  摘记:

  People are embedded in multiple social relations. These relations are not isolated from each other. Do different networks overlap and why? We focus on the following question: When an agent has a new relation to add, would they choose to multiplex, i.e., to link with a friend or a stranger? The key tradeoff that we emphasize is the one between multiplexity and community enforcement. Multiplexity enhances cooperation because various relations serve as social collateral for each other, while linking to a stranger can utilize community enforcement, whose power relies more on the rest of the network structure. We find the following: (1) There is a strong tendency to multiplex, and the “multiplexity trap” can occur; that is, agents may keep adding relationships with friends, even when it is more efficient to link with a stranger. (2) Agents tend to multiplex when the existing network (a) has a low degree dispersion (i.e., all agents have similar numbers of friends) or (b) is positively assortative (agents are linked with those with a similar number of friends). We also find that agents tend to multiplex when the new relationship is more important. Using the Indian Village Survey data, we provide supportive evidence for our theoretical predictions.

  主讲东说念主简介:

  Melanie Xue is a tenure-track assistant professor (September 2020- ) in the Social Science Division at New York University (AD), a member of the economic history group. Before joining NYU AD, she spent time at UCLA and Northwestern. She will be joining the London School of Economics in September 2021. 

  摘记:

  We use a difference-in-differences strategy to study the effects of "affirmative action” policies on human capital accumulation, social mobility and regional inequalities. Qing China used an examination system to select government officials. Successful candidates became shengyuan, juren & jinshi. We examine a policy reform in 1712 which allowed individuals from underrepresented provinces to become jinshi with lower scores. The reform led to an overall increase in the number of jinshi in underrepresented provinces, closing the gap between provinces. Such gains, however, were concentrated in the very few prefectures that had the most jinshi prior to the reform, resulting in increasing inequalities between prefectures within provinces.

Mapping US-China Technology Decoupling, Innovation, and Firm Performance

  上流(北京大学经济学院副考验)

  诠释摘记:

  Based on the combined patent data from the U.S. and China, we quantify the technology decoupling and dependence between the two countries. The first two decades of the 21st century witnessed a continuing increase in technology integration (or less decoupling), but China’s technology dependence on the U.S. increases (decreases) during the first (second) decade. A panel VAR analysis suggests that a higher level of decoupling in a given technology field predicts more dependence of China on the U.S., which in turn predicts less decoupling. Decoupling is associated with more patent outputs in the given sector in both countries, lower firm productivity and valuation in China, but no significant impact on U.S. firms. Finally, China’s innovation-oriented industrial policies are associated with both more integration with and less dependence on U.S. technology down the road, trading off the inherent conflict between the two main policy objectives of promoting indigenous innovation versus enhancing firm competitiveness. U.S. sanctions against China have neither led to US-China technology decoupling nor strangled Chinese firms in the sanctioned sectors.

His primary research focuses on developing and justifying econometric methodology and applications in economics and finance. His work has been published extensively in professional journals, including both leading econometrics and statistics journals: Journal of Econometrics, Econometric Theory, The Journal of American Statistical Association, and more.

  摘记:

  The degree of interdependences among holdings of financial sectors and its varying patterns are key in forming systemic risks within a financial system. In this article, we propose a VAR model of conditional quantiles with functional coefficients to construct a novel class of dynamic network system, of which the interdependences among tail risks such as Value-at-Risk are allowed to vary with a variable of general economy. Methodologically, we develop an easy-to-implement two-stage procedure to estimate functionals in the dynamic network system by the local linear smoothing technique. We establish the consistency and the asymptotic normality of the proposed estimator under time series settings. The simulation studies are conducted to show that our new methods work fairly well. The potential of the proposed estimation procedures is demonstrated by an empirical study of constructing and estimating a new type of dynamic financial network.

  摘记:

  We study the optimal taxation and government asset price volatility in economy with incomplete markets. With quasi-linear preference, any finite asset limit is sustainable and the Ramsey government would play a Ponzi game if there is no asset limits. When taxes or assets are confined by additional limits, the asset accumulation process becomes ergodic even when the government expenditure follows a Markov process. Furthermore, we show that the celebrated Martingale convergence result in the literature is due to the weak precautionary savings motive by the government. Once the government has sufficiently strong precautionary savings motive, the ergodic property of asset accumulation process will return. When utility functions present income effects, the bond prices become endogenous. With sufficiently large initial asset position, the government may command near zero群交淫乱, and even negative interest rate to offload household’s debt obligation. This justifies the sustainability of initial asset/debt in the first place. Subsequently, the asset price may present volatility with an order of magnitude larger than what the primitive of the economy would imply. Our findings indicate that the optimal taxation and government asset management has complicated relationships with significant implications on asset pricing.
