For those countries or industries in which a rise in (measured) market power actually translates into an effective restriction of competition and increasing profits, as it seems to be the case for the US, a significant slowdown of investment, business dynamism, fall in labour share and wages has been observed. The latter in turn has several policy implications, from obvious considerations of reduced consumers' welfare, to low productivity growth, to severe implications for the transmission mechanism of monetary policy. However, one has to question the nature of such an increase in market power. If the latter stems from “good” market forces in which industries experience a reallocation of economic activities towards the largest and most productive firms, as some research shows, a debate opens up on the necessary reform of competition policies.

The major scholarly editions of Shakespeare published from the mid twentieth century through to the opening decades of the current century are considered in this chapter. Peter Alexander's edition for the Glasgow publishers Collins is tracked in detail and its use as the working text for the BBC Shakespeare TV series is registered. The Riverside edition, which served for many years as the dominant text for the US university market, is also considered. The history of the Oxford Shakespeare, in its various incarnations from its first appearance in 1986, is mapped. The Oxford edition provided the base text for the Norton Shakespeare, though, in more recent times, Norton has severed the link and established its own text. The history of the Norton edition is considered, as is the Royal Shakespeare Company endorsed edition, produced by Macmillan. The chapter ends with an exploration of significant challenges to New Bibliographic editorial practice that emerged in the closing decades of the twentieth century, often driven by poststructuralist thinking; it is noted that, despite these challenges, editors continue to find the basic techniques of the New Bibliography of considerable utility.

We describe the structure of the model, built plugging the entry/exit decisions into a macroeconomic system, by using a notion of statistical distribution of expectations that is consistent with the idea of rational expectations (at least in its original formulation) to model the entry decision of potential entrants. The theoretical framework is also useful to analyze, on a theoretical ground, the behavior of the firms’ markups over the cycle and is employed for the agent-based simulations. In particular, we model a macroeconomic system with oligopoly, entry/exit, and heterogeneous individuals. The algebraic framework of a new macro-model is analytically dissected, to prepare a sound basis for the experiments in simulation.
