This paper provides an empirical assessment of whether the world economy has become smaller in terms of economic distance over the last decades. We adopt a cross-sectional spatial econometric approach, relating domestic output volatility to (distance-weighted averages of) other countries' output volatility, using a sample of 135 countries and rolling 10-year time windows over the period 1955 to 2006. Using descriptive measures, test statistics, and spatial econometric estimates, we find that cross-country interdependence was virtually insignificant in the early post-war period but has increased strongly from the mid-1960s to the mid-1980s and remained at a high level since then. Results for the most recent period suggest that common shocks to output volatility have a magnified impact and roughly quadruplicate through international spillover effects, which are transmitted through both trade and financial openness.

This paper provides a comprehensive empirical assessment of the relation between the cyclicality of fiscal expenditure policy, output volatility, and economic growth, using a large cross-section of 88 countries over the period 1960 to 2004. Identification of the effects of (endogenous) cyclical expenditure policy is achieved by exploiting the exogeneity of countries political and institutional characteristics, which we find to be relevant determinants of the cyclicality of expenditures. There are three main results: First, both pro- and countercyclical expenditure policy amplify output volatility, much in a way like pure fiscal shocks that are unrelated to the cycle. Second, output volatility, due to variations in cyclical and discretionary fiscal policy, is negatively associated with economic growth. Third, there is no direct effect of cyclicality on economic growth other than through output volatility. These findings advocate the introduction of fiscal rules that limit the use of (discretionary and) cyclical fiscal (expenditure) policy to improve growth performance by reducing volatility.

Since the founding of the People’s Republic of China in 1949, China has experienced ten business cyclical fluctuations. The economic growth was characterized by erratic ups and downs which lasted for several decades. With the economic reform and opening up to the outside world in 1978 as part of Deng Xiaoping’s market-oriented policy, the Chinese economy grew exponentially and the volatility of the GDP growth rate declined significantly. The macroeconomic control policies in the 1980s prevented large fluctuations in the country’s economic development, and smoothed the output volatility further. This study examines the output volatility in China and our result reveals the standard deviation of quarterly output growth rate has declined dramatically. Using the CUSUM squares test and the Quandt-Andrews breakpoint test to identify unknown structure breaks, we identified two structural breaks: 1994:1 towards destabilization and 1998:1 towards stabilization. We then examine the stochastic process for GDP and the result shows that the decrease in volatility can be traced primarily to a decrease in the standard deviation of output shocks. Following this, we reached two other conclusions. First, there is a strong relationship between movements in output volatility and the movements in inflation volatility. Both output and inflation volatilities increased significantly during the third and fourth quarter of 1994 and both dropped sharply after 1996, which followed a similar path over the period. Second, using the standard decomposition of GDP, the decrease in output volatility can be traced to a decrease in the volatility of consumption, investment, and net export, especially rural consumption expenditure and residential investment.

This thesis investigates why and how macroeconomic volatility in source countries interacts with their FDI outflows. The study focuses on FDI flowing out from OECD countries to less developed countries in the ASEAN region. Using a panel data encompassing 52 country-pairs over the period 1996-2011, I find a negative correlation between FDI outflows and macroeconomic volatility in source countries. More specifically the empirical results suggest an adverse relationship between inflation and output volatility (business cycles fluctuations) and FDI flows – the more macroeconomic volatility in developed economies the lesser FDI flows to less developed economies, which is explained by Keynesian theories. These findings derive from a gravity model approach, which enabled me to control for host country determinants. In order to estimate these relationships I adopted a random effects model and a tobit model. The reason behind the use of these two models derives from the different views within this branch of research because of censored FDI statistics. The thesis is inspired by Éric Rougier’s et al. work on how macroeconomic volatility in European countries interacts with FDI flows to the MENA region (2012).

By analyzing the behavior of the variables that constitute the output, its components and determinants, this work seeks to show the reasons of this significant drop in output volatility during the considered period. Low output volatility brings positive consequences for society welfare, for income distribution and for long term growth. Several studies have been written to point out the causes of the decline in output volatility in different countries over the last two decades, a phenomenon that has been called as 'The Great Moderation' in the United States. Considering the benefits of this process, understanding their causes is indispensable for defining economic policies that guarantees the sustainability of moderated economic cycles. This work focuses on the importance of nominal factors (demand shocks) to explain the decline of Brazilian output volatility. On the hand, the absence of external restrictions for economic growth and the last worldwide prosperity cycle represent the contribution of the external portion. On the other hand, better practices of macroeconomic policies respond for the internal causes. / O presente trabalho analisa o comportamento da volatilidade do crescimento do produto brasileiro entre 1980 e 2008, cuja trajetória apresenta um declínio de 70% desde 1991. Através da análise do comportamento do PIB, de seus componentes e de seus determinantes, objetiva-se apontar as razões pela qual a volatilidade do crescimento caiu de forma significativa no período considerado. A baixa volatilidade do crescimento do produto traz conseqüências positivas para o bem-estar da sociedade, para a distribuição de renda e para o crescimento econômico de longo prazo. Diferentes estudos foram realizados para apontar as causas do declínio desta volatilidade em diversos países nas últimas três décadas, fenômeno que nos Estados Unidos passou a ser conhecido como The Great Moderation. Dados os benefícios deste processo, entender as suas razões é imprescindível para a formulação de políticas econômicas que garantam a sustentabilidade da moderação dos ciclos econômicos. Este trabalho concentra-se nos fatores nominais (choques de demanda) para explicar o processo de redução da volatilidade do crescimento brasileiro. De um lado, a ausência de restrições externas ao crescimento econômico e o ciclo de prosperidade mundial dos últimos cinco anos garantiram a contribuição da parcela externa. Por outro lado, a condução de políticas macroeconômicas mais sólidas, refletindo em uma maior estabilidade de variáveis como o nível de preços, respondem pelos fatores internos.

Cette thèse s’articule autour de trois chapitres indépendants qui s’inscrivent dans les champs de la macroéconomie, de l’économie monétaire et de la finance internationale. Dans le premier chapitre, je construis un modèle néo-keynesien d’équilibre général sous incertitude pour examiner les implications de la production domestique des ménages pour la politique monétaire. Le modèle proposé permet de reconcilier deux faits empiriques majeurs: la forte sensibilité du produit intérieur brut aux chocs monétaires (obtenue à partir des modèles VAR), et le faible degré de rigidité nominale observé dans les micro-données. Le deuxième chapitre étudie le role de la transformation structurelle (réallocation de la main d’oeuvre entre secteurs) sur la volatilité de la production aggregée dans un panel de pays. Le troisième chapitre quant à lui met en exergue l’importance de la cartographie des échanges commerciaux pour le choix entre un régime de change fixe et l’arrimage à un panier de devises. "Household Production, Services and Monetary Policy" (Chapitre 1) part de l’observation selon laquelle les ménages peuvent produire à domicile des substituts aux services marchands, contrairement aux biens non durables qu’ils acquièrent presque exclusivement sur le marché. Dans ce contexte, ils procèdent à d’importants arbitrages entre produire les services à domicile ou les acquerir sur le marché, dépendamment des changements dans leur revenu. Pour examiner les implications de tels arbitrages (qui s’avèrent être importants dans les micro-données) le secteur domestique est introduit dans un modèle néo-keyenesien d’équilibre général sous incertitude à deux secteurs (le secteur des biens non durables et le secteur des services) autrement standard. Je montre que les firmes du secteur des services sont moins enclin à changer leurs prix du fait que les ménages ont l’option de produire soit même des services substituts. Ceci se traduit par la présence d’un terme endogène supplémentaire qui déplace la courbe de Phillips dans ce secteur. Ce terme croit avec le degré de substituabilité qui existe entre les services produits à domicile et ceux acquis sur le marché. Cet accroissement de la rigidité nominale amplifie la sensibilité de la production réelle aux chocs monétaires, notamment dans le secteur des services, ce qui est compatible avec l’évidence VAR selon laquelle les services de consommation sont plus sensibles aux variations de taux d’intérêt que les biens non durables. "Structural Transformation and the Volatility of Aggregate Output: A Cross-country Analysis" (Chapitre 2) est basée sur l’évidence empirique d’une relation négative entre la part de la main d’oeuvre allouée au secteur des services et la volatilité de la production aggrégée, même lorsque je contrôle pour les facteurs tels que le développement du secteur financier. Ce resultat aggregé est la conséquence des développements sectoriels: la productivité de la main d’oeuvre est beaucoup plus volatile dans l’agriculture et les industries manufacturières que dans les services. La production aggregée deviendrait donc mécaniquement moins volatile au fur et à mesure que la main d’oeuvre se déplace de l’agriculture et de la manufacture vers les services. Pour évaluer cette hypothèse, je calibre un modèle de transformation structurelle à l’économie américaine, que j’utilise ensuite pour générer l’allocation sectorielle de la main d’oeuvre dans l’agriculture, l’industrie et les services pour les autres pays de l’OCDE. Dans une analyse contre-factuelle, le modèle est utlisé pour restreindre la mobilité de la main d’oeuvre entre secteurs de façon endogène. Les calculs montrent alors que le déplacement de la main d’oeuvre vers le secteur des services réduit en effet la volatilité de la production aggregée. "Exchange Rate Volatility under Alternative Peg Regimes: Do Trade Patterns Matter?" (Chapitre 3) est une contribution à la litterature économique qui s’interesse au choix entre divers regimes de change. J’utilise les données mensuelles de taux de change bilatéraux et de commerce extérieur entre 1980 et 2010 pour les pays membre de l’Union Economique et Monétaire Ouest Africaine (UEMOA). La monnaie de ces pays (le franc CFA) est arrimée au franc Francais depuis le milieu des années 40 et à l’euro depuis son introduction en 1999. Au moment de l’arrimage initial, la France était le principal partenaire commercial des pays de l’UEMOA. Depuis lors, et plus encore au cours des dix dernières années, la cartographie des échanges de l’union a significativement changé en faveur des pays du groupe des BICs, notamment la Chine. Je montre dans ce chapitre que l’arrimage à un panier de devises aurait induit une volatilité moins pronnoncée du taux de change effectif nominal du franc CFA au cours de la décennie écoulée, comparé à la parité fixe actuelle. Ce chapitre, cependant, n’aborde pas la question de taux de change optimal pour les pays de l’UEMOA, un aspect qui serait intéressant pour une recherche future. / This thesis includes three independent essays in the fields of macroeconomics, monetary economics and international finance. In the first essay, I build a new Keynesian DSGE model to examine the implications for monetary policy of household production. The proposed theory helps reconcile the relatively strong response of output to monetary policy shocks as suggested by VAR-based evidence and the low degree of price rigidity found in micro data. The second essay analyzes the role of structural transformation (the reallocation of labor across sectors overtime) in shaping the volatility of aggregate output across countries. Finally, the third essay illustrates the importance of trade patterns in choosing between a single currency peg and a peg to a composite basket of currencies. “Household Production, Services and Monetary Policy” (Chapter 1) builds on the observation that consumer services (unlike consumer nondurable) have close substitutes at home. Households may therefore switch between consuming home and market service as the real wage (the opportunity cost of working at home) changes. To study the implications of this arbitrage for monetary policy, I embed a household sector into an otherwise standard two-sector (a nondurable good sector and a service sector) new Keynesian DSGE model. The fact that households are able to produce services at home makes service sector’s firms more reluctant to change their price. This translates into an extra endogenous shift term in the new Keynesian Phillips that is increasing with the extent of substitutability between home and market services. This increased nominal rigidity endogenously amplifies the output response to monetary policy shock, especially in the service sector, which is consistent with VAR-based evidence in the paper that consumer services are more interest-rate sensitive than consumer nondurables. “Structural Transformation and the Volatility of Aggregate Output: A Cross-country Analysis” (Chapter 2) is based on the evidence of a negative relationship between the employment share of the service sector and the volatility of aggregate output, which I obtain after controlling for several factors (including the level of financial development). This aggregate result is driven by sectoral labor productivity differentials: Labor productivity is substantially more volatile in agriculture and manufacturing than in services. Aggregate output would therefore become mechanically more stable as labor shifts away from agriculture and manufacturing, and toward the service sector. To quantify this conjecture, I first calibrate a model of structural transformation (secular reallocation of labor across sectors) to the U.S. economy, which I use to match the time path of labor shares in agriculture, manufacturing and services across OECD countries. The model is subsequently used to conduct a set of counterfactual experiments in which labor is endogenously constrained from moving across sectors. Computations suggest that the shift of labor toward the services sector is indeed volatility-reducing. “Exchange Rate Volatility under Alternative Peg: Do Trade Patterns Matter?” (Chapter 3) is a contribution to the literature on the choice of exchange rate regimes. I use monthly bilateral exchange rate and external trade data from 1980 to 2010 for the member countries of the Western African and Monetary Union (WAEMU). These countries have their common currency (the CFA franc) pegged to the French franc since the mid-40s and to the euro since its introduction in 1999. At the time of the initial peg arrangement, France accounted for most of the external trade of WAEMU countries. Since then, and more notably since the early 2000s, the trade patterns of these countries shifted briskly away from France and other Euro area countries and towards the BICs (China in particular). The chapter finds that a peg to a composite basket of currencies would have led to a less volatile effective exchange rate over the last decade compare to the current hard peg. This chapter, however, does not derive an optimal exchange rate for WAEMU countries, which is an important area for further research.
