Human capital,investment and growth: Some results from an endogenous growth model

Recent theoretical literature on the sources of economic growth has emphasized the role of human capital as an internal contributing force in the growth process. Empirical results reported in this paper provide support for this theoretical proposition. Cross-country data from 32 developing countries indicate that human capital (as alternatively measured by the primary school enrollment rate or the adult literacy rate) exerts a significant positive impact upon output growth.     

Variable labour supply, specialisation-based external economies, and capital inflow

This paper examines the impact of exogenous capital inflow on prices, production, labour supply, and welfare in the presence of specialisation-based externalities. The paper utilises a simple model of an economy that produces one-final good by means of capital, labour, and a large number of varieties of an intermediate good. The intermediate good is produced by means of capital and labour. The supply of capital is exogenous but the supply of labour is endogenous. The presence of internal economies of scale in the intermediate good industry gives rise to specialisation-based external economies in the production of the final good. Perfect competition prevails in the final good industry whereas the intermediate good industry operates under Chamberlinian monopolistic competition. It is shown that exogenous capital inflow decreases labour supply and increases welfare only if the elasticity of substitution between leisure and the final good is equal to or less than unity. The paper also shows that, if trade opens up between two otherwise similar economies, a capital rich country would be a net importer of varieties of the intermediate good.     

Foreign direct investment and trade: The case of Vietnam

By making use of a gravity model, this paper examines the impact of FDI on exports, imports and net export of Vietnam. The empirical analysis presented in this paper is based on a recently released panel dataset involving Vietnam's 19 major trading partners for the period 1990-2007. The paper also considers the impact of FDI on trade during three sub-periods: the pre-Asian financial crisis, the post-Asian financial crisis and during the Asian financial crisis period. The empirical analysis reveals that a complementary relationship exists between FDI and exports and FDI and imports. While the impact of FDI on net-exports is insignificant during the full sample period, a significant positive relationship exists between net-exports and FDI in the post-Asian financial crisis period.     

Trade liberalisation,market competition and wage inequality in China's manufacturing sector

Economic reforms of the late 1980s have contributed to rapid economic growth in China. While the overall standard of living has improved, economic growth has also resulted in an increase in income inequality. Rising income inequality can increase social tensions that can impede further economic growth. By making use of firm level panel data, this paper focuses on the impact of increased market competition and trade liberalisation on skilled–unskilled wage inequality in China's manufacturing sector. A theoretical model is used to argue that trade liberalisation and market competition can affect skilled–unskilled wage inequality. Based on this result, an econometric model is specified. The empirical analysis presented in this paper shows that increased trade liberalisation has contributed to an increase in skilled–unskilled wage inequality in China's manufacturing sector. However, increase in market competition has the opposite effect.     

International Transmission of Government Spending,Monopolistic Competition and North-South Trade

This paper utilises a North–South general equilibrium model where South exports an intermediate good to North in exchange for differentiated goods. The model is used to examine international transmission of government spending and its welfare implications. It is shown that an increase in government spending in North (South) can increase (decrease) the number of differentiated goods produced, thereby decreasing (increasing) the degree of monopoly power in North. Furthermore an increase in government spending in South can decrease the welfare North, but the impact of an increase in government spending in North the welfare of South cannot be unambiguously determined.

Labour mobility and wage inequality in the presence of endogenous foreign investment

This paper examines the impact of labour mobility and increased competition on skilled–unskilled wage inequality and foreign investment. Unlike the existing literature this paper considers a model where foreign investment is endogenously determined. The paper shows that in the shortrun, inflow of either skilled or unskilled labour has no effect on wage inequality but increased competition increases wage inequality. Inflow of either type of labour increases foreign investment but the impact of increased competition on foreign investment cannot be unambiguously determined. Inflow of skilled labour increases wage inequality in the longrun and its effect on foreign investment is positive. Increased competition in the longrun increases wage inequality, foreign investment and welfare.     

Factors affecting consumers’ intention towards purchasing halal food in South Africa: a structural equation modelling

This research study highlighted the factors that influence the intention of consumers to buy halal food products. In this study, the researchers have chosen to address the gap in the literature pertaining to non-South African consumers’ purchase intention. Non-South Africans are foreign people who reside in South Africa including immigrants, workers, and students. Through utilising the theory of planned behaviour, this study aims to determine the attitudes, subjective norms, perceived behaviour control, and awareness of non-South African towards purchasing halal food products. This also attempts to identify the strongest factor that influences the purchasing intention of halal food by non-South African consumers. The sample of the study consisted of 230 non-South African consumers in Cape Town. Data were collected through self-administered questionnaires. Structural equation modelling (SEM) was used to identify the structural relationships among the constructs identified and to test the study hypotheses. The findings of this study indicate that there is a significant relationship between awareness and buying behaviour. Interestingly it found that only the attitude dimension of TPB had a significant relationship with purchase intention, whereas subjective norms and perceived behavioural control did not show a significant relationship with the consumer intention variable.     

The Pricing Kernel Puzzle: A Real Phenomenon or a Statistical Artifact?

A large literature finds evidence that the pricing kernels estimated from option prices and historical returns are not monotonically decreasing in market returns. We show that the inevitable coalescence of contingencies, especially in the left‐tail, associated with estimating a distribution function may give rise to a nonmonotonic empirical pricing kernel even if the actual pricing kernel is monotonic. Hence, the observed nonmonotonicity of pricing kernels may be a statistical artifact rather than a real phenomenon. We argue that empirical work should explicitly correct for this effect by widening the option pricing bounds associated with monotonic pricing kernels.     

Personality and balanced psychological contracts: The mediating roles of epistemic curiosity and rule‐following behavior

This study extends prior research on the relationships between personality constructs and types of psychological contracts by exploring how the Big Five traits predict balanced psychological contracts. Further, we determine whether epistemic curiosity and rule‐following behavior are key mediators of the proposed relationships. We tested our proposed hypotheses using three‐wave time‐lagged data from 469 respondents. The results indicated that openness to experience was positively associated and both conscientiousness and neuroticism were negatively associated with balanced contracts. Extraversion and agreeableness were not associated with balanced contracts. We also established the mediating role of epistemic curiosity in the relationships between personality traits and balanced contracts, but there was no support for the mediating role of rule‐following behavior in the present study. These findings have important implications for managers and organizations in terms of selecting the right person for a job (person‐job fit) and ensuring employee retention (person‐organization fit), hence having a bottom‐line effect on firm performance. Future research directions are also discussed.     

Capital account flows,consumption ratios and the middle‐income trap

The existing literature suggests that it is important to understand the factors that may slow the transition of an economy from middle to high income. Many factors have been suggested as promoting or retarding economic growth, but little attention has been paid to the roles of the capital account and consumption ratio. Using panel regressions involving 48 countries over the 1950–2013 period as well as employing extreme bounds analysis, we find that foreign investment outflows are associated with a mature economy and that there is an optimal consumption ratio that must be surpassed to break out of middle‐income status. These findings are robust to an extreme bounds analysis incorporating a wide range of variables potentially related to growth performance.
