Michael Grossman's seminal publication on the demand for health and health production (Grossman 1972) has spawned a substantial body of research focusing on the production of infant health. This article provides a systematic review of the published literature to date on infant health production and how it has evolved over the past 3–4 decades as data have become more available, computing has improved, and econometric methods have become more sophisticated. While empirical research in most fields has expanded in corresponding ways, the infant health production research has become an important part of the broader and inherently multidisciplinary literature on intergenerational health. The strongest and most robust findings are that policies matter for infant health, particularly those affecting access to health care, and that prenatal smoking and other chemical exposures substantially compromise infant health. Promising directions for future research include elucidating relevant pathways, reconciling the largely inconsistent estimated effects of nutrition and education, and exploring the roles of preconceptional and lifetime health care, paternal factors, social support, housing, complementarity and substitutability of inputs, factors that modify effects of inputs, and evolving medical technologies. 相似文献
This paper analyzes Stackelberg price leadership in a duopoly in which firms are capacity constrained and products are imperfect substitutes. Assuming symmetric substitutes, linear demand, and efficient rationing, we characterize the equilibria with an exogenously specified leader. Using the equilibrium profits derived from these games, we argue that over certain ranges of asymmetric capacities an endogenous price leader will emerge. When endogenous leadership does arise, it is the large capacity firm which is the leader. We thus provide a game theoretic model of dominant firm price leadership.Dave Furth's research has been undertaken as a part of the project Competition and Cooperation.

Many Human Resource (HR) professionals feel and believe that they have made progress during the 1980s. Unfortunately, without data to benchmark progress, assessments must depend on perception rather than evidence. To move beyond belief towards a national HR database, this article reports research on over 10,000 individuals in 1200 businesses in 91 firms. It establishes a benchmark for HR practices and HR professionals. It also highlights areas where HR professionals may focus attention to become more successful as business partners. 相似文献
Geoscientists are faced with a number of complexities that represent obstacles to the development of realistic simulation of deep earth processes. Realistic 4D thermo-mechanical simulation using software packages like Underworld and Gale, when combined appropriately with geoscientific expertise, can lead to novel insights into the deformation of geological structures at a wide range of time and spatial scales. The challenge for end-user geoscientists lies in applying their knowledge within the framework of the software’s input specification, including initial, internal, and boundary conditions and output visualization parameters. We have built a Graphical User Interface (GUI) to remove many of the difficulties related to editing the Extensible Markup Language (XML) encoded input files of Underworld/Gale geomodels and therefore, to greatly broaden the user base of these software packages. By helping Underworld/Gale to meet a large audience, we provide a tool to the geoscience community that helps to move from untested conceptual models to physically valid, properly scaled modelling. Furthermore, the UnderworldGUI offers a mechanism for storing and retrieving experimental models in a centralised database, thus providing the geoscience community with a means to share the outcomes of its experimental research. Further details of the UnderworldGUI are available at the web site http://www.wiki.vislab.usyd.edu.au/moinwiki/UnderworldGUI. 相似文献
In this Point–Counterpoint article we argue that institutional scholarship has become overly concerned with explaining institutions and institutional processes, notably at the level of the organization field, rather than with using them to explain and understand organizations. Especially missing is an attempt to gain a coherent, holistic account of how organizations are structured and managed. We also argue that when institutional theory does give attention to organizations it inappropriately treats them as though they are the same, or at least as though any differences are irrelevant for purposes of theory. We propose a return to the study of organizations with an emphasis upon comparative analysis, and suggest the institutional logics perspective as an appropriate means for doing so. 相似文献
This paper re-examines the empirical evidence on the degree of spatial spillover between university research and high technology innovations. The familiar Griliches–Jaffe knowledge production function is estimated at both the state and the metropolitan statistical areas (MSA) level and extended with more precise measures of spatial spillover. Alternatives based on the gravity potential and covering indices are formulated for Jaffe's “geographical coincidence index” and found to provide strong evidence of local spillovers at the state level. At the MSA level, a distinction is made between research and development activities and university research in the MSA and in the surrounding counties. Evidence is found of local spatial externalities between university research and high technology innovative activity, both directly and indirectly via private research and development. 相似文献
Before the debt crisis of 2010 forced Greece into almost permanent austerity, its hotel workers enjoyed wages and conditions (through a sector collective agreement) similar to those in other economic sectors. This was against the international trend where low wages and poor conditions were standard. Sweeping deregulation by Greek governments has brought much of the hotel industry into line with other countries. The sector agreement, now covering a much smaller proportion of the workforce, survived but has experienced ‘institutional conversion’, delivering a much poorer outcome. Despite buoyant tourism, institutional deregulation and derogation have delivered the employers' major objective of matching the workforce to the fluctuating demand for labour. 相似文献
University business incubators (UBIs) are an important part of the ecosystem that supports entrepreneurial activities and economic development. Extant research has focused on examining UBI activities at a single point in time, but there is a paucity of theoretical and empirical work aimed at understanding the forces that explain why and how UBIs change over time. This is an important gap because establishing a university business incubator does not assure its development and growth. We address this issue by drawing upon the Fisher et al. Academy of Management Review, 41(3), 383-409 (2016) Identity-Legitimacy-Life Cycle model to explain how the pursuit of resources and organizational legitimacy shapes the development of UBIs along key strategic and operational dimensions, which has implications for performance evaluation over time. We illustrate with a case study about the creation and evolution of the DMZ, a leading UBI at Ryerson University in Canada. This case provides new insights about the dynamics of UBIs and their relationships with the entrepreneurial ecosystems in which they are embedded. Implications for future research, management practice, and public policy are discussed.
