DCM (Discrete Choice Models) is a package for estimating a class of discrete choice models. Written in Ox, DCM is a class that implements a wide range of discrete choice models including standard binary response models, with notable extensions including conditional mixed logit, mixed probit,...

The paper presents various tests for assessing whether a time series is subject to drift. We first consider departures from the null hypothesis of no drift against the alternative of a deterministic and/or a non-stationary stochastic drift with initial value zero. We show that the standard...

Despite the recent trend towards greater transparency of monetary policy, in many respects central bankers still prefer to speak with mystique. This paper shows that the resulting perception of ambiguity could be desirable. Under the plausible assumption that there is imperfect common knowledge...

The European Emissions Trading Scheme (ETS) limits CO2 emissions from covered sectors, especially electricity until December 2007, after which a new set of Allowances will be issued. The paper demonstrates that the impact of controlling the quantity rather than the price of carbon is to reduce...

This paper considers a multivariate t version of the Gaussian dynamic conditional correlation (DCC) model proposed by Engle (2002), and suggests the use of devolatized returns computed as returns standardized by realized volatilities rather than by GARCH type volatility estimates. The t-DCC...

Modern infrastructure, particularly electricity, is critical to economic development. South Asia, with inefficient and bankrupt state-owned vertically integrated electricity supply industries, encouraged private generation investment to address shortages selling power to largely unreformed state...

The purpose of this paper is to present a rank based approach to cross-sectional linear factor modelling. The emphasis is on approximating factor exposures in a consistent manner in order to facilitate the merging of subjective information (from professional investors) with objective information...

We consider a multi-award generalisation of King Solomon’s problem: k identical and indivisible awards should be distributed among agents, k < n, with the top k valuation agents receiving the awards. Agents have complete information about each other’s valuations. Glazer and Ma (1989) analysed the single-prize (i.e. k = 1) version of this problem. We show that in the ‘more than two agents’ problem the mechanism of Glazer and Ma admits inefficient equilibria and thus fails to solve Solomon’s problem. So, first we modify their mechanism to rule out inefficient equilibria and implement efficient prize allocation in sub-game perfect equilibrium when there are at least three agents. Then it is shown that a simple repeated application of our modified mechanism will distribute k (>1) prizes efficiently in sub-game perfect equilibria without any monetary transfers in equilibrium. Finally, in the multi-awards case we relax the...</n,>

We study incumbency advantage in a dynamic game with incomplete information between an incumbent and a voter. The incumbent knows the true state of the world, e.g., the severity of an economic recession or the level of criminal activities, and can choose the quality of his policy. This quality...

This paper examines how allowing individuals to emigrate to pay lower taxes changes the optimal non-linear income tax scheme in a Mirrleesian economy. Type-dependent participation constraints are borrowed from contract theory. An individual emigrates if his domestic utility is less than his...
