The price diversification is a complex phenomenon. We show that price discrimination can have both positive and negative effects. The final result depends whether it makes competition more intense. As far as legal procedure is cocerned it is recommended to focus on the effects of compan's actions rather than on the form that these actions may take. There is a need to understand and distinguish between price discrimination as the...

This paper assesses the role played by country specific factors as determinants of exports' diversification process. Using a panel data-set for 60 countries and twenty years (1985-2004) we confirm that even after clearing out differences in income per capita, cross section variability in the degree of exports' diversification is significant. In general, apart from per capita income, variables influencing the size of accessible...

Low export diversification is a risk-augmenting factor for many countries dependent on natural resources. The literature tends to focus on the growth effects of resource dependence (‘resource curse’ debate) while not much is known on how it affects the variety of non-resource exports. To quantify this effect we decompose the relative Theil index using product-level export data from 160 countries over the time period 1996–2018....

Empirical findings confirm that relatively high specialisation of economic structures tends to be associated with low levels of income per capita, but countries diversify their export structures along their path of growth. However, usually only per capita income, and eventually, country-specific fixed effects are the sole explanatory variables taken into consideration in the estimation of specialisation curves. We extend the analysis...

An assessment of the effectiveness of investments is a key element of investment processes. In order to be comprehensive and exhaustive, it should go beyond the scope of the microeconomic assessment and take into account the macroeconomic calculation of effectiveness. The prerequisite for the effectiveness of investment decisions implemented by private companies is the maximization of the return on the investments. When attempting...
