The response of hours to technology shocks is a key controversy in macroeconomics. We show that differences between RBC and NK models hinge on highly restrictive views of technology. We introduce CES production technologies and demonstrate that the response of hours depends on the...

We argue that the New-Keynesian Phillips Curve literature has failed to deliver a convincing measure of real marginal costs. We start from a careful modeling of optimal price setting allowing for non-unitary factor substitution, non-neutral technical change and time-varying factor utilization...

Capital-labor substitution and TFP estimates are essential features of many economic models. Such models typically embody a balanced growth path. This often leads researchers to estimate models imposing stringent prior choices on technical change. We demonstrate that estimation of the...

We study relative preferences in a general equilibrium model where households make social comparisons and/or get habituated to levels of labour-effort they supply and goods they consume. Bayesian estimations for the US support the existence of a society based on such preferences. In particular,...

The purpose of this paper is to contribute a new model of the Gold Standard, focusing on the interaction between resource scarcity and demographics. In a dynamic micro-founded model we find that: i) prices and equilibrium gold holdings increase with population (a scale effect), but decrease with...

Following the Arab-Spring protests, we examine macroeconomic interactions between a productive firm and a rent-seeking government characterized by a continuous probability of regime shift. The model is able to rationalize the early growth leaps witnessed in many Arab economies (the “Social...

Most growth models imply positive impacts on economic growth from greater openness. And a key factor linking openness and growth is the efficiency with which resources are used. Empirically, however, the efficiency impacts of trade have been ambiguous. Using a stochastic frontier analysis, we...

Many studies suggest that research productivity falls after tenure is granted. We have however limited choice-theoretic understanding of why this should occur. With some simplifying assumptions, we rationalize this as follows. Scholars are assumed to be “specialistsâ€: their research...

Despite the modern origins of endogenous growth theory, we argue that the ‘Idea for a Universal History with a Cosmopolitan Aim’ written by Immanuel Kant in 1784 provides an early and coherent example of such a theory. Kant’s endogenous growth mechanism is driven by the...

Using a New-Keynesian flexi-price model with external habit formation in consumption and labor supply, we identify the channels underlying the Easterlin Paradox (or “Happiness Inertia”, its generalization). These include whether external habit formation is in “difference” or “ratio”...
