This paper studies the different mechanisms and the dynamics through which demography is channelled to the economy. We analyze the role of demographic changes in the economic development process by studying the transitional and the long-run impact of both the rate of population growth and the...

Au-delà de la forte hétérogénéité des réalités socio-économiques nationales dans le monde arabe, il y a bien une logique institutionnelle commune qui est à l’origine des révoltes récentes, celle de coalitions dominantes se perpétuant au pouvoir pour contrôler les rentes issues de...

We develop a simple open-economy AK model with collateral constraints that accounts for growth-reversal episodes, during which countries face abrupt changes in their growth rate that lead to either growth miracles or growth disasters. Absent commitment to investment by the borrowing country,...

This paper extends the standard neoclassical model by considering a technology sector through which an economy with limited human capital attempts to catch up with a given “locomotive” pushing exogenously technical progress. In periods of technological stagnation, economies close enough to...

We present an intertemporal model of consumption and savings incorporating liquidity constraints and non-separable preferences. We solve the problem numerically and characterize the optimal consumption behavior. We explore the traditional puzzles highlighted in the empirical literature as excess...

Parfit's Repugnant Conclusion stipulates that under total utilitarianism, it might be optimal to choose increasing population size while consumption per capita goes to zero. We evaluate this claim within a canonical AK model with endogenous fertility and a reduced form relationship between...

This paper studies to which extent a firm using a scarce resource input and facing environmental regulation, can still manage to have a sustainable growth of output and profits. The firm has a vintage capital technology with two complementary factors, capital and a resource input subject to...

We study the optimal dynamics of an AK economy where population is uniformly distributed along the unit circle. Locations only differ in initial capital endowments. Despite constant returns to capital, we prove that transition dynamics will set in. In particular, we prove that the...

Innovative workplace practices based on multi-tasking and ICT that have been diffusing in most OECD countries since the 1990s have strong consequences on working conditions. Available data show together with the emergence of new organizational forms like multi-tasking, the increase in the...

This paper derives the optimal pace of capital accumulation at the firm level and the corresponding investment dynamics in the presence of an energy-saving technological progress. Energy and capital are complementary. When technical progress is disembodied, the firm invests once at the first...
