The purpose of this paper is to revisit the Granger causal relationship between banking sector development and economic growth for forty developing countries in the period 1970-2012. In order to capture the different aspects of banking sector development, we develop two banking sector development indices and apply the panel bootstrapped approach to Granger causality testing approach properly taking into account cross-sectional dependence and heterogeneity issues. The empirical results show limited support for the supply-leading, demand-following and complementarity hypotheses. Our results also provide evidence as the causal relationship between banking sector development and economic growth exists in twenty five countries.
This paper examines the causal relationship between financial development and economic growth for 27 medium-income countries in the period 1970 to 2012. We develop a new proxy for financial development that refers to the input of real resources into the financial system and apply the panel bootstrapped approach to Granger causality. The results show, for three countries the findings support strong evidence on supply-leading hypothesis which implies that financial development induces economic growth and for six countries the findings support strong evidence on demand-following. Our results confirm for twenty one countries suggesting that their financial development does not depend on economic growth.
This paper tracks the financial growth in Tunisia over the period 1984–2016 with a special focus on the shadow economy. Using Tanzi's measures, we worked on a nonlinear autoregressive distributed lag (NARDL) model to test the impact of the informal economy. The results suggest that the long‐run effect of the financial growth becomes negative if there is a positive change in the shadow economy and the opposite holds. While changes in the shadow economy have no significant influence on the links between financial development and economic growth in the short run, they play a significant role in the Tunisian economy in the long run.
The article is an extension to the pricing models proposed by Jean Tirol that model the consumption of an environmental good. However, the different consumption patterns of this good, which is characterized by a taste parameter (two tastes or a continuum of taste); always verifying an imbalance between the profit of the monopoly (mainly natural); and the utility function of the consumer agent. Taxation on the price, in relation to consumer preferences, can ensure the objectives of an efficient management of a good which has variations in its physical nature. Moreover, a coefficient of variation in its nature, based on a scale of measurement, can achieve the convergence between economic and social objectives. The underlying results show that the consumer surplus is proportional to the variation between the average and marginal utility. In addition, maximizing monopoly profit provides a reasonable price that ensures social equity measures between the different users.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
