This paper applies an established bid-ask spread decomposition model to spot foreign exchange market in order to assess the impact of European Monetary Union (EMU). Additionally, the paper presents and tests a modified decomposition model which is specifically adapted to the features of order-driven markets. The latter model provides much improved performance. Price clustering is introduced as ...

Diffuse competition due to niche overlap between actors without (direct) ties with each other, constrains their structural autonomy. This is not dealt with in Burt’s mathematical model of his well-known structural holes theory. We fix his model by introducing a network measure of niche overlap. © 2002 Elsevier Science B.V.

In this paper we apply the method of inferred causation for macroeconomic analysis. First we introduce briefly the theory of inferred causation developed by Pearl and Verma (1991). We apply this method to the identification of structural vector autoregression (SVAR) models. In an example of monetary policy analysis we demonstrate how causal information embedded in the data can be used to identi...

We quantify the role of population aging in structural transformation process. Household-level data from United States show that fraction expenditures devoted to services increases with household age. use a shift-share decomposition and quantitative model US accounted for about fifth observed increase service share consumption between 1982 2016. The contribution rise is same size as real income...

The authors describe the principal results obtained from a new method applied to the estimation of potential U.S. GDP. This method derives from the work of Rennison (2002), which suggests that the joint use of extended multivariate filters and structural vector autoregression models is optimal for estimating potential output. The authors use this approach to estimate the two components of poten...

The German Economy is not only affected by the Unification of Germany but by a significant influx of immigrants from abroad and huge migration from East to West Germany around the date of unification. Data from the German Socio-Economic Panel Study (GSOEP) allows to disentangle those effects by decomposition of the Theil I (0)-Index of inequality. In addition, the paper offers insights in the t...

Wage Differentials, Discrimination and Inequality: A Cautionary Note on the Juhn, Murphy and Pierce Decomposition Method This paper shows how difficult it is to study the roles of discrimination and unobserved skills when studying changes in racial and gender wage gaps over time by examining merits and shortcomings of a popular decomposition method by Juhn, Murphy and Pierce (1991). The JMP met...

This note demonstrates how performance measure congruity and noise determine an agency’s total surplus within an linear agency framework with multiple tasks. It provides a decomposition of agency costs, leading back to a congruity index previously proposed in the literature. In addition, it generalizes this index to a more general cost function, thereby highlighting the context specificity of t...

abstract this paper proposes an approach to find an optimum structure for educational levels of human forces. to this end, a linear programming (lp) model integrated with a social accounting matrix (sam) was employed. the integrated model was employed using the sam of golestan province of iran. it was demonstrated that when unemployment is the result of inconsistency between supply and demand f...

This paper presents an innovative approach to model validation for a structure with significant parameter variations. Model uncertainty of the structural dynamics is quantified with the use of a singular value decomposition technique to extract the principal components of parameter change, and an interval model is generated to represent the system with parameter uncertainty. The coordinate vect...
