In this paper, we used the Autoregressive Distributed Lag (ARDL) model and the bounds test approach to estimate the elasticity of demand for natural gas in Western and Central Canada. The best model specification selected by Schwarz Information Criterion (SIC) for each province suggests that there exist long-run relationships between the dependent variable and independent variables for all provinces, except Ontario. Consumption per capita in these provinces can be explained by natural gas prices, electricity prices, income, and heating degree days (a measurement for the weather factor) in levels for the selected specification. The results show that natural gas demand is very inelastic with respect to natural gas prices and also with respect to heating degree days.

This paper explores the link between agriculture investment and agriculture output in Namibia. The existing theory on investment and growth constitutes a basis for empirical work on investment-output nexus. Neither the neoclassical nor the new growth theories on investment have considered the growth effects of investment at sector and industry level and its implication on capital allocation, particularly for developing countries that are resource constrained. The key question addressed in this paper is whether investment in agriculture is associated with agriculture output, both at the sector and sub-sector levels. The paper adopted the ARDL bounds test model constructed with quarterly data for the period 2000 to 2020 and found that investment and agricultural output exhibit a long-run relationship. The coefficient estimates showed that public investment, development bank loans and agriculture export have a positive impact on agricultural output while inflation, lending rates and commercial bank loans have a deleterious effect. The long-run causality tests suggest that there is unidirectional causality between commercial credit expenditure and aggregate agriculture output, as well as a unidirectional causality running from exports to livestock and crop sub-sector output. Based on error correction terms, agriculture output tends to rapidly adjust to short-term disturbances, hence rebound of agriculture output to a long-run growth path can take place with minimum or no delays. This study concludes that the Keynesian hypothesis is valid for Namibia's agriculture and the direction of causality is from investment to agriculture growth. Therefore, the role of government in supporting sustainable development of the agricultural sector cannot be overemphasised.

This essay examines the relationship between exchange rate volatility, estimated using a GARCH model, and level of trade for Sweden and Finland. The data used was collected from Refinitive Eikon Datastream with monthly observations for the time period January 2005 - December 2022. The obtained results indicate that the volatility of the Swedish Krona and Euro positively increases the level of trade for Sweden respectively Finland according to the ARDL model. However, while examining different time perspectives the conclusions resulted in inconclusiveness for the countries and perspectives. The ARDL bounds test for Sweden corresponded with inconclusive results regarding a possible positive long term relationship between SEKs exchange rate volatility and level of trade. Furthermore, the Granger causality test did not state a short term relationship between the two variables for Sweden nor did it state a reversed relationship. On the other hand, for Finland, the ARDL bounds test and Granger causality test denied both a long term and short term positive relationship between the EURs exchange rate volatility and level of trade for Finland. However, for Finland a reversed Granger causality test was shown indicating that the level of trade has an impact on the volatility of the EURs exchange rate.
