This paper extends the cross sectionally augmented panel unit root test proposed by Pesaran (2007) to the case of a multifactor structure. The basic idea is to exploit information regarding the unobserved factors that are shared by other time series in addition to the variable under...

The conventional menu cost framework performs poorly with realistic labour supply elasticities; the menu costs required for price rigidity are very high and the welfare consequences of monetary disturbances are negligible. We show that the presence of dual labour markets greatly improves the...

This paper uses a very simple example (two goods, linear symmetric demand and cost) to study the effects of the price cap regulatory mechanism. We show that if a given price vector is preferred (using current welfare as the criterion) to another, then it is not necessarily the case that it is...

The optimal allocation of a public health care budget across treatments must take account of the way in which care is rationed within treatments since this will affect their marginal value. We investigate the optimal allocation rules for health care systems where user charges are fixed and care...

The purpose of this paper is the theoretical and empirical comparison of alternative GARCH-in-mean models. We examine three GARCH specifications: Bollerslev's (1986) GARCH model, Taylor (1986) - Schwert's (1989) GARCH model, and Nelson's (1991) Exponential GARCH model. In addition, we employ...

This paper investigates inequality in smoking-related mortality risk, focusing on the intergenerational transmission of smoking. We estimate a latent factor model for smoking initiation, cessation and mortality risk using the British Health and Lifestyle Survey (HALS). The empirical analysis...

This chapter provides a concise guide to the econometric methods that are available to evaluate the impact of health policies.

Every year 35% of the 10 million hospital admissions in Italy occurs outside the patients' Local Health Authority of residence. In this paper we look for explanation for this phenomenon and estimate gravity equations for "trade" in hospital care using a Poisson pseudo maximum likelihood method....

The paper empirically assesses microeconomic exporting-productivity nexus using the data for Ukrainian manufacturing and service sectors for the years 2000-2005. The results of the estimation show that firms with higher total factor productivity (TFP) levels in the period prior to entry are much...
