Interactions between macroeconomic fundamentals and term structure of interest rates be stronger according to the way of changes in structure of worldwide economy. Combined macro-finance analysis determines the joint dynamics of term structure of interest rates and macroeconomic fundamentals. This thesis provides analysis of two existing macro-finance models and an original one. Parameter estimations for these three macro-finance term structure models are done for monthly Turkish data by use of an efficient recursive estimator Kalman filter. In spite of the small scale application the results are satisfactory except first model but with longer sets of macroeconomic variables and interest rate data models provide more encouraging results.

This thesis aims to contribute in the field of exchange rate determination. Firstly, it sums results of previous studies (theoretical as well as empirical ones). Consequently, it investigates two approaches to exchange rate determination, and compares their theoretical and empirical performance. Firstly, monetary model is introduced, and secondly 'news' model is presented. Since 'news' model incorporates rational expectations and considers interest rate endogenous, it is expected to give better results in comparison with monetary model. Six exchange rates were chosen for the empirical analysis. They are analyzed in period July 2000 -- June 2012. As expected, 'news' model outperforms monetary model. However, since the volatility of exchange rate is much bigger in reality than both of the models are able to explain, neither of the models can be considered as satisfactory. It is the same result which has been presented in older studies that investigated these models.

La globalisation est probablement la caractéristique principale de l'économie mondiale du 21e siècle. Elle se traduit notamment par l'intégration par les canaux commerciaux, financiers et les marchés de matières premières. Si un tel contexte affecte de manière très significative tous les types d'économies, il convient de souligner que les petites économies ouvertes dépendantes des exportations de matières premières, et ouvertes aux marchés financiers globaux, sont en général les plus exposées. L'économie chilienne possède toutes ces caractéristiques. C’est dans ce contexte que cette thèse explore l'efficacité de la politique budgétaire chilienne et les effets des prix des matières premières et des chocs financiers internationaux sur le PIB chilien et d'autres variables macro-économiques importantes. A cette fin, on utilise une approche empirique basée sur des modèles vectoriels autorégressifs. / The economic globalization is probably the main feature of the 21st century world economy, with economic integration and interdependence of national economies across the world particularly common in commodity and financial markets. Such a context greatly affect all types of economies though those small, dependent on commodity exports, and open to global financial markets are usually the most exposed. Having in mind this scenario, in this Ph.D. dissertation we explore the effectiveness of the Chilean fiscal policy and the effects of commodity prices and foreign financial shocks, on the Chilean GDP and other macroeconomic fundamentals using an empirical approach based on alternative vector autoregressive models.To understand the effectiveness of the country’s fiscal policy aiming at guarantying macroeconomic stability, in the Chapter 1 of this Ph.D. dissertation we study the dynamic effects of fiscal policy on the Chilean macroeconomic fundamentals and the size of fiscal multipliers. Chapter 2 examines how shocks to commodity prices affect the Chilean economic output, fiscal accounts and private consumption, based on correlations analysis and vector autoregression models. In the Chapter 3 of this Ph.D. dissertation we study the effect of foreign financial shocks on the Chilean real economy.

This dissertation consists of three essays, each examining distinct dimensions of cross-sectional variation in exchange rate changes and currency returns conditional on macroeconomic variables. Chapter 2: Protectionism, Bilateral Integration, and the Cross-Section of Ex-change Rate Returns in US Presidential Debates We study the impact of US presidential election TV debates on intraday exchange rates of 96 currencies from 1996 to 2016. Expectations about protectionist measures are the main transmission channel of debate outcomes. Currencies of countries with high levels of bilateral foreign trade with the US depreciate if the election probability of the protectionist candidate increases during the debate. We rationalize our results in a model where a debate victory of a protectionist candidate raises expectations about future tariffs and reduces future net exports to the US, resulting in relative depreciation of currencies with high bilateral trade integration. Chapter 3: Global Portfolio Network and Currency Risk Premia External portfolio investments of countries can explain cross-sectional variation in currency risk premia. Using bilateral portfolio holdings of 26 countries from 2001 to 2021, I construct a network centrality measure where a country is central if it is integrated with key countries that account for a large share in the supply of tradeable financial assets. I find that currency excess returns and interest rates decrease in network centrality. The network centralities are persistent over time and offer a country-specific economic source of risk that are able to explain robust differences in currency risk premia. Empirical asset pricing tests show that the derived risk factor is priced in a cross-section of currency portfolios. Further, negative global shocks cause currencies of central countries to appreciate, while currencies of peripheral countries depreciate. I discuss the findings with implications of a consumption-based capital asset pricing model where central countries have lower consumption growth in high marginal utility states, resulting in an appreciation of their currencies. Chapter 4: FX Dealer Constraints and External Imbalances We study the impact of FX dealer banks' financial health on the cross-sectional variation of exchange rates. Using individual balance sheet information of 39 dealers, we derive an intermediary constraints index that captures the risk-bearing capacity of intermediaries. A deterioration of the solvency of dealer banks impairs their risk-bearing capacity and increases their marginal value of wealth. We test the theoretical prediction of Gabaix and Maggiori (2015) that tightening financial constraints of intermediaries are associated with increasing currency risk premia in the cross-section of the riskiness of currencies, as measured by the net foreign assets of countries. We combine dealer-specific risks to macroeconomic fundamentals of a cross-section of currencies, i.e., the indebtedness to foreigners measured by countries' net foreign assets. We show that currency excess returns increase with a country's external imbalances when constraints are relaxed, but debtor currencies experience a depreciation when constraints tighten.
