Se cuantifica el grado de precisión al predecir la inflación del índice de precios al consumidor (IPC) mediante agrupaciones homogéneas de los rubros en la canasta del IPC. Dos conjuntos de agrupaciones homogéneas alternativos al conjunto de agrupaciones convencionales se obtienen al...

An artificial neural network (hence after, ANN) is an information processing paradigm that is inspired by the way biological nervous systems, such as the brain, process information. In previous two decades, ANN applications in economics and finance; for such tasks as pattern reorganization, and...

We build a 4-equation model of the inflation process in South Africa (which has recently adopted inflation targeting), including the exchange rate, consumer prices, producer price, and import prices. This provides useful information on the speed and extent of exchange rate pass- through, and...

Estimates of the NAIRU are usually derived either from a Phillips curve or from a wage curve. This paper investigates the correspondence between the operational NAIRU-concepts and the steady state of a dynamic wage-price model. We derive the parameter restrictions that secure that...

Empirical studies looking for changes over time in exchange rate pass-through to consumer prices generally consider the context of a changing inflation mean to examine this issue. This paper allows for endogeneity in exchange rate movements and proposes a new method to test this hypothesis for...

The authors address empirically the implications of structural breaks in the variance-covariance matrix of inflation and import prices for changes in pass-through. They define pass-through within a correlated vector autoregression (VAR) framework as the response of domestic inflation to an...

The study models the behaviour of the Central Bank of Nigeria. An extended Taylor's framework that accounted for exchange rate dynamics and political risk factors was adopted. In order to capture both ex-ante and ex-post behaviours of the monetary authority in the country, Markov-Switching...

The article analyses the impact of exchange rate changes on German export and import prices. The analytical framework is a mark-up model which is based on the assumption that the markets under consideration are imperfectly competitive as well as segmented. Hence, firms will no longer set prices...

In this paper we investigate the formation of Norwegian import prices of manufactures over the period 1970(1)-1998(3), thereby extending the sample period used in the study by Naug and Nymoen (1996). If international goods markets are perfectly integrated and the law of one price holds, then for...

We argue that Islamic principles, in particular the avoidance of ribā and gharar should be applied with respect to real economic value rather than to monetary value in terms of conventional currency. In order to reconcile monetary value with economic value, we propose a reference currency...
