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.

Covered Interest Parity Deviations: Macrofinancial Determinants
Description: For about three decades until the Global Financial Crisis (GFC), Covered Interest Parity (CIP) appeared to hold quite closely—even as a broad macroeconomic relationship applying to daily or weekly data. Not only have CIP deviations significantly increased since the GFC, but potential macrofinancial drivers of the variation in CIP deviations have also become significant. The variation in CIP deviations seems to be associated with multiple factors, not only regulatory changes. Most of these do not display a uniform importance across currency pairs and time, and some are associated with possible temporary considerations (such as asynchronous monetary policy cycles).

Corporate Tax Reform: From Income to Cash Flow Taxes
Description: This paper uses a multi-region, forward-looking, DSGE model to estimate the macroeconomic impact of a tax reform that replaces a corporate income tax (CIT) with a destination-based cash-flow tax (DBCFT). Two key channels are at play. The first channel is the shift from an income tax to a cash-flow tax. This channel induces the corporate sector to invest more, boosting long-run potential output, GDP and consumption, but crowding out consumption in the short run as households save to build up the capital stock. The second channel is the shift from a taxable base that comprises domestic and foreign revenues, to one where only domestic revenues enter. This leads to an appreciation of the currency to offset the competitiveness boost afforded by the tax and maintain domestic investment-saving equilibrium. The paper demonstrates that spillover effects from the tax reform are positive in the long run as other countries’ exports benefit from additional investment in the country undertaking the reform and other countries’ domestic demand benefits from improved terms of trade. The paper also shows that there are substantial benefits when all countries undertake the reform. Finally, the paper demonstrates that in the presence of financial frictions, corporate debt declines under the tax reform as firms are no longer able to deduct interest expenses from their profits. In this case, the tax shifting results in an increase in the corporate risk premia, a near-term decline in output, and a smaller long-run increase in GDP.

The Present Value of Corporate Profits: A Forecasters' Survey Perspective
Description: This paper presents and discusses the estimates of the present value of corporate profits in the United States from 1984 to 2018. To value the expected income stream, it uses the long-range forecasts of professional forecasters for pre-tax corporate earnings and long-term Treasury note yields, sourced from the Blue Chip Economic Indicators survey. The appraised value of corporate earnings can point in real time at periods where market prices are deviating from valuations implied by expected earnings and interest rates. Market participants' forecasts seem to interpret most of the earnings fluctuations as permanent, underestimating the cyclical fluctuations The over-reaction to transitory shocks and changes in long-term outlook leads to swings in the valuation, in line with swings in the observed market prices.
