TL;DR: A review of the market efficiency literature can be found in this article, where the authors discuss the work that they find most interesting, and offer their views on what we have learned from the research on market efficiency.
Abstract: SEQUELS ARE RARELY AS good as the originals, so I approach this review of the market efficiency literature with trepidation. The task is thornier than it was 20 years ago, when work on efficiency was rather new. The literature is now so large that a full review is impossible, and is not attempted here. Instead, I discuss the work that I find most interesting, and I offer my views on what we have learned from the research on market efficiency.
TL;DR: The shadow price approach to the estimation and decomposition of economic efficiency was proposed in this paper, which incorporated exogenous influences on efficiency change and productivity change, and the estimation of technical efficiency was discussed.

TL;DR: In this article, the authors focus on the way in which the operation of the medical-care industry and the efficacy with which it satisfies the needs of society differ from a norm, and the most obvious distinguishing characteristics of an individual's demand for medical services is that it is not steady in origin as, for example, for food or clothing but is irregular and unpredictable.
Abstract: Publisher Summary This chapter focuses on the way in which the operation of the medical-care industry and the efficacy with which it satisfies the needs of society differ from a norm. The term norm that the economist usually uses for the purposes of such comparisons is the operation of a competitive model, that is, the flows of services that would be offered and purchased and the prices that would be paid for them. The interest in the competitive model stems partly from its presumed descriptive power and partly from its implications for economic efficiency. If a competitive equilibrium exists at all and if all commodities relevant to costs or utilities are in fact priced in the market, then the equilibrium is necessarily optimal. There is no other allocation of resources to services that will make all participants in the market better off. The most obvious distinguishing characteristics of an individual's demand for medical services is that it is not steady in origin as, for example, for food or clothing but is irregular and unpredictable. Medical services, apart from preventive services, afford satisfaction only in the event of illness, a departure from the normal state of affairs.
TL;DR: Ebsco as discussed by the authors examined empirical evidence on allocative efficiency in economics and compared it with X-efficiency, an unindentified type of efficiency which has motivation as its major element.
Abstract: Examines empirical evidence on allocative efficiency in economics. Comparison of the merit of allocative efficiency with X-efficiency, an unindentified type of efficiency which has motivation as its major element; Analysis of the magnitude and nature of X-efficiency; View that firms and economies do not operate on an outer-bound possibility surface consistent with their resources.
