At the end of 2001, the Indian Supreme Court issued a directive ordering states to institute school lunches - known locally as midday meals - in government primary schools. In this paper we provide a large-scale assessment of the enrollment effects of India's midday meal scheme, which offers warm lunches, free of cost, to 120 million primary school children across India, and is the largest school feeding program in the world. To isolate the causal effect of the policy, we make use of its staggered implementation across Indian states in government but not private schools. Using a panel dataset of more than 420,000 schools observed annually from 2002 to 2004, we find that midday meals result in substantial increases in primary school enrollment, driven by early primary school responses to the program. Our results are robust to a wide range of specification tests.

Using a production function approach based on Cobb-Douglas, this analysis relates R&D efforts of 32 electric utilities on both sides of the Atlantic to their performance in terms of labour productivity. We find that higher R&D levels generally have a positive impact on revenues. However, only in the sub-sample of 16 electricity suppliers in Europe this effect is significant. Knowledge spill-over effects can be estimated for the US American sub-sample, since US utilities have bundled their R&D efforts in a centralized research institution and have to report that data. Our analysis reveals, though, that collaborative research efforts do not lead to positive spill-overs at the assumption of a time delay of one year. (c) 2015 Elsevier Ltd. All rights reserved....

Consumers often do not have complete information about the choices they face and, therefore, have to spend time and effort acquiring information. Because information acquisition is costly, consumers trade off the value of better information against its cost and make their final product choices based on imperfect information. We model this decision using the rational inattention approach and describe the rationally inattentive consumer's choice behavior when the consumer faces alternatives with different information costs. To this end, we introduce an information cost function that distinguishes between direct and implied information. We then analytically characterize the optimal choice probabilities. We find that nonuniform information costs can have a strong impact on product choice, which gets particularly conspicuous when the product alternatives are otherwise very similar. There are significant implications on how a seller should provide information about its products and how changes to the product set impacts consumer choice. For example, nonuniform information costs can lead to situations in which it is disadvantageous for the seller to provide easier access to information for a particular product and to situations in which the addition of an inferior (never chosen) product increases the market share of another existing product (i.e., failure of regularity). We also provide an algorithm to compute the optimal choice probabilities and discuss how our framework can be empirically estimated from suitable choice data.

Do conceptualizations of the information systems (IS) organization reflect findings from research studying requirements for successfully harnessing information, systems and technology to achieve operational and strategic objectives? This paper addresses this question, reporting on an analysis of articles published in leading academic and practitioner journals. It describes how the IS organization is portrayed in these studies and examines the results of this analysis through a sensitizing lens constructed from research that has studied how organizations generate business value from IS. The lens depicts this objective as a quest to harness knowledge that is distributed enterprise wide. The analysis suggests that conceptualisations of the IS organization used by researchers do not reflect the requirements for generating business value from information technology that have been identified in the literature. Whilst highlighting that definitions are vague or more often absent, it challenges the dominant orthodoxy of the IS organization as a separate organizational unit suggesting that it is a more pervasive construct. The implications of this conclusion for practice, research and teaching are considered.

With the onset of the 2020 coronavirus pandemic, industrial suppliers are increasingly challenged to close their open sales opportunities and keep generating business. Against this backdrop, the authors of this study investigate which offerings industrial customers are most likely to purchase as the pandemic progresses. Drawing on positive decision theory and empirically investigating 31,353 sales opportunities across 57 countries, the authors show that the coronavirus pandemic significantly decreases industrial customers' purchase probability, especially for high-priced offerings. In countries with low uncertainty avoidance and strong long-term orientation (e.g., China, India, Singapore), purchase probability is less affected by the pandemic. The coronavirus pandemic even increases purchase probability for offerings with low prices in countries where cultures are simultaneously uncertainty-avoidant and short-term oriented (e.g., Argentina, Brazil, Mexico). This is presumably because customers safeguard their operations in the face of impending supply shortages. Consequently, this helps suppliers focus on the right sales opportunities to secure their business during exogenous global shocks such as the coronavirus pandemic.

When organizations crowdsource ideas, they select only a small share of the ideas that contributors submit for implementation. If a contributor submits an idea to an organization for the first time (i.e., is a newcomer), and the organization does not select the idea, this may negatively affect the newcomer's relationship with the organization and willingness to submit ideas to the organization in future. We suggest that organizations can increase newcomers' willingness to submit further ideas by providing a thus far understudied form of feedback: rejections. Though counterintuitive, we suggest that rejections encourage newcomers to bond with an organization. Rejections signal contributors that an organization is interested in receiving their ideas and developing relationships with them. To test our theory, we examine the crowdsourcing of 70,159 organizations that received ideas from 1,336,154 contributors. Using text analysis, we examine differences in how rejections are written to disentangle the mechanisms through which rejections affect contributors' willingness to continue to interact with an organization. We find that receiving a rejection positively impacts newcomers' willingness to submit ideas in future. This effect is stronger if the rejection includes an explanation and is particularly pronounced if the explanation matches the original idea in terms of linguistic style.

This paper analyses how different types of access regulation to next generation networks affect investments and consumer welfare. The model consists of an investment stage with uncertain returns and subsequent quantity competition. The access price is a function of investment costs and the regulatory regime. A regime with fully distributed costs or a regulatory holiday induces highest investments, followed by risk-sharing and long run incremental costs regulation. Simulations indicate that risk-sharing creates most consumer welfare, followed by regimes with fully distributed costs, regulatory holiday and long run incremental costs, respectively. Risk-sharing benefits consumers as it combines relatively high ex-ante investment incentives with strong ex-post competitive intensity.

We study the effects of defaults on charitable giving in a large-scale field experiment on an online fundraising platform. We exogenously vary default options along two choice dimensions: the charitable donation decision and the "co-donation" decision regarding how much to contribute to supporting the platform. We document a strong effect of defaults on individual behavior but nevertheless find that aggregate donation levels are unaffected by defaults. In contrast, co-donations increase in the default amount. We complement our experimental results with a structural model that investigates whether personalizing defaults based on individuals' donation histories can increase donation revenues.
