This paper investigates the link between the optimal level of non-financial firms' liquid assets and uncertainty. We develop a partial equilibrium model of precautionary demand for liquid assets showing that firms alter their liquidity ratio in response to changes in either macroeconomic or...

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 investigates the factors that explain the level of technical efficiency of a firm. In our empirical analysis, we use a unique sample of about 35,000 firms in 256 industries from the German Cost Structure Census over the years 1992-2004. We estimate the technical efficiency of the...

This paper explores the relationship between risk attitude and asset diversifcation in household portfolios. We first examine the impact of manifested risk aversion on the total number of distinct assets held in a portfolio (naive diversification). The second part of the paper focuses on a more...

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...
