Intelligent Export Diversification: An Export Recommendation System with Machine Learning
Description: This paper presents a set of collaborative filtering algorithms that produce product recommendations to diversify and optimize a country's export structure in support of sustainable long-term growth. The recommendation system is able to accurately predict the historical trends in export content and structure for high-growth countries, such as China, India, Poland, and Chile, over 20-year spans. As a contemporary case study, the system is applied to Paraguay, to create recommendations for the country's export diversification strategy.

Capital Flow Data – A Guide for Empirical Analysis and Real-time Tracking
Description:
This paper provides an analytical overview of the most widely used capital flow datasets. The paper is written as a guide for academics who embark on empirical research projects and for policymakers who need timely information on capital flow developments to inform their decisions. We address common misconceptions about capital flow data and discuss differences between high-frequency proxies for portfolio flows. In a nowcasting “horse race” we show that high-frequency proxies have significant predictive content for portfolio flows from the balance of payments (BoP). We also construct a new dataset for academic use, consisting of monthly portfolio flows broadly consistent with BoP data.
Starting in 2023, updates to the monthly portfolio flow dataset introduced in this paper are provided as part of the OECD’s Monthly Capital Flow Dataset (De Crescenzio and Lepers 2021), available here: https://www.oecd.org/daf/inv/investment-policy/oecd-monthly-capital-flow-dataset.xlsx

Socio-Economic Spillovers from Special Economic Zones: Evidence from Cambodia
Description: This study examines the socio-economic impact of special economic zones (SEZs) in Cambodia---a prominent place-based policy established in 2005. The paper employs a database on existing and future SEZs in Cambodia with matched household surveys at the district level and documents stylized facts on SEZs in a low-income country setting. To identify causal effects of the SEZ program, the paper (i) constructs an alternative control group including future SEZ program participants and districts adjacent to SEZ hosts; and (ii) employs a propensity score weighting technique. The study finds that entry of SEZs disproportionately benefits female workers and leads to a decline of income inequality at a district level. However, the findings also suggest that land values in SEZ districts tend to rise while wage levels remain largely unchanged relative to other districts. In addition, the paper tests for socio-economic spillovers to surrounding areas and for agglomeration effects associated with clusters of multiple SEZs.

Japan’s Inbound Tourism Boom: Lessons for its Post-COVID-19 Revival
Description: In this paper, we review developments in Japanese inbound tourism and investigate the main determinants of its rapid growth prior to the COVID-19 pandemic. Using a panel autoregressive distributed lag (ARDL) model with data on 34 tourism source markets from 1996Q1 to 2018Q4, we find that not only tourist income and tourism-related relative prices, also visa policies have had significant impacts on Japan’s inbound tourism demand in the long run. In the short run, natural disasters have had large and prolonged effects on tourism. We then derive policy implications for the post-COVID-19 revival of Japanese inbound tourism.

Mitigating Long-term Unemployment in Europe
Description: While unemployment rates in Europe declined after the global financial crisis until 2018/19, the incidence of long-term unemployment, the share of people who have been unemployed for more than one year to the total unemployed, remained high. Moreover, the COVID-19 pandemic could aggravate the long-term unemployment. This paper explores factors associated with long-term unemployment in European countries, using panel of 25 European countries over the period 2000–18. We find that skill mismatches, labor market matching efficiency, and labor market policies are associated with the incidence of long-term unemployment. Among different types of active labor market policies, training and start-up incentives are found to be effective in reducing long-term unemployment.

Tunisia Monetary Policy Since the Arab Spring: The Fall of the Exchange Rate Anchor and Rise of Inflation Targeting
Description: In this paper, we argue that inflation targeting could be the future of Tunisia’s monetary policy. Monetary targeting has proven to be ineffective due to the composition of reserve money, structural liquidity deficit, and higher instability of the money multiplier after 2010. Exchange rate targeting is no longer feasible due to the level of international reserves, current account deficit, and inflation differentials with main trading partners. The Central Bank of Tunisia has already made important progress toward inflation targeting. The paper evidences the existence of increasingly effective interest rate transmission as well as the changing exchange rate passthrough to inflation with the gradual move toward further exchange rate flexibility.

Investor Sentiment, Sovereign Debt Mispricing, and Economic Outcomes
Description: We find that countries which are able to borrow at spreads that seem low given fundamentals (for example because investors take a bullish view on a country's future), are more likely to develop economic difficulties later on. We obtain this result through a two-stage procedure, where a first regression links sovereign spreads to fundamentals, after which residuals from this regression are deployed in a second stage to assess their impact on future outcomes (real GDP growth and the occurrence of fiscal crises). We confirm the relevance of past sovereign debt mispricing in several out-of-sample exercises, where they reduce the RMSE of real GDP growth forecasts by as much as 15 percent. This provides strong support for theories of sentiment affecting the business cycle. Our findings also suggest that countries shouldn't solely rely on spread levels when determining their fiscal strategy; underlying fundamentals should inform policy as well, since historical relationships between spreads and fundamentals often continue to apply in the medium-to-long run.

Stress Testing and Calibration of Macroprudential Policy Tools
Description: We present a semi-structural model of default risk, which is a function of loan and borrower characteristics, economic conditions, and the regulatory environment. We use this model to simulate bank credit losses for stress-testing purposes and to calibrate borrower-based macroprudential tools. The proposed approach is very flexible and is particularly useful when there is limited history of crisis episodes, when crises bring unanticipated shocks where past tail events offer little guidance and when structural shocks or changes in financial regulations have altered the loan default process. We apply the model to quantify mortgage lending risk in two distinct mortgage markets. For each application, we show a range of modeling adjustments that can be made to capture country-specific institutional features. The model uses bank portfolio data broken down by risk bucket and vintage, which enables us to take explicit account of the loan life cycle and to incorporate the housing and economic cycles. This feature facilitates a timely assessment of banks’ loss-absorbing capacity and the buildup of systemic risk conditional on policy. It also enables counterfactual analysis and the evaluation of macroprudential policy interventions.

Measuring Income Inequality and Implications for Economic Transmission Channels
Description: We study the channels that theoretically transmit the effects of inequality to economic growth, unlike much of the existing literature that focuses on the direct linkage. The role of inequality in these transmission channels is difficult to pin down and varies with the particular inequality indicator chosen. We run our analyses with six methodologically distinct inequality measures (Gini coefficients and Top10 income shares). Methodological differences within the set of Gini coefficients and the Top10 income shares exert a first-order impact on the estimated relationships, which is generally larger than the effect of switching between Gini and Top10 income shares. For a given inequality indicator, we find that the transmission channels can react in opposite directions, with the net effect on growth difficult to determine. Finally, we emphasize two additional but so far underappreciated empirical complications: (i) estimated relationships change over time; and (ii) fragile countries create significant but counterintuitive empirical associations that may obscure structural relationships.

Trade, Productivity and (Mis)allocation
Description: We examine the gains from globalization in the presence of firm heterogeneity and potential resource misallocation. We show theoretically that without distortions, bilateral and export liberalizations increase aggregate welfare and productivity, while import liberalization has ambiguous effects. Resource misallocation can either amplify, dampen or reverse the gains from trade. Using model-consistent measures and unique new data on 14 European countries and 20 industries in 1998-2011, we empirically establish that exogenous shocks to export demand and import competition both generate large aggregate productivity gains. Guided by theory, we provide evidence consistent with these effects operating through reallocations across firms in the presence of distortions: (i) Both export and import expansion increase average firm productivity, but the former also shifts activity towards more productive firms, while the latter acts in reverse; (ii) Both export and import exposure raise the productivity threshold for survival, but this cut-off is not a sufficient statistic for aggregate productivity; (iii) Efficient institutions, factor and product markets amplify the gains from import competition but dampen those from export access.
