The Real Effect of Financial Crises in the European Transition Economies

2010

Working Paper GATE 2009-20; International audience; The aim of this work is to assess the impact of financial crises on output for 11 European transition economies (CEECs). The results suggest that financial crises have a significant and permanent effect, lowering long-term output by about 17 percent. The effect is more important in smaller countries, with relative higher dependence on external financing, and in which the banking sector noticed more important financial disequilibria. We also found that fiscal policy measures have been the most efficient tools in dealing with the crises, while the role of monetary policy instruments has been rather blinded. Exchange rate resulted to be more …

Approximate convex hull of affine iterated function system attractors

2012

International audience; In this paper, we present an algorithm to construct an approximate convex hull of the attractors of an affine iterated function system (IFS). We construct a sequence of convex hull approximations for any required precision using the self-similarity property of the attractor in order to optimize calculations. Due to the affine properties of IFS transformations, the number of points considered in the construction is reduced. The time complexity of our algorithm is a linear function of the number of iterations and the number of points in the output convex hull. The number of iterations and the execution time increases logarithmically with increasing accuracy. In additio…

The Asynchronous Leontief Model

1992

International audience; The traditional dynamic Leontief model is synchronous: every vertex acts simultaneously. A model with delays of action has been proposed, but it still remains synchronous. In this paper we propose an asynchronous version of the model that allows realistic computations. We fiurnish an algorithm and a program.

A distributed model for continuous-wave erbium-doped fiber laser

2011

Abstract A distributed model of a continuous-wave erbium-doped fiber laser is discussed. The model is based on two contra-propagated traveling laser waves, and includes inhomogeneous pumping, excited state absorption at the pump and the laser wavelengths, amplified spontaneous emission and radial distribution of populations of erbium levels. It is shown that excited state absorption is a main limiting factor to the laser's efficiency. Moreover, consideration of radial distributions of erbium levels' populations in the model reduces laser efficiency and decreases optimal reflection of the laser output coupler. The modeling results are in excellent agreement with the experimental study on the…

Input-Output Feedback Linearization Control of a Linear Induction Motor Taking Into Consideration Its Dynamic End-Effects and Iron Losses

2020

This article proposes a new input-output feedback linearization control (FLC) technique of linear induction motors (LIMs), taking into consideration both the dynamic end-effects and the iron losses. Starting from a previously conceived dynamic model, including the dynamic end-effects and the iron losses, all the theoretical framework of the FLC has been developed. The proposed FLC improves a previous version of FLC in accounting also the iron losses, which in LIMs with fixed-secondary sheet play a pivotal role more than in rotating induction motors (RIMs). The proposed FLC has been experimentally tested on a suitably developed test setup, and experimental comparisons between the proposed FL…

Banking Crises and Short and Medium Term Output Losses in Emerging and Developing Countries: The Role of Structural and Policy Variables

2012

The aim of this paper is to assess the dynamic impact of banking crises on output for a panel of developing economies. Using an unbalanced panel of 159 countries from 1970 to 2006, the paper shows that banking crises produce significant output losses. Output losses are larger for relatively richer economies, characterized by a higher level of financial deepening and larger current account imbalances. Flexible exchange rates, fiscal and monetary policy, and liquidity support policies have been found to attenuate the effect of the crises. © 2012 Elsevier Ltd.

Using CHARM to Adjust for Cross-hauling: The Case of the Province of Hubei, China

2015

Data for the Chinese province of Hubei are used to assess the performance of Kronenberg's Cross-Hauling Adjusted Regionalization Method (CHARM), a method that takes explicit account of cross-hauling when constructing regional input–output tables. A key determinant of cross-hauling is held to be the heterogeneity of commodities, which is estimated using national data. However, contrary to the authors’ findings for Finland, CHARM does not generate reliable estimates of Hubei's sectoral exports, imports and volume of trade, although it is more successful in estimating sectoral supply multipliers. The poor simulations of regional trade are attributed to the fact that Hubei is a relatively small…

A new approach to modelling the input-output structure of regional economies using non-survey methods

2021

AbstractThis paper proposes a new approach to the regionalization of national input–output tables where suitable regional data are scarce and analysts are considering using location quotients (LQs). We focus on the FLQ formula, which frequently yields the best results of the pure LQ-based methods, and develop an enhanced way of implementing this approach. We use a modified cross-entropy (MCE) method, along with a regression model, to estimate values of the unknown parameter δ in the FLQ formula, specific to both region and country. An analysis of survey-based data for 16 South Korean regions reveals that the proposed FLQ+ approach yields more accurate estimates of both input coefficients an…

GDP clustering: A reappraisal

2012

Abstract This note explores clustering in cross country GDP per capita using recently developed model based clustering methods for panel data. Previous research characterizing the components of the overall distribution of output either use ad hoc methods, or methods which ignore/subvert the panel nature of the data. These new methods allow the characterization of the possible autoregressive relationship of output between time points. We show that traditional static clustering decade by decade gives mixed results regarding clustering over time, while the application of longitudinal mixtures presents three distinct clusters at all periods of time.

Two Great Banking Crises and Their Economic Impact Compared: Spain 1976/1977 and 2008

2017

The 1976/1977 crisis was the most severe in Spanish history, but the losses associated with the 2008 crisis are huge. This paper compares these two great banking crises and identifies the main parallels and differences between them. Is the current crisis as severe as that of 1976? What is the impact on the banking and financial sectors? We show that the 1976 crisis is being surpassed by the 2008 crisis in terms of the decline in GDP, industrial production and unemployment, and that these two events have had at least a similar impact in terms of output gap and output loss. Finally, the financial impact measured by different financial indicators confirms the greater severity of the 2008 crisi…
