The Deterring Role of the Medium of Payment in Takeover Contests: Theory and Evidence from the UK

The deterring role of the medium of payment in a takeover contest is analysed from the point of view of the bidder. Cash, debt and equity are considered as alternative mediums of payment, and the bidder equilibrium strategies are specified following the Perfect Bayesian Equilibrium requirements for a signalling game. The model predicts notably that cash offers signal a high‐valuing bidder, strongly determined to acquire the target firm. Moreover, cash offers deter competition better than debt or equity offers. The theoretical results are validated with data from the UK over 1995–96.     

Learning to Play Limited Forecast Equilibria

This paper provides a learning justification for limited forecast equilibria, i.e., strategy profiles such that (1) players choose their actions in order to maximize the discounted average payoff over their horizon of foresight as given by their forecasts and (2) forecasts are correct on and off the equilibrium path. The limited forecast equilibria appear to be the stochastically stable outcomes of a simple learning process involving (vanishing) trembles.Journal of Economic LiteratureClassification Numbers: C72, D83.     

The market value of preventive activities: A contingent-claims approach

We use a contingent-claims approach to determine the market value of preventive investments. We show that the lower the initial probability of accident, the greater is the market value of a reduction in this probability. Besides, at initially low probabilities, ceteris paribus, the market gives a higher value to a reduction in accident probability when aggregate (correlated) catastrophic risks rather than independent ones are involved. The reverse occurs at initially high probabilities.

Auctions and information acquisition: sealed bid or dynamic formats?

The value of an asset is generally not known a priori, and it requires costly investments to be discovered. In such contexts with endogenous information acquisition, which selling procedure generates more revenues? We show that dynamic formats, such as ascending‐price or multistage auctions, perform better than their static counterpart. This is because dynamic formats allow bidders to observe the number of competitors left throughout the selling procedure. Thus, even if competition appears strong ex ante, it may turn out to be weak along the dynamic format, thereby making the option to acquire information valuable. This very possibility also induces the bidders to stay longer in the auction, just to learn about the state of competition. Both effects boost revenues, and our analysis provides a rationale for using dynamic formats rather than sealed‐bid ones.     

Relaciones laborales y medidas de ajuste frente a la crisis. Análisis microestadístico comparativo de Francia y Gran Bretaña

En este estudio comparativo, los autores analizan los vínculos entre las relaciones laborales y los ajustes salariales o de plantilla tras la crisis de 2007–2008, a partir de dos encuestas comparables sobre empresas de Gran Bretaña (WERS) y de Francia (REPONSE) en 2010–2012. Pese a las diferencias contextuales (composición del tejido productivo, circunstancias temporales e intensidad de la crisis), los vínculos entre las relaciones laborales y las estrategias de ajuste son parecidos (la presencia sindical no logra evitar los ajustes). Por lo tanto, la diferenciación de los sistemas de relaciones laborales no permite explicar las divergencias entre las modalidades de ajuste a nivel macroeconómico.     

Size matters for OTC market makers: General results and dimensionality reduction techniques

In most over‐the‐counter (OTC) markets, a small number of market makers provide liquidity to other market participants. More precisely, for a list of assets, they set prices at which they agree to buy and sell. Market makers face therefore an interesting optimization problem: they need to choose bid and ask prices for making money while mitigating the risk associated with holding inventory in a volatile market. Many market‐making models have been proposed in the academic literature, most of them dealing with single‐asset market making whereas market makers are usually in charge of a long list of assets. The rare models tackling multiasset market making suffer however from the curse of dimensionality when it comes to the numerical approximation of the optimal quotes. The goal of this paper is to propose a dimensionality reduction technique to address multiasset market making by using a factor model. Moreover, we generalize existing market‐making models by the addition of an important feature: the existence of different transaction sizes and the possibility for the market makers in OTC markets to answer different prices to requests with different sizes.     

Modeling advertising impact at campaign level: Empirical generalizations relative to long-term advertising profit contribution and its antecedents

Research on advertising effectiveness is focused on sales and provides few empirical generalizations on profitability and its antecedents. To fill this gap, we develop an econometric model to capture the impact of advertising at campaign level, using retail panel data coupled with TV audience tracking data. Our study involves 31 brands from six packaged goods categories observed weekly and nationally over 4 years and representing 264 TV campaigns. Although we confirm empirical generalizations on the capacity of advertising to increase sales, we establish a different picture for profitability. Only 11 % of campaigns make a positive contribution to profit. Advertising is more profitable for challengers and medium brands, whereas leaders and small brands (recent or established) have a lower profitability. Advertising intensity in the category and campaign carry-over emerge as the strongest (respectively) negative and positive drivers of profitability. The antecedents of carry-over are also analyzed and discussed.
