Chen, Nai-Wei (2005-11). Two essays on monetary union and international finance. Doctoral Dissertation.
This dissertation studies the Economic and Monetary Union (EMU) and its effects on foreign exchange markets and corporate cash holdings. These two potential effects are examined in the dissertation in two separate essays. The first essay examines the validity of the purchasing power parity (PPP) condition during three distinct exchange rate regimes (floating-rate, target-zone arrangement, and fixed-rate or common currency) from January 1973 through January 2004. My results support PPP, but I find that PPP during the common currency regime holds in fewer EMU countries than during the alternative exchange rate regimes. In addition, PPP between currency blocs holds for all countries examined during the first two regimes, but deteriorates after the introduction of the euro for the EMU countries as opposed to the non-EMU countries. I do not obtain strong evidence supporting PPP for the EMU countries since the euro adoption, but the faster mean reversion I observe in the few EMU countries where PPP does hold, may signal higher market efficiency and economic integration in the future. The second essay investigates corporate liquidity (cash holdings of firms) from 15 European Union (EU) countries [12 Economic and Monetary Union (EMU) countriesthat adopted the euro, and 3 non-EMU countries] from 1993 to 2002 using a dynamic panel data model. My main contributions to the corporate liquidity literature are fourfold. First, I provide evidence that creditor rights also affect corporate liquidity and their effect is more consistent than that of shareholder rights. Second, I show that the recent formation of EMU affects corporate liquidity. Debt and net working capital are better substitutes for cash in EMU countries than non-EMU countries. The adoption of a common currency reduces cash holdings in EMU countries. Third, my results suggest that agency theory plays an important role in explaining corporate liquidity. In particular, the agency view explains corporate liquidity better for EMU firms, probably because of an enhanced capital market integration that weakens the transaction and precautionary motives of holding cash. Fourth, I show that dealing with the endogeneity problem in corporate liquidity studies is important.
