产品差异度与厂商共谋行为——模型与实验证据

对该问题的研究,除了来自理论观点和政策角度的兴趣外,此类实验的空白也是其中之一.标准的默契共谋理论认为在线性需求条件下价格和产品差异度之间没有明显的联系,其他一些理论例如价格匹配理论则认为两者之间存在单调关系.我们沿着Bertrand理论渊源构建了模型,并设计产品差异度和默契共谋的实验室实验,在实验室环境里检验产品差异度和共谋之间的关系.我们的实验结果证伪了纳什回归模型,基本证实了价格匹配模型和T时期惩罚模型.     

Real exchange rate shocks and new product margins in the export market

This study examines the impact of industry real exchange rate (RER) shocks on plant and product exports using a comprehensive dataset for South Korea from 1990 to 1996. We find that RER changes have heterogeneous effects on real exports of existing exporters in terms of their productivity, and the positive RER depreciation effect on exports is more pronounced for less productive plants. At a product level, we find new evidence that a weak home currency prompts exporters to introduce new products to the export market, especially more remarkable for low-productivity plants. In contrast, a strong home currency leads to product exit with less significance.

Auditors’ scepticism in response to audit committee oversight behaviour

We use two experiments and a survey to examine how audit committee (hereafter, AC) oversight behaviour, particularly AC sceptical attitude and proactive behaviour, affects auditor scepticism, and whether the influence is driven by the risk aspect of auditors’ assessment of AC oversight behaviour. We find that when ACs exercise insufficient scepticism, auditors (junior auditors, managers, and partners) perceive AC oversight as weak, and increase their scepticism. However, AC proactive behaviour does not significantly influence auditor scepticism. Our findings suggest auditors view weak AC oversight as a risk indicator and respond by exercising greater scepticism.     

National Concentration of High-tech Products: The Second Great Divergence?

Based on the product-country level trade data from 2004 to 2017, as well as the High-Tech Products Catalog from the US Census Bureau, this paper examines empirically the current phenomenon of “national concentration” in high-tech exports. The results show that the phenomenon of “national concentration” not only exists but also tends to be self-reinforcing. Compared with other products, the exports of high-tech products tend to be concentrated in certain countries, and this concentration trends were further strengthened after the global financial crisis of 2008–2009. The national concentration of R&D activities may be one of the important causes of the national concentration of high-tech products. This pattern remains robust when we further use the value-added export data and different definitions of high-tech products. We argue that the phenomenon of “national concentration” of high-tech exports may herald the arrival of the “Second Great Divergence” – the divergence between innovative and manufacturing activities – in the global economy.
