In models with a capital spillover, the market outcome is not Pareto e cient since agents ignore the positive externalities caused by investment. One might conclude that taxes on investment or subsidies to consumption will reduce welfare. However in a model of endogenous growth, either a small tax on capital income, whose proceeds are wasted, increases growth and welfare or a small marginal sub...

This paper constructs a human-capital accumulation propelled endogenous growth model in which a home production sector is modeled explicitly. We con…rm …rst the basic equilibrium properties of a unique balanced-growth path, then conduct comparative statics and comparative dynamics exercises analytically. The implications of home production are explored in both the long and short runs, hence som...

Climate change and natural disasters, the COVID-19 pandemic, geopolitical shocks have increasingly disrupted school education around world in recent years. Whether leading to closures, destructions or repeated interruptions students’ learning experiences, these external translated into lost opportunities for students. In this context, systems face heightened pressure become ever more resilient,...

This paper constructs a two-sector unified growth model. Learning-by-doing in agriculture eventually allows the preindustrial economy to leave its Malthusian trap. But entrepreneurs in the manufacturing sector do not attempt invention if not much is known about natural phenomena. This delays the industrial revolution. Since entrepreneurs identify new useful knowledge at all times in a serendipi...

We consider a two-period overlapping generations model in which individual voters differ not only according to age but also productivity. In such a setting, a (redistributive) Pay-As-You-Go system is politically sustainable, even when the interest rate is larger than the rate of population growth. The medium wages workers (not the lowest) join the retirees to form a majority and vote for a posi...

In this paper we present an endogenous growth model with productive government spending and pollution. As to pollution we suppose that it is a by-product of aggregate production and that it negatively affects utility of the household but not production possibilities directly. Analyzing our model it is first shown that for reasonable parameter values there exists a unique balanced growth path wh...

This paper examines the importance of factor mobility within countries for the manifestation of agglomeration and location effects emphasized in the new economic geography literature. Working with a model of trade under monopolistic competition, the relationship of factor mobility (in particular labor) to industry adjustment and relocation is developed analytically, and then illustrated with a ...

This paper studies growth and welfare effects of fiscal policy in an endogenous growth model with productive public capital where we consider both distortionary and non-distortionary taxation in the model simultaneously. Analyzing the model it is assumed that the economy originally is on the balanced growth path when the government changes its fiscal parameters. The paper then studies growth an...

We develop a multi-sector general equilibrium model in which productivity growth is driven by the production of sector-specific knowledge. In the model, we find that long run differences in total factor productivity growth across sectors are independent of the parameters of the knowledge production function except for one, which we term the fertility of knowledge. Differences in R&D intensity a...

The paper examines the gains from North-South trade and their distribution. In a `new growth, new trade' framework, we examine the factors that determine four phases or stages of development in the South as equilibria: specialisation in a traditional good; the South in addition copies Northern innovative manufactured goods; the South begins to innovate in its own right and nally a stage in whic...
