Attendee-Sourcing: Exploring The Design Space of Community-Informed Conference Scheduling

Constructing a good conference schedule for a large multi-track conference needs to take into account the preferences and constraints of organizers, authors, and attendees. Creating a schedule which has fewer conflicts for authors and attendees, and thematically coherent sessions is a challenging task. Cobi introduced an alternative approach to conference scheduling by engaging the community to play an active role in the planning process. The current Cobi pipeline consists of committee-sourcing and author-sourcing to plan a conference schedule. We further explore the design space of community-sourcing by introducing attendee-sourcing -- a process that collects input from conference attendees and encodes them as preferences and constraints for creating sessions and schedule. For CHI 2014, a large multi-track conference in human-computer interaction with more than 3,000 attendees and 1,000 authors, we collected attendees' preferences by making available all the accepted papers at the conference on a paper recommendation tool we built called Confer, for a period of 45 days before announcing the conference program (sessions and schedule). We compare the preferences marked on Confer with the preferences collected from Cobi's author-sourcing approach. We show that attendee-sourcing can provide insights beyond what can be discovered by author-sourcing. For CHI 2014, the results show value in the method and attendees' participation. It produces data that provides more alternatives in scheduling and complements data collected from other methods for creating coherent sessions and reducing conflicts.Comment: HCOMP 201

Why do Firms Engage in Multi-sourcing?

We provide an explanation for multi-sourcing, which is often found in the real world and refers to the situation where a final goods producer acquires homogenous components from different suppliers. In the presence of imitation under outsourcing, multi-sourcing helps to deter entry by the suppliers into the final goods market and enhances profitability of the outsourcing firm.Entry, Imitation, Multi-sourcing

A domain-specific modeling technique for value-driven strategic sourcing

Strategic sourcing recognizes that procurement should support a firm’s effort to achieve its long-term objectives. In particular, procurement needs to be a cross-functional end-to-end process inside the organization that is oriented towards value creation within the company and between the company and its partners in the value chain. The main challenge to the implementation of value-driven strategic sourcing is the lack of instruments that are characterized by analytical rigor and robustness in the identification of strategic sourcing options to achieve strategic goals. Therefore, this research aims to develop a domain-specific modeling technique founded on the Service-Dominant Logic which focuses on the systemic exploration of sourcing alternatives and emphasizes the delivery of value to achieve desired outcomes. This paper reports on a first cycle of Design Science Research which includes the demonstration and the evaluation of the value and utility of the modeling artefacts by means of a case study about IT outsourcing in the healthcare industry

DOMESTIC AND GLOBAL SOURCING

This paper develops a general equilibrium Ricardian model with transaction costs to investigate the determinants of the firm's sourcing decision. It derives conditions under which different sourcing choices and corresponding trade patterns occur in general equilibrium. These conditions suggest that, inter alia, the choice between vertical integration and specialisation depends on the relative internal transaction costs associated with vertical integration and external transaction costs associated with international outsourcing; and that the equilibrium sourcing structures and trade patterns are consistent with a refined theory of comparative advantage that incorporates the effects of transaction costs in international trade.endogenous sourcing decisions, transaction costs, Ricardian model

Global Sourcing

We present a North—South model of international trade in which differentiated products are developed in the North. Sectors are populated by final-good producers who differ in productivity levels. Based on productivity and sectoral characteristics, firms decide whether to integrate into the production of intermediate inputs or outsource them. In either case they have to decide from which country to source the inputs. Final-good producers and their suppliers must make relationship-specific investments, both in an integrated firm and in an arm’s-length relationship. We describe an equilibrium in which firms with diferent productivity levels choose diferent ownership structures and supplier locations, i. e. , they choose different organizational forms. We then study the efects of within-sectoral heterogeneity and variations in industry characteristics on the relative prevalence of these organizational forms. The analysis sheds light on the structure of foreign trade within and across industries.

Determinants of Firm Boundaries: Empirical Analysis of the Japanese Auto Industry from 1984 to 2002

We have assessed the determinants of the choice of integration, relational contracting (keiretsu sourcing) and market sourcing by seven Japanese automobile manufacturers (OEMs) with respect to 54 components in light of contract economics. Our major findings are the following. First, the specificity and interdependency of a component significantly promotes vertical integration over keiretsu and keiretsu over market, consistent with transaction cost economics. Second, interdependency is a more important consideration for the former choice than for the latter choice, and the reverse is the case for specificity. This suggests that the hold-up risk due to specific investment can be often effectively controlled by a relational contracting based on keiretsu sourcing, while accommodating non-contractible design changes may often require vertical integration. Third, while higher testability of a component makes the effects of specificity significantly smaller, it also promotes the choice of keiretsu sourcing over market sourcing. One interpretation of this last result is that while higher testability improves the contractibility of the component with high specificity, it simultaneously enhances the advantage of keiretsu sourcing since it provides more opportunities for the supplier to explore new information for a collaborative exploitation with an OEM.

Sourcing Patterns of Foreign-owned Multinational Subsidiaries in Europe

This paper investigates the determinants of the international input sourcing propensities of foreign-owned multinational subsidiaries in four EU host countries. Major findings concern the impact of subsidiary roles and economic integration on international sourcing patterns. Regional and global integration are leading to a greater import-orientation among MNE subsidiaries, including Product Mandate firms which are assumed to be strongly embedded within host economies. The results cast serious doubts on the effectiveness of traditional criteria for investment attraction; and confirm that stimulating local sourcing is problematic. Specific policy implications are developed relating to the attraction of inward foreign direct investment and to corporate development policies.Multinational enterprises,Subsidiaries, Sourcing, Europe.

Sourcing ethics in the textile sector: The case of C&A

During the last years competition in the textile sector has increased, putting financial returns under considerable pressure. As a result, production has shifted to low wage countries in the third world. This has raised the relevance of ethical procedures. This paper analyses how C&A as one of the largest Western apparel companies organises its sourcing ethics, notwithstanding the financial pressure in the market. Based on interviews with Asian suppliers of C&A during the second half of 2000, we review the opinions of external stakeholders about the sourcing ethics of C&A. Finally, we evaluate C&A’s sourcing ethics from a theoretical perspective.Textile sector; audit; sourcing; code of conduct; compliance; ethics; corporate social responsibility; child labour

Competition and Technological Complexity in Procurement: An Empirical Study of Dual Sourcing

The role of competition in defense procurement has long been controversial due to the extraordinary demand for technological advance, the relatively small production quantities involved and the importance of learning by doing. Since the early 1980s, Defense Department policy has encouraged the use of competition in the production phase of procurement where possible, particularly for relatively simple technologies. Recent theory, however, suggests that splitting production between two bidders ("dual sourcing") produces strong incentives for collusion unless the bidders are unsure of each other's costs, e.g. for sophisticated technologies in the early phases of production. Furthermore, dual sourcing may help discipline contractors in settings where contractual incompleteness is a particular problem. For both these reasons, dual sourcing may be more valuable for complex, rather than simple, technologies. To date, however, there have been no attempts to investigate empirically how technological complexity affects the viability of competition in procurement. I explore the effects of dual sourcing using a panel dataset comprising 14 missile systems with an average of 12.5 years of production history per system. Each missile's complexity is categorized based on the nature of its guidance and control system. Simple missiles enjoy greater scale economies than complex missiles, but the learning curves for the two missile types are not significantly different. The effects of dual sourcing, though, depend importantly on the nature of the technology involved: it significantly speeds learning and interferes with scale economies for complex missiles, but has no significant effects for simple ones. Dual sourcing thus produces no apparent savings for simple missiles, but for the average complex missile dual sourcing lowers unit costs by the seventh year of dual sourcing. Whether these potential savings justify the costs of transferring technology to the second source and the possible weakening of R&D incentives remains an open question.

Capacity Reservation under Spot Market Price Uncertainty

The traditional way of procurement, using long-term contract and capacity reservation, is competing with the escalating global spot market. Considering the variability of the spot prices, the flexibility of combined sourcing can be used to benefit from occasional low short-term spot price levels while the long-term contract is a means to hedge the risk of high spot market price incidents. This contribution focuses on the cost-effective management of the combined use of the above two procurement options. The structure of the optimal combined purchasing policy is complex. In this paper we consider the capacity reservation - base stock policy to provide a simple implementation and comparison to single sourcing options. Our analysis shows that in case of large spot market price variability the combined sourcing is superior over spot market sourcing even in case of low average spot market price and also superior over long-term sourcing even in case of high average spot market price.Capacity reservation; spot market; purchasing policy; supply chain contracts; stochastic inventory control
