华人经济学家在理论经济学和计量理论方面确实挺有竞争力的,不然就不会出现众多华人经济学家去担任Journal of Econometrics的主编、副主编、编委。在The Review of Economic Studies 2021年第3期就同时出现了2篇完全由华人经济学家发表的理论经济学和计量经济学文章。当然,相对于实证经济学文章,这2篇理论型很强的文章对读者的数学和经济学知识提出了更高的要求。而熟悉这个领域的学者,也知道以下四位华人经济学家在本科阶段所学专业无一例外的都是数学。
世界范围位列前500的经济学家名单, 中国经济学家一直在坚守其中!

基于似然比的马尔可夫区制转移检验

Zhongjun Qu, Fan Zhuo, Likelihood Ratio-Based Tests for Markov Regime Switching, The Review of Economic Studies, Volume 88, Issue 2, March 2021, Pages 937–968, https://doi.org/10.1093/restud/rdaa035

Markov regime-switching models are very common in economics and finance. Despite persisting interest in them, the asymptotic distributions of likelihood ratio-based tests for detecting regime switching remain unknown. This study examines such tests and establishes their asymptotic distributions in the context of nonlinear models, allowing multiple parameters to be affected by regime switching. The analysis addresses three difficulties: (i) some nuisance parameters are unidentified under the null hypothesis, (ii) the null hypothesis yields a local optimum, and (iii) the conditional regime probabilities follow stochastic processes that can only be represented recursively. Addressing these issues permits substantial power gains in empirically relevant settings. This study also presents the following results: (1) a characterization of the conditional regime probabilities and their derivatives with respect to the model’s parameters, (2) a high-order approximation to the log-likelihood ratio, (3) a refinement of the asymptotic distribution, and (4) a unified algorithm to simulate the critical values. For models that are linear under the null hypothesis, the elements needed for the algorithm can all be computed analytically. Furthermore, the above results explain why some bootstrap procedures can be inconsistent, and why standard information criteria can be sensitive to the hypothesis and the model structure. When applied to US quarterly real gross domestic product (GDP) growth rate data, the methods detect relatively strong evidence favouring the regime-switching specification. Lastly, we apply the methods in the context of dynamic stochastic equilibrium models and obtain similar results as the GDP case.

多边市场中竞争和进入的影响

Guofu Tan, Junjie Zhou, The Effects of Competition and Entry in Multi-sided Markets, The Review of Economic Studies, Volume 88, Issue 2, March 2021, Pages 1002–1030, https://doi.org/10.1093/restud/rdaa036

We study price competition and entry of platforms in multi-sided markets. Utilizing the simplicity of the equilibrium pricing formula in our setting with heterogeneity of customers’ membership benefits, we demonstrate that in the presence of externalities, the standard effects of competition can be reversed: as platform competition increases, prices, and platform profits can go up and consumer surplus can go down. We identify economic forces that jointly determine the social inefficiency of the free-entry equilibrium and provide conditions under which free entry is socially excessive as well as an example in which free entry is socially insufficient.
