Assigning proctors to exams with scatter search
Ramalhinho-Lourenço, Helena; Martí, Rafael; Laguna, Manuel - Department of Economics and Business, Universitat … - 2001
In this paper we present an algorithm to assign proctors to exams. This NP-hard problem is related to the generalized assignment problem with multiple objectives. The problem consists of assigning teaching assistants to proctor final exams at a university. We formulate this problem as a...

Iterated local search
Ramalhinho-Lourenço, Helena; Martin, Olivier C.; … - Department of Economics and Business, Universitat … - 2000
Iterated Local Search has many of the desirable features of a metaheuristic: it is simple, easy to implement, robust, and highly effective. The essential idea of Iterated Local Search lies in focusing the search not on the full space of solutions but on a smaller subspace defined by the...

Exploiting fitness distance correlation of set covering problems
Finger, Markus; Stützle, Thomas; Ramalhinho-Lourenço, … - Department of Economics and Business, Universitat … - 2001
The set covering problem is an NP-hard combinatorial optimization problem that arises in applications ranging from crew scheduling in airlines to driver scheduling in public mass transport. In this paper we analyze search space characteristics of a widely used set of benchmark instances through...

Heterogeneous consumers and fiscal policy shocks
Anderson, Emily; Inoue, Atsushi; Rossi, Barbara - Department of Economics and Business, Universitat … - 2011
This paper studies empirical facts regarding the effects of unexpected changes in aggregate macroeconomic fiscal policies on consumers that are allowed to differ depending on their individual characteristics. We use data from the Consumption Expenditure Survey (CEX) to estimate individual-level...

Effects of uncertain lifetime and annuity insurance on capital accumulation and growth
Fuster, Luisa - Department of Economics and Business, Universitat … - 1998
This paper studies the effects of uncertain lifetime on capital accumulation and growth and also the sensitivity of those effects to the existence of a perfect annuities market. The model is an overlapping generations model with uncertain lifetimes. The technology is convex and such that the...

Heterogeneous life-cycle profiles, income risk and consumption inequality
Primiceri, Giorgio E.; Rens, Thijs van - Department of Economics and Business, Universitat … - 2006
Was the increase in income inequality in the US due to permanent shocks or merely to an increase in the variance of transitory shocks? The implications for consumption and welfare depend crucially on the answer to this question. We use CEX repeated cross-section data on consumption and income to...

A simple model of multiple equilibria based on risk
Costain, James S. - Department of Economics and Business, Universitat … - 1998
This paper shows how risk may aggravate fluctuations in economies with imperfect insurance and multiple assets. A two period job matching model is studied, in which risk averse agents act both as workers and as entrepreneurs. They choose between two types of investment: one type is riskless,...

The risk of divorce and household saving behavior
Luna, Libertad González; Özcan, Berkay - Department of Economics and Business, Universitat … - 2008
We analyze the impact of an increase in the risk of divorce on the saving behaviour of married couples. From a theoretical perspective, the expected sign of the effect is ambiguous. We take advantage of the legalization of divorce in Ireland in 1996 as an exogenous increase in the likelihood of...
