We derive and test a series of profitability factors for cross-section of expected returns on Japanese and Chinese equity markets. We find gross profitability predicts returns and significant both on Japanese and Chinese equity markets. We test these factors using Fama-MacBeth regression and find gross profitability and value portfolios perform better in Japan, size and gross profitability portfolios perform better in China. Then we create new three-factor model based on the result of 5*5 portfolios, which capture value and gross profitability premium in Japan, and, size and gross profitability premium in China. And the new models' GRS test performs better than Fama-French-three-factor model at the 5% significance level. / 博士(文化情報学) / Doctor of Culture and Information Science / 同志社大学 / Doshisha University

This study utilized hedonic pricing models and regression analysis to evaluate if, and to whatextent distance to certain logistics nodes impact the transactional value of warehouses andlogistics properties. The study is conducted in Sweden, using data collected from transactionsthat have been conducted in the three largest cities in Sweden between the years 2016 - 2022.The logistical nodes that are tested within the study are the biggest seaports, airports andhighways in the big city regions. Furthermore, the distances to the central business districts ineach respective city are included in the analysis as well. The distances are collected bymeasuring the shortest road travel routes using Google Maps. Aside from the aforementionedlocational attributes that were tested, physical variables and dummy variables were includedin the model to investigate their effect on the transaction value of the logistics properties.Furthermore, these were included to prove the robustness of the proposed models. The results from the study indicate that all the logistical nodes tested are significant for thevalue of the industrial properties. Proximity to seaport, central business district and highwayshave a negative gradient, indicating a higher value of the logistics properties if in proximityto these nodes. While the distance to the airport is significant for the value of the logisticsproperties, the proximity to the airport does not induce a higher transaction value. The studyconcluded that the distance to seaport had an effect of -0,50%, CBD -0,83%, Highway-0,62% and Airport 0,47% per kilometer of change. This study aims to contribute to theexpanding literature on the topic of optimal warehouse location and to inform propertyowners of what attributes to consider when constructing logistic properties. / Denna studie använder hedoniska prismodeller och regressionsanalys för att utvärdera om,och i vilken utsträckning avstånd till logistiknoderna hamn, flygplats och motorväg påverkartransaktionsvärdet för lager och logistikfastigheter. Studien genomfördes i Sverige med hjälpav data insamlad från transaktioner som har genomförts i de tre största städerna i Sverigemellan åren 2016 - 2022. Transaktionsdatan samlades in genom Datscha. Vidare utreds ävenhuruvida avstånd till central business districts har en inverkan på transaktionspriset.Avstånden mäts genom att mäta de kortaste transportsträckorna mellan fastighet och nod.Avstånden i fråga har samlats in med hjälp av Google Maps. Resultaten från studien tyder påatt alla logistiknoder som testats har betydelse för fastighetens värde. Närhet till hamn, CBDoch motorvägar har en negativ koefficient, vilket indikerar ett högre transaktionsvärde påfastigheten i de fall de är belägna i närheten dessa noder. Avståndet till flygplatsen har ocksåbetydelse för värdet på fastigheterna. Denna variabel har dock en positiv koefficient, vilketindikerar att närhet till denna logistiknod har en negativ inverkan på transaktionspriset.Slutsatsen från analysen indikerar att avståndet till hamn hade en effekt på -0,50%, CBD-0,83%, motorväg -0,62% och flygplats 0,47% per kilometer av förändring. Denna studiesyftar till att bidra till den växande litteraturen om ämnet optimal lagerlokalisering och attinformera fastighetsägare om vilka attribut som ska beaktas när de bygger logistikfastigheter.

This thesis investigates the complex dynamics of foreign exchange (FX) risk affecting Swedish multinational corporations and their financial performance, with a focus on the impact of company size and periods of economic crisis. Amidst global economic interdependencies, these entities encounter substantial FX risks, primarily due to the volatility of the Swedish Krona (SEK) against major currencies. Utilizing a comprehensive dataset spanning from 2004 to 2023, this study employs an empirical approach grounded in the International Capital Asset Pricing Model (ICAPM) and Purchasing Power Parity (PPP) to analyze the correlation between currency fluctuations and stock valuations. The analysis reveals that both company size and economic crises significantly modulate the effects of FX risks, with larger companies often better positioned to manage these risks through sophisticated hedging strategies. Smaller firms, conversely, show greater sensitivity to economic disruptions, particularly during crises which heighten the volatility of FX impacts. The findings indicate that FX risks significantly influence the financial outcomes of these firms, with both direct impacts on stock returns and indirect effects through operational strategies. The thesis underscores the importance of robust risk management strategies and the potential for policy adjustments to mitigate adverse effects from currency volatility. The insights derived from this research aims to contribute to a deeper understanding of the financial economics of foreign exchange, providing implications for investors and multinational corporations operating in global markets.

Die studie vergelyk die prestasie van 'n koop-en-hou-strategie met die van 'n tydsberekeningstrategie binne die raamwerk van die arbitrasie-prysbepalingsteorie (APT) op die nywerheidsindeks van die Johannesburgse Aandelebeurs (JA). Die periode van die studie is oor twee tydperke, naamlik Januarie 1970 tot September 1987 en Januarie 1989 tot Junie 1997. Die langtermyntendens van die nywerheidsindeks en APT-faktore is bepaal deur die beste nie-reglynige model vir elke tydreeks te vind. Reglynige meervoudige stapsgewyse regressie-ontleding is gebruik om die bewegings van die nywerheidsindeks rondom die langtermyntendens te voorspel. Die sloeringsreekse van die langtermyntendensresidutelling van die APT-faktore en die sloeringsreekse van die eerste-ordeverskiltelling van die langtermyntendensresidutelling is as moontlike voorspellers gebruik. Gegrond hierop is beslissingslyne ontwik:kel wat gebruik is vir die implementering van 'n tydsberekeningstrategie. Die resultate van die studie is die volgende: • Waar die sloeringsreekse van die langtermyntendensresidutelling van die APTfaktore as moontlike voorspellers gebruik is, is die risiko-aangepaste opbrengskoers van 'n tydsberekeningstrategie 6, 41 persent en 0, 71 persent b6 die van 'n koop-en-hou-strategie vir tydperk een en twee onderskeidelik. • Waar die sloeringsreekse van die eerste-ordeverskiltelling van die langtermyntendensresidutelling van die APT-faktore as moontlike voorspellers gebruik is, is die risiko-aangepaste opbrengskoers van 'n tydsberekeningstrategie 10,40 persent en 1,04 persent b6 die van 'n koop-enhou- strategie vir tydperk een en twee onderskeidelik. Die belangrikste gevolgtrekking van die studie is dat die APT en 'n tydsberekeningstrategie teoreties en prakties versoenbaar is op die JA. Aanbevelings vir toekomstige navorsing is die volgende: ( 1) sistematiese risikofaktore, anders as makro-ekonomiese faktore, behoort identifiseer te word wat die voorspellingswaarde van die faktore in die tweede tydperk van die studie kan verhoog; (2) elke stap van die model wat ontwikkel is, behoort op elke indeks van die JA toegepas te word om die risiko-aangepaste opbrengskoers van 'n tydsberekeningstrategie toegepas op elkeen van die indekse met die van 'n koop-en-hou-strategie te vergelyk; en (3) die invloed van transaksiekoste en dividende op die potensiele voordele van tydsberekening moet bepaal word. / The study compares the performance of a buy-and-hold strategy with that of a markettiming strategy in the framework of the arbitrage pricing theory (APT) applied to the industrial index of the Johannesburg Stock Exchange (JSE). The study period is divided into two parts, namely January 1970 to September 1987 and January 1989 to June 1997. The long-term trend of the industrial index and every APT factor is determined by finding the best nonlinear model for each time series. Linear multiple stepwise regression analysis, with the lagged time series of the long-term trend error terms of the APT factors, is used to forecast the movement of the industrial index around its long-term trend. Decision lines were developed to implement a market-timing strategy. The results of the study are as follows: • Where the lagged time series of the long-term trend error terms of the APT factors were used as possible predictors, the risk-adjusted return of a markettiming strategy was 6, 41 percent and 0, 71 percent higher than that of a buyand- hold strategy for periods one and two respectively. • Where the lagged time series of the first-order difference of the long-term trend error term of the APT factors were used as possible predictors, the riskadjusted return of the market-timing strategy was 10,40 percent and 1,04 percent higher than that of a buy-and-hold strategy for periods one and two respectively. The main conclusion of the study is that the APT and a market-timing strategy are theoretically and practically reconcilable on the JSE. The main recommendations of the study are the following: (1) systematic risk factors, other than macroeconomic factors, should be identified in order to increase the forecasting value of these factors in the second period of the study; (2) each step of the model developed in this study should be repeated on every index of the JSE; and (3) the influence of transaction costs and dividends on the potential benefits of a market-timing strategy should be determined. / Business Management / DCom (Sakebestuur)

本論文目的在於探討「異質期望」(heterogeneous expectations)、「資訊密度」(information arrival intensity)、以及「跳躍風險」(jump risk) 這些因素對於期貨價格的影響，並且透由「跨期模型」(intertemporal models) 的建立，推導出具有封閉解形式的期貨價格理論公式。 誠如 Harrison and Kreps (1978) 所言：除非所有市場參與者的行為方式完全相同、而且他們都打算抱著股票直到永遠，否則「投機交易」(speculation transactions) 與「異質期望」就不可能自市場當中滅絕。有鑑於此，本論文在第二章中討論「異質期望」對於期貨價格的影響；同時為了反映交易者看法可能會隨時間演進而發生改變的可能性，「調整效果」(adjustment effects) 是本章另一個討論重點；第三、為了區別期貨契約與遠期契約的基本差異，「利率」這個隨機因子也被納入模型當中。由「部分均衡」(partial equilibrium) 觀點下具有封閉解形式的期貨價格公式來觀察，這三個重要因素以及彼此間存在著的複雜交互作用，可以協助解釋一些實證現象與重要變數之間的關係。 第三章主要是借用Clark (1973) 與Chang et al. (1988) 「資訊時間」(information time) 的概念，取代一般模型所使用的「日曆時間」(calendar time) 設定方法，並且額外納入「利率」與「便利所得」(convenience yield) 這兩個廣為一般期貨定價文獻所認定的重要隨機因素，推導出「部分均衡」觀點下的期貨價格封閉解。根據1998/7/21 至 2003/12/31 台灣期交所「台灣證券交易所總加權股價指數期貨」的實證結果來看，本章模型的定價績效不僅勝過「持有成本模型」(the cost of carry model)，也比同時考慮「利率」與「便利所得」兩個隨機因子的「日曆時間」模型要來的好。 第四章則是嘗試結合Hemler and Longstaff (1991) 的「無偏好模型」(preference-free model) 以及Merton (1976) 的「跳躍」(jumps) 設定，重新推導「一般均衡」(general equilibrium) 模型下、考慮「跳躍風險」(jump risk) 後的期貨價格封閉解。根據本章各種比較靜態與模擬分析的結果顯示，整個經濟體系或是「狀態變數」(state variables) 的安定程度，決定了市場變數間的關係；另一方面，這些關聯會因為「跳躍風險」規模的遞增 — 不管是肇因於「發生機率」(occurring probability) 或是「衝擊效果」(impulse effect) — 而變的更加不可預測。 / The dissertation contains three essays on intertemporal futures pricing models allowing for heterogeneous expectations, information-time based setting, and jump risk. As Harrison and Kreps (1978) have noted, unless traders are all identical and obliged to hold a stock forever, speculation would not extinguish in market, and heterogeneity in expectations yields whereby. The first essay develops intertemporal futures pricing formulas accounting for such reality, adjustment effect, and stochastic interest rate in a partial-equilibrium sense. The closed-form solutions show that the three factors complicated with each others can help to explain some existing empirics on relationships between futures prices and other important market variables such as indeterminate converging pattern. The second essay extends Chang et al. (1988) option pricing model to derive futures prices with information-time based processes. Stochastic interest rate and convenience yield are also taken into account to derive closed-form formulas. According to empirical results of transaction data of TAIEX index and its corresponding TFETX futures contract through 1998/7/21 to 2003/12/31, the analytic solution performs better than the cost of carry model and its calendar-time based counterpart, especially when information arrival intensity estimates become larger. The last essay combines Hemler and Longstaff’s (1991) preference-free model and Merton’s (1976) jump setting to measure effects from jump risk and a futures pricing formula is derived in its closed-form as well. According to miscellaneous comparative static and simulation results, the bounded degrees of state variables, or economy, affect co-varying extents among variables, while the increasing jump risk, including the size of occurring probability and its corresponding impulse effect, makes them un-tractable.

As a result, foreign exchange earnings from tourism surged by 2.6 times, from NT$17.12 billion (US$521.95 million) to an estimated NT$44.50 billion (US$1.36 billion). These results and reviews demonstrate that Taiwan is becoming a major destination for travelers worldwide. Car carter service become a popular way for visitors to explore Taiwan on their own, therefore more and more online car carter service platforms are being set up. Platform pricing model is not set up by user charge alone, how users interact on the platform is also considered. Platform controller attract users who can cause positive cross-side network effect by offering them better price so that they can attract users who are willing to pay the fee. This research depends on two-side market theory to explain how online car carter platforms attract users to enter their platforms, design interaction mechanism and set rules to allow users to use platforms easily. Depending on different point of views, every online car carter service platform has its own design. Therefore, this research also depends on the business model and the eco-system on platform theory to analyze car carter service platform. After understanding how platforms design interaction mechanism, platform pricing model is then discussed. Every platform has its own pricing model, because of different design. This research analyzes platform pricing model by subsidy rules from previous studies. By analyzing three online car carter service platform cases, this research concludes that platforms have different interacting mechanisms because of website design purpose and user dating purpose. This research demonstrates which subsidy rules are used on online dating platform and how these platform create their own eco-system to maintain the platform.

Socially responsible investing has presented itself as a growing, multifaceted, advanced and sophisticated investment philosophy. Socially responsible investment (SRI) involves incorporating social, ethical and responsible investment objectives with financial investment objectives during the investment decision-making process. Social, ethical and responsible investment objectives are set in line with environmental, social and corporate governance (ESG) criteria which are established within the SRI strategy followed. SRI strategies include screening (negative, positive and best-of-sector), shareholder activism and cause-based investing. Although international SRI markets such as that of the United States of America and the United Kingdom are sophisticated and established markets, the South African SRI market is still relatively new and is yet to reach its full potential. Thus, as a growing market, little research regarding the long term risk-adjusted performance of SRI funds in South Africa has been conducted. The long term risk-adjusted performance of the sample of SRI funds was measured through the use of five risk-adjusted performance measures, namely the Treynor ratio, Sharpe ratio, Jensen’s alpha, Sortino ratio and Omega ratio, and through the use of three performance measurement models which included the capital asset pricing model (CAPM), Fama-French three-factor model and Carhart four-factor model. The risk-adjusted performance of the sample of SRI funds was measured with the intent to establish if these funds out- or underperformed against three benchmark categories, namely the Financial Times Stock Exchange/Johannesburg Stock Exchange (FTSE/JSE) SRI Index, a matched sample of conventional investment (non-SRI) funds and the FTSE/JSE All Share Index. The probable effect of the 2007/08 global financial crisis was also measured to analyse whether such a hazardous market event affected the performance of the SRI funds. According to the results and findings, the risk-adjusted performance of the SRI funds has improved over the research period. However, the SRI funds neither outperformed nor underperformed against the three benchmark categories over the research period. The performance measurement models’ analysis indicated that the SRI funds were less sensitive to market fluctuations, more exposed to small capitalisation portfolios, more growth-oriented, and exhibited significant momentum after the period of the 2007/08 global financial crisis. Furthermore, the analysis indicated that the SRI funds significantly underperformed against the non-SRI funds during the Performance of socially responsible investment funds in South Africa research period. Mixed results were obtained with regards to the probable effect of the 2007/08 global financial crisis on the performance of the SRI funds.
