{{Main|Economic growth}}

''Growth economics'' studies factors that explain [[economic growth]]&nbsp;– the increase in output ''[[per capita]]'' of a country over a long period of time. The same factors are used to explain differences in the ''level'' of output ''per capita'' ''between'' countries, in particular why some countries grow faster than others, and whether countries [[catch-up effect|converge]] at the same rates of growth.

Much-studied factors include the rate of [[Investment (macroeconomics)|investment]], [[population growth]], and technological change. These are represented in theoretical and [[empirical]] forms (as in the [[neoclassical growth model|neoclassical]] and [[endogenous growth model|endogenous]] growth models) and in [[growth accounting]].<ref>{{unbulleted list citebundle|{{harvp|Samuelson|Nordhaus|2010|loc=ch. 27, "The Process of Economic Growth"}}.|{{cite encyclopedia |author-link=Hirofumi Uzawa |last=Uzawa |first=H. |date=1987 |dictionary=The New Palgrave Dictionary of Economics |edition= |editor-first1=John |editor-last1=Eatwell |editor-first2=Murray |editor-last2=Milgate |editor-first3=Peter |editor-last3=Newman |pages=483–489 |chapter-url=http://www.dictionaryofeconomics.com/article?id=pde1987_X001477 |doi=10.1057/9780230226203.3097 |isbn=978-0-333-78676-5 |chapter=Models of growth |access-date=16 October 2017 |archive-date=17 October 2017 |archive-url=https://web.archive.org/web/20171017042317/http://www.dictionaryofeconomics.com/article?id=pde1987_X001477 |url-status=live }}}}</ref>
