Die regionale Struktur und das Volumen der sächsischen Exporte und Importe erklären sich nicht nur durch die relativen Kostenunterschiede zwischen Sachsen und den Handelspartnern; mitentscheidend sind auch die Handelskosten für Exporte und Importe der sächsischen Wirtschaft. Unter...

Gravity Equations are broadly used to estimate the impacts of trade impediments on trade flows. It is often stated that results are implausibly high. In theoretical foundations of the gravity equation, trade costs usually enter as icebergmelting-costs. This paper offers an alternative approach...

A basic assumption of the gravity equation of international trade is that increasing trade costs lower exports. Butintuition and theory imply that a high export volume lowers bilateral trade costs as well, because a fixed cost intensivetrade sector probably bears lower average costs with more...

We consider the adiabatic equation of state for partially ionized non-ideal plasma. Plasma isentropes are calculated with the Padé technique in the chemical picture. The interplay of ionization/dissociation equilibrium and non-ideality is investigated.

This paper examines the optimal trade and hedging decisions of a competitive exporting firm which faces concurrently hedgeable exchange rate risk and non-hedgeable inflation risk. The macroeconomic interaction between exchange rate and domestic inflation rate risk is described by a state...

In the framework of the industrial economics approach to banking we extend the analysis of hedging against default on loans to the case of two types of credit risk. Standard results on the optimal hedge volume and the hedging effectivity from the single-risk case are shown to carry over to the...
