Do vertical spillovers differ by investors’ productivity? Theory and evidence from Vietnam

Developing countries are eager to host foreign direct investment to receive positive technology spillovers to their local firms. However, what types of foreign firms are desirable for the host country to achieve spillovers best? We address this question using firm‐level panel data from Vietnam to investigate whether foreign Asian investors in downstream sectors with different productivity affect the productivity of local Vietnamese firms in upstream sectors differently. Using endogenous structural breaks, we divide Asian investors into low‐, middle‐, and high‐productivity groups. The results suggest that the presence of the middle group has the strongest positive spillover effect. The differential spillover effects can be explained by a simple model with vertical linkages and productivity‐enhancing investment by local suppliers. The theoretical mechanism is also empirically confirmed.     

产品开发中企业引入消费者参与的时机决策：一个基于消费者偏好信号传递的分析

针对“企业可以在产品开发的不同阶段引入消费者参与”的实践观察，本文构建消费者与企业之间的不完全信息动态博弈模型来研究“在何种条件下，企业选择产品开发前端（后端）引入消费者参与，从而激励消费者真实传递其偏好信息”这一问题。研究表明：存在外生参数（消费者讨价还价能力和参与净效用表征），使得前端和后端引入消费者参与均（或二者中只有一个）能够实现消费者真实传递其偏好信息的分离均衡；前端参与时，分离均衡要求企业通过新产品价格分担（攫取）消费者的负（正）参与净效用，而后端参与不需要这种分担（攫取）机制；在前端和后端参与均能实现消费者真实传递其偏好时，前者优于后者的条件是参与净效用为正。

经济新常态下调整和优化产业结构的财税政策

本文主要围绕三次产业的调整和优化,提出以下两个观点:一是三次产业优化应该主要依靠市场机制作用,政府的财税政策只能起助推作用,为此需要把握财税政策作用于市场的"度";二是在总结分析我国当前财税政策内容和特点的基础上,认为对于产业结构优化的需求侧财税政策弱于供给侧,今后需要加强需求侧财税政策和制度建设,并为此提出了相关的具体建议。     

The impact of prudential toolkits on loan growth in Central and Eastern European banking systems

This paper examines the effects of prudential policy on loan growth in 11 Central and Eastern European banking systems, spanning the period from 2000 to 2015. Based on the measures taken by the authorities of our sample countries, we build several prudential indices. Additionally, we control for the effects of several country-specific factors and bank-specific characteristics. Finally, we test the homogeneity of these effects, accounting for cycle, ownership, and bank effects. Generally, the empirical findings reveal a negative correlation between prudential toolkits and credit growth, with a conspicuous impact for tools targeting lending activity. We see that the effects of a change in the lending framework on loan growth are heterogeneous when we account for crisis and cycle patterns. Furthermore, the interaction between ownership and crisis reveals that, in normal times, foreign banks recorded higher loan growth compared to domestic banks. The opposite is true in turbulent times. The analysis of interactions between credit-based measures and bank-specific variables show that the effects of prudential actions depend on the bank size and leverage.

Momentum in the Chinese Stock Market: Evidence from Stochastic Oscillator Indicators

ABSTRACT

We explore whether investors earn profits through the use of stochastic oscillator indicators (SOI) for trading stocks. The results reveal that investors might use momentum strategies when trading constituent stocks of SSE 50 as the overbought trading signals emitted by SOI. We infer that the results might be caused by herding behaviors of Chinese investors since overoptimistic moods are likely to exist as evidenced by the 80 percent trading volume traded by individual investors in the Chinese stock market.
