Ragnar Nurkse and the Vicious Circle of Poverty

Why do some countries stay poor for generations, even when nothing obviously prevents them from investing their way to growth the way wealthier nations once did? Ragnar Nurkse's answer, published in 1953, was that poverty can be self-perpetuating in a way ordinary market logic does not automatically fix. A poor household or a poor country has little income left over after meeting basic needs, so it saves little; little saving means little capital for investment; little investment means productivity and income stay low, which brings the circle back to where it started. Nurkse called this the vicious circle of poverty, and it became one of the founding arguments for treating development economics as a field in its own right rather than a straightforward application of general equilibrium theory built around already-industrialized economies. If a poverty trap is real, escaping it is not simply a matter of removing obstacles and waiting for markets to clear; it can require a deliberate, coordinated push, more investment across several sectors at once than any single private investor would rationally undertake alone, a policy implication that shaped decades of development planning debate.
