Semiparametric inference in correlated long memory signal plus noise models
(2010-04)
This paper proposes an extension of the log periodogram regression in perturbed long memory series that accounts for the added noise, also allowing for correlation between signal and noise, which represents a common situation ...
Merging to License: Internal vs. External Patentee
(2003-01)
In this paper, we endogenize the decision of a research laboratory that owns a patented process innovation on whether to remain independent as an external patentee or to merge with a manufacturing firm, becoming an internal ...
A Simple Model of Anticompetitive Vertical Integration
(2003-01)
The result of neutrality of vertical integration for competition postulated by the Chicago School can be supported by a benchmark model with (1) an upstream monopolist, (2) homogeneous goods downstream and (3) observable ...
Doubly fractional models for dynamic heteroskedastic cycles
(2011-02)
Strong persistence is a common phenomenon that has been documented not only in the levels but also in the volatility of many time series. The class of doubly fractional models is extended to include the possibility of long ...
Environmental Policy in Unionized Industries
(2001-10)
[EN] This paper focuses on the effects of environmental policy over the perfomance of firms and workers, when there is local pollution. We assume that the government chooses the environmental policy announcing an upper ...
Choice of Product Variety for the Durable Goods Monopolist
(1999-01)
This paper analyzes the strategic choice of variety by a monopolist seller of a durable good as a means to mitigate his commitment problem. The monopolist chooses his product variety with a goal of ensuring that a strong ...
Linear and Nonlinear Causality between Energy Consumption and Economic Growth: the Case of Mexico 1965-2014
(MDPI, 2018-03-29)
This paper analyzes the causal link between aggregated and disaggregated levels of energy consumption and economic growth in Mexico between 1965 and 2014, with the presence of structural breaks stemming from the series. ...
Product Differentiation with Consumer Arbitrage
(2003-03)
We analyze the consequences of consumers behavior concerning personal arbitrage in a spatial discrimination context where firms know the consumers distribution but cannot distinguish them by location. The firms' equilibrium ...
Numerical Distribution Functions for Seasonal Unit Root Tests
(2011-12)
When working with time series data observed at intervals smaller than a year, it is often necessary to test for the presence of seasonal unit roots. One of the most widely used methods for testing seasonal unit roots is ...
Is a Small Monte Carlo Analysis a Good Analysis? Checking the Size, Power and Consistency of a Simulation-Based Test
(Springer, 2002)
In this paper we study the relationship between the number of
replications and the accuracy of the estimated quantiles of a distribution
obtained by simulation. A method for testing hypotheses on the quantiles
of a ...
