The efficiency and practicality of currency areas is a controversial source of debate in the field of economics nowadays. Advocates of the system predict that currency unions lead to higher trade volumes as a result of reduced exchange rate uncertainty and higher integration. Possibly the most prominent example of a currency area nowadays is the EMU, initiated in 1995 with the purpose of nurturing a unified European market as one of the main aims. There is no consensus on whether the EMU has induced a net loss or benefit upon its members, but one common finding among academic studies is that the EMU leads to higher trade among union members. The purpose of this study is to evaluate the impact of the euro adoption on trade between EMU members. The model uses a pooled data set comprising the years from 1990 to 2012. Two separate groups are analysed, one including all OECD and EU countries, and another using data from only European countries from the sample. After allowing for different circumstances, I find that two countries belonging to the EMU trade between 17 and 32 per cent more than country pairs outside the union. Moreover, I find that language similarity has a neutral effect in the European sample, while it seems to have a highly significant effect on the sample including all countries.

My dissertation investigates three separate issues pertaining to a country's financial development. The first essay provides an introduction to the three essays. The second essay examines the combined effect of financial development and human capital on economic growth. While both financial development and human capital are individually positively correlated with growth, the literature has not emphasized their combined effect on growth. In this essay, I analyze the extent to which the effect of financial development on growth depends on a country's level of human capital. Using dynamic panel difference and system GMM, as well as the pooled OLS, I find that an increase in human capital decreases the impact of financial development on growth and that countries that lack financial development can achieve greater economic growth through an improvement in human capital. The third essay analyzes how currency unions affect the financial development of a country. This essay tests two forms of asymmetries on the effect of currency unions on financial development; I analyze if currency unions have an equal effect on various forms of financial development, and whether high-income and low-income countries are impacted differently. I find some evidence in favor of both forms of asymmetries with pooled OLS and fixed effect estimation using data on 152 countries and territories over the 1970-2006 time period. The fourth essay tests how financial development affects firms' export market participations and the volume of exports utilizing a firm-level data set which incorporates about 43,500 firms from 80 countries for the time period 2002-2009. Using an instrumental variable approach, I find that a country's financial development negatively affects the extensive margin of trade and positively affects the intensive margin of trade. Furthermore, this study finds that financial development has a disproportionate positive affect on firms with a higher level of external dependence for both margins of trade. Finally, I find that financial development exerts an asymmetric effect on young and mature firms in their export participations but not on the volume of exports.

The switch from a fixed exchange rate regime to a flexible exchange rate regime seldom goes smoothly. A major reason why devaluations are so disruptive is that countries are reluctant to abandon their fixed exchange rate regimes. This “reluctance to devalue” phenomenon is one of the puzzles in international finance. This dissertation makes towards understanding this “reluctance to devalue”. First, I investigate the factors that may influence the probability of a switch from a fixed to a flexible exchange rate regime using survival models. I find that pegs have non-monotonic duration dependence. Moreover, I find that GDP growth strongly influences the probability of abandoning a peg. Second, I propose that the “reluctance to devalue” could stem from uncertainty about the control over inflation after devaluation which raises the threshold of economic pain that could convince policy makers to devalue. I develop this argument in a rules-vs-discretion theoretical framework. Empirical analysis based on survey data from Bulgaria supports this hypothesis. Given that abandoning a fixed exchange rate regime is one of the three options that are available to countries on a peg, I investigate whether a periphery country's decision to abandon its peg is impacted by a potential move to a currency union. I find that the perception of “insurance” justified by expected-bailouts in a currency union increase the support for joining a currency union. The strength of this “safety net” perception is strong despite expected negative impact of the currency union on the country’s macroeconomic indicators.

The theory of optimum currency areas states that the more two countries trade with each other, the better candidates they are for a currency union. In terms of the endogeneity argument, convergence follows from joining a currency union and the integration process itself turns the countries into optimal currency areas. The potential increase in trade is regarded as one of the most important benefits of a currency union. Indirect evidence from studies on the effect of exchange rate volatility on trade does not support this claim. Rose argues that the common currency effect on trade is separate from the effect of the elimination of exchange rate variability and finds a large positive effect of a currency union on trade. Although his methodology has met with criticism, most studies find a positive estimate. A meta-analysis of the studies confirms that a common currency has a statistically and economically significant trade-creating effect. / Economics / M.Com. (Economics)

This thesis studies the history of the Scandinavian Currency Union, 1873-1924. It is divided into four analytical chapters, each dealing with a different aspect of the Union and each written as a separate paper. The conclusions of the thesis challenge existing views of the Union and examines new aspects of this episode in monetary history. It poses new questions and exploits and evaluates new sources. The first paper offers an original interpretation of the role of Scandinavianism in the monetary reform of 1873-1875. It is argued that its importance has been both exaggerated and misinterpreted. In fact, the monetary integration of those years was principally motivated by economic considerations. The second paper deals with inter Scandinavian monetary cooperation during the period 1873-1914. It argues that the process of monetary integration, later followed by disintegration, during these decades is best understood in the context of a trade off between financial efficiency and national economic vulnerability.  It provides a comprehensive analysis of the motives that underlay the principal extensions of the Union’s institutional framework.This includes, the formation, cancellation and renegotiation of the formal, Union based, clearing agreement, as well as the process leading to the free circulation of all Scandinavian notes throughout the currency area.The third paper studies the level of integration and efficiency of the Scandinavian foreign exchange market throughout the period. The paper applies theories and methods from modern economics and finance on a new set of historical financial data. It concludes that the currency union generally, and the clearing agreement in particular, significantly increased the degree of market integration. It also concludes that, during most of the period, the Scandinavian foreign exchange market was characterized by perfect arbitrage and efficiency. The final paper challenges the prevailing scholarly view of the dissolution of the Union. It argues that the break up resulted from the asymmetric shocks that the three countries experienced during World War I. These shocks, which differed as a result of varying national economic policies and structures, created tensions that required exchange rate adjustments to be resolved. / <p>Diss.
