Since the financial crisis in 2008, slow growth has riddled Europe and the Covid-19 pandemic is amplifying the challenge. Promoting economic growth and transforming to a more knowledge-based industrial structure will be high on the agenda for the coming decades. We study how more and better...

This paper studies a two-country production economy with complete and frictionless financial markets and international trade in which competition in R&D leads to endogenous new firm creation and economic growth. Current monopolists ("incumbents") and potential new firms ("entrants") compete in...

This paper presents an endogenous growth model of migration and technological diffusion with transitional dynamics, which provide explanations for the empirical pattern of the mobility transition. A two-skill group extension of this model offers new hypotheses regarding the skill composition of...

We prove a generalized, multi-factor version of the Uzawa steady-state growth theorem. In the two-factor case, the theorem implies that a neoclassical growth model cannot be simultaneously consistent with empirical evidence on both capital-augmenting technical change and the elasticity of...

The paper develops the Basic Climate Economic (BCE) model featuring the core elements of climate economics and climate policy. The BCE model incorporates fossil stock depletion, pollution stock accumulation, endogenous growth, and climate-induced capital depreciation. We first use graphical...

We develop a model to rationalize and examine so-called "research bubbles", i.e. research activities based on overoptimistic beliefs about the impact of this research on the economy. Research bubbles occur when researchers selfselect into research activities and the government aggregates the...

We analyze the implications for monetary policy when deficient aggregate demand can cause a permanent loss in potential output, a phenomenon we term output hysteresis. In the model, the incomplete stabilization of a temporary shortfall in demand reduces the return to innovation, thus reducing...

This paper introduces heterogeneity of cross-technologies interactions into the double-differentiated R&D-based endogenous growth model. In this model new technologies appear continuously and older are outdated generating structural change. All technologies may interact with each other through...

In this paper we analyze the importance of recycling in the strive for sustainable development. In contrast to former approaches we emphasize the role of the waste stock as a source of valuable inputs. We enhance a Romer (1990) type endogenous growth model by a material balance condition that...

We study a series of sustained growth models in which households' preferences are affected by the consumption of other households as summarized by average consumption. In endogenous growth models, the equilibrium paths involve lower savings and lower growth than the corresponding efficient...
