We show that the changes in expectations of future income driven by exogenous factors (such as the discovery of oil, an increase in global demand for natural resources, etc.) can cause movements in the real exchange rate (RER) in excess of, and sometimes even in the opposite direction to, what...

Despite ample empirical evidence on the prevalence of high discount rates among people, applied, quantitative-theoretical macro studies with exponential discounting often assume low positive, or even negative discount rate values. Relying on recent advances from the numerical optimal control...

There is voluminous literature on the reasons behind career interruptions, ranging from maternity leave and organizational layoffs, to national service and human capital acquisition. We show that a standard, neoclassical model of intertemporal consumption/saving and labor/leisure choices without...

This paper studies a continuous-time life-cycle model with a consumption-leisure choice made by a finitely-lived agent with a random lifetime. We explicitly account for the leisure constraint in the corresponding constrained optimal control problem with a commonly postulated solution structure,...

We compare the small sample performance (in terms of bias and root mean squared error) of L-moment estimator of 3-parameter Weibull distribution with Maximum likelihood Estimation (MLE), Moment Estimation (MoE), Least squared estimation (LSE), the Modified MLE (MMLE), Modified MoE (MMoE), and...

A static income tax evasion model à la Yitzhaki (1974) predicts that an increase in the tax rate causes taxpayers to increase their income declaration. In an important contribution, Lin and Yang (2001) obtained exactly the opposite result by extending the Yitzhaki (1974) model to a dynamic one...

We study the optimal size of a pay-as-you-go social security program for an economy composed of both permanent-income and hand-to-mouth consumers. While previous work on this topic is framed within a two-period partial equilibrium setup, we study this issue in a life-cycle general equilibrium...

Contrary to the usual presumption that welfare is maximized if consumers behave rationally, we show in a two-period overlapping generations model that there always exists a rule of thumb that can weakly improve upon the lifecycle/permanent-income rule in general equilibrium with irrational...

In this paper we develop a stochastic endogenous growth model augmented with income tax evasion. Our model avoids some existing discrepancies between empirical evidence and theoretical predictions of traditional tax evasion models. Further, we show that: i) productive government expenditures...
