There is a wide literature on the dynamic adjustment of employment and its relationship with the business cycle. Our aim is to propose a statistical model that offers a congruent representation of post-war UK labour market. We use a cointegrated vector autoregressive Markov-switching model where...

This paper considers the relationship between congruence and encompassing. Congruence is defined formally, and though it is not testable directly, it can be tested indirectly via tests of misspecification. Empirically more than one model can appear congruent, but that which encompasses its...

This retrospective provides a biographical history of Denis Sargan's career and reviews his contributions to econometrics, emphasizing the breadth of his work in both theoretical and applied econometrics. We include a complete bibliography for Denis and a list of PhD theses that he supervised -...

Intertemporal models of the current account generally assume that global shocks do not affect the current account. We use this assumption to identify global and country-specific shocks in a bivariate VAR. We test the quality of the identification using evidence from G7-data. In accordance with...

We document and account for two facts regarding the relation between international interest rates and total factor productivity (TFP) in a sample of developing countries. First, there is a negative correlation between both variables at quarterly frequency. Second, the share of agricultural labor...

This paper provides a characterisation of the set of dynamic models in which symmetric duopolists have incentives to raise their common cost. The dynamic analysis has two advantages over existing static models. First, it avoids conceptual weaknesses, allowing conjectures to be derived...
