Abstract Optimal policy rules—including those regarding income taxation, commodity taxation, public goods, and externalities—are typically derived in models with homogeneous preferences. This article reconsiders many central results for the case in which preferences for commodities, public goods, and externalities are heterogeneous. When preference differences are observable, standard second-best results in basic settings are unaffected, except those for the optimal income tax. Optimal levels of income taxation may be higher, the same, or lower on types who derive more utility from various goods, depending on the nature of preference differences and the concavity of the social welfare function. When preference differences are unobservable, all policy rules may change. The determinants of even the direction of optimal rule adjustments are many and subtle.

AbstractThis study offers a conceptual analysis of the social economy in China within the context of institutional transition. In China, economic reform has engendered significant social changes. Accelerated economic growth, privatization of the social welfare system, and the rise of civil society explain the institutional contexts in which a range of not-for-profit initiatives, neither state-owned nor capital-driven, re-emerged. They are defined in this research as the social economy in China. This study shows that although the term itself is quite new, the social economy is no new phenomenon in China, as its various elements have a rich historical tradition. Moreover, the impact of the transition on the upsurge of the Chinese social economy is felt not only through direct means of de-nationalization and marketization and, as a consequence, the privatization of China's social welfare system, but also through various indirect means. The development of the social economy in China was greatly influenced by the framework set by political institutions and, accordingly, legal enabling environments. In addition, the link to the West, as well as local historical and cultural traditions, contribute towards explaining its re-emergence. Examining the practices in the field shows that the social economy sector in China is conducive to achieving a plural economy and an inclusive society, particularly by way of poverty reduction, social service provision, work integration, and community development. Therefore, in contemporary China, it serves as a key sector for improving welfare, encouraging participation, and consolidating solidarity.

This chapter describes and compares the two most important policy-analysis methodologies in economics: cost-benefit analysis (CBA) and the social-welfare-function (SWF) framework. Both approaches are consequentialist and welfarist; both are typically combined with a preference-based view of well-being. Despite these similarities, the two methodologies differ in significant ways. CBA translates well-being impacts into monetary equivalents, and ranks outcomes according to the sum total of monetary equivalents. By contrast, the SWF framework relies upon an interpersonally comparable measure of well-being. Each possible outcome is mapped onto a list (vector) of these well-being numbers, one for each person in the population; the ranking of outcomes, then, is driven by some rule (the SWF) for ranking these well-being vectors. The utilitarian SWF and the prioritarian family of SWFs (each corresponding to well-developed positions in moral philosophy) are especially plausible. The case for using CBA rather than one of these SWFs is weak—or so the chapter argues.

This article proposes comparing nonprofit news organizations that prioritize social welfare goals with the hybrid organizational form that mixes the institutional logics of charities and business enterprises: the Social Enterprise. The institutional logic comprises organizing templates, patterns of actions and values. These Social News Enterprises (SNEs) are analyzed as hybrids mixing the institutional logics of commercial, public, and alternative news media. Financed by donations and the revenue from services, SNEs engage in public, investigative, and explanatory journalism. Normative behavioral principles of SNEs are used to compare the impact-based model of ProPublica with the growth-focused model of The Texas Tribune.
