I just wrote a substack post about my insights into slavery and power. The logic behind slavery is never the ownership over human, but the dependency on others. open.substack.com/pub/karl8739...

visionary/visionär这个词我很喜欢,它有两个意思,第一个是幻觉的,幻象的,天马行空的:in der Art einer Vision, traumhaft;第二个是有远见的,有洞察力的(并且能以艺术、技艺的方式实现的):Visionen der Zukunft habend (und künstlerisch gestaltend), seherisch. 这两个意思连接在一个词里指出了“洞察力”和“预见性”的一个重要方面就是想象力和非理性,这是用中文没法直接发现和理解的联系。扼杀想象力也是在扼杀有远见的人。

Participate the IAREP in Tartu, Estonia. I presented my first year’s PhD work: Modern Slavery and Mistrust. I am glad that I am awarded the second best PhD student paper by IAREP and ELSEVIER! This recognition is truly motivating, especially given the high quality of research presented! #IAREP2025

Economists Are in the Wilderness. Can They Find a Way Back to Influence?
Economists have long helped to shape policy on issues like taxes and health care. But flawed forecasts and arcane language have cost them credibility.

Two aspects of economists (so far as I understand): Aspect of engineer: solving optimization problems for the allocation of scarce resources or human interaction. Aspect of philosopher: define a meaningful question on human behavior, and formulate it by the language of economic reasoning.

Problem versus opportunity: Implications of immigration for workers’ welfare and entrepreneurship in Germany
Recent worldwide socioeconomic and political developments have increased immigration pressure on developed economies. Receiving countries are putting enormous efforts into understanding the repercussions of immigration better, particularly the refugee waves. This column describes how in Germany, one of the largest recipients of refugees, different demographic groups experienced heterogeneous welfare effects of immigration between 2012 and 2017, with marginal losses to the welfare of the average worker. These losses can be partly mitigated by the recently established cooperation on worker mobility between Germany and India.
