La necesidad de energía la población ha originado con el paso los años problemas contaminación ambiental asociados al uso combustibles origen fósil. bioenergía es una alternativa que diversos países han propuesto para disminuir volumen gases contaminantes a atmósfera; biodiésel y bioetanol son presentan mayores ventajas comerciales en mundo, aparte necesarios cumplimiento acuerdos internacional...

Abstract Using exogenous variation in trade shocks, this study examines the association between nontariff measures and cereal production allocation decisions among commercial farmers Ghana. We from both an extensive (experience of measures) intensive (cost perspective using a sample 455 employ seemingly (un)related regression (SURE) inverse probability weighting with adjustment (IPWRA) to estim...

during the last decades a new class of materials named fiber/metal laminates (fmls) was introduced. it is a hybrid composite consisting of alternating thin layers of metal sheets and fiber-reinforced composite material. fmls have both low weight and good mechanical properties. in this study, the impact behavior of this attractive material is investigated. the effect of fiber angle, stacking seq...

sensitivity analysis with respect to the functional forms provides estimates of the uncertainties involved in choosing a specific functional structure. this is vital in cge modeling where it is conventional to take elasticities from other studies. in the present study, the robustness of model results with respect to the functional form is checked. in one scenario, the production function is rep...

selecting a set of features and price for new product is one of the most important and difficult decisions for any firm. for its implementation firms require information by demand of consumers about product features,the cost of providing these features and reaction of existing competitors to new product entry. in this research, with the help of game theory, the various positions of new product ...

The article examines the spillover effect of transition to renewable energy on different financial markets: specifically, stock market. research paper analyzes prices and dynamics oil-related assets funds, as well reviews literature topic in order evaluate most important factors development these industries. utilizes methods correlation analysis, analysis variance, regression standards deviatio...

We study supply and demand shocks in a disaggregated model with multiple sectors, factors, input-output linkages, downward nominal wage rigidities, credit-constraints, zero lower bound. use the to understand how COVID-19 crisis, an omnibus shock, affects output, unemployment, inflation, leads coexistence of tight slack labor markets. show that negative sectoral are stagflationary, whereas defla...

This study aims to determine the variation of metal transfer on tensile strength, impact, hardness distribution, macrostructure, microstructure and chemical composition low carbon steel by GMAW welding method. The material used in this was AISI 1018 steel. welded using Variation globular arc, spray arc short welding. tests carried out included testing, impact macro-structural observations, micr...

We show theoretically and empirically how real and financial frictions amplify the impact of uncertainty shocks on firms’investment, employment, debt (term structure of debt growth), and cash holding. We start by building a model with real and financial frictions, alongside uncertainty shocks, and show how adding financial frictions to the model roughly doubles the negative impact of uncertaint...
