Traditionally, research has been devoted almost exclusively to estimation of underlying structural models without adequate attention to the drivers of diffusion and interaction across cross section and spatial units. We review some new methodologies in this emerging area and demonstrate their...

The transparency and openness of the monetary policymaking process at the Bank of England has provided very detailed information on both the decisions of individual members of the Monetary Policy Committee and the information on which they are based. In this paper we consider this decision...

Using data over a 34-year span on UK quoted firms, this paper seeks to identify the factors that increase the likelihood of exit of firms. Firms may disappear through the mutually precluding events of bankruptcies and acquisitions. We use a competing-risks hazard model to determine...

Firms exit through the mutually precluding events of bankruptcy and acquisition. We use a competing risks hazard regression model to identify the characteristics leading to each of these two outcomes using over thirty years of data on US and UK quoted firms. We find evidence about the way in...

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 describes a simple extension of popular tests of equality of hazard rates in a two-sample or k-sample setup to a situation where the covariate under study is continuous. In other words, we test the null hypothesis that the hazard does not depend on the value of the covariate against...

Dynamic stochastic general equilibrium models featuring imperfect competition and nominal rigidities have become central for the analysis of the monetary transmission mechanism and for understanding the conduct of monetary policy. However, it is agreed that the benchmark model fails to generate...
