A transition economy or transitional economy is an economy which is changing from a centrally planned economy to a market economy. Transition economies undergo a set of structural transformations intended to develop market-based institutions. These include economic liberalization, where prices are set by market forces rather than by a central planning organization. In addition to this trade barriers are removed, there is a push to privatize state-owned enterprises and resources, state and collectively run enterprises are restructured as businesses, and a financial sector is created to facilitate macroeconomic stabilization and the movement of private capital. The process has been applied in China, the former Soviet Union and Eastern bloc countries of Europe and some Third world countries, and detailed work has been undertaken on its economic and social effects.
The transition process is usually characterized by the changing and creating of institutions, particularly private enterprises; changes in the role of the state, thereby, the creation of fundamentally different governmental institutions and the promotion of private-owned enterprises, markets and independent financial institutions. In essence, one transition mode is the functional restructuring of state institutions from being a provider of growth to an enabler, with the private sector its engine. Another transition mode is change the way that economy grows and practice mode. The relationships between these two transition modes are micro and macro, partial and whole. The truly transition economics should include both the micro transition and macro transition. Due to the different initial conditions during the emerging process of the transition from planned economics to market economics, countries uses different transition model. Countries like P.R.China and Vietnam adopted a gradual transition mode, however Russia and some other East-European countries, such as the former Socialist Republic of Yugoslavia, used a more aggressive and quicker paced model of transition.The term "transition period" is also used to describe the process of transition from capitalism to the first stage of socialism, preceding the establishment of fully developed socialism (aka communism).
I noticed that when I was younger, there was a much higher prevalence of bands having popular songs. I'm talking about the late 90s to about 2004. It seems in recent times that music have shifted towards solo artists instead of bands, I was wondering what might account for this.
I know that the nucleus can be considered a bunch of particles that constantly transition between protons and neutrons due to exchange. Given that, is it meaningful to talk about the "average" time that a nucleon spends as either a proton or a neutron before switching to the other? Or is that a...
