摘要:

This study investigates financial contagion during natural disasters and explores the potential advantage of ESG investing in such contagion. Specifically, we propose using a contagion network framework to detect disaster-driven contagion and transmission channels across sectors, asset classes, and ESG international indexes. Our empirical results show the existence of the disaster-driven contagion, and most disasters increase investors’ risk aversion, which may further magnify portfolio rebalancing behavior or the wealth effect, leading to the spread of financial contagion. Moreover, we also find that the ESG market exhibits “safe-haven” properties, which contributes to the resilience of the financial system during natural disasters.

摘要:

面对新一轮科技革命和产业变革深入发展、后疫情时代经济下行风险加大、经济发展方式亟需转变等多重因素叠加,新质生产力被正式提出,而新质生产力的核心标志是大幅提升全要素生产率。全要素生产率虽是西方主流经济学的常见概念,但从思想缘起看,马克思关于提高劳动生产率的认识中蕴含着全要素生产率思想。作为社会化生产条件下劳动生产率的重要内容,全要素生产率进一步体现在两种含义的 “社会必要劳动时间”范畴上。从马克思主义政治经济学视角重新审视全要素生产率,并将其纳入中国特色社会主义政治经济学理论体系之中,是中国特色社会主义政治经济学 “不忘本来、吸收外来、面向未来”的生动写照。实践层面,经济长期高速发展带来生产方式变迁,基于新古典增长理论的传统增长核算不再适用于中国全要素生产率的实践检验,有必要从马克思的生产劳动理论出发,明确生产劳动所涉部门,由此测算得出的全要素生产率及其变动情况更具针对性。立足新时代新征程,作为实现我国经济高质量发展的关键抓手,着力提高全要素生产率需平衡好长期与短期、供给与需求、总量与结构等多个方面,在供需协调发展中推动经济发展质量变革、效率变革和动力变革,加快发展新质生产力。

主讲人简介:

Chang Liu is a Lecturer in Economics at the UNSW Business School. His research is primarily in pure and applied microeconomic theory. He is particularly focused on the equilibrium behavior and the design of mechanisms in settings where dynamic considerations are significant features of the environment. Prior to joining UNSW, he was a Postdoctoral Fellow at the Simons Laufer Mathematical Sciences Institute (SLMath, formerly MSRI). He holds a Ph.D. in Economics from Harvard University.

摘要:

We study a two-period moral hazard problem; there are two agents, with action sets that are unknown to the principal. The principal contracts with each agent sequentially, and seeks to maximize the worst-case discounted sum of payoffs, where the worst case is over the possible action sets. The principal observes the action chosen by the first agent, and then offers a new contract to the second agent based on this knowledge, thus having the opportunity to explore in the first period. We introduce and compare three different notions of dynamic worst-case considerations. Within each notion, we define a suitable rule of updating and characterize the principal's optimal payoff guarantee. We find that linear contracts are robustly optimal not only in static settings, but also in dynamic environments with exploration.

摘要:

This paper develops a model to examine the formation of influencer networks in user-generated content markets. Unlike previous research, we find that every strict equilibrium network exhibits a nested, upward-linking structure where multiple levels of influencers can coexist. Moreover, across a broad range of parameters, all payoff dominant strict equilibria conform to the law of the vital few: regardless of the population size, a small but significant group of players provides all content. We also establish a link between efficiency and equilibrium, and shows that all efficient strategy profiles are strict equilibria of an auxiliary game with larger benefit parameters. For sufficiently large populations, a single nested upward-linking network connecting all players can emerge, despite potentially polarized tastes over content categories.

摘要:

Paying negative interest rates on central bank digital currency (CBDC) becomes increasingly relevant to monetary operations, since several major central banks have been actively exploring both negative interest rate policy and CBDC after the Great Recession. This paper provides a formal analysis to evaluate the macroeconomic impact of negative interest rates on CBDC through the lens of a neoclassical general equilibrium model with monetary aggregates. In the benchmark model, agents have access to two types of assets: CBDC and productive capital. The demand for digital currency is motivated by a liquidity constraint. I show that paying negative interest on CBDC induces agents to save less and consume more via a substitution effect. A drop in savings in turn causes a fall in capital investment, subsequent output, and real money balances. To clear the money market, the price level increases. I then extend the model to include government bonds which deliver a positive return. This allows me to study a non-trivial portfolio effect: when the government pays a negative interest rate on CBDC, the tax on agents' capital spending increases, inducing a decrease in capital investment and an increase in government bonds in agents' portfolio. Such a policy causes a drop in investment and output. However, there is a transitory decline in the price level due to a "flight to quality".
