Deglobalisation: risk or reality?

Globalisation is supposedly on the retreat. There is a common perception that firms are diversifying supply chains and moving production closer to home. So, are we heading towards deglobalisation? The ECB Blog takes a closer look and finds that the data tell a different story.

      Abstract
      The Global Financial Crisis established that policymakers should consider the stage of the financial cycle to better evaluate the cyclical position of the economy when designing monetary policy decisions. If financial variables are omitted from the estimations of the output gap, a common and unobserved indicator of the business cycle, important financial or external imbalances that may lead to future recessions may not be captured. This paper presents a suite of estimates of output gaps incorporating financial variables. The estimates are based both on small unobserved components models and a large unobserved components model that follows a production function approach. The results show that exploiting the information content of financial variables, which co-move strongly with the output cycle, can sometimes improve output gap estimates. However, these improvements are of a limited magnitude and very sensitive to the choice of the chosen financial variables.

      Abstract
      Regulation to control carbon emissions challenges firms to develop optimal carbon management policies. We set out a unified approach to study the trade-offs carbon pricing poses for firms and how they should therefore best respond. Our model shows that while carbon pricing curtails firms’ carbon emissions, polluting firms tilt their green investment mix towards more immediate yet short-lived options – such as solely reducing emissions (abatement) instead of investing in green innovation – as it becomes costlier to comply. Under emissions trading systems, larger balances of carbon credits dampen firms’ efforts to reduce their carbon emissions. Our analysis reveals that carbon regulation does not necessarily reduce shareholder value if firms are sufficiently committed to reducing their carbon footprint.

      Abstract
      Inflation affects the purchasing power of households. This paper documents large, idiosyncratic inflation differences between households in their everyday shopping. Low-income households have experienced higher inflation in the last ten years, but the difference to richer households has been small and time varying. Household-specific behaviour appears to dominate inflation differences within countries. Between countries, multinational retail chains not only differentiate products by branding, but also charge different prices for identical products. Retailers continue to differentiate prices along national borders, even within largely integrated economic regions. Price changes, however, are broadly aligned across borders within the same retailers.

      Abstract
      The coronavirus (COVID-19) pandemic caused a deep recession globally, as well as in the euro area, accompanied by a steep decline in inflation rates in 2020. This paper reviews some of the main challenges created by the pandemic for inflation measurement and provides micro price data analysis of how price setting has reacted to the strong COVID-19 shock. For this purpose, we use three different, but complementary, microdata sources for specific countries and sectors: micro price data underlying the official consumer price indices in Germany, Italy, Latvia and Slovakia; (scanner) data from German and Italian supermarkets; and online (web-scraped) prices for Poland. A common finding of the micro price studies in this paper is that state dependence significantly contributed to the price-setting response to the COVID-19 shock. Nevertheless, the extent and degree of responses varies widely by sector and even country, also depending on the severity of the pandemic situation.

      Abstract
      This paper provides an extensive literature review and analyses some open issues in the measurement of inflation that can only be explored in depth using micro price data. It builds on the analysis done in the context of the ECB’s strategy review, which pointed at directions for improvement of the Harmonised Index of Consumer Prices (HICP), including better quantification of potential biases. Two such biases are the substitution bias and the quality adjustment bias. Most analyses of substitution bias rest on the concept of the cost of living, positing that preferences are stable, homogeneous and homothetic. Consumer behaviour is characterised by preference shifts and heterogeneity, which influence the measurement of the cost of living and substitution bias. Climate change may make the impact of preference shifts particularly relevant as it causes the introduction of new varieties of “green” goods and services (zero-kilometre food, sustainable tourism) and a shift from “brown” to “green” products. Furthermore, PRISMA data show that consumption baskets and thus inflation vary across income classes (e.g. higher-income households tend to buy more expensive goods), pointing to non-homotheticity of preferences. When preferences are heterogeneous and/or non-homothetic, it is important to monitor different experiences of inflation across classes of consumers/citizens. This is particularly important when very large relative price changes affect items that enter the consumption baskets of the rich and the poor, the young and the old, in very different proportions. Another open area of analysis concerns the impact of quality adjustment on measured inflation. Evidence based on web-scraped prices shows that the various implicit quality adjustment methods can produce widely varying inflation trends when product churn is fast. In the euro area specifically, using different quality adjustment methods can be an overlooked source of divergent inflation trends in sub-categories, and, if pervasive, shows up in overall measured inflation divergence across countries.

      Abstract
      This paper discusses the normative implications of the micro evidence on heterogeneity in price setting gathered by the Price-setting Microdata Analysis Network (PRISMA) for the level of inflation that central banks should target. The micro price data underlying the consumer price index are used to estimate relative price trends over the product life cycle. Minimising the welfare consequences of relative price distortions in the presence of these trends requires targeting a significantly positive inflation rate in France, Germany and Italy: the steady-state inflation rate, jointly maximising welfare in all three countries, ranges from 1.1% to 1.7%. Other considerations not taken into account in the present paper may push up optimal inflation targets further. The welfare costs of targeting an inflation rate of zero, as suggested by monetary models ignoring relative price trends, or of targeting 4%, turn out to be substantial.

      Abstract
      This paper analyses the implications of the evidence on micro price setting gathered by Price-setting Microdata Analysis Network (PRISMA) for inflation dynamics and monetary policy, relying on calibrated models and direct empirical evidence. According to models calibrated to the euro area micro evidence in Gautier et al. (2022, 2023), infrequent price changes and moderate state dependence in price setting should result in a meaningful Phillips curve in the euro area. Empirical estimates of the Phillips curve during the low-inflation period confirm previous findings of a relatively flat but stable slope. This estimated flat slope reflects both infrequent and subdued price adjustment in response to aggregate shocks, i.e. the presence of nominal and real rigidities. Model-based simulations show that, due to non-linearities in price setting, changes in trend inflation above 5-6% would have significant effects on the euro area Phillips curve. Similarly, shocks to nominal costs larger than 15% would result in non-linear effects on inflation dynamics in calibrated models. In line with these simulations, recent micro evidence suggests that the return of higher and more volatile inflation seems to be associated with higher frequencies of price changes, mainly because the frequency of price increases rises with the level and volatility of inflation.

      Abstract
      E-commerce has become more prevalent throughout Europe in the last decade. The coronavirus (COVID-19) pandemic accelerated this trend, particularly in the retail sector. This paper focuses on the implications of increasing business-to-consumer e-commerce for prices and inflation in the euro area. It highlights three key results. First, whether online prices and inflation are higher or lower than their offline counterparts depends on the distribution model, the sector and the country. Moreover, properly selected online prices track official inflation indices even in real time. Second, the effect of e-commerce on inflation appears to be transient and differs between countries. However, as the penetration of some markets is still low, these transitory effects will likely persist at the euro area level for several years. Third, online prices change more frequently than offline prices. This might lead to greater price flexibility overall as online trade gains market share in a growing number of sectors.

      Abstract
      This paper documents five stylised facts relating to price adjustment in the euro area, using various micro price datasets collected in a period with relatively low and stable inflation. First, price changes are infrequent in the core sectors. On average, 12% of consumer prices change each month, falling to 8.5% when sales prices are excluded. The frequency of producer price adjustment is greater (25%), reflecting that the prices of intermediate goods and energy are more flexible. For both consumer and producer prices, cross-sectoral heterogeneity is more pronounced than cross-country heterogeneity. Second, price changes tend to be large and heterogeneous. For consumer prices, the typical absolute price change is about 10%, and the distribution of price changes shows a broad dispersion. For producer prices, the typical absolute price change is smaller, but nevertheless larger than inflation. Third, price setting is mildly state-dependent: the probability of price adjustment rises with the size of price misalignment, mainly reflecting idiosyncratic shocks, but it does not increase very sharply. Fourth, for both consumer and producer prices, the repricing rate showed no trend in the period 2005-19 but was more volatile in the short run. Fifth, small cyclical variations in frequency did not contribute much to fluctuations in aggregate inflation, which instead mainly reflected shifts in the average size of price changes. Consistent with idiosyncratic shocks as the main driver of price changes, aggregate disturbances affected inflation by shifting the relative number of firms increasing or decreasing their prices, rather than the size of price increases and decreases.

      Abstract
      We examine the link between labour market developments and new technologies such as artificial intelligence (AI) and software in 16 European countries over the period 2011-2019. Using data for occupations at the 3-digit level in Europe, we find that on average employment shares have increased in occupations more exposed to AI. This is particularly the case for occupations with a relatively higher proportion of younger and skilled workers. This evidence is in line with the Skill Biased Technological Change theory. While there exists heterogeneity across countries, only very few countries show a decline in employment shares of occupations more exposed to AI-enabled automation. Country heterogeneity for this result seems to be linked to the pace of technology diffusion and education, but also to the level of product market regulation (competition) and employment protection laws. In contrast to the findings for employment, we find little evidence for a relationship between wages and potential exposures to new technologies.

      Abstract
      Density forecasts of euro area inflation are a fundamental input for a medium-term oriented central bank, such as the European Central Bank (ECB). We show that a quantile regression forest, capturing a general non-linear relationship between euro area (headline and core) inflation and a large set of determinants, is competitive with state-of-the-art linear benchmarks and judgemental survey forecasts. The median forecasts of the quantile regression forest are very collinear with the ECB point inflation forecasts, displaying similar deviations from “linearity”. Given that the ECB modelling toolbox is overwhelmingly linear, this finding suggests that the expert judgement embedded in the ECB forecast may be characterized by some mild non-linearity.

      Abstract
      Life insurers sell savings contracts with surrender options, which allow policyholders to prematurely receive guaranteed surrender values. These surrender options move toward the money when interest rates rise. Hence, higher interest rates raise surrender rates, as we document empirically by exploiting plausibly exogenous variation in monetary policy. Using a calibrated model, we then estimate that surrender options would force insurers to sell up to 2% of their investments during an enduring interest rate rise of 25 bps per year. We show that these fire sales are fueled by surrender value guarantees and insurers’ long-term investments.

      Abstract
      Based on a non-linear equilibrium model of the banking sector with an occasionally-binding equity issuance constraint, we show that the economic impact of changes in bank capital requirements depends on the state of the macro-financial environment. In ”normal” states where banks do not face problems to retain enough profits to satisfy higher capital requirements, the impact on bank loan supply works through a ”pricing channel” which is small: around 0.1% less loans for a 1pp increase in capital requirements. In ”bad” states where banks are not able to come up with sufficient equity to satisfy capital requirements, the impact on loan supply works through a ”quantity channel”, which acts like a financial accelerator and can be very large: up to 10% more loans for a capital requirement release of 1pp. Compared to existing DSGE models with a banking sector, which usually feature a constant lending response of around 1%, our state-dependent impact is an order of magnitude lower in ”normal” states and an order of magnitude higher in ”bad” states. Our results provide a theoretical justification for building up a positive countercyclical capital buffer in ”normal” macro-financial environments.
