Who Pays the Bill? Distributional and Fiscal Consequences of Elevated Inflation in Thailand
Description: This paper analyzes the distributional impacts of inflation in Thailand. For that aim, the paper uses rich micro-survey data on 46,000 Thai households to study the effect of the recent elevated inflation on poverty, its distributional effects on different income levels, and the fiscal cost to compensate households from real income losses. To study the multidimensional impact of inflation, the paper also studies how inflation differentially affects households through the consumption, income, and wealth channel. The analysis shows that under a baseline scenario, poverty in Thailand could increase by 1.3 percentage points—about 900,000 people—in the absence of government intervention. Targeted fiscal support to only compensate households that are below the national poverty line from rising inflation amount to 0.05 percent of GDP. However, fiscal support to compensate relatively rich households, defined as those above the median of the income distribution, amount to 1.4 percent of GDP. Moreover, due to high levels of debt, richer households benefit from inflation relative to poorer households. Finally, the paper also delves into policy responses undertaken by the Thai government and Asian and emerging economies to mitigate elevated inflation.

Geopolitics and International Trade: The Democracy Advantage
Description: Do political regimes determine how geopolitics influence international trade? This paper provides an empirical answer to the question by analyzing the joint impact of democracy and geopolitical distance between countries with an augmented gravity model of bilateral trade flows and an extensive dataset of more than 4 million observations on 59,049 country-pairs over the period 1948–2018. Implementing the Poisson Pseudo-Maximum Likelihood regression and the two-stage least squares with instrumental variable approach, I find that geopolitical developments are not as important as income and geographical distance in determining bilateral trade flows and that democracy fosters international trade and moderates the potential negative impact of geopolitics. While the impact of democracy and its interaction with geopolitical distance are significant across all countries, the magnitude of these effects is substantially larger in advanced economies than in developing countries, reflecting the greater strength of democratic institutions, on average, in advanced economies.

Is Schumpeter Right? Fintech and Economic Growth
Description: The rise of fintech is revolutionizing the financial landscape, with products and companies advancing innovative technologies to improve and automate financial services. In this paper, I use a novel dataset and implement a dynamic modelling to investigate the relationship between fintech and economic growth in a panel of 198 countries over the period 2012–2020. This cross-country approach—utilizing direct measures of fintech and dealing with potential endogeneity—provides interesting empirical insights. First, the impact magnitude and statistical significance of fintech on real GDP per capita growth depend on the type of instrument (digital lending vs. digital capital raising). While digital lending has a statistically significant positive effect on economic growth, digital capital raising has a large but insignificant effect. Second, the overall impact of fintech including all instruments is positive and statistically significant because of the overwhelming share of digital lending in total. Finally, while the positive relationship between fintech and growth is stronger in magnitude in advanced economies, the statistical significance of this effect is higher in developing countries. Taken as a whole, these results confirm Schumpeter’s prediction that financial innovation can promote growth, but not every type of fintech becomes an accelerator.

ASAP: A Conceptual Model for Digital Asset Platforms
Description: This working paper inaugurates the "Technology Fundamentals for Digital Finance" series, concentrating on the technical aspects of financial Digital Assets. The series aims to facilitate the use of a clear terminology in a nascent platform-oriented paradigm of financial infrastructures, by laying the groundwork for technical discussions on digital asset standards. The paper introduces a conceptual model named ASAP (Access, Service, Asset, Platform) for Digital Asset Platforms (DAP), leveraging insights from IT industry practices and experiments by central banks. The ASAP model is illustrated through examples and use cases of tokenized assets, to demonstrate the possible usage and merits of modeling Digital Asset Platforms with four layers. Just as the utilization of a seven-layer model (often refered to as TCP/IP) has been fundamental to the interoperability of the internet, it is anticipated that the four-layer ASAP model for Digital Asset Platforms will similarly promote cross-platform interoperability, including across various jurisdictions, paving the way for a more cohesive digital asset ecosystem.

In Search of the Origin of Original Sin Dissipation
Description: In this paper, we examine how, contrary to the ‘original sin’ hypothesis, emerging market economies have gained the ability to borrow abroad in their local currency. We empirically analyze the relationship of various economic variables with local currency debt and identify three crucial conditions for the capacity to borrow in local currency: institutional quality, sufficient depth in the domestic bond market, and adequate performance in inflation targeting. While shares in JPMorgan Government Bond Index-Emerging Markets (GBI-EM) index also appear to be influential, the associations with local currency debt is less clear. We conduct a similar empirical analysis on portfolio equity, which represents a safer form of external liability than foreign currency debt, and verify that the depth of the equity market plays a key role in attracting foreign capital to domestic equity markets. Finally, we propose a simple portfolio model based on the inelastic market hypothesis to explain the positive correlation between capital market depth and the dissipation of original sin, which refers to the presence of more external liability in the form of equity or local currency debt. In essence, our analysis suggests that emerging market economies with reasonably strong fundamentals are not necessarily reliant on foreign currency debt.

Does FinTech Increase Bank Risk Taking?
Description: Motivated by its rapid growth, this paper investigates how FinTech activities influence risk taking by financial intermediaries (FIs). In this context, this paper revisits an ongoing debate on the impact of competition on financial stability: on one side, it is argued that greater competition encourages greater risk taking (competition-fragility hypothesis), while the other side of the debate asserts that more competition can increase financial stability (competition-stability hypothesis). Using a curated databased covering over 10,000 FIs and global FinTech activities, we find a robust relationship whereby greater FinTech presence is associated with heightened risk taking by FIs, offering support for the competition-fragility hypothesis. However, the inclusion of bank-, industry-, and country-specific characteristics can alter this relationship. Importantly, there is suggestive evidence indicating that in certain cases, greater FinTech presence may be associated with less FI risk taking amid stronger domestic institutions. Notwithstanding the relevance for policy, this paper presents a novel framework that may help reconcile some of the conflicting results in the literature which have found supportive evidence for each of the two competing hypotheses.

The Leisure Gains from International Trade
Description: The average number of hours worked has been declining in many countries. This can be explained if workers have preferences with income effects outweighing substitution effects. Then, an optimal response to rising income is to reduce labor supply to enjoy more leisure. In this paper, I develop a novel structural link between trade and aggregate labor supply. Using a multi-country Ricardian trade model, I show that reducing trade barriers leads to fewer hours worked while being compatible with an increase in welfare. In addition, I derive an hours-to-trade elasticity and estimate it by exploiting exogenous income variation generated by aggregate trade. On average, I quantify that the rise in trade openness between 1950 and 2014 explains 7 percent of the total decline in hours per worker in high-income countries.

Fueling or Following Growth? Causal Effects of Capital Inflows on Recipient Economies
Description: Identifying the causal impact of capital inflows on growth and development has been a perennial challenge. This paper proposes a new way to investigate the effect of capital flows on recipient emerging and developing economies, using shift-share instruments and correcting for indirect flows. It finds a significantly beneficial effect of loan and bond inflows on economic performance, which materializes after a few years. It also finds some confirmation that the absorptive capacity of recipient economies depends on their fundamentals.

U.S. Monetary Policy Spillovers to Middle East and Central Asia: Shocks, Fundamentals, and Propagations
Description: We empirically examine U.S. monetary policy spillovers to the Middle East and Central Asia (ME & CA) region by decomposing U.S. interest rates changes into two orthogonal shocks: the pure monetary policy shock and the information news shock. Using a sample of 16 ME & CA countries, we find that when interest rates increase, the two shocks have opposite spillovers on the region. Tightening driven by contractionary monetary policy shocks hinders growth, while tightening driven by positive information news shocks boosts growth despite higher interest rates. Countries with weaker fundamentals face more negative spillovers from contractionary monetary policy shocks but may sometimes benefit more from positive information news shocks. Moreover, high oil prices mitigate both spillovers for oil exporters while global risk appetite amplifies both spillovers. Finally, we estimate a large degree of heterogeneity in the impact of the 2022 U.S. tightening cycle on ME & CA countries, with oil exporters with stronger fundamentals withstanding well the shock and oil importers with weaker fundamentals being hit the most.

The Macroeconomic Consequences of Import Tariffs and Trade Policy Uncertainty
Description: We estimate the macroeconomic effects of import tariffs and trade policy uncertainty in the United States, combining theory-consistent and narrative sign restrictions in Bayesian SVARs. We find mostly adverse consequences of protectionism, in aggregate and across sectors and regions. Tariff shocks are more important than trade policy uncertainty shocks. Tariff shocks depress trade, investment, and output persistently. The general equilibrium import elasticity is –0.8. Historically, NAFTA/WTO raised output by 1-3% for twenty years. Undoing the 2018/19 measures would raise output by 4% over three years. The findings imply higher gains of trade than partial equilibrium or static trade models.
