هدف اصلی این مطالعه، بررسی رابطهی مصرف انرژی (شدت استفاده از انرژی)، رشد اقتصادی و انتشار سرانهی دی اکسید کربن، به عنوان معیاری برای آلودگی محیطزیست در ایران است. برای این منظور از داده های سری زمانی در دورهی زمانی 1383- 1346 استفاده شده است. برای برآورد مدل از روش هم انباشتگی جوهانسون- جوسیلیوس و مدل تصحیح خطای برداری (VECM) استفاده شده است. نتایج حاصل از این مطالعه نشاندهندهی وجود رابط...
Interference across competing firms in RCTs can be informative about market structure. An experiment that subsidizes a random subset of traders who buy cocoa from farmers Sierra Leone illustrates this idea. Interpreting treatment-control differences prices and quantities purchased through model Cournot competition reveals differentiation between is low. Combining result with quasi-experimental ...

We examine the impact of temperature on mortality in Mexico using daily data over period 1998–2017 and find that 3.8 percent deaths are caused by suboptimal (26,000 every year). However, 92 weather-related induced cold (<12°C) or mildly ( 12–20°C) days only 2 outstandingly hot (>32°C). Furthermore, temperatures twice as likely to kill people bottom half income distribution. Finally, we sh...
While the Earth system is in overshoot mode with an imminent threat to our social, ecological, and economic systems, cultural evolutionary theory may hold key more successfully addressing many of sustainability challenges. With aim illuminating potential studying evolution a sustainable bioeconomy through lens, this article outlines contours novel research avenue form five propositions. It cont...
Using detailed household-level data from Malawi on physical quantities of agricultural outputs and inputs, we measure farm total factor productivity (TFP), controlling for land quality, rain, transitory shocks. We find that operated size capital are essentially unrelated to TFP, implying substantial misallocation. The output gain a reallocation factors their efficient use among existing farmers...
