This paper combines horizontal and vertical innovations to generate an endogenous growth model allowing for structural change as an endogenous phenomenon. Every industry is profitable only for a limited period of time, making the effective time of existence of the technology endogenous and...

In this paper we present an inter-temporal optimization problem of a representative R&D firm that simultaneously invests in horizontal and vertical innovations. We posit that learning-by-doing makes the process of quality improvements a positive function of the number of existing technologies...

Summary The paper extends the two-class Pasinetti model with workers and capitalists to allow for endogenous growth. Sustained per-capita growth results from positive externalities of investment which for its part only occur if workers devote time to education so that an efficient use of new...

We present a macroeconomic growth model in which investment in physical capital exhibits positive externalities which raise the stock of knowledge. Treating physical capital and knowledge as two separate variables, we show that the model can generate endogenous growth. It is demonstrated that...

This paper empirically studies non-linearities in debt sustainability analysis by resorting to the modern estimation technique of panel smooth transition regression (PSTR). We assess euro area debt sustainability by analysing the reaction of the primary balance to changes in public debt,...

With this paper our objective is to study the effects of different deficit policies in an endogenous growth model with publicly funded human capital accumulation and public debt, where we allow for heterogeneous households. Two types of households are considered. One household acquires human...

With this paper, our objective is to empirically study public debt sustainability by estimating a fiscal reaction function where the primary balance relative to GDP is assumed to be a function of the public debt to GDP ratio of the previous year and of other macroeconomic variables. In...

In this paper we empirically analyze the effect of the vaccinations against the SARS-CoV-2 virus on the Covid-19 pandemic for European countries from February 2021 to February 2022 with weekly data. We perform panel fixed effects estimations, GMM estimations and nonlinear penalized spline...

Empirical studies analyzing the effect of climate change on output growth sometimes neglect economic variables. This yields a biased picture of the growth process and does not represent a good approximation of the true data generating process. Thus, the question arises how valid the results are...
