This paper focuses on the empirical link between monetary policy transparency and output volatility. Key questions addressed are: (i) Does transparency about policy processes stabilize output? (ii) Whether different aspects of transparency differ qualitatively or quantitatively in terms of their...

Motivated by the first-differencing method for linear panel data models, we propose a class of iterative local polynomial estimators for nonparametric dynamic panel data models with or without exogenous regressors. The estimators utilize the additive structure of the first-differenced...

Determinar la relación entre las tasas de cobertura de acueducto y alcantarillado y la calidad del agua con la mortalidad infantil es clave para el diseño de políticas públicas que buscan mejorar las condiciones de vida de la población. El presente estudio encuentra que –para el caso de...

The German reserve power market was subject to important regulatory changes in recent years. A new market design was created by synchronization and interconnection of the four control areas. In this paper, we analyze whether or not the reforms led to lower prices for minute reserve power (MRP)....

We highlight the fact that the Sargan-Hansen test for GMM estimators applied to panel data is a joint test of valid orthogonality conditions and coefficient stability over time. A possible reason why the null hypothesis of valid orthogonality conditions is rejected is therefore that the slope...

While several studies have examined the effect of Foreign Direct Investment (FDI) on economic development indicators, most of these studies focused on economic growth with very little attention paid to health outcomes. Moreover, among the studies that took account of health outcomes, none of...

This paper introduces a panel GMM framework for identifying and estimating demand elasticities via heteroscedasticity. While existing panel estimators address the simultaneity problem, the state-ofthe-art Feenstra/Soderbery (F/S) estimator suffers from inconsistency, inefficiency, and lacks a...

The problem of instrument proliferation and its consequences (overfitting of endogenous variables, bias of estimates, weakening of Sargan/Hansen test) are well known. The literature provides little guidance on how many instruments is too many. It is common practice to report the instrument count...

We study some recent developments and challenges in the empirics of the effects of social networks. We focus in particular on researchers’ ability to make policy recommendations based on a standard linear econometric model. We examine the potential compatibility between this type of...

I discuss instrumental variable estimates of the effect of providing unpaid adult care on the caregivers' probability of being employed, using eight waves of the European Community Household Panel. I focus on men aged 40–64 and women aged 40–59 from thirteen Member States, aggregated in two...
