In this paper, we seek to understand how changes in product architecture affect the innovation performance of firms in a complex product ecosystem. The canonical view in the literature is that changes in the technological dependencies between components, which define a product’s architecture, undermine the innovation efforts of incumbent firms because their product development efforts are built around existing architectures. We extend this prevailing view in arguing that component dependencies and changes in them affect firm innovation efforts via two principal mechanisms. First, component dependencies expand or constrain the choice set of firm component innovation efforts. From the perspective of any one component in a complex product (which we label the focal component), an increase in the flow of design information to the focal component from other (non-focal) components simultaneously increases the constraint on focal component firms in their choice of profitable R&D projects while decreasing the constraint on non-focal component firms. Second, asymmetries in component dependencies can confer disproportionate influence on some component firms in setting and dictating the trajectory of progress in the overall system. Increases in such asymmetric influence allow component firms to expand their innovation output. Using historical patenting data in the personal computer ecosystem, we develop fine-grained measures of interdependence between component technologies and changes in them over time. We find strong support for the empirical implications of our theory.

This chapter aims at providing an understanding of the research and devlopment (R&D) process in the pharmaceutical industry, by exploring the methodological challenges and approaches in the assessment of the determinants of innovation in the pharmaceutical industry. It (i) discusses possible methodological approaches to model occurrence of events; (ii) describes in detail competing risks duration models as the best methodological option in light of the nature of pharmaceutical R&D processes and data; (iii) concludes with an estimation strategy and overview of potential covariates that have been found to correlate with the likelihood of failure of R&D pharmaceutical projects.

This chapter presents a seven-part case developed for use in a graduate-level tax planning class. The case is organized in a taxpayer/business “life-cycle” approach. Over the semester the case follows a married couple as they consider a number of investments, start a business, and expand the business. As the case progresses, the couple faces increasingly complex tax and business issues. The couple eventually winds down their involvement in the business and begins to plan for their retirement years. This chapter also provides a review of behavioral tax research published in the top accounting journals over the period 2004–2013. The chapter concludes with a discussion of how the case could be adapted by behavioral tax researchers in their research programs and perhaps by accounting firms in their training programs.

Rather than organize as traditional firms, many of today’s companies organize as platforms that sit at the nexus of multiple exchange and production relationships. This chapter considers a most basic question of organization in platform contexts: the choice of boundaries. Herein, I investigate how classical economic theories of firm boundaries apply to platform-based organization and empirically study how executives made boundary choices in response to changing market and technical challenges in the early mobile computing industry (the predecessor to today’s smartphones). Rather than a strict or unavoidable tradeoff between “openness-versus-control,” most successful platform owners chose their boundaries in a way to simultaneously open-up to outside developers while maintaining coordination across the entire system.

This review integrates and builds linkages among existing theoretical and empirical literature from across disciplines to further broaden our understanding of the relationship between inequality, imprisonment, and health for black men. The review examines the health impact of prisons through an ecological theoretical perspective to understand how factors at multiple levels of the social ecology interact with prisons to potentially contribute to deleterious health effects and the exacerbation of race/ethnic health disparities.

This review finds that there are documented health disparities between inmates and non-inmates, but the casual mechanisms explaining this relationship are not well-understood. Prisons may interact with other societal systems – such as the family (microsystem), education, and healthcare systems (meso/exosystems), and systems of racial oppression (macrosystem) – to influence individual and population health.

The review also finds that research needs to move the discussion of the race effects in health and crime/justice disparities beyond the mere documentation of such differences toward a better understanding of their causes and effects at the level of individuals, communities, and other social ecologies.
