title: Simulations of voivodeship and oblast development trajectories. An analysis based on the gravity growth model
abstract: The purpose of this chapter is to analyze the determinants of the spatial diversity of labor productivity (materializing technical progress) in Poland and Ukraine in terms of administrative regions. The theoretical basis for this empirical analysis was the gravitational economic growth model, which was an extension of the Solow economic growth model. The basic assumption of the model is that labor productivity in Polish voivodeships and Ukrainian oblasts depends on the capital employed, that is,
