Distributional implications of a shorter working week: An unpleasant note

Do “proletarians” gain from work sharing? In a labor-market model with wage rigidity and endogenous labor supply, it is shown that a reduction of the workweek may decrease the expected utility of the poor and increase the expected utility of the rich.     

Models of Capital Requirements in Static and Dynamic Settings

The aim of this paper is twofold. First, we generalize the notion of capital requirement, originally formulated in a regulatory framework, in order to unify other apparently diverse financial concepts. Second, we stress the interpretation of a capital requirement as a measure of risk, providing a link with the theory of coherent risk measures. We define a capital requirement as the minimal initial cost of a hedging action that makes the original position acceptable. Three basic elements are involved in such a methodology: a system of prices, a class of permitted hedging actions and a criterion of acceptability. Our approach is very general, because we construct capital requirements on vector spaces. However, we will give some concrete applications related, in particular, to the availability of a financial market, to the presence of different business units in an institution or to the fact that pay-offs are spread over different dates.     

Does the perception of incongruence hurt more? Customers’ responses to CSR crises affecting the main reputation dimension of a company

ABSTRACT

Corporate social responsibility (CSR) generates benefits for companies and society. However, CSR exposes a company to potential damage when a critical event, such as a crisis, disconfirms the CSR of a corporate reputation. The present article introduces to the crisis management literature the notion of consumer-perceived incongruence (CPI) between corporate reputation and crises. Our first experimental study demonstrates that a high CPI – compared to a low CPI – worsens consumer responses in terms of attitude towards the corporation (ATC), word of mouth (WOM) and purchase intention (PI). The second study shows that these effects are mediated by the perception of a state of discomfort on the part of the consumer. The third study suggests that, in cases of high CPI, the corporate crisis response strategy of apology outperforms that of compensation in reducing the negative effects of discomfort on consumer responses. Theoretical and managerial implications are discussed.     

Incentive Regulation of Multinational Enterprises*

Sectors with a long regulatory tradition have recently experienced intense activity by multinationals whose international operations and relocation threats represent a new cause for concern for regulators. I analyze a multinational serving two countries and being regulated by two national authorities. The firm is shown to favor, or cross‐subsidize, the country with a larger stake in the firm's profit, and the linkage among national regulations may induce unexpected effects on outputs. I also analyze a multinational's lobbying decisions and its effects on national regulations. Finally, a credible threat to “fly” away from tough regulators lets the firm obtain larger profits.     

Limited knowledge of demand and oligopoly equilibria

In a standard model of oligopoly with differentiated products, the existence of an equilibrium at which the first-order conditions for profit maximisation are simultaneously satisfied for all firms is proved and this is done without imposing any restrictions on the demand functions. This is an equilibrium in the following sense: although some firms may not necessarily be maximising their profits, nevertheless if each firm's knowledge of demand is limited to the linear approximation of its own demand curve, then it will believe that it is indeed maximising its profits.     

Impact of multiple curve dynamics in credit valuation adjustments under collateralization

We present a detailed analysis of interest rate derivatives valuation under credit risk and collateral modeling. We show how the credit and collateral extended valuation framework presented in Pallavicini et al. [Funding valuation adjustment: FVA consistent with CVA, DVA, WWR, collateral, netting and re-hyphotecation, 2011], and the related collateralized valuation measure, can be helpful in defining the key market rates underlying the multiple interest rate curves that characterize current interest rate markets. A key point is that spot Libor rates are to be treated as market primitives rather than being defined by no-arbitrage relationships. We formulate a consistent realistic dynamics for the different rates emerging from our analysis and compare the resulting model performances to simpler models used in the industry. We include the often neglected margin period of risk, showing how this feature may increase the impact of different rates dynamics on valuation. We point out limitations of multiple curve models with deterministic basis considering valuation of particularly sensitive products such as basis swaps. We stress that a proper wrong way risk analysis for such products requires a model with a stochastic basis and we show numerical results confirming this fact.     

Evaluation of land-use and transport network effects on cyclists' route choices in the Copenhagen Region in value-of-distance space

Growing interest in sustainable transportation systems has driven decision-makers toward policies and investments aimed at promoting cycling, but little to no effort has been made toward incorporating bicycle transport in transport planning models. This study contributes toward this direction by estimating a bicycle route choice model in value-of-distance space from a large sample of 3384 cycling trips that were traced with GPS devices in the Copenhagen Region. The novelty of this study lies in (i) observing cyclists' behavior in a cycling-oriented country, (ii) exploiting rich data about the cycling environment, (iii) estimating the model in value-of-distance rather than preference space, and (iv) not focusing only on preferences for traditional variables (e.g., distance, turns, hilliness, intersections, motorized road characteristics), but also on perceptions and preferences for bicycle facilities (e.g., bicycle lanes, bicycle paths, bicycle traces) and land-use designations (e.g., residential, industrial, sports, scenic areas). The findings from the model show that: (i) cyclists exhibit heterogeneous preferences for avoiding right and left turns, cycling the wrong way, using roundabouts and bridges, and cycling alongside residential and scenic areas; (ii) cyclists dislike cycling on unpaved and hilly surfaces and alongside larger roads; (iii) cyclists have clear perceptions about different types of bicycle facilities, with a preference for bicycle lanes and segregated paths; (iv) cyclists have clear perceptions about land-use designations, with a preference for cycling alongside sports and scenic areas; (v) time-of-day and air temperature contribute to the perceptions of cyclists and their preferences for bicycle facilities and land-use designations.
