How credible are shrinking wage elasticities of married women labour supply?

Qin, Duo; Van Huellen, Sophie; Wang, Qing-chao - In: Econometrics : open access journal 4 (2016) 1, pp. 1-31

This paper delves into the well-known phenomenon of shrinking wage elasticities for married women in the US over recent decades. The results of a novel model experimental approach via sample data ordering unveil considerable heterogeneity across different wage groups. Yet, surprisingly constant...

Non-parametric estimation of intraday spot volatility : disentangling Instantaneous Trend and Seasonality

Vatter, Thibault; Wu, Hau-tieng; Chavez-Demoulin, Valérie - In: Econometrics : open access journal 3 (2015) 4, pp. 864-887

We provide a new framework for modeling trends and periodic patterns in high-frequency financial data. Seeking adaptivity to ever-changing market conditions, we enlarge the Fourier flexible form into a richer functional class: both our smooth trend and the seasonality are non-parametrically...

A one line derivation of EGARCH

McAleer, Michael; Hafner, Christian M. - In: Econometrics : open access journal 2 (2014) 2, pp. 92-97

parameters are not available under general conditions, but rather only for special cases under highly restrictive and … unverifiable conditions. It is often argued heuristically that the reason for the lack of general statistical properties arises … (2) the reason for the lack of statistical properties of the estimators of EGARCH under general conditions is that the …

Money Velocity and Asset Prices in the Euro Area

Dreger, Christian - 2009

Monetary growth in the euro area has exceeded its target since several years. At the same time, the money demand function seems to be increasingly unstable if more recent data are used. If the link between money balances and the macroeconomy is fragile, the rationale of monetary aggregates in...

M3 Money Demand and Excess Liquidity in the Euro Area

Dreger, Christian - 2008

Money growth in the euro area has exceeded its target since 2001. Likewise, recent empirical studies did not find evidence in favour of a stable long run money demand function. The equation appears to be increasingly unstable if more recent data are used. If the link between money balances and...

Monetary Policy Rules in Emerging Countries : Is There an Augmented Nonlinear Taylor Rule?

Caporale, Guglielmo Maria - 2016

This paper examines the Taylor rule in five emerging economies, namely Indonesia, Israel, South Korea, Thailand, and Turkey. In particular, it investigates whether monetary policy in these countries can be more accurately described by (i) an augmented rule including the exchange rate, as well as...

Outliers in semi-parametric estimation of treatment effects

Canavire-Bacarreza, Gustavo; Castro, Luis; Ontiveros, … - In: Econometrics : open access journal 9 (2021) 2, pp. 1-32

Outliers can be particularly hard to detect, creating bias and inconsistency in the semi-parametric estimates. In this paper, we use Monte Carlo simulations to demonstrate that semi-parametric methods, such as matching, are biased in the presence of outliers. Bad and good leverage point outliers...

Policy Evaluation of Waste Pricing Programs Using Heterogeneous Causal Effect Estimation

Valente, Marica - 2021

Using machine learning methods in a quasi-experimental setting, I study the heterogeneous effects of introducing waste prices - unit prices on household unsorted waste disposal - on waste demands and social welfare. First, using a unique panel of Italian municipalities with large variation in...
