Researching taste: an interview of Antoine Hennion

ABSTRACT

Antoine Hennion is a Professor of Sociology at the Centre de Sociologie de l’Innovation (Mines-Paris Tech, PSL/CNRS). He has been researching taste and cultural practices through a pragmatic lens for three decades. He has developed an original and impactful theoretical framework bridging the Actor-Network Theory to Cultural Studies. More precisely, he reconceptualized the notions of mediation and attachment. Antoine Hennion has explored various empirical settings, including music, wine, and sports. More recently, he has contributed to a large research project on migration. His books and academic articles have had an impact on Sociology, and are getting greater attention in consumer research.     

A simple model of brain circulation

This paper analyzes the allocation of two types of individuals differentiated by talent between two countries where they choose to be workers or entrepreneurs. An equilibrium with international migration exists when countries' talent endowments are sufficiently different. It is consistent with one-way or two-way migration whether individuals are entrepreneurs or workers. Although allowing migration increases domestic welfare in one country and decreases it in the other, it is always supported by majority voting in both countries.     

Job protection,housing market regulation,and the youth

Young Europeans experience high unemployment rates, job instability, and late emancipation. Meanwhile, they do not support reforms weakening protection on long‐term contracts. In this paper, we suggest a possible rationale for such reform distaste. When the rental market is strongly regulated, landlords screen applicants with regard to their ability to pay the rent. Protecting regular jobs offers a second‐best technology to sort workers, thereby increasing the rental market size. We provide a model where nonemployed workers demand protected jobs despite unemployment and the share of short‐term jobs increases, whereas the individual risk of dismissal is unaffected. Our theory can be extended to alternative risks and markets involving correlated risks and commitment under imperfect information.     

Disequilibrium,Reproduction and Money: a Classical Approach

We consider a bisector reproduction model in which money is introduced as a pure means of exchange issued by a bank at the producers' requests. Each capitalist aims at maximizing accumulation in his own sector. Their plans are based on available quantities and expected prices. Effective prices are determined by a market mechanism. Temporary disequilibria occur in both physical and monetary terms. The settlement of the monetary balances is operated by means of a transfer of capital goods. Final allocations and effective productions are thus determined. The dynamics of the economy are those of a sequence of temporary disequilibria and let appear several possibilities (local or global stability, cycles) depending on the values of the parameters.     

Agent-Based Reallocation Problem on Social Networks

Resource reallocation problems aim to determine an allocation maximizing a given objective function. Numerous applications are based on the assumption of restricted contacts between entities but, up to now, studies have been based on unrealistic contexts. Indeed, most of the time, agents are omniscient and/or have complete communication abilities, which are not plausible assumptions in many applications. A solution does not only consist in an optimal allocation, but in a sequence of transactions changing an initial allocation into an optimal solution. We show that the individual rationality does not allow the achievement of socially optimal allocations, and we propose a more suitable criterion: the sociability. Our method provides a sequence of transactions leading to an optimal allocation, with any restriction on agents’ communication abilities. Provided solutions can be viewed as emergent phenomena.     

Hinterland transportation in Europe: Combined transport versus road transport

The dominance of road for hinterland services could be challenged by using rail-road or waterway-road transport because of costs, congestion and growing environmental constraints. A common dynamic that is very favorable to the development of combined transport is shared among the actors of the transport chain but with different starting positions considering the ports of the Northern Range.But combined transport must still demonstrate that it can compete with road transport. Road transport and combined transport are not directly comparable because they do not offer the same physical transport service. The organizational patterns of road and combined transport are investigated. The example of hinterland services to and from the port of Le Havre to the Paris region is a particularly interesting case because of the very short distance. It is shown that the competitiveness of combined transport in terms of price varies greatly according to the way road transport it competes with is organized and that the commercial policy of combined transport operators plays a key role for explaining this competitiveness. Additional services such as additional dwelling times and specific custom advantages are paramount of importance to encourage the shift from road transport to combined transport.     

PRIMITIVE ACCUMULATION,GROWTH AND THE GENESIS OF SOCIAL CLASSES

The aim of this paper is to show that inequalities of wealth can be necessary conditions to explain the apparition and rise of a capitalistic system. We try to highlight Marx's insights on primitive accumulation. Our dynamic framework is consistent with Roemer's idea of endogenous class stratification. We extend this calculation by incorporating some features of the Pasinetti–Samuelson–Modigliani model, and provide an example of possible microfoundations.     

How to shake the invisible hand (when Robinson meets Friday)

We propose defining the invisible hand by: (i) modelling the mechanism itself (rather than just assuming its existence); and (ii) making explicit the limit conditions of its working. For that purpose, we simply assimilate the working of the invisible hand mechanism with the existence of a social preference such that individual and social optimalities are consistent. In introducing the possibility of interaction among individuals, we then suggest that the standard "singleton case," or "atomistic individualism," is just an extreme feature of a more general requirement that we call the  network agreement . Our main result is that the invisible hand mechanism does keep on working when there is an interaction between Robinson and Friday if the former (respectively, the latter) is sensitive to the latter (respectively, the former) in such a way that they exhibit some agreement in preferences. Hence, the singleton case naturally satisfies this property because neither Robinson nor Friday can disagree with himself. Further cooperative situations are also allowed in order to extent the invisible hand mechanism to cases with interactions.     

REPRODUCTION AND TEMPORARY DISEQUILIBRIUM: A CLASSICAL APPROACH

We build a bisector reproduction model with Classical features in which the capitalists aim at maximizing accumulation. At variance with gravitation models, it is assumed that they invest their profits in their own industry. Their plans are based on actual productions and expected prices. Effective prices and effective allocations of resources are determined by a market‐clearing mechanism. A law on the formation of expectations allows us to define the dynamics of disequilibria, which let appear endogenous self‐sustained fluctuations around a long‐run path. The long‐run rate of growth and the amplitude of the fluctuations depend on the initial conditions.     

Efficient minimum distance estimation with multiple rates of convergence

This paper extends the asymptotic theory of GMM inference to allow sample counterparts of the estimating equations to converge at (multiple) rates, different from the usual square-root of the sample size. In this setting, we provide consistent estimation of the structural parameters. In addition, we define a convenient rotation in the parameter space (or reparametrization) to disentangle the different rates of convergence. More precisely, we identify special linear combinations of the structural parameters associated with a specific rate of convergence. Finally, we demonstrate the validity of usual inference procedures, like the overidentification test and Wald test, with standard formulas. It is important to stress that both estimation and testing work without requiring the knowledge of the various rates. However, the assessment of these rates is crucial for (asymptotic) power considerations.Possible applications include econometric problems with two dimensions of asymptotics, due to trimming, tail estimation, infill asymptotic, social interactions, kernel smoothing or any kind of regularization.
