Competition and innovation in automobile markets
Ghosal, Vivek; Ni, Jiayao - 2015
Using data from the US automobile market, we empirically examine the link between competition and innovation. Consistent with a large literature, we use patent counts as a measure of innovation. The combination of the US market's economic importance, market dynamics, and the significant...

Exponential time trends in a fractional integration model
Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2023
This paper introduces a new modelling approach that incorporates nonlinear, exponential deterministic terms into a fractional integration model. The proposed model is based on a specific version of Robinson's (1994) tests and is more general that standard time series models, which only allow for...

The effects of cash for clunkers on local air quality
Helm, Ines; Koch, Nikolas; Rohlf, Alexander - 2023
We study the effects of a large car scrappage scheme in Germany on new car purchases and local air quality by combining vehicle registration data with data on local air pollutant emissions. For identification we exploit cross-sectional variation across districts in the number of cars eligible...

Policy-induced innovation in clean technologies : evidence from the car market
Rozendaal, Rik L.; Vollebergh, Herman R. J. - 2021
This article tests the effects of fuel economy and greenhouse gas emission standards on the direction of innovation, in particular on breakthrough technologies in the automotive industry. We develop an intuitive measure of standard stringency that captures the policy's most important features...

Identification and estimation of heterogeneous agent models : a likelihood approach
Parra-Alvarez, Juan Carlos; Posch, Olaf; Wang, Mu-Chun - 2017
In this paper, we study the statistical properties of heterogeneous agent models with incomplete markets. Using a Bewley-Hugget-Aiyagari model we compute the equilibrium density function of wealth and show how it can be used for likelihood inference. We investigate the identifiability of the...

Small sample properties of maximum likelihood versus generalized method of moments based tests for spatially autocorrelated errors
Egger, Peter; Larch, Mario; Pfaffermayr, Michael; … - 2005
This paper undertakes a Monte Carlo study to compare MLE-based and GMM-based tests regarding the spatial autocorrelation coefficient of the error term in a Cliff and Ord type model. The main finding is that a Wald-test based on GMM estimation as derived by Kelejian and Prucha (2005a) performs...

Optimal policy and network effects for the deployment of zero emission vehicles
Meunier, Guy; Ponssard, Jean-Pierre - 2018
We analyze the impact of indirect network effects in the deployment of zero emission vehicles in a static partial equilibrium model. In most theoretical analysis direct and indirect effects are conflated, and relatively few authors have explicitly considered indirect network effects. We also...
