In previous papers [Spear and Young (2014, 2015)], we surveyed the origins, evolution, and dissemination of optimal growth, two-sector and turnpike models up to the early 1970s. Regarding subsequent developments in growth theory, a number of prominent observers, such as Fischer (1988), Stern (1991), and McCallum (1996), maintained that after significant progress in the 1950s and 1960s, economic growth theory “received relatively little attention for almost two decades” [Fischer (1988, p. 329)], and that “by the late 1960s early 1970s, research on the theory of growth more or less stopped” [Stern (1991, p. 259)]. Stern went on to say “the latter half of the 1980s saw a rekindling of growth theory, particularly in the work of Romer . . . and Lucas” (1991, p. 259), that is to say, in the form of “endogenous growth” models. McCallum, for his part, wrote (1996, p. 41), “After a long period of quiescence, growth economics has in the last decade (1986–1995) become an extremely active area of research.” Moreover, Brock and Mirman's (1972b) paper was the sole “extension” of Ramsey–Cass–Koopmans to a “stochastic environment” mentioned by McCallum (1996, 49).

This paper deals with the development of growth models from the optimal one-sector neoclassical approach of Cass–Malinvaud–Koopmans vintage, through two-sector, multisector, and turnpike models, and proceeds to discuss their displacement by the single-sector stochastic growth model. We also focus on the definitional shift regarding the turnpike. This is done by surveying both unpublished and published work by Uzawa, Cass, Koopmans, and McKenzie regarding growth and the turnpike, the cross-fertilization between them, and how this brought about the conflation of optimality and the turnpike, and the metamorphosis of the notion of the turnpike, from that of Dorfman–Samuelson Solow, to the Koopmans–McKenzie “amalgam” of models. Finally, the appearance of endogenous growth models, based on the work of Shell and Uzawa, is dealt with.

The main divisions of the theoretical economic growth literature that we study today include exogenous and endogenous growth models that have transitioned through a number of notions and criticisms. Proponents of exogenous growth models argue that technological progress is the key determinant of long‑run economic growth as well as international productivity differences. Within the endogenous growth models, there are two notions that are propagated. The first postulates that capital used for innovative purposes can exhibit increasing returns to scale and thus account for the international productivity differences we observe today. The key determinants include knowledge, human capital, and research and development. The second argues that factors that affect the efficiency of capital, and hence cause capital flight, can also explain international productivity differences. These factors that affect the efficiency of capital include government spending, inflation, real exchange rates, and real interest rates. Our study results reveal that there is still no agreement on the dominant theoretical economic growth model amongst economists that can fully account for international productivity differences. We conclude that the future of theoretical economic growth is far from over and more work needs to be done to develop more practical structural economic growth models.

<p>This paper can be described as a significant exploratory study that will provide a significant contribution to knowledge to consider crucial issues which need to be barriers to understanding or a temptation/ requirement to judge some practices as ‘better’ than others for stock market development effective approach and implement successful stock market performance and economic growth. Recent analysis of the link between financial development and growth, gained from insights acquired as a result of using the technique of endogenous growth models, has illustrated that growth without exogenous technical progress and that growth rates could be related to technology, income distribution and institutional arrangements. This provides the theoretical background that empirical studies have lacked; illustrating that financial intermediation affects the level of economic growth. Resulting models have provided new impetus to empirical research of the effects of financial development. The birth of the new endogenous growth theory has facilitated the development of improved growth models where the long-term rate could be affected by a number of elements. These included technology, education and health policies in the process of economic development, capital accumulation, government policies and institutional activities in the role of financial development in economic growth.</p>

This article presents some findings of an analysis of innovation input - output relationship in EU member states. The first section of the paper considers the role of innovation in economic growth with particular attention to the new endogenous growth models. In the second part, the dichotomous approach to innovation and its measures is presented. The last section contains the methodology and outcome of research. The results of the study show that R&D expenditures, ICT and human capital are the key innovation inputs that affect such innovation outputs as innovation and patent propensity and new-to-market sales.

The 2018 Nobel Economics Prize was awarded to two American economists - William D. Nordhaus and Paul M. Romer - who designed methods for better assessing environmental issues and technological advances on growth. This year’s Laureates, Nordhaus was the first person to create an intergrated model to assess interactions between society and nature and Romer laid the foundation for what is now called endogenous growth theory. According to the Swedish Royal Academy of Sciences, these two macroeconomists’ research have helped “significantly broaden the scope of economic analysis by constructing models that explain how the market economy interacts with nature and knowledge” which integrates climate change measures into long-term sustainable economic growth.

The numerous versions of endogenous explanations of economic growth emphasize the importance of technological change driving forces, as well as the existence of appropriate institutional arrangements. Endogenous growth theory contributes to a better understanding of various experiences with long-term growth of countries and regions. It changes the key assumptions of the Neoclassical growth theory and participates in the modern regional development physiology explanation. Based on these conclusions, the paper: a) explicates the most important theoretical postulates of the theory, b) explains the most important factors of economic growth in the regions in light of the Endogenous growth theory messages and c) emphasizes the key determinants of regional competitiveness which in our view is conceptually between the phenomena of micro- and macro-competitiveness and represents their necessary and unique connection. First of all, micro-competitiveness is transformed into a regional competitiveness; then regional competitiveness is transformed into a macro-competitiveness. In turn, macro - influences the microeconomic competitiveness, and the circle is closed. After that, the process starts over again.
