Business Ethics is a Matter of Good Conduct and of Good Conscience?

The myth of an economy where nobody could have a predominant position, has lost its credibility. The presentiment of a high risk of social explosion makes companies undertake tentative moral legitimation. Thus, a new paradigm develops according to which the firm has to care for the satisfaction of public interest if “it wants to try to win forgiveness” for misbehavior towards the decorum rules of the atomicity of competition. Thus, there is a wave of “business ethics industry” building up. However, the stock exchange performances considered as ethical, are not different from others! The market does not seem to be able to say why it might be interesting to invest in stock considered as ethical. Moreover, opinion polls reveal a very significant discrepancy between the characterization of “the responsible company” as defined by itself or by notation agencies and, on the other hand, the hierarchy of criteria according to the answers of polled people. When companies and agencies favor sustainable development and good governance, rejecting child labor and so on, polled people consider that the paramount criterion of ethical conduct is personnel management. The problem is right here. Such is the view of a positively critical economist, situated at the point where macroeconomics meets corporate management.     

Measuring Real Capital Input in OECD Agriculture

This paper provides a farm sector comparison of levels of capital input for 17 OECD countries. The estimates of capital input are derived by representing capital stock as a weighted sum of past investments. The weights correspond to the relative efficiencies of capital goods of different ages, so that the weighted components of capital stock have the same efficiency. We convert estimates of capital stock into estimates of capital services by means of capital rental prices. Comparisons of levels of capital input among countries require data on relative prices of capital input. We obtain relative price levels for capital input among countries via relative investment goods prices, taking into account the flow of capital input per unit of capital stock in each country.
Cet article se propose de comparer le niveau du capital dans Vagriculture de 17pays de l'OCDE. Les estimations du niveau de capital sont déduites en calculant un stock de capital comme une somme pondérée des investissements passés. Les poids utilisés correspondent a Vefficacite relative des biens capitaux à différents âges, de telle sorte que les différentes composantes du stock du capital ait la même efficacité. Le stock de capital est déduit une estimation des services de capital en utilisant un taux de rentabilité. Cette comparaison des niveaux de capital entre pays nécessite des données sur les prix relatifs du capital. Ces prix dépendent des prix relatifs des biens capitaux mais aussi des flux de service générés dans chaque pays par une unité de capital.     

Nonparametric estimation of an instrumental regression: A quasi-Bayesian approach based on regularized posterior

We propose a quasi-Bayesian nonparametric approach to estimating the structural relationship φ$\phi$ among endogenous variables when instruments are available. We show that the posterior distribution of φ$\phi$ is inconsistent in the frequentist sense. We interpret this fact as the ill-posedness of the Bayesian inverse problem defined by the relation that characterizes the structural function φ$\phi$. To solve this problem, we construct a regularized posterior distribution, based on a Tikhonov regularization of the inverse of the marginal variance of the sample, which is justified by a penalized projection argument. This regularized posterior distribution is consistent in the frequentist sense and its mean can be interpreted as the mean of the exact posterior distribution resulting from a Gaussian prior distribution with a shrinking covariance operator.     

On Intersectoral allocations,factors substitutability and multiple long-run growth paths

Summary. This article considers a two-sector model of economic growth with “labour-augmenting” intersectoral external effects stemming from the aggregate capital stock. It is shown that equilibrium balanced growth paths with a non-trivial labour allocation scheme become available. A set of sufficient conditions for the existence of multiple equilibrium growth rays is provided and their determinacy properties are then characterised. Finally, examination of a parameterised C.E.S. economy illustrates the central role of non-unitary values for the elasticity of substitution in the multiplicity issue.

Information revelation in auctions

Auction theory has emphasized the importance of private information to the profits of bidders. However, the theory has failed to consider to what extent initially private information will remain private. We show that in a variety of contexts bidders will reveal their information, even if this information revelation is (ex ante) detrimental to them. Similarly, a seller may reveal her information although this revelation lowers revenues. We also show that bidders may be harmed by private information, even in contexts where more information has traditionally been presumed to be beneficial.     

A DYNAMIC MODEL OF TOURISM, EMPLOYMENT AND WELFARE: THE CASE OF HONG KONG

Abstract.  The present paper uses a dynamic open-economy model with wage indexation to examine the impact of tourism on employment and welfare. Both short-run and long-run situations are analysed. It is well known that tourism converts non-traded goods into tradable goods. An increase in the demand for a non-traded good raises its relative price, which results in an expansion of the non-traded sector at the expense of the traded goods sector. This output shift raises labour employment in the short run. However, in the long run, the higher relative price leads to higher wages, resulting in a negative impact on labour employment. If the output effect is dominant, the expansion in tourism raises employment and welfare. However, under realistic conditions tourism may lower both labour employment and welfare due to rising costs. These results are demonstrated by simulating a dynamic model for the case of Hong Kong.     

Recent Advances in Structural Econometric Modeling: Dynamics, Product Positioning and Entry

In the empirical analysis of consumer markets, recent literature has begun to explore the dynamics in both consumer decisions as well as in firms' marketing policies. Other research has begun to explore the strategic aspects of product line design in a competitive environment. In both cases, structural models have given us new insights into consumer and firm behavior. For example, incorporating consumer and firm dynamics may help explain patterns in our data that are not well-captured by static models. Similarly, the strategic aspects of firm entry and product-positioning may be intrinsically linked to firm conduct and the intensity of competition in a market. Structural analysis of these consumer and firm decisions raise a number of substantial computational challenges. We discuss the computational challenges as well as specific empirical applications. The discussions are based on the session “Structural Models of Strategic Choice” from the 2004 Choice Symposium.     

The Influence of Consumer Involvement in Wine Consumption-Elicited Emotions

There is scarce research on the influence of the level of consumer involvement with wine and consumption-elicited emotions. In this context, we aim to examine whether the level of wine involvement influences the emotional response; and further, whether the level of wine involvement plays a determining role in how emotions drive satisfaction. The study involved a convenience sample through a restaurant and bar intercept survey conducted in La Rioja (Spain). Subsequently, three levels of consumer involvement with wine were examined: low (n?=?316), medium (n?=?387) and highly involved consumers (n?=?462). Then, data were analyzed through structural equation modelling (SEM). Our findings indicate that differing levels of consumer involvement with wine lead to different emotions and satisfaction. Further, consumers should surpass an “involvement threshold” in order to develop a negative emotional appraisal and to provoke negative affect towards wine; but this “involvement threshold” does not apply to the development of pleasant emotions.     

The spatial demography of new plants: urban creation and rural survival

This study shows that the survival rate of new plants depends on their spatial location. A panel dataset of French plants, observed between 1993 and 2002, provides annual samples of more than 300,000 new plants, each plant being defined as rural, peri-urban, urban or located in the Paris region. A survival model is developed, introducing the location variable alongside the usual survival determinants, such as size, industry and period. Estimation results clearly show that it is easier to create a new plant in urban areas, particularly in the Paris region, but less difficult to survive in rural ones. Agglomeration forces may explain the first result, and the intensity of local competition variable, the second. However, even once the local competition effect is controlled, rural new plants still exhibit significantly higher survival rates. The entrepreneurial theory of opportunity may help to understand such a result. The density of population, activities and information offer more opportunities to start an activity, but also to quit it once it has been created.
