Local stakeholders’ perception of muddy flood risk and implications for management approaches: A case study in Alsace (France)

The inventory of muddy floods in France indicates that the occurrence of these events seriously increased in the North West and the East of the country. Muddy floods triggering can largely be explained by physical characteristics such as a hilly topography, soils prone to crust, and/or heavy rainfall in spring. Although the physical processes are well known by now and despite increasing information about the need of mitigation measures, no significant reduction of these disasters has been registered. Therefore, this should be explained by factors others than scientific reasons or technical knowledge acquisition difficulties.     

Labour market transitions and unemployment duration: Evidence from Bulgarian and Polish micro-data1

The segmentation of the labour market is one of the most striking characteristics of the transition process in Central and Eastern European countries. Not only do the young, unskilled workers and women face a high risk of unemployment, but joblessness also varies significantly geographically. This paper sheds some light on labour market segmentation in transition countries by analysing individual records of individuals registered at the labour offices of two Polish regions (Warsaw and Ciechanov and two Bulgarian regions (Sofia and Botevgrad) over the initial three to four years of the transition to a market economy. The empirical results confirm the existence of highly selective firing and hiring processes in the Polish and Bulgarian labour markets. Overall, unskilled or poorly educated workers have the highest probability of becoming unemployed and remaining without a job for a long period of time. We also analysed the determinants of unemployment duration across regions and over time using a piece-wise constant hazard model with multiple destinations, i.e. employment and exit from the labour force. The results suggest that the unemployed with a high education and previous experience in the private sector have a higher probability of getting a new job, especially in the more dynamic labour markets, while those without previous work experience tend to stay unemployed for a longer period of time and often leave the labour market. The econometric results also suggest that the reforms of the unemployment benefit systems have produced important effects on unemployment flows.     

The Design of Optimal Insurance Contracts: A Topological Approach

This article deals with the optimal design of insurance contracts when the insurer faces administrative costs. If the literature provides many analyses of risk sharing with such costs, it is often assumed that these costs are linear. Furthermore, mathematical tools or initial conditions differ from one paper to another. We propose here a unified framework in which the problem is presented and solved as an infinite dimensional optimization program on a functional vector space equipped with an original norm. This general approach leads to the optimality of contracts lying on the frontier of the indemnity functions set. This frontier includes, in particular, contracts with a deductible, with total insurance and the null vector. Hence, we unify the existing results and point out some extensions.     

Towards a better understanding of mobile banking: the impact of customer experience on trust and commitment

In the current context of ubiquitous connectedness through portable mobile devices and services, it is important to comprehend more fully the nature of consumer/bank interactions and relationships. At the same time, firms in the service sector are trying to provide customers with impactful positive experiences. This article examines the impact of mobile banking experience on trust and commitment based on the customer experience dimensions defined by Schmitt and expanded to include the negative aspect of the affective dimension. A total of 396 panellists of a recognized Canadian research firm responded to a self-administered online questionnaire. Findings demonstrate that the cognitive and negative affective dimensions of mobile experience impact trust, whereas the positive affective/sensory dimension influences commitment. The behavioural and social dimensions do not have significant impacts. This study enriches the theoretical corpus of knowledge in customer experience, relationship marketing and m-banking literature, lending practical implications for mobile services managers. Financial institutions, for example, should offer sensory mobile applications designed to appeal to the eye or to the touch (positive affective/sensory dimension), provide tools and information intended to arouse user curiosity and provoke reflection (cognitive dimension), while avoiding negative experiences which can lead to damaging feelings/emotions such as disappointment and anger (negative affective dimension).     

Taxes and subsidies to change eating habits when information is not enough: an application to fish consumption

A calibrated model is used to determine the welfare impacts of various regulatory instruments for improving health. The results of a lab experiment are integrated in a partial equilibrium model representing demands for two kinds of fish, one with higher nutritional benefits (canned sardines) and one with higher contamination risks (canned tuna) in France. In the laboratory, information about health effects leads to a statistically significant decrease (increase) in the willingness to pay for tuna (sardines). Simulations with the laboratory results show that, for most cases, a per-unit tax on tuna and a per-unit subsidy on sardines without any information revealed to consumers lead to the highest welfare, because both the tax and subsidy directly internalize health characteristics. The information policy combined with a per-unit tax on tuna and a per-unit subsidy on sardines is socially profitable only if a large proportion of consumers (greater than 95%) receives health information.      

Tax policies and agency costs

We show that when large corporations are subject to a different tax system than smaller firms, the agency cost of under- and overinvestment is significantly altered. In contrast to the findings in the literature, the gap between the first- and second-best investment trigger prices do not move in lockstep with variations in the corporate tax rate, as in the case of a linear tax system. We show that the gap can either widen or shrink, depending on the tax policy design and regime. In addition, we find that the agency cost under a progressive tax regime is considerably larger than the agency cost under a regressive tax regime when equityholders have to bear all the investment costs. These results are reversed when managers have the ability to issue additional debt to finance the firm's expansion and transfer part of the investment costs to bondholders.
