Nonparametric estimation and testing of interaction in additive models
Sperlich, Stefan; Tjostheim, Dag; Yang, Lijian - 1998
We consider an additive model with second order interaction terms. It is shown how the components of this model can be estimated using marginal integration, and the asymptotic distribution of the estimators is derived. Moreover, two test statistics for testing the presence of interactions are...

On estimation of monotone and concave frontier functions
Gijbels, Irène; Mammen, Enno; Park, Byeong U.; Simar, … - 1998
When analyzing the productivity of firms, one may want to compare how the firms transform a set of inputs x (typically …

The empirical determinants of the Euro : short and long run perspectives
Chinn, Menzie David - 2000
is provided by a productivity-based model of the real value of the euro. Some panel regression estimates of the … relationship between intercountry relative productivity differentials and real exchange rates is presented. Using these estimates … to conduct some calculations, one comes to the conclusion that unless drastic changes to productivity trends occur, there …

Quantile-VaR is the wrong measure to quantify market risk for regulatory purposes
Jaschke, Stefan R. - 2001
Starting from the objective of banking supervision - to minimize the overall costs of banking to the general public - we show that the current standard of quantifying market risk is flawed. It is perfectly aligned with the interests of banks' shareholders and management, but not with the...

The Cornish-Fisher-Expansion in the context of Delta - Gamma - Normal approximations
Jaschke, Stefan R. - 2001
Qualitative and quantitative properties of the Cornish-Fisher-Expansion in the context of Delta-Gamma-Normal approaches to the computation of Value at Risk are presented. Some qualitative deficiencies of the Cornish-Fisher-Expansion - the monotonicity of the distribution function as well as...

The great demand depression
Weder, Mark - 2001
This paper entertains the notion that disturbances on the demand side play a central role in our understanding of the Great Depression. In fact, from Euler equation residuals we are able to identify a series of unusually large negative demand shocks that appeared to have hit the U. S. economy...

Semiparametric estimation in single index poisson regression : a practical approach
Climov, Daniela; Delecroix, Michel; Simar, Léopold - 2001
In a single index Poisson regression model with unknown link function, the index parameter can be root-n consistently estimated by the method of pseudo maximumum likelihood. In this paper, we study, by simulation arguments, the practical validity of the asymptotic behavior of the pseudo maximum...

Fractional integration and business cycle features
Candelon, Bertrand; Gil-Alaña, Luis A. - 2001
We show in this article that fractionally integrated univariate models for GDP may lead to a better replication of business cycle characteristics. We firstly show that the business cycle features are clearly affected by the degree of integration as well as by the other short run components of...

Experimental "beauty contests" with homogeneous and heterogeneous players and with interior and boundary equilibria
Güth, Werner; Kocher, Martin; Sutter, Matthias - 2001
We study behavior in experimental beauty contests with, first, boundary and interior equilibria, and, second, homogeneous and heterogenous types of players. We find quicker and better convergence to the game-theoretic equilibrium with interior equilibria and homogeneous players. -- beauty...

Simultaneous over- and underconfidence : evidence from experimental asset markets
Maciejovsky, Boris; Kirchler, Erich - 2001
In this paper individual overconfidence within the context of an experimental asset market is investigated. Overall, 72 participants traded one risky asset on six markets of 12 participants each. The results indicate that individuals were not generally overconfident. Moreover, overconfidence was...
