Using US quarterly data (1967–2023), including inflation’s post-pandemic surge and decline alongside monetary policies characterized by quantitative easing before refocusing on the 2% target, we utilize traditional and novel econometric tools to assess the stability of key macroeconomic variables’ responses to monetary shocks. Our findings confirm the relevance of a broad Divisia aggregate in understanding monetary policy transmission and highlight its empirical importance in explaining output and price dynamics across decades. Time-varying impulse response functions (IRFs) reveal consistent and puzzle-free price responses to Divisia-based monetary shocks throughout the sample, aligning with theory. Time-varying IRFs indicate that pandemic-related outliers in GDP (2020Q2) do not disrupt results. In contrast, Fed Funds rate or shadow policy interest rate shocks often yield puzzling outcomes across earlier and extended periods.

I investigate the welfare maximizing steady-state inflation rate in a heterogeneous-agent New Keynesian model with Downward Nominal Wage Rigidity (DNWR). After matching the annual wage change distribution in the U.S., I demonstrate that DNWR has a significant impact on the economy, particularly when the inflation target is set low. The optimal inflation rate is estimated to be as high as 8.8%, and increasing the inflation target to the optimal level yields a welfare gain of nearly 3.50%. While the results exhibit sensitivity to parameterization, a broad range of calibrations indicates that the optimal inflation rate is consistently above 3%.

This paper adds to the literature on global inflation synchronization by distinguishing the traded and non-traded content of the consumption basket. Using a novel database of monthly CPI series of 40 countries from 2000, a dynamic factor model with stochastic volatility decomposes inflation into global, income-group, and idiosyncratic components. While synchronization has historically been prominent in tradable goods inflation, findings also reveal an increasing synchronization in non-tradable inflation. Second, I use a time-varying parameter vector autoregressive model to investigate the potential spillover effect. The results provide evidence of spillover from tradable to non-tradable inflation, while the reverse is mainly muted over the sample. Finally, results from local projections indicate that a tightening of US monetary policy causes a significant decline in global headline inflation, which is primarily driven by the heightened sensitivity of tradable goods.

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 1920–1 recession did not transpire entirely without federal intervention, as commonly believed. Following lending by several Federal Reserve banks, the federally chartered War Finance Corporation (WFC) lent to support exports and shortly after the recession, it lent aggressively to assist banks in agricultural regions, as numerous bank suspensions resulted from the agricultural depression of the early 1920s. Bank suspensions decreased markedly in 1922 to the lowest annual total during the 1921–33 period. This article assesses the impact of WFC lending on bank suspensions, and to what extent the WFC's provision of liquidity helped to resolve the existing difficulties.

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.

We examine the role of fragmentation of information in explaining the dynamics of sectoral inflation. Using the quarterly survey of firms’ prices and costs in Japan, we first document two empirical facts: the sensitivity of sectoral inflation to changes in sectoral costs monotonically decreases with the dispersion of changes in (i) current costs and (ii) those in the past. A direct application of the dispersed information model can reconcile the fact (i) but fails to reconcile the fact (ii). We then extend the standard imperfect information model to construct a dynamic general equilibrium model that features fragmentation of information, wherein a finite number of groups of firms exist and firms in the same group share common idiosyncratic noises in their signals. Using this model, we find that the degree of fragmentation of information plays a crucial role in explaining these empirical facts.

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.

We provide empirical evidence that the impact of quantitative easing (QE) programs on investment is weaker for countries with high-credit market regulations. We then extend a simple DSGE model with segmented financial markets to include credit regulation and examine its impact on the transmission of conventional and unconventional monetary policies. In our model, the government requires banks to hold a fraction of their assets in government debt. We show that the presence of such regulation can invert monetary transmission under QE policy: An expansionary QE program raises term premiums on corporate bonds and causes a contraction instead of an expansion in the economy. Such a perversion is absent under conventional policy. Further, in contrast to Carlstrom et al. (2017), we show that a simple Taylor rule welfare dominates a term premium peg under financial shocks, while the peg does better in the case of non-financial shocks.

Post the great financial crisis (GFC) of 2008–2009, there has been a surge in the macroeconomics literature on aggregate uncertainty. Although the recent literature has recognized the adverse real effects of global uncertainty shocks in emerging market economies (EMEs), the role of monetary policy in offsetting these adverse effects and their link with the exchange rates is not explored in the literature. We find that the currently followed interest rate rules (IRRs) under a flexible inflation-targeting regime are ineffective in stabilizing the domestic economy during periods of high global uncertainty in the EMEs. Using a small open economy new Keynesian DSGE model with Epstein–Zin preferences and second-moment demand shocks, we compare and propose alternate monetary policy rules that significantly reduce welfare losses. We find that the best monetary policy rule in terms of welfare depends on the nature of shock that is, first-moment or second-moment shock.

Brexit has cast a long shadow over the UK economy, with its impact masked by the COVID-19 pandemic and the crisis in Ukraine. Disentangling those effects is not straightforward, but that is the aim of the papers contained in this Special Issue. This Special Issue draws upon excellent contributions from some leading academic and policy-oriented researchers, all expert in the macroeconomic impacts of Brexit.

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.

We analyze financial literacy regarding interest rates, inflation, and risk diversification in nine Eastern European countries based on survey data collected in the fall 2022. The percentage of individuals with an understanding of all three concepts is generally low but varies strongly among countries, from 13 percent in Romania to 47 percent in the Czech Republic. Financial illiteracy is particularly acute among those with primary or lower secondary education. Among the three concepts, inflation is what people know best in eight out of nine countries – a pattern which has emerged recently and is in contrast to other countries, where interest rate literacy is highest. Differences in lifetime inflation experience, in particular experience of high or hyperinflation, affect inflation literacy. Higher financial literacy is associated with a higher propensity to save and a lower propensity to be financially vulnerable in six out of nine countries.

The present study discusses the current wage situation in India and the need for living wages as workers and employees grapple with the cost of living crisis. A case study of two districts of Madhya Pradesh (MP) state is presented to demonstrate how the living wage benchmarks based on the Anker Methodology compare with existing minimum wage fixations and other development indicators. The living wage benchmarking is based on field surveys conducted in Ratlam and Chhindwara districts in October–December 2021, and a rigorous analysis of nationally representative consumption and expenditure surveys conducted by the National Sample Survey Organisation and the Centre for Monitoring Indian Economy. Our living wage estimates are 1.8 times the minimum wages for agricultural labourers and 43% more than those earned by non-agricultural unskilled labourers. Moreover, the actual wages reported are less than half of the estimated living wages, indicating that the current incomes and wages for workers and farmers of rural MP are far from adequate to lead a decent life.

The title of this article is a riff off a publication of G. C. Harcourt’s 1974 piece, ‘The social consequences of inflation’. He wrote this in a period of the global economy that bears some strong similarities to our own contemporary phase when inflation is suddenly back in the global headlines. There is at least one significant difference: at that time, Harcourt highlighted inflation as the outcome of an excess of total demand in real terms over available supplies of goods and services when the potential workforces and existing stocks of capital goods were fully employed. Current inflationary pressures, by contrast, arise from the combination of specific sectoral supply bottlenecks, rising profit margins in oligopolistic global markets for food and fuel and financial speculation in these markets.

Spearheaded by the International Monetary Fund (IMF), there has been a rethinking of macroeconomic policies, in particular with regard to targeting inflation at a very low level in the wake of 2008–2009 global economic crisis. We provide a content analysis of the IMF Staff Reports on Article IV consultation of 12 Asian developing countries during the period 2009–2010 in order to see whether that rethinking has been reflected in the IMF’s advice. The findings of this study reveal that the IMF continues with its prescription of achieving low inflationary environment irrespective of country-specific circumstances.

This paper critically examines the key empirical evidence used to support the fiscal consolidation argument, complemented by a brief assessment of the limitations of the analytical foundation of the growth promoting benefits of the fiscal consolidation thesis. It also reviews the evidence on the debt-growth relationship at some length. It finds that the negative relationship between debt and GDP growth is influenced by outliers or exceptionally high debt-GDP ratios. It also points out that the composition of public debt matters. Additionally, the debt-GDP relationship appears to be non-linear—positive first and turning to negative, but there is considerable variation in the estimated turning or ‘tipping’ point, which is not helpful as a policy guide. Historical evidence does not lend support to the concerns that the current situation is likely to cause rapid upward spiraling of public indebtedness. Finally, the argument that fiscal consolidation is possible without adversely affecting growth is not based on robust empirical evidence. This conclusion is reinforced by a succinct overview of some country-specific experiences (Denmark, Ireland and United States).

Inflation rates and their convergence within Euro area have been a major concern, since well before the advent of the single currency. Inflation differentials are a normal phenomenon in any monetary union and even in long-established monetary unions. The aim of this research is to examine the main factors of inflation differentials in the Euro-zone for the period 1999–2018. Our empirical estimates appear to suggest that a one-percentage-point increase in the positive output gap typically leads to an increase of about 20 basis points in the inflation rate of EMU countries. We also find three structural breaks, in 2004, 2008 and in 2010. Since the monetary policy of the European Central Bank is geared at maintaining low and stable inflation, the productivity growth should be increased, and the real effective exchange rates should be decreased and become more homogeneous among EMU. Therefore, countries’ inflation differentials may become less persistent.

We assess the effects of financial shocks on inflation, and to what extent financial shocks can account for the “missing disinflation” during the Great Recession. We apply a Bayesian vector autoregressive model to US data and identify financial shocks through a combination of narrative and short-run sign restrictions. Our main finding is that contractionary financial shocks temporarily increase inflation. This result withstands a large battery of robustness checks. Negative financial shocks help therefore to explain why inflation did not drop more sharply in the aftermath of the financial crisis. Our analysis suggests that higher borrowing costs after negative financial shocks can account for the modest decrease in inflation after the financial crisis. A policy implication is that financial shocks act as supply-type shocks, moving output and inflation in opposite directions, thereby worsening the trade-off for a central bank with a dual mandate.

This paper constructs a two-period general equilibrium model with the effective lower bound of nominal interest rates and describes price competition among monopolistically competitive firms as a coordination game. While the model has multiple equilibria with different levels of inflation (positive or zero), the equilibrium selection in line with global games implies that the economy with high expected productivity growth moves into the positive inflation equilibrium. The policy analyses indicate that monetary policy measures such as an increase in the target inflation can prevent the economy from moving into the zero inflation equilibrium even with low productivity growth.
