I derive a rigorous method to help determine whether a true parameter takes a value between two arbitrarily chosen points for a given level of confidence via a multiple testing procedure which strongly controls the familywise error rate. For any test size, the distance between the upper and lower bounds can be made smaller than that created by a confidence interval. The procedure is more powerful than other multiple testing methods that test the same hypothesis. This test can be used to provide an affirmative answer about the existence of a negligible effect. 相似文献

Edith Penrose's The Theory of the Growth of the Firm proposed a process theory of growth based on the pursuit of knowledge by the firm and unconstrained by government. In her subsequent studies of foreign direct investment by large firms in developing countries, Penrose considers the firm and government as actors in the same growth process. This paper explores the development of Penrose's expanded process theory of growth from 1955 to 1973 in which she assumes that neither dual actors nor foreign expansion requires a new or special theory. This finding has implications for the resource-based view and the eclectic ownership–location–internationalisation paradigm interpretations of international business. 相似文献

There is a lot of creative potential lying dormant in corporations because too many managers fail to see innovation as a process to be deliberately managed. C. Joshua Abend sees innovation connected to virtually everything that happens—or doesn't happen—in an organization. He offers in this article ideas that managers can use to remove the impediments to increased innovation and productivity. 相似文献

The persistence properties of economic time series have been a primary object of investigation in a variety of guises since the early days of econometrics. Recently, work on nonlinear modelling for time series has introduced the idea that persistence of a shock at a point in time may vary depending on the state of the process at that point in time. This article suggests investigating the persistence of processes conditioning on their history as a tool that may aid parametric nonlinear modelling. In particular, we suggest that examining the nonparametrically estimated derivatives of the conditional expectation of a variable with respect to its lag(s) may be a useful indicator of the variation in persistence with respect to its past history. We discuss in detail the implementation of the measure and present a Monte Carlo investigation. We further apply the persistence analysis to real exchange rates. 相似文献

This note applies an evolutionary analysis to Skaperdas's (1992) static model of conflict and cooperation, in which agents are faced with trade‐offs between joint production and share competition. We adopt the stochastic evolution approach, and assume that each agent occasionally mimics the action of the winner of the stage. In contrast to Skaperdas's results that justify full or partial cooperation in productive activity, the long‐run equilibrium must exhibit total conflict; nobody engages in production at all. 相似文献

Summary. Bertrand criticized Cournot's analysis of the competitive process, arguing that firms should be seen as playing a strategy
of setting price below competitors' prices (henceforth, the Bertrand strategy) instead of a strategy of accepting the price needed to sell an optimal quantity (the Cournot strategy). We characterize Nash equilibria in a generalized model in which firms choose among Cournot and Bertrand strategies. Best responses always exist in this model. For the duopoly case, we show that iterated best responses
converge under mild assumptions on initial states either to Cournot equilibrium or to an equilibrium in which only one firm
plays the Bertrand strategy with price equal to marginal cost and that firm has zero sales.

This paper reports an experiment investigating how assignments improve economic efficiency in a modified version of the standard voluntary-contributions mechanism. The experiment uses a non-binding message that makes common information assignments in the repeated game. A credible assignment is one actually followed by the participants. It turns out to be difficult to credibly assign the symmetric efficient outcome in four person cohorts, but we did discover one assignment that was credible in the last match of the evolutionary repeated game. 相似文献
