This paper develops an endogenous growth model with dualism in human capital accumulation of two types of individuals. The government imposes a proportional redistributive tax on the resources of the rich individual to finance the educational subsidy given to the poor individuals. We find out the properties of optimal tax cum educational subsidy policy using Stackelberg differential game framew...

We study the implications of the creative destruction lifecycle of innovation for asset prices. We develop a general equilibrium model of endogenous firm creation and destruction where “incremental” innovations by incumbents and “radical” innovations by entrants drive the volatility of growth prospects of the economy. Higher entry—bigger threat of displacement of incumbents by entrants—implies ...

This paper combines horizontal and vertical innovations to build an endogenous growth model that allows for structural change. Older technologies are continuously replaced by newer ones due to creative destruction and new technologies appear as a result of horizontal innovations and as a result of consumers’ preferences for variety. We assume fixed operational costs for the manufacturing sector...

Research and development (R&D) is a key determinant of long run productivity and welfare. A central issue is whether a decentralized economy undertakes too little or too much R&D. We develop an endogenous growth model that incorporates parametrically four important distortions to R&D: the surplus appropriability problem, knowledge spillovers, creative destruction, and congestion externalities. ...

We consider a growth model proposed by Matsuyama [K. Matsuyama, Growing through cycles, Econometrica 67 (2) (1999) 335–347] in which two sources of economic growth are present: the mechanism of capital accumulation (Solow regime) and the process of technical change and innovations (Romer regime). We will shown that no stable cycle can exist, except for a fixed point and a cycle of period two. T...

We introduce publicly funded education into R&D-based economic growth theory. Our framework allows us to i) explicitly describe a realistic process of human capital accumulation within these types of growth models, ii) reconcile semi-endogenous growth theory with the empirical evidence on the relationship between economic development and population growth, and iii) revise the policy invariance ...

Using a two-bloc endogenous growth model calibrated to two generic sending and receiving countries of equal size, we assess the growth and welfare impact of world migration flows of different skill compositions. The sending country (East) has a lower total factor productivity and a lower endowment of skilled labour. Migration can induce two growth-enhancing effects: an efficiency effect from th...

In many models, economic growth is driven by people discovering new ideas. These models typically assume either a constant or growing population. However, in high income countries today, fertility already below its replacement rate: women are having fewer than two children on average. It distinct possibility that global population will decline rather stabilize the long run. standard this has pr...

The sniffles, sneezes, aches, and pains of flu are a dreaded part of the winter season. The fear of another deadly pandemic is ever imminent, and this issue’s Select looks at recent efforts to understand this ever-shifting virus. From efforts aiming to predict its geographical spread to those that elucidate the basic viral biology and host response, researchers are looking for new ways to stay ...
