(Spatial) panel data are routinely modelled in discrete time (DT). However, there are compelling arguments for continuous time (CT) modelling of (spatial) panel data. Particularly, most social processes evolve in CT, so that statistical analysis in DT is an oversimplification, gives an...

Total Factor Productivity (TFP)is often used on the macro-economic level as an indicator of changes in efficiency of a country. In many transition economies TFP is seen to have been negative the last decade of the plan economy and starts increasing and become positive after a (quite a) few years...

This paper resulted in a publication in the <I>Journal of Econometrics</I> (2014). Volume 180, pages 127-140.<P> An exact maximum likelihood method is developed for the estimation of parameters in a nonlinear non-Gaussian dynamic panel data model with unobserved random individual-specific and time-varying...</p></i>

This paper introduces a new estimator for the fixed effects dynamic panel data model withexogenous variables. This estimator does not share some of the drawbacks of recently developed IVand GMM estimators and has a good performance even in small samples. The nearly unbiased estimatoris derived...

This paper examines the effect of a housing assistance program on school enrollment, child labor and poverty reduction among poor families in Ecuador. Administrative data is merged to a household panel to link the history of a voucher application with socioeconomic information. Two empirical...

To study the effect of the euro on international goods trade one typically estimates a panel model for the level of trade. Trade levels increase over time, and we show that this is not fully explained by the included regressors. Because the euro is only present at the end of the sample, this may...

For refuse collection, we estimate the cost effects of different institutional modes using panel data for almost all Dutch municipalities between 1998 and 2010. The modes we consider are private contracts, intermunicipal cooperation, public provision and own collection. For private companies,...

Psychologists and sociologists usually interpret answers to happiness surveys as cardinal and comparableacross respondents (Kahneman et al. 1999). As a result, these social scientists run OLS regressionson happiness and changes in happiness. Economists, on the other hand, usually only assume...
