This note explores the relationship between the price elasticity of demand and the R&D intensity of the product. We introduce the concept of R&D intensity into a standard Dixit-Stiglitz/Krugman-type setting. R&D activity is treated as a fixed cost of production. Within this framework, sectors...

Bandwidth selection and the estimation of treatment effects with unbalanced data

Galdo, Jose; Smith, Jeffrey A.; Black, Dan - 2007

This paper addresses the selection of smoothing parameters for estimating the average treatment effect on the treated using matching methods. Because precise estimation of the expected counterfactual is particularly important in regions containing the mass of the treated units, we define and...

Commuting, wages and bargaining power

Rupert, Peter; Stancanelli, Elena G. F.; Wasmer, Etienne - 2009

impact of commute time on job acceptance decisions. We also use the theory to calculate the bargaining power of workers which …A search model of the labor market is augmented to include commuting time to work. The theory posits that wages are … positively related to commute distance, by a factor itself depending negatively on the bargaining power of workers. Since not all …

Consistent estimation of the fixed effects ordered logit model

Baetschmann, Gregori; Staub, Kevin E.; Winkelmann, Rainer - 2011

The paper re-examines existing estimators for the panel data fixed effects ordered logit model, proposes a new one, and studies the sampling properties of these estimators in a series of Monte Carlo simulations. There are two main findings. First, we show that some of the estimators used in the...

Separability of Duration Dependence and Unobserved Heterogeneity

Turon, Hélène - 2003

Mixed proportional hazard models are commonly used to estimate duration dependence and unobserved heterogeneity in unemployment exit rates. Some strong assumptions are made in this framework, i.e. that the various influences on the individual unemployment exit rate are separable. The model we...

Do Bivariate SVAR Models with Long-Run Identifying Restrictions Yield Reliable Results? The Case of Germany

van Zandweghe, Willem; Gottschalk, Jan - 2001

Bivariate SVAR models employing long-run identifying restrictions are often used to investigate the source of business cycle fluctuations. Their advantage is the simplicity in use and interpretation. However, their low dimension may also lead to a failure of the identification procedure, with...

Generalized Selection Bias and the Decomposition of Wage Differentials

Yun, Myeong-Su - 1999

The major contribution of this paper is ending a new and flexible way to measure the effects of selection on log-wages. In this context, we offer a general approach to performing decomposition analysis when selection effects are present. We call the difference between unconditional and...

Decomposition Analysis for a Binary Choice Model

Yun, Myeong-Su - 2000

This paper introduces a new and simple decomposition method for a binary choice model that is equivalent to the Blinder-Oaxaca decomposition analysis for wage differentials. The decomposition method is first developed for a single probit model and later generalized to a simultaneous equations...

Pinning down the value of statistical life

Kniesner, Thomas J.; Viscusi, William Kip; Woock, … - 2007

Our research addresses fundamental long-standing concerns in the compensating wage differentials literature and its public policy implications: the econometric properties of estimates of the value of statistical life (VSL) and the wide range of such estimates from about $0.5 million to about $21...
