A stochastic dominance approach to program evaluation with an application to child nutritional status in Kenya

Most existing program evaluation methods examine the average impact of a program. This necessarily overlooks the potential for different program impacts over different parts of the distribution of the variable of interest. To overcome this limitation, we develop a novel methodology for program evaluation which combines stochastic dominance with difference-in-differences methods. We use this new method to evaluate the impact of a large decentralization program in Kenya on changes in child nutritional status, where one's primary concern is about sharp adverse (i.e., negative) changes. Using standard difference-in-differences regression as a baseline, we find , no statistically or practically significant mean impact. In contrast, our stochastic dominance estimations reveal that project expenditures have had different impacts on different parts of the distribution. In particular, they are associated with less deterioration in children's nutritional status among the worst-off children, indicating that the program effectively functions as a nutritional safety net.     

A bed management strategy for overcrowding in the emergency department

In 2006, the Institute of Medicine cited growing visit volumes, hospital closures, financial pressures, and operational inefficiencies as the principal reasons for emergency department (ED) overcrowding and called for regulatory measures to resolve the problem. A Midwest medical center with 59,000 annual ED visits instituted a bed management strategy to decrease the need to board, or hold, admitted hospital patients in the ED awaiting transfer to an inpatient care unit. This strategy was successful in improving the hold time from an average of 216 minutes to 103 minutes, or by 52%. This allowed the staff at the hospital to care for an additional 2,936 patients. During this same time, the overall hospital mortality decreased by 0.07% and patient satisfaction scores improved 1%. The greatest outcome from this intervention was realized in the potential revenue increase of over $2 million.     

Justifying health IT investments: A process model of framing practices and reputational value

Despite important research contributions on the financial and operational dimensions of information technology (IT) value, justifying health IT (HIT) investments remains a difficult and enduring issue for IT managers. Recent work has expanded our understanding of HIT value, by focusing on the initial resource allocation stage, and through conceptualizations of value across multiple dimensions. Building on these developments, we adopt a performative perspective to examine the research question of how practitioners justify early stage HIT investments, with a focus on reputational value. We explored this question through a comparative field study of two hospital organizations in the English National Health Service (NHS). We found that practitioners' temporally orientated framing practices matter in justifying HIT investments, enacting different possibilities for reputational value. We develop a process model to explain these dynamics and highlight the mutability of reputational value, which can lead to different possibilities for restoring, enhancing, or maintaining reputation. We conclude by discussing the implications for justifying HIT investments.     

Enforced Tourists: American Women,Travel, and the ‘Far-Flung Fronts’ of World War II

The exigencies of World War II resulted in a massive expansion of travel opportunities for American women, both civilian and military, that formed an essential ingredient of their wartime experience. As enforced tourists, the geographical centres and states of knowledge of American women were greatly expanded as they travelled to distant and remote areas, met new people, took on new jobs, encountered different cultures and ways of life, and established themselves and their families in unknown locations. The far-reaching consequences of enforced wartime travel played an important role in transforming the way American women thought about themselves and their world, and the legacy of the war continues to reverberate in women's lives. Much has been written about how major wars have given rise to postwar pilgrimages, battlefield tours, and the establishment of commemorative memorials and museums, but the significance of enforced tourists who travelled during wartime itself has not been fully explored. The far-reaching consequences of wartime travel and the extent to which it transforms the lives of enforced tourists – both women and men, civilian and military – is a largely uncharted topic worthy of considerable attention by scholars.     

An Ordered Tobit Model of Market Participation: Evidence from Kenya and Ethiopia

Do rural households in developing countries make market participation and volume decisions simultaneously or sequentially? This article develops a two-stage econometric method to test between these two competing hypotheses regarding household-level marketing behavior. The first stage models the household's choice of whether to be a net buyer, autarkic, or a net seller in the market. The second stage models the quantity bought (sold) for net buyers (sellers) based on observable household characteristics. Using household data from Kenyan and Ethiopian livestock markets, we find evidence in favor of sequential decision making, the welfare implications of which we discuss.     

Information internalisation and internationalisation—Evidence from Vietnamese firms

Previous research on internationalisation has mainly focused on the collection and use of information. In this article we examine the role of information internalisation in international business activities of Vietnamese firms. A theoretical model incorporating key antecedents and outcomes of information internalisation is developed. The antecedents are market orientation and learning orientation, and the outcomes are international orientation and foreign sales intensity. A survey of 144 Vietnamese internationalising firms was conducted to test the model in conjunction with its two competing models by means of a two-step approach to structural equation modelling. We found that both information internalisation has direct and indirect effects (mediated by international orientation) on foreign sales intensity. Further, market orientation and learning orientation underlie information internalisation. Implications for managers and directions for future research are also addressed.     

Towards a global food aid compact

Existing international mechanisms governing food aid are dysfunctional and outdated. A reasonably straightforward alternative could readily rectify the problem of an ineffective global food aid governance system. In this paper, we outline the basic design of such a Global Food Aid Compact.
