Abstract The solution concept of iterated strict dominance for static games with complete information recursively deletes choices that are inferior. Here, we devise such an algorithm for the more general case of incomplete information. The ensuing solution concept of generalized iterated strict dominance is characterized in terms of common belief in rationality as well as in terms of best response sets. Besides, we provide doxastic conditions that are necessary and sufficient for modelling complete information from a one-person perspective.

We study a local interaction model where agents play a finiten-person game following a perturbed best-response process with inertia. We consider the concept of minimalp-best response set to analyze distributions of actions on the long run. We distinguish between two assumptions made by agents about the matching rule. We show that only actions contained in the minimalp-best response set can be selected provided thatpis sufficiently small. We demonstrate that these predictions are sensitive to the assumptions about the matching rule.

Earlier chapters of this book found that the Hobbesian hypothesis is false; the Lockean proviso is unfulfilled; contemporary states and property rights systems fail to meet the standard that social contract and natural property rights theories require for their justification. This chapter assesses the implications of those findings for the two theories. Section 1 argues that, whether contractarians accept or reject these findings, they need to clarify their argument to remove equivocation. Section 2 invites efforts to refute this book’s empirical findings. Section 3 discusses a response open only to property rights theorists: concede this book’s empirical findings and blame government failure. Section 4 considers the argument that this book misidentifies the state of nature. Section 5 considers a “bracketing strategy,” which admits that observed stateless societies fit the definition of the state of nature, but argues that they are not the relevant forms of statelessness today. Section 6 discusses the implications of accepting both the truth and relevance of the book’s findings, concluding that the best response is to fulfil the Lockean proviso by taking action to improve the lives of disadvantaged people.

We present the case of a Japanese man in his 60s with duodenal neuroendocrine carcinoma with distant metastases. Chemotherapy with irinotecan plus cisplatin was initiated as a first-line regimen. However, disease progression was observed after only two cycles. Therefore, amrubicin was administered as a second-line chemotherapy. The patient showed a long-term effect of amrubicin therapy, and the best response was a partial response after seven cycles. For duodenal neuroendocrine carcinoma, amrubicin therapy can be considered an effective treatment option as salvage chemotherapy.
