This thesis consists of five individual essays and an introductory chapter. The essays are all in the field of industrial dynamics and more specifically focus on firm entry and exit in Swedish industrial sectors. The essays mainly contribute to the empirical literature on entry and exit. In four of the five essays, panel data methods are used in the empirical investigation. The first essay presents the patterns of entry and exit in industrial sectors in Sweden and studies the importance of different determinants of entry and exit rates in industries. The second essay focuses on the relationship between entry and exit. The third essay has a regional perspective, focusing on regional determinants of entry and exit. It also investigates the importance of the differences in industry structure for differences in entry and exit rates across regions. The fourth chapter uses the theory of product life cycle to investigate how knowledge intensity differs in entering and exiting firms in different stages of the product life cycle. The fifth and last essay focuses on the importance of firm demography, in terms of firm size and age, for the decision to perform process R&D, product R&D or combine process with product R&D.

Syfte: Studien har utrett om aktiesplit genomförda på Stockholmsbörsen under åren 2004-2008 genererat överavkastning och i sådana fall om det har funnits några skillnader i överavkastning beroende på företagens storlek. Teori: Den effektiva marknadshypotesen, framförallt i dess semistarka form, har utgjort en teoretisk referensram för arbetet. Metod: En kvantitativ deduktiv forskningsansats har tillämpats med eventstudiemetodik som grund. Undersökningen behandlar en femårsperiod mellan 2004-2008 där ett urval av 56 stycken splitar mötte uppsatta kriterier. Dessa delades in i tre undergrupper beroende på bolagens kapitalstorlek vid splitgenomförandet. Kursdata för 250 dagar innan spliten och 250 dagar efter har samlats in för berörda bolag med hänsyn till splitdagen. OMXSPI har använts som jämförelseindex. Resultat: Resultatet tillsammans med hypotesprövning visar att överavkastning i samband med aktiesplit har påträffats för hela populationen under mätperioden. Ett möjligt samband mellan storleken på bolag och omfattningen överavkastning har även upptäckts. Den enskilt största överavkastningen uppmättes på splitdagen. Analys: En analys av resultaten pekar på att marknaden uppfattat aktiesplit som en positiv nyhet och i linje med tidigare forskning har det funnits överavkastning i tiden runt en aktiesplit. Vid uteslutande av en undergrupp som inte klarat hypotestestet kunde sambandet mellan företagsstorlek och omfattningen överavkastning till viss del bekräftas som negativt. Slutsats: Investerare har kunnat generera överavkastning i samband med aktiesplit på Stockholmsbörsen mellan 2004-2008. Resultatet tyder på ett negativt samband mellan företagsstorlek och överavkastning, däremot kan inte sambandet bekräftas tillfullo. / Purpose: The study has investigated whether or not stock splits on the Stockholm Stock Exchange during the years 2004-2008 generated positive abnormal return and in such case, has there been any difference in the positive abnormal return depending on firm size. Theory: The efficient market hypothesis, especially in its semi-strong form, has provided a theoretical framework for the essay. Method: A quantitative deductive research approach is applied with event study methodology used as basis. The study concerns a five-year period 2004-2008, where a selection of 56 splits met set criteria. These were divided into three groups depending on their capital size at the split date. The price data for 250 days before the split, and 250 days after were collected for the companies with regard to split day. The same data was collected for OMXSPI that was used as a benchmark. Results: The result together with hypothesis testing shows that positive abnormal return associated with stock split has been found in the overall population. A possible correlation between the firm size and the extent of positive abnormal returns has also been discovered. The single greatest positive abnormal return was measured on the split date. Analysis: An analysis of the results indicates that the market perceived stock split as positive news. There has been a positive abnormal return around the time of a stock split in line with previous research. The exclusion of a subgroup that failed hypothesis test revealed a partly confirmed negative relationship between firm size and the amount of positive abnormal returns. Conclusion: Investors have been able to generate positive abnormal returns in association with stock split on the Stockholm Stock Exchange from 2004 to 2008. The results suggest a negative correlation between firm size and positive abnormal returns, however, the correlation is not fully confirmed.

This thesis investigates the determinants of UK corporate cash holdings between 1980 and 2012. The global and long term phenomenon of corporate cash pilling has drawn significant attention from researchers. Similarly, this study aims at shedding light on the empirical relationship between cash holding and specific firm characteristics. Our preliminary research incorporates a comprehensive literature review. Towards this end, the relevant financial theory is presented and the previous empirical studies are highlighted. Afterwards, the expected results of our research are synthesized into a set of distinct hypotheses and tested with regression analysis. The empirical findings suggest that cash holdings are positively related to investment opportunity, as R&D and market to book ratio. Cash ratio is also positively related to industry cash flow volatility and negatively affected by cash flow, net working capital, capital expenditures, leverage, tax expenses, age and size. Regarding the development of the determinants of cash holdings, the study indicates that three major variables influenced cash holdings over the years of analysis. In particular, leverage, tax regime and capital expenditures significantly affect the corporate liquidity in UK market. Furthermore, the results suggest that cash holdings are mostly defined by trade off theory. Indeed, our findings offer stimulating insights on the factors that determine the firms’ cash holdings during the past three decades. These findings may be beneficial for financial managers, investors and consultants. / Στην παρούσα διατριβή εξετάζονται οι προσδιοριστικοί παράγοντες του δείκτη μετρητών σε επιχειρήσεις του Ηνωμένου Βασιλείου μεταξύ των ετών 1980 και 2012. Η διακράτηση μετρητών αποτελεί παγκόσμιο φαινόμενο και λαμβάνει της ανάλογης προσοχής από πληθώρα ερευνητών. Σε αυτή τη βάση, η μελέτη αυτή έχει ως στόχο να ρίξει φως σχετικά με την εμπειρική σχέση μεταξύ του δείκτη μετρητών και τα συγκεκριμένα χαρακτηριστικά που επηρεάζουν την ρευστότητα στις επιχειρήσεις διαχρονικά. Αρχικά η έρευνα ενσωματώνει μια βιβλιογραφική ανασκόπηση. Προς το σκοπό αυτό, οι σχετικές οικονομικές θεωρίες και οι προηγούμενες εμπειρικές μελέτες παρουσιάζονται. Στη συνέχεια, τα αναμενόμενα αποτελέσματα της έρευνας συντίθενται σε ένα σύνολο διακριτών υποθέσεων και δοκιμάζονται με ανάλυση παλινδρόμησης. Τα εμπειρικά ευρήματα υποδηλώνουν ότι ο δείκτης μετρητών σχετίζεται θετικά με τις επενδυτικές ευκαιρίες, τις δαπάνες Ε&Α και τον λόγο της αγοραίας προς τη λογιστική αξία των βιβλίων της επιχείρησης. Ο δείκτης μετρητών επίσης, σχετίζεται θετικά με την μεταβλητότητα των ταμειακών ροών του κλάδου και επηρεάζεται αρνητικά από τις ταμειακές ροές, το καθαρό κεφάλαιο κίνησης, τις κεφαλαιακές δαπάνες, την μόχλευση, τα φορολογικά έξοδα, την ηλικία και το μέγεθος των επιχειρήσεων. Όσον αφορά την εξέλιξη των προσδιοριστικών παραγόντων των ταμειακών ρευστών διαθεσίμων, η μελέτη δείχνει ότι τρεις είναι οι κύριες μεταβλητές που επηρεάζουν τη διακράτηση μετρητών κατά τη διάρκεια των χρόνων της ανάλυσης. Ειδικότερα, η μόχλευση, το φορολογικό καθεστώς και τις κεφαλαιακές δαπάνες επηρεάΖουν σημαντικά την απόφαση για εταιρική ρευστότητα στην αγορά του Ηνωμένου Βασιλείου. Επιπλέον, τα αποτελέσματα δείχνουν ότι η διακράτηση μετρητών ακολουθεί κυρίως την trade off θεωρία. Πράγματι, τα ευρήματά προσφέρουν χρήσιμες γνώσεις σχετικά με τους παράγοντες που καθορίζουν τη διακράτηση μετρητών των επιχειρήσεων κατά τη διάρκεια των τριών τελευταίων δεκαετιών. Τα ευρήματα αυτά μπορεί να είναι επωφελή για οικονομολόγους, επενδυτές και συμβούλους.

本研究之目的為透過中國大陸A股、B股公司財務報表之比較，探討相對於中國大陸會計準則（PRC GAAP），國際財務報導準則（IFRS）是否更具審慎性。研究方法採Khan and Watts在2009年發展之C_Score來衡量財務報表審慎性。研究期間為2001年初至2006年底，研究標的為在上海或深圳證券交易所同時掛牌上市A、B股之公司（意即同時按PRC GAAP及IFRS編製兩套財務報表之公司）。實證結果如下： 1.A股市場之C_Score小於B股市場之C_Score，顯示相對於依照PRC GAAP編製之財務報表，依照IFRS編製之財務報表其審慎性較高。 2.無論是針對個別產業進行A股、B股之比較，或是針對A股或B股市場進行跨產業比較，均證實產業因素會對財務報表之審慎性造成影響。 3.無論是針對A股或B股市場進行事務所規模之比較，均顯示在中國大陸，四大事務所查核之財務報表，其審慎性不但不如非四大事務所，而且在A股市場甚至不具審慎性。 / Using C_Score developed by Khan Watts(2009) to test the financial statements of Chinese companies which have both the A-Share and B-Share listed on the stock exchange marke of Shanghai and Shenzhen during 2001 to 2006, this study aims to examime whether International Financial Reporting Standards(IFRS) are more conservative than People’s Republic of China’s generally accepted accounting principles(PRC GAAP). The empirical results are as follows: 1.The average C_Score of A-Share companies is smaller than B-Share Companies, which means that, as compared to PRC GAAP-based financial statements, IFRS-based financial statements are more conservative. 2.Regardless of whether the comparison is between A-Share and B-Share companies in a specific industry, or between industries in a specific stock market, the results show some industry effect on the conservatism of financial statements. 3.Regardless of whether the stock is traded on the A-Share or B-Share market, the results show that in China, financial statements audited by Big 4 are not more conservative than non Big 4. In fact, for stocks traded on the A-Share stock market, financial statements audited by Big 4 are not conservative at all.

Consistente com a literatura, o porte de auditoria tem sido utilizado como proxy de qualidade do serviço, e classificado como auditoria Big 6 e não-Big 6, sendo quanto maior o porte, maior a qualidade. A pesquisa abrangeu os estudos que utilizam acumulações discricionárias na estimação da manipulação da informação contábil. Por meio de uma revisão sistemática da literária, foram selecionadas 14 pesquisas empíricas, abrangendo Estados Unidos, Europa e Ásia. Com base na análise dos seus aspectos substantivos e metodológicos, a conclusão é que a magnitude da manipulação da informação contábil não é uniforme nos países estudados sugerindo que os ambientes cultural, institucional e legal podem influenciar a capacidade da auditoria em mitigar a ação discricionária dos gestores. / This study examines the relation between the audit firm size and the manipulation of accounting information. Consistent with the literature, firm size has been used as a proxy for quality of service, and classified as Big 6 and non-Big 6, and the larger the size, the better the quality. The survey covered the studies that use discretionary accruals in the estimation of earnings management Through a systematic review of literature, 14 empirical researches were selected, covering the United States, Europe and Asia. Based on the analysis of their substantive and methodological issues, the conclusion is that the magnitude of the accounting manipulation of information is not uniform in the countries surveyed suggesting that the cultural, institutional and legal environments may influence the ability of the audit to mitigate managers’ discretion.

Inledning: Historiskt sett har IPO:er ofta varit underprissatta vilket har resulterat i att de i genomsnitt haft en hög initial avkastning, det vill säga, hög avkastning den första handelsdagen. Detta har skapat en uppfattning om att nyintroduktioner är ett bra investeringsalternativ för de som vill ha en avkastning utöver det normala. Syfte: Syftet med uppsatsen är att studera huruvida aktiers utveckling på kort och lång sikt påverkas av variabler som bolagets storlek, ålder, branschtillhörighet, noteringsperiod och könsfördelning i styrelsen. Syftet är också att undersöka huruvida IPO:er är underprissatta och om de underpresterar på lång sikt. För att studera detta har aktier noterade på Stockholmsbörsen, Aktietorget och First North mellan år 2013 och 2014 analyserats. Metod: För att kunna genomföra denna studie har ett kvantitativt tillvägagångssätt tillämpats. Vidare har en deduktiv ansats använts då avsikten var att analysera det insamlade materialet utifrån tidigare forskning. Urvalet består av 56 bolag där sekundärdata inhämtats via Nasdaq OMX, Nordnets- och Avanzas webbsida samt Skatteverket. Teori: Den teoretiska referensramen som studien baseras på består av teorier som har skapats kring hur IPO:er presterar på kort och lång sikt och varför de presterar som de gör. Vidare presenteras tidigare forskning kring hur könsfördelning i bolagsstyrelser kan påverka bolagens utveckling. Resultat och slutats: Resultatet visade att IPO:er på kort sikt blir överprissatta då de haft en negativ initial utveckling. Resultatet visade vidare att IPO:er överpresterar på lång sikt samt att de mest underprissatta IPO:erna presterar bäst. För de oberoende variablerna storlek, ålder, branschtillhörighet, noteringsperiod och könsfördelning i styrelsen kunde inga signifikanta samband återfinnas. / Introduction: Historically, IPO’s have often been underpriced, which has resulted in a high initial return on average, i.e. high return on the first trading day. This has created the perception that new introduction is a good investment option for those who want an abnormal return. Purpose: The purpose of this study is to examine whether the short- and long-term performance of IPO’s are affected by variables as firm size, firm age, industry affiliation, issue period and gender diversity on board of directors. The purpose is also to determine whether IPO’s are underpriced and if they underperform in the long run. To study this, Initial Public Offerings on First North, Aktietorget and Stockholmsbörsen during the period of 2013 to 2014 have been analyzed. Methodology: To implement this study, a quantitative approach has been applied. Furthermore, a deductive approach was used since the purpose was to analyze the collected material based on previous research. The data selection consists of 56 firms were the secondary data has been obtained from Nasdaq OMX, Nordnet website, Avanza website and The Swedish Tax Agency. Theory: The theoretical frame that the study is based on consists of theories that were created regarding how IPO’s perform in short- and long-term and why they perform as they do. Furthermore, earlier research is presented which examine how gender diversity in board of directors affect corporate performance. Result and conclusions: The result in this study shows that in the short run, IPO's are overpriced due to a negative initial return. Further, the result show that IPO's outperform other companies, and the most underpriced shares perform better in the long run. For the dependent variables size, age, industry affiliation, listing period and gender diversity, no relationship of statistical significance could be found.

Inom revisionsprofessionen sker en förskjutning i könsbalansen. Andelen kvinnor ökar successivt. Tidigare forskning, främst från andra länder än Sverige, tyder på att kvinnliga revisorer kan leverera högre revisionskvalitet än manliga revisorer. Syftet med denna studie är därför att beskriva och analysera eventuella skillnader i kvalitet mellan manliga och kvinnligarevisorer i Sverige. Likaså tyder tidigare forskning på att större revisionsbyråer (Big 4) kan ha högre revisionskvalitet än mindre byråer (icke Big 4), varvid syftet även är att beskriva och analysera om kvaliteten påverkas av byråtillhörighet.För att mäta revisionskvalitet har träffsäkerhet och tydlighet i going concern-varningars formuleringar samt utfärdandet av övriga anmärkningar i revisionsberättelsen använts. Studien baseras på data från 1407 aktiebolag som gått i konkurs under år 2014. Informationen grundar sig på dessa aktiebolags årsredovisningar och revisionsberättelser året före konkurs.Datamängden har sedan testats genom chi-2 tester och analyserats gentemot tidigare forskning på området.Resultatet visar inga signifikanta skillnader mellan manliga och kvinnliga revisorer när det gäller träffsäkerhet, tydlighet samt övriga anmärkningar. Däremot visar resultatet att det finns signifikanta skillnader mellan Big 4 och icke Big 4 byråer. De större byråerna har inte bara en högre träffsäkerhet i going concern-varningar utan är även tydligare i formuleringarna avdessa. Gällande övriga anmärkningar återfinns inga signifikanta skillnader men resultatet antyder att revisionsbyråer tillhörande Big 4 utfärdar färre övriga anmärkningar än icke Big 4 byråer.Sammanfattningsvis visar resultatet, till skillnad från vissa andra studier som genomförts på området, att revisorns kön inte har någon betydelse för revisionskvaliteten. Däremot indikerar resultatet att revisionsbyråer tillhörande Big 4 har en högre kvalitet i sin revision än icke Big 4 byråer, vilket är i linje med tidigare forskning på området. / Within the audit profession there is a shift in the gender balance, where more and more women are entering the industry. Previous research, mainly from other countries than Sweden, indicates that female auditors have a higher quality in their auditing than male auditors. The purpose of this study is therefore to describe and analyze possible differences in audit quality between male and female auditors in Sweden. Likewise, previous research indicates that big audit firms may have a higher quality in their auditing than small audit firms. The purpose is therefore also to describe and analyze if audit quality is affected by audit firm size.Accuracy in going concern opinions, wording in going concern-opinions and other audit opinions in the audit report were used to measure audit quality. The study is conducted on data from 1407 limited companies, which filed for bankruptcy in 2014. The information comes from financial statements and audit reports from the year before bankruptcy. The data was later on tested by chi-2 tests and analyzed together with previous research in the area.The result provides no significant differences between male and female auditors when it comes to accuracy, wording and other audit opinions. However, the result shows significant differences between Big 4 and non Big 4 audit firms. Big 4 firms are not only more accurate, but also use a clearer wording in their going concern opinion. Regarding other audit opinionsthere are no significant differences but the result still indicate that Big 4 audit firms issue less other opinions than non Big 4 firms. / <p>Betyg B, 170602</p>

Syfte: Företags kassaflöden och vinster samt staters inkomster påverkas av hur mycket skatt som betalas av företag. Resultat i tidigare forskning om företagsstorlekens betydelse för effektiva skattesatser är motstridiga. Utelämnande av andra variabler som i vissa studier har visats ha signifikanta effekter på effektiva skattesatser kan vara en anledning till denna motstridighet. Sådan forskning har inte genomförts i Sverige enligt författarnas kännedom. Därför undersöks i denna studie effekterna av variabler som mäter storlek, skuldsättning, kapitalintensitet, forsknings- och utvecklingsintensitet samt lönsamhet på effektiva skattesatser hos företag med svensk företagsledning eller koncernledning. Syftet med detta är att ge en bild av vilka faktorer som kan förklara variationer mellan dessa företags skattebörda. Metod: Fem hypoteser om samband mellan variabler deduceras utifrån teorier och tidigare forskning. 3 593 kvantitativa observationer från 702 noterade företag och 6 år samlas in från databasen Retriever Business. Den longitudinella datan används i en regressionsanalys som testar de fem hypoteserna. Resultat: Denna studie bidrar med empiriskt bevis för ett positivt och signifikant samband mellan företagsstorlek och effektiva skattesatser. Däremot visas inte effekterna av skuldsättning, kapitalintensitet, FoU-intensitet och lönsamhet på effektiva skattesatser vara signifikanta. Slutsatser: Den slutsats som dras är att företagsstorlek är en indikation på storleken på effektiva skattesatser för företag med svensk företagsledning eller koncernledning. Teorin om politiska kostnader kan användas för att förklara sambandets riktning. / Aim: Cash flows and profits in firms as well as government revenue are affected by how much is paid in corporate taxes. Results in prior research concerning the effect of firm size on effective tax rates are inconsistent. Omitting other variables that have in some studies been proven to have significant effects on effective tax rates can be one cause of this inconsistency. Such research has not been conducted in Sweden to the extent of the authors’ knowledge. Therefore, this study examines the effects of variables that measure size, leverage, capital intensity, research and development intensity, and profitability on effective tax rates for firms with Swedish management or group management. The aim of this is describing which factors that can explain variations between these firms’ tax burdens. Method: Five hypotheses regarding associations between variables are deduced from theories and prior research. 3 593 quantitative observations from 702 publicly listed firms and 6 years are collected from the database Retriever Business. The longitudinal data is used in a regression analysis that tests the five hypotheses. Results: This study provides empirical evidence for a positive and significant association between firm size and effective tax rates. However, the effects of leverage, capital intensity, R&amp;D intensity, and profitability on effective tax rates are not shown to be significant. Conclusions: It is concluded that firm size is an indicator of the size of effective tax rates for firms with Swedish management or group management. The political cost theory can be used in explaining the direction of the association.

<p>This dissertation consists of three major chapters. The first chapter is dedicated to testing a novel gravity model of international trade, while the last two chapters explore cross-country commitment and implementation behavior within the World Trade Organization’s Trade Facilitation Agreement. </p> <p><strong>Chapter 1:</strong> I test a novel theoretical gravity model of international trade on firm-level export data from Colombia in 2018. The model assumes a power law relationship between trade flows and distance, with the distance elasticity resulting from two dynamic processes: firm-export growth captured in a Pareto distribution; and the growth of the distance over which those exports are sold. Although the model has been shown to work well in French data, its usefulness for interpreting data from other countries remains unexplored. I find evidence that the model fails in Colombia because some large firms contradict its assumptions by exhibiting shorter export distances compared to smaller firms in the sample. I hypothesize that these large firms are branches of foreign multinational corporations (MNCs). MNCs’ headquarters constraint the export growth of its affiliates as well as the markets they reach. While I cannot prove firms’ MNC affiliation, I use export sophistication as an imperfect metric to reflect MNC presence. When MNC affiliates are excluded from the sample, firm export distance rises faster with firm size, leading to improved predictions of the distance elasticity of trade in Colombia by the model. These findings have implications not only for the tested model but also for other theories that explain gravity in international trade through firm-level behavior.</p> <p><strong>Chapter 2:</strong> We use a new database of commitments made during the process of ratifying the Trade Facilitation Agreement (TFA) to study variation in countries’ commitment behavior. The TFA is a novel World Trade Organization agreement because it allows developing countries to select commitments from a menu of best practices in trade facilitation, rather than to consent, or not, to a comprehensive package of negotiated commitments. The operation of this <em>à la carte</em> approach to concluding trade agreements is worthy of study in its own right, but the commitment data also offer a high-level description of progress in an international effort to improve border management procedures around the globe. Our study uses data on TFA commitments to describe progress across subcomponents of the agreement. A regression model shows that the number of Type A trade facilitation commitments that a country made in the TFA ratification process depends on its level of development, population size, ability to control corruption, and foreign aid received to support trade facilitation. We use multidimensional scaling techniques to study differences in the content of national commitment bundles. This approach demonstrates that variation in the content of countries’ commitments is closely tied to the number of commitments made.</p> <p><strong>Chapter 3:</strong> This chapter examines the implementation progress of the Trade Facilitation Agreement (TFA) from 2019 to 2023. The TFA, which is the latest World Trade Organization agreement, came into force in 2017. In its novelty, it allows developing countries to set their own implementation schedule and adjust it if needed. This flexibility aligns implementation requirements with the capabilities of signatory countries, but introduces uncertainties in achieving complete global implementation and fully realizing the potential benefits of the agreement. Using data on the notified implementation dates for each measure of the TFA, this study describes the progress made in implementing different subcomponents of the agreement over a period of five years. A regression analysis suggests that the annual rate of progress towards achieving full TFA implementation does not vary based on country characteristics such as GDP per capita, population size, or landlocked status. Assuming that the tendency at which countries implement measures remains unchanged, I project that 95% of developing countries will achieve 95% TFA implementation between the years 2036 and 2047.</p>

依據財務會計理論，附註揭露為整體財務報表的一部份，其目的在提供投資人進行企業評價時所需之攸關資訊。兩稅合一制度實施後，不僅使稅賦型態轉變，會計原則中也新增附註揭露股東可扣抵稅額之規定，因此提供了驗證資本市場與財務報表揭露的機會，本研究即針對股東可扣抵稅揭露是否具有價值攸關性進行測試。 本研究以87年為樣本年度，分析資料完整的317家上市公司，透過Ohlson模型來檢測股東可扣抵稅額之價值攸關性，並處理Ohlson模型中兩個重要的information dynamics，以異常盈餘（xa ）及其他資訊（v）做為模型中的自變數，將財務分析師之財務預測（analysts’forecasts）做為Ohlson模型中其他資訊（other information）之代理變數，以捕捉Ohlson模型中其他資訊對股價的影響。最後，考慮產業及公司規模兩項因素，觀察紡織業與電子業對股東可扣抵稅額揭露之反應以及公司規模對於價值攸關性研究的影響。 實驗結果顯示，無論以現金基礎或應計基礎衡量股東可扣抵稅額，其揭露均具價值攸關性，投資人的確使用財務報表附註揭露中有關股東可扣抵稅額之資訊於企業評價上。其次，異常盈餘與其他資訊皆能捕捉股價之變動。最後，在紡織業與電子業中雖未觀察到股東可扣抵稅額之揭露具有攸關性，但公司規模的因素則無論在全體樣本或各別產業中皆具影響力。 / According to modern accouning theory, footnote disclosures are an intergrated part of the overall financial statements. The purpose of footnote disclosures is to provide value-relevant information in assisting investors’ valuation process. After Taiwan’s 1998 Tax Reform, which intergrates the individual and corporate taxes, the current GAAP requires a footnote disclosure of imputation credits (IC). This provides a good chance to test how Taiwan’s stock market reacts to such disclosuer. The main purpose of this study is to examine the value relevance of IC disclosure to investors’ equity valuation. This study uses Ohlson’s (1995) model to analyze 317 firms listed on Taiwan’s Stock Exchang (TSE) during 1998. To estimate the abcdrmal earings and other information (captured by analysts’ forcasts), this study adopts Dechow, Hutton, and Sloan’s(1999) methodology. We also investigate the effects of industry and firm size on the value relevance of IC disclosure. The empirical results reveal three findings. First, there is a positive association between IC and stock price in TSE. Therefore, the IC disclosure is value relevant to investors’ equity valuation. Second, abcdmal earnings and other information can both explain stock price behavior. Finally, when we focus our sample on the textile and high-tech industries, no significant association between IC disclosure and stock price can be found. When we further consider firm size, however, the value relevance of IC disclosure becomes significant. In other word, the value relevance of IC disclosure may be affected by firm size.
