We study the economic mechanism which sustains the substitution of a marginal method for another when demand increases, in the presence of scarce resources. In those Ricardian dynamics, it is shown that the outgoing method is determined by the quantity side of the problem, the incoming method by...

We analyze the interplay between longevity, pollution and growth. We develop an OLG model where longevity, pollution and growth are endogenous. The authorities may provide two types of public services, public health and environmental maintenance, that participate to increase agents’ life...

This paper focuses on dynamic of diffusion of Information and Communications Technology (ICT) and their impact on labor productivity. Our contribution lies in taking into account the non-linearity of this relationship arguing successively integration time and a time when new productivity gains...

Biofuel policies (blend mandate or tax credit) have impacts on food and energy prices, and on land-use. The magnitude of these effects depends on the market response to price, and thus on the agricultural supply curve, which, in turn, depends on the land availability (quantity and agronomic...

We propose a new criterion which reflects both the concern for welfare (utility) and the concern for rights in the evaluation of economic development paths. The concern for rights is captured by a pre-ordering over combinations of thresholds (floors or ceilings on various quantitative...

The Great Recession seems to be a natural experiment for macroeconomics showing the inadequacy of the predominant theoretical framework - the New Neoclassical Synthesis - grounded on the DSGE model. In this paper, we present a critical discussion of the theoretical, empirical and...

We study the changing international transmission of US monetary policy shocks to 14 major OECD countries over the period 1981Q1-2010Q4. We use a time-varying parameter factor augmented VAR approach to study the effective federal funds rate shocks together with a large data set of 265, major...

Using Consensus Economics survey data on experts' expectations, we aim to model the 3- and 12-month ahead ex-ante risk premia on the Yen/USD and the British Pound/USD exchange markets. For each market and at a given horizon, we show that the risk premium is well determined by the conditional...

The aim of this paper is to propose a behavioral characterization of individuals who underestimate probability modifications and to characterize this behavior in the standard preferences representation models under risk (Expected utility, Dual theory, Rank Dependant Utility Theory and MaxMin...

Public policies can change the number of equilibria in an endogenous growth model. This work shows that in a growth model with monopolistic competition the existence of externalities not internalized by the agents can result in a multiplicity of equilibria. Government intervention in the economy...
