Several omnibus tests of the proportional hazards assumption have been proposed in the literature. In the two-sample case, tests have also been developed against non-parametrically specified ordered alternatives. This paper considers a natural extension of such monotone ordering to the case of...

Notions of monotone ordering with respect to continuous covariates in duration data regression models have recently been discussed, and tests for the proportional hazards model against such alternatives have been developed (Bhattacharjee and Das, 2002). Such monotone/ ordered departures are...

This paper focuses on testing long run macroeconomic relations for interest rates, equity, prices and exchange rates within a model of the global economy. It considers a number of plausible long run relationships suggested by arbitrage in financial and goods markets, and uses the global vector...

We re-connect money to in.ation using Goodfriend and McCallum's (2007) model where banks supply loans to cash-in-advance constrained consumers on the basis of the value of collateral provided and the monitoring skills of banks. We show that when shocks to monitoring and collateral dominate those...

Optimal nominal interest rates rule are usually set assuming that the underlying world is linear. Our work relaxes this assumption and examines the performance of optimal rules when non-linearities are present. In particular if the inflation-output trade off exhibits non linearities...

This paper investigates the drivers of industry and aggregate fluctuations. We model the dynamics of a panel of highly disaggregated manufacturing sectors. This allows us to consider directly the linkages between sectors typical of any production system, in a framework where the sectors are...

This paper uses an asymmetric multivariate model to investigate asymmetries in employment and pricing behaviour by firms. This generalises the approach of Granger and Lee (1989) and also exploits the cross-equation restrictions on the equations for prices and employment implied by a restricted...

Co-movements and correlations in the major macroeconomic aggregates has been the focus of much recent literature in business cycle research. In this paper we provide another dimension to business cycle analysis. We examine the evolution of the cross sectional distribution of the growth rates of...

There is growing evidence that the cross section of the growth rate of firms is subject to systematic distortions at business cycle frequencies. In this paper we briefly review this evidence and then offer a theoretical model that incorporates nonlinearities in the way in which firms respond to...

There is now a plethora of non-linear time-series models of output over the business cycle, and considerable empirical evidence that there are key non-linear, poorly understood mechanisms at work. Inventories, though a small part of the total flow of national income, play a disproportionately...
