The analysis contained in the YHEC report indicates that the report did not consider adequately the role of competition in the market for health insurance. This is a major weakness and appears in part to be due to a late deletion of competition from the report’s final research brief by the...

Many theoretical models of transition are driven by the assumption that economic decision making is subject to political constraints. In this paper we empirically test whether the winners and losers of economic reform determined voting behaviour in the first five national elections in the Czech...

In this paper, the problem of mergers and acquisitions under pro¯t uncer- tainty is considered. A two ¯rm model is developed where M&A activity is modelled as an act of risk diversi¯cation. We study the case where only the larger ¯rm engages in M&A activity and the case where both ¯rms do....

Thresholds defined on the level and change in the HHI (Herfindahl- Hirschmann Index) applied to market shares seem to be the main instrument to select notified mergers for investigation in both the EU and US. We question the use of such a selection rule in di?erentiated products industries. We...

This is a revised and extended version of the authors’ 2003 Trinity Economic Paper. It describes Hamilton’s (2001) approach to nonlinear econometric modelling and some of the methods of nonlinear optimization, as before, but adds significantly to the investigation of Hamilton’s Gauss...

This paper presents a general framework for analysing stochastic stability in models with evolution at two levels. Under certain conditions the theory of nearly-complete decomposability can be used to disentangle these two levels. They can then be studied separately and the equilibrium of one...

This paper provides an empirical analysis of own- and cross-price elasticities of substitution for the 1989-2000 Italian automobile industry. We use product-level data consistent with a structural model of equilibrium in a differentiated products oligopolistic industry and follow a random...

In this paper, the problem of mergers and acquisitions under pro¯t uncer- tainty is considered. A two ¯rm model is developed where M&A activity is modelled as an act of risk diversi¯cation. We study the case where only the larger ¯rm engages in M&A activity and the case where both ¯rms do....

We construct consumer price indices for Canada, mainly based on the expenditure records of Canada’s federal penitentiaries. Regional price variation was much greater in Canada in the late nineteenth century than in the northern U.S. The new data suggest substantial price decline to 1900....

The paper highlights the increased dispersion in net external positions in recent years, particularly among industrial countries. It provides a simple accounting framework that disentangles the factors driving the accumulation of external assets and liabilities (such as trade imbalances,...
