We investigate the solar wind energy flux in inner heliosphere using 12-day observations around each perihelion of Encounter One (E01), Two (E02), Four (E04), and Five (E05) Parker Solar Probe (PSP), respectively, with a minimum heliocentric distance 27.8 radii ($R_\odot{}$). Energy was calculated based on electron parameters (density $n_e$, core temperature $T_{c}$, suprathermal $T_{h}$) obtai...

The economic constitutions of Germany and Greece have resulted in the postwar period in two economies that are based on two vastly different philosophies. Germany has built a highly competitive, outward looking economy based essentially on the principles of the so-called “Social Market Economy”, whereas Greece has set up a “state-managed economy” by drawing on the principles of central planning...

This article adds technology choice to a free-entry Cournot model with linear demand and constant marginal costs. Firms can choose from a discrete set of technologies. This simple framework yields non-existence of equilibrium, existence of multiple equilibria and equilibria in which ex-ante identical ̄rms choose di®erent technologies as possible outcomes. I provide a full characterization of th...

This study probed the macroeconomic effects of budget deficit in Nigeria. Specifically, it seeks to probe effect on private investment and public Nigeria by adopting ADF unit root test ARDL model, Granger Causality short-run diagnostics stability using annual time series data covering 37 years from 1981 2019. The variables employed include – Growth rate real gross domestic product, (Gross Fixed...

researches in exploring of driving forces of regional endogenous development, concentrate on subjects which have been so controversial. regional endogenous development (red), together with other core regional development concepts, is usually focused on the sub-national regional development process of the home country. this paper attempts to conceptualize and examine regional endogenous developm...
