The case has the following learning objectives:

1. understand the various types of comparisons that are possible between groups over time and across space;

2. evaluate a policy intervention using relevant data and different methods; and

3. understand the meaning of the phrase “controlling for other relevant factors” in regression and non-regression contexts.

The difference-in-differences (DID) approach is a useful tool for making meaningful comparisons. This case tries to provide a non-technical introduction to the approach using a basic comparison of crime rates among districts in Punjab (Pakistan's largest province). Being the most populous region of the country, Punjab faces many governance challenges, and street crime is one of them. (Exhibit 5 provides additional information about the geographical and administrative setting used in this case study.) In 2016, Chief Minister Shahbaz Sharif established the Dolphin (police) Force in different locations to improve urban patrolling and reduce street crime. There were debates about the effectiveness of the Dolphin Force (DF).

Those who are skeptical of DF point to various situations that were handled incorrectly by DF personnel, as well as other administrative and operational problems in the initiative. Optimists believe it is beneficial and want it to be expanded to other districts and regions. The threat of street crime claims many lives and, according to optimists, necessitates the formation of a special force. Whether the huge resources invested in the DF worth their lot or not can be known through sound statistical analysis that can identify the difference in the rate of crime because of the DF. In this instance, the case provides information to answer the following question:

Is there a significant difference in crime rates between areas where the DF is operating and districts where it has not yet been installed?

In quantitative/statistical analysis classes, the case can be used to teach the DID technique to MBA/MS Applied Statistics/Applied Data Analysis students. It can also be used in undergraduate Econometrics classes.

CSS 7: Management Science.

In early 2017, after launching its successful “Greenhouse-in-a-Box” pilot project in India with fifteen smallholder farmers, Kheyti, a non-profit agricultural technology (AgTech) social enterprise, was struggling with several decisions in developing and growing its business. Kheyti was launched in 2015 to help smallholder farmers battle poverty and income variability by providing affordable technologies bundled with services. Over eighteen months, the team had developed a low-cost and modular greenhouse product to which it added financing, inputs, training, and market linkages to create a comprehensive “full-stack” solution for small farmers. The pilot project was a success in many ways, but Saumya, Kheyti's co-founder and head of product, was concerned that it revealed shortcomings that could severely affect the viability and scalability of Kheyti's solution.

Saumya had some important decisions to make. Should Kheyti redesign the product from scratch, or find other ways to reduce the cost for early adopters? Should it rely on upfront revenues from sales of the greenhouse, or consider developing an innovative financing or contract farming model? Kheyti's dwindling cash reserves meant that these decisions were urgent and critical. The path chosen now would determine whether the startup would move beyond the pilot stage and achieve its vision of serving 1 million farmers by 2025.

The case documents the evolution of an eye care hospital promoted by a not-for profit organization located in Mandvi, Surat, close to the tribal community of Gujarat state, India. In a short span of five years (as of 2016), the trust has evolved as a community hospital. The value proposition of the trust is a portfolio of activities, which includes awareness by education, prevention of eye care diseases through eye screening camps, treatment, and rehabilitation on need basis and addressing direct and indirect healthcare needs of the community. The managerial challenge before the board of trustees is to carefully balance (a) The purpose for which the trust was created, (b) the gap between the ground realities and the need in the relevant tribal community (c) the accomplishments of the eye hospital so far.

This case explains marketing process for follow-on equity offerings, the direct and indirect costs of issue, and the long-run performance of equity issuers. Students use analysts' projections from which to estimate the intrinsic value of the company's share—including the cost savings from the VEBA and financial improvements over the next several years. It is appropriate for use in corporate finance courses covering the topics of capital raising, equity financing, capital structure, costs of financing, funding alternatives, investment banking, and valuation. It presents the classic profile on an equity issuer—a firm whose stock price has risen to new heights in recent months. Will the issue lead to additional value that creates opportunities for shareholders, or is it a sign the firm is overvalued? The case explores the thinking of a prominent investment manager who had accumulated a large stake in Goodyear and who did not see the need for Goodyear to make an equity issue at this time. The company's position was that the high stock would allow it to further strengthen its balance sheet and pursue international growth opportunities. Students are asked to decide what the investor should do with respect to the current offer—buy, sell, or hold.

This case is intended to be part of a first-year MBA marketing course, or a second-year elective in advertising, integrated marketing communications, market research, or marketing analytics. The case provides students with examples of two real advertising experiments and the challenges involved in executing the experiments. It allows for a discussion of the need for advertising experiments, and also, at a more general level, the need to measure the return on marketing. Biases surrounding the field experiments allow for a discussion of the problems with establishing a causal relationship between advertising and sales.

Entrepreneurship, Business Strategy.

The case is designed for business students at the undergraduate or MBA levels in courses that deal with social entrepreneurship. The case describes the future growth potential of the exotic vegetable/fruit market in emerging economy India and lends itself for use in Rural Management courses as well.

Nisarg Nirman Agro Products Private Limited (hereafter referred as NNPL), a social farming venture, was started by Anjali Churi in the year 1997 in India. Churi, an agriculturist at heart, was always interested in experimenting and conducting research on new crops. What started as a small research experiment soon prospered to become a commercial venture producing and selling exotic vegetables to the Indian business customers, such as the five-/four-star hotels, premier clubs, hypermarkets, etc. NNPL was one among the pioneers to start the cultivation of exotic vegetables in the country. Their indigenous produce was of high quality. Their business customers were benefitted by the freshness of their products as well as competitive pricing as compared to their earlier imports. In her journey to commercial prosperity, she adopted co-operative farming, thus providing employment and livelihood opportunities to Indian farmers. Over the period, NNPL was invited to provide agriculture consulting to some of the other countries, such as Maldives, Thailand and Israel. In 2014, the company boasted of an indigenous produce of 95 different varieties of exotic vegetables and fruits, with 34 clients across the country, revenues to the tune of INR40 million and touching lives of more than 600 farmers across the country. The Indian exotic vegetables market had a promising future. Churi desired to expand her venture but in a manner that could systematically impact and generate employment opportunities for the rural Indians. She was at crossroads to deciding what could be such a venture, agro-processing or agro-tourism? Any such expansions required substantial investments for agricultural research activities. The case is structured to achieve the following pedagogical objectives: a social entrepreneur's ability to identify and exploit the market opportunity for growing own venture as well as generating a larger social impact; understand the industry's change trajectory and its impact on the venture; understand the importance of such business models of cooperative farming in populous emerging economies such as India where 70 per cent of the population resides in rural India.

The case that maps the growth/challenges of a social farming venture and allows students to: understand that small social venture also has the ability to generate a larger social impact; evaluate the venture's strategic positioning and scope in a competitive environment; and evaluate the need and potential of business models as cooperative farming to generate employment at the base of the pyramid in populous emerging economy as India.

Strategic Management.

The case is designed for a) MBA students b) Short-duration executive MBA courses.

The case refers to India’s leading steel company Tata Steel. Tata Tiscon, the steel rebar brand, is the organization’s leading retail brand. The case chronicles the period between the birth of the retail brand in the year 2000, its dramatic rise and dominance, to the end of 2013 when some of its initiatives had failed. Tata Tiscon was established as a pan Indian brand on the dint of a distribution network comprising 33 distributors and over 2000 retailers, many of them exclusive to the brand. The brand spawned a series of innovation in the category like “selling by piece”, fixed price concept and “free” home delivery. Together with its channel partners, the company achieved dramatic success which was reflected in its leading market share coupled with significant price premium in a category where price had traditionally being the only selling pitch. After 2010, the company saw an emerging challenge in the form of a new business model, where some companies were gearing to provide the complete portfolio of construction material including cement, steel, etc., and a turnkey construction solution for house builders. Tata Tiscon responded by attempting to enter the service space by launching a building design solution and later a construction supervision solution. Both of these initiatives failed. The protagonist of the case is Mr Keshav Viswanath (Chief of Marketing for retail business at Tata Steel), who is concerned with the failures of these key initiatives and is wondering how to ensure the “leader” status of Tata Tiscon in coming years.

The students are expected to understand how a core strategy like differentiation is implemented successfully in “practice”; understand the exploitation–exploration dichotomy in an organization; appreciate difference between radical innovation (based on new organizational routines, new business partners and new relationships) and incremental innovation based on fine tuning of existing organizational routines and relationships.

CSS 11: Strategy.

This case will lead students to a discussion of the causes and effects of hyperinflation. The link with fiscal deficits is explored, and so is the link with societal changes. The particular focus is on the hyperinflation in Zimbabwe under President Robert Mugabe whose government implemented a controversial land redistribution program. The case can be taught with a class experiment—see teaching note.

This case was primarily researched using academic research papers, industry reports (Egg Industry Center and others), and finance databases including Standard and Poor’s Capital IQ. Regarding the cost and investment budgets, the case relies mainly on an experiment conducted by the Coalition for Sustainable Egg Supply, updated by the authors of this case.

Eggs produced by cage-free birds, while more expensive than conventionally produced eggs, are gaining in popularity among consumers who want only eggs that are produced more humanely. A number of major distributors, including Whole Foods, McDonalds and Starbucks have pledged to sell only cage-free produced eggs by 2025. Several states including California, Oregon and Michigan have passed laws limiting conventional egg production. The case provides costs and industry information and needed to project free cash flows and risk-adjusted opportunity cost of capital and perform break-even capital budgeting analysis of the two egg production alternatives.

This case is appropriate for graduate corporate finance courses. It is particularly appropriate for agribusiness finance courses. A preliminary exercise was used during the fall 2018 in a land grant university, just after the “Prevention of Cruelty to Farm Animals Act,” also known as Proposition 12, was passed in California in favor of cage-free egg production. The exercise was revised and used in the fall 2019 in the same class. This extended version of the case, was classroom tested in the fall 2020 in an agribusiness finance graduate class, with agricultural economics and business students enrolled.
