Aligning incentives in supply chains

Most companies don't worry about the behavior of their supply chain partners. Instead, they expect the supply chain to work efficiently without interference, as if guided by Adam Smith's famed invisible hand. In their study of more than 50 supply networks, V.G. Narayanan and Ananth Raman found that companies often looked out for their own interests and ignored those of their network partners. Consequently, supply chains performed poorly. Those results aren't shocking when you consider that supply chains extend across several functions and many companies, each with its own priorities and goals. Yet all those functions and firms must pull in the same direction for a chain to deliver goods and services to consumers quickly and cost-effectively. According to the authors, a supply chain works well only if the risks, costs, and rewards of doing business are distributed fairly across the network. In fact, misaligned incentives are often the cause of excess inventory, stock-outs, incorrect forecasts, inadequate sales efforts, and even poor customer service. The fates of all supply chain partners are interlinked: If the firms work together to serve consumers, they will all win. However, they can do that only if incentives are aligned. Companies must acknowledge that the problem of incentive misalignment exists and then determine its root cause and align or redesign incentives. They can improve alignment by, for instance, adopting revenue-sharing contracts, using technology to track previously hidden information, or working with intermediaries to build trust among network partners. It's also important to periodically reassess incentives, because even top-performing networks find that changes in technology or business conditions alter the alignment of incentives.     

THE EFFECTS OF THE ANNOUNCEMENTS OF DIVIDEND INCREASES ON STOCK RETURN VOLATILITY: THE EVIDENCE FROM THE OPTIONS MARKET

This paper examines the impact of the announcements of dividend increases on the volatility of underlying stock returns implied by option prices, and analyses whether the impact is related to the label associated with the dividend increase. The results suggest that the announcements of labelled dividend increases are accompanied by a decrease in implied volatility, while the announcements of unlabelled increases in dividends are associated with no change in implied volatility. These results are consistent with the hypothesis that signal implicit in the announcements of dividend increases provides noisy information about the firm's volatility.     

Household Food Insecurity and Maternal and Child Nutritional Status: Evidence from Maharashtra

In this paper we rigorously examine the association of household food security status with maternal and child nutritional status exploring a rich micro‐level database, the Comprehensive Nutrition Survey Maharashtra 2012. Using Household Food Insecurity Access Scale (HFIAS) as a metric to measure household food security, we apply simultaneous probit models to estimate the effect of food insecurity on maternal and child nutritional outcomes. The modelling framework addresses possible endogeneity in the above relationship. Findings indicate that household food insecurity increases the risk of maternal and child underweight with no effect on child stunting, wasting or maternal overweight. Women’s decision‐making power mediates these associations. Food security interventions should be effective in tackling the concerns with undernutrition, however, food alone is not the solution. A mix of nutrition‐specific and nutrition‐sensitive policies is warranted. Food security interventions should be integrated into policies for human development.     

Bayesian estimation of discrete games of complete information

Estimation of discrete games of complete information, which have been applied to a variety of contexts such as market entry, technology adoption and peer effects, is challenging due to the presence of multiple equilibria. In this paper, we take a Bayesian MCMC approach to this problem, specifying a prior over multiple equilibrium selection mechanisms reflecting the analysts uncertainty over them. We develop a sampler, using the reversible jump algorithm to generate draws from the posterior distribution of parameters across these equilibrium selection rules. The algorithm is flexible in that it can be used both in situations where the equilibrium selection rule is identified and when it is not, and accommodates heterogeneity in equilibrium selection. We explore the methodology using both simulated data and two empirical applications, one in the context of joint consumption, using a dataset of casino visit decisions by married couples, and the second in the context of market entry by competing chains in the retail stationery market. We demonstrate the importance of accounting for multiple equilibrium selection rules in these applications and show that taking an empirical approach to the issue, such as the one we have demonstrated, can be useful.     

Consumers' willingness to pay for corporate social responsibility: Theory and evidence

In an era when consumers believe that businesses should engage in corporate social responsibility (CSR), it is vital to understand how it affects consumers' willingness to pay (WTP) for the goods and services offered by such businesses. There is a need for an in-depth study into the relationship between CSR and WTP, and to identify the mediators and the moderators affecting this relationship. To investigate this, we conducted a systematic literature review based on a preliminary search result of 116 unique articles indexed on this topic in four bibliographic databases—Scopus, Google Scholar, Dimensions and Web of Science—published over the previous seven decades. The findings confirm the overall positive effect of CSR on WTP. This study also reveals the indirect effect between CSR and WTP, mediated by variables like Brand Trust, Brand Loyalty, Brand Love, Customer Satisfaction, Brand Attitude, Purchase Intention and Brand Equity. The relationship is impacted by moderators, including demographics, cause-based aspects, company characteristics, personal aspects and types of products. The theory explaining the evidence of each of these aspects provides a deeper understanding of the relationship between CSR and WTP, and the intervening variables. Based on these, a conceptual framework of this relationship involving all the variables is developed. The Theory, Context and Method (TCM) framework is employed to identify gaps and systematically make recommendations for future research. The findings of this study will aid marketers in developing pricing strategies based on a thorough understanding of consumer behaviour in terms of CSR perceptions. Scholars can use this study's conceptual framework to examine previously unexplored relationships. As the literature on CSR and its influence on consumers' purchase behaviour grows, this comprehensive systematic literature review on the effects of CSR on WTP fills an important gap.     

Twenty-five years of Living Under Contract: Contract farming and agrarian change in the developing world

The expansion of contract farming schemes through regions of the developing world in the era of the globalization of agriculture raises questions that are central to the study of agrarian political economy. Contract farming has extended the footprint of commodity production and integrated land and labour not otherwise captured in forms of direct production and marketing. 25 years after the publication of Living Under Contract: Contract Farming and Agrarian Transformation in Sub-Saharan Africa, a foundational collection edited by Peter Little and Michael Watts, it is necessary to take stock of the most prominent developments in the practice of contract farming and in the political economy literature studying it. The ultimate contribution of Living Under Contract was framing contract farming as expressing the unevenness of power relations in agriculture and grounding it in specific political, historical and social contexts that were not examined in the mainstream accounts. This introduction to the special issue revisits the questions that have remained relevant or re-emerged in the political economy literature on contract farming; it raises new questions that reflect contemporary developments and it explains how the papers in this collection contribute to the expansion of the theoretical and empirical horizons of the research on contemporary contract farming in low and middle-income countries.
