This paper contributes in economic literature by investigating the impact of defense spending on income inequality in case of Iran using time series data over the period of 1971-2011. For this purpose, we have applied the ARDL bounds testing approach to cointegration for long run relationship in...

This paper examines the impact of natural gas consumption, real gross fixed capital formation and trade on the real GDP in case of Tunisia over the period of 1980-2010. We used Auto-Regressive Distributed Lag (ARDL) bounds testing approach to test the existence of long run relationship between...

This paper empirically parallels two approaches: The first one follows the studies of Halicioglu (2009), Jalil and Mahmud (2009), and Jayanthakumaran et al. (2012) which attempt to introduce energy consumption and trade into the environmental function (related carbon dioxide ‘CO2’ emissions...

This paper models a dynamic scholar’s allocation of time between academia and professional activities outside academia, given the academic labor market and social interactions. The model shows how particularly in less developed countries business and political networks may have large negative...

This paper deals with the empirical investigation of causal relationship between financial deepening, economic growth and poverty reduction using quarter frequency data in case of Pakistan over the period of 1972-2011. We applied the ARDL bounds testing approach by incorporating structural...

When focusing on firm’s risk-aversion in industry equilibrium, the number of firms may be either larger or smaller when comparing market equilibrium with and without price uncertainty. In this paper, we introduce risk-averse firms under cost uncertainty in a model of spatial differentiation...

This paper examines the question: ‘What is Middle East and North Africa (MENA) region initially needed: grow output or mitigate CO2 emissions? This question is a focus on the issue of both production function and environmental function based on the environmental Kuznets curve (EKC) approach....

This paper modifies a standard model of law enforcement to allow for learning by doing. We incorporate the process of enforcement learning by assuming that the agency’s current marginal cost is a decreasing function of its past experience of detecting and convicting. The agency accumulates...

Using the principal-agent- supervisor paradigm, this paper examines the occurrence of collusion in a setting where the principal has no information about the supervisor and the agent does not necesarily know the supervisor’s preferences.We formally prove the occurrence of collusion is more...

The paper implements the autoregressive distributed lag (ARDL) bounds testing, supplemented by the Johansen-Juselius (JJ) approaches to cointegration to explore a long run relation among energy use, economic growth, financial development, capital, and trade openness in Australia. We also apply...
