The resulting optimal control problem has two inter-related state variables: the stock of pollution and the absorption capacity of the environment. The stock of pollution decreases with environmental absorption capacity and increases with the rate of current emissions, which is controlled by a production level as well as an emissions reduction effort. However, the environmental absorption capacity is positively affected by an absorption development effort, and negatively impacted by the stock of pollution. Under specific conditions, it is shown that an optimal path, which can be either monotonic or following transient oscillations, leads to a (nontrivial) saddle-point characterized by a positive environmental absorption capacity."

We assume that production experience is affected by random causes, and that the learning process may involve spillovers of experience from the competing firm. As in the Cournot competition, in this differential game the firms compete by choosing the quantities of products that they will produce. In contrast to the Cournot assumption, according to which firms maximize their profits by taking as given the quantity produced by the competitor, we assume that a firm may not be able to determine its competitor’s reaction to a change in its output and instead may conjecture the competitor’s response. We find that, in contrast to the case of a steady state, an open-loop equilibrium over a finite planning horizon may result in greater output (more competitive behavior) compared with a subgame-perfect equilibrium. We show that this result is due to the fact that strategic behavior in feedback Nash equilibrium depends on the relationship between the level of proprietary learning by doing (which encourages strategic complementarity) and the level of spillovers (which involves strategic substitutability)."

This research investigates the impact of both horizontal and vertical competition, on the one hand, and strategy types (commitment-based versus contingent-based equilibrium strategies), on the other hand, on the pollution accumulated by two supply chains over time. We consider a two-stage game model where two manufacturers and two retailers are involved in a wholesale price contract, in order to supply the demand over a finite time horizon. In the first stage of the game, the manufacturers set their respective optimal transfer prices. During the second stage, polluting emissions are created over time in proportion with demand, which is controlled by the retailers’ respective consumer prices. In this stage, the manufacturers are involved in emissions abatement. In this setup, we seek to identify the combination of market structure and strategy type that leads the two supply chains to generate the lowest pollution intensity and the highest level of abatement intensity.\n

In order to assess the impact of both learning and forgetting on longterm competitiveness and a firm’s profitability, we model an experience accumulation process with depreciation and consider two competing firms that produce fully substitutable products. In this model, unit production costs decrease with the firm’s experience due to the proprietary learning process as well as the spillover of experience from the competing firm. Firms can either share or hide from each other their information about the state of their respective experience throughout the game. We found that in an equilibrium steady state, if the organizational forgetting is sufficiently large (larger than the spillover rate value), then information sharing, compared to information hiding, results both in less competitiveness and increased profits for firms. Conversely, if the organizational forgetting is small and the spillover opportunities are relatively large, then information sharing promotes both long term competitiveness and firm profits. Accordingly, firms are better off in the long term by deliberately limiting (expanding) their experience accumulation process whenever organizational forgetting is relatively large (small). A high ability of proprietary learning, however, can interfere in this relationship so that limiting the firms’ experience process will always be compatible with higher profitability."

Pour spécifier la dynamique des ventes instantanées, nous supposons que le prix est un signal fiable de qualité et que la demande exprime une préférence pour la qualité par rapport au prix. La réolution du programme dynamique par le principe du maximum de Pontryagin débouche sur des cas de figures différenciés. D'autre, part, une validation empirique des hypothèses du modèle des ventes de terminaux téléphoniques nous permet d'améliorer très sensiblement le coefficient de détermination obtenu par le modèle de Bass. Enfin, une application numérique du problème du contrôle optimal de la diffusion par la qualité permet de mesurer le coût d'opportunité de la stratégie optimale de qualité par rapport à la stratégie observée."

To do so, we introduce a dynamic demand function leaning on two hypotheses : first, price acts as a signal to quality , second, demand is more sensitive to quality than to price. Using the maximum principle of Pontryagin, we then characterize the optimal dynamic trajectory of quality and its qualitative properties."

"fr" => "Cet article résout un problème de diffusion de produit par sa qualité, utilisant le contrôle optimal dans un contexte de compétition monopolistique. Pour cela, nous introduisons une fonction de demande dynamique reposant sur deux hypothèses. Dans une première, le prix agit comme signal de la qualité. Dans une deuxième, la demande est plus sensible à la qualité qu'au prix. On utilise finalement le Principe de Pontryagin afin de déterminer les trajectoires optimales de la qualité et ses propriétés."
"en" => "In this paper, we solve the problem of optimal control of quality-driven product diffusion in a context of monopolistic competition. To do so, we introduce a dynamic demand function leaning on two hypotheses : first, price acts as a signal of quality, second, demand is more sensitive to quality than to price. Using the maximum principle of Pontryagin, we then characterize the optimal dynamic trajectory of quality and its qualitative properties."

Une extension du modèle de Lanchester est proposée dans laquelle la qualité (au sens de conformité) et la réputation sont les principaux leviers de concurrence pour le développement de la part de marché. Le taux d'attraction de nouveaux consommateurs par un concurrent dépend de sa réputation tandis que le taux d'abandon des consommateurs effectifs est déterminé par le pourcentage de produits non conformes. La recherche d'une solution non-coopérative par des méthodes qualitatives et numériques conduisent à définir la stratégie optimale des efforts publicitaire et d'amélioration de la qualité pour chaque concurrent à travers un large éventail de configurations."
"en" => "This paper analyzes optimal advertising and quality improvement decisions by duopolist firms competing in a dynamic setting. An extended version of the Lanchester model is formulated where conformance quality and goodwill are both involved in competition for market share. Each competitor’s new customer attraction rate depends on its own goodwill, while the disloyalty rate for current customers is influenced by the proportion of defective items. The search for a non-cooperative solution by qualitative as well as numerical means leads to definition of the optimal path for advertising and improvement efforts for each competitor, examined under a wide range of configurations."

However, as in other parts of supply chain management, decentralized decision-making in supply quality management is prevalent, which causes inefficiencies such as the well-known double marginalization phenomenon. Coordinating schemes, such as the revenue sharing contract, can contribute to mitigating this phenomenon. In this paper, we investigate the potential coordinating power of the revenue sharing contract in a supply chain with one manufacturer and one supplier that collaborate to improve the design quality of a particular finished product. We set the cooperative outcome as a benchmark and compare the efficiency of an optimal revenue sharing contract with an optimal wholesale price contract in improving design quality in the setup of a non-cooperative two-stage game."

The behavior of the best performer in the team differs on whether he can impose a sanction on the less performing partner. When sanctions are not allowed, good performers reduce their effort in response to the advantageous difference in scores; when they can impose sanctions, their change in effort is no longer related to the difference in scores. To some extent, a sanction mechanism allows good performers to focus on their own performance. In the case of costless sanctions, not sanctioning a partner who under-performs, what we refer to as forgiveness, prompts the latter to improve his performance, but applying the sanction has a stronger push effect."

"fr" => "In this paper, an extension of the Bass model is suggested that accounts for the influence of conformance quality on mixed (i.e., positive and negative) word-of-mouth in the diffusion of a new product. A primary goal is to determine how an active operational policy seeking to continuously improve conformance quality affects the optimal leveraging of marketing instruments used to diffuse new products, and the resulting sales and profits. To do so, an optimal tradeoff by a monopolistic firm between advertising effort and price, on the one hand, and conformance quality, on the other hand, is analyzed, along with the implications for word of mouth effectiveness. Our results can be summarized as follows. Price and advertising levels are respectively lower and higher under an operations–marketing policy than under a marketing policy only. As a result, themarket potential and the innovation effect are higher under an operations–marketing policy than under a marketing policy only, as is the imitation effect due to conformance quality improvements over time. Also, greater cumulative sales and cumulative profits are obtained. However, higher design quality results in a lower price and greater advertising effort under an operations–marketing policy than under a marketing policy only. Finally, for lower design quality, the two policies result in different patterns (non-monotonic vs. monotonic) for price and advertising yet cumulative sales and profits are of quite similar magnitude."

We address quality improvement in a competitive duopoly market for partially substitutable products characterized by levels of quality that are not necessarily identical. The products’ quality is described with a hazard rate that can be improved both by accumulating production experience (autonomous learning) and quality improvement efforts (induced learning). Given that defective items are fully reimbursable and the demands exhibit increasing returns to scale, we derive Nash equilibrium pricing and induced learning effort dynamic policies. We show that when the effectiveness of autonomous learning prevails over the effectiveness of efforts in induced learning, equilibrium prices gradually grow over time; the trend is quite the opposite when autonomous learning is less effective than induced learning."

Depending on whether a given product or service is a good or a bad deal, this can significantly contribute to commercial success or failure. Yet the existing dynamic models of sales in marketing still assume that the influence of word of mouth on sales is at best advertising-dependent. This omission can produce ineffective management and therefore misleading marketing policies. This paper seeks to bridge the gap by introducing a contagion sales model of a monopolist firm's product where sales are affected by advertising-dependent as well as autonomous word of mouth. We assume that the firm's attraction rate of new customers is determined by the degree at which the current sales price is advantageous or not compared with the current customers’ reservation price. A primary goal of the paper is to determine the optimal sales price and advertising effort. We show that, despite costly price adjustments, the interactions between sales price, advertising-dependent and autonomous word of mouth can result in complex dynamic pricing policies involving history-dependence or limit cycling consisting of alternating attraction of new customers and attrition of current customers."

To promote customer demand while seemingly complying with regulations, manufacturers may cheat even at the risk of incurring severe penalties. As a result, the production horizon becomes uncertain. Assuming it is socially critical to enforce quality standards (e.g., specific emission levels or safety levels for food, drugs, or transportation), we study dynamic production policies under the threat of penalties and assess when a false quality claim can be optimal for the firm. We find that regardless of the specific form of a convex penalty function, the production rate will gradually decrease to slow down the increase in the probability of getting caught. We show that the government or regulatory department can determine a minimal finite penalty to prevent the manufacturer from cheating. In the context of an underlying supply chain, we show that vertical competition between the manufacturer and its suppliers can play a socially positive role by reducing the batch produced under a false quality claim."

This article seeks to bridge the gap by introducing a dynamic model of pollution accumulation where polluting emissions can be mitigated and the absorption efficiency of pollution sinks can be restored. We assume that emissions are due to a production activity, and we include deforestation both as an additional source of emissions and as a cause of the exhaustion of environmental absorption efficiency. To account for the fact that the switching of natural sinks to a pollution source can be either possible, and in such a case even reversible, or impossible, we consider that restoration efforts can be either independent from or dependent on environmental absorption efficiency, i.e., state-independent versus state-dependent restoration efforts. We determine (i) whether production or deforestation is the most detrimental from environmental and social welfare perspectives, and (ii) how state-dependent restoration process affects pollution accumulation and deforestation policies and the related environmental and social welfare consequences."

"en" => "Humans often lie strategically. We study this problem in an ultimatum game involving informed proposers and uninformed responders, where the former can send an unverifiable statement about the endowment received at the outset of the game. If there are some intrinsically honest proposers, a simple message game shows that the rest of them are likely to declare a lower-than-actual endowment to the responders, simply in order to reduce their expected endowment and be able to submit smaller offers. In the second part of the paper, we report on an experiment testing this game. On average, 88.5% of the proposers understate the actual endowment by 19%. Regression analysis shows that a one-dollar gap between the actual and declared amounts prompts proposers to reduce their offer by 19 cents. However, responders appear not to take such claims seriously, and thus the frequency of rejections increases. The consequence is a net welfare loss, that is specific to such a "free-to-lie" environment."

Un algorithme numérique de résolution de jeux différentiels à variables de contrôle indépendantes est présenté afin de résoudre efficacement les valeurs optimales de l'effort publicitaire, de la qualité et du prix dans le temps. En ce sens, la résolution numérique des modèles proposés révèle des stratégies contrastées à la foi au sein du duopole et entre le monopole et le duopole."

The analysis of the proposed model in the monopoly and the duopoly contexts respectively provides qualitative results for the optimal price, advertising and quality mix. A numerical algorithm for the resolution of differential games involving interdependent control variables is introduced to efficiently solve the optimal advertising, quality and pricing values over time. In particular, the comparative numerical study reveals contrasting strategies within and between the duopoly and the monopoly market structures."

Les équipes sont composées de deux joueurs. A chaque tour, le joueur qui fait le meilleur score peut appliquer une sanction à l'autre. Nous étudions les stratégies et les comportements des deux joueurs, dans une interaction qui dure quatre tours."
"en" => "This paper reports the results from a real-effort team production experiment, where best performers can impose either tacit or explicit sanctions on their less-performing partners. The behavior of the best performer in the team differs from one condition to another. When explicit sanctions are not allowed, good performers reduce their effort in response to the advantageous difference in scores; when they can impose sanctions, their change in effort is no longer related to the difference in scores. To some extent, a mechanism of explicit sanctions allows good performers to focus on their own performance. Not sanctioning an opponent who under-performs, what we refer to as forgiveness, prompts the latter to improve his performance, but applying the sanction has a stronger effect."

Dans un second temps, les extensions reposant sur des combinaisons appariées de ces modèles génériques sont analysées. L'apport méthodologique des jeux différentiels dans le cadre de la formulation des stratégies publicitaires concurrentielles est ainsi mis en évidence."

In the second part, extensions using a combination of these generic models are developed.

D'autre part, il montre que les déterminants de la délocalisation présentent un caractère d'invariance temporelle et que les modalités de la croissance à l'étranger s'inscrivent dans un contexte marqué par la spécialisation et des comportements concurrentiels hors-marché. Enfin, il examine le cadre institutionnel de la multinationalisation des firmes françaises et suggére la nécessité d'un engagement des pouvoirs publics aux côtés de ces dernières."

It describes the evolution of French assets abroad and its impact on the balance of trade. The paper shows that the determinants of delocation are temporally invariant and that multinationalization is characterized by a specialization process, and market independent competitive behaviors. Finally, the institutional context of French firms is examined. For long-term competitiveness, multinationals need to have their governments as partners rather than as regulators."

Un algorithme numérique permet de déterminer l'équilibre de Nash de chaque compétiteur en termes d'effort publicitaire et d'effort d'amélioration de la qualité à partir de diverses configurations initiales. En outre, une analyse de sensibilité conduit à identifier les facteurs-clé de la performance concurrentielle."

Moreover, a study of key-factors of performance points out the most appropriate reengineering projects to be implemented by a small inefficient firm in order to better its competitive position."

The firms are able to reduce their marginal production costs by accumulating their own experience as well as the experience spillovers from other firms. In particular, firms accumulate production experience through proprietary learning, which, however, depreciates over time. We determine steady-state Nash equilibrium policies that are based on the assumption that the firms do not have precise information about each competitor and therefore are unable to respond to a specific firm’s dynamics. The firms, however, do react to overall industry trends. We show that in such a case, though the information used for production control is incomplete, in the long run the firms tend to the output they would converge to under complete information. We also find that industry growth due to more firms entering the market results in decreasing long-run equilibrium output of each firm when the depreciation of experience is higher than the rate of spillovers. Otherwise, the opposite result can emerge, i.e., the steady-state output will grow."

This paper seeks to fill that gap by proposing to evaluate how certain specific behavioral patterns, namely propensity to forgiveness and propensity to attachment, can give rise to different collaborative archetypes. These two behavioral patterns are important as both are prominent in the most influential game theory and managerial approaches to cooperation. They are therefore used to derive a typology of behavioral profiles. Computation of each profile’s equilibrium effort leads to a ranking of the possible player profiles. The results suggest that the proposed behavioral profiles could be used for selection of potential partners."

Notamment, les stratégies publicitaires concurrentielles sont analysées en contexte de duopole à partir de modèles dynamiques des ventes en temps continu. Dans un premier temps, les stratégies publicitaires respectivement associées aux modèles d'effort publicitaire excédentaire, de Vidale-Wolfe et de Lanchester sont étudiées. Dans un second temps, les extensions reposant sur des combinaisons appariées de ces modèles génériques sont analysées. L'apport méthodologique des jeux différentiels dans le cadre de la formulation des stratégies publicitaires concurrentielles est ainsi mis en évidence."

Using sales dynamics models in continuous time, we analyze competitive advertising strategies in the duopoly context. First, advertising strategies derived from excess advertising model, Vidale-Wolfe model and Lanchester model are studied. Then, extensions obtained from combinations of these models are exposed. This survey emphasizes how differential games models are potentially useful to formulate optimal strategies in advertising competition."

Prior research on inventory control has been wide ranging, yet the environmental implications of an (s,S) inventory policy remain uninvestigated. This paper seeks to bridge the gap by characterising a firm’s voluntary environmental policy in the setup of an (s,S)\n
inventory control policy. We suggest a mixed model structure wherein, due to the presence of fixed production costs, the inventory is determined continuously by sales and impulsively with ordering decisions obeying an optimal stopping process, while the uncertain sales process is controlled by continuous-time environmental goodwill-related decisions. We show that a firm should successively use voluntary environmental efforts to stimulate its sales when there is inventory and to increase backlogging to improve its production efficiency. Given the recurrent pattern of this policy, we conclude that voluntary environmental efforts under an (s,S) inventory control is not compatible with using these efforts as a means to generate ephemeral reputation insurance.

"fr" => "The COVID-19 virus continues to circulate in many countries, despite successful attempts to curb previous waves, and hence the issue of effective control both of the epidemic and its economic consequences remains a matter of lively debate. Although the estimated development time for an effective vaccine proved to be relatively accurate, many governments were still unable to devise a clear and coherent control policy during the pre-vaccination period. Policy responses often vacillated between two seemingly conflicting strategies—protecting the economy versus containing the spread of the epidemic by all available means, including mobility restrictions and social and economic lockdown. In the setup of a multidimensional and non-linear optimal control model, we describe the performance of a capital accumulation-based economy in which the revenue generated from production relies on both capital and labor. Using analytical means, we characterize intertemporal policies that ensure an optimal tradeoff between: (i) the level of lockdown, the purpose of which is to contain the epidemic and prevent the national health system from becoming overwhelmed; (ii) the level of investment in treatments; (iii) the level of consumption; and (iv) consequential impacts on labor availability and capital accumulation. We show that the fear of infection alone can be highly capital-destructive. Finally, given an incompressible consumption level, we identify thresholds for the initial endowment in capital below which the stock of capital decreases over time and can eventually become fully depleted."

"fr" => "The waning efficiency of natural pollution sinks and the predicted consequence of their irreversible transformation into pollution sources within the current century call into question the environmental sustainability of economic activity and, more specifically, its basic engine: horizontal competition. Among factors likely to cast doubt on the environmental sustainability of competition, competing firms’ approaches to pollution control deserve particular attention because myopic approaches that ignore pollution dynamics accelerate such transformations. Another potentially harmful factor is the cost of adjusting production, which can hinder firms’ ability to reduce their polluting emissions in a timely way. In the context of a Cournot market structure, we consider competing firms that incur a cost when adjusting production and are subject to pollution emission taxes. We analyze how production adjustment costs and firms’ choice of myopic or farsighted pollution control policies affect their competitiveness and the long-run sustainability of the environmental system. We show that competition is not compatible with environmental sustainability under a myopic pollution control policy when the maximum threshold of pollution absorption has already been exceeded. Myopic policies cannot neutralize history dependency, and extremely large production adjustment costs exacerbate the problem. In contrast, farsighted pollution control policies can eliminate history-dependency as long as the tax policy is not too restrictive, though they lead to a more polluted environment than myopic policies operating below the maximum absorption efficiency threshold."

The book features contributions that address both environmental economics and environmental management. It presents a novel dynamic modeling framework for environmental economics in which environmental absorption efficiency is considered as a time-dependent variable with its own dynamics. It also introduces several extensions and applications of the model, including the possibility of including self-regenerating environmental absorption efficiency, non-cooperative transboundary issues with two superimposed free-rider behaviors (i.e., emissions reduction and restoration efforts), and deforestation. In the environmental management context, it puts forward an entirely new dynamic modeling framework. Unlike static approaches, the model considers both flow and stock variables, reflecting the accumulation of pollution over time. In turn, the book assesses sustainable configurations for supply chain competition, providing mathematical insights and managerial recommendations that integrate accumulated pollution aspects and associated negative externalities. Overall, the book calls for combining environmental economics and environmental management in order to arrive at more realistic, empirically grounded models.\n
Given its focus, the book offers a valuable resource for researchers and graduate students with an interest in addressing pollution control challenges in the fields of economics and management science.
