Productivity and Product Markets in Korea: Evidence from Advanced Economies
Description: This paper constructs an industry-level dataset of productivity across advanced economies, showing that Korea’s labor productivity and total factor productivity levels are below the median of other advanced economies. We identify sizable industry-level productivity gaps in Korea with respect to the global frontier, especially in market-oriented services. Using the OECD’s Product Market Regulation (PMR) Indicators, we show that tighter PMRs slow industry-level productivity growth, and these effects occur across all areas of PMRs—state control, barriers to entrepreneurship, and barriers to trade and investment—and through several detailed indicators. These effects are transmitted through higher product prices and unit labor costs of industries exposed to regulation. The results confirm the potential for Korea to boost overall productivity and growth through PMR reforms, especially by lowering barriers in service and network sectors, reducing restrictions applying to trade and investment, and evaluating the scope of government involvement in the economy.

Biases in Survey Inflation Expectations: Evidence from the Euro Area
Description: This paper documents five facts about inflation expectations in the euro area. First, individual inflation forecasts overreact to individual news. Second, the cross-section average of individual forecasts of inflation underreact to shocks initially, but overreacts in the medium term. Third, disagreement about future inflation increases in response to news when the current inflation is high, and declines when inflation is low, consistent with a zero lower bound of expectations. Fourth, overreaction of individual inflation forecasts to news increased after the global financial crisis (GFC). Fifth, the reaction of average expectations (and of actual inflation) to shocks became more muted post-GFC in the euro area, but not in the U.S.

Updating Inflation Weights in the UK and Germany during COVID-19
Description: The COVID-19 pandemic altered consumption patterns significantly in a short period of time. However, official inflation statistics take time to reflect these changes in the weights of the CPI consumption basket. Using credit card data for the UK and Germany, we document how consumption patterns changed and we quantify the resulting inflation bias. We find that consumers experienced a higher level of inflation at the beginning of the pandemic than what a fixed-weight inflation (or the official-weight) index suggests and a lower inflation thereafter. We also show that weights can differ among age groups as well as between in-person and online spenders. These differences affect the purchasing power of the population heterogeneously. We conclude that CPI inflation indexes based on frequently updated weights can provide useful inputs to assess changes in the cost of living and, if shifts in consumption patterns prove persistent, determine the need to introduce new official weights and inform monetary policy.

The Propensity to Remit: Macro and Micro Factors Driving Remittances to Central America and the Caribbean
Description: In contrast to expectations, remittances to Central America and the Caribbean (CAC) surprised positively during 2020 and 2021. This study revisits the key macro indicators driving remittances, looks at the heterogeneous impacts of the global financial crisis (GFC) and COVID shocks, then uses micro data from the U.S. Current Population Census to examine individual features of immigrant households and how this might affect the “propensity to remit”. The paper finds that remittance flows are responsive to both sending and receiving country economic conditions and that labor market conditions are particularly important determinants of remittance flows, explaining the unexpected jump in remittance flows in 2020-2021 and providing stronger predictive power when combined with income variables. Analysis of the micro data reinforces these findings, reflecting the existence of a family resource sharing model at play.

Did Insurers Become Risk-Loving During “Low-for-Long”? The Role of Returns, Ratings, and Regulation
Description: European life insurance companies are important bond investors and had traditionally played a stabilizing role in financial markets by pursuing “buy-and-hold” investment strategies. However, since the onset of the ultra-low interest rates era in 2008, observers noted a decline in the credit quality of insurers’ bond portfolios. The commonly-held explanation for this deterioration is that low returns pushed insurers to become more risk-taking. We argue that other factors—such as surging rating downgrades, bond revaluations, and regulatory changes—also played a key role. We estimate that rating changes, revaluations, and search for yield each account for about one-third each of the total deterioration in credit quality. This result has important policy implications as it reestablishes the view that insurers’ investment behavior tends to be passive through the cycle—rather than risk-seeking.

Unpacking Impact of COVID-19 on Vietnamese Firms: Evidence from a Novel Survey
Description: Using a unique representative panel survey of Vietnamese enterprises in 2020, we find that the pandemic and associated government support package had a heterogenous impact across firms. The government support package, particularly tax cuts and deferrals, helped alleviate short term stress, but tight ineligibility criteria and cumbersome procedures impacted take-up. Econometric analysis suggests that the likelihood of accessing support was associated with firm size, with larger firms more likely to receive support compared to smaller firms, even after controlling for sector, firm ownership and financial health. Credit support was effective in alleviating liquidity constraints and allaying firm pessimism only for large firms. Interestingly, firms experiencing sales losses and those with lower pre-crisis productivity were more likely to resort to digitalization, suggesting that the pandemic could help narrow productivity gaps.

Cross-Country Evidence on the Revenue Impact of Tax Reforms
Description: Many countries face the challenge of raising additional tax revenues without hurting economic growth. Comprehensive, cross-country information on the revenue impact of tax policy changes can thus support informed decision-making on viable reforms. We assess the likely revenue impact of various tax policy changes based on a sample of 21 advanced and emerging market economies, using granular information from the IMF Tax Policy Reform Database v.4.0. Our findings suggest that the revenue yield of a tax policy change varies significantly depending on the tax instrument adopted (e.g., VAT or personal income tax) and the nature of the change (i.e., rate, base). For example, in our sample, base-broadening changes to personal and corporate income taxes as well as to excise and property taxes have generally a more significant and long-lasting revenue yields than rate changes. By contrast, rate changes appear to have a relatively more significant revenue impact in the case of VAT and social security contributions. We also observe an asymmetry in the revenue impact of most tax policy measures when controlling for the direction of tax changes (i.e., its significance varies depending on whether taxes are increased or decreased). While our results are based on qualitative information of tax policy changes (i.e., dummy variables), the revenue yields of rate measures are not materially different from those that would be obtained using quantitative information on the size of the change.

Regional Disparities in Europe
Description: While the level of disparities across regions in 10 advanced European economies studied in this paper mostly reflects productivity gaps, the increase since the Great Recession has resulted from diverging unemployment rates. Following the pandemic, this could be further exacerbated given teleworkability rates are lower in poorer regions than in high-income regions, making them ex-ante more vulnerable to the pandemic’s likely material impact on the prevalence of remote work. Preliminary evidence from 2020 confirms that regional disparities between countries increased during 2020. A further concern is that the pandemic might accelerate the automation of jobs across Europe, something which often happens following recessions. While lagging regions have lower ex-ante vulnerabilities against the routinization, the transformation of jobs through sectors with higher routinization rates in these regions could increase their vulnerability to technological change over time. The green transition could also lead to challenges for regions that have benefitted from carbon-intensive growth strategies. Finally, the paper discusses the role for policies—including placed-based ones—in reducing disparities in the face of the aforementioned short, medium, and long-term risks.

Experimental Indicators of Digital Industries in Select Countries: Definitions, Methods, and Results
Description: The pervasive impact of digitalization on the economy and the lack of an agreed definition makes it challenging to obtain estimates of the digital economy. Nowadays, some countries have estimated the value of the digital economy by identifying digital products or industries as defined in the international classifications. This study presents the estimates of digital industries for five countries that participated in an experimental exercise, applying a simplified standard approach recommended by the international agencies as part of the national accounts framework and using publicly available and limited secondary information. The results show that the structure and evolution of digital industries vary across countries and over time and that the estimates depend significantly on the underlying data sources. The conclusions of this exercise reveal the need to upgrade the data sources to better identify the impact of digitalization and contribute to policy-making on the economic benefits of digitalization.

A Tale of Tier 3 Cities
Description: This paper provides new estimates of the housing stock, construction rates and price developments by city tier in China in order to understand where imbalances might be concentrated, and the implications of any significant contraction. We also update estimates of the size of China’s rapidly evolving real estate sector through 2021, allowing one to look at the initial impact of COVID-19, as well as extending the analysis to incorporate urban-expansion related infrastructure construction. We argue that China overall faces imbalances between supply and demand for housing stock, but the problem is significantly deeper outside tier 1 cities.
