In this paper, we examine whether there is an “ideal” level of financial development, somewhere between financial capital overaccumulation and financial capital underaccumulation. We construct indexes of non-bank or speculative financial development, financial (bank) deepening, and...

This paper combines the standard incomplete markets model of uninsurable idiosyncratic risks and borrowing constraints with the Arrow/Romer approach to endogenous growth to analyze the interaction of risk, growth, and inequality, the latter also endogenously determined in equilibrium. We derive...

This paper presents an imperfect competition framework where growth is described as successful R&D investments in decreasing production-cost technologies. Innovation and imitation processes are modelled as activities requiring different amounts of investment, whose outcome is uncertaint both as...

We analyze the implications of innovation and social interactions on economic growth in a stylized endogenous growth model with heterogenous research firms. A large number of research firms decide whether to innovate or not, by taking into account what competitors (i.e., other firms) do. This is...

A model of economic growth is presented in which productivity is embodied in machines that are self-replicating. Productivity is subject to continuous random shocks, and machine owners compete for a limited supply of raw labor. Economic growth is driven by a Darwinian process whereby...

This paper discusses the influence of technological externalities on the dynamic properties of accumulation paths in a two-sector growth model in discrete time.

The paper airns to amend the standard monopolistic competition framework - and its endogenous growth extension - introducing both heterogeneity among producers and a form of 'Schumpeterian' competitive selection process. According to our view, the introduction of heterogeneity implies that the...

The paper addresses a topical issue – how expansionary fiscal policy affects the debt to GDP ratio. It examines whether the projected future economic growth (stimulated by government spending) is sustained with the resulting national debt. It is discussedif government investment in...

We set up a three-period overlapping generation model in which young individuals allocate their time to schooling and work, healthy middle aged individuals allocate their time to leisure and work and their income to consumption and savings for retirement, and old age individuals live off their...

Recent empirical research has shown that income per capita in the aftermath of natural disasters is not necessarily lower than before the event. In many cases, income is not significantly affected and surprisingly, can even respond positively to natural disasters. Here, we propose a simple...
