Firms' operational restructuring involves information relevant to strategic choices as well as future demand and cost conditions. This study examines the relationship between peer firms' restructuring and a company's responsiveness to its growth opportunities. Peer firm restructuring can increase uncertainty with respect to a company's payoffs regarding its investment projects, leading to decreased responsiveness to growth opportunities. Using a large sample of public companies during 2006–2020, I find that peer firms' restructuring is negatively associated with the responsiveness of capital expenditures (Capex) to growth opportunities. The results suggest that peer firms' restructuring activities provide information about a company's investment projects above and beyond industry shocks reflected in changes in industry sales. Furthermore, these associations are moderated by industry competition. The negative effects of peer firms' restructuring on Capex sensitivity are the strongest in high-competition industries.

This study deals with foreign direct investments and their impacts on regional labour market and on domestic firms through spillover effects. The main goal was to find out if the foreign presence has positive influences on the host regional economy. This study has two important parts - quantitative and qualitative researches. The result of quantitative research based on multiple regression comes with no relevant empirical evidence of spillover effects. The qualitative research as a case study of TRCZ allows a trying to solve possible FDI-impacts on regional economy of Lovosice region. Keywords: foreign direct investment, multinational enterprises, impact of FDI, host economy, spillover effects

本文利用介入模式分析中共改革開放所造成的經濟結構之轉變，並建構包含軍事、非軍事政府、及私人等三部門的生產函數，來探討其與經濟成長之間的關聯性。實證結果顯示，改革開放使得中國大陸由閉關自守的內向型經濟轉為高貿易依存度的外向型經濟，經濟體制由計劃經濟邁向多元經濟成分共同發展的市場經濟，整體投資環境獲得改善，而軍事支出雖持續增加，但相對於高經濟成長，其軍事支出規模卻是下降的。此外，中共的經濟成長主要來自於積累率的提昇、公部門支出的正面影響和外溢效果、及國際經濟關係的開放，而技術變遷和勞動投入之成長的影響並不顯著。 / This article proposes intervention model to analyze the structural change of China’s transitional economy. We identify the relationship between economic growth and structural change by using the production functions from military, nonmilitary, and private sectors. The results indicate a more market-oriented economy and changing relationship between private and public ownership will continue to drive China toward modernization. In contrast to high economic growth, although military expenditure is still increasing but its relative scale is declining. The main sources of China’s economic growth are from the increase of accumulation rate, the positive and spillover effects of public expenditures, and the liberalization of international economic relations. Especially, much of China’s growth has come from producing goods for foreign trade. While on the other hand, the impacts of technological change and increased labor inputs are not significant in this study.

This doctoral dissertation proposes methodologies which, from a linear or a non-linear approach, accommodate to the information flow and can deal with a large amount of data. The empirical application of the proposed methodologies contributes to answer some of the questions that have emerged or that it has potentiated after the 2008 global crisis. Thus, essential aspects of the macroeconomic analysis are studied, like the identification and forecast of business cycles turning points, the business cycles interactions between countries or the development of tools able to forecast the evolution of key economic indicators based on new data sources, like those which emerge from search engines.

Sweden is a country that has made significant achievements regarding sustainable development through its implementation of the Sustainable Development Goals (SDGs). Regardless of its efforts and leading position in global sustainability work, scholars have pointed out how other countries are negatively affected by its actions. Previous research also emphasized how nega- tive global spillover effects lead to adverse events affecting the world environmentally, socially, and economically. By conducting a qualitative content analysis through the lens of the theoret- ical framework, The Spillover Index, this study aims to shed light on the overlooked negative spillover effects stemming from Sweden's implementation of the SDGs. This paper recognizes the actions and acknowledgments made by Sweden on its negative spillover effects, along with unintended consequences and contradictions. The result of this thesis emphasizes the urgency for a more holistic understanding of sustainability and the SDGs, calling for countries to con- sider when implementing its sustainability work, not only national achievements, and gains but also the extensive impact of its actions in a global context.

The recent period of intensified electricity price volatility has challenged both private households and businesses, resulting in companies transitioning their strategies to address the uncertainties that follow. No previous study has analysed how electricity price volatility affects Swedish industries’ returns and electricity usage. Therefore, this essay aims to fill this knowledge gap and capture the impact of electricity price volatility on two different industries, one more electricity-intensive industry and one less electricity-intensive industry. By applying a DCC-GARCH model, the study examines the impact on the returns and electricity usage of two industries to analyse if electricity price volatility has affected businesses in terms of returns and electricity consumption.  The first DCC model was run on weekly electricity spot price data from Nord Pool and data constructed through a proxy of each industry’s average return. The results show that there is almost zero conditional correlation over time, ranging from 0.03 to 0.045, between the electricity price and each industry’s returns. There are no short-run spillover effects from electricity price volatility on the on the industries’ average returns. On the other hand, there is a long term spillover effect from electricity prices to the more electricity-intensive industry and no long term spillover for the less electricity-intensive industry.  The second DCC-GARCH modell is applied on monthly electricity spot prices from Nord Pool and data of monthly electricity usage of each industry. The industries are sorted by Swedish Standard Industrial Classification (SNI). SNI 17 stands for manufacture of paper and paper products and SNI 24 stands for manufacture of basic metals. The results from this part indicates that the dynamic conditional correlation between electricity price and the electricity usage in the paper industry is close to zero which differ from the basic metal industry which is positive. Beyond the dynamic conditional correlation, we find a short-term spillover effect from electricity price volatility to electricity usage in the basic metal industry, which is absent in the paper industry. On the other hand, there is a long-term spillover effect from electricity price volatility to electricity usage in the paper industry, which is absent for the electricity usage in basic metal industry.  Overall, our study shows that the businesses in the return proxy have preformed relatively well despite an uncertain period of volatile electricity prices. Simultaneously we find that the results for the industries electricity usage differ between the chosen industries.

Cette thèse contribue aux travaux récents sur les effets de la politique budgétaire à court terme sur l'économie. Plus précisément, sont étudiés dans cette thèse trois principaux aspects de la politique budgétaire à court terme. Premièrement, un des messages principaux consiste à dire que l'impact de la politique budgétaire sur l'économie dépend fortement de l'instrument fiscal utilisé. Augmenter les transferts aux ménages, augmenter l'investissement public ou diminuer les cotisations patronales sur les salaires produisent des effets fort différents sur les variables macroéconomiques clefs et notamment sur le niveau d'activité. Deuxièmement, au delà des effets sur l'activité économique, une large partie de cette thèse analyse l'impact de chocs budgétaires sur le marché du travail. Un des principaux résultats est qu'il paraît délicat de traduire des multiplicateurs sur l'activité en multiplicateurs sur le chômage, notamment à cause de la réponse de l'offre de travail.Troisièmement, nous savons que de multiples facteurs influencent la taille du multiplicateur budgétaire. Deux de ces éléments sont abordés dans cette thèse : la position de l'économie sur le cycle économique et la réponse de la politique monétaire. Les deux premiers chapitres de la thèse analysent ces différents aspects dans un cadre d'économie fermée. Les deux derniers chapitres traitent de la politique budgétaire en union monétaire en analysant les effets de débordement entre États membres ainsi que les capacités stabilisatrices de mécanismes de transferts budgétaires entre États membres afin d'amortir les chocs conjoncturels. / This thesis aims at contributing to the recent studies which investigate the short-run effects of fiscal policy on economic activity. More precisely, three main aspects of fiscal policy in the short run are analyzed. First, one major message is that the impact of fiscal policy on the economy depends strongly on the fiscal instrument used by the government. Rising transfers to households, increasing public investment or cutting social protection tax trigger very different effects on key macroeconomic variables and especially on output. Second, one large part of this thesis is dedicated to the analysis of the effects of fiscal policy shocks on the labor market. One main result is that we cannot determine unemployment fiscal multipliers according to the value of the output fiscal multiplier, especially because of the response of the labor force participation to fiscal policy shocks. Third, this is well-known that many elements influence the size of the output fiscal multiplier. Two of these elements are considered throughout this thesis: the position of the economy over the business cycle and the behavior of the monetary policy. The two first chapters of this thesis analyze these different aspects in some closed economy models. The two last chapters extend this study at the case of a monetary union by investigating the spillover effects of fiscal policy between member states but also the stabilizing properties of fiscal transfer mechanisms between member states in order to soften cyclical shocks.

This dissertation collects three essays which deal with financial development in emerging markets. Owing to the appliance of different econometric methods on several data sets, insights in the behavior of and the impacts from financial markets are generated. Usually, the financial markets in emerging countries are characterized by the presence of credit constraints. In the first chapter it is shown that the financial development in 19th century Germany generally affected the economy in a positive way. Additionally, when different economic sectors are under investigation, it is revealed that the reaction due to financial development is not homogeneously across the sectors. A structural vector autoregression (VAR) framework is applied to a new annual data set from 1870 to 1912 that was initially compiled by Walther Hoffmann (1965). With respect to the literature, the most important difference of this analysis is the focus on different sectors in the economy and the interpretation of the results in the context of a two-sector growth model. It is revealed that all sectors were affected significantly by shocks from the banking system. Interestingly, this link is the strongest in sectors with small or non-tradable-goods-producing firms, such as construction, services, transportation and agriculture. In this regard, the growth patterns in 19th century Germany are reminiscent to those in today's emerging markets. The second chapter deals with the integration of the stock markets of mainland China with those of the United States and Hong Kong. Market integration and the resulting welfare gains as risk sharing, increasing investment and growth benefits has become a central topic in international finance research. This chapter investigates stock market integration after stock market liberalization which is assessed by spillover effects from Hong Kong and the United States to Chinese stock market indices. Dividing the sample in pre- and post-liberalization phases, causality in variance procedure is applied using four mainland China stock market indices, two indices of the stock exchange in Hong Kong and the Dow Jones Industrials index in the main part. Evidence of global and regional integration is found, but no evidence for increasing integration after the partial opening of the Chinese stock markets, neither with Hong Kong nor with the United States. Based on the idea presented in the first chapter, the third chapter examines one of today's emerging markets. As China is experiencing remarkable economic growth in the recent decades, it is analyzed if and to what extent the ongoing deregulations in the financial system contribute to this development. Structural VARs for gross domestic product as well as for sectoral output data in conjunction with two different bank lending variables are applied. It is indicated that China is positive affected by financial development and that all sectors benefit from domestic bank lending enlargements but to different degrees. Especially in the sectors where mainly state-owned enterprises are represented - such as construction, trade and transportation - shocks in bank lending have a strong positive influence while sectors where private enterprises are prevalent, seem to be more credit constrained.
