forecasting of macroeconomic variables has specific importance in economic topics. indeed, different models are invented to forecast variables to help economic policy makers in adopting appropriate monetary and fiscal policies. in this paper, the performance of integrated model of input-output (io) and neural network is investigated in forecasting final demand and total production and the resul...

This paper provides new empirical evidence that bears on the efficacy of unconventional monetary policies when main policy rate is negative. When a negative interest (NIRP) deployed in concert with forward guidance (FG) and quantitative easing (QE), identification impacts these instruments challenging. We propose novel approach seeks to overcome this challenge by combining dense, controlled eve...

la polymerisation thermique des huiles siccatives, en particulier l'huile de lin, semble etre une reaction bien connue . tandis que la structure des macromolecules n'est pas encore definie avec precision. on a montre que, lors de la standolisation de l'huile de jin, il se forme des aeides dimeres (c36) et trirneres (c54) , par le mecanisme de la synthese dienique, l'etude ex...

Mannases have industrial uses in food and pulp industries, and their regulation may influence development of the mushrooms of commercially important basidiomycetes. We expressed an Agaricus bisporus cel4 cDNA, which encodes a mannanase, in Saccharomyces cerevisiae and Pichia pastoris. CEL4 had no detectable activity on cellulose or xylan. This gene is the first isolated from this economically i...

Milk fat is an important food component, and plays a significant role in the economics, functional nutrition, and chemical properties of dairy products. Dairy products also contain nutritional resources and essential fatty acids (FAs). Because of the increasing demand for dairy products, milk fat is a common target in economic fraud. Specifically, milk fat is often replaced with cheaper or read...

This paper proposes tests of policy ine¤ectiveness in the context of macroeconometric rational expectations models. It is assumed that there is a policy intervention that takes the form of changes in the parameters of a policy rule, and that there are su¢ cient observations before and after the intervention. The test is based on the di¤erence between the realisations of the outcome variable of ...
