Macroeconomic Effects and Policy Challenges of Population Aging
Faruqee, Hamid; Tamirisa, Natalia T. - International Monetary Fund (IMF) - 2006
This paper simulates the macroeconomic effects of population aging in a dynamic overlapping generations model of a … small open economy. The model is calibrated to data for the Czech Republic, where population aging is proceeding at a pace … comparable to that in other advanced countries in Europe. Simulations show that population aging is likely to slow economic …

Population Aging in Japan; Demographic Shock and Fiscal Sustainability
Mühleisen, Martin; Faruqee, Hamid - International Monetary Fund (IMF) - 2001
The paper develops a general equilibrium framework to examine the economic implications of population aging in Japan … assess the impact of aging on Japan's government finances; and (ii) compare fiscal policy options with respect to their … implications of population aging in Japan. Particular attention is paid to aggregate saving behavior which is modeled on the basis …

A Forecast Model of Hydrologic Single Element Medium and Long-Period Based on Rough Set Theory
Dong, Si-Hui; Zhou, Hui-Cheng; Xu, Hai-Jun - In: Water Resources Management 18 (2004) 5, pp. 483-495
On the basis of rough set theory, this paper presents the single element medium- and long-term classification forecast model that uses historical data of a hydrologic series as forecast factors. The minimal rule set, i.e., forecast pattern set, is achieved according to the principle of maximal...

Combining term structure of interest rate forecasts: The Brazilian case
Araújo, Rafael Cavalcanti de; Cajueiro, Daniel Oliveira - In: Economia 14 (2013) 2, pp. 102-121
Issues like structural breaks and misspecification biases make it difficult to find a term structure of interest rates forecast model that dominates all competitors. Focusing on Brazilian data, this paper aims to identify the existence of combining methods that provide superior performance than...

Resilience Assessment of Lowland Plantations Using an Ecosystem Modeling Approach
Wu, Chia-Hsin; Lo, Yueh-Hsin; Blanco, Juan A.; Chang, … - In: Sustainability 7 (2015) 4, pp. 3801-3822
As afforestation programs of former farmlands take hold in Taiwan to achieve a variety of ecological and socio-economic values, it is becoming necessary to define best forest management. Hence, we simulated mixed stands of <i>Cinnamomum camphora </i>and <i>Fraxinus griffithii</i> planted through a gradient of...
