税收努力、征税机构与税收增长之谜

本文运用省级面板数据研究了中国税收收入高速增长的影响因素,主要考察了经济基本面和征税努力水平对于税收收入的影响。我们利用成对样本(paired sampling)的数据结构,使用工具变量处理了税收努力度量误差带来的内生性问题,估计了国税和地税机构的征税努力对于税收增长的不同影响。这种模型设定的好处是既考虑到一个地区的国税和地税面对着同样的经济基本面,同时又可以识别两个机构征税努力的增收效应所存在的差异。我们发现,GDP增长对于税收的增长有接近45%的解释力,征管努力对税收收入也有重要的贡献,地税局税收努力水平的边际效应要高于国税局的边际效应。     

Does it matter where you invest? The impact of foreign direct investments on domestic job creation and destruction

This study examines how foreign direct investment (FDI) affects domestic employment by using unique division-level data of Japanese firms. Contrary to most previous studies focusing on the effect of FDI on net employment growth, we decompose it into job creation (JC) and job destruction (JD) for each individual firm. We find that FDI destination plays an important role: FDI to Asia increases JC, whereas FDI to Europe/North America decreases it; furthermore JD decreases, regardless of FDI destination. A frictional search-and-matching model with heterogeneous jobs can explain the differential effects. The model provides additional predictions on JC and JD by job type, which are also empirically confirmed.     

An emerging market multinational Company's internationalization: From original equipment manufacturer to global brand leader

We examine an emerging market multinational company's (EMNC's) transformation from an original equipment manufacturer (OEM) to an original brand manufacturer (OBM) and global leader. Our longitudinal study of Hisense—China's largest TV company (and the world's third largest) spans three decades and involves detailed interviews with over 50 executives. We study how the company's global value chain network evolved, how it reconfigured its organization, upgraded its capabilities, and enhanced its brand reputation. We develop propositions that may contribute to improved explanations for an EMNC's internationalization sequence, development of competitive advantages, overseas management practices, and brand building.     

Model-free portfolio theory: A rough path approach

Based on a rough path foundation, we develop a model-free approach to stochastic portfolio theory (SPT). Our approach allows to handle significantly more general portfolios compared to previous model-free approaches based on Föllmer integration. Without the assumption of any underlying probabilistic model, we prove a pathwise formula for the relative wealth process, which reduces in the special case of functionally generated portfolios to a pathwise version of the so-called master formula of classical SPT. We show that the appropriately scaled asymptotic growth rate of a far reaching generalization of Cover's universal portfolio based on controlled paths coincides with that of the best retrospectively chosen portfolio within this class. We provide several novel results concerning rough integration, and highlight the advantages of the rough path approach by showing that (nonfunctionally generated) log-optimal portfolios in an ergodic Itô diffusion setting have the same asymptotic growth rate as Cover's universal portfolio and the best retrospectively chosen one.
