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. ...

The paper explores the implications of different autonomous demands, with differing rates of growth, in a demand-led growth model where policy makers are concerned about the ratios of public sector debt to income and external debt to income. The actual growth rate is explained in terms of the growth rate of aggregate demand, with emphasis in the formation of expectations about growth in the lat...

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...

abstract in this paper we test two versions of convergence hypothesis namely deterministic or conditional convergence and stochastic or catching up hypothesis using carrion-i-silvestre et al. (2005) stationary test. the results show latin and south american countries (lsa) catching up process toward the usa failed in 1980s and somewhat in 1990s. but in 2000s most of them could lie in convergenc...

the authors examine the effects of government expenditure on economic growth in iran, using annual data for the period of 1973-2003. in this paper, they lookat the offects of human, physical capital, and government budget on gdp. in the model developed in this paper, accumulation of human capital is dependent on physical. human capital, and government budget as well. the result indicate that go...
