Estimating sensitive proportions from Warner’s randomized responses in alternative ways restricting to only distinct units sampled

Warner’s (J Am Stat Assoc 60:63–69, 1965) pioneering ‘randomized response’ (RR) technique (RRT), useful in unbiasedly estimating the proportion of people bearing a sensitive characteristic, is based exclusively on simple random sampling (SRS) with replacement (WR). Numerous developments that follow from it also use SRSWR and employ in estimation the mean of the RR’s yielded by each person everytime he/she is drawn in the sample. We examine how the accuracy in estimation alters when instead we use the mean of the RR’s from each distinct person sampled and also alternatively if the Horvitz and Thompson’s (HT, J Am Stat Assoc 47:663–685, 1952) method is employed for an SRSWR eliciting only, a single RR from each. Arnab’s (1999) approach of using repeated RR’s from each distinct person sampled is not taken up here to avoid algebraic complexity. Pathak’s (Sánkhya 24:287–302, 1962) results for direct response (DR) from SRSWR are modified with the use of such RR’s. Through simulations we present relative levels in accuracy in estimation by the above three alternative methods.     

When does leverage hurt productivity growth? A firm-level analysis

In the wake of the global financial crisis, several macroeconomic contributions have highlighted the risks of excessive credit expansion. In particular, too much finance can have a negative impact on growth. We examine the microeconomic foundations of this argument, positing a non-monotonic relationship between leverage and firm-level productivity growth in the spirit of the trade-off theory of capital structure. A threshold regression model estimated on a sample of Central and Eastern European countries confirms that TFP growth increases with leverage until the latter reaches a critical threshold beyond which leverage lowers TFP growth. This estimate can provide guidance to firms and policy makers on identifying “excessive” leverage. We find similar non-monotonic relationships between leverage and proxies for firm value. Our results are a first step in bridging the gap between the literature on optimal capital structure and the wider macro literature on the finance-growth nexus.     

Mixed Oligopoly,Privatization, and Strategic Trade Policy

This paper investigates the effects of privatization in the presence of strategic trade policies within an international mixed oligopoly serving a single market. If the government uses a domestic production subsidy, then welfare is always increased with privatization, while the optimal subsidy falls. If the government uses an import tariff, privatization increases welfare over much of the parameter space. The optimal tariff, however, may rise or fall.     

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.     

Identifying Key Success Factors for Social Enterprises Serving Base‐of‐Pyramid Markets through Analysis of Value Chain Complexities

There are people in this world who have little or no access to basic needs and they struggle financially, living on less than a handful of dollars a day. A better understanding of how to supply/serve the world's poor is needed. In this paper, through the lens of Porter's value chain framework we investigate the challenges and opportunities social enterprises face in base‐of‐pyramid (BoP) markets based on secondary data on 23 organizations. Our contribution is twofold: First, we analyze value chain complexities for the social enterprise based on the value creation role (consumer, coproducer) and income level (poverty, extreme poverty) of the local population. We find that nature of customers’ requirements varies across customer segments in the BoP markets and social enterprises face unique challenges in fulfilling such differentiated demand patterns. Second, we develop an affordability–accessibility framework that helps to identify the situations that may be favorable/unfavorable for social enterprises to meet the challenges in BoP markets. We make four propositions that social enterprises may use to cope with difficulties in affordability and accessibility. Our findings will be useful for such organizations to understand and design better supply chains for the base of pyramid.     

Do socially motivated self‐help groups perform better? Exploring determinants of micro‐credit groups’ performance in Eastern India

Group‐based micro‐credit initiatives, as part of the broader social and solidarity‐based finance initiatives, have gained prominence over the past decade, especially in developing economies like India. Lending to the poor, especially women, through micro‐credit groups, are significantly associated with the utilization of commons. Apart from their financial operations, self‐help groups promote social empowerment activities and collective action following a dual bottom‐line approach. However, the causal role of the group's motivation towards pursuing social objectives has not been explored in the past. The present study, therefore, investigates the interlinkages between the group's intrinsic motivation and efficiency using an innovative two‐stage double bootstrapped DEA‐based methodology. Results from the study affirm that apart from traditional factors like maturity, accessibility and group management, the motivation of the group is a crucial determinant of social efficiency. Additionally, the group's loan‐to‐savings ratio and receipt of cash payments significantly affect its long‐term financial sustainability. Micro‐credit groups cannot contribute sustainably as a viable alternative to traditional means of access to credit if it merely offers innovative forms of financing and consumption. They need to be socially aligned to serve the community better and contribute to the group's overall performance and galvanize community‐based resource management.     

Computing the Extent of Circumvention of Proposition 13: A Note

We analyze the own-source revenues of California state and local governments relative to the State's personal income in order to examine the extent to which the growth in non-tax revenues has circumvented the reduction in taxes produced by Proposition 13. Our results show that, while non-tax revenues have been the favored means to circumvent California's fiscal constitution, the circumvention has been only marginal.     

Multi-item EOQ model while demand is sales price and price break sensitive

In this paper, the authors study a multi-item deterministic EOQ (economic order quantity) model for a vendor when the demand rate of the essential commodities decreases quadratically with increasing sales price and increase exponentially with increasing level of price breaks. A price discount is offered to the customers when the revenue of the vendor crosses the level of price break. The main aim of the present article is to find out the optimal order quantities, optimal selling prices and optimal level of price break in order to maximize the average profit of the whole products. Numerical examples are also illustrated to test of our proposed model.
