A. This paper reports quantitative implications of a stochastic endogenous growth model in which growth displays a concave relationship with respect to competition. This model is consistent with unavoidable facts related to market structure, that other innovation-based endogenous growth models fail to replicate. This model shows promising empirical properties in both the shortand long-te...

In this paper, we explore the dynamic properties of an endogenous growth model with finite patent length. We show that there exists a unique equilibrium growth path and that this path exhibits damped oscillations in contrast to the equilibrium path of an endogenous growth model with infinite patent length.We also examine the effects of patent policy on social welfare and show that infinite pate...

This paper considers leisure externalities in a Lucas (1988) type model in which physical and human capital are necessary inputs in both sectors. In spite of a non-concave utility, the balanced growth path is always unique in our model which guarantees global stability for comparative-static exercises. We analyze and quantify the effects of preferences toward leisure on labor supply and welfare...

The impact of pollution and abatement policy within a stochastic endogenous growth model is analyzed. Environmental care is provided by the government and financed through income taxation and government bonds. Due to environmental preferences and partial perception of the individual’s impact on pollution, government debt influences equilibrium growth. Hence, there is an additional growth effect...

The Ramsey model is an analytical structure aimed at explaining intertemporal optimal growth. As a consequence, business cycles cannot be generated resorting to this structure, unless one introduces some source of inefficiency. Our central argument is that firms forecast future demand using a simple rule and thus they fail to perceive the full extent in which demand is capable of growing. Hence...

This paper studies the interrelation between anthropogenic global warming and economic growth. It is assumed that deviations from the pre-industrial average global surface temperature negatively affect aggregate output and utility. The government levies a tax on output and a tax on greenhouse gases. Assuming a basic endogenous growth model the effects of varying the tax rates are analyzed as co...

In this paper the impacts of income and consumption taxes are analyzed within a model of stochastic endogenous growth with congestion. It is shown that the optimal amount of governmental input diminishes with uncertainty and that the optimal financing depends on the relation between the degrees of rivalry and relative risk aversion. Due to the insurance effect associated with the taxation of st...

This paper clarifies the role of ICT capital in economic growth. Albeit ICT remarkably contributes to economic growth, there are few studies on ICT capital in ICT sector from theoretical point of view. In this paper, production function of ICT which is used as input of intermediate good in final good and ICT sectors is incorporated into our model. In this setting, we analyze the role of ICT on ...
