Humans are increasingly subsidizing and altering natural food webs via changes to nutrient cycling and productivity. Where human trophic subsidies are concentrated and persistent within natural environments, their consumption could have complex consequences for wild animals through altering habitat preferences, phenotypes and fitness attributes that influence population dynamics. Human trophic ...

Utility subsidies are often defended as promoting universal service. However, specific support formulas may be poorly targeted and/or designed. The U.S. high cost loop support (HCLS) program (formerly referred to as the Universal Service Fund (USF)), has been a key component of the FCC’s USF program. With proposed initiatives for universal access to broadband, it is useful to critically evaluat...

We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation– in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to clean technology can be diffi cult both because clean research must climb several rungs to catch up with ...

Federal rental subsidies appear to create disincentives for work through marginal taxes on earnings, income effects, and requirements that nonrecipients on waiting lists maintain low incomes in order to remain eligible. This paper takes advantage of the rationing of housing subsidies by identifying labor supply effects using analytic methods that could not be validly applied to unrationed progr...

This paper focuses on the role that production subsidies play in a Bertrand mixed duopoly. The paper examines four regimes: mixed and private duopoly, each with and without subsidies. The results of this study are compared with the findings of the existing Cournot mixed market literature. As a result, the paper shows that that the introduction of production subsidies into the analyses of Bertra...

Abstract This study reviews the direct and indirect effects of higher energy and bread prices (due to removing their subsidies and paying their equivalent in cash instead). Therefore, all consumer goods were classified into 6 groups and a linear expenditure system was estimated based on households’ budget data of 2009 and 2011 for urban and rural areas separately. The results indicate that hi...

Recent years have seen a resurgent interest in large scale input subsidies, and particularly fertilizer subsidies, in agricultural development and food security policies in Africa. Very high global grain prices in the first part of 2008 appeared to make such subsidies even more attractive, but this was complicated by even more dramatic rises in fertilizer prices. Global grain and fertiliser pri...

If dirty technologies are more advanced to start with, the potential transition to clean technology can be diffi cult both because clean research must climb several rungs to catch up with ...

this paper estimates the trend of total energy subsidies from year 2003 (that is 16.68% of gdp) and running a model, predicts that energy subsidies will reach to 20% of gdp by 2019 if subsidies continue. also environmental damage costs of energy consumption have been entered the model (environmental cost-benefit analysis model: ecba model) in addition to the vast amounts of subsidies. so damage...
