On the exact variance of an unbiased product type estimator and its comparison with the sample mean

We consider the usual product estimator adjusted for its bias, considered by Robson (1957). The exact variance of this estimator has been obtained through a direct method. Its superiority over the sample mean and the product estimator is demonstrated. The research of these authors has been partially supported by their respective NSERC grants A3661 and A3989.     

Delayed monsoon,irrigation and crop yields

Most of the empirical literature assessing the impacts of climate change on agriculture has modeled crop yields as a function of the levels or deviations in the growing-period rainfall. However, an aspect that has received little attention in the empirical literature relates to the relationship between the timing of monsoon rains and crop yields. Using a pan-India district-level panel dataset for 50 years, this article investigates two interrelated issues critical to understanding the impacts of weather-induced agricultural risks and their management. It first examines the impact of the timing of monsoon onset on crop yields and then assesses the role of irrigation in mitigating its effects. The article finds that the delayed onset of monsoon is detrimental to crops, and its effects are realized beyond the rainy season. The findings also demonstrate that irrigation helps mitigate the harmful effects of delayed monsoon. Finally, to link these findings to farm-level adjustments, the article shows that farmers explicitly adjust the timing of irrigation in response to delays in monsoon rains.     

Normative influence and masstige purchase intention: Facilitators,inhibitors, and the moderating effect of celebrity endorsement

Masstige marketing has gained considerable attention in the recent past as a theoretically significant and practically relevant concept. Masstige strategy encompasses all those activities directed to position the products for the masses, neither by offering drastic price reductions nor discounts. Rather its success depends on product innovation and promotion. Although it has been recognized as an important strategic construct, the nascent concept needs further investigation for better understanding. This research identifies significant gaps in the extant literature on fashion accessories masstige brands and intends to bridge them. The objective of the current study is to empirically investigate the factors that facilitate or inhibit masstige purchase intentions. Our study uncovers the role of normative influence in influencing the purchase intentions of a masstige fashion accessory brand, that is, Armani Exchange. Data were collected from 395 respondents, and structural equation modeling was applied to check the proposed hypotheses. The study's results revealed that conspicuous and social values play an important role as facilitators. In addition, the study highlighted that masstige brands need to overcome inhibitors like identity avoidance and deficit-value avoidance to develop masstige purchase intention. Moderation analysis highlighted the significant influence of celebrity endorsement in strengthening the facilitators and overcoming inhibitors associated with masstige purchase intention. The study's results can help marketers to position their masstige brands by adopting the right strategies that can be formulated by taking into account the influence of stimulus, facilitators, inhibitors, and a moderating variable examined in the study.

Insider stock pledging and stock price informativeness: Evidence from India

Insiders’ shares can act as collateral while raising funds from lenders. This study examines the impact of insiders’ stock pledging activities on stock price informativeness using a sample of 1835 Indian firms. Our findings report that insider stock pledging increases the informational efficiency of stock prices. This informational efficiency increases for larger firms with: (1) financial constraints (high leverage and low cash holdings); (2) greater reliance on trade credit; and (3) higher indulgence in related party transactions. We also provide evidence on abnormal share turnover as a trading mechanism through which insider stock pledging is related to stock price informativeness. Our findings are robust across different specifications and after accounting for endogeneity issues.
