This article critically examines the pertinent issues in ex ante and ex post moral hazard in healthcare markets, with the U.S. Affordable Care Act (ACA) as its focal point of inquiry. First, it compares the various types of information asymmetries resulting from the production, allocation, and utilization of health insurance. Second, it reviews the literature on adverse selection, moral hazard, and risk mitigation against which salient ACA reforms are analyzed. In contrasting conventional moral hazard from an alternative theory of welfare maximization, it suggests that healthcare (over)utilization cannot necessarily be considered wasteful, even if it ends up costing insurers more on a short-term basis. Costs and savings attributable to healthcare spending under the ACA will vary between the consumer, insurer, and regulator-subsidizer. Despite the ambiguities surrounding definitions of “health,” the challenge of containing inefficient moral hazard, and encouraging its desirable counterpart, lies in the tradeoffs that arise between consumer access to affordable and quality healthcare and the market competitiveness of health insurers. The new Trump administration will have to address these tradeoffs in repealing and replacing the ACA, particularly in light of escalating insurance premiums and deductibles, narrower provider networks, and technical implementation issues. 相似文献

This paper investigates the employment effects of foreign acquisitions in acquired firms in Swedish manufacturing during the 1990s; a period characterized by a dramatic increase in foreign ownership. We find some evidence of positive employment effects in acquired firms and it seems that the employment of skilled labor increases more than that of less-skilled labor. Our results indicate that the positive employment effects are more pronounced in acquired non-MNEs than in Swedish MNEs. Furthermore, we observe shifts in skill intensities toward higher shares of skilled labor in non-MNEs taken over by foreign MNEs, but not in acquired Swedish MNEs. 相似文献

We consider an economic model that features (1) a continuum of agents and (2) an aggregate state of the world over which agents have an infinitesimal influence. We first review the connections between the ??eductive?? viewpoint on expectational stability and standard game-theoretical rationalizability concepts. The ??eductive?? reasoning selects different plausible beliefs that are a priori, and possibly a posteriori, ??diverse??. Such beliefs are associated with the sets of ??Cobweb tatonnement?? outcomes, ??Rationalizable States?? and ??Point-Rationalizable States?? (the latter two being shown to be convex). In the case where our model displays strategic complementarities, unsurprisingly, all our ??eductive?? criteria support similar conclusions, particularly when the equilibrium is unique. With strategic substitutabilities, the success of expectational coordination, in the case where a unique equilibrium does exists, relates with the absence of cycles of order 2 of the ??Cobweb?? mapping: in this case, full expectational coordination would be achieved. However, when cycles of order 2 do exist, our different criteria predict larger sets of outcomes, although all tied with cycles. Under differentiability assumptions, the Poincaré?CHopf method leads to other global stability results. At the local level, the different criteria under scrutiny can be adapted. They lead to the same expectational stability conclusions, only when there are local strategic complementarities or strategic substitutabilities. However, for the local stability analysis, it is demonstrated that the stochastic character of expectations can most often be forgotten. 相似文献

Information from 175 superstores, operated by three companies, is used to investigate the importance of store operator in setting superstore employment levels and types of employment. Store operator is shown to be a significant factor determining employment numbers and types in British superstores. 相似文献

Abstract. In the literature on the welfare effects of free trade under imperfect competition, one important case seems to have been overlooked, and that is the Bertrand duopoly model with differentiated products. Although many authors have analysed the welfare effects of free trade under Cournot duopoly and demonstrated the possibility of losses from trade, there has been no thorough analysis of the welfare effects of free trade under Bertrand duopoly. In this article we present a thorough analysis of the welfare effects of free trade under Bertrand duopoly with differentiated products, and it is shown that there are always gains from trade.

Why would potentially intolerant majorities in a democracy protect the rights of unpopular groups? This paper models the formation of legal standards that determine the extent of civil liberty in a society. It is shown that tolerant legal standards emerge over time, despite all individuals having intolerant preferences. Each period citizens choose activities that have social consequences. A majority vote determines which of these activities are legally protected. Because of errors in interpreting the symbolic content of these activities, voters from the majority will not impose excessively intolerant standards, otherwise they may end up severely punishing members of their own group by mistake.
Extending this framework to a dynamic model, we examine Markovian equilibria of the game when government improves with time in its ability to correctly interpret citizens' activities. These improvements allow an unchanging majority to impose increasingly intolerant standards over time. It is shown that societies with high political turnover due to population changes are apt to choose tolerant legal standards. Societies with low turnover are more apt to choose more intolerant and unstable ones. Each group seeks to prevent auditing capabilities of government from improving too much over time in order to prevent future majorities from successfully enforcing more intolerant standards. 相似文献

How do individuals' spatial decisions affect the institutions for public goods provision over time? This paper describes a dynamic model in which the provision mechanism for a public project is itself the object of locational choice of individuals. Individuals in an ongoing society must choose between a location with a Majority Rule mechanism and one with a Voluntary Contribution mechanism. Each mechanism determines a funding decision for a local public project which is repeated over time. Generations of individuals asynchronously supercede their ‘parents’, creating an entry/exit process that allows individuals with possibly different beliefs to enter society. A self-confirming equilibrium (SCE) belief process describes an evolution of beliefs in this society consistent with a self-confirming equilibrium (Fudenberg and Levine, 1993) of the repeated location/provision game. It is shown that the process with belief mutation as new individuals enter society results in a globally absorbing state in which the Majority Rule mechanism is the unique survivor of the two. 相似文献
