This paper presents a novel test of cointegration that is robust to general forms of weak dependence in the innovation sequences and is simple to implement. In contrast to existing procedures, this is achieved without applying corrections to the test statistic for removing the effect of serial...

This study examined the impact of monetary policy on economic growth in Nigeria. The secondary data used include the Money supply, economic growth, Credit to the private sector, Interest rate and Exchange rate. The Vector Error Correction model (VECM) was adopted as the estimation technique of...

This article highlights the importance of statistical tests on the trend coefficient in cointegrating regressions when the stochastic regressors contain a deterministic linear trend. In addition to deriving asymptotic theory for t statistics constructed using integrated and modified ordinary...

Participants in the maritime industry place much interest in the Forward Freight Agreements (FFA/FFAs), being an indispensable tool for hedging shipping freight risk. Our paper innovates by directly comparing the FFA predictions with their actual future settlement prices as well as by examining...

This paper develops an international oligopoly model where foreign and domestic firms simultaneously choose their pricing strategies under the assumption of non-zero conjectural variations. The model captures the links between domestic and foreign producers’ prices and establishes a...

The present paper tests for the validity of long-run purchasing power parity (PPP) for the three key currencies of the recent floating exchange rate period, the US dollar, the German mark and the Japanese yen. The novelty of the paper is that the validity of the PPP conditions relating the...

This paper aims to study the recent increase in the spread of refined-crude petroleum prices in the US. We analyze the evolution of crude oil prices, refining costs, distribution costs, and taxes, comparing the pre and post covid periods. Fractional integration and cointegration methodologies...

The purpose of this paper is to investigate how well contemporary exchange rate theories explain fluctuations in exchange rates of emerging economies, before and after the Global Financial Crisis (GFC). As an example, the EUR/PLN exchange rate in 1999-2015 was selected as the currency pair that...

Corruption and inflation are two economic problems with serious social consequences. This paper analyzes the link between these two problems, focusing on the case of 19 prices observed for agricultural products in 90 countries since 2000. Using 'panel data cointegration' techniques, we conclude...
