Inflation erodes purchasing power of money and discourages consumption (and investment). Hence, output is higher the lower inflation.

Depression results in lower wages and lower prices of firm, while boom results in higher wage and price pressures

In the short run, changes in E are mirrored in changes in = EP/P*: P and P* are sticky In the long run, is independent of E: P adjusts If P is fully flexible, the long run comes about immediately and the nominal exchange rate does not affect the real economy Put differently, the choice of an exchange rate regime has mostly short run effects because prices and wages are sticky

Monetary union is the controversial end of a long process. History helps understand. Since paper money was invented, Europe’s monetary history carries important lessons. Particularly the bad ones. Before paper money, Europe was a de facto monetary union. Understand how it worked helps understand how the new union (EMU) works.

If we start with a high money stock (e.g. point M 0 ), domestic prices are high, balance of payments turns in deficit and gold flows out, but commodities in (current account surplus) Why? We have to buy other goods by gold. Converse holds for low money stock in initial situation.

Capital flows allow in short-term deviation from long-term equilbrium. if the stock of money increases, the domestic interest rate declines if the interest rate is below the international rate i*, it pays to borrow gold at home and ship it abroad, i.e. capital flows out

41 Prof. Dr. Herbert Brücker Lehrstuhl für Volkswirtschaftslehre, insbesondere Integration Europäischer Arbeitsmärkte Universität Bamberg | herbert.bruecker@uni-bamberg.de | www.uni-bamberg.de/sowi/bruecker Theory and Politics of European Integration A Monetary History of Europe Monetary equilibrium under gold standard Summing up: Money in excess of M translates into balance of payment deficits and gold outflows If money is in short supply (left of E = M), balance of payments is in surplus and gold flows in Point A may correspond to a point with imbalances in current and capital account, e.g. a point where the current account deficit exactly matches the capital account surplus This forms however only a short-term equilibrium since interest rates differ. Thus, the gold standard results in a balance of payments equilibrium in the short-run, and a current account and capital account equilibrium in the long-run where domestic interest rates and prices equal the international ones.

47 Prof. Dr. Herbert Brücker Lehrstuhl für Volkswirtschaftslehre, insbesondere Integration Europäischer Arbeitsmärkte Universität Bamberg | herbert.bruecker@uni-bamberg.de | www.uni-bamberg.de/sowi/bruecker Theory and Politics of European Integration A Monetary History of Europe The interwar period: three case studies  The British case: return to gold standard pre-war parity and refusal to devalue an overvalued currency relative to US breeds economic decline. Abolished unsustainable gold standard in 1931 and devalued currency by 30%. Cost: decade of miserable growth.  The French case: high debts hoping for German’s reparations, inflation soared after reparations failed. Return to gold standard and devaluation in 1928; undervaluation and beggar-your-neighbour policies protected economy first, but then others retaliate and the currency becomes overvalued, badly hit by Great Depression. The German case: hyperinflation, gold standard no option (reparations), devaluation and anti-inflation policy in 1924, turns into overvaluation in the early 1930s, and, finally, evading the choice of an appropriate exchange rate by resorting to ever-widening non-market controls under Nazi government.
