Foreign Aid and the Business Cycle

This paper documents empirical regularities in the foreign aid flows to developing countries over three decades. In spite of a large body of literature on foreign aid and its impact on recipients, surprisingly little is known about its business cycle characteristics. The authors show that for the vast majority of African recipients, aid flows are a major source of income that is highly volatile and, most importantly, overwhelmingly procyclical. For recipients outside of Africa, there is a similar—if somewhat less pronounced—pattern of aid procyclicality. In contrast, there is little evidence of aid procyclicality with the business cycle of donors. In light of the very high volatility of output in developing countries, the procyclicality of foreign aid flows from the recipients' perspective raises serious questions related to their welfare and growth.     

Strategic nonlinear pricing

The objective of this paper is to examine the role of nonlinear strategies in a standard oligopoly framework. We demonstrate that nonlinear pricing may indeed emerge as an equilibrium strategy, but only when firms produce differentiated products, when one firm retains market power due to a cost advantage, or as part of an equilibrium in mixed strategies. In addition, we examine the role of nonlinear pricing in a spatial-competition framework. Our main conclusion is that in highly competitive markets, nonlinear pricing strategies are not likely to emerge as an equilibrium.     

Aggregate Fluctuations and International Migration

In this paper, we study the role of short‐run factors such as business cycles or changes in employment rates in explaining international migration flows. First, we derive a model of optimal migration choice predicting that short‐run economic fluctuations trigger migration flows on top of the impact exerted by long‐run factors. Second, we empirically test the magnitude of the effect of these short‐run factors on migration flows. Our results indicate that both aggregate fluctuations and employment rates affect migration flows. Third, we provide evidence that the Schengen Agreement and the euro significantly increased the international mobility of workers between the member countries.uuuü

Existence,uniqueness, and stability of optimal payoffs of eligible assets

In a capital adequacy framework, risk measures are used to determine the minimal amount of capital that a financial institution has to raise and invest in a portfolio of prespecified eligible assets in order to pass a given capital adequacy test. From a capital efficiency perspective, it is important to be able to do so at the lowest possible cost and to identify the corresponding portfolios, or, equivalently, their payoffs. We study the existence and uniqueness of such optimal payoffs as well as their behavior under a perturbation or an approximation of the underlying capital position. This behavior is naturally linked to the continuity properties of the set‐valued map that associates to each capital position the corresponding set of optimal eligible payoffs. Upper continuity can be ensured under fairly natural assumptions. Lower continuity is typically less easy to establish. While it is always satisfied in a polyhedral setting, it generally fails otherwise, even when the reference risk measure is convex. However, lower continuity can often be established for eligible payoffs that are close to being optimal. Besides capital adequacy, our results have a variety of natural applications to pricing, hedging, and capital allocation problems.     

Impact of responsive and proactive market orientation on SME performance: The moderating role of economic crisis perception

This study examines the relationship between market orientation (MO) and the performance of small and medium‐sized enterprises (SMEs) within the context of economic crisis. It distinguishes between two levels of MO: responsive market orientation (RMO) and proactive market orientation (PMO). Data were collected on a sample of 300 SME. Findings indicate that SMEs, confronted with an economic downturn, use a MO approach that is both proactive and responsive, and reveal the moderator effect of the SME manager's perception of an economic crisis on PMO/RMO–performance. Research and practical implications are discussed. © 2018 ASAC. Published by John Wiley & Sons, Ltd.     

On financial guarantee insurance under stochastic interest rates

We extend the financial guarantee insurance literature by modeling, under stochastic interest rates, private financial guarantees when the guarantor potentially defaults. By performing numerical simulations under plausible parameters values, we characterize the differential impact of the incorporation of stochasticity of interest rates on the valuation of both public and private guarantees.     

Regulation of working time in SMEs of the information and communication technology sector in France

This paper focuses on the impact of the French working-time reduction law on small and medium enterprises (SMEs) in the information and communication technology sector. After a presentation of the main features of this sector, made up of a wide range of SMEs, the paper aims at describing how the actors have negotiated the application of the new legal framework at sector and company levels. The new working-time regulation outlines the status of high-skilled employees (cadres) as a very important conflict and negotiation subject.
