Study IIIntersectoral Wage Linkages in Sweden The purpose of this study is to investigate whether the wage-setting in certain sectors of the Swedish economy affects the wage-setting in other sectors. The theoretical background is the Scandinavian model of inflation, which states that the wage-setting in the sectors exposed to international competition affects the wage-setting in the sheltered sectors of the economy. The Johansen maximum likelihood cointegration approach is applied to quarterly data on Swedish sector wages for the period 1980:1–2002:2. Different vector error correction (VEC) models are created, based on assumptions as to which sectors are exposed to international competition and which are not.

Study IIIWage and Price Determination in the Private Sector in Sweden The purpose of this study is to analyse wage and price determination in the private sector in Sweden during the period 1980–2003. The theoretical background is a variant of the “Imperfect competition model of inflation”, which assumes imperfect competition in the labour and product markets. According to the model wages and prices are determined as a result of a “battle of mark-ups” between trade unions and firms. The Johansen maximum likelihood cointegration approach is applied to quarterly Swedish data on consumer prices, import prices, private-sector nominal wages, private-sector labour productivity and the total unemployment rate for the period 1980:1–2003:3. The chosen cointegration rank of the estimated vector error correction (VEC) model is two. Thus, two cointegration relations are assumed: one for private-sector nominal wage determination and one for consumer price determination. The estimation results indicate that an increase of consumer prices by one per cent lifts private-sector nominal wages by 0.8 per cent. Furthermore, an increase of private-sector nominal wages by one per cent increases consumer prices by one per cent. An increase of one percentage point in the total unemployment rate reduces private-sector nominal wages by about 4.5 per cent. The long-run effects of private-sector labour productivity and import prices on consumer prices are about –1.2 and 0.3 per cent, respectively. The Rehnberg agreement during 1991–92 and the monetary policy shift in 1993 affected the determination of private-sector nominal wages, private-sector labour productivity, import prices and the total unemployment rate. The “offensive” devaluation of the Swedish krona by 16 per cent in 1982:4, and the start of a floating Swedish krona and the substantial depreciation of the krona at this time affected the determination of import prices.

Studies of the value relevance of accounting number in capital market research are consistent with the simple view that, in equilibrium, book values are equal to or have some long-term relationship with market values, and that market returns are related to book returns. This dissertation examines the value relevance of annually-reported book values of net assets, earnings and dividends to the year-end market values of five Japanese firms between 1950 and 2004 (a period of 54 years). Econometric techniques are used to develop dynamic models of the relationship between markets, book values and a number of macro-economic variables. In constructing the models, the focus is to provide an accurate statistical description of the underlying relationships between market and book value. It is expected that such research will add to the body of knowledge on factors that are influential to Japanese stock prices. The significant findings of the study are as follows: 1) well-specified models of the data generating process for market value based on the information set used to derive the models are log-linear in form. Additive, linear models in untransformed variables are not well-specified and forecast badly out of sample; 2) the book value of net assets has relevance for market value in the five Japanese firms examined, in the long run.

In capital market research (CMR) studies of the value relevance of accounting numbers are founded upon the concept that, in equilibrium, the book values are equal to or have some long-term relationship with the market value and that market returns are related to book returns. This thesis seeks to resolve a gap in the CMR by examining 30 selected individual firms listed on the Australian stock market during the period 1950 to 2004, using equilibrium correction modelling techniques. Even these limited prior works used cross-sectional techniques rather than the long-run, time-series, analysis used in this study. Moreover, dynamic analysis in the CMR has tended to focus on indexes or portfolio data rather than using firm-specific case study data of the type modelled here. No prior research has taken this approach using Australian data. The results of this thesis indicated that an equilibrium correction relationship between market values and book values for firms listed on the Australian Stock Exchange (ASX) could be determined by using accounting and macroeconomic regressors. The findings of the thesis were consistent with the literature in terms of the variables suggested and important in the firm's valuation from the three main approaches, the analysts (industry) approach, the finance and accounting theory (textbook) approach and the CMR literature approach. The earnings, dividends and book value variables are significant in their relationships with the firm's market values. The models constructed were typically more informative and had an increased forecasting performance compared with the a priori models tested, based on theory and the literature.

This work deals with the demand for money theories and applications of error correction Models and VAR models for the demand for money in the Czech Republic. In the theoretical part of the work are discussed theory of demand for money, with an emphasis on Patinkins theory of demand for money and the wording of VAR models and error correction models. In the application part are applied VAR (1), VAR (2) models and error correction models on the demand for money in the Czech Republic. Data used in the work come from the information system CNB and the CZSO.

This study aims to identify the effects of oil income on economic growth in Iran over the period 1955-2014. The empirical literature indicates that countries with natural resources are growing more slowly than their counterparts. However, the results from this literature are far from conclusive, particularly in regard to the role played by oil-rich countries. Needless to say, this role depends on other factors as well, including the political situation in the country, the quality of institutions, and the efficacy of the financial system. Some empirical research has found that natural resources, particularly oil, can have a positive impact on the output of a country. although natural resources are not a factor of production in growth theories, studies have used different growth frameworks in order to discover whether having natural resources is a blessing or a curse. In line with recent studies, this work uses an augmented neoclassical growth model to develop a theoretical framework where oil enters the long-term output of the country through saving and investment. Overall, the results suggests that oil income has a positive impact on the level of output per capita in Iran. The findings of the econometric results are in line with the historical analysis of the study. Since different methods and proxies were used, a total of eight models were estimated. Interestingly, when PRIVY is used as an index of financial development, the result of the study changes and oil no longer has a significant impact on the economy. However, this can be translated to an inefficient allocation of credit to the private sector.

Para realizar esta análise, foi utilizado o modelo sugerido por Banerjee e Marcellino (2009), o FAVECM, que consiste em agregar o mecanismo de correção de erros ao modelo proposto por Bernanke, Boivin e Eliasz (2005), o FAVAR. A hipótese é que o FAVECM possuiu uma formulação teórica mais geral. Os resultados mostram que para o mercado brasileiro o FAVECM apresentou ganhos significativos de previsão para as taxas mais longas e horizontes de previsão maiores. / The objective of the present work is to examine if the model that combines error correction and factors extracted from large macoeconomic data sets offers a higher forecasting accuracy of the interest rate in Brazil when compared to VAR, VECM and FAVAR. In order to conduct this analysis it was used the econometric methodology introduced by Banerjee and Marcellino (2009), the FAVECM, which allows for the inclusion of error correction terms in the model introduced by Bernanke, Boivin and Eliasz (2005), the FAVAR. The hypothesis is that the FAVECM has several conceptual advantages given it is a nesting (or has a more general) specification. The results show that, for the Brazilian market, the FAVECM presented significant gains in forecasts for longer maturity rates and for longer prevision horizons.

This study investigates the validity of the twin deficits hypothesis for the Turkish quarterly data over the 1988:1-2005:2 periods. To this end, we consider a VAR variable space containing budget deficits, current account deficits, real output, real interest rates and real exchange rates and employ cointegration, equilibrium/error correction mechanism techniques along with Granger-non-causality tests and impulse response analyses. The empirical results from decompositions of the budget and current account deficits into their cyclical and structural components suggest that both CAD and BD are counter-cyclical. The twin deficit hypothesis, consistent with the conventional Mundell-Flemming framework, postulates that current account and budget deficits move together in the long run and the causality runs from the former to the latter. The results from Engle-Granger and Johansen cointegration procedures support either the twin divergence or the Ricardian equivalence postulations but not the twin deficits hypothesis. Current account deficits and budget deficits are also found to be jointly endogenous. The short-run impacts of budget deficits on current account deficits are found to be mainly through the real exchange rate and real interest rate channels.

Studies of the relationship between market values and accounting numbers have long been a part of an established theme in capital markets research (CMR). These studies have taken various forms, most being conducted on a cross sectional basis, tied closely with the assumptions of equilibrium behaviour and efficient markets. Explanatory variables for market value have been dominated by firm-specific variables without incorporating macroeconomic variables. Recently, however, some studies have employed macroeconomic variables and dynamic specification in assessing the relationship between market values and accounting numbers (e.g. Bilson et al. 2001, Nissim and Penman, 2003, and Willett, 2003). The objective of this thesis is to investigate the nature of the relationship between share prices and accounting numbers on the Jakarta Stock Exchange for the period 1992-2002, using dynamic modelling principles in addition to the more usual cross sectional analysis. The approach to regression modelling (general-to-specific strategy)incorporated in this thesis relies less heavily than most CMR on prior economic theories of equilibrium behaviour. Apart from these novel aspects of approach and method, the study also provides valuable information about the emerging financial markets of Indonesia. The results of this thesis show that cointegration and the accompanying equilibrium correction relationship between market and book values for firms listed on the Jakarta Stock Exchange (JSX) can often be identified using accounting and macroeconomic regressors. The models are typically more informative, plausible and consistent than cross sectional models and are useful in interpreting the context in which the market to book relationship exists in Indonesia. A possibly surprising result is that in Indonesia, compared to similar models estimated using US data, the book value of net assets seems to have a stronger relationship with market value. This may be a function of the relative importance of financial statements as a source of information on the JSX.

Le tourisme première industrie mondiale, avec 1186 millions d’arrivées internationaux en 2015, est reconnu comme secteur prioritaire de développement des pays les moins avancés, à travers ses effets directs, indirects et induits. La Tunisie a opté depuis la fin des années 60 pour se développer à travers des activités touristiques. Depuis le début des années 70, le tourisme représente un secteur clef de l’économie tunisienne, le taux de couverture du déficit de la balance des paiements a atteint 97.7% en 1988. Toutefois et depuis le début des années 2000, le tourisme tunisien, souffre d’une image de marque de basse qualité, d’une forte dépendance vis-à-vis du marché européen, et des grands Tours Opérateurs et d’un manque de diversification. Les performances de ce secteur longtemps considéré comme vecteur de croissance économique, semblent être surestimées.Pour dépasser ces problèmes, depuis la fin des années 80, l’État a choisi une stratégie nationale de diversification à travers la mise en tourisme du Sud de la Tunisie. Actuellement, cette partie du pays est devenue une zone touristique de haut standing avec, notamment, un terrain de golf de 150 hectares et un aéroport international. Toutefois, le choix d’un développement axé sur les activités touristiques suscite des inquiétudes, vu les caractéristiques du milieu saharien, et la façon dont le tourisme saharien est commercialisé.Cette thèse a pour objet d'étudier du point de vue de l'analyse économique et d'évaluer la pertinence des choix stratégiques qui ont été faits dans le secteur du tourisme, notamment en zone saharienne, en tenant compte de la nature du milieu caractérisé par un climat aride. L’impact économique, environnemental et social du tourisme sur ces milieux fragiles pourrait être particulièrement critique.Du point de vue économique: d’un côté, ce choix correspond à une marchandisation d’un stock naturel épuisable, dont l’existence est conditionnée par l’accès à l’eau, ce qui a créé des situations de concurrence et de conflits d’usage de la ressource entre les deux secteurs touristique et agricole. D’un autre côté, la courte durée de séjour qui ne dépasse pas les 1.3 jours, peut limiter les retombées positives du tourisme dans ces régions.Du point de vue de l’environnement: le caractère rival mais non exclusif de l’eau le situerait dans la catégorie des « biens communs » dont la disponibilité peut être influencé par les « effets de masse », ce qui nous conduit à envisager un risque de « tragédie des communs ».Sur le plan social: à côté des distorsions sociales qui peuvent naître face à des situations de conflits d’usage autour de la ressource, les emplois crées dans le secteur sont saisonniers peu qualifiés, ce qui peut nuire à un vrai processus de développement local dans ces régions.Dans nos analyses, nous avons utilisé plusieurs outils et approches méthodologiques de caractères théoriques et empiriques dans un cadre macroéconomique. Nous avons mobilisé essentiellement les techniques de cointégration et les modèles à correction d’erreur adaptés à l’étude des séries temporelles en plus des analyses statistiques, sur la période 1970- 2014. / Tourism, the world's leading industry with 1186 million international arrivals in 2015, is recognized as the priority sector of development of the LCDs (Least Developed Countries) through its direct, indirect and induced effects. Since the late 1960s, Tunisia has opted for a development strategy based on tourism activities. Since the early 1970s, tourism has been a key sector of the Tunisian economy: the deficit’s rate of coverage of the payments’ balance reached 97.7% in 1988. However, since the early 2000s, Tunisian tourism suffers from a low quality brand image, a strong dependence on the European market and major tour operators and a lack of diversification. The achievements of this sector, which has been for a long time considered as a vector of economic growth, seem to be overestimated.To overcome these problems, the State has chosen, since the late 1980s, a national strategy of diversification through the setting in tourism of Southern Tunisia. Currently, this part of the country became a tourist area of high standards including a golf course of 150 hectares and an international airport. However, the choice of tourism-oriented development is of concern, given the characteristics of the Saharan environment and the way in which Saharan tourism is marketed.This thesis aims to analyze, from an economic point of view, and to evaluate the suitability and relevance of the strategic choices which have been made in the tourism sector, particularly in the Saharan zone, taking into account the nature of the milieu characterized by an arid climate. The economic, environmental and social impact of tourism on these fragile environments could be particularly critical.Economically: on the one hand, this choice corresponds to a commodification of an exhaustible natural stock, whose existence is conditioned by access to water, which has created rivalry and conflicts in the use of the resource between the two sectors, namely, tourism and agriculture. On the other hand, the short duration of stay which does not exceed on average 1.3 days, can limit the positive fallout of tourism in these regions.Environmentally: the rival but not exclusive character of water would place it in the category of "common goods" whose availability can be influenced by the "mass effects", which leads us to consider a risk of "tragedy of commons".Socially: in addition to the social distortions that can arise in situations of usage conflicts around the resource, the jobs created in this sector are seasonal and low-skilled, which may negatively affect a real local development process in these regions.In our analyses, we used several theoretical and empirical methodological tools and approaches within a macroeconomic framework. We have mainly used cointegration techniques and error correction models adapted to the study of time series in addition to statistical analyses over the period between 1970 and 2014.
