Secular Trends in U.S Saving and Consumption
Kaiji Chen, Ayse Imrohoroglu, Selahattin Imrohoroglu
National saving rate in the U.S. has been declining since the 1960s while the share of consumption in output has been increasing. We explore if a standard growth model can explain the secular trends...

Elimination of Social Security in a Dynastic Framework
LUISA FUSTER, AYSE IMROHOROGLU, SELAHATTIN IMROHOROGLU
Much of the existing literature on social security has taken the extreme assumption that individuals have little or no altruism; this paper takes an opposite assumption that there is full two-sided...
Social Security in an Overlapping Generations Economy with Land

Entry Costs, Intermediation, and Capital Flows
Ayse Imrohoroglu, Krishna B. Kumar
In this paper, we reexamine the question "Why doesn't capital flow from rich to poor countries?" posed, most recently, by Lucas (1990). We build a simple contracting framework where costly...
