Abstract This study examines the relationship between the life insurance and economic growth in India. The total life insurance premium (TLIP), and total life insurance investment (TLII), are used as proxy for life insurance and Gross Domestic Product (GDP) is used for the economic growth. The data has been compiled from the Handbook on Indian Insurance Statistics, IRDA annual reports and economic survey for the time period 1990-91 to 2010-11. The Ordinary Least Square regression model has been used for data analysis. The Breusch-Godfrey Serial Correlation LM, Heteroskedasticity: Breusch-Pagan-Godfey, Jarque- Bera, Collinearity Diagnoses tests have also applied to check robustness of the OLS regression model. The Major findings of the study are that life insurance significantly influences the economic growth in India. JEL Classification: G22, G23, E01, C01. Keywords: India, Life Insurance Premium, Investment, GDP, and OLS. 1. Introduction A life insurer at the event of un-timely policyholder s death provides the fast recovery of family members against financial crisis in return of a fee which is called premium (Spencer and Heppen, 1969; Ranade and Ahuja, 1999; Fabozzi, 2006; Pandey and
414 Anju Verma & Renu Bala Manocha, 2011). Apart from providing protection an insurer can affect the economic growth in the form of financial intermediary (Curak, et al., 2009). The rapid growth of life insurance premium not only increases the role of a life insurer as risk provider, but also increases it importance as institutional investor (Lee, et al., 2013). The function of financial intermediation of life insurance is relatively more prominent than that of nonlife insurance (Chang, et al, 2013). The life insurance sector is the largest long-term investor in Indian economy (Kallinath, 2003; Rangarajan, 2006). There is a good theoretical justification that insurance sector influences economic growth and vice versa (Haiss and Sumegi, 2008 p.425). As far as, Indian economy is concerned, the contribution of insurance in GDP has increased (Parekh & Banerjee, 2010). Thus, the present study is an effort to investigate the statistical significance of the life insurance in economic growth of India. The rest of the study is organized in following sections: section 2 describes the review of literature. Section 3 presents the need of study, and section 4 explains the objective of the study. Section 5 describes the methodology. Section 6 covers the empirical results and interpretation. Section 7 concludes the study. 2. Review of Literature Ward and Zurbruegg (2000) examined the relationship between GDP and insurance growth. With, the data set of 9-OECD countries, and these countries were Australia, Austria, Canada, France, Italy, Japan, Switzerland, UK and US. It was found that insurance premium was Granger Cause of GDP in some countries but for some countries it was not true. Muthusamy and Meera (2008) demonstrated the important role of Indian life insurance sector in economic development. Parekh and Banerjee (2010) reviewed that in India insurance sector has had significant impact on the economic development. This sector is gradually increasing and its contribution in GDP is also increasing. Han, et al. (2010) investigated the relationship between insurance development and economic growth, using the data set of 77 countries. It was found that insurance density impact plays very important role in developing countries rather than developed ones. Ching, et al. (2011) analyzed the existence of causal relationship between total assets of general insurance sector and GDP in Malaysia. It was found that the long-run relationship exists between the total assets of general insurance and GDP. And in the short-run causal relationship was absent (in both directions). Michael, Ojo (2012) examined the short and long run relationships between GDP and insurance sector growth of Nigeria. It was found that insurance sector growth positively and significantly affect the GDP. The long run relationship between the insurance growth and GDP was also confirmed. Hou, et al. (2012) investigated the impact of financial institutions and GDP in 12 Euro-countries. Two major conclusions were found: first it was from cross-country evidences that life insurance penetration and banking development do not have any significant impact on GDP. Secondly, the life insurance and banking development are significant predictors of GDP. Horng, et al. (2012) examined the relationship among the insurance demand, financial development and

It was found that there was an equilibrium relationship between the insurance demand, financial development and GDP. The study found that in short run, GDP was Granger cause of insurance demand and financial development was Granger cause of GDP. It was finally concluded that financial development promotes GDP and GDP further promotes the insurance demand. Lee, et al. (2013) analyzed the long term and short term relationship between the GDP and real life insurance premium of 41 countries. It was found that in the long term one unit increment in the real life premium will raise the GDP by 0.06 units. The life insurance markets development determines the economic growth in the long-run and in the short term, bidirectional causalities were found between them. Chang, et al. (2013) investigated the causal relationship between the insurance activities and GDP, using a data set of 10 OECD countries. It was found that there was a significant and positive relationship between the overall insurance growth and economic growth for 5 countries out of 10 OECD countries. 3. Need of the Study The role of insurance sector in economic growth has hardly been investigated empirically in literature as compared to banking sector and stock markets (Arena, 2006; Chang, et al., 2013). The worldwide growth of insurance and its influence on the government action is a clear indication of its importance in Indian economy too (Mohananasundari and Balanagagurunathan, 2011). This fact prompts us to examine this issue empirically in India. 4. Objective of the Study To examine the significant relationship between the life insurance and GDP in India. 5. Methodology Hypothesis: There is no significant relationship between the life insurance and GDP in India. The data: This study is empirical by nature as is based on secondary data. That has been compiled from the Handbook on Indian Insurance Statistics, IRDA annual reports and economic survey. Variables Definition: the variable GDP as proxy for economic growth is taken as dependent variable. The independent variables of the study are total life insurance premium (TLIP), total life insurance investment (TLII), covering the time period from 1990-91 to 2010-11. Model: the OLS regression model has been taken as statistical tool for data analysis (Browne and Kim, 1993; Michael, 2012). In order to check the efficiency and unbiasedness of the estimated coefficients of the OLS regression model the following tests has been applied: The Breusch-Godfrey Serial Correlation LM test, Heteroskedasticity test: Breusch-Pagan-Godfey, Jarque-Bera, Collinearity Diagnoses
416 Anju Verma & Renu Bala tests. All the variables (TLIP, TLII and GDP) of the study are transformed by taking first difference for reducing the problem of serial correlation, heteroscedasticity and multicollinarity. 6.

A significant impact of life insurance on economic growth is observed in India. It is found that if the life insurance investment increases by one unit holding the other things constant then on the average GDP increases by (0.57), and it is statistically significant at 5% level. The life insurance premium increases by one unit then on the average GDP increases by (3.43) holding other things constant. It influences significantly to the GDP at 1% level.
The Relationship between Life Insurance and Economic Growth: Evidence 417 Tables 1-5 present the robustness of the OLS regression model. The R-square and adjusted R-square of the model are (0.86 and 0.85), respectively more than (0.60). The F-statistic significance is a good indicator of the overall significance of the model. The Durbin Watson is (1.86), which is near about (2), it makes clear that the residuals are not serially correlated. Again we are selecting the JB (Jarque-Bera) test, which is based on OLS residuals. To compute the Jarque-Bera test the Skewness and Kurtosis, and the OLS residuals has to compute first. It has the following statistic: JB n H : Residuals are normally distributed, which is tested with associated P-value. If the P-value is reasonably high then a researcher does not reject the normality assumption (Gujarati, 1995). The p-value is (0.95) the null hypothesis has accepted that residuals are normally distributed. 7 6 5 4 3 2 1 0-100000 -50000 0 50000 100000 Series: Residuals Sample 2 21 Observations 20 Mean -7.64e-12 Median 3374.814 Maximum 80569.49 Minimum -75300.47 Std.

418 Anju Verma & Renu Bala Table 3 exhibits that the null hypothesis of homoscedasticity has been accepted. The Breusch-Pagan-Godfrey test makes clear that the residuals of the model are free from heteroscedasticity. The coefficient estimates of the OLS regression model are efficient.

Table-4 exhibits that Variance Inflation Factor of both variables as follows: (3.1 and 3.1) it means the problem of highly co linearity does not exist in among the variables. The, tolerance is (0.32 and 0.32). Table 5: Collinearity Diagnostics.

In summing up it is concluded that all these above mentioned tests confirmed that the
The Relationship between Life Insurance and Economic Growth: Evidence 419 estimated coefficients of the OLS regression model are the best, linear, efficient and unbiased. Conclusions These results provide empirical evidence that life insurance has both positive as well as significant impact on the economic growth in India. The null hypothesis has been rejected. In current scenario, India has huge insurable population, is good hope for life insurance sector. Scope for further studies: Further research work need to be done in the same direction by applying different time period and different methodologies such as simultaneous equation model, Vector auto-regression, Granger causality and cointegration. The results may be more interesting than current study. References [1] Arena, M. (2006). Does Insurance Market Activity Promote Economic Growth?
