Health-Care Payment Systems: Cost and Quality Incentives—Comment

This note analyzes the incentives for cost reduction that different payment policies provide to profit-maximizing health-care providers. Ching-to Albert Ma (1994) proposes a reimbursement mechanism that seeks to induce first-best cost reduction by using a combination of cost reimbursement and prospective payment in a model where higher effort on the part of the health-care provider reduces treatment costs. This note shows that a mechanism of this type, generally, will not result in first-best cost reduction. However, such a mechanism is optimal when the payer has efficiency and distributional concerns.     

A configural framework of practice change for B corporations

There is increasing scholarly attention toward understanding how enterprises seeking prosocial impact organize their practices. However, this research has primarily explained changes in isolated practices and has not fully explored the mechanisms for such changes. This omission is relevant for social entrepreneurship scholars who seek to better understand how practices operate not simply internally but can effect a positive impact. We address this omission by drawing from a unique longitudinal dataset – assessment scores of enterprises seeking to be certified and recertified as B Corporations (B Corps). We also conducted 24 interviews with B Corp leaders, B Lab staff, and venture fund managers. We found that B Corps shifted their practice configurations as they underwent assessment and reassessment for certification. We also found that exogenous factors such as size and sector, and endogenous factors such as the nature of practices explained shifts in practice configurations. Our contribution is twofold. First, we test deductive claims that social enterprises re-organize for impact. We show that enterprises update their practice configurations over time. Second, we propose an inductively derived theoretical framework with three building blocks: affordability, interpretability, and social referents to explain the shifts in practice configurations.

Integrated modeling for exploring sustainable agriculture futures

Sustainable agriculture meets human needs for food, enhances the quality of life of people, protects the integrity of natural systems, and is economically profitable. Making a transition to agricultural sustainability involves difficult choices and an understanding of the complex trade-offs associated with different agricultural pathways. In this paper, we describe the development and application of a decision support tool—AgFutures—for exploring alternative futures for agricultural sustainability in the Lower Mainland of British Columbia. The main core of the model is simulation of future land-use changes in different scenarios and assessment of social, economic and environmental consequences under these scenarios. Evolution of land-use is simulated as a result of not only biophysical conditions but also as a result of human behaviour and choices, specifically related to lifestyle, agricultural management practices and institutional policies. Eight different scenarios are generated and compared for their impacts on sustainability in the Lower Mainland.AgFutures helps users to identify desirable future scenarios and the set of choices and trade-offs that they are willing to accept. Identification of these allows decision-makers to formulate policies that would lead to achieving the goals of sustainable agriculture. The novel aspect of this model lies in its design and methods, which represent a balance between the need for rigour and the need for a tool that can be used by a wide array of users.     

Resistance to technological innovations: An examination of the role of self-efficacy and performance satisfaction

Technological innovation is seen as the key to survival and success for many firms. Whether intended for internal use or for customers, adoption decisions must consider the response of the final user to such technological alternatives. This paper argues for greater attention to the factors which cause individual resistance to technological innovations. The results of two studies are reported which examined the effects of self-efficacy (Bandura 1977) and performance satisfaction on consumers’ response to technological changes. Results indicate that a person’s perceived ability to use a product successfully affects their evaluative and behavioral response to the product. In addition, the level of satisfaction experienced with an existing behavior increases resistance to and reduces likelihood of adopting an alternative.     

Relative information functions and their type (α, β) generalizations

The concept of relative information functions by means of a functional equation under suitable boundary conditions is introduced and discussed. Further the relative information is defined in terms of these functions and this idea is extended to the new concept of relative information functions of type (α, β) (α, β>0, α≠β) and relative information of type (α,β) which are the generalizations of the earlier ones. Finally the different types of relative informations of type (α, β) are defined for bivariate distributions and the relations between them are established.     

Dealing with the Contagion： China and India in the Aftermath of the Subprime Meltdown

What began as a downturn in the US housing sector in the summer of 2007 had mushroomed into a global financial crisis by September 2008： the most severe since the 1930s. Developing countries, including China and India, at first seemingly sheltered from the worst of the turmoil, have not been immune to the contagion＇s spillover effects. What are China and India＇s precise vulnerabilities, and what can each do to better insulate their economies from the vagaries of global financial marker turmoil？ Equally important, what long-term strategies must each country adopt to make their economies more resilient to global market downturns？     

An Analysis of Exports and Growth in India: Cointegration and Causality Evidence (1971–2001)

The relationship between exports and economic growth has been analysed by a number of recent empirical studies. This paper re‐examines the sources of growth for the period 1971–2001 for India. It builds upon Feder's (1983 ) model to investigate empirically the relationship between export growth and GDP growth (the export led growth hypothesis), using recent data from the Reserve Bank of India, and by focusing on GDP growth and GDP growth net of exports. We investigate the following hypotheses: (i) whether exports, imports and GDP are cointegrated using the Johansen approach and Breitung's nonparametric cointegration test; (ii) whether export growth Granger causes GDP growth; (iii) and whether export growth Granger causes investment. Finally, a VAR is constructed and impulse response functions (IRFs) are employed to investigate the effects of macroeconomic shocks.     

Short-term fluctuations in hospital demand: implications for admission, discharge, and discriminatory behavior

We analyze admission and discharge decisions when hospitals become capacity constrained on high-demand days, and develop a test for discrimination that, under certain circumstances, does not require controls for differences across patient groups. On high-demand days, patients are discharged earlier than expected compared to those discharged on low-demand days. High demand creates no statistically significant differences in hospitals' admission behavior. Thus, hospitals appear to ration capacity by hastening discharges rather than by restricting admissions. We could not reject a null hypothesis of no discrimination against Medicaid patients in discharges     

Google: The World’s First Information Utility?

In only ten years, Google has achieved remarkable success from online search-based advertising. Its search engine is dominant, and its IT infrastructure is the most powerful computing system in the world running on over one million computers and serving more than one billion users globally. Google makes money by using its search engine to deliver online advertising alongside responses to user searches for information, goods, maps, directions, and a host of other services. Its capabilities make it likely to become the world’s first information utility – a concept similar to electric utilities that provide services to many corporations and individuals alike. Constant innovation is the key to Google’s success and offers lessons for other companies: hire talented people, have them work in small teams, and give them freedom to excel, but use a rigorous data-based approach to evaluating results and making course adjustments.
