Testing for the random walk hypothesis in the case of visitor arrivals: evidence from Indian tourism

Testing for the random walk hypothesis, which asserts that a series is a non-stationary process or a unit root process, in the case of visitor arrivals has important implications for policy. If, for instance, visitor arrivals are characterized by a unit root, then it implies that shocks to visitor arrivals are permanent. However, if visitor arrivals are without a unit root, this implies that shocks to visitor arrivals are temporary. This study provides evidence on the random walk hypothesis for visitor arrivals to India using the recently developed Im et al. (2003) and Maddala and Wu (1999) panel unit root tests. Both tests allow one to reject the random walk hypothesis, implying that shocks to visitor arrivals to India from the 10 major source markets have a temporary effect on visitor arrivals.

The dynamics of industrial concentration in Australian manufacturing

Abstract A dynamic model of concentration is developed, with incomplete and industry-specific adjustment to deviations of concentration from its steady state. Cross-sectional analysis is carried out against a sample of 102 Australian manufacturing industries at the Australian Standard Industrial Classification (ASIC) four-digit level over the period 1977/78–1984/85. The estimated adjustment is faster than found in studies of the more mature industrial economies and this adjustment is found to significantly increase with reductions in tariff protection. There is also empirical support for John Suttons argument that the relationship between concentration and market size depends on whether set-up costs are exogenous.

Industrial concentration and competition in Malaysian manufacturing

Industrial concentration is the most widely studied area among various elements of market structure in the industrial organization literature. This paper is a first attempt to analyse the determinants of changes in industry concentration over time in the case of Malaysia. Using a partial adjustment model, a cross-sectional analysis is carried out against a sample of manufacturing industries between 1986 and 1996. Domestic factors in influencing competition e.g. capital intensity, advertising intensity and market size are found to be significant in most cases to explain the level of concentration. Considering variable rate of adjustment of concentration, an increase in labour productivity of large firms and high entry rates are found to be significant for faster adjustment towards equilibrium level. Compared with other developed countries, the annual rate of structural adjustment is found to be slow in the case of Malaysian manufacturing.

The Determinants of Judicial Prestige and Influence: Some Empirical Evidence from the High Court of Australia

This paper uses judicial citation practice to investigate the determinants of judicial influence in the High Court of Australia. First, we construct measures of influence based on the number of times a judge is cited by name in a sample of High Court decisions. The raw citation counts are adjusted to exclude self‐citations, depreciation of legal capital, and variations in terms of period in office. Second, our measures of influence are regressed on a series of explanatory variables including age on appointment, appointing government, prior experience, and whether the judge served as chief justice, for each of the 35 retired judges of the High Court. They suggest that younger appointees with prior judicial experience exert more influence per year on the bench. Our results also suggest that conservative appointees exert more influence than Labor appointees and judges who have served as chief justice exert more influence than puisne judges.

Aging and Productivity Among Judges: Some Empirical Evidence from the High Court of Australia

A number of studies has shown that productivity declines with age in a wide range of activities. Based on United States experience, it has been argued that one profession that might be an exception to this phenomenon is the judiciary. This study explores the relationship between aging and productivity for a sample of retired judges of the High Court of Australia. The High Court provides a useful test for the hypothesis that older judges are more productive because, in contrast to the United States, most, if not all, judges write their own judgments. Thus, ghostwriting does not cloud the issue of judicial productivity. The findings support the life-cycle hypothesis, which suggests the age-citation profile should increase, reach a peak and then decline as judges get closer to retirement. Thus, the results are consistent with the view that the productivity of judges over their working lives follows a similar pattern to other professions such as academia.

Natural gas, trade and sustainable growth: empirical evidence from the top gas consumers of the developing world

ABSTRACT Natural gas is the key non-renewable source of energy for a low-carbon economy. The research applies heterogeneous panel techniques to investigate the impact of natural gas consumption on economic growth across a panel of top 15 natural gas consumers of the developing world. We establish long-run dynamics with cross-sectional dependence and heterogeneity across the sample countries. The long-run output elasticities suggest that the natural gas consumption and trade variables have significant positive effect on the output in a panel of developing economies. Further, we establish feedback relationship among gas consumption, output and trade in the short-run. Given the significance of natural gas as the low-emission source of energy, we suggest governments and policy advisers of these major natural gas consumers to focus on developing pipeline infrastructure for adequate supply, reforming natural gas sector with a competitive price structure to combat excess demand in individual natural gas market. With trade integration, majority of these countries need to incorporate these initiatives to improve the technologies such as combined cycle power plant technology and value-added chemical production technology to achieve sustainable economic growth.

THE IMPACT OF GLOBALIZATION ON CO2 EMISSIONS IN CHINA

This paper examines the Environmental Kuznets Curve (EKC) hypothesis for China in the presence of globalization. We have applied Bayer and Hanck combined cointegration test as well as the ARDL bounds testing approach to cointegration by accommodating structural breaks in the series. The causal relationship among the variables is investigated by applying the VECM causality framework. The study covers the period of 1970-2012. The results confirm the presence of cointegration among the variables. Furthermore, the EKC hypothesis is valid in China both in short-and-long runs. Coal consumption increases CO2 emissions significantly. The overall index and sub-indices of globalization indicate that globalization in China is decreasing CO2 emissions. The causality results reveal that economic growth causes CO2 emissions confirming the existence of the EKC hypothesis. The feedback effect exists between coal consumption and CO2 emissions. CO2 emissions Granger causes globalization (social, economic and political).

Finance and income inequality in Kazakhstan: evidence since transition with policy suggestions

ABSTRACT Kazakhstan gained independence in 1990 and has undergone significant changes in economic, social and trade conditions since then. We analyse the effects of financial development on income inequality in Kazakhstan, incorporating economic growth, foreign investment, education and the role of democracy as the drivers. We establish that income inequality in Kazakhstan is impaired by financial development. In summary, we send three messages for policy purposes. First, strengthening financial sector is necessary to close the gap between ‘haves and have-nots’. Second, attracting FDI beyond the hydrocarbon sector is necessary to alleviate inequality. Finally, adaptation of education system to the new social and economic environment would help in improving income distribution.

Adjustment of Profits: Evidence from Australian Manufacturing

Studies of industry profitability generally deal with long-run equilibrium models, making no allowance for slow adjustment to equilibrium. In this study, a cross-sectional analysis is carried out against a sample of Australian manufacturing industries at the Australian Standard Industrial Classification (ASIC) four-digit level between 1977–78 and 1984–85. Firstly, a profit model is estimated in equilibrium form as well as allowing for both uniform and variable adjustment rates across industries. The variable adjustment model is superior, with either model implying at least half adjustment to equilibrium within the seven-year sample period. Secondly, results are examined for the impact of firm homogeneity of firms within industries. Homogeneity of firms is found to have substantial impact,increasing both the estimated profits-concentration relationship and the estimated speed of adjustment.

Financial development, industrialization, the role of institutions and government: a comparative analysis between India and China

ABSTRACT This research is the first comparative attempt incorporating the role of economic, demographic, sectoral contribution, government and trade in explaining financial development for India and China. Using time-series estimations, we establish that institutional quality and government size impede financial development, whereas urbanization, industrialization and service sector growth help in financial development for both countries. Trade openness also enhances Indian financial development but hinders Chinese financial development. We suggest that the policy advisers should not underestimate the role of urbanization, industrialization and service sector growth in implementing financial development. Finally, we find that the institutions and governments will play a key role for both economies in enhancing finance and growth.
