After 1950`s, gradually the variable of human capital was included in the economic growth analysis .Foreign trade has also provided economic growth. Among other variables, which can be effective on the economic growth, are the country's economic and political structure and history of the oil or socialist system. The aim of this study was to analyze the effect of human capital, foreign trade, ha...

Several variants of a first-order simplification rule for nonnormal form tableaux using syntactic constraints are presented. These can be used as a framework for porting methods like unit resolution or hyper tableaux to non-normal form free variable tableaux.

An alternative approach to the semantics of definite descriptions was proposed by Heim in her dissertation [1982]. Heim assigns to pragmatics a larger part of the task of specifying the meaning of definite descriptions than the neo-Russellians do. In Heim’s theory, definite and indefinite NPs are semantically equivalent, and both introduce free variables. The truth conditions proposed by Heim f...

This thesis consists of three essays: Essay Nr. 1 (Kolmogorov-Wiener Filters for Finite Time-Series) describes a framework to implement optimally linear filters in the context of finite time series. The filters under consideration have the property that they minimize the mean squared error compared to some ideal hypothetical filter. It is shown in examples that three commonly used filters, the ...

For forecasting and economic analysis many variables are used in logarithms (logs). In time series analysis this transformation is often considered to stabilize the variance of a series. We investigate under which conditions taking logs is beneficial for forecasting. Forecasts based on the original series are compared to forecasts based on logs. It is found that it depends on the data generatio...

Waves of globalization reflect the historical technical progress and modern economic growth. The dynamics of this process are here approached using the multidimensional scaling (MDS) methodology to analyze the evolution of GDP per capita, international trade openness, life expectancy, and education tertiary enrollment in 14 countries. MDS provides the appropriate theoretical concepts and the ex...

At the least sophisticated level of economic theory lies the belief that certain pairs of economic variables should not diverge from each other by too great an extent, at least in the long-run. Thus, such variables may drift apart in the short-run or according to seasonal factors, but if they continue to be too far apart in the long-run, then economic forces, such as a market mechanism or gover...

The attempt is made in this discussion to describe and draw lessons from the treatment of behavioral demographic variables in the Bachue demo-economic models constructed for the Philippines, Kenya, Brazil and Yugoslavia. Focus is on certain theoretical, technical and practical problems encountered in inserting demographic variables in the system as a whole; how they have been measured in the v...
