The evolution of world trade from 1995 to 2014: A network approach

This paper employs network analysis to study world trade from 1995 to 2014. We focus on the main connective features of the world trade network (WTN) and their dynamics. Results suggest that countries’ efforts to attain the benefits of trade have resulted in an intertwined network that is increasingly dense, reciprocal, and clustered. However, these features do not correspond to a linear aggregation of the characteristics of its constituents (trade sectors). Trade linkages are distributed homogeneously among countries, but their intensity (i.e. their value) is highly concentrated in a small set of countries. The main connective features of the WTN were not affected by the 2007–2008 international financial crisis. However, we find that the crisis marks a turning point in the evolution of the WTN from a two-group (led by the US and Germany) to a three-group (led by the US, Germany, and China) hierarchical structure.

Pairwise epistemic conditions for Nash equilibrium

We introduce a framework for modeling pairwise interactive beliefs and provide an epistemic foundation for Nash equilibrium in terms of pairwise epistemic conditions locally imposed on only some pairs of players. Our main result considerably weakens not only the standard sufficient conditions by Aumann and Brandenburger (1995), but also the subsequent generalization by Barelli (2009). Surprisingly, our conditions do not require nor imply mutual belief in rationality.     

On the conceptual foundations of financial reporting

Standard setters advocate a balance sheet approach to financial reporting, which views assets and liabilities as primary, and income as just the derivative change in net assets. This paper argues that income is conceptually and practically better described as ‘adjusted net cash flows,’ where the adjustments are the accounting accruals. One proof of that is seen in the existence of whole accounting systems like tax accounting and national income accounting, which emphasize the determination of income but have no balance sheets. The paper also argues that an income-based approach to financial reporting is by nature better suited to reflect the success of advancing cash to earn more cash, which defines what for-profit entities do. There are two main features of the income-based approach. One is attention on the cash flows as the natural foundation for financial reporting because they are precisely determined, and provide a clear link to firm valuation. The other is attention on the accounting accruals, which serve to adjust the raw cash flows to better show the current success of investing cash to ultimately earn more cash. Specifically, the paper argues for revenue recognition which is close to current practice, and for expense recognition which is aligned with the matching principle.     

网络流行语“中国大妈”和“中国式X”解析--基于认知及社会文化维度

伴随着新媒体的发展，“中国大妈”和与其结构类似的“中国式X”的网络流行语正在受到越来越多的关注。代表一种独特的文化现象的“中国式X”，本身就是一个语言模因，它的各种次生语言形式在模因的作用下得以在社会大众之间广泛繁殖和衍生。我们既可以从认知语言学的概念重叠和概念整合角度对“中国大妈”的形成及其所隐含的调侃语义进行解读，也可以从社会文化学领域的模因论视角对“中国式X”的传播进行探讨。

概念整合理论对诗性隐喻的认知阐释

诗歌是一种独特的语言形式,充满了隐喻,因而它被称为"隐喻性语言"。一个隐喻可以同时在不同的图标层面解释,从最抽象的认知方面到最具体的感官认知,将时空的维度组织成"认知域"。本文从认知的新视点出发,用概念合成理论来解读狄金森和弗罗斯特诗歌的诗性隐喻,以期更好地欣赏其诗歌。
