In simultaneous equation models the two stage least squares (2SLS) estimator of the coefficients, though consistent, is biased in general and the nature of this bias has given rise to a good deal of research. However, little if any attention has been given to the bias that arises when an...

Asymptotic expansions are employed in a dynamic regression model with a unit root in order to find approximations for the bias, the variance and for the mean squared error of the least-squares estimator. For this purpose such expansions are shown to be useful only when the autoregressive model...

An approximation to order T-2 is obtained for the bias of the least-squares estimator in the stationary ARX model which yields generalisations of Kendall's and White's classic results for particular variants of AR(1) models. The results show that generally the second-order approximation is...

New trade theory suggests that improvements in the variety and quality of products may be as important as price competitiveness as an explanation of trade flows. This paper tests this proposition for export volumes for the G7 using relative cumulated investment as a proxy for innovation....

The paper examines asymptotic expansions for estimation errors expressed explicitly as functions of unferlying random variables. Taylor series expansions are obtained from which first and secomd moment approximationc are derived. While the expansions are essentially equivalent to the traditional...

This paper analyses the correlation between social security budget and the main macroeconomic indicators (like GDP, monthly average gross earnings, unemployment) in Romania during the period 2000 – 2009. Romania faces a more severe economic recession than originally anticipated. Although the...

This paper considers the impact of changes in the payment discipline of governments on the private sector. We argue that increased delays in public payments can affect private sector liquidity and profits and hence ultimately economic growth. We test this prediction empirically for European...

This study aims at identifying the factors affecting the customers demand for Internet banking usage by analyzing sample of 450 consumers‘ responses who have been interviewed the private, public and foreign banks which included ICICI Bank Ltd., HDFC Bank Ltd. and AXIS Bank, Standard Chartered...

This paper describes a methodology elaborated for forecasting the volume of postal services on the basis of statistical methods of regression analysis on the example of the Republic of Komi. The influence of internal and external factors on the market of postal money orders of the Republic is...

The analysis of financial economic ratios provides managers and external partners feedback on the results obtained from operational activities and the associated performance and risks. This paper studies the functional dependence of the companies’ success (on performance) over internal...
