This paper shows that the two main models in the buffer stock saving literature can be nested in a model that varies the level of available social insurance. Equivalently, the assumption about the time series process for labor income (and social insurance during unemployment) is crucial in...

We provide easy to verify sufficient conditions for the consistency and asymptotic normality of a class of semiparametric optimization estimators where the criterion function does not obey standard smoothness conditions and simultaneously depends on some nonparametric estimators that can...

We consider the choices available to a defined contribution (DC) pension plan member at the time of retirement for conversion of his pension fund into a stream of retirement income. In particular, we compare the purchase at retirement age of a conventional life annuity (i.e., a bond-based...

Relying on a Constant Relative Risk Aversion utility function, we use panel data for Argentina to compute risk-adjusted income and poverty measures and to analyze their determinants. Taking risk into account increases poverty. The regression analysis suggests that many household characteristics...

Spatial inequality in developing countries is due to the natural advantages of some regions relative to others and to the presence of agglomeration forces, leading to clustering of activity. This paper reviews and develops some simple models that capture these first and second nature economic...

In this paper, using the framework of a Roy theoretical model, we examine the performance of return migrants in Albania. We ask two main questions: (i) Had they chosen not to migrate, what would be the performance of return migrants compared to the non-migrants? and (ii) What would be the...

We show that a life-cycle model with realistically calibrated uninsurable labor income risk and moderate risk aversion can simultaneously match stock market participation rates and asset allocation decisions conditional on participation. The key ingredients of the model are Epstein-Zin...

Meltzer (2001b) argues that the current trend for downgrading the role of money in standard macro models is erroneous as it masks those monetary transmission channels which operate through changes in relative yields of assets. This paper shows that the scope of these changes can be empirically...

In this paper we present a citizen-candidate model of representative democracy with endogenous lobbying. We find that lobbying induces policy compromise and always affects equilibrium policy outcomes. In particular, even though the policy preferences of lobbies are relatively extreme, lobbying...

Digital goods are bitstrings, sequences of 0s and 1s, which have economic value. They are distinguished from other goods by five characteristics: digital goods are nonrival, infinitely expansible, discrete, aspatial, and recombinant. The New Economy is one where the economics of digital goods...
