The acquisition and dispersion of information, a critical aspect of economic decisions, can occur through a network of agents (Jackson, 2009). Empirical and theoretical findings suggest that an efficient information dispersion network takes the form of a star: small numbers of agents gather information and distribute it to a large group. Despite these findings, controlled tests of this theory f...
We investigate the incentive and project screening effects of anonymity in the peerreview process. If the process is “blind”, then the applicant’s (payoff relevant) type is hidden from the reviewer. If the process is nonblind or “informed”, then the reviewer observes the applicant’s type directly. In either case, the evaluator receives a noisy signal on the quality of the agent’s project and de...
Egalitarianism and meritocracy are competing principles to distribute the joint bene ts of cooperation. We examine the consequences of letting members of society vote between those two principles, in a context where groups of a certain size must be formed in order for individuals to become productive. Our setup induces a hedonic game of coalition formation. We study the existence of core stable...
This paper applies a novel methodology to measure corruption levels in U.S. states, leading to insights which could be useful to policymakers in their effort to reduce unethical behavior. The level of public corruption is difficult to quantify because much of it goes undetected and because different cultures and jurisdictions have different definitions and different degrees of tolerance for cor...
بازار کالاهای اعتباری یکی از بازارهایی است که وجود اطلاعات نامتقارن، آن را به بازاری مفقود شده تبدل کرده است. از آن جایی که خریداران کالاهای اعتباری معمولاً به دلیل عدم توانایی در تعیین دقیق تقاضای خود، قادر به برطرف کردن عدم تقارن اطلاعات خود نیستند، بنابراین نفعطلبی و سودجویی افراد متخصص ممکن است با دروغ گفتن به مشتری، انجام ندادن درست کار و یا گرفتن حقالزحمهی بیشتر، سبب تحمیل هزینهی اضاف...
In this article aging behavior of composite solid propellant was investigated by determining its mechanical properties at elevated temperatures. For this purpose, three HTPB samples with different microstructures were selected and composite solid propellants were prepared based on them keeping similar other components and aging was studied by accelerated method. Mechanical properties were meas...
ABSTRACT The Deep Extragalactic VIsible Legacy Survey (DEVILS) is an ongoing high-completeness, deep spectroscopic survey of ∼60 000 galaxies to Y < 21.2 mag, over ∼6 deg2 in three well-studied extragalactic fields: D10 (COSMOS), D02 (XMMLSS), and D03 (ECDFS). Numerous DEVILS projects all require consistent, uniformly derived state-of-the-art photometric data with which measure galaxy pr...
The expansion of the research on nanoscale particles demonstrates several advantages in terms stability and an increased surface area to volume ratio compared micron-sized particles. Based this, present work explores addition aluminum hydrotreated vegetable oil (HVO), alternative jet fuel. To evaluate influence particle sizes, nano micron (40 nm 5 ?m) a concentration 0.5 wt.% were stably suspen...
یکی از مراحل مهم در اکتشاف ذخایر معدنی، شناسایی مناطق هدف است. روش های پلاریزاسیون القایی و مقاومت ویژه، روش های مناسبی به منظور پی جویی و اکتشاف کانی سازی سولفیدی می باشند. منطقه دره-اشکی به عنوان منطقه مورد مطالعه، یکی از 9 کانسار شناخته شده منطقه بزرگ موته به وسعت 150کیلومتر مربع است. با توجه به شواهد کانی سازی سولفیدی در منطقه دره اشکی، عملیات ژئوفیزیکی با چهار پروفیل مستطیلی با فواصل بین پ...
Abstract. This paper presents a three-dimensional variational (3DVAR) data assimilation (DA) system for aerosol optical properties, including thickness (AOT) retrievals and lidar-based profiles, developed the Model Simulating Aerosol Interactions Chemistry (MOSAIC) within Weather Research Forecasting model coupled to (WRF-Chem) model. For computational efficiency, 32 variables in MOSAIC_4bin sc...
