The consequences of deregulation for economic statistics are discussed with a view to Europe 1992. In particular, the effects of the introduction of the Intrastat-system for statistics on international trade are investigated. It is argued that if the Statistical Offices of the EC-countries do no...

In this paper, concepts of income are discussed in view of the purpose of use and the actual circumstances. Main choices in defining income are presented in a general system. The national accounts is a multi-purpose framework. It should therefore contain several concepts of income.

A high degree of multicollinearity among the explanatory variables severely impairs estimation of regression coefficients by the Ordinary Least Squares. Several methods have been suggested to ameliorate the deleterious effects of multicollinearity. In this paper we aim at comparing the...

From a conceptual point of view, for most purposes net figures of Domestic Product and National Income are to be preferred to gross figures. Nevertheless, in practice gross figures are most often used on the ground of various arguments. In this paper, these arguments are challenged. To this end,...

Research is an original contribution to the existing stock of knowledge and it is a powerful tool for knowledge generation. A newly born nation Eritrea has been facing number of challenges in research and development particularly the challenge of applying knowledge to work in the economy....

Since attrition in the European Community Household Panel (ECHP) has cumulated to a considerable extent, there is concern that attrition biases empirical analysis. In this paper we compare the performance of four different strategies for estimating an earnings equation in the presence of panel...

Existing hedonic methods cannot be easily adapted to estimate willingness to pay for product characteristics when willingness to pay depends on a very large basket of goods. We show how to marry these methods with revealed preference arguments to estimate bounds on willingness to pay using data...

It is well known that in a vector autoregressive (VAR) model Granger non-causality is characterized by a set of restrictions on the VAR coefficients. This characterization has been derived under the assumption of non-singularity of the covariance matrix of the innovations. This note shows that...

The method of instrumental variables (IV) and the generalized method of moments (GMM), and their applications to the estimation of errors-in-variables and simultaneous equations models in econometrics, require data on a sufficient number of instrumental variables that are both exogenous and...
