This paper presents a dynamic general equilibrium model with default and collateral requirements. In contrast with previous literature, our model allows for liquidity contractions and general prepayment specifications. We show that liquidity substantially affects credit and prepayment risks, and...

We estimate the crowding out of private transfers caused by 70 y Más, a public assistance program for the rural elderly in Mexico for whom private support is an important source of income. Using data from the Mexican Income and Expenditure Survey and a triple differences approach, we find that...

In this paper we introduce communication into intergroup ultimatum bargaining in a lab. The responder groups vote whether to accept the proposals with unanimity required either for acceptance or for rejection. In contrast with the no-communication results reported in our previous study...

I characterize the set of implementable allocation functions in the standard one dimensional mechanism design environment where the relationship between private information and payoffs is possibly non-monotone. The characterization is useful in two aspects. First it leads to a rather mild...

Classical de?nitions of complementarity are based on cross price elasticities, and so they do not apply when goods are free. This context includes many relevant cases such as online newspapers and public facilities. We look for a complementarity notion for free goods that is: behavioural (based...

We provide a framework to evaluate whether or not a seller can increase his revenue in interacting with a privately informed buyer by using money-back guarantees (MBGs). The buyer's value for the good exhibits fi risk and his type is multidimensional giving the probability of Öt as well as the...

Classical deÖnitions of complementarity are based on cross price elasticities, and so they do not apply, for example, when goods are free. This context includes many relevant cases such as online newspapers and public attractions. We look for a complementarity notion that does not rely on price...

In this paper we present an endogenous growth model with physical and human capital accumulation and study the effects of labor and capital income taxation on the transitional dynamics to the balanced path. Our results amount to an extension of those in Caball\'{e} and Santos (1993) and offer...

This paper uses a recent demogrant for the elderly in Mexico City to estimate the e¤ect of an exogenous increase in the income of older individuals on the amount of private transfers they receive. My results show that not controlling for the endogeneity of income replicates the positive or...

We construct an intertemporal equilibrium with two agents with heterogeneous beliefs. Heterogeneity of beliefs induces volatility of the interest rate. We study the effect of financial innovation on interest rate volatility and conclude that, in a setting of asymmetric beliefs, introducing the...
