Longevity has been increasing in the developed countries for almost two centuries and further increases are expected in the future. In the neoclassical growth models the case of population growth driven by fertility is well-known, whereas the properties of population growth caused by...

This paper studies equilibrium effect of fiscal policy disturbances within a dynamic general equilibrium model where tax evasion and underground activities are explicitly incorporated. There are three main results. (i) The underground sector mitigates the distortionary impact of fiscal policies,...

This paper shows under indeterminacy and tax evasion, an increase in corporate, labor or income tax rates pushes the economy into an expansionary pattern. These effects are reversed when the steady state is saddle-path stable.

We develop a new directed-search model of fertility and marriage, and apply it to two empirical problems: the rise in unmarried women’s share of births since 1970, and the fact that black women have lower marriage rates and higher rates of unmarried births than white women. The premise is that...

By reducing the risk of unwanted parenthood, more effective contraception reduces the cost of sex outside of marriage, increasing the value of single life. Could this explain why marriage and birth rates declined in the U.S. after 1970?. We illustrate our hypothesis with a one-period example. We...

It is shown that although government debt in principle has an ambiguous effect on the steady state capital stock in an OLG model of the Blanchard-Cass-Yaari variety, once stability of the steady state equilibrium is imposed there is an unambiguous negative relation between the level of...

This paper introduces underground activities and tax evasion into a one sector dynamic general equilibrium model with external effects. The model presents a novel mechanism driving the self-fulfilling prophecies, which is triggered by the reallocation of resources to the underground sector to...

Rejuveniles are "people who cultivate tastes and mind-sets tradi- tionally associated with those younger than themselves." (Noxon, 2006) In this paper, we study a standard AK growth model of overlapping generations populated by rejuve- niles. For our purposes, rejuveniles are old agents who...

This paper shows that the consumption-based asset pricing model (C-CAPM) with low-probability disaster risk rationalizes large pricing errors, i.e. Euler equation errors. This result is remarkable, since Lettau and Ludvigson (2009) show that leading asset pricing models cannot explain sizeable...

When the consumption growth rate is measured based upon fourth quarter data, it tracks predictable variation in future excess stock returns. Low fourth quarter consumption growth rates predict high future excess stock returns such that expected returns are high at business cycle troughs and low...
