TL;DR: The Varian approach as mentioned in this paper gives students tools they can use on exams, in the rest of their classes, and in their careers after graduation, and is still the most modern presentation of the subject.
Abstract: This best-selling text is still the most modern presentation of the subject. The Varian approach gives students tools they can use on exams, in the rest of their classes, and in their careers after graduation.

TL;DR: It is shown how it is possible to schedule users by applying an original model to represent the behavior of multimedia users so as to obtain a more efficient resource usage, characterized by both larger users’ appreciation and higher revenue for the service provider.
Abstract: Recently, several proposals for wireless scheduling algorithms have been presented, using allocation models focused on users’ subjective perception of the service. The goal of these investigations is to design scheduling policies aimed at satisfying more directly the users’ preference. In this paper we extend this approach, by studying Radio Resource Management, and in particular the scheduler, considering an original model to represent the behavior of multimedia users. We include charging strategies and users’ reaction to prices, so that qualitative and quantitative economic considerations are directly included. After a brief discussion on how to include both perceived quality and pricing, in order to achieve a user-centric evaluation of the QoS, we show how it is possible to schedule users by applying this model so as to obtain a more efficient resource usage, characterized by both larger users’ appreciation and higher revenue for the service provider.

TL;DR: In this article, the authors discuss the potential economic consequences of the countervailing duty imposed on solar panels imported from China by the EU and conclude that if European producers de facto are more efficient than Chinese, the prices of solar panels may be decreased the furthest by protecting these producers from what the EU commission have declared to be unfair Chinese state aid.
Abstract: This paper discusses the potential economic consequences of the countervailing duty imposed on solar panels imported from China by the EU. The paper is motivated by recent studies that indicate potential future costs from a world energy market that is characterized by technics that give rise to high relative levels of carbon dioxide. The intention is to discuss the potential effect that countervailing duties can have on the internalization of externalities in the form of consumption of solar panels. Whether the countervailing duties represent a potential increase or decrease in the internalization of externalities comes down to the potential capabilities of European and Chinese producers. If European producers de facto are more efficient than Chinese, the prices of solar panels may be decreased the furthest by protecting these producers from what the EU commission have declared to be unfair Chinese state aid. The countervailing duties would, in the case of European comparative advantage in the production of solar panels, give rise to global economic gains in the form of higher solar panel consumption and as a consequence lower carbon footprint. Unfortunately if the Chinese producers are in fact the most efficient the duties implemented will have the opposite effect due to the increased price of solar panel consumption in Europe. Various trade theory related to production, externalities, and substitutions will be used to give a suggestion to which producer is the most efficient, and the likely consequences of European duties on global welfare. Hence the conclusion and analysis will be of a theoretical character. This is arguable to be preferred due to how recently the European decision came to implement solar panel duties. The recently of the event causes there to be very limited data available which is necessary to be able to use quantitative methods, which would otherwise at least be a good complement to the paper. This is also why future research should be concentrated at looking at the actual statistics regarding the outcome of recent events and try to build upon the conclusions expressed in this paper as well as criticize them.

TL;DR: In this paper, the existence of the quasiconvex constrained least squares estimator (LSE) was proved and a characterization of the function space to compute the LSE via a mixed integer quadratic program was provided.
Abstract: We develop a new approach for the estimation of a multivariate function based on the economic axioms of quasiconvexity (and monotonicity). On the computational side, we prove the existence of the quasiconvex constrained least squares estimator (LSE) and provide a characterization of the function space to compute the LSE via a mixed integer quadratic programme. On the theoretical side, we provide finite sample risk bounds for the LSE via a sharp oracle inequality. Our results allow for errors to depend on the covariates and to have only two finite moments. We illustrate the superior performance of the LSE against some competing estimators via simulation. Finally, we use the LSE to estimate the production function for the Japanese plywood industry and the cost function for hospitals across the US.

Abstract: 1. ВведениеМатематическое моделирование сложных экономических, технических и др. динамиче-ских процессов, функционирующих в условиях риска и неопределенности, приводит к ситуа-ции, когда явно присутствуют несколько уров-ней принятия управленческих решений при наличии конкретных условий информирован-ности и иерархической подчиненности для управляющих субъектов. Математические мо-дели таких процессов являются многоуровне-выми иерархическими динамическими систе-мами с неполной информацией, и их исследо-вание представляет самостоятельный интерес в рамках математической теории процессов управления и экономико-математического моделирования.В статье рассматривается дискретная дина-мическая система, состоящая из набора управ-ляемых объектов (региона и образующих его муниципалитетов), динамика каждого из ко-торых описывается соответствующим вектор-ным линейным дискретным рекуррентным со-отношением при наличии управляемых па-раметров и возмущений (векторов рисков). В данной системе выделены два уровня приня-тия управленческих решений — доминирую-щий (региональный) уровень
