What do Thirteen Million Price Records have to Say about Consumer Price Rigidity?*

Based on the analysis of 13 million price records underlying the computation of the French consumer price index, we provide a detailed assessment of consumer price rigidity. Our main results are as follows. The average duration of prices is around 8 months. Price durations and the patterns of price‐setting strongly differ across sectors. Price cuts are almost as frequent as increases, suggesting no specific downward nominal rigidity. Price changes typically have large absolute sizes. Time variation in the frequency of price changes and in their size both contribute to inflation fluctuations. Overall there is evidence of both time‐ and state‐dependent price‐setting.     

Incentive-Compatible Contracts for the Sale of Information

An informed financial institution can trade on private informationand also sell it to clients through a managed fund. To providean incentive for the informed agent to trade in the interestof her client, the optimal contract requires that she be compensatedas an increasing function of the profits of the fund. The optimalcontract is also designed to limit the aggressiveness of thesum of the fund's trade and the proprietary trade. This reducesinformation revelation and thus leads to greater overall tradingprofits than if the informed agent only conducted proprietarytrades.     

How to Forecast Long-Run Volatility: Regime Switching and the Estimation of Multifractal Processes

We propose a discrete-time stochastic volatility model in whichregime switching serves three purposes. First, changes in regimescapture low-frequency variations. Second, they specify intermediate-frequencydynamics usually assigned to smooth autoregressive transitions.Finally, high-frequency switches generate substantial outliers.Thus a single mechanism captures three features that are typicallyviewed as distinct in the literature. Maximum-likelihood estimationis developed and performs well in finite samples. Using exchangerates, we estimate a version of the process with four parametersand more than a thousand states. The multifractal outperformsGARCH, MS-GARCH, and FIGARCH in- and out-of-sample. Considerablegains in forecasting accuracy are obtained at horizons of 10to 50 days.     

Bank Competition and Collateral: Theory and Evidence

We investigate the impact of bank competition on the use of collateral in loan contracts. We analyze asymmetric information about the borrowers’ type in a Salop model in which banks choose between screening the borrower and asking for collateral. We show that the presence of collateral is more likely when bank competition is low. We then test this prediction empirically on a sample of bank loans from 70 countries. We perform logit regressions of the presence of collateral on bank competition, measured by the Lerner index. Our empirical tests corroborate the theoretical predictions that bank competition reduces the presence of collateral. These findings survive several robustness checks.     

Detecting Asymmetric Price Transmission with Consistent Threshold along the Fish Supply Chain

The present study deals with asymmetric price transmission (APT) along the fish value chain by using a consistent threshold autoregressive (consistent TAR and momentum‐threshold autoregressive [M‐TAR]) model. A nonzero threshold captures strategic behaviors and adjustment costs that are not observable with small price changes around a zero threshold. Fish farming, because of greater control over supply, is expected to produce less asymmetry than wild harvesting. Asymmetry is notwithstanding found for both wild cod and farmed salmon marketed in France, but only with consistent thresholds and operating in opposite ways. The results are discussed with regard to the trade restrictions imposed by the Common Fisheries Policy. Cet article traite de l’asymétrie de transmission des prix (ATP) dans la filière des produits de la mer en utilisant un modèle autorégressif à effet de seuil (consistent TAR et M‐TAR). Un seuil non nul permet de révéler certains comportements stratégiques et des coûts fixes d’ajustement qui ne seraient pas observables sur de faibles variations de prix autour d’un seuil nul. On s’attend à ce que l’aquaculture, en vertu d’un degré de contrôle supérieur sur l’offre, engendre une plus faible asymétrie comparativement à la production halieutique. Une asymétrie de transmission est néanmoins observée à la fois dans le cas du cabillaud sauvage et du saumon d’élevage commercialisés en France, mais uniquement à partir de seuils endogènes et l’ATP agissant en sens opposé. Les résultats sont commentés au regard des restrictions commerciales imposés par la Politique Commune des Pêches européenne.     

Who are Advisory Services Leaving Out? A Critical Reflection on ‘Hard to Reach’ Farmers

Although the Common Agricultural Policy of the European Union has broadened its objectives to integrate social issues, several hard-to-reach groups of farmers and workers continue to be ignored by advisory services and associated policies. Connecting with these groups has a strong potential to increase the economic and social cohesion of European agricultures. We interviewed over 1,000 farmers across Europe and identified features of these groups that are often overlooked by advisory services. We critically reflected on the social cohorts omitted from advisory services and how they could be better reached; they include farm labourers, new entrants or ‘career changers’, and later adopters. We clarify the different types of advisors in the advisory landscape, distinguishing between those who are linked to or independent from sales of inputs or technologies. We make concrete recommendations about how to engage advisors with hard-to-reach groups, with approaches suited to different national contexts of Agricultural Knowledge and Innovation Systems (AKIS); thus contributing to the ‘AKIS dimension of National Strategic Plans of the next Common Agricultural Policy, 2023–2027. We argue for the more effective use of advances in the social sciences through a better understanding of advice as social interaction which can bolster the inclusiveness of public policies.     

Changes in the marketing and operational capacity of retail sector firms through corporate securitization

Corporate securitization is a structured finance product that retail companies use to raise funds on the back of their operating assets. We investigate whether corporate securitization enhances the retail firm's marketing and operational capacity through a set of structural enhancements including operating covenants. Operating covenants are designed to mitigate the financial and operating risks of a securitized business and improve its marketing potential. Using the case of a retail firm's securitization, the United Kingdom's Mitchell's & Butler's, we find some support for this conjecture. We also find that corporate securitization is more successful where managers have considerable scope for making changes in the retail firm's operating and marketing environment.     

Predation in off-patent drug markets

In 2009, Sanofi-Aventis, whose generic subsidiary is Winthrop, merges with the generic firm, Zentiva. This article fills the gap in the theoretical literature concerning mergers in pharmaceutical markets. To prevent generic firms from increasing their market share, some brand-name firms produce generics themselves, called pseudo-generics. We develop a Cournot duopoly model by considering the pseudo-generics production as a mergers' catalyst. We show that a brand-name company always has an incentive to purchase its competitor. The key insight of this article is that the brand-name laboratory can increase its merger gain by producing pseudo-generics beforehand. In some cases, pseudo-generics would not otherwise be produced and this production is then a predatory strategy.
