Product development with multiple partners: Strategies and conflicts in networks

This paper provides an insight into and discusses the variety of sources of conflict in linking multiple partners in a network to the product development process. Conflict issues are discussed in relation to focal company strategies for product development within networks. On the basis of three case studies representing three different strategic intentions and network situations, our findings suggest that the sources of conflict are related to the actors' definition and negotiation of the development task at hand. The study suggests that the ability to combine and find complementarities in the strategic intentions of the multiple participating actors is essential to accomplish innovation. The paper concludes that influential actors initiating or acceding to changes are crucial for reaching a positive outcome in joint product development.

Specialization or diversification? The situation and transition of households’ livelihood in agricultural heritage systems

Zhagana Agriculture-Forest-Animal Husbandry Composite System (ZCS) is the first Globally Important Agricultural Heritage Systems site in the Tibetan Plateau. Similar to many traditional agricultural regions, with the development of tourism and leisure agriculture, the peasant households in ZCS have gradually changed their livelihood strategies and livelihood activities in the past 10 years, resulting in the disappearance of some traditional farming methods and agricultural landscapes with a long history. By taking livelihood assets as the entry point and livelihood strategies as the core, this paper analyzed the basic situation of households’ livelihood and the transition mechanism of different livelihood strategies in order to offer suggestions for the dynamic conservation and sustainable development of Agricultural Heritage Systems (AHS). (1) The livelihood strategies of peasant households in ZCS can be divided into two major categories: specialized strategies and diversified strategies. (2) According to the empirical calculation of the livelihood asset accounting framework of AHS, the average livelihood asset value of peasant households in ZCS is 2.040, showing that the situation of peasant households’ livelihood is inadequate. (3) The transition of peasant households’ livelihood strategies from traditional strategy to specialized or diversified livelihood strategies is mainly influenced by natural assets, human assets, cultural assets, social assets and informational assets. In order to meet the growing material and spiritual needs of peasant households and achieve the sustainable development of ZCS simultaneously, it is suggested that the agriculture-forestry-animal husbandry-tourism composite strategies shall be taken as the development direction of peasant households’ livelihood strategies.     

The welfare effect of income tax deductions for losses as insurance: Insured- versus insurer-sided adverse selection

Kaplow (1992) shows in a complete-information environment that allowing income tax deductions for losses as partial insurance is undesirable in the presence of private insurance markets. This paper elaborates on Kaplow's finding by studying two extreme types of asymmetric information structures in private insurance markets: Either the insured or insurers possess superior information. It is shown that our derived result is consistent with Kaplow's if the insured have superior information; however, Kaplow's negative conclusion with respect to the income tax deduction will be overturned if insurers have superior information instead. A policy implication from our finding is that whether or not to allow an income tax deduction for losses needs to be more refined and, specifically, it should be tailored to the “adverse selection” information structures of private insurance.
