introduction: any rise in health expenditure is the main concern of householders and policymakers. a few studies have been conducted on assessing the determinants of expenditures and environmental quality from a macroeconomic point of view. this paper aimed to investigate the relationship between health expenditure and environmental quality in more than 114 developing countries between 1995 and...

The paper reports on the results of estimating both the longand short-run demand for money function in New Zealand, 1990–2000 using quarterly data and cointegrationand error-correction-based models. It is found that price, real income and interest rate variables are integrated of order 1 or I(1). Using Phillips and Hansen [Rev. Econ. Stud. 57 (1990) 99] fully modified estimation methods, we est...

It is no longer news that Nigeria runs a single-product economy where the only source of revenue for country crude oil exportation. Changes in prices international market continue to have severe implications on country's economy's growth rate, exchange rate and even inflation. This study seeks investigate impact four key variables (crude price, real inflation population) Nigeria’s economic grow...

This paper examines the relationship between foreign direct investment, openness and economic growth in Sudan during the period 1972-2011 using Granger causality and Johansen co-integration techniques to analyze the relationship and direction of causality between the variables. The study used autoregressive distributed lag (ARDL) approach to cointegration analysis proposed by Pesaran and Shin (...

In this paper, the effects of oil and gold prices on stock market index are investigated. We use a cointegrated vector autoregressive Markov-switching model to examine the nonlinear properties of these three variables during the period of January 2003 - December 2014. The Markov-switching vector-equilibrium-correction model with three regimes representing "deep recession", "mild recession" and ...

This study estimates the aggregate import demand function for Nigeria for the period of 1980 2010. Cointegration approach was implemented. While the error correction term in the estimated VEC model was evaluated for long run causal relationship, the short term coefficients were gauged for short term causal relationship between the explained and the explanatory variables. Results indicate: (i) t...

This paper investigates empirically the factors that influence real agricultural wage rates in Ghana, based on 1957 to 1991 data. The Johansen cointegration framework is used to examine long-run relationships among agricultural and urban wage rates, the domestic terms of trade between agriculture and nonagriculture, urban unemployment, capital stock in agriculture and the size of the rural popu...
