The methodology applied was the mixed method under the multiple methods choices. Both qualitative and quantitative techniques were used. The findings were that formal education is not a pre-requisite requirement to the operations of a petty trading business. However, the study revealed the presence of accounting in petty trading; thus confirming the assumption that accounting is a universal good and is present in the petty trading business. Findings on the three major factors that influenced the present or absent of accounting among petty traders revealed that: there were no state institutions or pressure groups in Ghana to influence or oblige private entrepreneurs (petty traders) to prepare financial statements; the literacy of the petty trader though was found to be a necessary factor, it was not sufficient to explain the accountancy presence or absence in the traders' businesses. The usefulness of the accounting information to the petty trader influenced the presence of accounting in the traders' business. Finally, the level of trust - social capital in the community, and its influence on the presence of accounting, was relatively insignificant in the context of urban Ghana. No study of this kind has been conducted in the field of accounting presence or absence in Ghana. 展开更多

Based on trade in value-added, this paper has estimated the revealed comparative advantage (RCA) of China's various manufacturing sectors between 1995 and 2011 and compared with the RCA indexes measured using conventional aggregate accounting approach. Results indicate that: (1) the RCA index measured using conventional aggregate accounting approach has underestimated China's comparative advantage of labor-intensive sectors but overestimated China's comparative advantage in capital, knowledge and technology-intensive manufacturing sectors, giving rise to a serious misjudgment. (2) The RCA measured using value-added approach shows that in the industry chain layout of global manufacturing sectors, China's comparative advantage is still concentrated in labor-intensive manufacturing sectors but has signs of weakening; in capital, knowledge and technology-intensive sectors, China is yet to develop any significant comparative advantage; there are signs that China is developing comparative advantage in capital-intensive sectors yet China's comparative disadvantage in knowledge and technology-intensive sectors has no significant tendency to improve. This result not only helps correct the misjudgment of China's competitiveness in manufacturing sectors based on conventional aggregate accounting approach but offers important policy implications for setting strategic directions and policies for China's manufacturing transition and upgrade. 展开更多

Estimation of domestic and overseas value-added of manufacturing sector is an important and difficult subject for the science-based evaluation of a country's trade interests under global value chain. Traditional HIY approach overestimates the domestic value- added of export. Although Koopman's method made certain improvements, it cannot utilize traditional I/O matrix and direct input coefficient matrix under the condition of incomplete information. By creating GAMS model, this paper addresses the above-mentioned problems and employs an improved model for the estimation of variations in domestic and overseas value-added of Chinese exports between 2002 and 2012. Our results indicate that by neglecting the export of processing trade, HIY approach overestimates the domestic value- added ratio of Chinese exports. As more imported intermediate inputs have been used in the export of processing trade, the estimation result of this paper have corrected deviations in the forecast of overseas value-added ratio and its tendencies based on HIY method Further analysis of specific factors of domestic value-added of export led to the discovery that the domestic value-added of export of processing trade and mixed trade is highly vulnerable to the impact of international capital inflow. It can be seen that the improved method for the estimation of value-added has indeed corrected the deviations in the estimation of China's value-added. In conclusion, China should accelerate the development of export of non- processing trade and trade in high-end services, and balance the relationship of export between local firms and foreign-funded firms, with a view to improving trade dependence and increasing the trade status of Chinese manufaeturing firms in global value chain. 展开更多

Teacher evaluations intend to cultivate quality among teachers. However, since they are traditionally dependent on observers and their reports that are likely biased, the procedures probably effectuate discords among the calling-teaching professionals. An evaluation procedure that can ascertain fairness in the decisions about teacher retentions, terminations, promotions, and sanctions can capture the accordance of all teachers and teacher facilitators. This paper identifies the possibility of such an evaluation system that is built upon the existing value-added methods. Drawing upon the observations and recommendations by Chetty, Friedman, and Rockoff (2012) on value-added methods of evaluation, and considering the uniqueness of ELTs (English Language Teachers) as it was observed by Borg (2006) and Lee (2010), this paper describes the application of the value-added evaluation method, in gauging the quality of ELTs. The paper further explicates the vantages and conformities embodied in the procedure that could boost up the morale of ELTs as independent professionals of a creative art, and help them perform to their fullest potential 展开更多

Based on the Worm Input-Output Database (WIOD), this paper conducts a forward-linkage decomposition of value-added in trade to estimate China's service value-added exports and its service sector's international competitiveness during 2000- 2014. Result indicates that during the sample period, China's service exports measured by forward-linkage decomposition method accounted for around 35% in its total export. While the value of services exported directly through the service sector accounted for a falling share, the value of services exported through other sectors represented an increasing share. China ranks second in the world in terms of market share of service exports. However, the revealed comparative advantage (RCA) of China's service exports and export sophistication remains limited. 展开更多

This paper explains the root cause of China's trade surplus and argues that it is rooted in structural factors. China's dual economic structure and the relatively slow growth in wages due to the abundant supply of labor have led to a large supply glut between China's domestic demand and output, which has been balanced by export. This is a structural problem that cannot be solved by currency appreciation or the readjustment of capital account deficits. A potentially viable option is to adjust the current account by developing a new opening-up system featuring more freedom and compliance. 展开更多

The purpose of this paper is to create a comprehensive analysis of the development of foreign trade in the global world, the process of divergence of exports and imports under the influence political and economic changes in Europe and the economic crisis in the world. Data from world public databases are summarized to a clear and understandable form. We analyzed the share of imports and exports (due to the global trade is presented) and its potential impact on the development of current account balance (CAB) for the United States of America (USA), the European Union (EU), and China. Correlation coefficient timeline for the last decade of CAB and world trade is also presented to show the influence of trade flow in the world and the EU with respect to current account. The work emphasizes the clear and understandable processing of the required data, which are then formulated to make arguments and then used to make predictions of further development of world trade. From summarized data, future crisis can be predicted and impacts can be evaluated. 展开更多

Economists have recently become interested in weighting how much domestic value-added is actually included in China' s exports. Formally, the proportion of foreign and domestic contents could be identified by calculating the vertical specialization share using noncompetitive input-output tables. Applying such a method to the Chinese case, however, would result in a big measurement bias because China has a large share of processing exports, which utilize a disproportionately high percentage of imported intermediates. This paper, by directly employing 2008 trade data for which imported intermediates in both processing and non-processing trade could be identified by means of various trade patterns, provides a simplified way to estimate the share of foreign/domestic value-added included in industry-level manufactured exports. This paper finds that the vertical specialization share of China' s processing exports was about 56 percent in 2008, compared to about 10 percent for ordinary exports. It also finds that the sectors that experienced fast expansion of processing exports have a much higher share of foreign contents. Since processing exports accoant for about half of Chinese exports, the prevailing trade statistics, which focus on gross values rather than the value-added of exports and imports, has obviously overstated the bilateral trade imbalances, especially between China and the USA. 展开更多
