Importing Inputs for Climate Change Mitigation: The Case of Agricultural Productivity
Description: This paper estimates agricultural total factor productivity (TFP) in 162 countries between 1991 and 2015 and aims to understand sources of cross-country variations in agricultural TFP levels and its growth rates. Two factors affecting agricultural TFP are analyzed in detail – imported intermediate inputs and climate. We first show that these two factors are independently important in explaining agricultural TFP – imported inputs raise agricultural TFP; and higher temperatures and rainfall shortages impede TFP growth, particularly in low-income countries (LICs). We also provide a new evidence that, within LICs, those with a higher import component of intermediate inputs seem to be more shielded from the negative impacts of weather shocks.

Nonresident Capital Flows and Volatility: Evidence from Malaysia’s Local Currency Bond Market
Description: Malaysia’s local currency debt market is one of the most liquid public debt markets in the world. In recent years, the growing share of nonresident holders of debt has been a source of concern for policymakers as a reason behind exchange rate volatility. The paper provides an overview of the recent developments in the conventional debt market. It builds an empirical two-stage model to estimate the main drivers of debt capital flows to Malaysia. Finally, it uses a GARCH model to test the hypothesis that nonresident flows are behind the observed exchange rate volatility. The results suggest that the public debt market in Malaysia responds adequately to both pull and push factors and find no firm evidence that nonresident flows cause volatility in the onshore foreign exchange market.

Reform Options for Mature Defined Benefit Pension Plans: The Case of the Netherlands
Description: The Netherlands has been operating fully funded, defined benefit second pillar pension schemes that have consistently ranked high worldwide for delivering high replacement rates while featuring strong solidarity among members. Yet the long-term sustainability of the Dutch pension funds has been undermined in recent years by protracted low interest rates and unfavorable demographic developments, exacerbating controversies over intergenerational transfer mechanisms within the plans. This has prompted a national debate over ways to move toward more individualization while preserving financial security at retirement for all. This paper draws on this experience, illustrated by stress testing simulations and assessed vis-à-vis solutions implemented in peer countries, to discuss the main policy trade-offs associated with the reform of mature pension systems in advanced economies.

Commodity Terms of Trade: A New Database
Description: This paper presents a comprehensive database of country-specific commodity price indices for 182 economies covering the period 1962-2018. For each country, the change in the international price of up to 45 individual commodities is weighted using commodity-level trade data. The database includes a commodity terms-of-trade index—which proxies the windfall gains and losses of income associated with changes in world prices—as well as additional country-specific series, including commodity export and import price indices. We provide indices that are constructed using, alternatively, fixed weights (based on average trade flows over several decades) and time-varying weights (which can account for time variation in the mix of commodities traded and the overall importance of commodities in economic activity). The paper also discusses the dynamics of commodity terms of trade across country groups and their influence on key macroeconomic aggregates.

Inequality in Good and Bad Times: A Cross-Country Approach
Description: This paper provides evidence of a strong relationship between the short-term dynamics of growth and inequality in developing economies. We find that reductions in inequality during growth upswings are largely reversed during growth slowdowns. Using a new methodology (mediation analysis), we identify unemployment, and youth unemployment especially, as the main channel through which fluctuations in growth affect future dynamics in inequality. These findings suggest that both the quality of jobs created and labor market policies are important to ensure that growth outcomes are conducive to inequality reduction.

Financial Dollarization of Households and Firms: Does It Differ?
Description: Using a newly complied and extended database from International Financial Statistics, and applying different panel-regression techniques, this paper documents the evolution of households’ and firms’ dollarization over the past decade. We assess the macroeconomic determinants of dollarization for households and firms and explore differences between high and low-income countries. We find that households’ and firms’ dollarization in loans and deposits are weakly explained by the currency substitution model, except in low income countries, where inflation plays a significant role. Instead, market development variables such as financial deepening, access to external debt and FX finance as well as other market considerations are key to explain the dynamics of deposits and loans dollarization, regardless of the level of income.These factors can account for a significant fraction of the dollarization, but using a variance decomposition model, there is evidence that a non-negligible portion has yet to be explained. This suggests that there are key determinants for household and firm dollarization that are not fully captured by traditional macroeconomic explanatory variables.

Global Value Chains: What are the Benefits and Why Do Countries Participate?
Description: Over the last two decades, world trade and production have become increasingly organized around global value chains (GVC). Recent theoretical work has shown that countries can benefit from participation in GVCs through multiple channels. However, little is known empirically about the economic importance of supply chains. We use the Eora MRIO database to compute different measures of GVC participation for 189 countries and illustrate global patterns of supply chains as well as their evolution over time in order to contribute to this topic. We find that GVC-related trade, rather than conventional trade, has a positive impact on income per capita and productivity, however there is large heterogeneity and the gains appear more signifcant for upper-middle and high-income countries. We document that “moving up” to more high-tech sectors while participating in major supply chains does take place but is not universal, suggesting other factors matter. We confirm the findings of the standard gravity literature for GVC trade; highlighting the key role of institutional features such as contract enforcement and the quality of infrastructure as determinants of GVC participation.

Innovation and Corporate Cash Holdings in the Era of Globalization
Description: We document a broad-based trend in rising cash holdings of firms across major industrialized countries over the last two decades, a trend that is most pronounced for firms engaged strongly in R&D activities. Our contributions to the literature are twofold. First, we develop a simple model that brings together the insights from modern trade theory (Melitz, 2003) with those of contract theory in corporate finance (Holmström and Tirole, 1998) to show that increased openness to trade can result in rising returns to innovation and in turn greater demand for cash as firms insure against innovation-induced liquidity risk. Second, we derive sharp empirical predictions and find supporting evidence for them using firm-level data across major G7 countries during 1995-2014, a period that saw an unprecedented rise in globalization and business innovation.

China’s Digital Economy: Opportunities and Risks
Description: China’s digital economy has expanded rapidly in recent years. While average digitalization of the economy remains lower than in advanced economies, digitalization is already high in certain regions and sectors, in particular e-commerce and fintech, and costal regions. Such transformation has boosted productivity growth, with varying impact on employment across sectors. Going forward, digitalization will continue to reshape the Chinese economy by improving efficiency, softening though not reversing, the downward trend of potential growth as the economy matures. The government should play a vital role in maximizing the benefits of digitalization while minimizing related risks, such as potential labor disruption, privacy infringement, emerging oligopolies, and financial risks.

Gross National Happiness and Macroeconomic Indicators in the Kingdom of Bhutan
Description: This paper examines the origins and use of the concept of Gross National Happiness (or subjective well-being) in the Kingdom of Bhutan, and the relationship between measured well-being and macroeconomic indicators. While there are only a few national surveys of Gross National Happiness in Bhutan, the concept has been used to guide public policymaking for the country’s various Five-Year Plans. Consistent with the Easterlin Paradox, available evidence indicates that Bhutan’s rapid increase in national income is only weakly associated with increases in measured levels of well-being. It will be important for Bhutan to undertake more frequent Gross National Happiness surveys and evaluations, to better build evidence for comovement of well-being and macroeconomic concepts such as real national income.
