Corruption, Extortion, and the Boundaries of the Law

Abstract: We consider a setup in which a principal must decide whether or not to legalize a socially undesirable activity. The law is enforced by a monitor who may be bribed to conceal evidence of the offense and who may also engage in extortionary practices. The principal may legalize the activity even if it is a very harmful one. The principal may also declare the activity illegal knowing that the monitor will abuse the law to extract bribes out of innocent people. Our model offers a novel rationale for legalizing possession and consumption of drugs while continuing to prosecute drug dealers. (JEL D82, L22, K4) The Author 2008.

Multivariate Standardized Time Series for Steady-State Simulation Output Analysis

Abstract: The theory of standardized time series, initially proposed to estimate a single steady-state mean from the output of a simulation, is extended to the case where more than one steady-state mean is to be estimated simultaneously. Under mild assumptions on the stochastic process representing the output of the simulation, namely a functional central limit theorem, we obtain asymptotically valid confidence regions for a (multivariate) steady-state mean based on multivariate standardized time series. We provide examples of multivariate standardized time series, including the multivariate versions of the batch means method and Schruben's standardized sum process. Large-sample properties of confidence regions obtained from multivariate standardized time series are discussed. We show that, as in the univariate case, the asymptotic expected volume of confidence regions produced by standardized time series procedures is larger than that obtained from a consistent estimation procedure. We present and discuss experimental results that illustrate our theory.

Long-Lasting Economic Effects of Pandemics:Evidence on Growth and Unemployment

Abstract: This paper studies long economic series to assess the long-lasting effects of pandemics. We analyze if periods that cover pandemics have a change in trend and persistence in growth, and in level and persistence in unemployment. We find that there is an upward trend in the persistence level of growth across centuries. In particular, shocks originated by pandemics in recent times seem to have a permanent effect on growth. Moreover, our results show that the unemployment rate increases and becomes more persistent after a pandemic. In this regard, our findings support the design and implementation of timely counter-cyclical policies to soften the shock of the pandemic.

Families of periodic orbits in the planar Hill’s four-body problem

Abstract: In this work we perform numerical explorations of some families of planar periodic orbits in the Hill approximation of the restricted four-body problem. This approximation is obtained by performing a symplectic scaling which sends the two massive bodies to infinity, by the means of expanding the potential as a power series depending on the mass of the smallest primary, and taking the limit as this mass tends to zero. The limiting Hamiltonian depends only on the relative mass of the second smallest primary. The resulting dynamics shares similarities with both the restricted three-body problem and the restricted four-body problem. We focus on certain families of symmetric periodic orbits of the infinitesimal particle, for some values of the mass parameter. We explore the evolution of these families as the Jacobi constant, or, equivalently, the energy, is varied continuously, and provide details on the horizontal and vertical stability of each family.

What brand extensions need to fully benefit from their parental heritage

Abstract: It is well established that consumer acceptance of a brand extension depends on how strongly it fits with its parental origins. Less appreciated is how this acceptance also depends on the mental association created in consumers’ minds between the extension and its parent brand. Our investigation considers the gateway role played by this association’s mental accessibility in allowing extensions to fully benefit from their parental heritage. Six studies examine the effect of reinstating an extension’s association with its parent brand on extension evaluations. When reinstatement enhances the parental association’s accessibility, it strengthens the parent brand’s influence, leading to more or less favorable extension evaluations contingent upon the extension’s fit with its parental origins. These reinstatement effects carry important implications for brand-extension managers and researchers.
