although there is a tendency worldwide towards alternative methods in effectively managing weeds, use of herbicides to control weeds in conventional agriculture is still inevitable. with regard to externalities (through unsystematic use of herbicides) imposed upon environment, in the present paper it has been tried to study the willingness to pay of wheat farmers to plan for reducing the side e...

Childbearing pattern has a mutual culture-based relationship with marital satisfaction. The present study aimed to compare the childbearing pattern of women with marital satisfaction and those with marital dissatisfaction in Tehran, Iran. This comparative study was conducted on 196 females during 2015-2016. The participants were divided into two groups of marital satisfaction (Mar-S; n=98) and ...

I examine a model where agents differ in their discount factors. It has long been known that in the long-run, the most patient household or individual ends up owning all the capital, provided there is a maximum sustainable stock. I show that this is no longer true when there is sustained growth. I examine a model where there is endogenous growth due to learning-by-doing, the “Arrow-Romer” model...

A possible alternative to the Solow-Swan model is some variant of a model of endogenous growth either in the form of the AK model developed by Romer (1986), Lucas (1988) and Rebelo (1991) or in the subsequent group of models by Romer (1990), Grossman and Helpman (1991a, b), and Aghion and Howitt (1992) that focus more explicitly on the determinants of technological change. In this article we st...

Alan Auerbach has given us a valuable paper loaded with new empirical research on the macroeconomics of fiscal policy. I agree with his basic conclusion that there is “little evidence that (the effects of discretionary fiscal policy) have provided a significant contribution to economic stabilization, if, in fact, they have worked in the right direction at all.” I, therefore, concur with his sup...

In many cases the electric field is the gradient of a potential. In those cases a measured voltage is completely determined by the points connected to the measuring device. But if the curl of the electric field vector is non-vanishing (i.e. the magnetic field is time-dependent), a measured voltage may depend on the topology of the circuit. This effect was discussed in articles by Romer (1982), ...

Frankel and Romer [Frankel, J., Romer, D., 1999. Does trade cause growth? American Economic Review 89 (3), 379-399] documented positive effects of geographically determined trade openness on economic growth. At the same time, critics fear that openness can lead to a "race to the bottom" that increases pollution and reduces government resources for investments in health and education. We use Fra...
