Does it cost to be virtuous? The macroeconomic effects of fiscal constraints

We study whether and how fiscal restrictions alter the business cycle features of macrovariables for a sample of 48 US states. We also examine the typical transmission properties of fiscal disturbances and the implied fiscal rules of states with different fiscal restrictions. Fiscal constraints are characterized with a number of indicators. There are similarities in second moments of macrovariables and in the transmission properties of fiscal shocks across states with different fiscal constraints. The cyclical response of expenditure differs in size and sometimes in sign, but heterogeneity within groups makes point estimates statistically insignificant. Creative budget accounting is responsible for the pattern. Implications for the design of fiscal rules and the reform of the Stability and Growth Pact are discussed.

Price differentials in monetary unions: The role of fiscal shocks

We study the effect of regional expenditure and revenue shocks on price differentials for47 US states and 9 EU countries. We identify shocks using sign restrictions on the dynamicsof deficits and output and construct two estimates for structural price differentials dynamics which optimally weight the information contained in the data for all units. Fiscal shocks explain between 14 and 23 percent of the variability of price differentials both in the US and in the EU. On average, expansionary fiscal disturbances produce positive price differential responses while distortionary balance budget shocks produce negative price differential responses. In a number of units, price differential responses to expansionary fiscal shocks are negative. Spillovers and labor supply effects partially explain this pattern while geographical, political, and economic indicators do not.

Litigation against fracking bans and moratoriums in the US: exit, voice and loyalty

A number of US states, counties and municipalities have responded to the public health and environmental concerns surrounding fracking by imposing bans or moratoriums on unconventional oil and gas drilling. These restrictions have, in recent years, given rise to litigation challenges by oil and gas companies and by property owners deprived of potential revenues. The current article begins by examining precisely who has litigated. Have large companies dominated or is it mostly smaller independents? Is there a difference in litigation rates between private and public companies? The article then considers how Hirschman’s ideas of exit, voice and loyalty might apply in the context of bans and moratoriums and further explores some of the factors that may have driven litigation in the area.

On testing the Phillips curves, the IS Curves, and the interaction between fiscal and monetary policies

Esta tese é composta por três ensaios sobre testes empíricos de curvas de Phillips, curvas IS e a interação entre as políticas fiscal e monetária. O primeiro ensaio ("Curvas de Phillips: um Teste Abrangente") testa curvas de Phillips usando uma especificação autoregressiva de defasagem distribuída (ADL) que abrange a curva de Phillips Aceleracionista (APC), a curva de Phillips Novo Keynesiana (NKPC), a curva de Phillips Híbrida (HPC) e a curva de Phillips de Informação Rígida (SIPC). Utilizamos dados dos Estados Unidos (1985Q1--2007Q4) e do Brasil (1996Q1--2012Q2), usando o hiato do produto e alternativamente o custo marginal real como medida de pressão inflacionária. A evidência empírica rejeita as restrições decorrentes da NKPC, da HPC e da SIPC, mas não rejeita aquelas da APC. O segundo ensaio ("Curvas IS: um Teste Abrangente") testa curvas IS usando uma especificação ADL que abrange a curva IS Keynesiana tradicional (KISC), a curva IS Novo Keynesiana (NKISC) e a curva IS Híbrida (HISC). Utilizamos dados dos Estados Unidos (1985Q1--2007Q4) e do Brasil (1996Q1--2012Q2). A evidência empírica rejeita as restrições decorrentes da NKISC e da HISC, mas não rejeita aquelas da KISC. O terceiro ensaio ("Os Efeitos da Política Fiscal e suas Interações com a Política Monetária") analisa os efeitos de choques na política fiscal sobre a dinâmica da economia e a interação entre as políticas fiscal e monetária usando modelos SVARs. Testamos a Teoria Fiscal do Nível de Preços para o Brasil analisando a resposta do passivo do setor público a choques no superávit primário. Para a identificação híbrida, encontramos que não é possível distinguir empiricamente entre os regimes Ricardiano (Dominância Monetária) e não-Ricardiano (Dominância Fiscal). Entretanto, utilizando a identificação de restrições de sinais, existe evidência que o governo seguiu um regime Ricardiano (Dominância Monetária) de janeiro de 2000 a junho de 2008.

Focal points and fiscal discipline. ACES Cases No. 2013.2

Many studies suggest that balanced budget rules can restrain sovereign debt and lower sovereign borrowing costs, even if those rules are never enforced in court. Typically, this is explained as a result of a legal deterrence logic, in which the threat of judicial enforcement deters sovereigns from violating the rules. By contrast, we argue that balanced budget rules work by coordinating decentralized punishment of sovereigns by bond markets, rather than by posing a credible threat of judicial enforcement. Therefore, the clarity of the focal point provided by the rule, rather than the strength of its judicial enforcement mechanisms, determines its effectiveness. We develop a formal model that captures the logic of our argument, and we assess this model using data on US states. We then consider implications of our argument for the impact of the balanced budget rules recently imposed on eurozone states in the Fiscal Compact Treaty.

Fiscal Federalism in Crisis: Lessons for Europe from the US

The euro area is facing crisis, while the US is not, though the overall fiscal situation and outlook is better in the euro area than in the US, and though the US faces serious state-level fiscal crises. A higher level of fiscal federalism would strengthen the euro area, but is not inevitable. Current fiscal reform proposals (strengthening of current rules, more policy coordination and an emergency financing mechanism) will if implemented result in some improvements. But implementation might be deficient or lack credibility, and could lead to disputes and carry a significant political risk. Introduction of a Eurobond covering up to 60 percent of member states’ GDP would bring about much greater levels of fiscal discipline than any other proposal, would create an attractive Eurobond market, and would deliver a strong message about the irreversible nature of European integration.

The Development of Public Finances and Role of Fiscal Constraints in a Monetary Union: Example eurozone

This thesis is about the development of public debt and deficit in the eurozone, which has been in the center of attention for much of the new millennium. The debt-to-GDP and deficit-to-GDP ratios have changed significantly during the period of the European monetary integration, with sharp increases in the levels since the beginning of the financial crisis. We view the levels both before and after the establishment of the European Central Bank. The subject is complemented by a study of the restrictions on fiscal policy in the eurozone. The thesis begins with a review of the most central agreements in the Economic and Monetary Union, namely the Maastricht Treaty, the Stability and Growth Pact and the Fiscal Compact. We study the instructions and requirements provided by these contracts, with the emphasis being on the debt and deficit values. Furthermore, we view two theories that aim to provide us with information, whether the fiscal restrictions are useful or not. The second and empirical part consists of review on the debt and deficit levels in practice. We take a close look on the values for each of the currency union members. The third and last part summarizes the findings, and analyzes the reasons behind the changes. The result of the thesis is, that even though the levels of public debt and deficit have worsened since the beginning of the financial crisis, tight rules on fiscal policy might not be the best possible solution. Private sector has played a crucial part in the increase of the debt levels, and tight rules have their impact on the long awaited economic growth in the eurozone. It is obvious, though, that some form of fiscal guidelines with scientific ground are needed in order to avoid excessive and harmful debt and deficit levels. The main task is to make these guidelines a more essential part of the fiscal policy in each of the member countries.

Forecasting US bond default ratings allowing for previous and initial state dependence in an ordered probit model

In this paper we investigate the ability of a number of different ordered probit models to predict ratings based on firm-specific data on business and financial risks. We investigate models based on momentum, drift and ageing and compare them against alternatives that take into account the initial rating of the firm and its previous actual rating. Using data on US bond issuing firms rated by Fitch over the years 2000 to 2007 we compare the performance of these models in predicting the rating in-sample and out-of-sample using root mean squared errors, Diebold-Mariano tests of forecast performance and contingency tables. We conclude that initial and previous states have a substantial influence on rating prediction.

Financial crisis and quantitative easing: can broad money tell us anything?

When Bank of England (and the Federal Reserve Board) introduced their quantitative easing (QE) operations they emphasised the effects on money and credit, but much of their empirical research on the effects of QE focuses on long-term interest rates. We use a flow of funds matrix with an independent central bank to show the implications of QE and other monetary developments, and argue that the financial crisis, the fiscal expansion and QE are likely to have constituted major exogenous shocks to money and credit in the UK which could not be digested immediately by the usual adjustment mechanisms. We present regressions of a reduced form model which considers the growth of nominal spending as determined by the growth of nominal money and other variables. These results suggest that money was not important during the Great Moderation but has had a much larger role in the period of the crisis and QE. We then use these estimates to illustrate the effects of the financial crisis and QE. We conclude that it would be useful to incorporate money and/or credit in wider macroeconometric models of the UK economy.

On the dynamic effects of fiscal policy

Dans le sillage de la récession mondiale de 2008-09, plusieurs questions ont été soulevées dans la littérature économique sur les effets à court et à long terme de la politique budgétaire sur l’activité économique par rapport à son signe, sa taille et sa durée. Ceux-ci ont des implications importantes pour mieux comprendre les canaux de transmission et l’efficacité des politiques budgétaires, avec la politique monétaire étant poursuivi, ainsi que pour leurs retombées économiques. Cette thèse fait partie de ce regain d’intérêt de la littérature d’examiner comment les changements dans la politique budgétaire affectent l’activité économique. Elle repose alors sur trois essais: les effets macroéconomiques des chocs de dépenses publiques et des recettes fiscales, les résultats macroéconomiques de l’interaction entre les politiques budgétaire et monétaire et le lien entre la politique budgétaire et la répartition des revenus. Le premier chapitre examine les effets des chocs de politique budgétaire (chocs de dépenses publiques et chocs de recettes fiscales) sur l’économie canadienne au cours de la période 1970-2010, en s’appuyant sur la méthode d’identification des restrictions de signe développée par Mountford et Uhlig [2009]. En réponse à la récession mondiale, les autorités fiscales dans les économies avancées, dont le Canada ont généralement mis en oeuvre une approche en deux phases pour la politique budgétaire. Tout d’abord, ils ont introduit des plans de relance sans précédent pour relancer leurs économies. Par exemple, les mesures de relance au Canada, introduites à travers le Plan d’action économique du Canada, ont été projetées à 3.2 pour cent du PIB dans le budget fédéral de 2009 tandis que l’ "American Recovery and Reinvestment Act"(ARRA) a été estimé à 7 pour cent du PIB. Par la suite, ils ont mis en place des plans d’ajustement en vue de réduire la dette publique et en assurer la soutenabilité à long terme. Dans ce contexte, évaluer les effets multiplicateurs de la politique budgétaire est important en vue d’informer sur l'efficacité de telles mesures dans la relance ou non de l'activité économique. Les résultats montrent que les multiplicateurs d'impôt varient entre 0.2 et 0.5, tandis que les multiplicateurs de dépenses varient entre 0.2 et 1.1. Les multiplicateurs des dépenses ont tendance à être plus grand que les multiplicateurs des recettes fiscales au cours des deux dernières décennies. Comme implications de politique économique, ces résultats tendent à suggérer que les ajustements budgétaires par le biais de grandes réductions de dépenses publiques pourraient être plus dommageable pour l'économie que des ajustements budgétaires par la hausse des impôts. Le deuxième chapitre, co-écrit avec Constant Lonkeng Ngouana, estime les effets multiplicateurs des dépenses publiques aux Etats-Unis en fonction du cycle de la politique monétaire. Les chocs de dépenses publiques sont identifiés comme étant des erreurs de prévision du taux de croissance des dépenses publiques à partir des données d'Enquêtes des prévisionnistes professionnels et des informations contenues dans le "Greenbook". L'état de la politique monétaire est déduite à partir de la déviation du taux des fonds fédéraux du taux cible de la Réserve Fédérale, en faisant recours à une fonction lisse de transition. L'application de la méthode des «projections locales» aux données trimestrielles américaines au cours de la période 1965-2012 suggère que les effets multiplicateurs des dépenses fédérales sont sensiblement plus élevées quand la politique monétaire est accommodante que lorsqu'elle ne l'est pas. Les résultats suggèrent aussi que les dépenses fédérales peuvent stimuler ou non la consommation privée, dépendamment du degré d’accommodation de la politique monétaire. Ce dernier résultat réconcilie ainsi, sur la base d’un cadre unifié des résultats autrement contradictoires à première vue dans la littérature. Ces résultats ont d'importantes implications de politique économique. Ils suggèrent globalement que la politique budgétaire est plus efficace lorsqu'on en a le plus besoin (par exemple, lorsque le taux de chômage est élevé), si elle est soutenue par la politique monétaire. Ils ont également des implications pour la normalisation des conditions monétaires dans les pays avancés: la sortie des politiques monétaires non-conventionnelles conduirait à des multiplicateurs de dépenses fédérales beaucoup plus faibles qu'autrement, même si le niveau de chômage restait élevé. Ceci renforce la nécessité d'une calibration prudente du calendrier de sortie des politiques monétaires non-conventionnelles. Le troisième chapitre examine l'impact des mesures d'expansion et de contraction budgétaire sur la distribution des revenus dans un panel de 18 pays d'Amérique latine au cours de la période 1990-2010, avec un accent sur les deniers 40 pour cent. Il explore alors comment ces mesures fiscales ainsi que leur composition affectent la croissance des revenus des dernier 40 pour cent, la croissance de leur part de revenu ainsi que la croissance économique. Les mesures d'expansion et de contraction budgétaire sont identifiées par des périodes au cours desquels il existe une variation significative du déficit primaire corrigé des variations conjoncturelles en pourcentage du PIB. Les résultats montrent qu'en moyenne l'expansion budgétaire par la hausse des dépenses publiques est plus favorable à la croissance des revenus des moins bien-nantis que celle par la baisse des impôts. Ce résultat est principalement soutenu par la hausse des dépenses gouvernementales de consommation courante, les transferts et subventions. En outre ces mesures d’expansion budgétaire sont favorables à la réduction des inégalités car elles permettent d'améliorer la part des revenus des moins bien-nantis tout en réduisant la part des revenus des mieux-nantis de la distribution des revenus. En outre ces mesures d’expansion budgétaire sont favorables à la réduction des inégalités car elles permettent d'améliorer la part des revenus des moins bien-nantis tout en réduisant la part des revenus des mieux-nantis de la distribution des revenus. Cependant, l'expansion budgétaire pourrait soit n'avoir aucun effet sur la croissance économique ou entraver cette dernière à travers la hausse des dépenses en capital. Les résultats relatifs à la contraction budgétaire sont quelque peu mitigés. Parfois, les mesures de contraction budgétaire sont associées à une baisse de la croissance des revenus des moins bien nantis et à une hausse des inégalités, parfois l'impact de ces mesures est non significatif. Par ailleurs, aucune des mesures n’affecte de manière significative la croissance du PIB. Comme implications de politique économique, les pays avec une certaine marge de manœuvre budgétaire pourraient entamer ou continuer à mettre en œuvre des programmes de "filets de sauvetage"--par exemple les programmes de transfert monétaire conditionnel--permettant aux segments vulnérables de la population de faire face à des chocs négatifs et aussi d'améliorer leur conditions de vie. Avec un potentiel de stimuler l'emploi peu qualifié, une relance budgétaire sage par les dépenses publique courantes pourrait également jouer un rôle important pour la réduction des inégalités. Aussi, pour éviter que les dépenses en capital freinent la croissance économique, les projets d'investissements publics efficients devraient être prioritaires dans le processus d'élaboration des politiques. Ce qui passe par la mise en œuvre des projets d'investissement avec une productivité plus élevée capable de générer la croissance économique nécessaire pour réduire les inégalités.

Between the headlines of the Israeli - Arabic conflict: the coverage of CNN and Al Jazeera

The purpose of this article is to analyze the coverage made by CNN and Al Jazeera (in Arabic) to operation Caste Lead and the Goldstone Report during 2008 and 2009. This investigation is based in the theory of Qualitative Analysis of Content, by Wildemuth and Zhang. The methodology follows up with the one proposed by the authors in the main theory, complementing it with the Gamson and Modigliani´s Framing theory. The methodology mention above display the different in the coverage development, determined by the geopolitical influences; being CNN more influenced by a Western pro USA and pro Israeli speech, while Al Jazeera is more prone to support the Palestinian cause, this is the thesis of this article. During the development of the investigation, the thesis was demonstrated to be only partially accurate as CNN was not completely supportive to the Israeli arguments during the coverage, but Al Jazeera did have preferential speech for the Palestinian cause.

Natural resource windfalls and efficiency of local government expenditures: evidence from Peru

We study the role of natural resource windfalls in explaining the efficiency of public expenditures. Using a rich dataset of expenditures and public good provision for 1,836 municipalities in Peru for period 2001-2010, we estimate a non-monotonic relationship between the efficiency of public good provision and the level of natural resource transfers. Local governments that were extremely favored by the boom of mineral prices were more efficient in using fiscal windfalls whereas those benefited with modest transfers were more inefficient. These results can be explained by the increase in political competition associated with the boom. However, the fact that increases in efficiency were related to reductions in public good provision casts doubts about the beneficial effects of political competition in promoting efficiency.

Modelling, control and supervision for a class of hybrid systems

The aim of this thesis is to narrow the gap between two different control techniques: the continuous control and the discrete event control techniques DES. This gap can be reduced by the study of Hybrid systems, and by interpreting as Hybrid systems the majority of large-scale systems. In particular, when looking deeply into a process, it is often possible to identify interaction between discrete and continuous signals. Hybrid systems are systems that have both continuous, and discrete signals. Continuous signals are generally supposed continuous and differentiable in time, since discrete signals are neither continuous nor differentiable in time due to their abrupt changes in time. Continuous signals often represent the measure of natural physical magnitudes such as temperature, pressure etc. The discrete signals are normally artificial signals, operated by human artefacts as current, voltage, light etc. Typical processes modelled as Hybrid systems are production systems, chemical process, or continuos production when time and continuous measures interacts with the transport, and stock inventory system. Complex systems as manufacturing lines are hybrid in a global sense. They can be decomposed into several subsystems, and their links. Another motivation for the study of Hybrid systems is the tools developed by other research domains. These tools benefit from the use of temporal logic for the analysis of several properties of Hybrid systems model, and use it to design systems and controllers, which satisfies physical or imposed restrictions. This thesis is focused in particular types of systems with discrete and continuous signals in interaction. That can be modelled hard non-linealities, such as hysteresis, jumps in the state, limit cycles, etc. and their possible non-deterministic future behaviour expressed by an interpretable model description. The Hybrid systems treated in this work are systems with several discrete states, always less than thirty states (it can arrive to NP hard problem), and continuous dynamics evolving with expression: with Ki ¡ Rn constant vectors or matrices for X components vector. In several states the continuous evolution can be several of them Ki = 0. In this formulation, the mathematics can express Time invariant linear system. By the use of this expression for a local part, the combination of several local linear models is possible to represent non-linear systems. And with the interaction with discrete events of the system the model can compose non-linear Hybrid systems. Especially multistage processes with high continuous dynamics are well represented by the proposed methodology. Sate vectors with more than two components, as third order models or higher is well approximated by the proposed approximation. Flexible belt transmission, chemical reactions with initial start-up and mobile robots with important friction are several physical systems, which profits from the benefits of proposed methodology (accuracy). The motivation of this thesis is to obtain a solution that can control and drive the Hybrid systems from the origin or starting point to the goal. How to obtain this solution, and which is the best solution in terms of one cost function subject to the physical restrictions and control actions is analysed. Hybrid systems that have several possible states, different ways to drive the system to the goal and different continuous control signals are problems that motivate this research. The requirements of the system on which we work is: a model that can represent the behaviour of the non-linear systems, and that possibilities the prediction of possible future behaviour for the model, in order to apply an supervisor which decides the optimal and secure action to drive the system toward the goal. Specific problems can be determined by the use of this kind of hybrid models are: - The unity of order. - Control the system along a reachable path. - Control the system in a safe path. - Optimise the cost function. - Modularity of control The proposed model solves the specified problems in the switching models problem, the initial condition calculus and the unity of the order models. Continuous and discrete phenomena are represented in Linear hybrid models, defined with defined eighth-tuple parameters to model different types of hybrid phenomena. Applying a transformation over the state vector : for LTI system we obtain from a two-dimensional SS a single parameter, alpha, which still maintains the dynamical information. Combining this parameter with the system output, a complete description of the system is obtained in a form of a graph in polar representation. Using Tagaki-Sugeno type III is a fuzzy model which include linear time invariant LTI models for each local model, the fuzzyfication of different LTI local model gives as a result a non-linear time invariant model. In our case the output and the alpha measure govern the membership function. Hybrid systems control is a huge task, the processes need to be guided from the Starting point to the desired End point, passing a through of different specific states and points in the trajectory. The system can be structured in different levels of abstraction and the control in three layers for the Hybrid systems from planning the process to produce the actions, these are the planning, the process and control layer. In this case the algorithms will be applied to robotics ¡V a domain where improvements are well accepted ¡V it is expected to find a simple repetitive processes for which the extra effort in complexity can be compensated by some cost reductions. It may be also interesting to implement some control optimisation to processes such as fuel injection, DC-DC converters etc. In order to apply the RW theory of discrete event systems on a Hybrid system, we must abstract the continuous signals and to project the events generated for these signals, to obtain new sets of observable and controllable events. Ramadge & Wonham¡¦s theory along with the TCT software give a Controllable Sublanguage of the legal language generated for a Discrete Event System (DES). Continuous abstraction transforms predicates over continuous variables into controllable or uncontrollable events, and modifies the set of uncontrollable, controllable observable and unobservable events. Continuous signals produce into the system virtual events, when this crosses the bound limits. If this event is deterministic, they can be projected. It is necessary to determine the controllability of this event, in order to assign this to the corresponding set, , controllable, uncontrollable, observable and unobservable set of events. Find optimal trajectories in order to minimise some cost function is the goal of the modelling procedure. Mathematical model for the system allows the user to apply mathematical techniques over this expression. These possibilities are, to minimise a specific cost function, to obtain optimal controllers and to approximate a specific trajectory. The combination of the Dynamic Programming with Bellman Principle of optimality, give us the procedure to solve the minimum time trajectory for Hybrid systems. The problem is greater when there exists interaction between adjacent states. In Hybrid systems the problem is to determine the partial set points to be applied at the local models. Optimal controller can be implemented in each local model in order to assure the minimisation of the local costs. The solution of this problem needs to give us the trajectory to follow the system. Trajectory marked by a set of set points to force the system to passing over them. Several ways are possible to drive the system from the Starting point Xi to the End point Xf. Different ways are interesting in: dynamic sense, minimum states, approximation at set points, etc. These ways need to be safe and viable and RchW. And only one of them must to be applied, normally the best, which minimises the proposed cost function. A Reachable Way, this means the controllable way and safe, will be evaluated in order to obtain which one minimises the cost function. Contribution of this work is a complete framework to work with the majority Hybrid systems, the procedures to model, control and supervise are defined and explained and its use is demonstrated. Also explained is the procedure to model the systems to be analysed for automatic verification. Great improvements were obtained by using this methodology in comparison to using other piecewise linear approximations. It is demonstrated in particular cases this methodology can provide best approximation. The most important contribution of this work, is the Alpha approximation for non-linear systems with high dynamics While this kind of process is not typical, but in this case the Alpha approximation is the best linear approximation to use, and give a compact representation.

Effect of Information about benefits of biotechnology on consumer acceptance of genetically modified food; evidence from experimental auctions in the United States, England, and France

This study investigates the effect of information about potential benefits of biotechnology on consumer acceptance of genetically modified (GM) foods. Consumer willingness to accept compensation to consume a GM food was elicited using an incentive compatible auction mechanism in three US states (California, Florida, and Texas) and in two European countries (England and France). Results indicate that information on environmental benefits, health benefits and benefits to the third world significantly decreased the amount of money consumers demanded to consume GM food; however, the effect of information varied by type of information and location. Consistent with prior research, we find that initial attitudes toward biotechnology have a significant effect on how individuals responded to new information.
