Background & Aims of the Study: Due to one-way flow of water in rivers Guilan, pollution trade theory and the system of Ratio-Trade (TRS) and Streeter - Phelps equation has been used. This system, with a view of the river self- purification and how the distribution and transport of pollutants, determined Ratio-Trade system (TRS) between the units and using this method offers optimal pat...

How do firms finance large cash flow requirements? We examine this in the context of firms that are subject to substantial cash flow requirements. We find that trade credit, inventory and cash stock reductions are all important in the short term for mild requirements. Larger and longer cash flow shortages give rise to more equity than debt finance. After the shocks, firms gradually adjust their...

We present a theory of why some countries negotiate trade agreements during economic downturns. We argue that political leaders can gain from such agreements because of the signals they send to their publics. Publics are less likely to blame leaders for bad economic conditions when they have implemented sound economic policies, such as signing and implementing agreements designed to liberalize ...

Water markets are developing as part of a Council of Australian Governments initiative to promote an efficient use of Australia's water resources. The consequences of these policies on river health is yet to be fully understood, but recognised as having significant interrelationships which need to be explored. This paper examines the consequences of introducing trade and allocating water for en...

International trade models typically assume that producers in one country trade directly with final consumers in another. In reality, of course, trade can involve long chains of potentially independent actors who move goods through wholesale and retail distribution networks. These networks likely affect the magnitude and nature of trade frictions and hence both the pattern of trade and its welf...

The report investigates fundamental trade-offs related to the static regulation performance in networked control systems with delay and saturation in the feedback loop. The trade-offs are a consequence of required L2-stability of the networked system, in the limit where the delay tends to infinity. First a relation between the relative static regulation accuracy and the static gain of the part ...
