e-HKD Pilot Programme

The e-HKD Pilot Programme is a key component of the HKMA's three-rail approach in paving the way for a possible implementation of a retail central bank digital currency (CBDC). The pilot programme enables HKMA's collaboration with the industry to examine innovative use cases and maximise Hong Kong's readiness for a potential e-HKD. The Hongkong and Shanghai Banking Corporation Limited (HSBC) was one of the institutions selected to participate. Collaborating with the Hong Kong University of Science and Technology (HKUST), HSBC sought to explore possible e-HKD every-day payment use cases, focusing on programmability as a value-add feature of digital currency as well as payment rail efficiency. HSBC and HKUST constructed a one-week pilot on the HKUST campus, which included 148 students and 5 merchants. Read more

Infrequent but long-lived zero lower bound episodes and the optimal rate of inflation

Published in Annual Review of Economics, 2016

Countries rarely hit the zero lower bound (ZLB) on interest rates, but when they do, these episodes tend to be very long-lived. These two features are difficult to incorporate jointly into macroeconomic models using typical representations of shock processes. We introduce a regime-switching representation of risk premium shocks into an otherwise standard New Keynesian model to generate a realistic distribution of ZLB durations. We discuss what different calibrations of this model imply for optimal inflation rates. Read more

Efficiency, Risk and the Gains from Trade in Interbank Markets

We propose a model of the financial sector that captures complex relationships between highly heterogeneous agents in the market for loanable interbank funds and develops the bank-to-bank component of the macroeconomics financial transmission channel. Financial institutions trade funds due to heterogeneous capacity to provide liquidity, but trade is subject to frictions and uncertainty. The model provides a tractable framework to study the trade-off between efficiency and volatility in the financial sector, and its contribution to business cycles fluctuations. Read more

Endogenous Firm Entry and the Supply-Side Effects of Monetary Policy

We present a model of business cycles with endogenous firm entry. In our framework, short-term supply shifts driven by new firm entries become a crucial factor in driving the economy's response to shocks, regardless of whether those shocks originate from the 'supply' or 'demand' blocks. Specifically, an uptick in aggregate demand triggers a cycle of increased firm entry, thereby enhancing aggregate supply and, in turn, further boosting demand through greater purchases of equipment by new entrants. Monetary policy becomes especially powerful, as it simultaneously impacts aggregate demand and the entry decisions of financially constrained firms. This effect is particularly noticeable in economies with a significant potential for new firm entries. Our analytical approach characterizes equilibrium firm entry as a function of the 'policy room', a sufficient statistic related to the effectiveness of monetary policy interventions in both the model and the data.

Higher-Order Forward Guidance

This paper presents a model of the business cycle that incorporates financial markets and endogenous financial volatility at the Zero Lower Bound (ZLB). Within this framework, forward guidance is identified as a crucial mechanism for coordinating the actions of market participants, guiding the economy towards optimal equilibrium paths with lower financial volatility and enhanced welfare. We reveal three novel insights: (i) Central banks, by credibly pledging future economic stabilization, can mitigate excess financial market volatility at the ZLB; (ii) Alternatively, a central bank's commitment not to stabilize the economy in the future can direct the economy towards more favorable equilibrium paths with reduced endogenous volatility at the ZLB, presenting a trade-off between future business cycle stabilization and reduced financial volatility at the ZLB; (iii) Retaining some degree of uncertainty regarding the timing of future stabilization plans strictly dominates other forms of forward guidance commitments. Finally, an examination of alternative fiscal policies reveals that measures encouraging increased investment in risky assets can stimulate economic activity at the ZLB by positively impacting aggregate household financial wealth.

Self-fulfilling Volatility and a New Monetary Policy

We demonstrate that macroeconomic models with nominal rigidities feature multiple global solutions supporting alternative equilibria traditionally overlooked in the literature. In these equilibria, conventional Taylor rules give rise to self-fulfilling aggregate volatility, propelling the economy into crises (booms) characterized by elevated (reduced) aggregate risk. This outcome stems from the inability of conventional rules to target the expected growth rate of output, which is determined not only by the policy rate but also by the strength of the precautionary savings channel. We propose a new policy rule that targets both conventional mandates and aggregate volatility, reestablishing determinacy and achieving full stabilization. Read more

A Unified Theory of the Term-Structure and Monetary Stabilization

We develop a New-Keynesian framework that incorporates the term-structure of financial markets and emphasizes the active role of the government and central bank's balance sheet size and composition. We demonstrate that the financial market segmentation and the household's endogenous portfolio reallocation are crucial features for accurately understanding the effects of Large-Scale Asset Purchase (LSAP) programs. Our micro-foundation based on imperfect information about expected discounted asset returns readily accommodates varying degrees of market segmentation across asset classes and maturities, based on estimable asset demand elasticities. The central bank's bond purchases across maturities serve as a major determinant of the level and slope of the term-structure, and yield-curve-control (YCC) policies that actively manipulate long-term yields are highly effective in terms of stabilization during both normal times and at the ZLB. However, YCC policies also increase the duration of ZLB episodes, consequently placing the central bank in a position where the short-term rate becomes a less useful policy tool. Read more

Gender Gap, Structural Change and Female Comparative Advantage: A Quantitative Analysis of China

This paper presents a theoretical framework to reconcile the declining female labor force participation (FLFP) rate and the diverging gender gap in workforce participation in China with the expansion of the service sector and with the increasing female comparative advantage in the market sectors. We argue that two factors jointly shape the trajectory of FLFP rate and gender gap in labor force participation: (i) the interaction between structural change and female comparative advantage dynamics, and (ii) the change of female comparative advantage in the market sectors relative to home production. The framework predicts that FLFP rate drops when women have comparative advantage in diminishing sectors and vice versa, and that a rise in female comparative advantage in the market sectors narrows gender differences in labor force participation.
