This talk will discuss the use of a number of Stata commands, some "official" and some user-contributed, in the context of working with time-series and panel data. Testing for endogeneity/exogeneity of regressors, heteroskedasticity in an instrumental variables context, and fitting regression...

This paper proposes a simultaneous-equation approach to the estimation of the contribution of transport infrastructure accumulation to regional growth. We model explicitly the political-economy process driving infrastructure investments; in doing so, we eliminate a potential source of bias in...

This paper proposes a simultaneous-equation approach to the estimation of the contribution of infrastructure accumulation to private production. A political-economy model for the allocation of public infrastructure investment grants is formulated. Our empirical findings, using a panel of large...

This paper describes the different institutional frameworks for infrastructure policy in Germany and France. The economic effects of infrastructure are estimated econometrically for German and French regions. We find evidence that regional road infrastructure has a significant impact on regional...

This paper uses a partial adjustment approach to measure the contribution of public infrastructure to local private production. In the first step of the empirical analysis we apply a principal component analysis in order to construct 2 new infrastructure indicators from an array of 7 measures of...

Using time-series cross-section data from the manufacturing sector of the 11 Bundesländer from 1970 to 1993, we examine the impact of road infrastructure on private production applying three different approaches; i.e., a Cobb-Douglas production function, a translog production function and a...

In this paper, we investigate the link between optimal level of leverage and macroeconomic uncertainty. Using the model of firm's value maximization, we show that as macroeconomic uncertainty increases, captured by an increase in the variability of industrial production or inflation, firms...

This paper describes the different institutional frameworks for planning and financing of infrastructure in Germany and France. Furthermore, the economic effects of infrastructure are estimated econometrically for German and French regions. We find evidence, that regional road infrastructure has...
