We propose a new microeconomic explanation for the divergent experiences of economies in forming human capital. We suggest that the positive effect of a longer life expectancy on human capital formation arises from two separate effects: a life-expectancy effect and a prolonged intergenerational...

When productivity is fostered by an individual's own human capital as well as by the economy-wide average level of human capital, individuals under-invest in human capital. The provision of subsidies for the formation of human capital, conditional on the subsidy being self-financed by tax...

The Fisher scoring method is widely used for likelihood maximization, but its application can be difficult in situations where the expected information matrix is not available in closed form or when parameters have constraints. In this paper, we describe an interpolation family that generalizes...

We analyze in this paper the growth and welfare consequences arising from the lack of auditing commitment in a credit market with costly state verification. Specifically, two endogenous growth models, of which one allows lenders to commit to costly auditing strategies to identify borrowers'...

We study the endogenous relationship between health care, life expectancy and output in a neoclassical growth model. Although health care directly diverts resources away from goods production, it prolongs life expectancy, which in turn leads to higher savings and, hence, capital formation...

We study an overlapping generations model where the probability that money can lose its value is an endogenous function of the level of aggregate real money balances. The economy can display multiple stationary equilibria where the aggregate bubble on money is stochastic and the level of...
