Upward Pricing Pressure of Mergers Weakening Vertical Relationships

Langus, Gregor - 2016

We modify the UPP test of Farrell and Shapiro (2010) to take into account the possibility that a merger weakens (or … eliminates) a vertical supply relationship. After deriving a general effect of the merger, we provide an example of simple …

Price or Variety? An Evaluation of Mergers Effects in Grocery Retailing

Argentesi, Elena - 2018

claim by studying the effect of a national merger between two large Dutch supermarket chains on prices and on the depth as … merger's effects, controlling for selection on observables when defining our control group through a matching procedure. We … show that the local change in competitive conditions due to the merger did not affect individual products' prices but it …

Heterogeneous Merger Impacts on Competitive Outcomes

Siebert, Ralph - 2017

differential merger outcomes are caused mostly by firms' technology or product market attributes. Furthermore, empirical merger …. We allow the merger responses to vary across firms, even after controlling for regressors, and apply a random …

Accuracy and Efficiency of Various GMM Inference Techniques in Dynamic Micro Panel Data Models

Kiviet, Jan Frederik; Pleus, Milan; Poldermans, Rutger - CESifo - 2015

The performance in finite samples is examined of inference obtained by variants of the Arellano-Bond and the Blundell-Bond GMM estimation techniques for single dynamic panel data models with possibly endogenous regressors and cross-sectional heteroskedasticity. By simulation the effects are...

Transformed Maximum Likelihood Estimation of Short Dynamic Panel Data Models with Interactive Effects

Hayakawa, Kazuhiko; Pesaran, M. Hashem; Smith, L. Vanessa - CESifo - 2014

This paper proposes the transformed maximum likelihood estimator for short dynamic panel data models with interactive fixed effects, and provides an extension of Hsiao et al. (2002) that allows for a multifactor error structure. This is an important extension since it retains the advantages of...

Natural Resources: Curse or Blessing?

Ploeg, Frederick Van der - CESifo - 2010

Are natural resources a “curse” or a “blessing”? The empirical evidence suggests either outcome is possible. The paper surveys a variety of hypotheses and supporting evidence for why some countries benefit and others lose from the presence of natural resources. These include that a...

Testing Weak Cross-Sectional Dependence in Large Panels

Pesaran, M. Hashem - CESifo - 2012

This paper considers testing the hypothesis that errors in a panel data model are weakly Cross-sectionally dependent (CD), using the exponent of cross-sectional dependence introduced recently in Bailey, Kapetanios and Pesaran (2012). It is shown that the implicit null of the CD test depends on...

Robust Standard Errors in Transformed Likelihood Estimation of Dynamic Panel Data Models

Hayakawa, Kazuhiko; Pesaran, M. Hashem - CESifo - 2012

This paper extends the transformed maximum likelihood approach for estimation of dynamic panel data models by Hsiao, Pesaran, and Tahmiscioglu (2002) to the case where the errors are cross-sectionally heteroskedastic. This extension is not trivial due to the incidental parameters problem that...

On the Finite Sample Properties of Pre-Test Estimators of Spatial Models

Piras, Gianfranco; Prucha, Ingmar R. - CESifo - 2014

This paper explores the properties of pre-test strategies in estimating a linear Cliff-Ord-type spatial model when the researcher is unsure about the nature of the spatial dependence. More specifically, the paper explores the finite sample properties of the pre-test estimators introduced in...
