Impact of services trade on economic growth and current account balance: Evidence from India

This paper aims to study the impact of services trade on India’s economic growth and current account balance during the post-reform period. Earlier studies on this subject have mostly looked at the goods sector. Indian studies which analysed services-led growth from a balance of payments perspective suffered from a bias of having focused only on call-centre exports. In such a context, this study brings in a novel approach by using the Balance of Payments Constrained Growth model and autoregressive distributed lag cointegration to estimate the balance of payments equilibrium growth rate for India’s service sector. The key service sub-sectors are also identified using input–output tables and the TIVA database. This study finds that India’s service sector is growing at a rate almost equal to its balance of payments equilibrium growth rate under the assumption of constant relative prices in international trade, and at a rate lower than the equilibrium growth rate when this assumption is relaxed. Among the major services in India’s export basket, construction, transport and business services are found to exhibit strong backward linkages. Foreign value-added content in India’s services exports is found to be highest in the case of business services, transport services and telecommunications.     

GDP growth determinants and foreign direct investment causality: the case of Iran

Given the economic conditions in Iran and the need to accelerate its economic growth, there is a rising interest in examining the variables that fuel its GDP growth. The scant literature on economic growth in Iran is composed of only a few scholarly studies that investigate this nation's GDP growth. However, none of these studies has examined the causality between GDP growth and its determining elements. The purpose of this study is: (1) to determine the economic variables that contribute to Iran's GDP per capita growth over time, and (2) to examine the causality between foreign direct investment and the relevant variables that are included in the model. To achieve these goals the study uses a model that is based on the postulates of de Mello. The results indicate that: (1) the major determinants of GDP per capita growth in Iran are value added growth and domestic investment growth; (2) there is no causal relationship between foreign direct investment growth and GDP per capita growth in Iran in either direction; and (3) there is no causal relationship between foreign direct investment growth and value added growth in Iran in either direction.     

The use of sampling methods in advertising research: a gap between theory and practice

In this research note, we reflect critically on the use of sampling techniques in advertising research. Our review of 1028 studies published between 2008 and 2016 in the four leading advertising journals shows that while current academic literature advocates probability sampling procedures, their actual usage is quite scarce. Most studies either lack information on the sampling method used, or engage in non-probability sampling without making adjustments to compensate for unequal selection probabilities, non-coverage, and sampling fluctuations. Based on our results, we call on researchers to revisit the fundamental aspects of sampling to increase their research results’ rigour and relevance.
