In this next volume of Progress in Economics Research, chapters discuss the nexus between the volatilities of growth rates and crude oil; the growth effect of transportation investment; the economic impacts of a government default in stochastic overlapping generations model under homogeneous investor expectations; a new approach to the estimation of the total factor productivity dynamics and of the rate of disembodied technical change in the context of Cobb-Douglas production function with constant returns to scale; investment dynamics in Solow's Growth Model; financial performance and intellectual capital; financial integration, house price dynamics and saving rate divergence in an overlapping generations model with intra-EMU and Asian-U.S. trade imbalances; regional competitiveness within the cluster's territory; and the methodology and implementation of a knowledge management system in a polytechnic school.
