Social Media Index Valuation: Impact of Technological,Social, Economic,and Ethical Dimensions

Marketing practitioners have recognized a growing need to measure consumer-generated social media in a standard way since there are numerous social media indicators in use, making intra- and inter-company comparisons difficult. This paper identifies four social media dimensions for measurement and evaluation: technological, social, economic, and ethical; and, subsequently, measures social media. The study makes a contribution to social media literature by using analytic hierarchy process of developing a mathematical model for social media index valuation. The “social media composite index number” will serve as an industry benchmark signifying the organization's share and commitment to social media.     

Financial crises and labor market turbulence

Financial crises in emerging markets trigger a significant reallocation of labor as exchange rate depreciations and interest rate increases cause relative prices to change drastically. Household survey data for Mexico reveal that individuals who switched industry or occupation during the 1994–1995 crisis lost about 10% of their hourly earnings on average compared to similar workers who did not move. This suggests that many workers became less productive in the process of migrating to different economic activities. These productivity losses, in turn, can explain about 40% of the observed fall in TFP in Mexico in 1995.     

Positive versus negative comparative advertising

Two studies examined cognitive responses to comparative advertising that was valenced, i.e., was either negative or positive. Negative comparative advertising featured the advertised brand derogating the comparison brand (I'm OK, you're not OK). Positive comparative advertising claimed superiority over the comparison brand in a nonderogatory manner (You're OK, I'm more OK). Subjects were exposed to either a negative comparative ad or a positive comparative ad. In study 1, the ad featured either a high or low share advertised brand and either a high or low share comparison brand while in study 2, the ad featured advertised and comparison brands with either a strong or a weak reputation. Across both studies, it was found that negative comparative advertising evoked significantly higher counterargumentation and lower claim acceptance than its positive counterpart. Also, when the advertised brand had a high share relative to the comparison brand, counterargumentation was lower and claim acceptance was higher vis-a-vis when the advertised brand had a low share relative to the comparison brand. Findings pertaining to brand reputation were mixed. Managerial and future research implications of the findings are discussed.     

Mobile banking in a developing economy: A customer-centric model for policy formulation

India needs inclusive growth to pull millions out of poverty. Despite the best efforts of mainstream financial institutions, financial exclusion is depriving millions of poor any chance to attain adequate standard of living. Telecommunication infrastructure growth especially mobile phone penetration has created an opportunity for providing financial inclusion. The current state of mobile banking is characterized by a top-down approach. This paper presents a bottom-up approach of designing mobile banking service which would be acceptable and accessible to the poor customers. The results point to clear preference of the urban poor for a joint bank–telecom led mobile banking model. Conjoint analysis of the data points to preference for attributes related to security/safety of a bank along with the coverage, accessibility and nimbleness of a telecom service provider with minimal documentation. The paper in its conclusion exhorts the regulators, telecom service providers and financial institutions to involve end-users in order to create a sustainable mobile banking service for financial inclusion.     

Forecasting stock market volatility and information content of implied volatility index

This study investigates the incremental information content of implied volatility index relative to the GARCH family models in forecasting volatility of the three Asia-Pacific stock markets, namely India, Australia and Hong Kong. To examine the in-sample information content, the conditional variance equations of GARCH family models are augmented by incorporating implied volatility index as an explanatory variable. The return-based realized variance and the range-based realized variance constructed from 5-min data are used as proxy for latent volatility. To assess the out-of-sample forecast performance, we generate one-day-ahead rolling forecasts and employ the Mincer–Zarnowitz regression and encompassing regression. We find that the inclusion of implied volatility index in the conditional variance equation of GARCH family model reduces volatility persistence and improves model fitness. The significant and positive coefficient of implied volatility index in the augmented GARCH family models suggests that it contains relevant information in describing the volatility process. The study finds that volatility index is a biased forecast but possesses relevant information in explaining future realized volatility. The results of encompassing regression suggest that implied volatility index contains additional information relevant for forecasting stock market volatility beyond the information contained in the GARCH family model forecasts.     

Farmers' Preference for Farming: Evidence From a Nationally Representative Farm Survey in India

Using data from a nationally representative farm survey in India, we have analyzed Indian farmers' stated preference for farming as a profession. Findings show that more than 40% of farmers dislike farming as a profession because of low profits, high risk, and lack of social status, yet they continue with it owing to a lack of opportunities outside agriculture. Farmers who express a preference for moving out of agriculture are mostly those with small landholdings, poor irrigation facilities, fewer productive assets including livestock, and follow a cereal‐centric cropping pattern. They also have relatively lower access to credit, insurance, and information, and are weakly integrated with social networks such as self‐help groups and farmers' organizations. Importantly, the disinclination for farming, conditional on other covariates, is not significantly differentiated by caste, an important indicator of social status in rural India. Yet, within a caste group, the dislike for farming moderates with larger landholdings.     

Wavelet Analysis of the Bombay Stock Exchange Index

The fluctuations in the rate of returns of the Bombay stock exchange are analyzed through wavelet transform. The fluctuations, in various time scales, naturally separated by the wavelets, are subjected to statistical analysis. The localization and multiresolution properties of the wavelets enable one to identify collective behaviour in the stock market and the extent of their influence at various time scales. The Gaussian nature of the rate of returns at certain scales and the periodic nature of the same, at other scales, are clearly brought out by this analysis. The utility of this approach for modeling purpose is also elucidated.

     

Are labor markets segmented in developing countries? A semiparametric approach

We test the hypothesis that observably similar workers earn higher wages in the formal sector than in the informal sector in developing nations. Using data from Argentina's household survey and various definitions of informal employment, we find that on average, formal wages are higher than informal wages. Parametric tests suggest that a formal premium remains after controlling for individual and establishment characteristics. However, this approach suffers from several econometric problems, which we address with semiparametric methods. The resulting formal premium estimates prove either small and insignificant, or negative. Neither do we find significant differences in measures of job satisfaction between the two sectors. We invoke these results to question the mainstream view that labor markets are segmented along formal/informal lines in developing nations such as Argentina.     

Balance of Payments and Related Issues in the Uruguay Round of Trade Negotiations

Little attention has been paid to the balance of payments provisionsof the General Agreement on Tariffs and Trade (GATT), despitethe fact that they directly influence the trade policies ofthe developing countries. This article suggests that there isa need to reconsider these provisions in the context of theongoing Uruguay Round of multilateral trade negotiations. Thearticle traces the historical evolution of GATT practices ontrade restrictions for balance of payments purposes. With thegeneral introduction of more flexible exchange rate arrangements,the original rationale for temporary barriers to safeguard acountry's external financial position appears to have lost itsforce. Recent theoretical and empirical work has demonstratedthat neutral or export promoting trade strategies are more effectivefor development than the import substitution frequently advocatedby economists in the 1950s and 1960s. The current debt problemsof developing countries strengthen the argument for a relativelyopen trade and payments regime to attain balance of paymentsviability. The article suggests that stronger internationaldiscipline over trade restrictions for balance of payments purposeswould contribute to and presuppose other necessary improvementsin the multilateral trading system which are already on theagenda of the Uruguay Round.     

An empirical study of the dimensionality of organizational justice and its relationship with organizational citizenship behaviour in the Indian context

Cross-cultural research shows that while the concerns about organizational justice may be universal, operationalization of justice standards is highly particularistic (Greenberg 2001). The present study explores the dimensionality of organizational justice in the Indian context. Apart from procedural justice, interpersonal justice and informational justice, another justice dimension, labelled as empowerment justice, emerged during the study. Next, the study tests the relationships between justice dimensions and Organ's (1988) 5-factor conceptualization of organizational citizenship behaviour (OCB), namely helping, compliance, sportsmanship, courtesy and civic virtue behaviours. The perception of empowerment justice influences helping, compliance, sportsmanship, and civic virtue dimensions of OCB. Interpersonal justice significantly predicts courtesy behaviour. Implications for theory and practice are discussed.
