Studies on the international effects of real shocks

This doctoral thesis addresses the macroeconomic effects of real shocks in open economies in flexible exchange rate regimes. The first study of this thesis analyses the welfare effects of fiscal policy in a small open economy, where private and government consumption are substitutes in terms of private utility. The main findings are as follows: fiscal policy raises output, bringing it closer to its efficient level, but is not welfare-improving even though government spending directly affects private utility. The main reason for this is that the introduction of useful government spending implies a larger crowding-out effect on private consumption, when compared with the `pure waste' case. Utility decreases since one unit of government consumption yields less utility than one unit of private consumption. The second study of this thesis analyses the question of how the macroeconomic effects of fiscal policy in a small open economy depend on optimal intertemporal behaviour. The key result is that the effects of fiscal policy depend on the size of the elasticity of substitution between traded and nontraded goods. In particular, the sign of the current account response to fiscal policy depends on the interplay between the intertemporal elasticity of aggregate consumption and the elasticity of substitution between traded and nontraded goods. The third study analyses the consequences of productive government spending on the international transmission of fiscal policy. A standard result in the New Open Economy Macroeconomics literature is that a fiscal shock depreciates the exchange rate. I demonstrate that the response of the exchange rate depends on the productivity of government spending. If productivity is sufficiently high, a fiscal shock appreciates the exchange rate. It is also shown that the introduction of productive government spending increases both domestic and foreign welfare, when compared with the case where government spending is wasted. The fourth study analyses the question of how the international transmission of technology shocks depends on the specification of nominal rigidities. A growing body of empirical evidence suggests that a positive technology shock leads to a temporary decline in employment. In this study, I demonstrate that the open economy dimension can enhance the ability of sticky price models to account for the evidence. The reasoning is as follows. An improvement in technology appreciates the nominal exchange rate. Under producer-currency pricing, the exchange rate appreciation shifts global demand toward foreign goods away from domestic goods. This causes a temporary decline in domestic employment.

A Cointegration Approach to Topics in Empirical Macroeconomics (summary section only)

Mikael Juselius’ doctoral dissertation covers a range of significant issues in modern macroeconomics by empirically testing a number of important theoretical hypotheses. The first essay presents indirect evidence within the framework of the cointegrated VAR model on the elasticity of substitution between capital and labor by using Finnish manufacturing data. Instead of estimating the elasticity of substitution by using the first order conditions, he develops a new approach that utilizes a CES production function in a model with a 3-stage decision process: investment in the long run, wage bargaining in the medium run and price and employment decisions in the short run. He estimates the elasticity of substitution to be below one. The second essay tests the restrictions implied by the core equations of the New Keynesian Model (NKM) in a vector autoregressive model (VAR) by using both Euro area and U.S. data. Both the new Keynesian Phillips curve and the aggregate demand curve are estimated and tested. The restrictions implied by the core equations of the NKM are rejected on both U.S. and Euro area data. These results are important for further research. The third essay is methodologically similar to essay 2, but it concentrates on Finnish macro data by adopting a theoretical framework of an open economy. Juselius’ results suggests that the open economy NKM framework is too stylized to provide an adequate explanation for Finnish inflation. The final essay provides a macroeconometric model of Finnish inflation and associated explanatory variables and it estimates the relative importance of different inflation theories. His main finding is that Finnish inflation is primarily determined by excess demand in the product market and by changes in the long-term interest rate. This study is part of the research agenda carried out by the Research Unit of Economic Structure and Growth (RUESG). The aim of RUESG it to conduct theoretical and empirical research with respect to important issues in industrial economics, real option theory, game theory, organization theory, theory of financial systems as well as to study problems in labor markets, macroeconomics, natural resources, taxation and time series econometrics. RUESG was established at the beginning of 1995 and is one of the National Centers of Excellence in research selected by the Academy of Finland. It is financed jointly by the Academy of Finland, the University of Helsinki, the Yrjö Jahnsson Foundation, Bank of Finland and the Nokia Group. This support is gratefully acknowledged.

Fiscal Policy and Economic Stability: Does PIGS stand for Procyclicality In Government Spending?

The Financial Crisis has hit particularly hard countries like Ireland or Spain. Procyclical fiscal policy has contributed to a boom-bust cycle that undermined fiscal positions and deepened current account deficits during the boom. We set up an RBC model of a small open economy, following Mendoza (1991), and introduce the effect of fiscal policy decisions that change over the cycle. We calibrate the model on data for Ireland, and simulate the effect of different spending policies in response to supply shocks. Procyclical fiscal policy distorts intertemporal allocation decisions. Temporary spending boosts in booms spur investment, and hence the need for external finance, and so generates very volatile cycles in investment and the current account. This economic instability is also harmful for the steady state level of output. Our model is able to replicate the relation between the degree of cyclicality of fiscal policy, and the volatility of consumption, investment and the current account observed in OECD countries.

Purchasing power parity versus fixed exchange rate rules: A stability and welfare analysis

This paper evaluates the desirability of PPP rules vis-á-vis fixed exchange rates both in terms of welfare and stability properties. The analysis is conducted within a small open-economy New Keynesian framework extended to include a cost channel. In terms of stability, we find that while the equilibrium is always unique under fixed exchange rates its uniqueness critically depends upon the presence/absence of the cost channel under a PPP rule. Overall, then, in terms of welfare a fixed exchange rate always outperforms a PPP rule.

How the ship of fools was ship-wrecked - The Irish crisis and response

For a decade and half the Irish economy was the poster-boy of Europe. With substantial growth rates, an open economy, flexible labour markets and low levels of taxation, Ireland was seen as evidence of the success of neoliberal policies. Yet in the matter of a few short years Ireland has turned into a one of the peripheral black-holes (along with Greece and Portugal) that are threatening to bring down the whole Eurozone project. Given this context the paper will address two key questions. Firstly how did the much eulogised Celtic Tiger fall so far and so fast? And, secondly, what has been the government’s response to the fall and crash of the Irish economy? These two questions will be addressed through both a general historical analysis of the developments of Irish society up to the crash in 2008 and then the responses to it. Secondly by an analysis of two specific elements of that development; namely the much discussed low corporation tax rate and the failure of social housing to deliver decent affordable homes for those at the bottom of society. The third element is a review of the banking and sovereign debt crisis that led to the IMF/EU deal in November 2010 and a brief outlining of its implications for public finances, especially the question of default. The paper concludes by placing the Irish crisis in a global context.

Pro-internationalisation policies and outward foreign direct investment

This thesis addresses the impacts of public policies on outward foreign direct investment, seeking to contribute to a better understanding of the interplay between pro-internationalisation policies and firm behaviour. Home country measures associated with these policies are explored in terms of use and awareness, as determinants of foreign direct investment, as drivers of policy objectives, in terms of perceived importance and impact in different scenarios of internationalisation. Using a comprehensive database of 441 Portuguese firms, being those that had participated at least in one of the 11 types of public support between 1994 and 2009. The empirical papers presented here reveal a moderating effect of firm capabilities and internationalisation conditions on policy objectives. In fact, firms’ resources and capabilities frame the awareness and use of home country support measures, the existence of public policy determinants of foreign direct investment, the decision to carry out more aggressive modes of entry and the choice of more demanding environments, the impact of policy objectives, and the perceived importance of incentives. In practical terms, the findings of this thesis points that firms’ resources and capabilities are negatively associated with the use of public support, contrasting with awareness, which is found to increase with firms’ resources and capabilities. This insight sheds light on a potential problem of incentives allocation. Our results support the established theorizing about the co-evolution of government and firms' policies, home country measures being found as determinants of foreign direct investment. It is also shown that prointernationalization policies reinforce the firms’ resources and capabilities, which seems to have a positive impact on international growth. An evaluation of public policy, from the foreign direct investor's lens, supports the argument that firms involved in more demanding projects tend to attribute more importance to public supports. Behind the specific and concrete contributions identified in each of the empirical papers, as a whole this thesis makes methodological contributions by introducing the evaluation of impacts of public policies to the field of international business through the firm perspective; these contributions are achieved by taking the pro-internationalisation policies of a small open economy to better understand the impacts of public policies, and by shedding light on co-evolution between resource and institutional-based views.

International Transmission of the Business Cycle in a Multi-Sector Model.

Multi-country models have not been very successful in replicating important features of the international transmission of business cycles. Standard models predict cross-country correlations of output and consumption which are respectively too low and too high. In this paper, we build a multi-country model of the business cycle with multiple sectors in order to analyze the role of sectoral shocks in the international transmission of the business cycle. We find that a model with multiple sectors generates a higher cross-country correlation of output than standard one-sector models, and a lower cross-country correlation of consumption. In addition, it predicts cross-country correlations of employment and investment that are closer to the data than the standard model. We also analyze the relative effects of multiple sectors, trade in intermediate goods, imperfect substitution between domestic and foreign goods, home preference, capital adjustment costs, and capital depreciation on the international transmission of the business cycle.

Termes de l'échange endogènes et cycles économiques réels : une application à la Côte-d'Ivoire

À l’aide d’un modèle de cycles réels, la présente étude vise à expliquer, de façon endogène, les fluctuations des termes de l’échange en Côte-d’Ivoire. Pour ce faire, nous cherchons principalement à répondre aux deux questions suivantes : les chocs d’offre et de demande sur le marché d’exportation suffisent-ils à expliquer les variations des termes de l’échange? Et quelle est leur importance relative dans la dynamique des termes de l’échange? Les résultats montrent que les deux chocs considérés expliquent bien la volatilité des termes de l’échange. Nous avons noté que ces deux sources d’impulsions ont un impact significatif sur les fluctuations économiques en Côte-d’Ivoire.

The Exchange Rate in a Dynamic-Optimizing Current Account Model with Nominal Rigidities: a Quantitative Investigation.

This paper studies a dynamic-optimizing model of a semi-small open economy with sticky nominal prices and wages. the model exhibits exchange rate overshooting in response to money supply shocks. the predicted variability of nominal and real exchange rates is roughly consistent with that of G7 effective exchange rates during the post-Bretton Woods era.

Essays on oil price fluctuations and macroeconomic activity

Dans cette thèse, je me suis intéressé aux effets des fluctuations du prix de pétrole sur l'activité macroéconomique selon la cause sous-jacente ces fluctuations. Les modèles économiques utilisés dans cette thèse sont principalement les modèles d'équilibre général dynamique stochastique (de l'anglais Dynamic Stochastic General Equilibrium, DSGE) et les modèles Vecteurs Autorégressifs, VAR. Plusieurs études ont examiné les effets des fluctuations du prix de pétrole sur les principaux variables macroéconomiques, mais très peu d'entre elles ont fait spécifiquement le lien entre les effets des fluctuations du prix du pétrole et la l'origine de ces fluctuations. Pourtant, il est largement admis dans les études plus récentes que les augmentations du prix du pétrole peuvent avoir des effets très différents en fonction de la cause sous-jacente de cette augmentation. Ma thèse, structurée en trois chapitres, porte une attention particulière aux sources de fluctuations du prix de pétrole et leurs impacts sur l'activité macroéconomique en général, et en particulier sur l'économie du Canada. Le premier chapitre examine comment les chocs d'offre de pétrole, de demande agrégée, et de demande de précaution de pétrole affectent l'économie du Canada, dans un Modèle d'équilibre Général Dynamique Stochastique estimé. L'estimation est réalisée par la méthode Bayésienne, en utilisant des données trimestrielles canadiennes sur la période 1983Q1 à 2010Q4. Les résultats montrent que les effets dynamiques des fluctuations du prix du pétrole sur les principaux agrégats macro-économiques canadiens varient en fonction de leurs sources. En particulier, une augmentation de 10% du prix réel du pétrole causée par des chocs positifs sur la demande globale étrangère a un effet positif significatif de l'ordre de 0,4% sur le PIB réel du Canada au moment de l'impact et l'effet reste positif sur tous les horizons. En revanche, une augmentation du prix réel du pétrole causée par des chocs négatifs sur l'offre de pétrole ou par des chocs positifs de la demande de pétrole de précaution a un effet négligeable sur le PIB réel du Canada au moment de l'impact, mais provoque une baisse légèrement significative après l'impact. En outre, parmi les chocs pétroliers identifiés, les chocs sur la demande globale étrangère ont été relativement plus important pour expliquer la fluctuation des principaux agrégats macroéconomiques du Canada au cours de la période d'estimation. Le deuxième chapitre utilise un modèle Structurel VAR en Panel pour examiner les liens entre les chocs de demande et d'offre de pétrole et les ajustements de la demande de travail et des salaires dans les industries manufacturières au Canada. Le modèle est estimé sur des données annuelles désagrégées au niveau industriel sur la période de 1975 à 2008. Les principaux résultats suggèrent qu'un choc positif de demande globale a un effet positif sur la demande de travail et les salaires, à court terme et à long terme. Un choc négatif sur l'offre de pétrole a un effet négatif relativement faible au moment de l'impact, mais l'effet devient positif après la première année. En revanche, un choc positif sur la demande précaution de pétrole a un impact négatif à tous les horizons. Les estimations industrie-par-industrie confirment les précédents résultats en panel. En outre, le papier examine comment les effets des différents chocs pétroliers sur la demande travail et les salaires varient en fonction du degré d'exposition commerciale et de l'intensité en énergie dans la production. Il ressort que les industries fortement exposées au commerce international et les industries fortement intensives en énergie sont plus vulnérables aux fluctuations du prix du pétrole causées par des chocs d'offre de pétrole ou des chocs de demande globale. Le dernier chapitre examine les implications en terme de bien-être social de l'introduction des inventaires en pétrole sur le marché mondial à l'aide d'un modèle DSGE de trois pays dont deux pays importateurs de pétrole et un pays exportateur de pétrole. Les gains de bien-être sont mesurés par la variation compensatoire de la consommation sous deux règles de politique monétaire. Les principaux résultats montrent que l'introduction des inventaires en pétrole a des effets négatifs sur le bien-être des consommateurs dans chacun des deux pays importateurs de pétrole, alors qu'il a des effets positifs sur le bien-être des consommateurs dans le pays exportateur de pétrole, quelle que soit la règle de politique monétaire. Par ailleurs, l'inclusion de la dépréciation du taux de change dans les règles de politique monétaire permet de réduire les coûts sociaux pour les pays importateurs de pétrole. Enfin, l'ampleur des effets de bien-être dépend du niveau d'inventaire en pétrole à l'état stationnaire et est principalement expliquée par les chocs sur les inventaires en pétrole.

Organized Retail Market Boom and the Indian Society

IT and related services played a major role for India’s current 9.2. GDP growth. Organized retailing in India is one more example for its open economy. The IT industries where able develop a demand for Indian talents all over the world and improved their living standards. It directly impacts only a small minority of Indian population while organized retail affects every single Indian and every sector of Indian society. The paper gives a glimpse of the slow evolution of retail market over the years in India and its contribution for economic growth. The likely positive impact of this revolution in different sectors is enumerated. Paper addresses its ability to manipulate consumption pattern of society, increased customer satisfaction and likely change in the market shares of the different types of sellers. Paper discusses its flip sides like increasing social tension among families below poverty line and greater loss of self employment opportunities by this revolution. The main theme of enquiry of this paper is what it all means for the Indian society.

Estudio de la provincia en el modelo territorial colombiano y su perspectiva frente a los desafíos que impone la Constitución Política de Colombia de 1991

El ordenamiento territorial colombiano es débil y sus entidades territoriales carecen de funciones concretas, siendo un obstáculo para alcanzar los fines que la Constitución de 1991 le impuso al Estado colombiano en el contexto de una economía de mercado. En este sentido, en la presente investigación se realiza un estudio sobre la provincia, como nivel de gobierno entre el municipio y el departamento, presentándola como una posibilidad para fortalecer y articular las iniciativas locales, aumentar la participación política y generar economías a escalas en Colombia. En principio, se hace un análisis del ordenamiento territorial colombiano frente al cumplimiento de los fines del Estado; segundo, se realiza un acercamiento conceptual de la Provincia identificando su correlación con entidades similares en países de Europa y América latina; tercero, se hace un recorrido histórico de la Provincia desde la época de la Conquista hasta la actualidad en la realidad colombiana. Y por último, se hace un estudio del rol de las Provincias en una economía abierta como la colombiana.

Análisis de la crisis financiera de estados unidos (2007-2008) y la crisis de deuda (2011): su relación e impacto sobre uno de los fundamentales de la economía colombiana, la tasa de cambio

Este documento presenta una perspectiva de como una economía pequeña y abierta (en temas comerciales y de inversión) como la colombiana, se ve afectada por choques que sufren economías grandes como la estadounidense. Durante el periodo de estudio la economía de Estados Unidos sufrió dos choques: primero la crisis de las hipotecas subprime en los años 2007-2008; luego la crisis de deuda soberana de Estados Unidos en 2011. Estos dos choques afectaron la economía colombiana. En ambos casos, se puede establecer un hecho clave que detonó las crisis. En el primero, la entrada en el capítulo 11 de protección a bancarrotas por parte de Lehman Brothers, el 15 de septiembre de 2008. En el segundo, el detonante fue la baja de la calificación de la deuda soberana de Estados Unidos por parte de Standard and Poor´s el 5 de agosto de 2011. Estos días claves en las crisis, afectaron los principales índices de la bolsa de Estados Unidos, especialmente los relacionados con la actividad financiera, luego es de suponer que posiblemente también afectaron fundamentales de la economía colombiana como lo es la tasa de cambio peso-dólar (USD/COP). Este documento tiene como objeto principal, establecer el impacto de las crisis Norteamericana de 2007-2008 y de 2011, sobre la economía colombiana, específicamente sobre la tasa de cambio USD/COP. El documento también, analiza las causas que generaron dichas crisis en Estados Unidos, haciendo énfasis en la falta de regulación y control por parte de las instituciones del gobierno en la crisis de las hipotecas subprime. De igual forma se analiza el papel de las firmas calificadoras de riesgo, en la crisis de deuda estadounidense.
