The present article considers an endogenous growth model in which the service output is used as intermediate good in commodity sector, tax is imposed on manufacturing product and the revenue earned is invested to create human capital. It is shown that there exists a unique, saddle path stable steady-state growth rate of human capital accumulation and a unique growth-maximizing tax rate. The optimal tax rate for the command economy is compared with growth-maximizing tax rate in competitive economy. A numerical analysis shows that the command economy will have a higher growth rate than the competitive economy. An extension of the model where households privately spend for accumulation of human capital yields the same growth rate as that of the command economy of the previous model.

The main purpose of this study is to test if the use of social networking sites (SNSs) results in any perceived social capital for the users. Putnam’s classification of social capital into bridging and bonding social capital is used for the study. The first objective of the study was to study the demographic and behavioral profile of LinkedIn users. The second objective was to test the model describing the relationship between the constructs intensity of LinkedIn usage and the two types of social capital. A structured questionnaire that included standard scales for measuring the constructs was shared on various social media platforms. The model was analyzed using PLS-SEM in R software. The results confirmed all the three hypothesized relationships and also validated the overall model. This study contributes to the validation as well as extension of social capital theory in SNS. Further, the results throw light on the new applications of SNS by the industry.

The paper analyses the optimal tax policy in an endogenous growth model in a command economy, where the commodity output is produced with only physical capital, and skilled labour is the only input in producing the service good. In the benchmark model, per capita government expenditure is used to create human capital. Two cases are considered regarding taxation: in the first, tax is imposed on both commodity and service sectors, while in the second only the service sector is taxed. In each case the model derives the optimal tax rate and steady-state growth paths. In the first regime where both sectors are taxed we find the optimal tax rate on the service sector to be zero, but on commodity output it is positive. However, in the second regime there is also a unique optimal tax rate on the service sector to finance human capital accumulation. Comparing the growth rates in both cases we also observe that the imposition of tax on only the service sector instead of on both sectors yields a higher rate of growth if the population growth rate along with the marginal productivity of human capital is sufficiently high. We also show that when the service sector is taxed it may grow at a higher rate than the manufacturing sector. An extension of the benchmark model in which government spends tax revenue on accumulation of human capital as well as physical capital confirms that the optimal service tax rate is zero, but the optimal commodity tax rate is positive when both sectors are taxed.
