This paper examines the impact of real exchange rate volatility on economic growth in Kenyan. The study employed the Generalized Autoregressive Condition of Heteroscedasticity (GARCH) and computation of the unconditional standard deviation of the changes to measure volatility and Generalized...

Recent geography and trade empirical studies based on monopolistic competition [Hanson, 1998 ; Head and Ries, 1999 ; Hummels, 1999], suggest high levels of trade price elasticities (between 3 and11). However, direct estimations of price-elasticities in trade equations, using price indexes at...

We propose a structural econometric evaluation for auctions with discrete increments. Although very common in practice, this kind of mechanism raises many theoretical difficulties. First, there are no closed form equilibriumstrategies. Thus the econometrician cannot rely on a single formula to...

By limiting the scope for substitution between commodities, other things equal quantity constraints raise the cost of living. Thus, rationed families have higher povery lines than unconstrained ones. This heterogeneity in both resources and poverty lines means that, in principle, bivariate...

In the last decades a liberalization of the electric market has started; prices are now determined on the basis of contracts on regular markets and their behaviour is mainly driven by usual supply and demand forces. A large body of literature has been developed in order to analyze and forecast...

Recently, Vogelsang (1999) proposed a method to detect outliers which explicitly imposes the null hypothesis of a unit root. It works in an iterative fashion to select multiple outliers in a given series. We show, via simulations, that under the null hypothesis of no outliers, it has the right...

We propose residual based tests for cointegration using local GLS detrending (Elliott, Rothemberg and Stock (1996), ERS) to eliminate separately the deterministic components in the series. We consider two cases, one where only a constant is included and one where a constant and a time trend are...

Explained variance (R^2) is a familiar summary of the fit of a linear regression and has been generalized in various ways to multilevel (hierarchical) models. The multilevel models we consider in this paper are characterized by hierarchical data structures in which individuals are grouped into...

Various noninformative prior distributions have been suggested for scale parameters in hierarchical models. We construct a new folded-noncentral- t family of conditionally conjugate priors for hierarchical standard deviation parameters, and then consider noninformative and weakly informative...

A bi-directional relationship between FDI and economic reforms in ten Central European countries is tested, along with the role of the EU in breaking a potential vicious circle of insecurity, little investment, slow reforms, low prospects of EU membership and hence high insecurity. Using panel...
