In monetary policy, decision makers seek to influence the expectations of agents in ways that can avoid making abrupt, dramatic, and unexpected decisions. Yet in October 1979, Chairman Paul Volcker led the Federal Reserve's Federal Open Market Committee (FOMC) unanimously to shift its course in managing U.S. monetary policy, which in turn eventually brought the era of high inflation to an end. Although some analysts argue that “the presence and influence of one individual”—namely, Volcker—is sufficient to explain the policy shift, this overlooks an important feature of monetary policymaking. FOMC chairmen—however, omnipotent they may appear—do not act alone. They require the agreement of other committee members, and in the 1979 revolution, the decision was unanimous. How, then, did Chairman Volcker manage to bring a previously divided committee to a consensus in October 1979, and moreover, how did he retain the support of the committee throughout the following year in the face of mounting political and economic pressure against the Fed? We use automated content analysis to examine the discourse of the FOMC (with this discourse recorded in the verbatim transcripts of meetings). In applying this methodology, we assess the force of the arguments used by Chairman Volcker and find that deliberation in the FOMC did indeed “matter” both in 1979 and 1980. Specifically, Volcker led his colleagues in coming to understand and apply the idea of credible commitment in U.S. monetary policymaking.

This paper focuses on what has been learned from the past decade of previously unconventional monetary policy measures and the emerging lessons from the effects of monetary policy responses to the Covid shock. The paper explores two observations from recent quantitative easing (QE) policies in detail. First, large QE programmes implemented quickly may be particularly effective in times of market dysfunction. Second, a rapid pace of asset purchases may also enhance QE effectiveness during these periods. These observations suggest a particular form of 'state contingency' for the impact of QE. The paper analyses the potential implications of such state contingency for the appropriate conduct of QE policies and the choice of policy instruments in more normal times. The paper also outlines some potential implications for future central bank balance sheet policies and the operational framework to support them.

The use of hydrajetting for perforating wells has been common since the sixties. During those early years, wells were relatively shallow and jetting success was consistently demonstrated. However, as wells were drilled to depths where rock formations were harder, performance of hydrajetting became less dependable because subsequent stimulation failures occurred more often from the lack of fracture initiation.To help prevent this situation, a series of tests were performed to define new best practices for hydrajet perforating of rock under high ambient pressure. Various rocks were subjected to the tests that were conducted using different jetting pressures and abrasives. To better understand the jetting behavior, the mechanical characteristics (such as Young's Moduli, Poisson's Ratios, and compressive strengths) and chemical structures were also evaluated.This paper discusses various tests results, and new constraints for jetting are defined and presented.
