This study extends the dynamic conditional correlation model to allow day-specific correlations of shocks across international stock markets. The properties of the resulting periodic dynamic conditional correlation (PDCC) model are examined, with the model then applied to study the intra-week interactions between six developed European stock markets and the US over the period 1993 2005. We find...

A policy debate continues about the relative merits and and negative consequences of federal policies that encourage patent protection to university research results. Given the importance of university research for innovation in many industries, the effects of such policies are of critical importance to firms. This paper examines the impact of the increase in university patenting on the effecti...

We show how classical spacetime emerges from quantum gravity through the study of a quantum FRW cosmological model coupled to a free massive scalar field using a new asymptotic expansion method of the Wheeler-DeWitt equation. It is shown that the coherent states of the nonadiabatic basis of a particular generalized invariant give rise to the quantum back reaction of matter field proportional to...

In this article, nonlinear propagation of envelope gravity waves is studied in baroclinic atmosphere. The classical (2 + 1) dimensional nonlinear Schrödinger (NLS) equation can be derived by using the multiple-scale, perturbation method. Further, via the semi-inverse method, the Euler–Lagrange equation and Agrawal’s method, the time–space fractional (2 + 1) dimensional nonlinear Schrödinger (FN...

Any non-spherical distribution of density inside planets and stars gives rise to a non-spherical external gravity and change of shape. If part or all of the observed zonal flows at the cloud deck of Jupiter and Saturn represent deep interior dynamics, then the density perturbations associated with the deep zonal flows could generate gravitational signals detectable by the Juno mission and the C...

The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...

In an open multi-country economy, the safe assets supply shapes pattern of international capital flows. A higher productivity growth rate raises net inflows for economies with abundant assets, but reduces scarce assets. The cross-section analysis on a sample 170 over 1980–2013 confirms theory. evidence is robust instrument-variable (IV) method. JEL Classifications: F15, F36, F43

the main aim in this research has been to determining the growth regime in iran based on an open economy concerning the bhaduri and marglin(1990) model.  this model which has been widely used in post keynesian economics is a kaleckian-post keynesian macroeconomic model which is based on effective demand. bhaduri and marglin(1990) concerning wage as a cost item as well as a component of aggregat...

ABSTRACT Little is known about the factors that influence whistleblowing for contingent workers. This study compares intentions of 146 traditional full-time and We find workers are significantly less likely to whistleblow than Some these differences in appear be due feelings powerlessness, organizational citizenship behavior, commitment have relation their organizations. offer future research i...

This paper seeks to investigate the determinants of banking network profitability in Iran from 2007 to 2012. The results of our study indicate that both bank-specific factors and macroeconomic factors influence banks’ profitability in Iran. Results confirm that bank profitability is significantly influenced by investment to total assets ratio, non-performing loans to total assets ratio, a...
