Toeholds and takeover probability: implications for investment strategies

2009

PurposeThe purpose of this paper is to propose various toehold indicators and analyse whether the models incorporating these indicators can be used to establish investment strategies.Design/methodology/approachLogistic regression is used to test toehold indicator significance.FindingsThe results reflect that the designed measures are positively correlated to the likelihood of launching a takeover, although the power of the models to predict out‐sample takeovers is moderate, between 60.71 percent and 71.59 percent. The indicators allow us to design strategies which offer positive abnormal returns. In particular, abnormal return over the Fama‐French factors is 0.5 percent.Originality/valueToe…

The European sovereign debt market: from integration to segmentation

2013

This paper investigates the impact of European Monetary Union (EMU) and of the recent financial and fiscal crisis on the integration of the European sovereign debt market using annual data 1992–2010. The panel regression dependent variable is time-varying market linkages computed from daily realised correlations between sovereign bond returns for 13 European economies and Germany. The results indicate that the elimination of currency risk following the implementation of EMU led to a fundamental and significant one-off increase in integration. The net impact of fiscal fundamentals was negligible up until 2009 as the markets seemed to be pricing in a potential bailout for member states in cri…

A Spatial Difference-in-Differences Estimator to Evaluate the Effect of Change in Public Mass Transit Systems on House Prices

2014

Evaluating the impact of public mass transit systems on real-estate values is an important application of the hedonic price model (HPM). Recently, a mathematical transformation of this approach has been proposed to account for the potential omission of latent spatial variables that may overestimate the impact of accessibility to mass transit systems on values. The development of a Difference-in-Differences (DID) estimator, based on the repeat-sales approach, is a move in the right direction. However, such an estimator neglects the possibility that specification of the price equation may follow a spatial autoregressive process with respect to the dependent variable. The objective of this pap…

Risk aversion connectedness in five European countries

2018

Abstract In this paper we compute an aggregate index of risk aversion and indices of vulnerability and the contribution to systemic risk aversion for five European countries. The variance risk premium proxies risk aversion. The contribution to the literature is twofold. First, this is the first study estimating not only the common component, but also indices of directional connectedness among variance risk premia. Second, it is the first to estimate the interconnections by means of a FIVAR model, in order to account for long memory. Our analysis indicates measures of total and directional connectedness unlike those that would be obtained with the use of a short memory VAR. These differences…

THE CARMA INTEREST RATE MODEL

2014

In this paper, we present a multi-factor continuous-time autoregressive moving-average (CARMA) model for the short and forward interest rates. This model is able to present an adequate statistical description of the short and forward rate dynamics. We show that this is a tractable term structure model and provides closed-form solutions to bond prices, yields, bond option prices, and the term structure of forward rate volatility. We demonstrate the capabilities of our model by calibrating it to a panel of spot rates and the empirical volatility of forward rates simultaneously, making the model consistent with both the spot rate dynamics and forward rate volatility structure.

Twitter sentiment as a weak signal in venture capital financing

2021

Abstract How do venture capitalists (VCs) incorporate weak and strong signals in the valuation of technology-based startups? Based on a sociocognitive perspective of signaling theory, we introduce Twitter sentiment as a novel and weak signal, which we juxtapose with patents as a traditional, strong signal. While we find a positive association between both signals and VCs' venture valuations, our results reveal that Twitter sentiment does not correlate with actual long-term investment success, whereas patents do. Additionally, we identify and test novelty and experience characteristics (i.e., startup age and VC firm experience) as boundary conditions for our proposed signal-valuation relatio…

Investor Motivations in Investment-Based Crowdfunding

2017

International audience; We investigate determinants of investment decisions in investment-based (equity and real estate) crowdfunding, using a novel investment-, investor- and campaign-level database. We find that this market is a man’s world, with nearly 93% of investments made by men. We find that women invest less in the riskiest investments but more in safer ones. These findings are better explained by differences in risk aversion than differences in overconfidence between men and women. Investors located in an area considered more "sociable" (socially friendly) also invest more, but only if the investor is a woman. Overall, the findings contribute to our understanding of how investment…

La ville, la raison et le rêve : entre théorie et utopie

1996

City, reason and dream : between theory and utopia. — This paper aims at comparing two kinds of discourses about the city, that of the microeconomics of cities, which is admitted in the realm of science, and that of Utopian cities, which is not. We analyse the processes of thinking which lead respectively to theory and utopia, then we compare the ideas of man and society upon which they are grounded. Finaly, we try to enhance the similarities and disimilarities between the two series of urban space representations to which these approaches lead. This comparison may contribute to a better understanding of the real nature of the theoretical discourse and lead both to a relativization and a va…
