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.

The paper revisits the impact of uncertainty on the decision problem of a bank. The bank extends risky loans to private investors and sells deposits to savers at fixed rates. The uncertainty under which deposit/loan-portfolios are chosen by banks is endogenized through an information system that...

This paper examines the behavior of the regret-averse firm under exchange rate uncertainty. Regret-averse preferences are characterized by a modified utility function that includes disutility from having chosen ex-post suboptimal alternatives. We show that the conventional results that the firm...

Basel II changes risk management in banks strongly. Internal rating procedures would lead one to expect that banks are changing over to active risk control. But, if risk management is no longer a simple "game against nature", if all agents involved are active players then a shift from a...

Credit risk is one of the most important forms of risk faced by national and international banks as financial intermediaries. Managing this kind of risk through selecting and monitoring corporate and sovereign borrowers and through creating a diversified loan portfolio has always been one of the...

National and international investors are exposed to risk, stemming from volatile asset prices and inflation uncertainty. However investors can enter futures markets to hedge against these risks. The paper develops a dynamic hedging model, where the evolution of asset price, price level and...
