In this paper, we have employed the Kourtellos et al. (2007) threshold model to examine the relationship between inflation and relative price variability in Hong Kong, Argentina, Germany, Japan, Mexico and Philippines. Empirical results from Hong Kong, Japan and Mexico show that inflation are endogenous variables, and the relationship between these two variables appears to be a V shape for Hong Kong and Japan. However, the relationship appears to be positive for Mexico. Empirical results fail to reject the hypothesis of exogenous inflation for Argentina, Germany and Philippines, and the relationship between these two variables appears to be a V shape for Philippines and Argentina. There is no significant relationship between these two variables for Germany.

In this thesis, I examine the conventional assumption of identifying investment-specific technology by the inverse of the relative price of investment. Linking prices to technology in this fashion implies that the relative price is orthogonal to any other form of economic disturbance. However, recent research has found that both neutral technology and the relative price of investment are cointegrated in the postwar US. In the chapters that follow, I explore the impact of this identification by either linking the relative price of investment to total factor productivity, or by allowing this relative price to vary depending on investment demand. In all three chapters, I find that loosening this restriction has a sizable effect on the outcome of my research as it compares to the current literature. / Thesis / Doctor of Philosophy (PhD)

This paper investigates what factors affect the destination choice for Jordanian to 8 countries (Oman, Saudi Arabia, Syria, Tunisia, Yemen, Egypt, Lebanon and Bahrain) using panel data analysis. Number of outbound tourists is represented as dependent variable, which is regressed over five explanatory variables using fixed effect model. The finding of this paper is that tourists from Jordan have weak demand for outbound tourism; Jordanian decision of traveling abroad is determined by the cost of traveling to different places and choosing the cheapest alternative.

This thesis analyses the extent to which a boom in a particular export commodity sector (i.e., oil) affects relative price of non-tradable goods against tradable goods, the real exchange rate and competitiveness in the rest of the economy: This problem has been analysed in the early stage by (Corden and Neary 1982) with the so-called ‘Dutch-disease’. As a result, booming sector (oil Sector) the country’s currency appreciates, thereby reducing the competitiveness of the country’s traditional export sector in international market. This thesis examines whether Dutch Disease is present in Iraq in the light of having not study about Dutch Disease phenomena. It evaluates the impact of growing oil revenues on non-oil sectors of the Iraqi economy. It produces some empirical evidence for the explanation non-tradable goods and contraction of tradable goods sector due to booming oil sector and appreciation real exchange rate and made tradable goods sector become uncompetitive for export. The main findings form this thesis that the Iraqi economy was subject to have the Dutch disease phenomena during the boom. Some of the indications of the disease, remarkably the increase of relative prices, the real exchange rate appreciation, contraction tradable goods sector and expansion of nontraded goods output were applicable. The study uses annual time series data sourced from home and international agencies from 1970 to 2013. Due to problem with endogeneity, the data are analysed through the use of two stages least square. Finally, the thesis discusses briefly some policy measures that will help avoid the issue of appreciation real exchange rate and changing the structure of economy out of tradable goods to non-tradable goods sector.

This thesis consists of three self-contained essays dealing with different aspects of macroeconomics and political Economy. The Relative Price of Investment Goods and Sectoral Contract Dependence I develop a quantitative model to explain the relationship between TFPs at the aggregate and sector levels and contracting institutions across countries. The incomplete contract enforcement induces distortions in the production process which come from the “hold up” problem between a final goods firm and its suppliers. Because investment goods sector is more contract dependent, its productivity suffers more from the distortion. In turn, countries endowed with weaker contract enforcement institutions face higher relative prices of investment goods. A Ricardian Model of the Labor Market with Directed Search I analyze how search friction affects the allocation in a Ricardian model of the labor market. The equilibrium shows that the matching pattern is partially mixed: Some tasks are only performed by skilled workers; some are only performed by unskilled workers; the remaining tasks are performed by both skilled and unskilled workers. The mixed matching pattern implies a mismatch in equilibrium. It turns out that the reason for the mismatch has its roots in search friction. In addition, I show labor market institutions have interesting implications for the unemployment rate and mismatch. A Dynamic Analysis of the Free-rider Problem I argue that special interest groups overcome their free-rider problem thanks to distorted government policy. As policy confers monopoly privileges on a group, it can also preserve and promote group’s organization. The key to sustaining the organization of the group is a dynamic incentive: when distorted policy generates rents for a group, each member of the group wish to make contributions not just to raise their rents today; they want to sustain their cooperation so that they will be able to influence policy in the future.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / A avaliaÃÃo dos efeitos da inflaÃÃo na Variabilidade de PreÃos Relativos (VPR) à uma fonte de subsÃdios aos formuladores de polÃtica econÃmica no que se refere à tomada de aÃÃes preventivas contra possÃveis pressÃes inflacionÃrias, minimizando os custos em termos de variaÃÃo do produto e do emprego. Dessa forma, este trabalho visa verificar empiricamente o impacto da adoÃÃo de metas para inflaÃÃo (MI) na relaÃÃo entre inflaÃÃo e VPR na economia brasileira, durante o perÃodo de 1995 a 2012. Seguindo evidÃncias da literatura, foram estimados modelos onde tal relaÃÃo assume a forma linear com quebras estruturais e a forma quadrÃtica a fim de testar qual deles melhor se ajusta aos dados brasileiros. Baseado em Bai e Perron (1998, 2003), os modelos de regressÃo foram estimados tratando as datas de quebras como variÃveis desconhecidas, obtidas endogenamente, em julho de 1998 e novembro de 2002. Para o perÃodo analisado os resultados nÃo corroboram as evidÃncias do formato de U da relaÃÃo entre inflaÃÃo e VPR, sendo que o efeito marginal da inflaÃÃo sobre a VPR à positivo, embora sua magnitude seja reduzida apÃs a adoÃÃo das metas e ainda mais apÃs o ganho de credibilidade referente ao cumprimento das mesmas. Adicionalmente observou-se que a relaÃÃo entre a inflaÃÃo esperada e a VPR se enfraqueceu apÃs a adoÃÃo das metas, enquanto a inflaÃÃo nÃo esperada somente se tornou significativa a partir da adoÃÃo desta polÃtica. / The assessment of the inflation effects on the Relative Price Variability (RPV) is a source of subsidies for economic policymakers when it comes to taking preventive measures against possible inflationary pressures, thus minimizing the costs in terms of product variation and employment. Once exposed that, this work aims to empirically investigate the effects of inflation targeting (IT) adoption on the relationship between inflation and RPV in the Brazilian economy from 1995 to 2012. Based on the literature, two models were estimated in order to test which one best fits in the Brazilian data. In the first one, the relationship takes the linear shape, while in the other it is U-shaped. Following Bai and Perron (1998, 2003), the regression models were estimated treating the dates of breaks as unknown variable, which were endogenously obtained in July of 1998 and November of 2002. In the period analyzed, the results do not corroborate the evidence of the U-shaped relation between inflation and RPV, once the marginal effect of inflation on the RPV is positive, although its magnitude is reduced after the adopting of IT and even more after the adoption of measures that gave credibility to comply with them. Additionally it was observed that the expected inflation had its effect reduced on RPV after the IT adoption, while the unexpected inflation only becomes significant after the adoption of this policy.

Differences in price levels as well as inflation rates among countries have been subject of discussion for a long time. More than the actual levels, however, the question of determinants of price levels in time and a possible convergence is key for the new member states with respect to the Maastricht criteria. The dynamics of price levels is crucial, and many suggestions have been put forward to explain the observed trends and changes. This thesis focuses on the determinants of relative price level, and hence real exchange rate, developments in the new member states of the EU and employs a regression analysis to examine their change in time. As most of the countries in focus are transition economies, structural variables are also included among the independent variables. We find that the Balassa- Samuelson effect is key to explaining real exchange rate developments as the effect of productivity differential has been significant over the whole period examined. However, in the recent years, marked by the onset of the crisis, other factors, such as the structure of trade and Euro area membership, have become more prominent.

The relations between monetary policies, asset prices, and economic growth are important and fundamental questions in macroeconomics. To address these issues, several empirical works have been conducted to investigate these relations. However, few of them have documented whether these relations differ across regimes. In this context, the general motivation of this thesis is to use dependent regime models to examine these relations for the Canadian case. Chapter one empirically analyzes the interest rate behaviour of the Canadian monetary authorities by taking into account the asymmetry in the loss function. We employ a switching regime framework using two estimation strategies: First, we follow Caner and Hansen (2004) Threshold approach. Under this procedure we estimate the threshold values, using the Taylor empirical rules. Second, we estimate the asymmetric policy reaction function following Favero and Rovelli’s (2003) approach. The results reveal that the monetary authorities showed asymmetric preferences and that its reaction function can be better modeled with a nonlinear model. The main contribution of this chapter is to successfully interpret the parameters associated with the Bank of Canada preferences, something that Rodriguez (2008) could not do. Chapter two tries to estimate the interest rate behaviour of the Canadian monetary authorities by expanding the arguments of the loss function for fluctuations in asset prices. Using the same methodology as in the first chapter, our findings suggest that the augmented nonlinear reaction function is a good fit for the data and gives new relevant insights into the influence of asset prices on Canadian monetary policy. These findings about the role of asset prices in the reaction function of the Bank of Canada provide relevant insights regarding the opportunities and limitations of incorporating financial indicators in monetary policy decision making. They also provide financial market participants, such as analysts, bankers and traders, with a better understanding of the impact of stock market index prices on Bank of Canada policy. Stock market stabilization plays a larger role in the interest rate decisions of the Bank of Canada than it is willing to admit. Chapter three provides new evidence on the relation between inflation, relative price variability and economic growth to a panel of Canadian provinces over the period 1981-2008. We use the Bick and Nautz (2008) modified version of Hansen’s (1999) Panel Threshold Model. The evidence strongly supports the view that the relationship between inflation and economic growth is nonlinear. Further investigation suggests that relative price variability is one of the important channels through which inflation affects economic performance in Canadian provinces. When taking into account the cross-section dependence, we find that the critical threshold value slightly changes. It is desirable to keep the inflation rate in a moderate inflation regime because it may be helpful for the achievement of sustainable economic growth. The results seem to indicate that inflation that is too high or too low may have detrimental effects on economic growth.
