The Effects of Government Spending on the Distribution of Consumption

Giorgi, Giacomo de; Gambetti, Luca - Barcelona Graduate School of Economics (Barcelona GSE) - 2012

This paper proposes an empirical framework to study the effects of a policy regime change defined as an unpredictable and permanent change in the policy parameters. In particular I show how to make conditional forecast and perform impulse response functions and counterfactual analysis. As an...

Energy resources demand-supply system analysis and empirical research based on non-linear approach

Sun, Mei; Wang, Xiaofang; Chen, Ying; Tian, Lixin - In: Energy 36 (2011) 9, pp. 5460-5465

The three-dimensional energy resources demand-supply system is established for two regions of China, in which determination of unknown parameters is significant for the real energy resources demand-supply system. In this paper, based on Shanghai’s energy statistic data (1999–2005), the...

Identification problems in the solution of linearized DSGE models

Bonaldi, Jean Pietro - BANCO DE LA REPÚBLICA - 2010

This article analyzes identification problems that may arise while linearizing and solving DSGE models. A criterion is proposed to determine whether or not a set of parameters is partially identifiable, in the sense of Canova and Sala (2009), based on the computation of a basis for the null...

A wildland fire model with data assimilation

Mandel, Jan; Bennethum, Lynn S.; Beezley, Jonathan D.; … - In: Mathematics and Computers in Simulation (MATCOM) 79 (2008) 3, pp. 584-606

A wildfire model is formulated based on balance equations for energy and fuel, where the fuel loss due to combustion corresponds to the fuel reaction rate. The resulting coupled partial differential equations have coefficients that can be approximated from prior measurements of wildfires. An...
