The present study attempts to investigate whether shadow economy and the tourism sector are related. In the European countries, Schneider reported that 20 to 25 per cent of the shadow economy is represented in the tourism-related industries – wholesale and retail, automotive and motorcycle sales and maintenance; transportation, storage and communications; and hotels and restaurants. For the tourism sector, the services given by operators (unregistered and/or underreporting) operate in the shadow economy will ultimately wiped off the map of high quality tourist destinations and destroyed the development of the tourism industry itself. This study examines the short-run and long-run relationships between international tourism receipts and shadow economy for 149 countries over the period 1995-2008. We use a generalized one-step error-correction model (ECM) in combination with a system Generalized Method of Moments (GMM) to explore the long-run relationship between these two variables. Our results suggest that tourism receipts and shadow economy are cointegrated. This implies that shadow economy and the tourism industry worldwide are related in the long-run. The long-run elasticities indicate a negative impact of the shadow economy on the tourism sector suggesting that increase in shadow economy activities will adversely affecting the tourism industry.

This study examines the impact of foreign aid on the institutional quality (IQ) of the OIC countries. Using the data of OIC countries for the three-year average period from 1991 to 2016, the system GMM finds that aid in general deteriorates the IQ for the aid recipient countries. However, quantile regression suggests that the negative impact of foreign aid on institutional quality (IQ) is relatively greater in the countries where the existing quality of institution is poor. The findings of the study suggest that improving the existing capacity is essential for reaping the optimum benefit of foreign aid on institutional development.

The present paper seeks to assess the implications of increasing financial sector size on income inequality in eight Asian countries - Hong Kong, India, Indonesia, Japan, Malaysia, the Philippines, Singapore, and South Korea. Adopting a panel data approach, it document a non-linear relation between income inequality and financial sector size in these countries. More precisely, the increasing financial sector size is favourable to equal income distribution only up until a size threshold, beyond which further expansion of the financial sector can worsen income distribution. The analysis further highlights the income-equalizing effect of economic growth and infrastructure development and the income un-equalizing effect of trade and government expenditures. These results are robust to alternative model specifications and to exclusion of a country at a time from the sample.

Countries with high levels of human development should be able to reduce the impact of natural disasters in terms of the total numbers of people killed and affected, and damage. In this study we investigate the impact of human development indicators such as income per capita and human capital (education level) on natural disaster fatalities (total deaths, total affected and total economic losses) in 79 selected countries. Using dynamic panel data analysis, we found that the level of economic development plays an important role in mitigating the impact of natural disasters such as droughts, earthquakes, extreme temperatures, floods, storms, volcanoes, landslides and wildfires. Other factors that are found to determine the number of natural disaster fatalities include population, population density, unemployment, investment, government consumption, openness, education and corruption. Using the dynamic panel data model, we found that education, investment, government consumption and openness display an inverse relationship, while population and population density have a direct positive relationship.

The present paper addresses the question whether the less developed states, namely; Kedah, Kelantan, Pahang, Perlis, Sabah, Sarawak and Terengganu are converging with the richer state of Selangor, using unit root test and cointegration approach to test for income convergence for the period 1970-2013. We tested convergence on per capita real GDP for the states involved and the results suggest that the less developed states have been converging to the state of Selangor for the period under study. We also identify two convergence clubs among the states. In this respect, the state government has an important role to play in enhancing growth by continuously providing stable economic environment for investment and other productive economic activities. Without the Five-Year Malaysia Plans, this convergence phenomenon could not have been achieved in Malaysia. To ensure further convergence can take place at a faster rate in the future, government efforts and policies to foster narrowing states' income disparity has to be enforced further.

The present paper analyses the relations between food and oil prices for Malaysia using a nonlinear autoregressive distributed lags (NARDL) model. The bounds test of the NARDL specification suggests the presence of cointegration among the variables, which include the food price, oil price and real GDP. The estimated NARDL model affirms the presence of asymmetries in the food price behavior. Namely, in the long run, we find a significant relation between oil price increases and food price. Meanwhile, the long run relation between oil price reduction and the food price is absent. Furthermore, in the short run, only changes in the positive oil price exert significant influences on the food price inflation. With the absence of significant influence of oil price reduction on the food price both in the long run and in the short run, the role of market power in shaping the behavior of Malaysia’s food price is likely to be significant.

The present paper examines the mitigating effect of social capital on the environmental Kuznets curve (EKC) for CO2 emissions using a panel data of 69 developed and developing countries. Adopting generalised method of moments (GMM) estimators, the paper finds evidence substantiating the presence of EKC. Moreover, the evidence suggests that the pollution costs of economic development tend to be lower in countries with higher social capital reservoir. Surprisingly, there is also evidence to indicate that the income threshold point beyond which CO2 emissions decline is higher in countries with higher social capital. These results are robust to addition of alternative controlled variables in the EKC specification. Thus, in addition to policy focus on investments in environmentally friendly technology and on the use of renewable energy, investments in social capital can also mitigate the pollution effects of economic progress.
