Harsanyi used expected utility theory to provide two axiomatizations of weighted utilitarian rules. Sen (and later, Weymark) has argued that Harsanyi has not, in fact, axiomatized utilitarianism because he has misapplied expected utility theory. Specifically, Sen and Weymark have argued that von...

We study empirically how close consumption-smoothing models employing present-value relationships fit data for Latin-American countries, either in an open-economy or closed-economy environment. Bivariate VARS are estimated using either individual-system or a joint-system techniques (OLS or GLS -...

The aim of the paper is to fulfill the gap for testing hypotheses on parameters of the log-normal stochastic volatility … that of the proposed test statistics for testing the null hypothesis of no persistence in the volatility. We then compare …

I examine the statistical model of permanent and transitory shocks to output under the following structural assumptions: An aggregate supply shock that raises output will cause the price level to fall and an aggregate demand shock that initially raises output will cause the price level to rise....

This paper introduces a new bivariate autoregressive conditional framework (ACD×ACL) for modelling the arrival process of buy and sell orders in a limit order book. The model contains two dynamic components to describe the observed clustering of durations and order types: a duration process to...

VAR models are used in practice in preference to VARMA models due to the difficult issues involved in the identification and estimation of VARMA models. This paper examines if VAR models are good enough for forecasting macroeconomic variables. To answer this question, we extend the Tiao and Tsay...

This paper empirically estimates a murder supply equation for the United States from 1965 to 2001 within a cointegration and error correction framework. Our findings suggest that any support for the deterrence hypothesis is sensitive to the inclusion of variables for the effect of guns and other...

This paper analyzes the robustness of the estimate of a positive productivity shock on hours to the presence of a possible unit root in hours. Estimations in levels or in first differences provide opposite conclusions. We rely on an agnostic procedure in which the researcher does not have to...

Structural vector autoregressions (SVARs) have become a standard tool used to determine the roles of monetary policy shocks in generating cyclical fluctuations in the United States. Using both long- and short-run identifying restrictions, various authors have explored the empirical response of...
