade freedom, government size, financial freedom and monetary freedom increases FDI by 36.3%, 24.7%, 31.3%, 25.1% and 27.3% respectively which is slightly higher than in the case of OLS, Random Effect Model and Fixed Effect Model. On the other hand the other variables like investment freedom, property rights, freedom from corruption, labor freedom and fiscal freedom the coefficient implies that a one standard deviation improvement in investment freedom, property rights, freedom from corruption, labor freedom and fiscal freedom increases FDI by 15.7%, 19.4%, 29.5%, 23.6% and 27.3% respectively and which is slightly lower from the fixed effect model.   ISSN 2162-3082 2018 From the fifth column according to the Prais-Winsten estimates, here all the variables under the institutional qualities are positive and significant. Here the coefficient of the political stability and rules of law are slightly higher from the poisson regression estimates. On the other hand the coefficient of government effectiveness, regulatory qualities and control of corruption implies that a one standard deviation improvement in government effectiveness, regulatory qualities and control of corruption increases FDI by 21.9%, 24.4% and 36.6% respectively which are slightly lower from the poisson regression estimates. In the case of business freedom, labor Freedom, and monetary freedom the coefficient implies that a one standard deviation improvement in business freedom, labor freedom and monetary freedom increases FDI by 34.9%, 21.9% and 21.6% respectively which is lower from the poisson regression estimates. On the other hand the other variables under the economic freedom like trade freedom, government sizes, investment freedom, property rights, freedom from corruption, financial freedom and fiscal freedom the coefficient implies that a one standard deviation improvement in trade freedom, government sizes, investment freedom, property rights, freedom from corruption, financial freedom and fiscal freedom increases FDI by 28.3%, 33.7%, 21.5%, 23.8%, 30.5%, 32.6% and 28.4% respectively which is slightly lower from the poisson regression estimates.
From the sixth column of the table concentrates on the GMM estimates, here noted that all the variables under the institutional qualities are positive and significant. The coefficient values of the political stability, government effectiveness, regulatory qualities, rules of law and control of corruption implies that a one standard deviation improvement in political stability, government effectiveness, regulatory qualities, rules of law and control of corruption increases FDI by 24.2%, 36.2%, 28.5%, 26.3% and 57.6% respectively. On the other hand the economic freedoms are also explored to be positive and significant. In the case of business freedom, trade freedom, government Size, investment freedom, property rights, freedom from corruption, labor freedom, financial freedom, fiscal freedom and monetary freedom the coefficient implies that a one standard deviation improvement in business freedom, trade freedom, government size, investment freedom, property rights, freedom from corruption, labor freedom, financial freedom, fiscal freedom and monetary freedom increases FDI by 29.5%, 31.6%, 39.8%, 31.4%, 29.6%, 27.2%, 28.4%, 26.3%, 31.7% and 29.4% respectively.
From the seven column of the table according to the GEE estimates, all the variables under the institutional quality and economic freedom are also explored to be positive and significant. The coefficient values of the political stability, government effectiveness, regulatory qualities, rules of law and control of corruption implies that a one standard deviation improvement in political stability, government effectiveness, regulatory qualities, rules of law and control of corruption increases FDI by 31.7%, 31.6%, 32.4%, 28.5% and 58.4 % respectively. In the case of business freedom, trade freedom, government size, investment freedom, property rights, freedom from corruption, labor freedom, financial freedom, fiscal freedom and monetary freedom the coefficient implies that a one standard deviation improvement in business freedom, trade freedom, government Size, investment freedom, property rights, freedom from corruption, labor freedom, financial freedom, fiscal freedom and monetary freedom increases FDI by 31.8%, 38.2%, 41.7%, 39.2%, 31.7%, 46.2%, 32.5%, 35.2%, 41.4% and 31.6% respectively.
