This thesis provides more precise characterisation of patterns, causes and consequences of takeover activity in Australia over three decades spanning from 1972 to 2004. The first contribution of the thesis is to characterise the time series behaviour of takeover activity. It is found that linear models do not adequately capture the structure of merger activity; a non-linear two-state Markov switching model works better. A key contribution of the thesis is, therefore, to propose an approach of combining a State-Space model with the Markov switching regime model in describing takeover activity. Experimental results based on our approach show an improvement over other existing approaches. We find four waves, one in the 1980s, two in the 1990s, and one in the 2000s, with an expected duration of each wave state of approximately two years. The second contribution is an investigation of the extent to which financial and macro-economic factors predict takeover activity after controlling for the probability of takeover waves. A main finding is that while stock market boom periods are empirically associated with takeover waves, the underlying driver is interest rate level. A low interest rate environment is associated with higher aggregate takeover activity. This relationship is consistent with Shleifer and Vishny (1992)'s liquidity argument that takeover waves are symptoms of lower cost of capital. Replicating the analysis to the biggest takeover market in the world, the US, reveals a remarkable consistency of results. In short, the Australian findings are not idiosyncratic. Finally, the implications for target and bidder firm shareholders are explored via investigation of takeover bid premiums and long-term abnormal returns separately between the wave and non-wave periods. This represents the third contribution to the literature of takeover waves. Findings reveal that target shareholders earn abnormally positive returns in takeover bids and bid premiums are slightly lower in the wave periods. Analysis of the returns to bidding firm shareholders suggests that the lower premiums earned by target shareholders in the wave periods may simply reflect lower total economic gains, at the margin, to takeovers made in the wave periods. It is found that bidding firms earn normal post-takeover returns (relative to a portfolio of firms matched in size and survival) if their bids are made in the non-wave periods. However, bidders who announce their takeover bids during the wave periods exhibit significant under-performance. For mergers that took place within waves, there is no difference in bid premiums and nor is there a difference in the long-run returns of bidders involved in the first half and second half of the waves. We find that none of theories of merger waves (managerial, mis-valuation and neoclassical) can fully account for the Australian takeover waves and their effects. Instead, our results suggest that a combination of these theories may provide better explanation. Given that normal returns are observed for acquiring firms, taken as a whole, we are more likely to uphold the neoclassical argument for merger activity. However, the evidence is not entirely consistent with neo-classical rational models, the under-performance effect during the wave states is consistent with the herding behaviour by firms.

This paper addresses the problem of a failing net debt approach; deposited funds rarely compensate the cost of debt. Venturing into operational credit facilities, the study evaluates the efficiency and feasibility of transitioning into fully cash-free liquidity management. The study takes a holistic approach and evaluates the research questions from the perspective of management through case studies on four smaller Swedish industrial firms. The study finds that there is substantial potential to free up capital; return on equity could have been boosted by an annual 5-10 percent including substantial one-off distributions. The study also concludes that Agency reasons are strong reasons for why firms are carrying material cash reserves. Through qualitative interviews, the study identifies several additional, but not less important, obstacles in the way of a full out cash-free transition. Most significantly, the financial system is not offering fully committed long term operational credit facilities and operating across different jurisdictions complicates the consolidation of liquidity. The study concludes that the matter would not have vast negative implications on real business activities, although further research would be required in regard to an extended debt overhang problem. / Uppsatsen kretsar kring den fallerande logiken med begreppet nettoskuld; tillgodohavanden på bank genererar sällan upp för kostnaden relaterad till motsvarande skuld. Med utgångspunkt i operationella kreditstrukturer utvärderas möjliga effektivitetsvinster och genomförbarheten av en fullständig övergång till kassa-fri likviditetshantering. Studien har ett holistiskt angreppssätt och utvärderar frågeställningarna från ett management-perspektiv genom fallstudier på fyra mindre svenska industriella bolag. Studien finner betydande möjligheter att frigöra kapital; årliga avkastningen på eget kapital hade kunnat öka med 5–10 procent och betydande engångsutdelningar hade varit möjliga. Studien finner vidare att agentteorin är en stark anledning till att bolag bär betydande kassapositioner. Genom kvalitativa intervjuer identifierar studien ytterligare, men ej desto mindre betydande, hinder för en kassa-fri övergång. Mest betydelsefullt, är att nuvarande finansiella system inte erbjuder för syftet fullgoda kreditstrukturer, samt det faktum att företag med verksamhet över olika jurisdiktioner upplever juridiska svårigheter med att konsolidera likviditet. Studien drar slutsatsen att en övergång inte skulle medföra betydande negativa konsekvenser för den operativa affärsverksamheten, men identifierar samtidigt att ytterligare studier skulle vara nödvändiga framförallt kring hur finansiella incitament kopplade till agent-teorins ’debt overhang’ skulle förändras vill en övergång till en fullt garanterad operationell kreditstruktur.
