An examination of estimation and specification error biases in estimates of option prices generated by Black-Scholes and Cox-Ross models

In this paper the author identifies and examines the estimation and specification error biases of the Black-Scholes and Cox-Ross models by using both analytical and monte-carlo simulation techniques. Several hypotheses are tested. The central hypothesis is whether or not the estimation error bias in the correctly specified model is large enough to make researchers mistakenly pick the “wrong” model as being the “correct” one. The findings in this study support this hypothesis. It is shown that there is a bias toward accepting the Cox-Ross model as correct, even if the Black-Scholes is assumed to be the true model for pricing options.     

Efficiency differentials favouring resource-based industries

This note draws attention to some characteristics of resource-based industries, not mentioned in Roemer's (1979) recent survey on resource-based industrialization, which suggest that efficiency in these industries may be higher than in other LDC industries. Some empirical support is also provided.     

Welfare implications of growth under quotas

Using the standard trade model, it is shown that growth under quotas always improves welfare. This result is contrary to Johnson's (1967) result on the possibilities of immeserizing growth in the presence of tariffs.

Role of banks in financial inclusion in India

Financial inclusion is emerging as a new paradigm of economic growth that plays major role in driving away the poverty from the country. It refers to delivery of banking services to masses including privileged and disadvantaged people at an affordable terms and conditions. Financial inclusion is important priority of the country in terms of economic growth and advanceness of society. It enables to reduce the gap between rich and poor population. In the current scenario financial institutions are the robust pillars of progress, economic growth and development of the economy. The present study aims to examine the impact of financial inclusion on growth of the economy over a period of seven years. Secondary data is used which has been analyzed by multiple regression model as a main statistical tool. Results of the study found positive and significant impact of number of bank branch and Credit deposit ratio on GDP of the country, whereas an insignificant impact has been observed in case of ATMs growth on Indian GDP.     

Causal relationship between apparel exports and macroeconomic factors

Apparel exports make a significant contribution to economic growth in major apparel exporting economies such as Bangladesh, Sri Lanka and Vietnam. This study aims to investigate the causal relationship between apparel export growth and its determinants such as GDP growth, infrastructure, financial development, foreign direct investment (FDI) and labour productivity using panel data from 11 major apparel exporting countries for the period 1996 to 2013. The results confirm a long-run equilibrium association among the variables and reveal that GDP growth, infrastructure, financial development, FDI, and labour productivity have a significant positive influence on apparel export growth. Furthermore, the heterogeneous panel non-causality test results suggest that GDP growth, infrastructure and labour productivity contribute to apparel export growth in the short-run. These findings have several policy implications for the governments of the countries under study.     

Ethics and Accounting Education

Some aspects of ethics and accounting education are explored in this research. Research findings suggest that there is strong support for the inclusion of ethics in business and accounting curricula. The majority of respondents who responded to the ethics coverage question think that ethics should be integrated with all accounting courses. Moreover, the respondents are of the opinion that there are four main objectives of accounting education. These are: broad-based education, development of balanced skills, development of moral values and practical-biased programmes. The respondents also suggested different ways of implementing these objectives. The study further reveals that in ethics teaching, real examples and case studies should be used.     

Globalisation,economic growth and energy consumption in the BRICS region: The importance of asymmetries

This paper examines the asymmetric impact of globalisation and economic growth on energy consumption in BRICS countries, applying the NARDL bounds approach to explore the presence of asymmetric cointegration across variables. The empirical results reveal that energy consumption is positively and negatively affected by the positive and negative globalisation shocks, respectively. A positive shock in economic growth promotes energy consumption, while a negative shock reduces energy consumption.     

How does FDI affect domestic firms’ wages? theory and evidence from Vietnam

This paper explores the role of inward foreign direct investment (FDI) as a determinant of domestic firms’ wages, namely wage spillovers. We first construct a theoretical model to demonstrate that the presence of FDI firms affects domestic firms’ expected average wages via productivity spillovers and a cut-off capability. We then estimate FDI-induced wage spillovers by employing IV-GMM estimator with a five-year panel dataset of a growing service industry in Vietnam. Despite FDI firms on average pay 2.25 times that of domestic firms, they put a downward pressure on domestic firms’ wages. A one percent increase in FDI presence causes domestic firms to cut average wages by 2.03 percent. The estimations also find that firm-specific features are attributable to significant differences in their wages as well as FDI-linked wage spillovers.
