Numerous studies have been undertaken on corporate and international diversification. While most early research indicates the existence of a diversification discount, later research reports mixed results (both premiums and discounts). Recent research has even found a U-shaped, an inverted U-shaped, or an S-shaped relationship between international diversification and performance. This paper suggests a major reason for these mixed results is that the success of international diversification is dependent on specific industry and/or firm characteristics. Therefore, by looking at all firms and industries in aggregate, past diversification studies have been undertaken at too aggregate a level to understand how firm and industry specific issues affect international diversification. This study hypothesizes that the success of international diversification is dependent upon industry and firm specific advantages such as tacit knowledge, information technology capability, marketing capability, and international experience. Industries/firms that possess a significant competitive advantage in one or more of these areas will likely have an international diversification premium, while those that do not will likely have an international diversification discount. The ability of firms to generate a competitive advantage in these areas varies significantly across industries. Therefore, firms in certain industries are likely to have an international diversification premium, while others will likely have an international diversification discount. The findings of this study do indicate that in the 30 industry sectors tested, 18 have an international diversification premium while 12 have an international diversification discount. This suggests that international diversification premiums/discounts by industry to exist. The firm specific advantages of tacit knowledge, information technology capability, and marketing capability were found to be positively correlated with firm performance for international firms, while the results of international experience with firm performance were not significant. / Business Administration/International Business Administration

This study concerns retail brands in the food retail industry and focuses on premium products. The research is investigating how ICA can best use premium products to increase their profitability. The study is thus based on their brand ICA Selection and investigates three sub purposes concerning the customers’ perception of the products, their purchase behavior and their willingness to pay a price premium.   To investigate, theory concerning brand resources was utilized, involving both brand equity and brand management. To measure brand equity, the authors adapted a customer mind set and utilized Aaker’s framework and the specific industry developments made by Anselmsson, Johansson and Persson. Accordingly, this theory is based on five brand equity attributes: perceived quality, brand associations, loyalty, awareness and uniqueness. These attributes were thereafter developed to explain food premium products. The brand management theory used was Kapferer’s brand management strategies, in order to assess ICA’s strategic advantages and disadvantages.   The research was quantitative and the authors utilized a visit self completion questionnaire, in order to describe and investigate the purpose. The questionnaire was handed out according to a systematic sampling method, to customers at the 4 different concept ICA stores in Umeå.   Based on the findings, the authors concluded that in order to increase the profitability of ICAs food premium products, the following strategies should be considered. First, the customer awareness of ICA Selection must be increased and the customers must be educated about the benefits of the product. Moreover, the premium brand should aim to provide value for money, high intrinsic product quality (i.e. taste, ingredients etc) and an improved store image. These factors will help defend the price premium.  Furthermore, to attract buyers, the brand has to have a high enough brand status and a sufficiently attractive and functional packaging. This research has therefore concluded how to efficiently allocate the resources and obtain an increased customer satisfaction. This may in turn increase the profitability of ICA Selection. However, it is of course important to also take into account the external environment, such as the recession and competition, when deciding on the brand strategy.

Intention: The purpose of this thesis is to see if an active investment decision in the Swedish Premium Pension System would result in a higher return than a non-active investment decision. A non-active investment decision is equivalent to leaving the money in AP7 Premium Savings Fund. Method: This thesis is a statistical analysis and has a descriptive character in which the calculations are based on secondary data, thus the thesis has a quantitative character. Furthermore three active portfolios in different risk categories have been chosen. These portfolios are compared with the AP7 Premium Savings Fund’s returns. The thesis is deductive because it is using existing financial theories to do empirical examinations. Conclusion: Generally, higher risk is equal to higher returns. This thesis shows that an active investment of the premium pension should be done in portfolios with higher risk. Therefore the selected low-risk portfolio has lower returns than AP7 Premium Savings Fund. Further Research: The authors would find it interesting to redo this study in the future with the new AP7 Såfa as a benchmark. / Syfte: Studien avser att se om ett aktivt sparande och förvaltande av premiepensionen leder till en högre avkastning i jämförelse mot att låta pengarna ligga kvar i AP7 Premiesparfond Metod: Studien är en statistik analys och har en deskriptiv karaktär där sekundärdata ligger till grund för beräkningarna. Studien kan således ses som en kvantitativ studie. Vidare har tre stycken aktiva portföljval i tre olika riskkategorier tagits fram för att jämföras med AP7 Premiesparfonds avkastning. Studien är deduktiv då den empiriska prövningen sker med hjälp av redan befintliga finansiella teorier. Slutsats: Generellt sett ger högre risk en högre avkastning. Studien visar att om premiepensionen ska förvaltas aktivt bör detta göras i portföljer med högre risk. Då den valda lågriskportföljen gav lägre avkastning än AP7 Premiesparfond. Vidare forskning: Författarna anser det intressant att jämföra om AP7 Såfa skulle gynna icke aktiva sparare i högre grad än den gamla AP7 premiesparfonden. AP7 Såfa är en generationsfond där risken anpassas efter spararens ålder. Studien bör därför omprövas då det finns tioårig historik om AP7 Såfa.

This research aims to identify the determinants of the ex-ante risk premium required by Italian private equity funds (PEFs) when valuing privately-held target companies. In theory, perceived risk is a key driver of expected returns and anticipated value, but: "Although PE (private equity) has experienced rapid growth, the risk and return profile of this asset class is not well understood." (Jegadeesh et al., 2009). Some papers have attempted to assess the ex post returns pioneered by Lerner & Gompers (1997). Yet such studies reveal both contradictory conclusions and hitherto inexplicable phenomena: what some authors call the 'private equity premium puzzle' (Moskowitz & Jorgensen, 2000). Such contradictory conclusions include a wide spread of abnormal realized returns ranging from -6% (Phalippou & Gottschalg, 2009) to +32% (Cochrane, 2005). In this research, the perceived risk and expected return drivers refer not to the ex-post realized return that PEF investors actually achieve, but to the required return the PEF hopes to gain from the target investment. At this stage, two important indicators adopted in PEF parlance have to be differentiated: (i) the Expected IRR (E.IRR) and (ii) the Threshold IRR (T.IRR). The first is the IRR as an output of a business plan, and the second assesses the return expected by PEFs according to the risk perceived in the business plan. Put simply, these are respectively, the anticipated return and the (risk-adjusted) required return. The study of the T.IRR is one of the main contributions of this thesis since it has never been studied before by academia as an indicator of the ex-ante perceived risk of a PEF target company. This is partly due to two important reasons. First, most previous papers examine ex-post performance, and only a few (e.g. Manigart et al., 2002), try to assess return expectations and risk perceptions using an ex-ante perspective. Second, most of the prior studies are quantitative and try to measure statistical effects captured by the ex-post IRR. By studying 26 deals (in 13 Italian PEFs) in detail (qualitatively and quantitatively), this research project has been able to observe how PEFs assess risk and estimate the T.IRR. The research project reveals that PEFs apply neither rational-based models nor explicit formulae to assess risk exante. By observing a set of phenomena unique to the PEF sector (fees effect, investment speed effect, persistence effect, money-chasing deal phenomenon, illiquidity effect, etc) whose existence has been suggested by many recent papers, this thesis has been able to propose an adjusted version of the three-factor model of Fama and French (1993, 1995) to assess risk. The application of a quasi-rational-based asset pricing model to guide PEFs assessments is also an important contribution of this thesis. In fact, Franzoni, Nowak and Phalippou (2010), claim to be the first to calculate the PEFs' cost of capital by applying asset pricing models. However, their approaches are not only based on the observations of realized returns, but also consider only one additional factor to the standard Fama & French three-factor model (1993), the liquidity factor. In contrast, the results and the model proposed by this thesis are based on qualitative and quantitative ex-ante information and include not only the classical factors of that model, but also some other factors intended to explain some of the phenomena listed above which might also drive the risk premium in private equity funds. Based, therefore, on explaining the behavior of PEFs, the research develops a framework that can be applied by Italian PEFs and perhaps other PEFs in a more rational manner than their past behavior suggests.

<p>My dissertation, consisting of three related essays, aims to understand the role of macroeconomic risks in the stock and bond markets. In the first chapter, I build a financial intermediary sector with a leverage constraint a la Gertler and Kiyotaki (2010) into an endowment economy with an independently and identically distributed consumption growth process and recursive preferences. I use a global method to solve the model, and show that accounting for occasionally binding constraint is important for quantifying the asset pricing implications. Quantitatively, the model generates a procyclical and persistent variation of price-dividend ratio, and a high and countercyclical equity premium. As a distinct prediction from the model, in the credit crunch, high TED spread, due to a liquidity premium, coincides with low stock price and high stock market volatility, a pattern I confirm in the data.</p><p>In the second chapter, which is coauthored with Hengjie Ai and Mariano Croce, we model investment options as intangible capital in a production economy in which younger vintages of assets in place have lower exposure to aggregate productivity risk. In equilibrium, physical capital requires a substantially higher expected return than intangible capital. Quantitatively, our model rationalizes a significant share of the observed difference in the average return of book-to-market-sorted portfolios (value premium). Our economy also produces (1) a high premium of the aggregate stock market over the risk-free interest rate, (2) a low and smooth risk-free interest rate, and (3) key features of the consumption and investment dynamics in the U.S. data.</p><p>In the third chapter, I study the joint determinants of stock and bond returns in Bansal and Yaron (2004) long-run risks model framework with regime shifts in consumption and inflation dynamics -- in particular, the means, volatilities, and the correlation structure between consumption growth and inflation are regime-dependent. This general equilibrium framework can (1) generate time-varying and switching signs of stock and bond correlations, as well as switching signs of bond risk premium; (2) quantitatively reproduce various other salient empirical features in stock and bond markets, including time-varying equity and bond return premia, regime shifts in real and nominal yield curve, the violation of expectations hypothesis of bond returns. The model shows that term structure of interest rates and stock-bond correlation are intimately related to business cycles, while long-run risks play a more important role to account for high equity premium than business cycle risks.</p> / Dissertation

<p>This dissertation explores issues regarding the short-lived temporal variation of the equity risk premium. In the past decade, the equity risk premium puzzle is resolved by many competing consumption-based asset pricing models. However, before \cite{btz:vrp:rfs}, the return predictability as an outcome of such models has limited empirical support in the short-run. Nowadays, there has been a consensus of the literature that the short-run equity return's predictability is intimately linked with the variance risk premium---the difference between options-implied and actual realized variation measures.</p><p>In this work, I continue to argue the importance of the short-lived components in the equity risk premium. Specifically, I first provide simulation evidence of the strong return predictability based on the variance risk premium in the U.S. aggregate market, and document new empirical findings in the international setting. Then I attempt to use a structural macro-finance model to guide through the predictability estimation with much more efficiency gain. Finally I decompose the equity risk premium into two short-lived parts --- tail risk and diffusive risk --- and propose a semi-parametric estimation method for each part. The results are arranged in the following order.</p><p>Chapter 1 of the dissertation is co-authored with Tim Bollerslev, James Marrone and Hao Zhou. In this chapter, we demonstrate that statistical finite sample biases cannot ``explain'' this apparent predictability in U.S. market based on variance risk premium. Further corroborating the existing evidence of the U.S., we show that country specific regressions for France, Germany, Japan, Switzerland, the Netherlands, Belgium and the U.K. result in quite similar patterns. Defining a ``global'' variance risk premium, we uncover even stronger predictability and almost identical cross-country patterns through the use of panel regressions. </p><p>Chapter 2 of the dissertation is co-authored with Tim Bollerslev and Hao Zhou. In this chapter, we examine the joint predictability of return and cash flow within a present value framework, by imposing the implications from a long-run risk model that allow for both time-varying volatility and volatility uncertainty. We provide new evidences that the expected return variation and the variance risk premium positively forecast both short-horizon returns \textit{and} dividend growth rates. We also confirm that dividend yield positively forecasts long-horizon returns, but that it does not help in forecasting dividend growth rates. Our equilibrium-based ``structural'' factor GARCH model permits much more accurate inference than %the reduced form VAR and</p><p>univariate regression procedures traditionally employed in the literature. The model also allows for the direct estimation of the underlying economic mechanisms, including a new volatility leverage effect, the persistence of the latent long-run growth component and the two latent volatility factors, as well as the contemporaneous impacts of the underlying ``structural'' shocks.</p><p>In Chapter 3 of the dissertation, I develop a new semi-parametric estimation method based on an extended ICAPM dynamic model incorporating jump tails. The model allows for time-varying, asymmetric jump size distributions and a self-exciting jump intensity process while avoiding commonly used but restrictive affine assumptions on the relationship between jump intensity and volatility. The estimated model implies that the average annual jump risk premium is 6.75\%. The model-implied jump risk premium also has strong explanatory power for short-to-medium run aggregate market returns. Empirically, I present new estimates of the model based equity risk premia of so-called "Small-Big", "Value-Growth" and "Winners-Losers" portfolios. Further, I find that they are all time-varying and all crashed in the 2008 financial crisis. Additionally, both the jump and volatility components of equity risk premia are especially important for the "Winners-Losers" portfolio.</p> / Dissertation

Understanding the Equity Risk Premium (ERP) and the factors affecting it is cardinal to financial economics, particularly to equity research analysts, domestic and international institutional investors and financial economist. Since the seminal work of Mehra and Prescott (1985) there has been an exponential rise in the research explaining the reasons for ERP puzzle. This review, systematically, investigates the literature related to ERP in four key dimensions. The first dimension is regarding the issues related to different techniques of estimating the ERP. The second dimension is regarding the studies that explain the reasons of existence of the ERP puzzle by making modifications to the preference structures. The third is regarding the macroeconomic variables that help in predicting ERP and the fourth deals with studies that are conducted in the international context. In addition to this, this review meticulously captures some important limitations of the existing literature regarding the estimation of ERP and identifies the domestic and international determinants of ERP, in particular the UK ERP and proposes novel future directions of research. These future research directions have two important implications for my PhD. The first is the academic contribution that predominantly comes from methodological contribution of estimating the ERP. The second is the practical contribution that comes mainly from identifying the unique set of variables (UK domestic and international), which are of prime importance to the domestic and foreign institutional investors because of the financial crisis of 2008-2009 and which should affect the UK ERP.

Announcements of acquisitions of publicly traded companies are usually accompanied by their share price booming by tens of percent. The underlying reason is that the acquirer of the company gains a controlling stake, due to which he can help the company pivot in the desired direction or benefit from synergy effects. A minority investor, by definition, is not capable of doing this, thus he is willing to pay a lower price for the shares than the acquirer of the controlling stake. The thesis analyzes whether a minority shareholder can profit from the acquisition premium by purchasing shares of companies which he believes will be later acquired. The paper consists of two parts - theoretical and analytic. The theoretical part discusses the significance of the acquisition premium and its value, with regard to the type of investor and his motivations for the acquisition. The theoretical part yields into the analytic part, where acquisition waves are tested. It also includes an analysis of individual acquisitions and their underlying reasons, which are grouped into categories in order to find patterns of aquired companies.
