Keywords Short-term investors, Long-term investors, institutional investors, managerial myopia, investement, intangibles, employee satisfaction, bank performance, investor horizon Objectives The objective of my thesis is to investigate the real effects of short-term and long-term investor ownership on corporate policies. It aims at understanding how the ownership structure might affect firms’ decisions. Design / methodology / approach My thesis contains a survey and three empirical contributions. For each paper, I investigate a potential effect of long-term or/and short-term institutional ownership on corporates or banks. I study mostly the US market, over the 1980-2014 period and use common econometric methodologies to obtain my results and assess their robustness. Empirical findings / expected outputs 1) I show that banks which entered the last financial crisis with a greater short-term ownership, experienced larger price drops. It challenges the common view that more bank capital is always better.
2) I show that long-term ownership is beneficial for developping employee satisfaction (a long-term oriented intangible asset)
3) I propose a test to assess the best strategy for a firm to develop long-term ownership: attracting outsiders or making current shareholders holding their shares longer. » Research contribution / practical implications / Originality My thesis leads to concrete corporate and regulatory implications regarding which shareholder base to promote and how. The debate whether long-term ownership has a real impact on firms and wether it should be encouraged is a very topical one. For instance, in France, a law, which promotes long-term ownership in listed companies, was recently passed. See also, in the UK, the Kay Report, and in the US, Clinton’s proposal to encourage long-term investment.

|Thesis title||Regulation, Liquidity risk and portfolio management|
|JEL Classification||G1, G00|
|Objectives||The objective is to see the impact of liquidity on the portfolio. The idea is first to quantify a portfolio liquidity, then find a new framework for portfolio choice under liquidity constraint and optimal portfolio execution.|
|Design / methodology / approach||-For liquidity measure: aggregate different liquidity measures to capture the different aspect of liquidity
– Integrate liquidity in the merton model using marginal supply curve
– Integrate liquidity in the portfolio execution using marginal supply curve
|Empirical findings / expected outputs||In progress|
|Research contribution / practical implications / Originality||There is no consensus in the community and no standard approach for liquidity risk.
-New liquidity measure integrating bond features ( amount, duration, sector, rating…)
– New framework for portfolio choice under liquidity constraint
