This paper develops an overlapping-generations (OLG) model to analyze the consequences of demographic structure changes induced by an exogenous shift in the birth rate.We first show that a finite growth rate of the population that maximizes long-run capital per capita exists. Then, we examine...

This paper proposes the use of optimal grouping methods for determining the various age groups within a population. The cutoff ages for these groups, such as the age from wich an individual is considered to be an older person, are then endogenous variables that depend on the entire population...

This paper investigates the relation between liquidity and asset prices. It shows that, when banks balance sheets are marked to market and banks are targeting a financial leverage level - a situation similar to current environment - formation of Leverage Bubble phenomenon and suggests a new...

We build a continous-time general equilibrium model of a two-country, pure-exchange economy featuring taxes on the repatriation of dividends. We find approximate closed-form expressions for asset prices, returns joint dynamics and equity portfolios, thus giving a full description of equilibrium...

Impact of monetary policy on asset prices : lessons from a MIU model applied to the Fed Abstract -A tractable consumption-based and money-based asset pricing model is built to relate in closed form the risk premium, the risk free rate and the volatility of asset price to parameters of monetary...

Social and environmental ratings provided by social rating agencies are multidimensional. Using the six sub-ratings provided by the Vigeo rating agency, we perform a principal component analysis and we highlight three main socially responsible (SR) dimensions related to (1) the direct...

The aim of the paper is to analyze the impact of heterogeneous beliefs in an otherwise standard competitive complete markets discrete time economy. The construction of a consensus belief, as well as a consensus consumer are shown to be valid modulo a predictable aggregation bias, which takes the...

This paper studies the effects of multiple investment horizons and investors' bounded rationality on the price dynamics. We consider a pure exchange economy with one risky asset, populated with agents maximizing CRRA-type expected utility of wealth over discrete investment periods. An investor's...
