In this paper, we describe a novel iterative procedure called SISTA to learn the underlying cost in optimal transport problems. SISTA is a hybrid between two classical methods, coordinate descent ("S"-inkhorn) and proximal gradient descent ("ISTA"). It alternates between a phase of exact...

We use a behavioural microsimulation model embedded in a numerical optimization procedure in order to identify optimal (social welfare maximizing) tax-transfer rules. We consider the class of tax-transfer rules consisting of a universal basic income and a tax defined by a 4th degree polynomial....

This paper begins the synthesis of two currently unrelated literatures: the human capital approach to health economics and the economics of cognitive and noncognitive skill formation. A lifecycle investment framework is the foundation for understanding the origins of human inequality and for...

We construct a model of offshoring with externalities and firm heterogeneity. Due to the presence of externalities, temporary shocks like the Y2K problem can have permanent effects, i.e., they can permanently raise the extent of offshoring in an industry. Also, the initial advantage of a country...

In this paper we discuss tests for residual cross section dependence in nonlinear panel data models. The tests are based on average pair-wise residual correlation coefficients. In nonlinear models, the definition of the residual is ambiguous and we consider two approaches: deviations of the...

In many countries, Employment Protection Legislation (EPL) establishes less strict dismissal procedures for specific groups of workers. This paper builds a simple matching model with heterogeneous workers in order to analyze this feature of EPL. We use the model to analyze the effects of reforms...

Consumption expenditure declines sharply at the time of retirement for many households, but the majority maintain a smooth consumption path. A simple life cycle model with uncertainty about the time of retirement can account for this pattern. A richer version of the model is calibrated to data...

Incomplete information is a commitment device for time consistency problems. In the context of time consistent labor income taxation privacy can lead to a Pareto superior outcome and increases the effectiveness of public education as a second best policy

Do individuals choose their reference groups, i.e. their Joneses, or are they culturally transmitted across generations? We provide evidence that feeds the theoretical debate about the endogeneity or exogeneity of reference groups. Our findings for Uruguay suggest that reference groups are...
