These are 10 of my favourite #UrbanEconomics articles published in 2020, in alphabetical order by author, continuing with a tradition from the last couple of years

1) @TrebAllen, Arkolakis & Takahashi, JPE. Shows key theoretical properties & predictions of large class of trade/geography gravity models depend on 2 parameters: elasticities of supply and demand. Proposes IV estimation strategy relying on GE structure https://t.co/5On1AQkbeP
2) Ambrus, Field & @rmgonzalez046, AER. 1854 London: prices fell in blocks served by well transmitting cholera. Differences persist. Model: tenants change as contracts expire, -ve externality of poor tenants, shock makes landlords persistently target poor https://t.co/6uaxjG6Bmf
3) @kon_buechel & @maxvehrlich, JUE. More sociable individuals sort into cities. Even after accounting for sorting, those in denser areas call each other more often & longer, suggesting complementarity between face-to-face and phone interactions https://t.co/bymmL4PzaJ
4) @CarozziFelipe, JEEA. Shows how credit constraints affect composition of housing sales & access to home-ownership by the young. Neat model of housing markets as ladders with young in cheap units, possibly trading up as they age, post-2008 UK evidence https://t.co/PCn7w35Qu8
5) Harari, AER. City shape matters. More compact (circular) Indian cities grow faster (IVs compactness with mechanical expansion + geographic constraints). Compactness affects road network, location patterns, quality of life. Regulations affect shape https://t.co/TbXX9X4qwC
6) Heblich, @ReddingEcon & Sturm, QJE. Uses quantitative urban model & spatially disaggregated data for London 1801-1921 to explore how steam railways triggered workplace-residence separation, enabling substantial agglomeration in production & residence https://t.co/Z0CnPlQnMY
7) Liu, Rosenthal & Strange, RSUE. Agglomeration in tall buildings depends on street access, height amenities & productivity. Ground & high floors most valuable. Density & law firm sales indicate strong same-floor spillovers quickly attenuating vertically https://t.co/YxXFQ4yydZ
8) @OtoPeralias, JDE. Explores origins of settlement patterns exploiting spatial discontinuity in insecurity in medieval Spain. Frontier warfare encourages population concentration in few livestock-oriented (vs. agriculture) settlements, strong persistence https://t.co/FkXwJ9EohA
9) Owens, @HansbergRossi & Sarte, AEJEcPol. Rationalises healthy Detroit CBD surrounded by vacant land through model with residential externalities leading to coordination problem, evaluates development guarantees & other alternatives https://t.co/WMQiUhWf46
10) @piazzesi, Schneider & @stroebel_econ, AER. Housing search model with many segments, agents with different search ranges, broad searchers that narrow down by segment inventory. Helps think about Beveridge curve, scope & connectedness in housing markets https://t.co/wmpnDqsoL1

True that all the people cherishing the support of IMF or WTO for farm reforms need to cool it down a bit, because that is a model we do not want to emulate to the t in India here.

But here are some issues that deserve to be better discussed by all:


1. People who say we are emulating the Western model of agriculture are way off with this assumption. The process of primitive accumulation, the alienation of their people from their land and the way these 'first-world' countries have pushed their people into Industrial sector +

But the same assumption won't work for India, because we have always had a large workforce in agriculture, agri subsidies have always run high, protection has been the hallmark of agriculture and rural representation in the parliament has always been+

महाभारत की कहानी कौन नहीं जानता।लेकिन क्या आपको पता है कि महाभारत के ज्यादातर पात्र किसी न किसी श्राप में फंसे थे।अगर ये श्राप न होते तो कदाचित महाभारत की कहानी कुछ और होती।हिन्दु पौराणिक ग्रंथों में विभिन्न श्रापों का वर्णन मिलता है व हर श्राप के पीछे कोई कहानी अवश्य होती है।


आइए आज जानते हैं महाभारत कथा में वर्णित कुछ श्रापों के बारे में।

1) राजा पाण्डु को ऋषि किन्दम का श्राप

एकबार महाराज पाण्डु शिकार खेलने वन गए।झाडियों के पीछे कुछ हिल रहा था। मृग है सोचकर राजा ने बाण चलाया जो जाकर ऋषि किन्दम और उनकी पत्नी को लगा।वे दोनो रति-क्रीड़ा में लिप्त थे।

जब राजा ने उन्हें देखा तो बहुत दुखी हुए कि ये मुझसे क्या पाप हो गया।बहुत क्षमा याचना के बाद भी किन्दम ऋषि ने पाण्डु को श्राप दे दिया कि जब भी वो किसी स्त्री को काम भावना से स्पर्श करेंगे उसी क्षण उनकी मृत्यु हो जाएगी।पश्चाताप करने, वे सिंहासन पे अन्धे राजा धृतराष्ट्र को बैठाकर...


..स्वयं अपनी रानियों कुंती व माद्री के साथ वन चले गए।पांडवों का जन्म भी कुंती को ऋषि दुर्वासा द्वारा दिए गए मंत्र से हुआ था जिसमे किसी भी देव का स्मरण कर उस देव से कुंती,पुत्र प्राप्त कर सकती थी।एक बार माद्री पे मोहित हो जब पांडु ने उसे स्पर्श किया,उसी क्षण पांडु की मृत्यु होगयी।


2) उर्वशी का अर्जुन को श्राप

महाभारत युद्ध से पहले जब अर्जुन दिव्यास्त्र प्राप्त करने स्वर्ग गए तो वहां उर्वशी नाम की अप्सरा उन पर मोहित हो गयी। अर्जुन ने जब उन्हें अपनी माता के समान बताया तो यह सुनकर उर्वशी क्रोधित हो गयी और अर्जुन को श्राप दे डाला कि तुम नपुंसक की भांति...
And here they are...
