The Political Economy of Global Warming. From Data to Decisions

Larsen, Erling Røed - Statistisk Sentralbyrå, Government of Norway - 2002

This article studies the process from data acquisition to policy decision in relation to an optimum policy on global warming. Policymakers must be reasonably skeptical before proposing remedies to curb warming, but policymakers cannot await the final proof of any proposal's merit. Balancing...

Evaluation and Combination of Conditional Quantile Forecasts

Giacomini, Raffaella; Komunjer, Ivana - Department of Economics, University of California-San … - 2002

This paper proposes a method for comparing and combining conditional quantile forecasts based on the principle of 'encompassing'. Our test for conditional quantile forecast encompassing (CQFE) is a test of superior predictive ability, constructed as a Wald-type test on the coefficients of an...

US monetary policy rules : the case for asymmetric preferences

Surico, Paolo - 2002

This paper investigates the empirical relevance of a new framework for monetary policyanalysis in which decision makers are allowed to weight differently positive and negative deviations of inflation and output from the target values. The specification of the central bank objective is general...

Prediction problem for target events based on the inter-event waiting time

Shapoval, A. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 22, pp. 5145-5154

In this paper we address the problem of forecasting the target events of a time series given the distribution ξ of time gaps between target events. Strong earthquakes and stock market crashes are the two types of such events that we are focusing on. In the series of earthquakes, as McCann...

Inference for Weibull distribution under generalized order statistics

Aboeleneen, Z.A. - In: Mathematics and Computers in Simulation (MATCOM) 81 (2010) 1, pp. 26-36

Based on generalized order statistics from Weibull distribution the approach of Bayesian and non-Bayesian estimation are discussed. We present a simple and efficient simulational algorithm for generating a generalized order statistics sample from any continuous distribution. Specializations to...

Evaluating German business cycle forecasts under an asymmetric loss function

Döpke, Jörg; Fritsche, Ulrich; Siliverstovs, Boriss - In: OECD Journal: Journal of Business Cycle Measurement and … 2010 (2010) 1, pp. 1-18

different forecasts per year, we test for a possible asymmetry of the forecasters’ loss function and estimate the degree of … of the forecasts under the assumption of a possibly asymmetric loss function and for the features of an optimal forecast … under the assumption of a generalised loss function. We find evidence of the existence of an asymmetric loss function of …
