This paper studies how the assignment of patents as collateral determines the savings of firms and magnifies the effect of innovative rents on investment in research and development (R&D). We analyse the behaviour of innovative firms that face random and lumpy investment opportunities in R&D....

In neoclassical theory, knowledge generates increasing returns - and therefore growth - because it is a public good that can be costlessly reused once created. In fact, however, much knowledge in the economy is actually tacit and not easily transmitted -and thus not an obvious source of...

We estimate the relative roles of factor inputs and productivity in explaining the level of economic development, which is measured as output per worker. For a large sample of countries, we show that alternative identifying productivity assumptions and alternative measures of human capital have...

Much of the recent interest in the relationship between growth and distribution has focused on advanced economies and neglected issues of development and structural transformation. The purpose of this paper is to make a contribution to this gap by arguing that, even in the short-run, some of the...

Combining concrete policy-oriented modeling strategies of World War II with what was received as traditional neoclassical theory, in 1956 Robert Solow constructed a simple, clean, and smooth-functioning "design" model that served many different purposes. As a working object it enabled...

Four stylised facts of economic growth in DCs are set up initially. Despite its obvious simplicity the linear growth model with subsistence consumption is able to reproduce two of them: a rise in the saving rate along with per capita income as well as ß-divergence. The speed of convergence...

In recent years, a large body of empirical research has investigated whether the predictions of secondgeneration growth models are consistent with actual data. This strand of literature has focused on the longrun properties of these models by using productivity and innovation data but has not...

Solow has repeatedly called for the development of models that combine equilibrium and out-of equilibrium outcomes or what he called a macroeconomics of the medium-run. This paper recounts the history of Solow's different attempts to address this issue. It starts in early 1950s when Solow...

From its flow tide, fueled by the Cold War, to its ebbing with the anti-growth movement and the economic crises of the early 1970s, the "growthmen" of MIT stood at the center of the dominant field in macroeconomics. The history of MIT growth economics is traced from Solow's seminal neoclassical...

Modern growth theory derives mostly from Robert Solow's "A Contribution to the Theory of Economic Growth" (1956). Solow's own interpretation locates the origins of his "Contribution" in his view that the growth model of Roy Harrod implied a tendency toward progressive collapse of the economy. He...
