Corporate R&D and Firm Efficiency: Evidence from Europe’s Top R&D Investors
Kumbhakar, Subal C.; Ortega-Argilés, Raquel; Potters, … - Institute for the Study of Labor (IZA) - 2009
The main objective of this study is to investigate the impact of corporate R&D activities on firms' performance, measured by labour productivity. To this end, the stochastic frontier technique is applied, basing the analysis on a unique unbalanced longitudinal dataset consisting of 532 top...

When, Where and How to Perform Efficiency Estimation
Badunenko, Oleg; Henderson, Daniel J.; Kumbhakar, Subal C. - Institute for the Study of Labor (IZA) - 2011
In this paper we compare two flexible estimators of technical efficiency in a cross-sectional setting: the nonparametric kernel SFA estimator of Fan, Li and Weersink (1996) to the nonparametric bias corrected DEA estimator of Kneip, Simar and Wilson (2008). We assess the finite sample...

Redistribution Policy and Inequality Reduction in OECD Countries: What Has Changed in Two Decades?
Immervoll, Herwig; Richardson, Linda - Institute for the Study of Labor (IZA) - 2011
We use a range of data sources to assess if, and to what extent, government redistribution policies have slowed or … redistribution systems in place, greater inequality automatically leads to more redistribution, even if no policy action is taken. We … redistribution. Between the mid-1990s and the mid-2000s, the redistributive strength of tax-benefit systems then weakened in many …

Household Incomes and Redistribution in the European Union: Quantifying the Equalising Properties of Taxes and Benefits
Immervoll, Herwig; Levy, Horacio; Lietz, Christine; … - Institute for the Study of Labor (IZA) - 2005
The systems of direct taxes and cash benefits in the Member States of the European Union vary considerably in size and structure. We explore their direct impacts on cross-sectional income inequality (termed "redistributive effect" for the purpose of this paper) using EUROMOD, a tax-benefit...

Social Spending Generosity and Income Inequality: A Dynamic Panel Approach
Niehues, Judith - Institute for the Study of Labor (IZA) - 2010
This paper explores if more generous social spending polices in fact lead to less income inequality, or if redistributive outcomes are offset by behavioral disincentive effects. To account for the inherent endogeneity of social policies with regard to inequality levels, I apply the System GMM...

Are Intellectual Property Rights Unfair?
Saint-Paul, Gilles - Institute for the Study of Labor (IZA) - 2002
If redistribution is distortionary, and if the income of skilled workers is due to knowledgeintensive activities and … reduction reduces statis inefficiency. On the other hand, standard redistribution also reduces the level of R and D because it … that standard redistribution always dominates limitations to IPRs. …

Traits, Imitation, and Evolutionary Dynamics
Schnedler, Wendelin - Institute for the Study of Labor (IZA) - 2003
In this article, a modelling framework for the information transmission between agents in an evolutionary game setting is proposed. Agents observe traits which reflect past and present behaviour and success of other agents. If agents imitate more successful agents based on these traits, the...

Calculating Confidence Intervals for Continuous and Discontinuous Functions of Estimated Parameters
Ham, John C.; Woutersen, Tiemen - Institute for the Study of Labor (IZA) - 2011
The delta method is commonly used to calculate confidence intervals of functions of estimated parameters that are differentiable with non-zero, bounded derivatives. When the delta method is inappropriate, researchers usually first use a bootstrap procedure where they i) repeatedly take a draw...
