Are there limits to diversification in emerging economies? Distinguishing between firm?level and business group strategies

Abstract: The viability of unrelated diversification as a strategy in emerging economies is an unresolved puzzle. Because business groups dominate the landscape in these economies, and are known to diversify either by expanding the scope of existing affiliate firms and/or setting up new firms, we argue that it is important to make a distinction between firm‐level and business group‐level diversification. The results of our study covering the 15‐year period following India’s economic liberalization confirm our thesis. Whereas all firms, including business group affiliates, reduced unrelated scope to negotiate product and capital market pressures, business groups took advantage of the opportunity‐rich, post‐reform environment to enter into new unrelated businesses by setting up new affiliates. Our findings echo suggestions that as institutions strengthen, the locus of unrelated diversification moves away from managers of public corporations to entities with different types of ownership structures. We present the business group as one such ownership structure.

Obstacles to Success in the Workplace for People with Disabilities: A Review and Research Agenda

Abstract: Our objectives in this paper were to summarize research relevant to obstacles that people with disabilities (PWD) face in the workplace and to identify directions for future research on the topic. We included review, theoretical, and empirical articles in mainstream management journals and those in psychology or rehabilitation journals if they had clear workplace implications. We argue that obstacles identified in prior research may only partially reflect organizational reality. This is because of the heavy reliance on laboratory studies, which we urge researchers to replicate in organizational settings. Better understanding of obstacles will lead to more evidence-based solutions where the payoff is a less exclusionary world in which more individuals are provided opportunities to use their talent for the benefit of all.

Hybrid Cloud Computing Investment Strategies

Abstract: Cloud providers such as Amazon, IBM, and Microsoft are leasing their computing resources to various businesses providing them an alternative to investing in expensive hardware. Although recent information systems research has examined pricing‐related issues in cloud computing, several important questions still remain. For example, how should buyers decide on the capacity portfolio of private and public clouds? What is the impact of the buyer’s demand uncertainty on the capacity portfolio decision? We address these questions in this study through a stylized model. Our analysis reveals that the investment in cloud infrastructure (private, public or hybrid) is based on the profile of the buyer’s demand. When a buyer faces demand with low mean, she relies on public cloud solutions. If the demand has high mean, then the buyer firm hosts applications on a private cloud. Implementing a hybrid cloud is the optimal strategy when the mean demand is in mid‐range. We find that high demand variability makes businesses to move toward public cloud solutions. We support these insights through examples from practice in the cloud computing industry.

Electoral Uncertainty, Income Inequality and the Middle Class

Abstract: We investigate how increased electoral competition — by influencing the equilibrium policies of competing parties — affects the income distribution in society. Our model is embedded in a standard probabilistic voting setup where parties compete at two stages: (i) they allocate resources across various districts and (ii) then, for each district, they divide the resources among the different constituent groups. We show that an increase in electoral competition in a district results in a tendency towards equalization of incomes therein. We check for these relationships using data from the Indian national elections which are combined with household-level consumption expenditure data rounds from NSSO (1987-88 and 2004-05) to yield a panel of Indian districts. We find that districts which have experienced tight elections exhibit lower inequality and polarization which indicates a larger "middle class".

A generalized p-value approach for assessing noninferiority in a three-arm trial

Abstract: The existing generalized p-value approach, from statistical literature, is applied to assess noninferiority of an experimental treatment in a three-arm clinical trial including a placebo. Two generalized test functions (GTFs) are constructed and Monte Carlo simulations are used to compute the p-value. The GTFs perform well in terms of maintaining the Type-I error probabilities, and the power of the tests are shown to increase to 1 as both the sample size and the parameter denoting the fraction of the effect of the reference drug with respect to placebo increase. The generalized confidence intervals are shown to retain the coverage probabilities. A published dataset is re-analysed using the proposed test and the results are in agreement with earlier findings.
