Stock selection using a multi-factor model - empirical evidence from the French stock market

Using a Barra-type factor model, we have attempted to determine whether it is possible to beat the benchmark by taking advantage of anomalies established in the financial empirical literature. More specifically we have built an equity premium model based on three sets of factors (accounting variables, stock market characteristics and sector indicators) using a Bayesian method corrected for heteroscedasticity to estimate risk premiums, a technique that takes agents' learning into account. The results are encouraging: first, the factors that carried most weight on the equity premiums corroborated the results of empirical studies described in the financial literature, secondly, the portfolios constructed from our methodology and simulated outside our sample, returned higher performance than the benchmark and rewarded the supplement of volatility.     

Optimal taxation and welfare benefits with monitoring of job search

In order to investigate the interaction between tax policy, welfare benefits, the government technology for monitoring and sanctioning inadequate search, workfare, and externalities from work, we incorporate endogenous job search and involuntary unemployment into a model of optimal nonlinear income taxation. In this setting, the government faces a trade-off between boosting employment of low-skilled agents and raising work effort of high-skilled workers. If sanctions for inadequate search effort can be targeted at high productivity types for whom it is socially optimal to search, the government can afford to levy higher labor taxes on marginal workers without discouraging these agents from seeking work. This allows for lower marginal taxes on work effort of agents with a job. In contrast to workfare, job externalities in the private sector raise marginal tax rates, as the government attaches more importance to boosting employment of low-skilled workers.     

Bringing Unemployed Back to Work: Effective Active Labor Market Policies

We present a theoretical analysis of different types of active labor market policies in the context of a search-matching model. We find that labor market training is effective in bringing down unemployment while public employment services and subsidized jobs are not effective at all. This theoretical finding is confirmed in an explorative empirical analysis using data from 20 OECD countries.     

Fish as the “bank in the water” – Evidence from chronic-poor communities in Congo

Small-scale fisheries in developing countries are often perceived as being a low-productivity and backward informal sector. As a result they are rarely considered in poverty reduction programmes and rural development planning. In this paper, we investigate the dual role of fish as a food and cash crop through data collected in river fisheries in Democratic Republic of Congo (DRC). Fishing in this very remote rural region of DRC is operated both by men and women, as part of a household multiple activity livelihood strategy. The data shows that poor households rely heavily on fishing for their supply of protein-rich food, in particular through women’s subsistence catches. Fishing also appears to be the main source of cash-income for the majority of households, including local farmers. Based on these findings and a review of the literature, the paper argues that small-scale fisheries can play a fundamental role in local economies, especially in remote rural areas where they strengthen significantly the livelihoods of people through their role in both food security and cash-income generation.     

Do Termination Provisions Truncate the Takeover Bidding Process?

We provide new evidence on termination provisions and the takeoverbidding process. Our central contribution is a novel databasefrom Securities and Exchange Commission (SEC) documents thataccurately measures the incidence of termination provisionsand the depth of competition in takeover deals. We show thatbiased data in prior research produced incorrect conclusionson the relation between termination provisions and judicialdecisions, bidder toeholds, and deal size. Our comprehensivedata also show that termination provisions are positively relatedto takeover competition. Our evidence is consistent with theinformation/commitment hypothesis in which termination provisionsdo not truncate bidding but instead culminate the takeover process.(JEL G34; K22; D44).     

Social media adoption: A process-based approach

This research conceptualizes and measures social media adoption (SMA) of companies with a process-based approach and explains its antecedents of micro- and macro-environment, size, and ownership, as well as its consequence of intention to increase resources dedicated to social media. Based on data from 310 Turkish small and medium enterprises, the study first develops a conceptual framework on the pillars of internal and external stakeholder focus as well as relationship and information oriented implementation. Based on these two dimensions, it discusses the novel concepts of social customer relations, social stakeholder communication, social intelligence, and social responsiveness related to SMA. The study further indicates that ownership type and micro environment play a role in SMA and that path dependence exists in the interplay of current adoption and future intentions.     

Billboard and cinema advertising: Missed opportunity or spoiled arms?

Advertising remains one of the most popular marketing instruments, and many studies have studied its sales effectiveness. However, prior research has either looked at the total spending of a brand/firm, or has focused on the most popular media, especially TV advertising. Even though huge amounts are also spent on “smaller” media such as billboards and cinema, little is known on their effectiveness.
