The present study was aimed to investigate the effects of oil price shocks on discretionary fiscal policies in selected OPEC countries during 1980-2015. In this regard, the heterogeneous dynamic reaction to structural shock was examined using Panel Structural Vector Autoregressive (PSVAR) technique. Based on the findings, the effect of oil price shocks on discretionary fiscal policy was positiv...

The Internet is now a central enabler for sharing sustainability information. Yet, such enablement complicated through an exponentially increasing array of What lacking in the digital economy are objective and transparent mechanisms to provide reliable assessments published information timely efficient manner. In addressing limitation, this research proposes automated mechanism measuring transp...

Alternative market structures are distinguishable by the degree of parallel action exhibited by producers. We show that the correlation between output levels varies systematically with the degree of interdependence among firms, and establish an ordering among alternative behavioral hypotheses (Cournot, Stackelberg, Edgeworth/Bertrand, collusion, and perfect competition). Because the ordering is...

in this paper, the random walk hypothesis and the opec oil market efficiency have been examined. the random walk hypothesis states that prices are completely stochastic in nature so that they have 'no memory'. in its weak-form, changes in prices occur stochastically and, as a result, the random walk behavior of prices is usually used to test the weak-form efficiency. in order to study the rando...
