(Read sample chapter) Where to start with the textbook?

17. Feb 03 2004 Chapter 1 of Baldwin and Wyplosz illustrates 3 basic things What has happened in Europe over the past 50 years?

18. Feb 03 2004 1.European integration has always been driven by political factors, ranging from a desire to prevent Franco-German war to a desire to share the fruit of integration with the newly democratic nations in Central and Eastern Europe. –Yet while the goals were always political, the means were always economic What has happened in Europe over the past 50 years?

19. Feb 03 2004 2.There have been basically three big increases in European economic integration. –Formation of the customs union from 1958 to 1968 eliminated tariffs and quotas on intra-EU trade. –The Single Market programme implemented between 1986 and 1992 (although elements are still being implemented today) eliminated many non-tariff barriers and liberalised capital flows within the EU. –Finally, the European Economic and Monetary union melded together the currencies of most EU members. What has happened in Europe over the past 50 years?

20. Feb 03 2004 3.Each of these steps towards deeper integration – but especially the customs unions and the Single market programme – engendered discriminatory effects that triggered reactions in the non-member nations. –The discriminatory effects of EU integration has created a powerful gravitational force that has progressively drawn all but the most reluctant Europeans into the EU. –If there is a lesson to draw from this for the future, it is that the 2004 enlargement is likely to greatly magnify the pro-EU membership forces in the nations further east and south. What has happened in Europe over the past 50 years?

21. Feb 03 2004 Chapter 2 of Baldwin and Wyplosz looks at four very different topics Facts, Law, Institutions and the Budget

22. Feb 03 2004 A dominant feature of the EU members is their diversity in size and income levels. –In the EU15, there are only 5 large nations (40 million or more). The rest, with the exception of the Netherlands, are small or tiny, with national populations smaller than that of large cities like Paris or London. –The 2004 enlargement will greatly increase this dispersion since out of the 10 newcomers, only Poland is large (almost 40 million citizens). Facts

23. Feb 03 2004 –The economies of member states are also extremely disparate in size. –Just 4 of the EU15 economies account for two-thirds of the EU15’s GDP, i.e. the economies of the other 11 members add up to only one-third of the EU15’s GDP. –Again this dispersion will greatly widen with the 2004 enlargement. Taking all the 10 newcomers economies together will add only 5% to the EU15’s current GDP. Facts

24. Feb 03 2004 The EU is unique in that it has a supranational system of law. That is, on matters pertaining to the European Community, EU law and the EU Court take precedent over member states’ laws and Courts. Law

25. Feb 03 2004 While there are many EU institutions, only 5 really matter for most things. These are –the European Council –the Council of Ministers – the Commission – the Parliament –the Court. These 5 institutions work in concert to govern the EU and to pursue deeper and wider European economic integration. Institutions and legislative procedures

26. Feb 03 2004 The EU budget is rather small, representing only 1% of the EU15’s GDP. It is spent mainly on –the Common Agricultural Policy (half the budget), and on Cohesion, –resources destined for poor regions in the EU (a third of the budget). Budget

27. Feb 03 2004 The budget is funded through four main mechanisms but in the final analysis, each EU member pays roughly 1% of its GDP. The distribution of net contributions (receipts minus contributions) by member state is quite unequal. –In the EU15, the biggest net recipients are Luxembourg (the richest member) and the three poorest members (Greece, Portugal and Spain) Budget: recipents

28. Feb 03 2004 Read chapter 3 of Baldwin and Wyplosz to refresh your thinking about decision making in the Eurozone. Decision making

29. Feb 03 2004 Policy making in various areas is categorised into areas where the EU has ‘exclusive competency’, i.e. where the decision is made only at the EU level, areas where competency is shared areas where the EU has no competency, i.e. where decisions are made only at the national or sub-national level Decision making

30. Feb 03 2004 The allocation of policy areas to these three categories is determined by the Treaties and decisions of the EU Court of Justice. To clarify the allocation, the EU operates on the principle of subsidiarity, which says that unless there is a good reason for allocating a task to the EU level, all tasks should be allocated to national or sub-national governments. Decision making

31. Feb 03 2004 Four trade-offs: Diversity and information costs favour decentralised decision making. Scale economies favour centralisation. Democracy-as-a-control-device favours decentralisation. Jurisdictional competition favours decentralisation. To centralize or maybe not to centralize?

32. Feb 03 2004 Read chapter 10 of Baldwin and Wyplosz Also worth reading is Gros and Thygesen (1998) A monetary history of Europe

33. Feb 03 2004 Monetary union is the controversial end of a long process. History helps understand. Since paper money was invented, Europe’s monetary history has been agitated. Each bad episode carries important lessons. Before paper money, Europe was a de facto monetary union. Understand how it worked helps understand how the new union works. Why study history?

34. Feb 03 2004 Under metallic money (overlooking the difference between gold and silver) the whole world was really a monetary union Previous explicit unions only agreed on the metal content of coins to simplify everyday trading Metallic Money

35. Feb 03 2004 Bad money drives out good If two monies circulate alongside each other (eg gold and silver), and one of the currencies becomes overvalued, it is hoarded, and the other, depreciated currency is the only one that circulates. Gold discoveries in the 1850s What is Gresham’s law?

36. Feb 03 2004 The workings of the gold standard are described by David Hume’s price-specie mechanism Depends on (i) long-run neutrality of money and (ii) the effect of money on interest rates Money and the balance of payments are linked by trade flows Hume’s mechanism implies an automatic change in the money stock to achieve balance of payments equilibrium Figure 10.1 How did the Gold Standard work?

37. Feb 03 2004 Money determines the price level in the long-run. The price level affects the trade balance –If domestic prices are relatively high (low), we have a deficit (surplus) Trade balance is achieved when the stock of money is M 1 Hume’s mechanism: Return to balance is automatic –If we start with deficit (point A, high money stock M ), money flows out until we get back to balance Much the same story applies to the financial account –If the domestic interest rate is high (low), capital flows in (out) and the return to balance is automatic The balance of payments adds the current and financial accounts Hume’s price-specie mechanism

38. Feb 03 2004 Full convertibility at fixed prices of banknotes issued by central banks –So paper money is merely a convenient surrogate to gold Full backing –Central bank holds at least as much gold as has been issued in banknotes. In the presence of gold inflows the central bank prints money, with gold outflows it retires previously created money. Complete freedom in trade and capital movements –So as not to interfere with the two elements of the adjustment mechanism What factors give automaticity?

39. Feb 03 2004 Euro replaces gold since national central banks are no longer allowed to issue national currencies and there is no exchange rate Within the Euro-zone, when one country runs a balance of payment surplus, it receives an inflow euros, and conversely in the case of a deficit The Hume mechanism is at work in Euroland –A deficit country can no longer use exchange rate to re-establish competitiveness, and adjustments will have to work through prices and wages –The rules of automaticity are part and parcel of Euro area membership How is the Gold Standard related to the EMU?

40. Feb 03 2004 Money starts circulating widely Yet the authorities attempt to continue on with the gold standard but –No agreement on how to set exchange rate between paper currencies –An imbalanced starting point with war legacies High inflation High public debts The interwar period

41. Feb 03 2004 1.The British Case: A refusal to devalue an overvalued currency brings economic decline 2.The French Case: Devaluation, undervaluation and beggar-thy- neighbor policies, until others retaliate and currency becomes overvalued 3.The German Case: Hyperinflation, devaluation and finally, evading the choice of an appropriate exchange rate by resorting to ever widening non-market controls The interwar period: Case studies

42. Feb 03 2004 1.We need a system, one way or another 2.The gold standard – monetary unions – delivers automatic return to equilibrium, but at the cost of booms and Recessions 3.No agreement leads to misalignments, competitive devaluations and trade wars 4.Agreements require “rules of the game”, including a conductor Lessons so far

43. Feb 03 2004 An overriding desire for exchange rate stability –Initially provided by the Bretton Woods system –The US dollar as anchor and the IMF as conductor Once Bretton Woods collapsed, the Europeans were left on their own –The timid Snake arrangement –The European Monetary System –The monetary union Lessons so far
