The paper revisits regression-based inequality decomposition, derives further theoretical results on the factor shares and applies them in an empirical setting. Noting that the approach based on Shorrocks and Fields is not directly applicable to an important welfare-based inequality index,...

This paper presents a methodological extension of Deaton's (1990) model for estimating price elasticities, by pooling Tunisian data from several surveys to improve the inter-cluster variability of unit values which is one of the key elements used in the derivation of these elasticities. Since...

In this paper, we develop a test for the existence of a middle 'band of inaction' in a three-regime threshold vector error correction model (TVECM). A Wald statistic is proposed for this purpose, its limiting distribution is derived (which is non-standard) and critical values calculated through...

This paper proposes a generalization of the nonlinear simultaneous equation model of Pesaran and Pick (2007) by modelling the comovement between the two endogenous variables as a smooth function of the magnitude of the endogenous variable rather than a step function. The threshold and the speed...
