Yes / Using 2605 Chinese A-share listed companies in the mining, manufacturing, and energy production and supply sectors from 2009 to 2020, we examine the relationship between climate policy uncertainty (CPU) and firm-level total factor productivity (TFP). The main findings are as follows: First, CPU significantly reduces firm-level TFP, with a greater impact on low-productivity firms than on high-productivity firms; second, the negative effect of CPU on firm-level TFP is most pronounced for non-state-owned, labor-intensive, and capital-intensive companies; third, CPU hinders research and development investment and reduces the amount of free cash flow. These results indicate that CPU exerts negative impacts on firm-level TFP mainly via its effects on the capital status of the companies. Our findings remain valid after a series of robustness tests and controlling for endogeneity. The government should introduce forward-looking climate policies to reduce the negative impact of policy uncertainty. / This research was supported by the Natural Science Fund of Hunan Province (2022JJ40647) and Zhejiang Provincial Natural Science Foundation of China under Grant No: LZ20G010002.

This thesis examines whether the level of Swedish economic policy uncertainty (EPU) can predict excess returns on the Swedish stock market. We run out-of-sample forecasting using an EPU-based predictive model constructed with the official Swedish EPU index developed by Armelius et al. (2017). Forecasting errors for one-, two-, three-, six-, and twelve-month holding periods and four measures of central tendency are analysed and compared against a random walk benchmark. The findings suggest that EPU has limited forecasting ability for excess stock returns in Sweden, and the EPU-based model demonstrates superior forecasting accuracy only in two out of twenty instances, both for the one-month holding period. However, the forecast errors remain relatively large, casting doubt on the model's ability to outperform the market. Furthermore, the EPU-based model consistently underestimates excess returns, questioning its usefulness as a predictor. Notably, the random walk benchmark's forecast error improves with longer holding periods, raising doubts about the predictability of market movements in the long term.

In this study, we investigate the relationship between national and global uncertainty with house prices. Uncertainty is measured with the economic policy uncertainty index developed by Baker et al. (2016). The relationship is evaluated with eight SVAR-models that are Cholesky decomposed to restrict the contemporaneous relationship between variables, this is used to model the housing market. We create two models for each country, one that includes the local uncertainty and one that includes global uncertainty. The studied countries are two larger and two smaller economies in the EU, namely Sweden, Denmark, Germany, and France. We investigate the impulse response functions to establish the short-run dynamics and then compare them amongst each other. The results show that uncertainty has a negative effect on house prices and that global uncertainty hasa larger impact than local uncertainty, except for Sweden´s case. Germany is most resilient to the effect of uncertainty among the studied countries. This can be because of the size of the rental housing market in Germany. Interestingly we also find that in all cases except for Denmark our models don’t find a consistent relationship between short-term interest and housing prices in the short run, which can be an indication of a bubble. Further studies are required to investigate how different housing policies affect the volatility of the housing market that is created by uncertainty.

No / We compare actual and calibrated values for the foreign exchange risk premium based on the definition in [J. Int. Econ. 32 (1992) 305]. Calibrated values are found from within a dynamic stochastic general equilibrium model of a small open economy consisting of risk averse optimizing agents with unconventional preferences. We find that the equilibrium foreign exchange risk premium is a function of exogenous shocks in the model and is sensitive to assumed attitudes towards risk. Furthermore, various forms of policy uncertainty improve the capacity of the model to generate values closer to those found in the data.

Chapter 2 considers technology adoption under both technological and subsidy uncertainties. Uncertainty in subsidies for green technologies is considered as an example. Technological progress is exogenous and modeled as a jump process with a drift. The analytical solution is presented for cases when there is no subsidy uncertainty and when the subsidy changes once. The case when the subsidy follows a time invariant Markov process is analyzed numerically. The results show that improving the innovation process raises the investment thresholds. When technological jumps are small or rare, this improvement reduces the expected time before technology adoption. However, when technological jumps are large or abundant, this improvement may raise this expected time. Chapter 3 studies technology adoption in a duopoly where the unbiased technological change improves production efficiency. Technological progress is exogenous and modeled as a jump process with a drift. There is always a Markov perfect equilibrium in which the firm with more efficient technology never preempts its rival. Also, a class of equilibria may exist that lead to a smaller industry surplus. In these equilibria either of the firms may preempt its rival in a set of technology efficiency values. The first investment does not necessarily happen at the boundary of this set due to the discrete nature of the technology progress. The set shrinks and eventually disappears when the difference between firms’ efficiencies increases. Chapter 4 studies the behavior of two firms after a new investment opportunity arises. Firms either invest immediately or wait until market uncertainty is resolved. Two types of separating equilibrium are possible when sunk costs are private information. In the first type the firm with lower cost invests first. In the second type the firm with higher cost invests first leading to a smaller industry surplus. The results indicate that the second type is possible only for strictly negatively correlated sunk costs. Numerical analysis illustrates that when first mover advantage is large, the firm that delays the investment should be almost certain about its rival’s sunk cost. When market risk increases, the equilibria can exist when the firm is less certain. / text

Malgré les progrès de la coopération internationale, les enjeux politiques nationaux l’emportent souvent sur leurs pendants internationaux dans l’opinion publique. En gardant à l’esprit cette complexité qui entoure les relations internationales nous allons explorer, tout au long de cette thèse, différentes pistes liées à l’interdépendance entre pays et à la propagation internationale des politiques économiques.Tout d’abord, afin de mieux comprendre les enjeux internationaux des indications prospectives en cas de ZLB, nous développons, un modèle d’équilibre général à deux pays avec rigidités nominales des prix. Nous montrons qu’en cas de récession due à des anticipations pessimistes, une règle de Taylor augmentée et l’engagement à suivre cette règle, permettent de lisser les réactions des économies aux chocs.Ensuite, nous étudions l’effet de l’incertitude politique dans les pays avancés sur les flux de capitaux vers les pays émergents. Nous trouvons que cet impact sur les flux actions dépend largement de la source de l’incertitude (États-Unis ou Union Européenne). De plus, nous trouvons que la propagation des chocs varie en fonction du degré de stress financier mesuré par le VIX. Enfin, l’effet de l’incertitude politique européenne dépend aussi du risque souverain du pays émergent recevant les flux.Enfin, étant donné la dépendance de certains pays producteurs de matières premières envers l’investissement chinois, il nous paraît pertinent d’étudier quel serait l’impact d’un ralentissement de la Chine en particulier sur l’économie de ces pays. Nous trouvons que les pays d’Amérique Latine sont les plus fortement touchés, suivie par l’Asie (hors Chine). / Although international cooperation has been improved, national political issues are often outweighing international ones. Keeping in mind all this complexity which comes with international relations, we will explore several avenues of research on international linkages and economic policy spillovers.First, in order to better understand the international issue of forward guidance in case of ZLB, we develop a two-country general equilibrium model with price rigidities. We show that the augmented Taylor rule when the economy is at the zero bound, and the commitment to follow this rule, may help the economy to react in a smoother way to adverse productivity news shocks.Second, we examine the extent to which uncertainty with regard to macroeconomic policies in advanced countries spills over to emerging markets via gross portfolio bond and equity flows. We find that the impact of fluctuations in policy uncertainty on portfolio equity flows differs markedly depending on whether changes in policy uncertainty originate from the US or the EU. The size and direction of these spillover effects depends on the level of global risk, with increased European policy uncertainty only having a negative impact on bond inflows into EMEs when global risk is high. For equity inflows, the level of country-specific sovereign default risk also matters for nonlinearities.Finally, given the dependence of some commodity exporters to Chinese investment-led growth policies, we assess the potential impact of a Chinese hard-landing. According to our estimates, Latin American countries would be hardest hit, followed by Asia (ex. China); advanced economies would be less affected.

This study examines the dynamic relationship between changes in oil prices and the economic policy uncertainty index for a sample of both net oil-exporting and net oil-importing countries over the period 1997:01-2013:06. To achieve that, we extend the Diebold and Yilmaz (2009, 2012) dynamic spillover index using structural decomposition. The results reveal that economic policy uncertainty (oil price shocks) responds negatively to aggregate demand oil price shocks (economic policy uncertainty shocks). Furthermore, during the Great Recession of 2007-2009, total spillovers increase considerably, reaching unprecedented heights. Moreover, in net terms, economic policy uncertainty becomes the dominant transmitter of shocks between 1997 and 2009, while in the post-2009 period there is a significant role for supply-side and oil specific demand shocks, as net transmitters of spillover effects. These results are important for policy makers, as well as, investors interested in the oil market. (authors' abstract) / Series: Department of Economics Working Paper Series

This cumulative dissertation aims to complement existing literature with insights on two topics gaining strong importance in the Private Equity Industry: 1) cross-border investments and 2) co-investments with portfolio firm management in times of uncertainty. Results in paper on cross-border investments suggest that the physical presence of a local office of PE firms can actually make a difference for foreign investments. With a local office, operating performance of PE firms is higher after the buyouts. Local offices are especially beneficial for performance the higher the perceived foreignness between PE firm and portfolio firm is. In addition, PE firms increase deal flow after a local office opening, do less syndicates and have higher deal volumes. Respective results imply it is worth in future research to differentiate between pure cross-border deals and deals operated through a local office. The forth paper sheds light on the positive relationship between management buyouts (MBOs) and economic policy uncertainty. Analyses indicate that access to information is a relevant channel for higher propensity of MBOs in uncertain times.:1 Introduction 1.1 Trends in private equity industry 1.2 Overview of essays 2 The Cross-Border Buyout Next Door 2.1 Introduction 2.2 Theoretical background 2.3 Data 2.4 Operating performance results 2.5 Insights from semi-structured interviews 2.6 Conclusion 3 Opening a Local Office - PE Firms' Engine for International Expansion? 3.1 Introduction 3.2 Theoretical background 3.3 Sample and data 3.4 Determinants of office openings 3.5 Impact of local offices 3.6 Conclusion 3.A Appendices 4 Entrepreneurial Activity in Times of Uncertainty: The Case of Management Buyouts 4.1 Introduction 4.2 Literature review and hypotheses 4.3 Material and methods 4.4 Results and discussion 4.5 Conclusions 4.A Appendices References
