We study how consumer preferences affect the transmission of microeconomic price shocks to consumer price index (CPI) inflation. These preferences give rise to complementarities and substitutions between goods, generating demand-driven cross-price dependencies that either amplify or mitigate the impact of price shocks. Our results demonstrate that while both effects are present, positive spillovers due to complementarities dominate. The magnitude of these cross-price effects is significant, demonstrating their importance in shaping CPI inflation dynamics. Most importantly, demand-driven price linkages decisively shape the impact of producer prices on CPI inflation. These findings underscore the need to take into account demand-driven price dependencies when assessing the impact of price shocks on CPI inflation, rather than relying solely on supply-related ones.

The pandemic caused expenditure shares to vary more than usual, leading to serious ramifications when combined with the fact that the expenditure shares used to calculate CPI inflation are 1-2 years old. This caused a potential bias in the measurement of inflation. We also look at the cost-of-living crisis and found that the lags in updating the expenditure shares for energy and food led to an underestimate of inflation in 2022. Inflation also has a large effect on the measurement of the public sector deficit. With a high debt-GDP ratio and high inflation, there was a substantial inflation tax.

Since early 2021, food prices in Britain have increased by 30%. Using monthly microdata, researchers have found that frictions in the UK’s new trade relationship with the European Union (EU) play an important part in this inflation. The trade relationship is evolving, with further changes expected in 2024. This article establishes a framework for identifying trade-related inflation in close to real time. Using programming techniques, we collect daily prices of over 100,000 supermarket items, covering 80% of the UK grocery market. We identify 1,200 products from 12 countries with a protected designation of origin (PDO). This allows us to link price changes to individual EU economies. Addressing the predominance of EU PDOs, we employ a large language model to discern product origins from additional web-scraped data, thus broadening our analysis to cover over 67,000 products. Since August 2023, we find that prices for EU-originating food products have increased at a rate of 50% higher than domestically sourced products. This study presents a unique methodological approach to dissecting food sector inflation, which is well-positioned to be used in a policy setting, allowing us to assess the possible impact of impending nontariff barriers at the GB-EU border in 2024.

This article analyses the correlates of public confidence in the Bank of England (BoE) both at the aggregate and individual levels to answer the following two questions: What are the correlates of trust in the BoE? Is the inflation surge associated with a structural shift in attitudes towards the BoE? Data from the BoE’s Inflation Attitudes survey (2001–2023) suggest that although inflation performance and public trust seem associated at the aggregate level, at the individual level this correlation is weaker. Further analyses suggest some changes in the correlates of public confidence since the inflation surge.

We study the effects of professionals’ survey-based inflation expectations on inflation for a large number of 36 economies, using dynamic cross-country panel estimation of New-Keynesian Phillips curves. We find that inflation expectations have a significantly positive effect on inflation. We also find that the effect of inflation expectations on inflation is significantly larger when inflation is higher. This suggests that second-round effects via the effects of higher inflation expectations on inflation are more relevant in a high-inflation environment.

In a series of academic publications, Edward Nelson has contended that from the 1950s until the late 1970s, UK policymakers failed to recognise the primacy of monetary policy in controlling inflation. He argues that the highwater mark of monetary policy neglect occurred in the 1970s. This thesis has been rejected by Duncan Needham who has explored several experiments with monetary policy from the late 1960s and challenged the assertion that the authorities neglected monetary policy during the 1970s. Drawing on evidence from the archives and other sources, this article documents how the UK authorities wrestled with monetary policy following the 1967 devaluation of sterling. Excessive broad money growth during the early 1970s was followed by the highest level of peacetime inflation by 1975. The article shows that despite the experiments with monetary policy, a nonmonetary view of inflation dominated the mindset of policymakers during the first half of the 1970s. In the second half of the 1970s there was a change in emphasis and monetary policy became more prominent in economic policymaking, particularly when money supply targets were introduced. Despite this, the nonmonetary view of inflation dominated the decision processes of policymakers during the 1970s.

This paper develops a monetary R&D-driven endogenous growth model featuring endogenous innovation scales and the price-marginal cost markup. To endogenize the step size of quality improvement, we propose a tradeoff mechanism between the risk of innovation failure and the benefit of innovation success in R&D firms. Several findings emerge from the analysis. First, a rise in the nominal interest rate decreases economic growth; however, its relationship with social welfare is ambiguous. Second, either strengthening patent protection or raising the professional knowledge of R&D firms leads to an ambiguous effect on economic growth. Third, the Friedman rule of a zero nominal interest rate fails to be optimal in view of the social welfare maximum. Finally, our numerical analysis indicates that the extent of patent protection and the level of an R&D firm’s professional knowledge play a crucial role in determining the optimal interest rate.

This paper identifies several ways in which “measurement matters” in detecting quantity-theoretic linkages between money growth and inflation in recent data from the Euro Area, United Kingdom, and USA. Elaborating on the “Barnett critique,” it uses Divisia aggregates in place of their simple-sum counterparts to gauge the effects that monetary expansion or contraction is having on inflationary pressures. It also uses one-sided time series filtering techniques to track, in real time, slowly shifting trends in velocity and real economic growth that would otherwise weaken the statistical money growth-inflation relationship. Finally, it documents how measures of inflation based on GDP were distorted severely, especially in the EA and UK, during the 2020 economic closures. Using measures based on consumption instead, estimates from the P-star model confirm that changes in money growth have strong predictive power for subsequent movements in inflation.

The 1922 Rand Rebellion was the only instance of worker protest in the twentieth century in which a modern state used tanks and military airplanes, as well as mounted infantry, to suppress striking workers. These circumstances were unprecedented in their own time and for most of the century. The compressed and intensely violent rebellion of twenty thousand white mineworkers in South Africa’s gold mines had several overlapping features. Within a matter of days—from 6 to 12 March—it went from a general strike to a racial pogrom and insurrection against the government of Prime Minister Jan Smuts. Throughout all these twists and turns, the battle standard remained, “Workers of the world unite and fight for a White South Africa!” Race and violence were integral features of South Africa’s industrial history, but they do not explain the moments when discrete groups of people chose to use them as weapons or bargaining tools. At the close of the First World War, for instance, South Africa’s white mine workers demanded a more comprehensive distribution of the privileges of white supremacy, but in a manner that was both violent and contentious. Consequently, South Africa’s immediate postwar period became one of the most violent moments in its history.
